Risk factors for PPCs in laparoscopic non-robotic vs. laparoscopic robotic abdominal surgery (LapRas): rationale and protocol for a patient-level analysis of LAS VEGAS and AVATaR.

INTRODUCTION: Postoperative pulmonary complications (PPCs) vary amongst different surgical techniques. We aim to compare the incidence of PPCs after laparoscopic non-robotic versus laparoscopic robotic abdominal surgery. METHODS AND ANALYSIS: LapRas (Risk Factors for PPCs in Laparoscopic Non-robotic vs Laparoscopic robotic abdominal surgery) incorporates harmonized data from 2 observational studies on abdominal surgery patients and PPCs: 'Local ASsessment of VEntilatory management during General Anaesthesia for Surgery' (LAS VEGAS), and 'Assessment of Ventilation during general AnesThesia for Robotic surgery' (AVATaR). The primary endpoint is the occurrence of one or more PPCs in the first five postoperative days. Secondary endpoints include the occurrence of each individual PPC, hospital length of stay and in-hospital mortality. Logistic regression models will be used to identify risk factors for PPCs in laparoscopic non-robotic versus laparoscopic robotic abdominal surgery. We will investigate whether differences in the occurrence of PPCs between the two groups are driven by differences in duration of anesthesia and/or the intensity of mechanical ventilation. ETHICS AND DISSEMINATION: This analysis will address a clinically relevant research question comparing laparoscopic and robotic assisted surgery. No additional ethical committee approval is required for this metanalysis. Data will be shared with the scientific community by abstracts and original articles submitted to peer-reviewed journals. REGISTRATION: The registration of this post-hoc analysis is pending; individual studies that were merged into the used database were registered at clinicaltrials.gov: LAS VEGAS with identifier NCT01601223, AVATaR with identifier NCT02989415.

Erector spinae plane block as a rescue therapy in following cholecystectomy: a historical cohort study.

OBJECTIVE: The aim of this study is to evaluate the effect of erector spinae plane block (ESPB) as a rescue therapy in the recovery room. MATERIALS AND METHODS: This single-center historical cohort study included patients who received either ESPB or intravenous meperidine for pain management in the recovery room. Patients' numeric rating scale (NRS) scores and opoid consumptions were evaluated. RESULTS: One hundred and eight patients were included in the statistical analysis. Sixty-two (57%) patients received ESPB postoperatively (pESPB) and 46 (43%) patients were managed with IV meperidine boluses only (IV). The cumulative meperidine doses administered were 0 (0-40) and 30 (10-80) mg for the pESPB and IV groups, respectively (p < 0.001). NRS scores of group pESPB were significantly lower than those of Group IV on T30 and T60. CONCLUSION: ESPB reduces the frequency of opioid administration and the amount of opioids administered in the early post-operative period. When post-operative rescue therapy is required, it should be considered before opioids.

OBJETIVO: Evaluar el efecto del bloqueo del plano erector espinal (ESPB) como terapia de rescate en la sala de recuperación. MÉTODO: Este estudio de cohortes histórico de un solo centro incluyó a pacientes que recibieron ESPB o meperidina intravenosa para el tratamiento del dolor en la sala de recuperación. Se evaluaron las puntuaciones de la escala de calificación numérica (NRS) de los pacientes y los consumos de opiáceos. RESULTADOS: En el análisis estadístico se incluyeron 108 pacientes. Recibieron ESPB 62 (57%) pacientes y los otros 46 (43%) fueron manejados solo con bolos de meperidina intravenosa. Las dosis acumuladas de meperidina administradas fueron 0 (0-40) y 30 (10-80) mg para los grupos de ESPB y de meperidina sola, respectivamente (p < 0.001). Las puntuaciones de dolor del grupo ESPB fueron significativamente más bajas que las del grupo de meperidina sola en T30 y T60. CONCLUSIONES: El ESPB reduce la frecuencia de administración de opiáceos y la cantidad de estos administrada en el posoperatorio temprano. Cuando se requiera terapia de rescate posoperatoria, se debe considerar antes que los opiáceos.

