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

Íleo biliar: descripción de dos casos / Gallstone ileus: Description of two cases

Introducción. El íleo biliar es una complicación rara de la colelitiasis y su incidencia varía del 1 al 4 %. Consiste en la migración de un cálculo de la vesicular biliar al tracto gastrointestinal, generando obstrucción intestinal. Presenta síntomas inespecíficos dependiendo del nivel de la obstrucción, lo que hace que su diagnóstico no suela ser precoz, repercutiendo en el deterioro clínico del paciente. Es especialmente grave en pacientes de edad avanzada y con comorbilidades. Casos clínicos. Se reportan los casos de dos pacientes con dolor abdominal difuso, en quienes se diagnosticó íleo biliar por tomografía. Se realizó manejo quirúrgico, el primero mediante técnica abierta y estrategia de dos pasos, y el otro mediante técnica laparoscópica. Discusión. El íleo biliar es una etiología rara de obstrucción intestinal. El cálculo migra debido a una fistula colecisto-entérica y el nivel de obstrucción es con mayor frecuencia la válvula ileocecal. Los síntomas son inespecíficos y dependen del nivel de obstrucción: dolor abdominal difuso mal caracterizado, náuseas, vómito, ausencia de flatos. El diagnóstico se hace mediante tomografía abdominal, en la cual se evidencia la tríada de Rigler. El manejo es quirúrgico, con enterotomía para extraer el cálculo y resolver la obstrucción. Conclusión. El íleo biliar es una patología que debe ser considerada en el abordaje de la obstrucción intestinal, aunque sea poco frecuente. El manejo quirúrgico es clave para resolver el cuadro de obstrucción intestinal; aún así genera importante morbimortalidad en especial en pacientes de avanzada edad.

Introduction. Gallstone ileus is a rare complication of cholelithiasis, its incidence varies from 1% to 4%. It consists of the migration of a stone from the gallbladder to the gastrointestinal tract, causing intestinal obstruction. It presents with non-specific symptoms depending on the level of the obstruction, which means that its diagnosis is not usually early, with repercussions on the clinical deterioration of the patient, being serious especially in elderly patients and with comorbidities. Clinical cases. Two patients with diffuse abdominal pain are reported. A tomographic diagnosis was made showing gallstone ileus. Surgeries were performed, in the first case using an open technique and a 2-step strategy, and on the second one using a laparoscopic technique. Discussion. Gallstone ileus is a rare etiology of intestinal obstruction. Symptoms are usually poorly characterized: diffuse abdominal pain, nausea, vomiting, absence of flatus. The diagnosis is made by abdominal tomography in which Rigler's triad is evident. Management is surgical through enterotomy to remove the stone and resolve the obstruction. Conclusion. Gallstone ileus is a rare pathology that should be considered in the approach to intestinal obstruction. Surgical management is key to resolving intestinal obstruction. Even so, it generates significant morbidity and mortality, especially in elderly patients.

Factores asociados con la conversión a técnica abierta en la colecistectomía laparoscópica / Factors associated with conversion to open technique in laparoscopic cholecystectomy

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

Duración de la antibioticoterapia en pacientes con colecistitis aguda manejados con colecistostomía. ¿Afecta los desenlaces clínicos? / Duration of antibiotic therapy in patients with acute cholecystitis managed with cholecystostomy. Does it affect clinical outcomes?

