RESUMO
Laryngeal hemangiomas are rare vascular tumors, mainly in children, and less common in adults. Giant lesions typically require multiple endoscopic procedures and temporary tracheostomy. Open surgery allows single-procedure removal with fewer complications. CO2 laser excision controls bleeding and minimizes tissue damage. This study evaluates this hybrid approach to manage adult giant supraglottic hemangiomas. A 54-year-old woman with a giant supraglottic hemangioma was successfully treated using a combination of open surgery and CO2 laser. Limited data on adult laryngeal hemangiomas result in a lack of established treatment protocols. For giant supraglottic hemangiomas, combining open surgery with CO2 laser resection offers distinct advantages: enhanced lesion visibility, optimal airway control, effective hemostasis, reduced tissue damage, and lower recurrence rates. This hybrid approach also supports rapid recovery and favorable clinical outcomes. Combining open surgical excision with CO2 laser is effective for managing giant supraglottic hemangiomas in adults.
RESUMO
Brain Arteriovenous Malformations (bAVMs) are rare but high-risk developmental anomalies of the vascular system. Microsurgery through craniotomy is believed to be the mainstay standard treatment for many grades of bAVMs. However, a significant challenge emerges in the existing body of clinical studies on open surgery for bAVMs: the lack of reproducibility and comparability. This study aims to assess the quality of studies reporting clinical and surgical outcomes for bAVMs treated by open surgery and develop a reporting guideline checklist focusing on essential elements to ensure comparability and reproducibility. This is a systematic literature review that followed the PRISMA guidelines with the search in Medline, Embase, and Web of Science databases, for studies published between January 1, 2018, and December 1, 2023. Included studies were scrutinized focusing on seven domains: (1) Assessment of How Studies Reported on the Baseline Characteristics of the Patient Sample; (2) Assessment and reporting on bAVMs grading, anatomical characteristics, and radiological aspects; (3) Angioarchitecture Assessment and Reporting; (4) Reporting on Pivotal Concepts Definitions; (5) Reporting on Neurosurgeon(s) and Staff Characteristics; (6) Reporting on Surgical Details; (7) Assessing and Reporting Clinical and Surgical Outcomes and AEs. A total of 47 studies comprising 5,884 patients were included. The scrutiny of the studies identified that the current literature in bAVM open surgery is deficient in many aspects, ranging from fundamental pieces of information of methodology to baseline characteristics of included patients and data reporting. Included studies demonstrated a lack of reproducibility that hinders building cumulative evidence. A bAVM Open Surgery Reporting Guideline with 65 items distributed across eight domains was developed and is proposed in this study aiming to address these shortcomings. This systematic review identified that the available literature regarding microsurgery for bAVM treatment, particularly in studies reporting clinical and surgical outcomes, lacks rigorous scientific methodology and quality in reporting. The proposed bAVM Open Surgery Reporting Guideline covers all essential aspects and is a potential solution to address these shortcomings and increase transparency, comparability, and reproducibility in this scenario. This proposal aims to advance the level of evidence and enhance knowledge regarding the Open Surgery treatment for bAVMs.

RESUMEN El aneurisma de aorta abdominal (AAA) sintomático no roto es una patología que involucra a aquellos pacientes con AAA intacto, pero que presentan dolor abdominal y/o lumbar atribuido al aneurisma. Esta forma de presentación clínica es po tencialmente mortal dado que su etiopatogenia comprende cambios agudos en la pared aórtica, incluyendo inflamación, lo que incrementa la probabilidad de ruptura inminente. Está claro que estos pacientes deben ser derivados a reparación del AAA. Sin embargo, el momento de la intervención es controvertido. Por lo tanto, el objetivo del presente trabajo fue revisar la información actualizada sobre el abordaje diagnóstico-terapéutico del AAA sintomático no roto.
ABSTRACT Symptomatic unruptured abdominal aortic aneurysm (AAA) refers to a group of patients with intact AAA but who present abdominal and/or lumbar pain attributed to the aneurysm. This form of clinical presentation is potentially fatal since its etiopathogenesis, involving acute changes in the aortic wall, including inflammation, increases the probability of impending rupture. It is clear that these patients should be referred to AAA repair. However, the timing of the intervention is contro versial. Therefore, the aim of the present work was to review updated information on the diagnostic-therapeutic approach of symptomatic unruptured AAA.