RESULTADOS: El componente más importante del disector es la punta que tiene contacto con los tejidos: es una tela de algodón-poliéster negra impregnada en un gel (patentado) que, al ser sumergido en un termo con solución salina caliente, permite retener la temperatura. CONCLUSIONES: Este dispositivo ha sido utilizado en 364 procedimientos quirúrgicos por vía laparoscópica y ha demostrado ser útil para visualizar, separar y limpiar estructuras anatómicas sin producir daño por lesión térmica, desgarre, hemorragia ni perforación visceral.

Comparison of laparoscopic-guided versus ultrasound-guided TAP block in laparoscopic cholecystectomy.

INTRODUCTION: Transversus abdominis plane (TAP) block is a widely used anesthetic technique of the abdominal wall, where ultrasound guidance is considered the gold standard. In this study, we aimed to compare the effectiveness of laparoscopic-assisted TAP (LTAP) block with ultrasound-assisted TAP (UTAP) block for post-operative pain, nausea, vomiting, duration of the block, and bowel function. MATERIALS AND METHODS: This study included 60 patients who were randomly assigned to two groups to undergo either the LTAP or UTAP block technique after laparoscopic cholecystectomy. The time taken for administering the block, post-operative nausea and vomiting, post-operative pain, respiratory rate, bowel movements, and analgesia requirements were reported. RESULTS: The time taken for the LTAP block was shorter (p < 0.001). Post-operative mean tramadol consumption, paracetamol consumption, and analgesic requirement were comparable between the two groups (p = 0.76, p = 0.513, and p = 0.26, respectively). The visual analog scale at 6, 24, and 48 h was statistically not significant (p = 0.632, p = 0.802, and p = 0.173, respectively). Nausea with vomiting and the necessity of an antiemetic medication was lower in the UTAP group (p = 0.004 and p = 0.009, respectively). CONCLUSION: The LTAP block is an easy and fast technique to perform in patients as an alternative method where ultrasound guidance or an anesthesiologist is not available.

ANTECEDENTES: El bloqueo del plano transverso del abdomen (TAP) es una técnica anestésica de la pared abdominal ampliamente utilizada, en la cual la guía ecográfica se considera el método de referencia. OBJETIVO: Comparar la efectividad del bloqueo TAP asistido por laparoscopia (LTAP) con el bloqueo TAP asistido por ultrasonido (UTAP) para el dolor posoperatorio, las náuseas y los vómitos, y la función intestinal. MÉTODO: El estudio incluyó 60 pacientes que fueron asignados aleatoriamente a dos grupos para someterse a la técnica de bloqueo LTAP o UTAP después de una colecistectomía laparoscópica. Se informaron el tiempo de administración del bloqueo, las náuseas y los vómitos posoperatorios, el dolor posoperatorio, la frecuencia respiratoria, las evacuaciones y los requerimientos de analgesia. RESULTADOS: El tiempo de bloqueo LTAP fue menor (p < 0.001). El consumo medio de tramadol, el consumo de paracetamol y el requerimiento de analgésicos posoperatorios fueron comparables entre los dos grupos (p = 0.76, p = 0.513 y p = 0.26, respectivamente). El dolor en la escala analógica visual a las 6, 24 y 48 horas no fue estadísticamente significativo (p = 0.632, p = 0.802 y p = 0.173, respectivamente). CONCLUSIONES: El bloqueo PATL es una técnica fácil y rápida de realizar en pacientes como método alternativo cuando no se dispone de guía ecográfica o anestesióloga.

The evolution of the treatment of esophageal achalasia. Chronicle of a 35-year journey.

Over the last few decades, significant improvement has been made in both the evaluation and treatment of esophageal achalasia. The Chicago classification, today in version 4.0, is now the standard for diagnosis of achalasia, providing a classification into 3 subtypes with important therapeutic and prognostic implications. Therapy, which was at first mostly limited to pneumatic dilatation, today includes minimally invasive surgery and peroral endoscopic myotomy, allowing for a more tailored approach to patients and better treatment of recurrent symptoms. This review chronicles my personal experience with achalasia over the last 35 years, describing the progress made in the treatment of patients with achalasia.