Introducción. En pacientes con diagnóstico de colecistitis aguda tratados con colecistostomía, el tiempo óptimo de duración de la terapia antibiótica es desconocido. El objetivo de este trabajo fue comparar los resultados clínicos en pacientes con diagnóstico de colecistitis aguda manejados inicialmente con colecistostomía y que recibieron cursos cortos de antibióticos (7 días o menos) versus cursos largos (más de 7 días). Métodos. Se llevó a cabo un estudio de cohorte observacional, retrospectivo, que incluyó pacientes con diagnóstico de colecistitis aguda manejados con colecistostomía, que recibieron tratamiento antibiótico. Se hizo un análisis univariado y de regresión logística para evaluar la asociación de variables clínicas con la duración del tratamiento antibiótico. El desenlace primario por evaluar fue la mortalidad a 30 días. Resultados. Se incluyeron 72 pacientes. El 25 % (n=18) recibieron terapia antibiótica por 7 días o menos y el 75 % (n=54) recibieron más de 7 días. No hubo diferencias significativas en la mortalidad a 30 días entre los dos grupos ni en las demás variables estudiadas. La duración de la antibioticoterapia no influyó en la mortalidad a 30 días (OR 0,956; IC95% 0,797 - 1,146). Conclusión. No hay diferencias significativas en los desenlaces clínicos de los pacientes con colecistitis aguda que son sometidos a colecistostomía y que reciben cursos cortos de antibióticos en comparación con cursos largos

Introduction.In patients with acute cholecystitis who receive treatment with cholecystostomy, the optimal duration of antibiotic therapy is unknown. The objective of this study is to compare short courses of antibiotics (7 days or less) with long courses (more than 7 days) in this population. Methods. We performed a retrospective observational cohort study which included patients diagnosed with acute cholecystitis, who received antibiotic therapy and were taken to cholecystostomy. Univariate analysis and logistic regression were performed to evaluate the association between clinical variables and the duration. The main outcome evaluated was 30-day mortality. Results. Seventy-two patients were included, 25% (n=18) were given 7 or fewer days of antibiotics while 75% (n=54) were given them for more than 7 days. Demographic data between both groups were similar (age, severity of cholecystitis, comorbidities). There were no significant differences in 30-day mortality between both groups. Antibiotic duration did not influence mortality at 30 days (OR 0.956, 95% CI 0.797 - 1.146). Conclusion. There are no significant differences in the clinical outcomes of patients with acute cholecystitis who undergo cholecystostomy and receive short courses of antibiotics compared to long courses

Associations of cholecystectomy with the risk of colorectal cancer: a Mendelian randomization study / 中华医学杂志(英文版)

BACKGROUND@#Cholecystectomy is a standard surgery for patients suffering from gallbladder diseases, while the causal effects of cholecystectomy on colorectal cancer (CRC) and other complications are still unknown.@*METHODS@#We obtained genetic variants associated with cholecystectomy at a genome-wide significant level ( P value <5 × 10 -8 ) as instrumental variables (IVs) and performed Mendelian randomization (MR) to identify the complications of cholecystectomy. Furthermore, the cholelithiasis was also treated as the exposure to compare its causal effects to those of cholecystectomy, and multivariable MR analysis was carried out to judge whether the effect of cholecystectomy was independent of cholelithiasis. The study was reported based on Strengthening the Reporting of Observational Studies in Epidemiology Using Mendelian Randomization guidelines.@*RESULTS@#The selected IVs explained 1.76% variance of cholecystectomy. Our MR analysis suggested that cholecystectomy cannot elevate the risk of CRC (odds ratio [OR] =1.543, 95% confidence interval [CI]: 0.607-3.924). Also, it was not significant in either colon or rectum cancer. Intriguingly, cholecystectomy might decrease the risk of Crohn's disease (OR = 0.078, 95% CI: 0.016-0.368) and coronary heart disease (OR = 0.352, 95% CI: 0.164-0.756). However, it might increase the risk of irritable bowel syndrome (IBS) (OR = 7.573, 95% CI: 1.096-52.318). Cholelithiasis could increase the risk of CRC in the largest population (OR = 1.041, 95% CI: 1.010-1.073). The multivariable MR analysis suggested that genetic liability to cholelithiasis could increase the risk of CRC in the largest population (OR = 1.061, 95% CI: 1.002-1.125) after adjustment of cholecystectomy.@*CONCLUSIONS@#The study indicated that cholecystectomy might not increase the risk of CRC, but such a conclusion needs further proving by clinical equivalence. Additionally, it might increase the risk of IBS, which should be paid attention to in clinical practice.

