RESUMO
BACKGROUND: Retrospective studies and randomized controlled trials support the safety of laparoscopic complete mesocolic excision (CME) for the treatment of right-sided colon cancer (RSCC). Few studies, however, examine the learning curve of this operation and its impact on safety during an implementation period. We aim to evaluate the learning curve and safety of the implementation of laparoscopic CME with intracorporeal anastomosis for RSCC. METHODS: Consecutive patients undergoing a laparoscopic right colectomy with intracorporeal anastomosis for RSCC between January 2016 and June 2023 were included. Clinical, perioperative, and histopathological variables were collected. Correlation and cumulative sum (CUSUM) analyses between the operating time and case number were performed. Breakpoints of the learning curve were estimated using the broken-line model. CME and conventional laparoscopic right colectomy outcomes were compared after propensity score matching (PSM). RESULTS: Two hundred and ninety patients underwent laparoscopic right colectomy during study period. One hundred and eight met inclusion criteria. After PSM, 56 non-CME and 28 CME patients were compared. CME group had a non-statistically significant tendency to a longer operating time (201 versus 195 min; p = 0.657) and a shorter hospital stay (3 versus 4 days; p = 0.279). No significant differences were found in total complication rates or their profile. Correlation analysis identified a significant trend toward operating time reduction with increasing case numbers (Pearson correlation coefficient = - 0.624; p = 0.001). According to the CUSUM analysis, an institutional learning curve was deemed completed after 13 cases and the broken-line model identified three phases: learning (1-6 cases), consolidation (7-13 cases), and mastery (after 13 cases). CONCLUSION: The learning curve of laparoscopic CME for RSCC can be achieved after 13 cases in centers with experience in advanced laparoscopic surgery and surgeons with familiarity with this technique. Its implementation within this setting seems to be as safe as performing a conventional right colectomy.

Introducción: La técnica de resección completa del mesocolon (RCM) en la hemicolectomía derecha consiste en la disección por planos embriológicos para lograr la resección completa del envoltorio mesocolónico, además de una ligadura vascular central (LVC) con linfadenectomía D3, que no se realiza normalmente con la técnica estándar. Esta técnica se asocia a mejores resultados de sobrevida global y libre de enfermedad que la cirugía convencional en trabajos retrospectivos. Sin embargo, no existen datos de su implementación a nivel nacional. El objetivo de este estudio es evaluar los resultados perioperatorios de la implementación del RCM en un centro universitario en nuestro medio. Materiales y Método: Estudio retrospectivo de cohorte de pacientes consecutivos sometidos a hemicolectomía derecha laparoscópica con técnica de RCM-LVC entre Enero 2022 y Junio 2023. Se recopilaron variables demográficas, perioperatorias, postoperatorias e histopatológicas. Los resultados se analizaron utilizando estadística descriptiva. Resultados: En el periodo, 29 pacientes se sometieron a RCM laparoscópica (mediana de edad 66(57-76) y 15(52%) sexo femenino). La mediana del tiempo quirúrgico fue 202,9 minutos. No hubo casos de conversión, filtración anastomótica, ni mortalidad. Hubo morbilidad en 9 casos (31%) y de estos solo 1(3,4%) fue Clavien-Dindo III (hematoma Pfannenstiel reintervenido). No hubo lesiones vasculares intraoperatorias. Mediana de hospitalización de 3 días. Doce casos (41%) eran etapa II y 8(28%) etapa III. La mediana de linfonodos resecados fue 23(18-28). Conclusión: Esta serie demuestra que la implementación de la RCM-LVC por vía laparoscópica para el tratamiento del cáncer de colon derecho y transverso es factible en centros con experiencia en cirugía colorrectal laparoscópica avanzada.
Introduction: Complete mesocolic excision (CME) consists in the dissection on embryologic planes in order to achieve a complete resection of the mesocolic envelope and performing a central vascular ligation (CVL) with a D3 lymphadenectomy which is not routinely done for standard right colectomies. CME has been associated with better overall survival and disease-free survival in comparison with conventional surgery in retrospective studies. However, there is no data on its implementation in Chile. The aim of this study is to assess the perioperative results of the implementation of CME in our center. Methods: A retrospective cohort study was conducted. Consecutive patients undergoing a laparoscopic right hemicolectomy with CME-CVL between January 2022 and June 2023 were included. Demographic, perioperative, postoperative and histopathological data were collected. Results were analyzed using descriptive statistics. Results: During the study period, 34 patients underwent CME; 29 of them underwent laparoscopic CMECVL (median age 66 (57-76) and 15 (52%) female). The median operating time was 202,9 minutes. There were no cases of conversion, anastomotic leakage or mortality. There was morbidity in 9 cases (31%) and one of these (3,4%) was a Clavien-Dindo III morbidity (reoperation due to a Pfannenstiel haematoma). There were no intraoperative vascular injuries. The median length of stay was 3 days. Twelve cases (41%) were stage II and 8(28%) stage III. The median number of lymph nodes harvested was 23(18-28). Conclusion: This series demonstrate that the implementation of laparoscopic CME-CVL for right and transverse colon cancer is feasible in centers with experience in advanced laparoscopic colorectal cancer.