Histerectomía laparoscópica en patología benigna en un hospital universitario terciario. Análisis y evolución de un periodo de 8 años / Laparoscopic hysterectomy for benign pathology in a tertiary university hospital: Analysis and evolution in a period of 8 years

Objetivo: Reflexionar desde el análisis de los datos del número de histerectomías laparoscópicas que puede realizar cada miembro de un servicio de ginecología de un hospital terciario sobre la conveniencia de limitar este procedimiento a un número limitado de profesionales. Material y métodos: Estudio retrospectivo, descriptivo, sobre las histerectomías realizadas por cualquier indicación en nuestro hospital en el periodo comprendido entre el 1 de mayo del año 2014 y el 30 de abril del año 2022. Resultados: En este periodo hemos realizado 1548 histerectomías, de las que 760 se efectuaron por vía laparoscópica; y de ellas, 289 fueron indicadas por patología benigna. Considerando el total de profesionales que conforman el pool de cirujanos que realizan cirugía por patología benigna, la media de histerectomías laparoscópicas por cirujano y año sería de 1,4 casos. Conclusiones: Para garantizar la adecuada calidad de la cirugía, el número de profesionales que realizan histerectomías laparoscópicas en un hospital terciario debe ser limitado.(AU)

Objective: To reflect from the analysis of the data of the number of laparoscopic hysterectomies that each member of a gynaecology service of a tertiary hospital can perform on the convenience of limiting this procedure to a limited number of professionals. Material and methods: Retrospective, descriptive study on hysterectomies performed for any indication in our hospital in the period between May 1, 2014 and April 30, 2022. Results: In this period, we have performed 1548 hysterectomies of which 760 were performed laparoscopically and of these, 289 were indicated for benign pathology. Considering the total number of professionals that make up the pool of surgeons who perform surgery for benign pathology, the average number of laparoscopic hysterectomies per surgeon per year would be 1.4 cases. Conclusions: To ensure adequate quality of surgery, the number of professionals performing laparoscopic hysterectomies in a tertiary hospital should be limited.(AU)

Pre-incisional local infiltration with levobupivacaine in laparoscopic cholecystectomy: a randomized and clinical trial.

OBJECTIVE: Laparoscopic cholecystectomy (LC), despite its minimally invasive nature, requires effective control of post-operative pain. The use of local anesthetics (LA) has been studied, but the level of evidence is low, and there is little information on important parameters such as health-related quality of life (HRQoL) or return to work. The objective of the study was to evaluate the efficacy of 0.50% levobupivacaine infiltration of incisional sites in reducing POP after LC. METHODS: This was a prospective, randomized, double-blind study. Patients undergoing elective LC were randomized into two groups: no infiltration (control group) and port infiltration (intervention group). POP intensity (numerical rating scale, NRS), need for rescue with opioid drugs, PONV incidence, HRQoL, and return to work data, among others, were studied. RESULTS: Two hundred and twelve patients were randomized and analyzed: 105 (control group) and 107 (intervention group). A significant difference was observed in the NRS values (control group mean NRS score: 3.41 ± 1.82 vs. 2.56 ± 1.96) (p < 0.05) and in the incidence of PONV (31.4% vs. 19.6%) (p = 0.049). CONCLUSIONS: Levobupivacaine infiltration is safe and effective in reducing POP, although this does not lead to a shorter hospital stay and does not influence HRQoL, return to work, or overall patient satisfaction.

OBJETIVO: la colecistectomía laparoscópica (CL), a pesar de su carácter mínimamente invasivo, requiere un control efectivo del dolor postoperatorio (POP). El uso de anestésicos locales (AL) ha sido estudiado pero el nivel de evidencia es bajo y existe poca información acerca de parámetros relevantes como la calidad de vida relacionada con la salud (CVRS) o la reincorporación laboral. El objetivo de este estudio es analizar la eficacia de la infiltración de los sitios incisionales con levobupivacaína 0,50% en la reducción del dolor postoperatorio tras la CL. MATERIAL Y MÉTODOS: estudio prospectivo, aleatorizado y doble ciego. Pacientes sometidos a CL programada fueron aleatorizados en dos grupos: sin infiltración (grupo control) y con infiltración preincisional (grupo intervención). La intensidad del dolor (escala de puntuación numérica, NRS), la necesidad de rescates con opioides, la incidencia de náuseas o vómitos postoperatorios (NVPO) y datos de CVRS o reincorporación laboral, entre otros, fueron recogidos. RESULTADOS: 212 pacientes fueron aleatorizados y analizados: 105 en el grupo control y 107 en el grupo de intervención. Se observó una diferencia estadísticamente significativa en la intensidad del dolor (puntuación media NRS: 3.41 ± 1.82 vs. 2.56 ± 1.96) (p < 0.05) y en la incidencia de NVPO (31.4% vs. 19.6%) (p = 0.049). CONCLUSIONES: La infiltración con levobupivacaína es segura y efectiva en la reducción del dolor postoperatorio, aunque esto no conlleva una menor estancia hospitalaria y no influye en los resultados de CVRS, reincorporación laboral o satisfacción del paciente.