Risco pré-operatório de coledocolitíase em colecistectomiasem um hospital terciário de João Pessoa-PB / Preoperative risk of common bile duct stones in cholecystectomies at a tertiary hospital in João Pessoa-PB

Introdução: a colelitíase é uma das doenças mais comuns do trato digestivo, acometendo 6-10% da população adulta. Destes, aproximadamente 8- 20% apresentam coledocolitíase associada. A estratificação de risco de coledocolitíase pré-operatória nos portadores de colelitíase busca subsidiar a definição de uma terapêutica mais adequada, em tempo hábil, para cada caso. Objetivo:estratificar o risco pré-operatório de coledocolitíase em pacientes submetidos a colecistectomia em um hospital terciário. Metodologia:estudo observacional descritivo, retrospectivo, a partir da análise de prontuários de pacientes submetidos a colecistectomia por cálculos biliares em um hospital público em João Pessoa, Paraíba, entre agosto de 2021 e janeiro de 2022, durante a pandemia de COVID-19. A estratificação de risco foi realizada a partir do estabelecido pela Sociedade Americana de Endoscopia Digestiva (ASGE) em 2010. Resultados: foram selecionados 41 pacientes, a maior parte do sexo feminino, com média de idade de 49,6 anos, em sua maioria submetidos a colecistectomia videolaparoscópica, sem colangiografia intraoperatória. O exame de imagem mais realizado no pré-operatório foi a ultrassonografia de abdome. De acordo com os critérios da ASGE, 18 (43,9%) pacientes foram classificados como baixo risco, 19 (46,4%) foram estratificados no risco intermediário, e 4 foram de alto risco (9,7%). Conclusão: apesar de uma amostra de tamanho limitado, evidencia-se frequência relevante do risco alto ou intermediário de coledocolitíase em portadores de colelitíase. A estratificação de risco para coledocolitíase é uma ferramenta importante a ser utilizada de rotina no pré-operatório da colecistectomia nos pacientes com diagnóstico de colelitíase.

Introduction: gallstones are one of the most common diseases of the digestive tract, affecting 6-10% of the adult population. Of these, approximately 8-20% have associated choledocholithiasis. Preoperative risk stratification of choledocholithiasis in patients with cholelithiasis seeks to allow setting of a proper therapy, in a timely manner, for each case. Objective: stratify preoperative risk of choledocholithiasis in patients undergoing cholecystectomy in a tertiary hospital. Methods: descriptive, retrospective observational study, based on the analysis of medical records of patients undergoing cholecystectomy for gallstones in a public hospital in João Pessoa, Paraíba, between August 2021 and January 2022, during COVID-19 pandemic. Risk stratification was performed based on American Society for Digestive Endoscopy (ASGE) criteria from 2010. Results: 41 patients were evaluated. Most of them were female, with a mean age of 49.6 years, most of whom underwent laparoscopic cholecystectomy without intraoperative cholangiography. The most common imaging performed preoperatively was abdominal ultrasound. According to ASGE criteria, 18 (43.9%) patients were classified as low risk, 19 (46.4%) were stratified into intermediate risk, and 4 scored high risk (9.7%). Conclusion: despite a limited sample size, there is a relevant prevalence of high or intermediate preoperative risk of choledocholithiasis in patients with cholelithiasis. Risk stratification for choledocholithiasis is an important tool to be routinely used in the preoperative period of cholecystectomy in patients with diagnosis of cholelithiasis.