RESUMO
Introducción. La colecistectomía laparoscópica es el estándar de oro para el manejo de la patología de la vesícula biliar con indicación quirúrgica. Durante su ejecución existe un grupo de pacientes que podrían requerir conversión a técnica abierta. Este estudio evaluó factores perioperatorios asociados a la conversión en la Clínica Central OHL en Montería, Colombia. Métodos. Estudio observacional analítico de casos y controles anidado a una cohorte retrospectiva entre 2018 y 2021, en una relación de 1:3 casos/controles, nivel de confianza 95 % y una potencia del 90 %. Se caracterizó la población de estudio y se evaluaron las asociaciones según la naturaleza de las variables, luego por análisis bivariado y multivariado se estimaron los OR, con sus IC95%, considerando significativo un valor de p<0,05, controlando variables de confusión. Resultados. El estudio incluyó 332 pacientes, 83 casos y 249 controles, mostrando en el modelo multivariado que las variables más fuertemente asociadas con la conversión fueron: la experiencia del cirujano (p=0,001), la obesidad (p=0,036), engrosamiento de la pared de la vesícula biliar en la ecografía (p=0,011) y un mayor puntaje en la clasificación de Parkland (p<0,001). Conclusión. La identificación temprana y análisis individual de los factores perioperatorios de riesgo a conversión en la planeación de la colecistectomía laparoscópica podría definir qué pacientes se encuentran expuestos y cuáles podrían beneficiarse de un abordaje mínimamente invasivo, en búsqueda de toma de decisiones adecuadas, seguras y costo-efectivas
Introduction. Laparoscopic cholecystectomy is the gold standard for the management of gallbladder pathology with surgical indication. During its execution, there is a group of patients who may require conversion to the open technique. This study evaluated perioperative factors associated with conversion at the OHL Central Clinic in Montería, Colombia. Methods. Observational analytical case-control study nested in a retrospective cohort between 2018 and 2021, in a 1:3 case/control ratio, 95% confidence level and 90% power. The study population was characterized and the associations were evaluated according to the nature of the variables, then the OR were estimated by bivariate and multivariate analysis, with their 95% CI, considering a value of p<0.05 significant, controlling for confounding variables. Results. The study included 332 patients, 83 cases and 249 controls, showing in the multivariate model that the variables most strongly associated with conversion were: the surgeon's experience (p=0.001), obesity (p=0.036), gallbladder wall thickening on ultrasonography (p=0.011), and a higher score in the Parkland classification (p<0.001). Conclusions. Early identification and individual analysis of the perioperative risk factors for conversion in the planning of laparoscopic cholecystectomy could define which patients are exposed, and which could benefit from a minimally invasive approach, in search of making safe, cost-effective, and appropriate decisions

The six million inhabitants of these diverse English-speaking Caribbean countries are grateful to the University of the West Indies, which has been central in the independent training of surgical specialists in all areas of surgery for the past 50 years. Similar to the per capita income, the quality of surgical care, albeit acceptable, is quite variable throughout the region. Globalization and access to information have revealed that the quality of training and surgical care being delivered can be further improved. Technological advances will perhaps never be on par with higher-income countries, but collaborative ventures with global health partners and institutions can ensure that the people of the region will have appropriately trained surgical doctors and, therefore, the provision of accessible quality care will remain a staple, with even the possibility of income generation. This study reviews the journey of our structured surgical training program delivered in the region and outlines our growth plans.
RESUMO
BACKGROUND: Gallbladder carcinoma (GC) is a rare malignant tumor. Laparoscopic technology has revolutionized the reality of surgery. However, whether laparoscopic surgery is suitable for GC has not been clarified. We aimed to analyze the safety, feasibility, and oncological outcomes of laparoscopic surgery in GC. METHODS: The medical records of patients with GC treated at our hospital between January 2016 and December 2021 were retrospectively reviewed. Patients who underwent laparoscopic and open surgery were compared. Propensity score matched analysis was performed to balance the basic characteristics of the two groups. Kaplan-Meier curves were used to describe and compare the overall and disease-free survival rates between the groups. RESULTS: A total of 163 patients with GC were included. Cholelithiasis was detected in 64 (39.3%) patients. Seventy patients were matched after propensity score matching. The laparoscopic group was significantly better than the open group in terms of operation time (p < 0.001), blood loss (p = 0.002), drain time (p = 0.001), and hospital stay (p < 0.001). After a median follow-up time of 19 (12, 35) months, there was no significant difference in the cumulative overall (p = 0.650) and disease-free (p = 0.663) survival rates between the laparoscopic and open groups according to Kaplan-Meier curves. CONCLUSION: Laparoscopic surgery can reduce the operation time and blood loss, and shorten drain time and hospital stay without increasing the incidence of complications. Patients undergoing laparoscopic and open surgery have a similar prognosis. Laparoscopic surgery is worth promoting in patients with GC.

