RESUMEN

INTRODUCTION: Plantar fasciitis is the main cause of heel pain in middle-aged patients. In chronic cases, limited ankle dorsiflexion caused by isolated gastrocnemius contracture is considered the main risk factor for suffering it. Therefore, in recent years the number of patients operated on by proximal fasciotomy of the medial gastrocnemius (FPGM) has increased to treat chronic plantar fasciitis. MATERIAL AND METHODS: Systematic review following the PRISMA guidelines. We have carried out a bibliographic search in Pubmed, Science Direct, Cochrane Library and Web of Science databases. One hundred and eighty-four articles were found. Data extraction was performed using the Covidence software, and a quality and risk of bias analysis of the included articles was performed based on the Cochrane risk of bias Tool 2.0. RESULTS: Three articles were included in the review: two randomised clinical trials and one cohort study with a total of 138 patients. In the analysed studies, patients after proximal fasciotomy of the medial gastrocnemius showed significant improvements in pain and in the AOFAS score with high levels of patient satisfaction. Increases in ankle dorsiflexion angle were found after 12 months of follow-up, with no loss of gastrocnemius strength. The complication rate was low and fewer occurred in the proximal fasciotomy compared to plantar fasciotomy. CONCLUSION: Proximal fasciotomy of the medial gastrocnemius provides clinical benefit in patients with chronic plantar fasciitis, with a low probability of complications and high patient satisfaction.

RESUMEN

Benign prostatic hyperplasia (BPH) is a histopathologic definition associated with enlargement of the prostate gland that causes obstruction of the lower urinary tract and manifests clinically with characteristic symptoms that are what bring patients for consultation. Urinary tract symptoms are common, especially in an increasingly aging population. Diagnosis and the decision on when and how to treat depend on the patient's quality of life and objective clinical parameters. An individualized, risk-based approach is necessary to guide conservative, pharmacologic, or surgical treatment.

RESUMEN

OBJECTIVE: To evaluate the relationship between heart failure (HF), chronic obstructive pulmonary disease (COPD), and smoking with the development of urethral stricture (US) by examining the patients who underwent transurethral prostate resection procedure, with and without the development of US in their follow-ups. METHODS: Among the patients who underwent transurethral resection of the prostate, 50 patients who developed US during their follow-ups formed group 1, while a total of 50 patients who did not develop US and were selected by lot formed group 2. The relationship between the patients' data on HF, COPD and smoking status and the development of US was investigated. RESULTS: The mean number of cigarettes smoked was statistically significantly high in the group with stricture (p = 0.007). Furthermore, pulmonary function test parameters of patients such as forced expiratory volume in 1 s (FEV1), forced vital capacity (FVC), and FEV1/FVC were found to be statistically significantly higher in Group 2 (p < 0.001, p < 0.001, and p = 0.008, respectively). In the logistic regression analysis, being a smoker was found to be the strongest predictor (p = 0.032). CONCLUSION: Our study concluded that smoking, HF, and COPD significantly increase the risk of developing stricture after transurethral resection of the prostate.

OBJETIVO: Evaluar la relación de la insuficiencia cardiaca, la enfermedad pulmonar obstructiva crónica y el tabaquismo con el desarrollo de estenosis de uretra en pacientes sometidos a resección transuretral de próstata con y sin desarrollo de estenosis de uretra en su seguimiento. MÉTODO: Cincuenta pacientes que desarrollaron estenosis de uretra durante su seguimiento formaron el grupo 1, y 50 pacientes que no desarrollaron estenosis de uretra y fueron seleccionados por lote formaron el grupo 2. Se investigó la relación de los datos de los pacientes sobre insuficiencia cardiaca, enfermedad pulmonar obstructiva crónica y tabaquismo con el desarrollo de estenosis uretral. RESULTADOS: La media de cigarrillos fumados fue significativamente más alta en el grupo con estenosis (p = 0.007). Además, se encontró que los parámetros de las pruebas de función pulmonar de los pacientes, como FEV1, FVC y FEV1/FVC, eran significativamente más altos en el grupo 2 (p < 0.001, p < 0.001 y p = 0.008, respectivamente). CONCLUSIONES: El tabaquismo, la insuficiencia cardiaca y la enfermedad pulmonar obstructiva crónica aumentan significativamente el riesgo de desarrollar estenosis después de una resección transuretral de próstata.