Caracterización de la flora bacteriana en los pacientes con colelitiasis y colecistitis atendidos en un centro hospitalario de alta complejidad / Characterization of the bacterial flora in patients with cholelithiasis and cholecystitis treated in a high complexity hospital

Introducción. Las infecciones del árbol biliar surgen principalmente por estasis asociada a colecistitis aguda, coledocolitiasis y colecistitis alitiásica, siendo pilar del tratamiento un drenaje apropiado y un régimen antibiótico eficaz. El objetivo de esta investigación fue caracterizar la flora bacteriana de los cultivos de bilis. Métodos. Se realizó un estudio observacional, descriptivo, de corte transversal y retrospectivo de pacientes llevados a colecistectomía, colangiopancreatografía retrograda endoscópica y colecistostomía en nuestra institución, a quienes se les tomó cultivo de líquido biliar entre 2017 - 2021. Resultados. Se incluyeron 119 pacientes intervenidos, de los cuales 55,4 % fueron mujeres y el promedio de edad fue de 63,1 (± 16). La clasificación Tokio 2 fue la más frecuente (55,4 %). El germen aislado con mayor frecuencia fue E. coli (51,2 %). El antibiótico más usado fue ampicilina más sulbactam (44,6 %) seguido de piperacilina tazobactam (40,3 %). Conclusión. La Escherichia coli es el germen aislado con mayor frecuencia en infecciones del árbol biliar. No hay claridad con respecto al uso de antimicrobianos de manera profiláctica en esta patología, por esto es conveniente generar protocolos para la toma de muestras y cultivos de bilis en esta población, con el fin de establecer la necesidad del uso de antibióticos y conocer los perfiles de resistencia bacteriana.

Introduction. Infections of the biliary tree arise mainly from stasis associated with acute cholecystitis, choledocholithiasis, and acalculous cholecystitis, with appropriate drainage and an effective antibiotic regimen being the mainstay of treatment. This research is proposed with the aim aim to characterize the bacterial flora of bile cultures.Methods. An observational, descriptive, cross-sectional and retrospective study of patients who underwent cholecystectomy, endoscopic retrograde cholangiopancreatography and cholecystostomy in our institution, whom bile fluid culture was taken between 2017 and 2021, was performed. Results. 119 operated patients were included, of which 55.4% were women, the average age was 63.1 (± 16). The TOKIO 2 classification was the most frequent with 55.4% of the patients. The most frequently isolated germ was E. coli with 51.2%. The most used antibiotic was ampicillin plus sulbactam with 44.6% prescription followed by piperacillin tazobactam with a prescription frequency of 40.3%.Conclusion. Escherichia coli is the most frequently isolated germ in infections of the biliary tree. There is no clarity regarding the use of antimicrobials prophylactically in this pathology. For this reason it is convenient to generate protocols for taking samples and bile cultures in this population, in order to establish the need for the use of antibiotics and to know the profiles of bacterial resistance.

Controversias en cirugía: colelitiasis y coledocolitiasis ¿Exploración de vías biliares laparoscópica más colecistectomía laparoscópica (cirugía en un paso) o CPRE y colecistectomía laparoscópica (cirugía en dos pasos)? / Controversies in surgery: Cholelithiasis and choledocholithiasis - Laparoscopic bile duct exploration plus laparoscopic cholecystectomy (one-step surgery) or ERCP and laparoscopic cholecystectomy(two-step surgery)?

Introducción. La colelitiasis tiene una prevalencia del 15 % y el 21 % tendrá coledocolitiasis al momento de la colecistectomía, con 50 % de probabilidad de presentar complicaciones asociadas. Desde el advenimiento de la colecistectomía laparoscópica, el abordaje de la coledocolitiasis ha sido endoscópico, usualmente en un tiempo diferente al vesicular, sin embargo, los avances en laparoscopia han permitido explorar la vía biliar común por la misma vía, pudiendo realizar ambos procedimientos en el mismo tiempo de forma segura. Métodos. Se realizó una búsqueda de la literatura existente con relación al enfoque para el manejo de la colecisto-coledocolitasis en un paso comparado con dos pasos. Resultados. Existe evidencia que demuestra mayor efectividad del abordaje en dos pasos, con CPRE y posterior colecistectomía laparoscópica, sobre el abordaje en un paso, especialmente en la tasa de fuga biliar y de cálculos retenidos. El enfoque en un paso con exploración de vías biliares y colecistectomía laparoscópica en el mismo tiempo es seguro, con alta tasa de éxito, baja incidencia de complicaciones, menor estancia hospitalaria y costos. Conclusión. El abordaje laparoscópico en un solo paso es un procedimiento seguro y eficaz para el manejo de la colecisto-coledocolitiasis, con el beneficio de estancia hospitalaria menor, sin embargo, se requieren habilidades técnicas avanzadas en cirugía laparoscópica. En nuestro medio ya existe una infraestructura para el manejo híbrido con CPRE y colecistectomía laparoscópica, pudiéndose realizar ambos en el mismo tiempo, para reducir estancia y costos.