RESUMO
BACKGROUND: Laparoscopic colectomy is widely accepted as a safe operation for colorectal cancer, but we have experienced resistance to the introduction of the FreeHand® robotic camera holder to augment laparoscopic colorectal surgery. AIM: To compare the initial results between conventional and FreeHand® robot-assisted laparoscopic colectomy in Trinidad and Tobago. METHODS: This was a prospective study of outcomes from all laparoscopic colectomies performed for colorectal carcinoma from November 29, 2021 to May 30, 2022. The following data were recorded: Operating time, conversions, estimated blood loss, hospitalization, morbidity, surgical resection margins and number of nodes harvested. All data were entered into an excel database and the data were analyzed using SPSS ver 20.0. RESULTS: There were 23 patients undergoing colectomies for malignant disease: 8 (35%) FreeHand®-assisted and 15 (65%) conventional laparoscopic colectomies. There were no conversions. Operating time was significantly lower in patients undergoing robot-assisted laparoscopic colectomy (95.13 ± 9.22 vs 105.67 ± 11.48 min; P = 0.045). Otherwise, there was no difference in estimated blood loss, nodal harvest, hospitalization, morbidity or mortality. CONCLUSION: The FreeHand® robot for colectomies is safe, provides some advantages over conventional laparoscopy and does not compromise oncologic standards in the resource-poor Caribbean setting.
RESUMO
Objetivo: Describir la experiencia en cirugía colorrectal resectiva laparoscópica en mayores de 75 años durante los años 2004 a 2019 en Clínica INDISA. Material y Método: Estudio transversal de las cirugías electivas por vía laparoscópica en mayores de 75 años, en los que se realizó anastomosis colorrectal, basado en el registro clínico electrónico. Resultados: Un total de 48 cirugías completamente laparoscópicas, la mayoría por cáncer colorrectal (CCR) (89,6%), mostraron indicadores de calidad óptima en la cosecha ganglionar en el 73,2%. Con una mediana de estadía de 6 días y una mortalidad a 30 días de 2,1% (un caso), comparable a las series internacionales. Discusión: El abordaje laparoscópico en pacientes ancianos tiene beneficios por sobre la vía abierta y presenta morbimortalidad aceptable. El balance intraoperatorio entre riesgo/seguridad quirúrgica y pronóstico oncológico es un factor a tener en cuenta en la toma de decisiones, junto con las patologías inherentes al grupo etario y la reserva funcional de cada paciente en particular. Conclusión: Se trata de la primera serie nacional de pacientes sobre 75 años sometidos a cirugía colorrectal resectiva electiva vía laparoscópica. Es factible y seguro en estos pacientes realizar cirugía mínimamente invasiva con morbimortalidad aceptable. La edad por sí sola no representa una contraindicación para la cirugía colorrectal laparoscópica. Es necesario contar con estudios de mayor volumen para conocer mejor la realidad nacional y los resultados a largo plazo.
Objective: To describe the experience in laparoscopic resective colorectal surgery in older than 75 years old, during 2004 to 2019 in INDISA Clinic. Material and Methods: It's a transversal study about all the elective laparoscopic surgeries with colorectal anastomosis in elderly people, based on electronic clinical records. Results: 48 full laparoscopic surgeries, the majority by colorectal cancer (89.6%) shows optimal quality indicators about nodal harvest in 73.2%. The median duration of hospital stay after surgery was 6 days with 30 days mortality of 2.1%. These results are comparable to the international reports. Discussion: The laparoscopic approach in elderly patients has benefits over the open approach with acceptable morbility and mortality. The intraoperatory balance between surgical risk/security and oncologic prognostic it's a factor to consider in the decision-making process besides the morbility by the age and the own functional reserve. Conclusion. It's the first series in Chile about over 75 years patients with laparoscopic resective colorectal surgery. Is feasible and secure to do minimal invasive surgery with acceptable morbility and mortality. Only the age isn't a contraindication to laparoscopic colorectal surgery. It's necessary more studies with mayor number of patients to known better the national results and long-term results.
RESUMO
AIM: The role of bowel preparation before colectomy in Crohn's disease patients remains controversial. This retrospective analysis of a prospective cohort study aimed to investigate the clinical outcomes associated with mechanical and antibiotic colon preparation in patients diagnosed with Crohn's disease undergoing elective colectomy. METHOD: Data were collected from the American College of Surgeons National Surgical Quality Improvement Program participant user files from 2016 to 2021. A total of 6244 patients with Crohn's disease who underwent elective colectomy were included. The patients were categorized into two groups: those who received combined colon preparation (mechanical and antibiotic) and those who did not receive any form of bowel preparation. The primary outcomes assessed were the rate of anastomotic leak and the occurrence of deep organ infection. Secondary outcomes included all-cause short-term mortality, clinical-related morbidity, ostomy creation, unplanned reoperation, operative time, hospital length of stay and ileus. RESULTS: Combined colon preparation was associated with significantly reduced risks of anastomotic leak (relative risk 0.73, 95% CI 0.56-0.95, P = 0.021) and deep organ infection (relative risk 0.68, 95% CI 0.56-0.83, P < 0.001). Additionally, patients who underwent colon preparation had lower rates of ostomy creation, shorter hospital stays and a decreased incidence of ileus. However, there was no significant difference in all-cause short-term mortality or the need for unplanned reoperation between the two groups. CONCLUSION: This study shows that mechanical and antibiotic colon preparation may have clinical benefits for patients with Crohn's disease undergoing elective colectomy.