RESUMEN

El propósito es presentar una técnica de rinoplastia sin precedentes: la TRICK-TIP (transcolumellar and inter cartilaginous keystoning with tip preservation) usada por 14 años Métodos. La cirugía es indicada en casos estéticos primarios y secundarios y también en reconstructivos como nariz hendida y secuelas de trauma. Una incisión nasal intercartilaginosa se continúa con una vertical en el septum membranoso y se "abre" con una incisión baja en escalera en la parte inferior de la columela, una combinación de elementos de las técnicas abierta y cerrada. La punta nasal se eleva como un colgajo que incluye los alares y la piel vestibular debajo de ellos. El abordaje es muy amplio para realizar todas las maniobras quirúrgicas para septum y dorso, mientras que la punta nasal se preserva anatómicamente y se modifi ca desde abajo por resección cefálica retrógrada de alares, aplicación de poste intercrural fi jado primero arriba y puntos para cierre de espacios muertos en el supra tip, el cierre de las incisiones es sencillo y completo, dos tercios de los casos se realiza resección de alas sin diferimiento. Resultados. Los resultados evaluados por 120 pacientes usando Face Q™, y por 102 evaluadores externos son muy satisfactorios, las complicaciones son bajas y las revisiones infrecuentes. No se presentaron deformidades de triángulos blandos ni de los rebordes de las narinas. De manera subjetiva el autor considera más rápida, barata y fácil esta cirugía mientras que da resultados satisfactorios. Discusión. La TRICK-TIP, una técnica original, convierte la rinoplastia cerrada en una con amplia visibilidad mientras preserva la anatomía de la punta. Su exposición extensa y rapidez permite realizar cambios estructurales complejos en el septum, dorso y vertientes nasales, mientras que maniobras indirectas permiten preservar las uniones interdomales, y proyectar la punta reduciendo espacios muertos. Conclusión. La técnica TRICK-TIP se ha convertido en la preferida del autor debido a su versatilidad y buenos resultados. Ofrece una combinación única de ventajas de los enfoques abiertos y cerrados, con énfasis en la preservación de la punta y la simplifi cación del procedimiento.

The aim is to present an unprecedented rhinoplasty technique, TRICK-TIP (Transcolumellar and Inter Cartilaginous Keystoning with Tip preservation), which has been used for 14 years. Methods:The Surgery is indicated for primary and secondary aesthetic cases, as well as reconstructive such as cleft nose and post-traumatic sequelae. An intercartilaginous endonasal incision is continued with a vertical incision in the membranous septum. It is "opened" with a stair-step incision in the lower part of the columella, combining elements of both open and closed rhinoplasties. The nasal tip is elevated as a composed fl ap that includes the alar cartilages and the vestibular skin beneath them. The approach is extensive to perform all surgical maneuvers for the septum and dorsum while anatomically preserving and modifying the nasal tip from below by retrograde cephalic resection of the alar cartilages, application of an intercrural strut fi xed fi rst superiorly, and closure points for dead spaces in the supratip. The closure of incisions is simple and complete, with two-thirds of cases undergoing alar resection without deferral. Results: The results evaluated by 120 patients using Face Q™ and by 102 external evaluators are highly satisfactory, with low complications and infrequent revisions. Soft triangle deformities or nasal rim deformities were not observed. Subjectively, the author considers this surgery to be faster, cheaper, and easier, yielding satisfactory results. Discussion: The TRICK-TIP, an original technique, transforms closed rhinoplasty into one with extensive visibility while preserving the anatomy of the nasal tip. Its extensive exposure and reduced surgical time allow for complex structural changes in the septum, dorsum, and nasal sidewalls, while indirect maneuvers preserve interdomal junctions and project the tip, reducing dead spaces. Conclusion: The TRICK-TIP technique has become the author's preferred method due to its versatility and good outcomes. It off ers a unique combination of advantages from both open and closed approaches, emphasizing tip preservation and procedural simplifi cation.