Introduction. Cholelithiasis has a prevalence of 15%, and 21% will have choledocholithiasis at the time of cholecystectomy, with a 50% probability of presenting associated complications. Since the advent of laparoscopic cholecystectomy, the approach to choledocholithiasis has been endoscopic, normative at a different time than the gallbladder; however, advances in laparoscopy have made it possible to explore the common bile duct by the same route, being able to perform both procedures in a single time safely. Methods. A search of the existing literature was performed regarding the one-step approach compared to the two-step approach for the management of cholelithiasis and choledocholithiasis. Results. There is evidence that demonstrates greater effectiveness of the two-step approach with ERCP and subsequent laparoscopic cholecystectomy over the one-step approach, especially in the rate of bile leak and the incidence of retained stones. The one-step approach with bile duct exploration and laparoscopic cholecystectomy at the same time is safe, with a high success rate, low incidence of complications, shorter hospital stay, and lower costs. Conclusion. The one-step laparoscopic approach is a safe and effective procedure for the management cholelithiasis and concomitant choledocholithiasis, with the benefit of a shorter hospital stay; however, advanced technical skills in laparoscopic surgery are required. In our environment there is already an infrastructure for hybrid management with ERCP and laparoscopic cholecystectomy, both of which can be performed at the same time to reduce hospital stay and costs.

Íleo biliar: reporte de casos / GALLSTONE ILEUS: CASES REPORT

El íleo biliar se define como una obstrucción intestinal mecánica secundaria a la presencia de un cálculo biliar. Menos del 1% de los casos de obstrucción intestinal se derivan de esta etiología. La causa más frecuente es la impactación del cálculo en el íleon, tras su paso por una fístula bilioentérica. Es una complicación rara y potencialmente grave de la colelitiasis. Esta patología se presenta más en adultos mayores, la edad promedio en la que se presenta es entre los 60 y 84 años, afectando principalmente al sexo femenino, atribuido a la mayor frecuencia de patología biliar en dicho sexo. Presenta una alta morbimortalidad, principalmente por la dificultad y la demora diagnóstica.

Gallstone ileus is defined as a mechanical intestinal obstruction secondary to the presence of a gallstone. Less than 1% of cases of intestinal obstruction are derived from this etiology. Te most frequent cause is the impaction of the stone in the ileum, after passing through a bilioenteric fistula. It is a rare and potentially serious complication of cholelithiasis. Tis pathology occurs more in the elderly, the average age at which it occurs is between 60 and 84 years, mainly affecting the female sex, attributed to the higher frequency of biliary pathology in said sex. It presents a high morbidity and mortality, mainly due to the difficulty and the diagnostic delay

Factores de riesgo prequirúrgicos para una colecistectomía laparoscópica difícil / Preoperative risk factors for difficult laparoscopic cholecystectomy