ABSTRACT BACKGROUND: Laparoscopic appendectomy is the gold standard surgical procedure currently performed for acute appendicitis. The conversion rate is one of the main factors used to measure laparoscopic competence, being important to avoid wasting time in a laparoscopic procedure and proceed directly to open surgery. AIMS: To identify the main preoperative parameters associated with a higher risk of conversion in order to determine the surgical method indicated for each patient. METHODS: Retrospective study of patients admitted with acute appendicitis who underwent laparoscopic appendectomy. A total of 725 patients were included, of which 121 (16.7%) were converted to laparotomy. RESULTS: The significant factors that predicted conversion, identified by univariate and multivariate analysis, were: the presence of comorbidities (OR 3.1; 95%CI; p<0.029), appendicular perforation (OR 5.1; 95%CI; p<0.003), retrocecal appendix (OR 5.0; 95%CI; p<0.004), gangrenous appendix, presence of appendicular abscess (OR 3.6; 95%CI; p<0.023) and the presence of difficult dissection (OR 9.2; 95%CI; p<0.008). CONCLUSIONS: Laparoscopic appendectomy is a safe procedure to treat acute appendicitis. It is a minimally invasive surgery and has many advantages. Preoperatively, it is possible to identify predictive factors for conversion to laparotomy, and the ability to identify these reasons can aid surgeons in selecting patients who would benefit from a primary open appendectomy.
RESUMO RACIONAL: A apendicectomia laparoscópica é o procedimento cirúrgico padrão-ouro realizado atualmente para apendicite aguda. A taxa de conversão é um dos principais fatores utilizados para medir a competência laparoscópica, e importante para evitar perda de tempo em um procedimento laparoscópico e proceder diretamente à cirurgia aberta. OBJETIVO: Identificar os principais parâmetros pré-operatórios associados ao maior risco de conversão para determinar o método cirúrgico indicado para cada paciente. MÉTODOS: Estudo retrospectivo de pacientes admitidos com apendicite aguda, submetidos a apendicectomia laparoscópica. Foram incluídos 725 pacientes, sendo que destes, 121 (16,7%) foram convertidos para laparotomia. RESULTADOS: Os fatores significativos que predizem a conversão, identificados por análise univariada e multivariada, foram: presença de comorbidades (OR 3,1; IC95%; p<0,029), perfuração apendicular (OR 5,1; IC95%; p<0,003), apêndice retrocecal (OR 5,0; IC95%; p<0,004), apêndice gangrenoso, presença de abscesso apendicular (OR 3,6; IC95%; p<0,023) e a presença de dissecção difícil (OR 9,2; IC95%; p<0,008). CONCLUSÕES: A apendicectomia laparoscópica é um procedimento seguro para tratar apendicite aguda. É uma cirurgia minimamente invasiva e tem muitas vantagens. No pré-operatório, é possível identificar os fatores preditores de conversão para laparotomia, e a capacidade de identificar essas razões pode ajudar os cirurgiões na seleção de pacientes que se beneficiariam de uma apendicectomia aberta primária.

Context: The advantages of minimally invasive surgery for radical prostatectomy (RP) have been demonstrated in a number of systematic reviews (SRs). However, the rigorous study selection process for SR means that a lot of information can be excluded, leading to a very specific clinical scenario that is often unrepresentative of real life. Our new reverse SR methodology generates a heterogeneous population database that covers a wide range of clinical scenarios. Objective: To compare perioperative surgical results and complications for open retropubic RP (RRP), laparoscopic RP (LRP), and robot-assisted RP (RARP) in a reverse SR. Evidence acquisition: Eight databases were searched for SRs on RRP, LRP, or RARP between 2000 and 2020 (80 SRs). All references used in these SRs were captured for analysis (1724 articles). Perioperative outcomes and complications were compared among the RRP, LRP, and RARP approaches. Evidence synthesis: We identified 559 (32.4%) reports on RRP, 413 (23.9%) on LRP, and 752 (43.7%) on RARP, involving 1 353 485 patients overall. RARP showed a significantly higher annual volume of surgery per surgeon (AVSS) in comparison to RRP and LRP (mean 64.29, 43.26, and 41.47, respectively), a higher percentage of low-risk patients (prostate-specific antigen <10 ng/ml, Gleason <7, stage
RESUMO
BACKGROUND: Robotic gastrectomy (RG) has been shown to be a safe and feasible method in gastric cancer (GC) treatment. However, most studies are in Eastern cohorts and there is great interest in knowing whether the method can be used routinely, especially in the West. OBJECTIVES: The aim of this study was to compare the short-term surgical outcomes of D2-gastrectomy by RG versus open gastrectomy (OG). METHODS: Single-institution, open-label, non-inferiority, randomized clinical trial performed between 2015 and 2020. GC patients were randomized (1:1 allocation) to surgical treatment by RG or OG. Da Vinci Si platform was used. INCLUSION CRITERIA: gastric adenocarcinoma, stage cT2-4 cN0-1, potentially curative surgery, age 18-80 years, and ECOG performance status 0-1. EXCLUSION CRITERIA: emergency surgery and previous gastric or major abdominal surgery. Primary endpoint was short-term surgical outcomes. The study is registered at clinicaltrials.gov (NCT02292914). RESULTS: Of 65 randomized patients, 5 were excluded (3 palliatives, 1 obstruction and emergency surgery, and 1 for material shortage). Consequently, 31 and 29 patients were included for final analysis in the OG and RG groups, respectively. No differences were observed between groups regarding age, sex, BMI, comorbidities, ASA, and frequency of total gastrectomy. RG had similar mean number of harvested lymph nodes (p = 0.805), longer surgical time (p < 0.001), and less bleeding (p < 0.001) compared to OG. Postoperative complications, length of hospital stay, and readmissions in 30 days were equivalent between OG and RG. CONCLUSIONS: RG reduces operative bleeding by more than 50%. The short-term outcomes were non-inferior to OG, although surgical time was longer in RG.