RESUMEN

RESUMEN Antecedentes: la duodenopancreatectomía cefálica (DPC) con resección vascular venosa está indicada para el tratamiento del adenocarcinoma ductal y de tumores neuroendocrinos de páncreas, tanto por laparoscopia como por laparotomía. Objetivo: describir los resultados de una serie de pacientes operados de DPC con resección vascular venosa y comparar la morbimortalidad entre los abordados por laparoscopia y por laparotomía. Material y métodos: se realizó un estudio observacional, comparativo, retrospectivo de pacientes con DPC con resección vascular entre enero de 2022 y agosto de 2023. El abordaje laparoscópico fue determinado en menores de 80 años, invasión venosa tumoral igual a 180° o menor en la tomografía, buen performance status, y no haber realizado tratamiento neoadyuvante. Resultados: fueron realizadas 23 DPC con resección vascular venosa: 11 por laparoscopia y 12 por laparotomía. Las 11 realizadas por laparoscopia fueron resecciones laterales, y, en los 12 abordados por laparotomía, se realizó resección total de vena porta en 5 y en el resto, resección lateral. El tiempo de "clampeo" (pinzamiento) portal y la necesidad de transfusiones fue similar en ambos grupos. El estudio patológico reveló R0 en el 78,2% de los pacientes e invasión venosa en el 40.9%. La morbilidad con laparoscopia y con laparotomía consistió, respectivamente, en: fístula pancreática en 7 (4 y 3), vaciamiento gástrico retardado en 4 (1 y 4), fístula biliar en uno (1 y 0), neumonía en dos (1 y 1) e infección de herida en uno (0 y 1). La mortalidad fue de 8,6% por el fallecimiento de dos pacientes, uno en cada grupo. Conclusión: de acuerdo con los criterios empleados, la morbimortalidad de la DPC con resección vascular fue similar por laparoscopia y por laparotomía.

ABSTRACT Background: Cephalic pancreaticoduodenectomy (CPD) with venous resection is indicated for the treatment of ductal adenocarcinoma and neuroendocrine tumors of the pancreas, either through laparoscopy or laparotomy. Objective: The aim of this study was to describe the results of a series of patients undergoing CPD with venous vascular resection and compare morbidity and mortality between the laparoscopic approach and open surgery. Material and methods: We conducted a retrospective, comparative and observational study of patients who underwent CPD with venous vascular resection between January 2022 and July 2023. Criteria for laparoscopic surgery were age < 80 years, interface between tumor and vein of 180° of the circumference of the vessel wall or less on computed tomography, good performance status, and no previous neoadjuvant treatment. Results: A total of 23 CPD procedures with venous vascular resection were performed: 11 by laparoscopy and 12 by laparotomy. The 11 laparoscopic procedures were lateral resections, and in the 12 patients approached by laparotomy, 5 were total portal vein resections and 7 were lateral resections. Portal vein clamping time and need for transfusion was similar in both groups. The pathological examination reported R0 resections in 78.2% and venous invasion in 40.9%. The complications associated with laparoscopy and laparotomy were pancreatic fistula in 4 and 3 patients, respectively, delayed gastric emptying in 1 and 4 patients, respectively, biliary fistula in 1 and 0 patients, respectively, aspiration pneumonia i 1 and 1 patients, respectively and surgical site infection in 0 and 1 patients, respectively. Mortality was 8.6% (n =2), one in each group. Conclusion: According to the criteria used, the morbidity and mortality of CPD with vascular resection were similar for laparoscopy and laparotomy.

RESUMEN

RESUMEN La enfermedad de Caroli es un trastorno congénito causado por malformación de la placa ductal. Se manifiesta con litiasis intrahepática y colangitis recurrente, habitualmente en personas jóvenes. Los hallazgos imagenológicos incluyen dilatación multifocal y segmentaria de los conductos biliares intrahepáticos. El colangiocarcinoma puede aparecer como complicación a largo plazo debido a la inflamación crónica de los conductos, por lo que debe estar siempre presente dentro de los posibles diagnósticos diferenciales. Se describe el caso infrecuente de una mujer de 52 años que presentó un cuadro de obstrucción biliar poscolecistectomía laparoscópica y requirió en su tratamiento quirúrgico la resección de los segmentos hepáticos II y III por enfermedad de Caroli, con buena evolución.