RESUMEN Antecedentes: varios estudios observacionales han identificado factores de riesgo (FR) para una colecistectomía laparoscópica difícil (CLD). Objetivo: identificar los FR preoperatorios para CLD en un hospital público de mediana complejidad. Material y métodos: estudio prospectivo de cohorte transversal. Se analizaron 80 pacientes mayores de 18 años sometidos a colecistectomía laparoscópica, entre enero y diciembre de 2019. Se analizaron las variables: edad, sexo, IMC (índice de masa corporal), litiasis vesicular, pancreatitis aguda, colecistitis aguda o crónica, síndrome de Mirizzi, CPRE dentro del mes, numero de cólicos en el último mes, si presentó al menos un cólico en la última semana, leucocitos, enzimas hepáticas mayores, bilirrubina total, hallazgos de ecografía prequirúrgicos, antecedentes de cirugías abdominales previas. Resultados: la incidencia de CLD fue de 47,5%. La tasa de conversión a cirugía convencional fue del 11,25%, el 100% fueron CLD. Los FR para CLD incluyeron sexo masculino (OR: 4,50, IC 95%:1,60-12,62, p: 0,004), cólico en la semana previa a la cirugía (OR:7,17, IC 95%:1,89-27,23, p: 0,004), paredes engrosadas de la vesícula (OR: 4.90, IC 95%:1,90-12,70, p: 0,001), edema perivesicular (OR: 7,14 IC 95%:1,45-35,13 p: 0,016), la vesícula hidrópica (OR: 4,94, IC 95%:1,44-16,88, p: 0,011) y las cirugías previas (OR: 4.38 IC 95%:1,27-15,10 p: 0,001). En el análisis multivariado vemos que los pacientes de sexo masculino y pacientes con cirugías previas presentaban un riesgo elevado para CLD (OR: 6,63 IC 95%:1,75-25,08 p: 0.005; OR: 11.70 IC 95%:1,48-92,37 p: 0,020). Conclusión: se deben centrar los esfuerzos en identificar los pacientes con sospecha de CLD, pudiendo planificar la cirugía y un equipo quirúrgico experimentado.

ABSTRACT Background: The risk factors (RF) for difficult laparoscopic cholecystectomy (DLC) have been identified in many observational studies. Objective: The aim of this study is to identify the preoperative RF for DLC in a secondary care public hospital. Material and methods: We conducted a prospective cross-sectional cohort study of patients > 18 years undergoing laparoscopic cholecystectomy between January and December 2019. The following variables were analyzed: age, sex, body mass index (BMI), cholelithiasis, acute pancreatitis, acute or chronic cholecystitis, Mirizzi syndrome, ERCP within the previous month, episodes of biliary colic in the last month, presence of at least one colic within one week before surgery, white blood cell count, liver enzymes, total bilirubin, preoperative ultrasound and history of upper abdomen surgery. Results: The rate of DLC was 47.5%. Conversion rate to conventional surgery was 11.25% and 100% were categorized as DLC. The RF for DLC included male sex (OR, 4.50; 95% CI,1.60-12.62; p = 0.004), colic within 1 week before surgery (OR, 7.17; 95% CI,1.89-27.23; p = 0.004), gallbladder wall thickening (OR, 4.90; 95% CI,1.90-12.70; p = 0.001), edema around the gallbladder (OR, 7.14; 95% CI, 1.45-35.13; p = 0.016), hidrops gallbladder (OR, 4.94; 95% CI,1.44-16.88; p = 0.011) and previous surgeries (OR, 4.38; 95% CI, 1.27-15.10; p = 0.001). On multivariate analysis, male sex and previous surgery were associated with higher risk of DLC (OR, 6.63; 95% CI,1.75-25.08; p = 0.005; and OR, 11.70, 95% CI,1.48-92.37; p = 0.020, respectively). Conclusion: Efforts should focus on identifying patients with suspicion of DLC to plan surgery with an experienced surgical team.

Severidad de la colecistitis aguda en tiempos de COVID-19: ¿mito o realidad? / Severity of acute cholecystitis in times of COVID-19: myth or reality?