Introducción. La frecuencia de complicaciones postquirúrgicas de la colecistectomía realizada en la noche es un tema de controversia, siendo que se ha reportado una frecuencia mayor durante el horario nocturno. El objetivo de este estudio fue analizar la presentación de colecistectomía difícil dependiendo de la hora en que se realizó la cirugía, además de otras complicaciones, estancia intrahospitalaria postquirúrgica, reingreso a 30 días y reintervención. Métodos. Se realizó un estudio retrospectivo, observacional, analítico y transversal, comparando la presentación de colecistectomía difícil y su frecuencia en horario diurno (8:00 am a 7:59 pm) y nocturno (8:00 pm a 7:59 am), además de seroma, absceso, hematoma, fuga biliar, biloma, estancia intrahospitalaria postquirúrgica, reingreso a 30 días y reintervención. Resultados. Se incluyeron en el estudio 228 pacientes, 117 operados durante el día (52 %) y 111 durante la noche (48 %). La colecistectomía difícil se presentó 26 % vs 34 % de los casos intervenidos en el día y la noche, respectivamente. La complicación más frecuente fue seroma (14 %). La estancia hospitalaria media fue de 2,7 días en cirugías diurnas y de 2,5 en cirugías nocturnas; hubo 3 % de reintervenciones y 6 %, respectivamente. También hubo 2 % de reingresos a los 30 días entre los pacientes operados en el día y 3 % entre los operados en la noche. Conclusiones. La frecuencia de colecistectomía difícil y las complicaciones, la estancia intrahospitalaria postquirúrgica, el reingreso a 30 días y la necesidad de reintervención, no tuvieron diferencias significativas respecto al horario de la cirugía.
Introduction. The frequency of post-surgical complications of cholecystectomy performed overnight is a matter of controversy, and a higher rate has been reported during the night shift. The objective of this study was to analyze the presentation of difficult cholecystectomy depending on the time the surgery was performed, in addition to other complications, postoperative hospital stay, 30-day readmission, and reintervention. Methods. A retrospective, observational, analytical and cross-sectional study was carried out, comparing the presentation of difficult cholecystectomy and its frequency during daytime (8:00 am to 7:59 pm) and at night (8:00 pm to 7:59 am), in addition of seroma, abscess, bile leak, biloma, hematoma, post-surgical hospital stay, 30-day readmission, and reintervention.Results. A total of 228 patients were included in the study, 117 patients operated during the day (52%), and 111 at night (48%). Difficult cholecystectomy occurred in 26% vs. 34% of the cases operated on during the day and at night, respectively. The most frequent complication was seroma (14%). The mean hospital stay was 2.7 days in day surgeries and 2.5 in night surgeries; there were also 2% readmission at 30 days among patients operated during the day and 3% among those operated on at night. Conclusions. The frequency of difficult cholecystectomy and complications, postoperative hospital stay, 30-day readmission, and the need of reintervention, did not have significant differences with respect to the time of surgery.

Background: Laparoscopic cholecystectomy is a common operation worldwide, with low mortality (0.01%) and morbidity (2-8%). It has been reported 2.9 to 3.2% of elective laparoscopic cholecystectomies are converted to open surgery. Converted cases are associated with increased complications rates. Method: Two thousand and seventy-five patients, 82.8% females and 17.2% males who underwent elective laparoscopic cholecystectomy in our hospital, between March 1, 2016, and February 28, 2018, were prospectively collected in a database. Pearson's Chi-squared and Fisher's exact tests were used to determine significance, with p <0.05 deemed statistically significant. We analyzed seven risk factors associated with conversion to open surgery; age, gender, body mass index (BMI), previous abdominal surgeries, the presence of contracted gallbladder, Mirizzi syndrome, or choledocholithiasis. Laparoscopic cholecystectomy was performed using a 3-port technique (73%) and a 4-port technique (27%). Results: Finding associated "strong" factors to conversion: male patients, >60-years-old, previous upper abdominal surgery, contracted gallbladder, Mirizzi syndrome or choledocholithiasis. The presence of a higher or lower BMI did not influence the rate of conversion. The most impact association were males over 60 years, and males with an earlier upper abdominal surgery. Conclusion: Laparoscopic cholecystectomy is the gold standard for gallstones and gallbladder disease; however, inflammation, adhesions, and anatomic difficulty continue to challenge the use and safety of this approach in a small number of patients. This study identifies predictors of choice for open cholecystectomy. In view of the raised morbidity and mortality associated with open cholecystectomy, distinguishing these predictors will serve to decrease the rate of conversion and address these factors preoperatively.