Results during the learning curve in the laparoscopic common bile duct exploration for choledocolithiasis.

OBJECTIVES: To analyze the results obtained in terms of efficacy and safety during the learning curve of a surgical team in the technique of laparoscopic common bile duct exploration with cholecystectomy (LCBDE+LC) using choledochoscopy for the treatment of patients with cholelithiasis and choledocolithiasis or common bile duct stones (CBDS) (CDL). METHODS: Single-center prospective analysis of patients treated with LCBDE+LC during the first 4 years of implementation of the technique. A descriptive and comparative analysis was carried out between groups according to the transcystic (TCi) or transcolecocal (TCo) approach, and also evolutionary by periods. The effectiveness of the technique was evaluated using the variable success rate and safety through the analysis of the overall complication rate and the bile leak rate as the most frequent adverse effect. RESULTS: A total of 78 patients were analyzed. The most frequent approach was TCo (62%). The overall success rate was 92%. The TCi group had a shorter operating time, a lower overall complications rate and a shorter hospital stay. The TCo approach was related to a higher rate of clinically relevant bile leak (8%). Complex cases increased significantly during the learning curve without effect on the overall results. CONCLUSIONS: LCBDE+LC is an effective and safe technique during the learning curve. Its results are comparable to those published by more experienced groups and do not present significant differences related to the evolution during learning period.

Comparación de los resultados oncológicos entre cirugía radical por laparotomía versus la de mínima invasión en cáncer temprano de cérvix / Comparison of oncologic outcomes between radical laparotomy surgery versus minimally invasive surgery for early cervical cancer

Introducción: la histerectomía radical con linfadenectomía pélvica es el tratamiento estándar para las pacientes con cáncer de cérvix en estadios tempranos que no desean preservar la fertilidad. Objetivos: comparar tasas de supervivencia global, periodo libre de enfermedad y recurrencia entre histerectomía radical por mínima invasión (CMI) versus cirugía abierta. Además analizar las características histopatológicas, complicaciones intraoperatorias, posoperatorias tempranas y tardías entre ambas técnicas. Metodología: estudio observacional de cohorte retrospectivo entre 2011 y 2017. Se incluyeron mayores de 18 años con diagnóstico de carcinoma de cuello uterino en estadios IA1 (invasión del espacio linfovascular) a IB1 (FIGO 2009) con seguimiento hasta diciembre 2020. Se hizo análisis bivariado utilizando chi cuadrado, prueba exacta de Fisher o U Mann Whitney para determinar las diferencias entre las técnicas quirúrgicas frente a características sociodemográficas, clínicas, complicaciones intraoperatorias, tempranas y tardías. Se calcularon tasas de supervivencia global y densidades de recurrencia con el tiempo aportado por las pacientes. Resultados: de 113 pacientes llevadas a histerectomía radical, 75 se excluyeron del análisis. La supervivencia global fue 100% para las del grupo de laparotomía versus 97.6% en CMI. La tasa de recurrencia global fue de 8 casos y la del grupo de CMI 14.1 por 1.000 personas/año de observación. El grupo de laparotomía no presentó recaídas. Hubo diferencia significativa en la mediana de sangrado intraoperatorio (600 cc laparotomía versus 100 cc laparoscopia, p= 0.002); 11.4% requirieron transfusión intraoperatoria (25% laparotomía versus 2.4% mínima invasión, p=0,006). Conclusiones: las pacientes llevadas a cirugía por laparoscopia tuvieron una mayor proporción de recurrencia y mortalidad en comparación con el abordaje por técnica abierta.