ABSTRACT Caroli's disease is a congenital disorder caused by a defect of the ductal plate. The clinical picture includes intrahepatic duct lithiasis and recurrent cholangitis usually in young people. The imaging tests reveal the presence of multifocal and segmental dilatation of the intrahepatic bile ducts. Cholangiocarcinoma can develop as a long-term complication of chronic bile duct inflammation and should always be considered as a differential diagnosis. We describe a rare case of a 52-year-old woman who presented with bile duct obstruction after laparoscopic cholecystectomy and required resection of liver segments II and III due to Caroli's disease with a favorable outcome.

RESUMEN

INTRODUCTION AND AIMS: Hepatocellular carcinoma (HCC) is a primary malignant tumor of liver epithelial cells and is the most frequent primary liver cancer. The broadening of transplantation and resectability criteria has made therapeutic decisions more complex. Our aim was to describe the clinical and survival characteristics of patients with HCC treated through resection or liver transplantation at our hospital and identify the presence of factors that enable outcome prediction and facilitate therapeutic decision-making. MATERIALS AND METHODS: Patients with HCC that underwent surgery with curative intent at the Hospital Universitario Marqués de Valdecilla, within the time frame of 2007 and 2017, were retrospectively identified. Survival, mortality, disease-free interval, and different outcome-related variables were analyzed. RESULTS: Ninety-six patients with a mean follow-up after surgery of 44 months were included. Overall mortality and recurrence were higher in the resection group. Mean survival was 51.4 months in the liver transplantation group and 37.5 months in the resection group, and the disease-free interval was 49.4 ±â€¯37.2 and 27.4 ±â€¯28.7 months, respectively (p = 0.002). The tumor burden score was statistically significant regarding risk for recurrence and specific mortality. CONCLUSIONS: There appears to be no patient subgroup in whom the results of surgical resection were superior or comparable to those of transplantation. Tumor burden determination could be a useful tool for patient subclassification and help guide therapeutic decision-making.

RESUMEN

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.

RESUMEN

RESUMEN Antecedentes: las metástasis pancreáticas, si bien son poco frecuentes, representan una entidad clínica cuyo diagnóstico probablemente se incrementará en el futuro por el aumento de los programas de seguimiento oncológico. Objetivo: describir los resultados quirúrgicos y oncológicos de una serie de pacientes operados por metástasis pancreáticas. Materiales y métodos: se realizó un estudio de cohorte retrospectivo, descriptivo, multicéntrico, de los pacientes sometidos a resecciones pancreáticas por metástasis entre enero de 2016 y diciembre de 2022, en tres efectores de salud por el mismo grupo quirúrgico. Resultados: fueron operados 19 pacientes, con una media de edad de 59 años (45-79), 11 de sexo femenino, en buen estado general y sin otra evidencia de enfermedad oncológica. El origen de los tumores primarios fue 14 en riñón (7 diagnosticados durante el seguimiento), uno carcinoma mamario, uno melanoma, uno testicular, uno colorrectal y uno de cuello de útero. Las técnicas quirúrgicas empleada fueron: 7 esplenopancreatectomías (5 videolaparoscópicas y 2 convencionales), 4 enucleaciones (3 convencionales y 1 videolaparoscópica), 3 duodenopancreatectomías cefálicas convencionales, 2 duodenopancreatectomías totales convencionales, 2 pancreatectomías centrales convencionales, y una pancreatectomía corporocaudal con preservación del bazo. No se registró mortalidad operatoria (dentro de los 90 días posoperatorios), y presentaron una supervivencia global y libre de enfermedad de 58 y 53 meses, respectivamente. Conclusión: la resección de metástasis pancreáticas, en casos seleccionados, con un abordaje multidisciplinario, y en centros de alto volumen de patología hepatobiliopancreática, es segura y permite buenos resultados oncológicos y de supervivencia global.