OBJECTIVE: The purpose of this study was to explore the appropriate surgical procedure and clinical decision for appendiceal adenocarcinoma. METHODS: A total of 1,984 appendiceal adenocarcinoma patients from 2004 to 2015 were retrospectively identified from the Surveillance, Epidemiology, and End Results (SEER) database. All patients were divided into three groups based on the extent of surgical resection: appendectomy (N = 335), partial colectomy (N = 390) and right hemicolectomy (N = 1,259). The clinicopathological features and survival outcomes of three groups were compared, and independent prognostic factors were assessed. RESULTS: The 5-year OS rates of patients who underwent appendectomy, partial colectomy and right hemicolectomy were 58.3%, 65.5% and 69.1%, respectively (right hemicolectomy vs appendectomy, P < 0.001; right hemicolectomy vs partial colectomy, P = 0.285; partial colectomy vs appendectomy, P = 0.045). The 5-year CSS rates of patients who underwent appendectomy, partial colectomy and right hemicolectomy were 73.2%, 77.0% and 78.7%, respectively (right hemicolectomy vs appendectomy, P = 0.046; right hemicolectomy vs partial colectomy, P = 0.545; partial colectomy vs appendectomy, P = 0.246). The subgroup analysis based on the pathological TNM stage indicated that there was no survival difference amongst three surgical procedures for stage I patients (5-year CSS rate: 90.8%, 93.9% and 98.1%, respectively). The prognosis of patients who underwent an appendectomy was poorer than that of those who underwent partial colectomy (5-year OS rate: 53.5% vs 67.1%, P = 0.005; 5-year CSS rate: 65.2% vs 78.7%, P = 0.003) or right hemicolectomy (5-year OS rate: 74.2% vs 53.23%, P < 0.001; 5-year CSS rate: 65.2% vs 82.5%, P < 0.001) for stage II disease. Right hemicolectomy did not show a survival advantage over partial colectomy for stage II (5-year CSS, P = 0.255) and stage III (5-year CSS, P = 0.846) appendiceal adenocarcinoma. CONCLUSIONS: Right hemicolectomy may not always be necessary for appendiceal adenocarcinoma patients. An appendectomy could be sufficient for therapeutic effect of stage I patients, but limited for stage II patients. Right hemicolectomy was not superior to partial colectomy for advanced stage patients, suggesting omission of standard hemicolectomy might be feasible. However, adequate lymphadenectomy should be strongly recommended.

Clostridioidesdifficile infection (CDI) is the culprit of millions of nosocomial infections in the United States. Programs that successfully decrease its incidence, therefore, render cost savings for the healthcare system. Toxic megacolon and perforation are two of the most significant complications with increased mortality rates. We report a 23-year-old nursing home resident hospitalized for fever, cough, and green sputum. After 3 days of antibiotic therapy, he developed abdominal distension, diarrhea, and vomiting and underwent a total colectomy. The colon was dilated to a maximum of 11 cm with markedly edematous mucosa and yellow pseudomembranes. Qualitative PCR of the stool detected Clostridioides difficile toxin B gene. While there is no consensus for the required interval between antibiotic treatment and CDI, this presentation 3 days after starting the antibiotic therapy is earlier than most proposed ranges.
RESUMO
Introducción. La intususcepción del apéndice corresponde a su invaginación en el ciego. Existen varias causas, pero la endometriosis ha sido informada pocas veces. Aunque el diagnóstico se debe sospechar clínicamente, por lo general su causa solo se determina en el intraoperatorio, donde se deben tener en cuenta causas oncológicas que requieran una resección amplia. Caso clínico. Mujer de 21 años que consultó por dolor abdominal agudo generalizado. Se practicó una tomografía computarizada de abdomen, observando una intususcepción del apéndice en el ciego, estriación de la grasa pericecal y adenomegalias. Se realizó laparoscopia diagnóstica encontrando intususcepción casi completa del apéndice cecal, de aspecto neoplásico. Se convirtió a laparotomía para proceder a hemicolectomía derecha, con vaciamiento ganglionar y anastomosis del íleon al colon transverso. Discusión. La sospecha clínica de intususcepción debe corroborarse mediante ecografía, tomografía o estudios baritados. El tratamiento siempre es quirúrgico, como en el caso de nuestra paciente, quien evolucionó de forma adecuada y continuó asintomática después de un año de seguimiento. Conclusión. El diagnóstico temprano de la intususcepción permite realizar tratamientos quirúrgicos menos agresivos y disminuye el riesgo de filtración de la anastomosis. Se debe tener en cuenta el diagnóstico de endometriosis como posible causa. Se debe realizar el manejo complementario por parte de ginecología.