Introduction: radical hysterectomy with pelvic lymphadenectomy is the standard treatment for early cervical cancer patients who do not wish to preserve fertility. Objetives: this study compares overall survival, disease-free survival, and recurrence rates of patients undergoing minimally invasive radical hysterectomy (MIS) versus open surgery. Likewise, the histopathological characteristics, intraoperative complications, early and late postoperative complications, are analyzed for both techniques, Methodology: an observational retrospective cohort study between 2011 and 2017. Patients over 18 years of age diagnosed with cervical carcinoma in stages IA1 (lymph vascular space invasion) and IB1 (FIGO 2009) receiving follow-up care until December 2020, were included. The Chi-square test, Fisher ́s exact test or Mann Whitney U test were used for bivariate analysis, to determine the differences between the techniques with regards to sociodemographic, clinical characteristics and intraoperative early and late complications. Overall survival rates and recurrence densities were calculated with data provided by the patients. Results: of the 113 patients undergoing radical hysterectomy, 75 were excluded from the analysis. Overall survival was 100% in the laparotomy group versus 97.6% in the MIS group. The overall recurrence rate was of 8 cases, 14.1 per 1.000 person-years of observation in the MIS group. Patients in the laparotomy group developed no recurrences. There was a significant difference in median intraoperative blood loss (600 cc in laparotomy versus 100 cc in laparoscopy, p= 0.002); 11.4% of patients required intraoperative transfusion (25% in the laparotomy group versus 2.4% in the MIS group, p=0.006). Conclusions: patients who underwent laparoscopic surgery had a higher recurrence and mortality rate than that of open approach

Lidocaína en infusión transoperatoria para control de dolor: un estudio aleatorizado / Intraoperative intravenous lidocaine pain control: a randomized study

Resumen: Introducción: contar con una analgesia efectiva en el postoperatorio es fundamental para evitar complicaciones asociadas a dolor, en pacientes sometidos a colecistectomía laparoscópica. Objetivos: evaluar la efectividad de la lidocaína en infusión transoperatoria para el control de dolor postoperatorio en pacientes sometidos a colecistectomía laparoscópica. Material y métodos: se realizó un estudio experimental, aleatorizado, ciego simple, en pacientes sometidos a colecistectomía laparoscópica en el Hospital General Regional No. 1 en Obregón. Se dividieron en dos grupos de forma aleatoria, al grupo L se le aplicó lidocaína 1.5 mg/k en infusión, al grupo P se le aplicó placebo. Se realizó un análisis estadístico en SPSS v. 22 y se consideró significativa una p < 0.05. Resultados: se observó un adecuado manejo del dolor en los pacientes del grupo L a su ingreso a la Unidad de Recuperación Postanestésica (URPA) (p = 0.002), menor consumo de fentanyl transoperatorio sin diferencia estadística contra placebo (p = 0.086), menor uso de analgesia de rescate postquirúrgica (p = 0.045). Conclusiones: la infusión de lidocaína es efectiva para el manejo del dolor postquirúrgico inmediato, así como disminución de consumo de opioides y dosis de rescate analgésico, con una baja incidencia de náuseas y vómito, pero se asoció a hipotensión transoperatoria.

Abstract: Introduction: having an effective analgesia in the postoperative period is essential to avoid complications associated with pain in patients undergoing laparoscopic cholecystectomy. Objectives: test the effectiveness of intravenous lidocaine for postoperative pain in cholecystectomized patients by laparoscopy. Material and methods: an experimental, randomized, single-blind study was carried out in patients who underwent laparoscopic cholecystectomy at the No. 1 Regional General Hospital in Obregon, Sonora. They were divided into two groups randomly: group L to whom we applied lidocaine 1.5 mg/k in infusion and group P to whom placebo was applied. A statistical analysis was performed in SPSS v. 22 and a p < 0.05 was considered significant. Results: adequate pain management was observed in patients of group L upon admission to PACU (p = 0.002), lower consumption of transoperative fentanyl without statistical difference against placebo (p = 0.086), lower use of post-surgical rescue analgesia (p = 0.045), but higher incidence of adverse effects such as hypotension and bradycardia (p = 0.024). Conclusions: the infusion of lidocaine is effective for the management of immediate postsurgical pain; as well it decreases opioid consumption and analgesic rescue dose, with a low incidence of nausea and vomiting, but associated with hypotension after surgery.

Gallbladder stones during pregnancy: are we doing the right thing in Mexico?