ABSTRACT Background: Pancreatic metastases are rare but are likely to be diagnosed more frequently in the future due to the increase in oncology surveillance programs. Objective: The aim of this study was to describe the surgical and oncologic outcomes of a series of patients undergoing surgery for pancreatic metastases. Materials and methods: We conducted a retrospective, descriptive, and multicenter cohort study on patients who underwent pancreatic resections for metastases in the pancreas by the same surgical group between January 2016 and December 2022 in three healthcare providers. Results: A total of 19 patients were operated on, mean age was 59 years (45-79), and 11 were women with good performance status and no other evidence of oncologic disease. Clear cell renal cell carcinoma was the primary tumor in 14 cases (7 diagnosed during surveillance), and the remaining primary tumors were one case of breast ductal carcinoma, one testicular cancer, one colorectal cancer, one melanoma and one cervical cancer. The surgical techniques used were pancreatectomies and splenectomies in 7 patients (5 via laparoscopy and 2 conventional procedures), 4 enucleations (3 conventional procedures and 1 laparoscopic surgery), 3 conventional cephalic pancreaticoduodenectomies, 2 conventional central pancreatectomies and one spleen-preserving distal pancreatectomy. No deaths were reported within 90 days of surgery, and overall survival and disease-free survival were 58 and 53 months, respectively. Conclusion: Resection of pancreatic metastases is safe and provides good oncologic outcomes and overall survival when performed with a multidisciplinary approach in centers with a high volume of hepatobiliary and pancreatic surgeries and in selected cases.

RESUMEN

INTRODUCTION: Controversy exists in the literature as to the best technique for pancreaticoduodenectomy (PD), whether pyloric preservation (PP-CPD) or Whipple's technique (with antrectomy [W-CPD]), the former being associated with a higher frequency of delayed gastric emptying (DGE). METHODS: Retrospective and comparative study between PP-CPD technique (n = 124 patients) and W-CPD technique (n = 126 patients), in patients who were operated for tumors of the pancreatic head and periampullary region between the period 2012 and 2023. RESULTS: Surgical time was longer, although not significant, with the W-CPD technique. Pancreatic and peripancreatic tumor invasion (p = 0.031) and number of lymph nodes resected (p < 0.0001) reached statistical significance in W-CPD, although there was no significant difference between the groups in terms of lymph node tumor invasion. Regarding postoperative morbimortality (medical complications, postoperative pancreatic fistula [POPF], hemorrhage, RVG, re-interventions, in-hospital mortality, Clavien-Dindo complications), ICU and hospital stay, no statistically significant differences were observed between the groups. During follow-up, no significant differences were observed between the groups for morbidity and mortality at 90 days and survival at 1, 3 and 5 years. Binary logistic regression analysis for DGE showed that binary relevant POPF grade B/C was a significant risk factor for DGE. CONCLUSIONS: Postoperative morbidity and mortality and long-term survival were not significantly different with PP-CPD and W-CPD, but POPF grade B/C was a risk factor for DGE grade C.

RESUMEN

Introducción: El proceso diagnóstico de los sarcomas de partes blandas del aparato locomotor (SPBAL) sigue siendo comprometido, con casos de resecciones no planificadas (cirugías «whoops»). Este estudio evalúa la frecuencia de este tipo de procedimientos, tratando de identificar características de los pacientes, tumores, tratamiento quirúrgico y resultados. Material y métodos: Se revisan de forma retrospectiva 131 pacientes tratados de forma quirúrgica en nuestro centro entre octubre de 2018 y diciembre de 2021 de un SPBAL. Se excluyen los pacientes con SPBAL localizados en vísceras, mediastino, corazón, retroperitoneo, peritoneo y aparato genital. Las diferencias entre pacientes con resecciones planificadas y no planificadas fueron evaluadas con pruebas χ2 y un modelo de regresión multivariado de Cox. Resultados: Las resecciones no planificadas de SPBAL han tenido lugar en 18% de los pacientes de nuestra área, principalmente en tumores menos de 5 cm y localizados superficiales a la fascia; 29,2% de estos pacientes no disponían de una prueba de imagen previa. No se ha demostrado que una cirugía «whoops» pueda suponer una disminución de la supervivencia o una mayor tasa de recidivas. Conclusiones: Recomendamos la realización de una prueba de imagen siempre previa a la extirpación de cualquier tipo de tumoración de tejidos blandos, así como la adherencia a las guías de remisión a centros de referencia.(AU)