Introduction. The intussusception of the appendix corresponds to its invagination in the cecum. There are several causes, endometriosis being rarely reported. Although the diagnosis must be suspected clinically, its cause is generally only determined intraoperatively, where oncological causes that require extensive resection must be taken into account. Clinical case. A 21-year-old woman who consulted due to acute generalized abdominal pain, an abdominal tomography was performed, finding an intussusception of the appendix in the cecum, striation of pericecal fat, and lymph nodes. A diagnostic laparoscopy was performed, finding almost complete intussusception of the appendix, with a neoplastic appearance. She was converted to laparotomy to perform a right hemicolectomy, with lymph node dissection and ileal to transverse anastomosis. Discussion. Clinical suspicion of intussusception should be confirmed by ultrasound, abdominal tomography, or barium studies. Treatment is always surgical, as in the case of our patient, who evolved adequately and remained asymptomatic after one year of follow-up. Conclusion. Early diagnosis of intussusception allows for less aggressive surgical treatment and decreases the risk of anastomosis leakage. The diagnosis of endometriosis should be taken into account as a possible cause. Complementary management by gynecologists should be performed.

Introducción: El sangrado digestivo intraluminal postoperatorio es una entidad poco frecuente y su manifestación clínica no difiere de la hemorragia digestiva baja de otra etiología. A pesar de que su presentación más habitual es la hematoquecia autolimitada en la primera deposición, en un discreto porcentaje puede requerir transfusiones, tratamiento endoscópico, hemodinámico, o incluso cirugía. Objetivo: Analizar los pacientes con sangrado digestivo intraluminal postoperatorio tratados en un centro de alta complejidad y realizar una revisión bibliográfica del tema. Diseño: Estudio retrospectivo, descriptivo. Material y métodos: Pacientes con sangrado anastomótico durante el post operatorio inmediato de una colectomía izquierda, operados en el Servicio de Cirugía General y Coloproctología desde enero del 2017 a diciembre del 2021. Las variables estudiadas fueron edad, sexo, anticoagulación y su causa, descenso de hemoglobina, cirugía realizada y su indicación, vía de abordaje, configuración de la anastomosis, electividad de la cirugía, complicaciones, días de internación y manejo terapéutico. Resultados: Se incluyeron 4 pacientes con una edad media de 72 (rango 54-87) años y una distribución por sexo de 1:1. En todos la colectomía izquierda fue programada y en 3 el abordaje fue laparoscópico. La anastomosis fue termino-terminal con sutura mecánica circular. Todos los pacientes presentaron sangrado en las primeras 24 horas postoperatorias. El tratamiento fue decidido de acuerdo a la condición hemodinámica: en los 2 pacientes con estabilidad hemodinámica fue suficiente el tratamiento conservador con reanimación y transfusiones. Los otros 2 que presentaron inestabilidad hemodinámica requirieron manejo intervencionista con endoscopía rígida, videocolonoscopía y cirugía. Conclusión: El sangrado intraluminal es una complicación poco frecuente de la anastomosis colorrectal que requiere manejo intervencionista solo en los pacientes que presentan inestabilidad hemodinámica.

Introduction: Postoperative intraluminal gastrointestinal bleeding is a rare entity and its clinical manifestation does not differ from lower gastro-intestinal bleeding of another etiology. Despite the fact that its most common presentation is self-limited hematochezia at the first stool, in a small percentage it may require transfusions, endoscopic or hemodynamic management, or even surgery. Aim: To analyze the patients with postoperative intraluminal gastrointestinal bleeding treated in a tertiary center and to carry out a bibliographic review of the subject. Design: Retrospective descriptive study. Material and methods: Patients with immediate postoperative anastomotic bleeding from a left colectomy, operated on at the General Surgery and Coloproctology Service from January 2017 to December 2021 were included. The variables recorded were age, sex, anticoagulation and its cause, decrease in hemoglobin, procedure performed and its indication, surgical approach, type of anastomosis, electiveness of surgery, complications, hospital stay and management. Results: Four patients with a mean age of 72 (range 54-87) years and a 1:1 gender distribution were included. All procedures were elective and 3 laparoscopic. All anastomoses were performed end-to-end with a circular stapler. All patients presented bleeding in the first 24 postoperative hours. The treatment was decided according to the hemodynamic condition; patients with hemodynamic stability (2) received medical treatment while those with hemodynamic instability (2) required interventional management with rigid endoscopy, colonoscopy and surgery. Conclusion: Intraluminal bleeding is a rare complication of colorectal anastomosis that requires interventional management only in patients with hemodynamic instability. (AU)

El divertículo de Meckel es una malformación congénita que suele presentarse como un hallazgo incidental asintomático. Puede complicarse por procesos inflamatorios o tumores, cursando con sintomatología abdominal sumamente inespecífica, lo que complica su diagnóstico oportuno. Aunque la incidencia de neoplasias malignas en estos divertículos es baja, los tumores neuroendocrinos son los más representativos. Presentamos el caso de una paciente de 72 años que consultó por dolor abdominal y deposiciones melénicas, con múltiples nódulos intrahepáticos sugestivos de tumores neuroendocrinos y hallazgo intraoperatorio incidental de diverticulitis aguda de Meckel con metástasis peridiverticular de un tumor neuroendocrino.