RESUMO
INTRODUCTION: With the increase in life expectancy and consequent aging of the population, degenerative lumbar spine diseases tend to increase its number exponentially. Several treatment options are available to treat degenerative spinal diseases, such as laminectomies, posterior fusions, and interbody fusions, depending on their locations, correction necessities, and surgeon philosophy. With the advance in technology and surgical knowledge, minimally invasive techniques (MIS) arose as a solution to reduce surgical morbidity, while maintaining the same benefits as the traditionally/open surgeries. Several studies investigated the possible advantages of MIS techniques against the traditional open procedures. However, those articles are usually focused only on one technique or on one pathology. METHODS: The electronic databases, including PubMed, Google Scholar, Ovid, and BVS, were systematically reviewed. Only original articles in English or Portuguese were added to the review, the revision was performed following the PRISMA guideline. RESULTS: Fifty-three studies were included in the meta-analysis. Of the studied outcomes the Length of Stay Odds of complications, Blood Loss, and Surgery costs presented significantly favored MIS approaches, while the Last FUP ODI score, and Surgery Time did not differ among the groups. CONCLUSION: Minimally invasive techniques are a remarkably interesting option to traditional open surgeries, as these procedures showed a significant reduction in blood loss, hospitalization time, complications, and surgical costs.

INTRODUCTION: Colorectal cancer is the second most frequent cause of deaths from cancer worldwide. Enhanced recovery protocols (ERPs) were developed in 90s to improve the recovery of these patients. Within ERPs, this work aims to compare immune response between open and laparoscopic procedures to support the best surgical approach. MATERIALS AND METHODS: The immune status of 148 patients undergoing colorectal surgery (74 by laparoscopic and 74 by open surgery [OS]) was studied in three moments: before surgery (POD0) and on the 1st and 3th post-operative days (POD1 and POD3). RESULTS: Comparing to the laparoscopic group, in the OS group, C-reactive protein levels were significantly higher on POD1 and POD3 (p < 0.001), whereas lymphocyte levels were significantly lower (p = 0.006) and neutrophil levels were higher (p = 0.012) on POD1. On the other hand, higher levels of B cells (p = 0.023) were observed on POD1 in the laparoscopic group. Natural killer cell levels were significantly reduced (p = 0.034) in this group on POD3. CONCLUSIONS: Within the ERP, immune response pattern in both surgery approaches appears to be similar. Nevertheless, a greater inflammatory response of the OS is observed, whereas earlier recovery of the immune levels baseline seems to be a trend in the laparoscopic surgery.
INTRODUCCIÓN: El cáncer colorrectal es la segunda causa más frecuente de muerte por cáncer en todo el mundo. Los protocolos de recuperación mejorados (ERP) se desarrollaron en los años 90 para mejorar la recuperación de estos pacientes. Dentro de los ERP, este trabajo tiene como objetivo comparar la respuesta inmune entre procedimientos abiertos y laparoscópicos para respaldar el mejor abordaje quirúrgico. MATERIAL Y MÉTODOS: Se estudió el estado inmunológico de 148 pacientes sometidos a cirugía colorrectal (74 por vía laparoscópica y 74 por cirugía abierta) en tres momentos: antes de la cirugía (POD0) y en el 1 y 3 días postoperatorios (POD1 y POD3). RESULTADOS: En comparación con el grupo laparoscópico, en el grupo de cirugía abierta los niveles de proteína C reactiva fueron significativamente más altos en POD1 y POD3 (p < 0.001), mientras que los niveles de linfocitos fueron significativamente más bajos (p = 0.006) y los niveles de neutrófilos fueron más altos (p = 0.012) en POD1. Por otro lado, se observaron niveles más altos de células B (p = 0.023) en POD1 en el grupo laparoscópico. Los niveles de células asesinas naturales se redujeron significativamente (p = 0.034) en este grupo en POD3. CONCLUSIONES: Dentro del ERP, el patrón de respuesta inmune en ambos enfoques quirúrgicos parece ser similar. Sin embargo, se observa una mayor respuesta inflamatoria de la cirugía abierta, mientras que la recuperación más temprana de los niveles inmunitarios basales parece ser una tendencia en la cirugía laparoscópica.