Introduction: The diagnosis process of soft tissue sarcomas of the musculoskeletal system (SPBAL) continues to be complex, with cases of unplanned excisions (“whoops” surgeries). This study evaluates the frequency of these type of procedures, trying to indentify patient characteristics, tumors, surgical treatment and final results. Material and methods: 131 patients treated surgically between October 2018 and December 2021 of a SPBAL were retrospectively reviewed. Patients with SPBAL located in the viscera, mediastinum, heart, retroperitoneum, peritoneum and genital tract were excluded. Differences between patients with planned and unplanned excisions were assessed with chi2 tests and a Cox multivariate regression model. Results: Unplanned excisions of SPBAL have taken place in 18% of the patients in our área, mainly in tumors of less than 5 cm and located superficial to the fascia. 29,2% of these patients did not have a previous imaging test. It has not been shown that a “whoops” surgery can lead to a decrease in survival or a higher rate of recurrences. Conclusions: We recommend carrying out an imaging test always prior to the removal of any type of soft tissue tumor, as well as adherence to the referral guidelines to reference centers.(AU)

RESUMEN

INTRODUCTION: The objective of the study is to compare 2 techniques for histological handling of rectal cancer specimens, namely whole-mount in a large block vs conventional sampling using small blocks, for mesorectal pathological assessment of circumferential resection margin status and depth of tumor invasion into the mesorectal fat. METHODS: This is a prospective study including 27 total mesorectal excision specimens of rectal cancer from patients treated for primary rectal carcinoma between 2020 and 2022 in a specialized multidisciplinary Colorectal Unit. For each total mesorectal excision specimen, 2 contiguous representative tumoral slices were selected and comparatively analyzed with whole-mount and small blocks macroscopic dissection techniques, enabling comparison between them in the same surgical specimen. The agreement between the 2 techniques to assess the distance of the tumor from the circumferential resection margin as well as the depth of tumor invasion was evaluated with the Student's t-test for paired samples, Pearson's correlation coefficient, and the Bland-Altman method comparison analysis. RESULTS: Complete mesorectal excision was observed in 8% of cases. Circumferential resection margin involvement was observed in only one case (4 %). The whole-mount and small block techniques obtained similar results when we assessed the distance to the circumferential resection margin (t-test P = 0.8, r = 0.92) and the depth of mesorectal infiltration (t-test P = 0.6, r = 0.95). CONCLUSIONS: Both gross dissection techniques (whole-mount vs multiple small cassettes) are equivalent and reliable to assess the distance to circumferential resection margin and the depth of mesorectal infiltration in the mesorectal fat in rectal cancer staging.

RESUMEN

La isquemia intestinal aguda es una emergencia vascular provocada por fenómenos oclusivos y no oclusivos de la circulación mesentérica arterial y venosa, de difícil diagnóstico y pronóstico ominoso. Su incidencia va en aumento paulatino con el decurso de los años, asociada fundamentalmente al envejecimiento de la población. La tasa de mortalidad es elevada a pesar de los avances en el campo de la imagenología. Suele diagnosticarse de forma tardía, cuando está establecido el daño isquémico intestinal de carácter irreversible. El elemento imprescindible e indispensable lo constituye el tiempo que trascurre hasta la cirugía, por lo que su diagnóstico sigue siendo un reto clínico. El tratamiento exige medidas médicas intensivas, al igual que cirugía de revascularización y resección del intestino necrosado. Por desdicha, el examen físico y los hallazgos de laboratorio no son sensibles ni específicos para su diagnóstico. Teniendo en cuenta estos elementos, se presenta el caso de una paciente de 38 años con clínica difusa de vómitos, diarrea y dolor abdominal progresivo, que requirió intervención quirúrgica de urgencia con diagnóstico transoperatorio de isquemia mesentérica aguda. Durante su estancia hospitalaria se relaparotomizó en dos ocasiones, mantuvo soporte ventilatorio e inotrópico por fallo multiorgánico en la Unidad de Cuidados Intensivos, mostrando una adecuada evolución posquirúrgica. El objetivo de esta presentación es enfatizar en la clínica como elemento fundamental para abordar de forma correcta esta entidad en un medio hospitalario de limitados recursos diagnósticos imagenológicos, al abordar conceptos teóricos recientes y facilitar una adecuada actuación en la toma de decisiones.