OBJECTIVE: To present the treatment of choice and approach in pregnant and postpartum women with a diagnosis of gallstones in Mexico and to compare it with the recommendations of international guidelines. METHOD: Observational, descriptive, and retrospective study based on information from the 2019 Dynamic Cubes database of pregnant women diagnosed with cholecystitis and/or cholelithiasis who had undergone cholecystectomy. RESULTS: During 2019, 937 patients with cholelithiasis and cholecystitis were registered, 516 (55%) pregnant and 421 (45%) in puerperium. 91.47% of cases were managed with medical treatment and 8.53% with cholecystectomy, with predominance in the open approach in 63.75% of cases. Mortality was nil in both groups. CONCLUSIONS: Despite current international guidelines recommending early laparoscopic cholecystectomy in pregnant or puerperal women, in Mexico medical treatment, delayed cholecystectomy and its open approach are still privileged.

OBJETIVO: Determinar el tratamiento de elección, el abordaje y la mortalidad en mujeres embarazadas y en puerperio con diagnóstico de litiasis vesicular en México, y compararlo con las recomendaciones de las guías internacionales. MÉTODO: Estudio observacional, descriptivo y retrospectivo basado en la información de la base de datos Cubos Dinámicos del año 2019 de mujeres embarazadas con diagnóstico de colecistitis o colelitiasis que se hubieran realizado colecistectomía. RESULTADOS: En 2019 se registraron 937 pacientes con colelitiasis y colecistitis, 516 (55%) embarazadas y 421 (45%) en puerperio. El 91.47% de los casos se manejaron con tratamiento médico y el 8.53% con colecistectomía, con predominio del abordaje abierto en el 63.75% de los casos. La mortalidad fue nula en ambos grupos. CONCLUSIONES: A pesar de que las guías internacionales actuales recomiendan la colecistectomía laparoscópica temprana en embarazadas y puérperas, en México todavía se privilegian el tratamiento médico, el retraso de la colecistectomía y su abordaje abierto.

Is laparoscopic TAPP the preferred approach for the treatment of inguinal hernia? Technique, indications and future perspectives.

The repair of inguinal hernia is one of the most frequently performed surgeries in General Surgery units. The laparoscopic approach for these hernias will be clearly considered as the gold standard, based on its advantages over the open approach. There are no clear advantages of the transabdominal preperitoneal approach (TAPP) over the totally preperitoneal approach (TEP), although it has been shown to be more reproducible, presenting a shorter learning curve, although it presents more possibilities of developing trocar site hernias. Laparoscopic TAPP could be superior to TEP in the following indications: incarcerated hernias, emergencies, previous preperitoneal surgery, previous Pfanestiel-type incision, recurrent hernias, inguinoscrotal hernias and obese, being also a better alternative for females. Robotic TAPP is a safe approach with similar results to laparoscopy; however, it is related to an increase in costs and operating time. The value of this technology for the repair of complex hernias (multiple recurrences, inguino-scrotal or after previous preperitoneal surgery) remains to be determined, since they represent a certain challenge for the conventional laparoscopic approach. On the other hand, robotic repair of inguinal hernias may be a way to reduce the learning curve before addressing complex ventral hernias. Finally, artificial intelligence applied to the laparoscopic approach to inguinal hernia will undoubtedly have a significant impact in the future especially to determine the best the indications for this approach, on the performance of a safer technique, on the correct selection of meshes and fixation mechanisms, and on learning curve.

Cáncer incidental de vesícula biliar tras Colecistectomía Laparoscópica / Incidental gallbladder cancer after Laparoscopy Cholecystectomy

El carcinoma de vesícula biliar es una entidad poco frecuente. El diagnóstico precoz de esta neoplasia es difícil, ya que sus síntomas son muy inespecíficos y muchas veces estes se realiza de manera tardía cuando el enfermo posee una enfermedad avanzada y solo para mitigar los síntomas. Con el crecimiento exponencial en el número de colecistectomías laparoscópicas en las últimas décadas, se ha generado un aumento en la detección de neoplasias incidentales, permitiendo ofrecer tratamiento curativo en un gran grupo de pacientes. Se evaluaron todas las colecistectomías realizadas durante julio de 2019 a diciembre de 2022 en el Hospital Nacional de Clínicas, Córdoba, Argentina. La evaluación patológica de todas las muestras quirúrgicas reveló una incidencia de 0,83% de adenocarcinoma insospechado en colecistectomías realizadas. 66% de los pacientes con neoplasias insospechadas pertenecían al sexo femenino