Meckel's diverticulum is a congenital malformation that usually presents as an incidental finding. It can be complicated by inflammatory processes or tumors, with non-specific abdominal symptoms which delay its timely diagnosis. Although the incidence of malignant neoplasms in these diver-ticula is low, neuroendocrine tumors are the most representative. We present the case of a 72-year-old female patient who consulted for abdominal pain and melenic bowel movements, with multiple intrahepatic nodules suggestive of neuroendocrine tumors and an incidental intraoperative finding of acute Meckel's diverticulitis with peridiverticular metastasis of a neuroendocrine tumor.

RESUMO
Introduction: The Deloyers procedure is a valuable technique used in reconstructing bowel transit following an extended left colectomy, a Hartmann-type colostomy, or repeated colon resections. It enables the creation of a tension-free colorectal or coloanal anastomosis. Case presentation: A 60-year-old female patient presented for consultation regarding the closure of a colostomy. Her medical history included segmental colectomy of the sigmoid and descending colon, resulting in a Hartmann-type colostomy due to complicated diverticulitis. The patient underwent laparoscopic surgery, during which a segment of the transverse colon with a short mesocolon was identified. Due to the complete release of the colon, a colorectal anastomosis could not be performed. As an alternative to preserving the ileocecal valve and achieving a tension-free colorectal anastomosis, the patient underwent the Deloyers procedure. Discussion: The Deloyers procedure involves tension-free anastomosis between the right colon and the rectum or anus. It includes complete mobilization and a 180° counterclockwise rotation of the hepatic angle and the right colon. The right and middle colic vessels are divided, while preserving the ileocolic pedicle and the ileocecal valve, thus avoiding the need for total colectomy and ileorectal anastomosis, which may yield unsatisfactory functional outcomes. Conclusion: The Deloyers procedure represents a viable alternative to ileorectal or ileoanal anastomosis, offering satisfactory functional outcomes.
Introducción: el procedimiento de Deloyers es una técnica útil en la reconstrucción del tránsito intestinal posterior a una colectomía izquierda ampliada, colostomía tipo Hartmann o resecciones colónicas iterativas, pues asegura una anastomosis colorrectal o coloanal sin tensión. Presentación del caso: una mujer de 60 años acudió a consulta para el cierre de una colostomía, con antecedente de colectomía segmentaria del sigmoides y colon descendente derivada con colostomía tipo Hartmann por diverticulitis complicada. Fue llevada a cirugía laparoscópica, en la que se encontró un segmento de colon transverso con meso corto y al liberarse completamente no se logró realizar la anastomosis colorrectal, por lo que se decidió realizar el procedimiento de Deloyers como alternativa para conservar la válvula ileocecal y obtener la anastomosis colorrectal libre de tensión. Discusión: el procedimiento de Deloyers consiste en la unión del colon derecho y recto o ano libre de tensión después de realizar la movilización completa y rotación de 180° en sentido antihorario del ángulo hepático y el colon derecho, en el que se seccionan los vasos cólicos derecho y medio, con preservación del pedículo ileocólico y la válvula ileocecal, para evitar la necesidad de una colectomía total y una anastomosis ileorrectal, para la cual los resultados funcionales pueden ser insatisfactorios. Conclusión: el procedimiento de Deloyers es una alternativa viable a la anastomosis ileorrectal o ileoanal con resultados funcionales satisfactorios.
RESUMO
BACKGROUND: Treatment for moderate-severe active ulcerative colitis (UC) includes steroids, biologic therapy and total colectomy. Aim: To describe the features of patients with moderate to severe active UC, their hospital evolution and need for colectomy. MATERIAL AND METHODS: Non-concurrent cohort study of all patients admitted to our institution with a diagnosis of moderate or severe UC crisis between January 2008 and May 2019. Truelove Witts (TW) criteria were used to categorize disease severity. Twelve-month colectomy-free survival was estimated with Kaplan-Meier survival analysis. Results: One hundred-twenty patients aged 16 to 89 (median 35) years had 160 admissions for acute moderate to severe UC. Median admission per patient was 1 (1-3), and median hospital stay was six days (1-49). Cytomegalovirus and Clostridioides difficile were found in 17.5 and 14.2% of crises, respectively. Corticosteroids were used in all crises and biologic therapy in 6.9% of them. Emergency or elective colectomies were performed in 18.3 and 6.7% of patients, respectively. The need for emergency total colectomy decreased from 24.6 to 7.8% (Risk ratio 3.16, p < 0.01) between de first and second half of the study period. Kaplan-Meier analysis for long term colectomy-free survival in both periods confirmed this decrease (p < 0.01). CONCLUSIONS: Medical treatment for moderate to severe UC crises had a 86.3% success and a small percentage required emergency total colectomy. Emergency surgery decreased in the last decade.