BACKGROUND: The conversion to open surgery (COS) during the Laparoscopic Cholecystectomy (LC) is reported to occur at a rate of 10-15%. Some preoperative risk factors (RF) have been postulated; however, few studies have evaluated these factors and the intraoperative complexity with the COS rate. The aim of the study was to evaluate the preoperative RF and intraoperative complexity using the Parkland grading scale (PGS) with the COS rate in LC. METHODS: A retrospective study was done evaluating the demographic and surgical variables from the patients and LC videos from 8 different hospitals of Mexico City from December 2018 to January 2020. The evaluation of the PGS was done by 2 surgeons (one MI and one HPB surgeon); the PGS was also categorized as Non-Complex LC (nCLC, PGS1-2) and Complex LC (CLC, PGS 3-5). Logistic regression was used to evaluate the association of this factors with the COS rate. RESULTS: 430 LC were analyzed; 358 (78.61%) were women, 261 (60.7%) were elective and 169(39.3%) urgent LC, the mean age was 44.06 (SD ± 13.16) years. 21 (4.8%) LC were COS; the mean age of this group was 55 (SD ± 12.95), 3 (0.7%) were nCLC and 18 (4.19%) CLC, mean PGS of 3.76 (SD ± 1.09), the mean time to COS was 48.67 (SD ± 41.9), the estimated blood loss (EBL) was 258 (SD ± 260.22) and 6 (1.4%) intraoperative BDI were recognized on this group. Univariate analysis showed a significant association with the COS with male sex, older age, age > 45 years, presence of comorbidities, a higher PGS, a CLC, higher EBL and possible BDI; multivariate analysis produced a model using male sex, age, presence of comorbidities and a CLC with a 0.809 area under the ROC curve. CONCLUSION: The recognition of the associated RF and a CLC can guide the surgeon to establish preoperative and bailout strategies during the procedure, recognizing a higher risk of COS and its higher morbidity.

Objective: Few data about outcomes of elective infrarenal abdominal aortic aneurysm (AAA) repair in Latin America have been published. The objective of the present study is to address this aspect in our population. Method: Retrospective cohort, in which patients with infrarenal AAA undergoing elective surgical or endovascular repair from January 2011 to May 2017 at a university hospital in Autonomous City of Buenos Aires were consecutively included. The primary endpoints were perioperative mortality and all-cause mortality during follow-up. Among the secondary endpoints, the requeriment of reinterventions was assessed. Results: 195 patients were included. Open surgery was performed in 72 patients (36.9%) and endovascular aortic repair (EVAR) in 123 (63.1%). Perioperative mortality in the surgery group was 2.8%, while no deaths were recorded in the endovascular group (p = 0.06). The median follow-up was 38 months. No statistically significant difference was found in long-term mortality incidence rate between patients who underwent EVAR and those who underwent open surgery (7% per year vs. 6.7% per year, p = 0.8). The requirement of reinterventions was significantly higher in the endovascular group (9.0% vs. 0%, p = 0.01). Conclusions: Survival analyses demonstrated no statistically significant differences in perioperative and long-term mortality for patients who underwent EVAR compared with those who underwent open surgery, while the former had a higher rate of reinterventions. The results observed in our population do not differ from those published in the United State or Europe.
Ojetivo: La evidencia surgida en Latinoamérica acerca de los resultados de la reparación electiva del aneurisma de aorta abdominal (AAA) es escasa, por lo que el objetivo de este estudio es abordar este aspecto en la población nacional. Método: Cohorte retrospectiva en la cual se incluyó de forma consecutiva a pacientes con AAA infrarrenal sometidos a reparación quirúrgica o endovascular en forma electiva desde enero de 2011 hasta mayo de 2017 en un hospital universitario de la Ciudad Autónoma de Buenos Aires. Los puntos finales primarios fueron la mortalidad perioperatoria y la mortalidad por todas las causas durante el seguimiento. Entre los puntos finales secundarios se evaluó el requerimiento de reintervenciones. Resultados: Se incluyó a 195 pacientes. La operación abierta se llevó a cabo en 72 pacientes (36.9%), mientras que el procedimiento endovascular se practicó en 123 (63.1%). La mortalidad perioperatoria en el grupo quirúrgico fue de 2.8%, sin registro de muertes en el grupo endovascular (p = 0.06). La mediana de seguimiento fue de 38 meses. La incidencia de mortalidad tardía fue de 7%/año en pacientes con reparación endovascular y de 6.7%/año en los quirúrgicos (p = 0.8). El requerimiento de reintervenciones fue significativamente mayor en el grupo endovascular (9.0% vs. 0%, p = 0.01). Conclusiones: La mortalidad perioperatoria y la mortalidad tardía de los pacientes tratados de manera electiva por AAA en forma quirúrgica o endovascular fueron similares, en tanto que los pacientes sometidos a reparación endovascular requirieron mayor cantidad de reintervenciones. Los resultados observados en la población no difieren de los publicados en Estados Unidos o Europa.