Gallbladder carcinoma is a rare entity. Early diagnosis of this neoplasia is difficult, since its symptoms are very unspecific and often this is done late when the patient has an advanced disease and only to mitigate symptoms. With the exponential growth in the number of laparoscopic cholecystectomies in recent decades, there has been an increase in the detection of incidental neoplasms, allowing offering curative treatment in a large group of patients. All cholecystectomies performed during July 2019 to December 2022 were evaluated at the National Hospital of Clinics, Córdoba, Argentina. Pathological evaluation of all surgical samples revealed an incidence of 0.83% of unsuspected adenocarcinoma in cholecystectomies performed. 66% of patients with unsuspected neoplasms were female

La lesión quirúrgica de la vía biliar es una complicación peligrosa de la colecistectomía, con importantes secuelas postoperatorias para el paciente en términos de morbilidad, mortalidad y calidad de vida. Tienen una incidencia laparoscópica estimada del 0,4% al 1,5% y del 0,2% al 0,3% en la colecistectomía convencional. El objetivo de este estudio fue evaluar la incidencia de LQVB durante la formación del cirujano y la importancia de realizar colangiografía intraoperatoria (COI) durante esta etapa

Bile duct surgical injury is a dangerous complication of cholecystectomy, with significant postoperative sequelae for the patient in terms of morbidity, mortality and quality of life. These have an estimated laparoscopic incidence of 0.4% to 1.5% and 0.2% to 0.3% in conventional cholecystectomy. The aim of this study was to evaluate the incidence of LQVB during surgeon training and the importance of performing intraoperative cholangiography (IOC) during this stage

Resecciones hepáticas laparoscópicas: ¿qué hemos aprendido luego de más de 20 años de experiencia? / Laparoscopic liver resections: What have we learned after more than 20 years of experience?

Introducción: El objetivo de este estudio es describir nuestra experiencia en los últimos 8años de resecciones hepáticas laparoscópicas (RHL) por tumores benignos y malignos, para evaluar indicaciones y resultados, y comparar los resultados con nuestra experiencia previa y con otros centros de referencia a nivel mundial. Métodos: A partir de una base de datos prospectiva de la Unidad de Cirugía Hepatopancreatobiliar y Trasplante Hepático del Hospital Italiano de Buenos Aires se analizaron de forma retrospectiva los pacientes que fueron sometidos a RHL entre septiembre de 2014 y junio de 2022 (períodoB) y se compararon los resultados con nuestra propia experiencia de RHL realizadas entre los años 2000 y 2014, publicada previamente (períodoA). Resultados: La indicación quirúrgica más frecuente fue por metástasis de cáncer colorrectal (26,4%). El 15,7% de las resecciones fueron hepatectomías mayores y el procedimiento más frecuentemente realizado fueron hepatectomías típicas y atípicas (58,4%), seguido por la hepatectomía lateral izquierda (20,3%). La tasa de complicaciones mayores fue del 10,1%. La mortalidad en los primeros 90días postoperatorios fue del 1%. La mediana de estancia postoperatoria fue de 4 (IQR: 3-6) días. La sobrevida global al año, a los 3 y a los 5años fue del 94%, del 84% y del 70%, respectivamente, con una media de seguimiento de 22,9meses. Conclusiones: Las resecciones hepáticas por vía laparoscópica en manos de cirujanos entrenados continúan creciendo de manera segura, y hemos visto un aumento en la indicación de RHL para patologías malignas y resecciones mayores, tendencia que acompaña al resto de los grandes centros del mundo y se ha convertido en el método de elección para el tratamiento quirúrgico de la mayoría de los tumores hepáticos.

Introduction: The aim of this study is to describe our experience in the last 8years of laparoscopic liver resections (LLR) for benign and malignant tumors, to evaluate indications and results, and to compare the results with our previous experience and with other reference centers worldwide. Methods: Based on a prospective database of the Hepatopancreatobiliary Surgery and Liver Transplantation Unit of the Hospital Italiano de Buenos Aires, patients who underwent LLR between September 2014 and June 2022 were retrospectively analyzed (periodB) and where compared to our own experience from 2000-2014 previously published (periodA). Results: Colorectal liver metastasis was the main indication for surgery (26.4%). Major hepatectomies accounted for 15.7% of resections and the most frequently performed procedure was typical and atypical hepatectomies (58.4%) followed by left lateral hepatectomy (20.3%). The total postoperative major complications rate was 10.1% and the 90-day postoperative mortality was 1%. The median postoperative stay was four (IQR: 3-6) days. The overall survival rate estimated at 1, 3 and 5 years was 94%, 84% and 70%, respectively, with a median follow-up of 22.9months. Conclusions: LLRs in the hands of trained surgeons continue to grow safely, and we have seen an increase in the indication of LLR for malignant pathologies and major resections, a trend that follows the rest of the major centers in the world and has become the method of choice for surgical treatment of most liver tumors.