INTRODUCTION: Fluorescence-guided surgery has emerged as a complement of traditional laparoscopic surgery with the advantage that is adaptable to existent platforms. The purpose of this article is to describe our technique for ureteral identification with indocyanine green (ICG) during laparoscopic colorectal surgery. MATERIALS AND SURGICAL TECHNIQUE: We report a case series of all patients who underwent laparoscopic colorectal surgery and ureteral injection of ICG in a private third level hospital. RESULTS: We performed 30 laparoscopic colorectal surgeries in which we used this technique to identify the ureters. Mean age was 52.6 ± 15.28 years; 16 (53.3%) were men. The indication for surgery was diverticulitis in 18 patients. Mean urological operative time was 22.4 minutes. There were no immediate or delayed adverse effects attributable to intra-ureteral ICG administration. DISCUSSION: Although ureteric iatrogenic injury is uncommon, when it does happen, it significantly increases the patient's morbidity. We consider this technique has the potential to make laparoscopic surgeries safer mostly in patients with cancer, diverticular disease or endometriosis who have extensive fibrosis, adhesions, and inflammation.

Malakoplakia is a rare granulomatous inflammatory disorder. Its diagnosis depends on histopathological findings; however, high-quality literature regarding proper medical/surgical treatment is lacking. A 38-year-old diabetic female patient was admitted to the emergency room with a history of lower gastrointestinal hemorrhage. Colonoscopy revealed a lesion in the descending colon, and abdominal computed tomography revealed a splenic flexure mass involving the lower pole of the spleen and upper pole of the left kidney. Biopsies confirmed the diagnosis of malakoplakia. After completing antibiotic treatment, a restaging computed tomography revealed a discrete mass increase; hence, the patient underwent laparoscopic en bloc colectomy and partial nephrectomy. Postoperatively, the patient developed a pancreatic fistula, which was successfully treated with percutaneous drainage and antibiotics. The presence of pathognomonic Michaelis-Gutmann inclusions on histopathology is frequently reported as the key to diagnosing malakoplakia. Herein, we present a successful, minimally invasive surgical treatment for colonic malakoplakia.
RESUMO
Introducción: Dentro de las enfermedades neoplásicas el cáncer de colon ocupa sin dudas un lugar preponderante, por ser altamente frecuente. Por ello se hace necesario caracterizar los pacientes con cáncer de colon y contar con un registro real de la incidencia de este problema de salud. Objetivo: Caracterizar el cáncer de colon en pacientes operados en el servicio de Coloproctología del Hospital Universitario Manuel Ascunce Domenech de la provincia Camagüey, en el período comprendido desde septiembre de 2018 hasta septiembre de 2022. Métodos: Se realizó un estudio descriptivo, longitudinal prospectivo con el objetivo de caracterizar el cáncer de colon en pacientes operados en el servicio de Coloproctología en el período comprendido desde septiembre de 2018 hasta septiembre de 2022. El universo lo conformaron todos los pacientes que acudieron a consulta en ese período, la muestra a criterio de los autores la integraron 217 pacientes adultos, con diagnóstico de cáncer de colon operados. La fuente primaria de la investigación estuvo dada por la historia clínica. Resultados: El cáncer de colon se presentó con mayor frecuencia en el grupo etáreo de 60-79 años en ambos sexos, predominó el sexo masculino. El síndrome general fue la sintomatología más frecuente. El diagnóstico se realizó mediante el examen clínico y endoscópico. El adenocarcinoma moderadamente diferenciado tuvo mayor recurrencia. La localización topográfica predominante fue en el colon derecho y la hemicolectomía derecha la técnica quirúrgica más utilizada. Las complicaciones quirúrgicas tuvieron una baja incidencia. Conclusiones: El cáncer de colon presentó una mayor frecuencia en el grupo de etáreo de 60-79 años en ambos sexos. El adenocarcinoma moderadamente diferenciado se presentó en mayor frecuencia. Las complicaciones quirúrgicas fueron infrecuentes con una proporción de uno de cada 10 pacientes.