BACKGROUND: Open surgical repair (OSR) and endovascular aneurysm repair (EVAR) surgery are alternative treatments for infrarenal abdominal aortic aneurysm (IRAAA). OBJECTIVES: To compare OSR and EVAR for the treatment of IRAAA. METHODS: 119 patients with IRAAA were electively operated by the same surgeon between January 1, 2006 and December 31, 2015, following selection for OSR or EVAR according to surgical risk. Complications, reinterventions, failures, and early and late mortality were analyzed. RESULTS: 63 OSR and 56 EVAR patients were analyzed. They were similar in terms of age (70 years), gender (92% men), and average diameter of IRAAA (6.5 cm), but with different comorbidities, surgical risk, and anatomy. EVAR was better than OSR regarding time in the operating theatre (177.5 vs. 233.3 minutes), need for transfusion (25 vs. 73%), and length of stay in ICU (1.3 vs. 3.3 days) and hospital (8.1 vs. 11.1 days). OSR allowed more associated procedures to be conducted simultaneously (19.0 vs. 1.8%). There were no significant differences between the groups with respect to complications (25.4 vs. 25.1%), reinterventions (3.2 vs. 5.2%), or early mortality (1.6 vs. 0%). During follow-up, OSR was associated with fewer revisions (3.13 vs. 4.21), angio-CTs (0.22 vs. 3.23), complications (6.4 vs. 37.5%), reinterventions (3.2 vs. 23.2%), and failures (1.6 vs. 10.7%), and had better survival (78.2 vs. 63.2%). CONCLUSIONS: Correct selection of patients achieves excellent results because it avoids OSR in patients at high risk and avoids EVAR in patients with high anatomical complexity, achieving similar results in the perioperative period, but better results for OSR over the course of follow-up.
CONTEXTO: A cirurgia aberta (CA) e o reparo endovascular de aneurisma (REVA) são tratamentos alternativos para o aneurisma da aorta abdominal infrarrenal (AAAIR). OBJETIVOS: Comparar CA e REVA no tratamento do AAAIR. MÉTODOS: Foram incluídos 119 pacientes com AAAIR, operados eletivamente pelo mesmo cirurgião entre 1 de janeiro de 2006 e 31 de dezembro de 2015, após seleção para CA ou REVA de acordo com o risco cirúrgico. Complicações, reintervenções, falhas e mortalidade precoce e tardia foram analisadas. RESULTADOS: Foram analisados 63 pacientes de CA e 56 de REVA, com semelhanças de idade (70 anos), sexo (92% homens) e diâmetro médio do AAAIR (6,5 cm), mas com diferentes comorbidades, riscos cirúrgicos e anatomias. O REVA foi melhor que a CA em relação ao tempo na sala de cirurgia (177,5 vs. 233,3 minutos), necessidade de transfusão (25 vs. 73%) e tempo de permanência na unidade de terapia intensiva (1,3 vs. 3,3 dias) e no hospital (8,1 vs. 11,1 dias). A CA permitiu que mais procedimentos associados fossem realizados simultaneamente (19,0 vs. 1,8%). Não houve diferenças significativas entre os grupos em relação a complicações (25,4 vs. 25,1%), reintervenções (3,2 vs. 5,2%) e mortalidade precoce (1,6 vs. 0%). Durante o acompanhamento, a CA apresentou menos revisões (3,13 vs. 4,21), angiotomografias (0,22 vs. 3,23), complicações (6,4 vs. 37,5%), reintervenções (3,2 vs. 23,2%) e falhas (1,6 vs. 10,7%), além de ter melhor sobrevida (78,2 vs. 63,2%). CONCLUSÕES: A seleção correta dos pacientes proporciona excelentes resultados porque evita pacientes com alto risco para CA e com complexidade anatômica para REVA. Os resultados são semelhantes no período perioperatório, mas melhores para CA durante o acompanhamento.
RESUMO
BACKGROUND: In 2014, A Randomized Trial of Unruptured Brain Arteriovenous Malformations (ARUBA) concluded that medical management alone for cranial arteriovenous malformations (AVMs) had better clinical outcomes than interventional treatment. The impact of the ARUBA study on changes in the rates of intervention and outcomes is unknown. Thus, we investigated whether the conclusions from ARUBA may have influenced treatment modalities and outcomes of unruptured AVMs. METHODS: The National Inpatient Sample (NIS) was queried between 2006 and 2018, for adult patients with an AVM who were admitted on an elective basis. Interventions included open, endovascular, and stereotactic surgeries. Join-point regression was used to assess differences in slopes of treatment rate for each modality before and after the time-point. Logistic regression was used to assess the odds of non-routine discharge and hemorrhage between the two time-points for each treatment modality. Linear regression was used to assess the mean length of stay (LOS) for each treatment modality between the two time-points. RESULTS: A total of 40,285 elective admissions for AVMs were identified between 2006 and 2018. The rate of intervention was higher pre-ARUBA (n = 15,848; 63.8%) compared to post-ARUBA (n = 6985; 45.2%; difference in slope - 8.24%, p < 0.001). The rate of open surgery decreased, while endovascular and stereotactic surgeries remained the same, after the ARUBA trial time-point (difference in slopes - 8.24%, p < 0.001; - 1.74%, p = 0.055; 0.20%, p = 0.22, respectively). For admissions involving interventions, the odds of non-routine discharge were higher post-ARUBA (OR 1.24; p = 0.043); the odds of hemorrhage were lower post-ARUBA (OR 0.69; p = 0.025). There was no statistical difference in length of stay between the two time-points (p = 0.22). CONCLUSION: The rate of intervention decreased, the rate of non-routine discharge increased, and rate of hemorrhage decreased post-ARUBA, suggesting that it may have influenced treatment practices for unruptured AVMs.