Acute intestinal ischemia is a vascular emergency caused by occlusive and non-occlusive phenomena of the mesenteric arterial and venous circulation of difficult diagnosis and ominous prognosis. Its incidence is gradually increasing over the years, mainly associated with the ageing of the population. The mortality rate is high despite advances in the field of imaging. It is usually diagnosed late, when irreversible ischemic intestinal damage is established. The essential and indispensable element is the time that elapses until surgery, so its diagnosis continues to be a clinical challenge. Treatment requires intensive medical measures, as well as revascularization surgery and resection of the necrotic intestine. Unfortunately, physical examination and laboratory findings are neither sensitive nor specific for its diagnosis. Taking these elements into account, the authors present the case of a 38-year-old female patient with diffuse symptoms of vomiting, diarrhea and progressive abdominal pain that required emergency surgery with intraoperative diagnosis of acute mesenteric ischemia. During her hospital stay, she underwent re-laparotomy twice, maintained ventilatory and inotropic support due to multi-organ failure in the Intensive Care Unit, showing an adequate post-surgical evolution. The objective of this presentation is to emphasize in the clinic as a fundamental element to correctly address this entity in a hospital environment with limited imaging diagnostic resources by addressing recent theoretical concepts and facilitating adequate action in decision-making.

RESUMEN

Crohn's disease (CD) frequently requires surgery due to complications. Although traditionally reserved for complicated cases, primarily ileocecal early intestinal resection is gaining interest as an initial treatment. Studies suggest that early intestinal resection reduces relapses and the need for biological therapy compared to initial medical treatment. However, more research is needed to evaluate its long-term impact in real-world clinical practice

La enfermedad de Crohn (EC) frecuentemente requiere cirugía debido a complicaciones. Aunque tradicionalmente se reserva para casos complicados, la resección intestinal temprana (RIT) a nivel ileocecal está ganando interés como tratamiento inicial. Estudios sugieren que la RIT reduce recaídas y la necesidad de terapia biológica comparado con el tratamiento médico inicial. Sin embargo, se necesita más investigación para evaluar su impacto a largo plazo en la práctica clínica real.

RESUMEN

INTRODUCTION: The improved image resolution of IMAGE1 S technology will increase tumor detection, achieve a greater number of complete resections, and would probably have an impact on the reduction of recurrences. AIM: The primary objective was to compare the recurrence rates of IMAGE1 S vs. white light during transurethral resection of the bladder (TUR); the secondary objective was to compare the complication rates according to Clavien-Dindo (CD) at 12 months of follow-up. METHODS: Prospective, randomized 1:1, blinded clinical trial. Recurrence and complication rates according to CD were analyzed using chi-square/U Mann-Whitney tests and recurrence-free survival (RFS) using Kaplan-Meier curves. The European Association of Urology (EAU) 2021 scoring model was used. RESULTS: The analysis included 103 participants; 49 were assigned to the IMAGE1 S group and 54 to the white light group. Recurrence rates were 12.2% and 25.9%, respectively (P = .080). The low and intermediate risk group had a lower recurrence rate with IMAGE1 S (7.7% vs. 30.8%, P = .003) and a higher RFS with IMAGE1 S (85.2% vs. 62.8% Log Rank: 0.021), with a Hazard Ratio of 0.215 (95% CI: 0.046-0.925). No differences were observed in the high and very high-risk groups. Complications were mostly grade I and rates were similar between both groups (IMAGE1 S 20.4% vs. white light 7.4% P = .083). CONCLUSIONS: There were no differences in the recurrence rates between groups. However, the low and intermediate risk group had a lower recurrence rate with IMAGE1 S. In addition, perioperative complication rates were not higher.

RESUMEN

The lymphangioma is a rare and very uncommon benign tumor at the gastric level. Its diagnosis typically involves imaging tests and endoscopy, and its treatment usually involves surgery. We present a case of an 82-year-old patient who presented with chronic anemia, with a large gastric polyp detected during the initial gastroscopy. Subsequently, an endoscopic resection was performed, confirming histologically that it was a lymphangioma.(AU)