Introduction: Within neoplastic diseases, colon cancer undoubtedly occupies a preponderant place, because it is highly frequent. For this reason, it is necessary to characterize patients with colon cancer and have a real record of the incidence of this health problem. Objective: To characterize colon cancer in patients operated in the Coloproctology service of the Manuel Ascunce Domenech University Hospital in Camagüey, in the period from September 2018 to September 2022. Methods: A prospective longitudinal descriptive study was carried out with the objective of characterizing colon cancer in patients operated in the Coloproctology service of the Manuel Ascunce Domenech University Hospital, in the period from September 2018 to September 2022. The universe was made up of all the patients who attended the consultation in that period, the sample was to the authors' criteria included 217 adult patients with a diagnosis of colon cancer who underwent surgery. The primary source of the investigation was given by the clinical history. Results: Colon cancer occurred more frequently in the age group of 60-79 years in both sexes, the male sex predominating. The general syndrome was the most frequent symptoms. The diagnosis was made by clinical and endoscopic examination. Moderately differentiated adenocarcinoma had a higher recurrence. The predominant topographic location was in the right colon, and right hemicolectomy was the most widely used surgical technique. Surgical complications had a low incidence. Conclusions: Colon cancer presented a higher frequency in the age group of 60-79 years in both sexes. Moderately differentiated adenocarcinoma occurred more frequently. Right hemicolectomy was the most used surgical technique. Surgical complications were in frequent with a proportion of one in 10 patients.
RESUMO
ABSTRACT BACKGROUND: The laparoscopic approach considerably reduced the morbidity of colorectal surgery when compared to the open approach. Among its benefits, we can highlight less intraoperative bleeding, early oral intake, lower rates of surgical site infection, incisional hernia, and postoperative pain, and earlier hospital discharge. AIMS: To compare the perioperative morbidity of right versus left colectomy for cancer and the quality of laparoscopic oncologic resection. METHODS: Retrospective analysis of patients submitted to laparoscopic right and left colctomy between 2006 and 2016. Postoperative complications were classified using the Clavien-Dindo scale, 30 days after surgery. RESULTS: A total of 293 patients were analyzed, 97 right colectomies (33.1%) and 196 left colectomies (66.9%). The averageage was 62.8 years. The groups were comparable in terms of age, comorbidities, body mass index, and the American Society of Anesthesiology (ASA) classification. Preoperative transfusion was higher in the right colectomy group (5.1% versus 0.4%, p=0.004, p<0.05). Overall, 233 patients (79.5%) had no complications. Complications found were grade I and II in 62 patients (21.1%) and grade III to V in 37 (12.6%). Twenty-three patients (7.8%) underwent reoperation. The comparison between left and right colectomy was not statistically different for operative time, conversion, reoperation, severe postoperative complications, and length of stay. The anastomotic leak rate was comparable in both groups(5.6% versus 2.1%, p=0.232, p>0.05). The oncological results were similar in both surgeries. In multiple logistic regression, ASA statistically influenced the worst results (≥ III; p=0.029, p<0.05). CONCLUSIONS: The surgical and oncological results of laparoscopic right and left colectomies are similar, making this the preferred approach for both procedures.
RESUMO RACIONAL: A abordagem laparoscópica reduziu consideravelmente a morbidade da cirurgia colorretal quando comparada à abordagem aberta. Entre seus benefícios podemos destacar o menor sangramento intraoperatório, ingestão oral precoce, menor índice de infecção de incisão cirúrgica e hérnia incisional, menor índice de dor pós-operatória e alta hospitalar mais precoce. OBJETIVOS: Comparar a morbidade perioperatória da colectomia direita versus esquerda para câncer e a qualidade da ressecção oncológica laparoscópica. MÉTODOS: Análise retrospectiva de pacientes submetidos à olectomia laparoscópica direit e esquerda entre 2006 e 2016. As complicações pós-operatórias foram classificadas pela escala Clavien-Dindo, 30 dias após a cirurgia. RESULTADOS: Um total de 293 pacientes foram analisados, 97 casos de colectomia direita (33.1%) e 196 de esquerda (66.9%). A idade média foi de 62,8 anos. Os grupos foram comparáveis em termos de idade, comorbidades, índice de massa corporal e classificação da Sociedade Americana de Anestesiologia (ASA). A transfusão pré-operatória foi maior no grupo da colectomia direita (5,1% versus 0,4%, p=0,004, p<0,05). No geral, 233 pacientes (79.5%) não apresentaram complicações. As complicações encontradas foram graus I e II em 62 pacientes (21,1%), egraus III a V em 37 (12,6%). Vinte e três pacientes (7,8%) foram reoperados. A comparação entre a colectomia laparoscópica esquerda e direita não foi estatisticamente diferente para tempo operatório, conversão, reoperação, complicações pós-operatórias graves e tempo de internação. A taxa de fístula anastomótica foi comparável em ambos os grupos (5,6% versus 2,1%, p=0,232, p>0,05). Os resultados oncológicos foram semelhantes nas duas cirurgias. Na regressão logística múltipla, a ASA influenciou estatisticamente os piores resultados (≥ III; p=0,029, p<0,05). CONCLUSÕES: Os resultados cirúrgicos e oncológicos das colectomias laparoscópicas direita e esquerda são semelhantes, tornando esta a abordagem preferida para ambos os procedimentos.