INTRODUCTION AND IMPORTANCE: An incisional hernia is one of the most frequent complications after abdominal surgery, with an estimated incidence of 2-20% after midline laparotomy. They are often caused by poor wound healing. We present the case of a complex giant incisional hernia that was repaired by implanting an intraperitoneal mesh. CASE PRESENTATION: A 63-year-old man with obesity, hypertension, and multiple previous laparotomies, who developed a complex giant incisional hernia (xipho-pubic > 10 cm wide). An open technique repair was decided with the introduction of a large mesh (Parietex ™ Composite) in an intraperitoneal position, covering a 25 × 16 cm hernial ring. After two years, the patient continues to be followed due to a low-output distal enterocutaneous fistula. CLINICAL DISCUSSION: Currently, there is no technique or approach that has become a gold standard for ventral incisional hernia repair. The introduction of an intraperitoneal mesh with two surfaces by laparotomy is recommended when there are contraindications for laparoscopic surgery, for example in obese patients, and patients with multiple previous laparotomies. However, it has been reported to be a complex technique with an enterocutaneous fistula rate of 0.3-4%. CONCLUSION: The introduction of a composite mesh represents an alternative surgical technique for the repair of giant incisional hernias.
RESUMO
ABSTRACT Objective: In Brazil, there are no studies comparing endoscopic treatment of lumbar disc herniation with the conventional open technique in SUS (Unified Health System) with regard to hospitalization time and complications occurring within one year, which is the objective of this study. Methods: A survey of 32 surgeries performed in 2019 (11 open and 21 endoscopic) to evaluate pain parameters before and after surgery (VAS), days of hospitalization, and complications. The data were submitted to statistical analysis (ANOVA) using the Kruskal-Wallis test. Results: Fourteen patients were female and eighteen were male, with a mean age of 41.35 years (p> 0.05 between sexes). The pre- and postoperative VAS for pain radiating to the lower limb were similar between the groups: 8.5 ± 0.82 with the open technique and 8.19 ± 1.15 with endoscopic technique. In both groups there was an improvement in the pain pattern with a significant reduction in the VAS (p < 0.05) and there was no statistical relevance between the groups in terms of pain improvement. There was statistical relevance between the groups in the comparison of days of hospitalization required, with the group submitted to endoscopic surgery having a lower number of days. The complications reported were compatible with those found in the literature (postoperative dysesthesia, new herniation). Conclusions: The endoscopic technique resulted in an important reduction in the number of days of hospitalization, a factor with a high impact on the costs of any surgical procedure, which can be a determining factor in the feasibility of minimally invasive techniques. Level of evidence IV; Therapeutic Study.
RESUMO Objetivos: No Brasil, não há estudos que comparem o tratamento endoscópico de hérnia de disco lombar no SUS (Sistema Único de Saúde) com a técnica aberta convencional, no que diz respeito aos resultados com relação ao tempo de internação e complicações ocorridas em um ano, o que vem a ser o objetivo deste estudo. Métodos: Levantamento de 32 cirurgias realizadas em 2019 (11 por via aberta e 21 por via endoscópica) para avaliar os parâmetros de dor antes e depois da cirurgia (EVA), dias de internação e complicações. Os dados foram submetidos à análise estatística (ANOVA) com o teste de Kruskal-Wallis. Resultados: Catorze pacientes eram do sexo feminino e 18 do sexo masculino, com média de idade de 41,35 anos (p > 0,05 para os dois sexos). A EVA de dor irradiada para o membro inferior no pré e pós-operatório foi semelhante entre os grupos: 8,5 ± 0,82 com a técnica aberta e 8,19 ± 1,15 com a técnica endoscópica. Em ambos os grupos houve melhora do padrão de dor com redução significativa da EVA (p < 0,05) e não houve relevância estatística entre os grupos quanto à melhora do dor. Na comparação das diárias de internação necessárias houve relevância estatística entre os grupos, sendo que o grupo submetido à endoscopia teve número menor de diárias. As complicações relatadas são compatíveis com as encontradas na literatura (disestesia pós-operatória, nova herniação). Conclusões: A técnica endoscópica resultou em redução importante do número de dias de internação, fator com alto impacto nos custos de qualquer procedimento cirúrgico, que pode ser determinante para viabilizar técnicas minimamente invasivas. Nível de evidência IV; Estudo Terapêutico.