Colecistectomía laparoscópica urgente por colecistitis aguda litiásica en Pediatría / Urgent laparoscopic cholecystectomy as a result of acute calculous cholecystitis in pediatrics

Introducción: Pese al aumento en la prevalencia de colelitiasisdurante las últimas décadas, no se han desarrollado recomendacionessobre el mejor tratamiento de la colecistitis aguda litiásica (CA) enPediatría. Caso clínico: Paciente varón de 4 años y 20 kg de peso sin antecedentes de interés, que acude derivado por sepsis de origen abdominal. Analíticamente destaca leucocitosis con hemoglobina, función hepáticay bilirrubina normales. La ecografía abdominal muestra colelitiasis, hidrops vesicular y proceso inflamatorio compatible con plastrón apendicular. En laparoscopia diagnóstica se observa apéndice macroscópicamentenormal y colecistitis aguda. Ante la situación del paciente se realiza,conjuntamente con Cirugía General, colecistectomía laparoscópica. Elpaciente se recupera sin incidencias tras 5 días de ingreso bajo coberturacon piperacilina-tazobactam. Comentarios: No existen recomendaciones sobre el tratamiento dela CA en niños. En los pacientes sépticos, la colaboración entre cirujanospediátricos y cirujanos generales permite contemplar la colecistectomíaurgente como una opción segura.(AU)

Introduction: In spite of the increase in the prevalence of cholelithiasis in the last decades, no recommendations regarding the best treatmentof acute calculous cholecystitis (AC) in pediatrics have been developed. Clinical case: 4-year-old, 20kg male patient with no significanthistory referred to our institution as a result of abdominal sepsis. Theblood count showed leukocytosis, with normal hemoglobin and bilirubinlevels, and a normal liver function. The abdominal ultrasonography revealed cholelithiasis, gallbladder hydrops, and an inflammatory processcompatible with appendicular plastron. In the diagnostic laparoscopy,the appendix was macroscopically normal, and acute cholecystitis wasobserved. Given the patient’s situation, and in cooperation with theGeneral Surgery Department, laparoscopic cholecystectomy was carriedout. The patient recovered uneventfully on hospitalization day 5 underpiperacillin-tazobactam treatment. Discussion: There are no recommendations regarding AC treatmentin children. In septic patients, cooperation between general and pediatricsurgeons allows urgent cholecystectomy to be considered as a safe option.(AU)

Colecistectomía con exploración de vías biliares laparoscópica en paciente con situs inversus totalis

Se presenta el caso de un paciente varón de 77 años con diagnóstico de colecistitis crónica calculosa y coledocolitiasis, con antecedente de situs inversus totalis. Se le realizó una colecistectomía con exploración de vías biliares laparoscópica, utilizando la "técnica francesa en espejo", con extracción de los cálculos. El paciente evolucionó favorablemente. El objetivo del presente trabajo es dar a conocer el caso clínico que es poco frecuente su reporte en la literatura mundial (solo 9 casos). Su importancia radica en que sería el primer reporte de caso clínico publicado de una colecistectomía y exploración de vías biliares laparoscópica con retiro del cálculo en colédoco en un paciente con situs inversus totalis, realizado en el Perú.

We present the case of a 77-year-old male patient with a diagnosis of chronic calculous cholecystitis and choledocholithiasis, with a history of situs inversus totalis. Therefore, a laparoscopic cholecystectomy with common bile duct exploration were performed, using the "french mirror technique", with stone extraction. Patient evolved favorably. The aim of this study is to present this clinical case that is rarely reported in the world literature (only 9 cases). Its importance lies in the fact that it would be the first published clinical case report of a laparoscopic cholecystectomy and bile duct exploration with removal of the common bile duct stones in a patient with situs inversus totalis, performed in Peru.