RESUMO
ABSTRACT BACKGROUND: Despite major advances in the clinical treatment of inflammatory bowel disease, some patients still present with acute colitis and require emergency surgery. AIMS: To evaluate the risk factors for early postoperative complications in patients undergoing surgery for acute colitis in the era of biologic therapy. METHODS: Patients with inflammatory bowel disease admitted for acute colitis who underwent total colectomy at a single tertiary hospital from 2012 to 2022 were evaluated. Postoperative complications were graded according to Clavien-Dindo classification (CDC). Patients with more severe complications (CDC≥2) were compared with those with less severe complications (CDC<2). RESULTS: A total of 46 patients underwent surgery. The indications were: failure of clinical treatment (n=34), patients' or surgeon's preference (n=5), hemorrhage (n=3), toxic megacolon (n=2), and bowel perforation (n=2). There were eight reoperations, 60.9% of postoperative complications classified as CDC≥2, and three deaths. In univariate analyses, preoperative antibiotics use, ulcerative colitis diagnosis, lower albumin levels at admission, and preoperative hospital stay longer than seven days were associated with more severe postoperative complications. CONCLUSIONS: Emergency surgery for acute colitis was associated with a high incidence of postoperative complications. Preoperative use of antibiotics, ulcerative colitis, lower albumin levels at admission, and delaying surgery for more than seven days were associated with more severe early postoperative complications. The use of biologics was not associated with worse outcomes.
RESUMO RACIONAL: Apesar dos enormes avanços no tratamento das doenças inflamatórias intestinais (DII), alguns pacientes apresentam quadros de colite aguda refratária ao tratamento clínico, e necessitam de cirurgia de urgência. OBJETIVOS: Avaliar os fatores de risco associados com complicações pós-operatórias precoces nos pacientes com colite aguda submetidos a colectomia na era das terapias biológicas. MÉTODOS: Pacientes com DII admitidos com colite aguda grave submetidos a colectomia total em hospital terciário no período de 2012 a 2022 foram analisados. As complicações pós-operatórias foram graduadas de acordo com a classificação Clavien-Dindo (CCD). Pacientes com complicações mais graves (CCD≥2) foram comparados com os menos graves (CCD<2). RESULTADOS: Foram submetidos a cirurgia 46 pacientes. As indicações foram: falha do tratamento conservador (n=34), preferência do paciente ou do cirurgião (n=5), hemorragia (n=3), megacólon tóxico (n=2) e perfuração intestinal (n=2). Reoperação foi necessária em oito pacientes, 60,9% tiveram complicações classificadas como CCD≥2, e três pacientes foram a óbito. Análise univariada identificou que uso de antibióticos no pré-operatório, diagnóstico de colite ulcerativa, hipoalbuminemia na admissão e período de internação maior que sete dias foi associada à complicações pós-operatória mais graves. CONCLUSÕES: Pacientes com colite aguda submetidos a cirurgia de urgência apresentaram alta taxa de complicações pós-operatórias. Uso pré-operatório de antibióticos, diagnóstico de retocolite ulcerativa, hipoalbuminemia na admissão e retardo na operação por mais que sete dias, esteve associado a complicações pós-operatórias mais graves. Uso de biológicos não se associou a piores desfechos.
RESUMO
ABSTRACT Clostridioidesdifficile infection (CDI) is the culprit of millions of nosocomial infections in the United States. Programs that successfully decrease its incidence, therefore, render cost savings for the healthcare system. Toxic megacolon and perforation are two of the most significant complications with increased mortality rates. We report a 23-year-old nursing home resident hospitalized for fever, cough, and green sputum. After 3 days of antibiotic therapy, he developed abdominal distension, diarrhea, and vomiting and underwent a total colectomy. The colon was dilated to a maximum of 11 cm with markedly edematous mucosa and yellow pseudomembranes. Qualitative PCR of the stool detected Clostridioides difficile toxin B gene. While there is no consensus for the required interval between antibiotic treatment and CDI, this presentation 3 days after starting the antibiotic therapy is earlier than most proposed ranges.
RESUMO
Introduction: The second most common cause of cancer-related mortality is colorectal cancer, and laparoscopic-assisted colectomy (LAC) has gained popularity among surgeons as an alternative to the conventional approach, which is open colecrtomy (OC). The differences between LAC and OC in terms of short-term outcomes have not been well documented, and the aim of the present work is to compare the short-term outcomes of both procedures. Materials and Methods: The present prospective study comprised 164 participants submitted to LAC (n = 82) and OC (n = 82) at the Helwan and Zagazig University hospitals between January 2018 and January 2022. We collected and analyzed demographic data, surgical data, and the short-term outcomes. Results: The LAC group had a significantly lower estimated amount of blood loss, shorter hospital stay, lower rates of incisional surgical site infection, and fewer cases of burst abdomen postoperatively, but with a considerably longer operative time (30.3 minutes) than the OC group. Conclusions: Our findings show that LAC is favorable option to OC, with superior outcomes. (AU)