Introducción. La colecistitis aguda es una de las causas más frecuentes de ingresos hospitalarios y la colecistectomía laparoscópica es el estándar de oro para su manejo. Dentro de los efectos de la pandemia por COVID-19 se ha percibido un aumento en la severidad de presentación en estos pacientes. Este estudio tuvo como objetivo comparar la presentación clínica y quirúrgica de la colecistitis aguda antes y durante la pandemia por COVID-19. Métodos. Estudio retrospectivo de una cohorte con pacientes llevados a colecistectomía laparoscópica por colecistitis aguda entre 2019 y 2020. Se realizó un análisis bivariado y de Kaplan Meier con el tiempo transcurrido entre inicio de síntomas y el ingreso al hospital, y entre el ingreso del hospital y la realización de la cirugía. Resultados. Fueron llevados a colecistectomía laparoscópica por colecistitis aguda un total de 302 pacientes. El tiempo de evolución de los síntomas hasta el ingreso fue de 83,3 horas (IC95%: 70,95 ­ 96,70) antes de la pandemia y 104,75 horas (IC95%: 87,26 ­ 122,24) durante la pandemia. El tiempo entre el ingreso al hospital y el procedimiento quirúrgico fue significativamente menor en el período de pandemia (70,93 vs. 42,29; p<0,001). El porcentaje con mayor severidad (Parkland 5) fue igual antes y durante la pandemia (29 %). Conclusión. Se reporta una severidad clínica y quirúrgica similar antes y durante la pandemia por COVID-19, probablemente secundario a los resultados de un tiempo de entrada al quirófano significativamente menor durante la pandemia, debido a una mayor disponibilidad de quirófanos para las patologías quirúrgicas urgentes.

Introduction. Acute cholecystitis is one of the most frequent causes of hospital admissions in the adult population and laparoscopic cholecystectomy is considered the gold standard for its management. Within the effects of the COVID-19 pandemic, an increase in the severity of presentation has been perceived in these patients. This study aims to compare the clinical and surgical presentation based on the different severity scales of acute cholecystitis before and during the COVID-19 pandemic. Methods. A retrospective cohort study was performed with patients undergoing laparoscopic cholecystectomy for acute cholecystitis between 2019 and 2020. A bivariate and Kaplan Meier analysis was performed with the time elapsed between onset of symptoms and admission to hospital, and between admission to hospital and performance of surgery. Results. A total of 302 patients underwent laparoscopic cholecystectomy for acute cholecystitis. The time of evolution of symptoms until admission was 83.3 hours (95% CI: 70.95 - 96.70) vs. of 104.75 hours (95% CI: 87.26 - 122.24) before and during the pandemic, respectively. The time between admission to the hospital and the surgical procedure was significantly shorter in the current pandemic period (70.93 vs. 42.29; p<0.001). The patients with greater severity (Parkland 5) was the same before and during pandemic (29%). Conclusion. Similar clinical and surgical severity is reported before and during the COVID 19 pandemic, probably secondary to the results of a significantly shorter entry time to the operating room during the pandemic, due to a greater availability of operating rooms for urgent surgical pathologies.

Estudio complementario de la patología biliar complicada y el manejo de la litiasis coledociana en dos tiempos / Complementary evaluation of complicated gallstone disease and two-stage management of choledochal lithiasis

RESUMEN Antecedentes: la litiasis biliar tiene una prevalencia actual en Occidente del 10-20%. El 7-16% de los pacientes presentan también coledocolitiasis. El diagnóstico preoperatorio de coledocolitiasis es difícil de establecer. Objetivo: establecer nuestra experiencia en el estudio de la patología biliar complicada y el manejo de la coledocolitiasis en dos tiempos, como terapéutica de elección. Material y métodos: estudio prospectivo, observacional. Pacientes con patología biliar sometidos a procedimientos en el Servicio de Cirugía General del Hospital Vidal, desde el 30/06/2019 al 30/12/2019. Resultados: la ecografía hepato-bilio-pancreática (HPB) es específica, con exactitud del 80,9% y sensibilidad del 50%. La colangio resonancia magnética (CRNM) es 100% específica, tiene exactitud del 84,6% y sensibilidad de 67%. La colangio pancreatografía retrógrada endoscópica (ERCP -por sus siglas en inglés-), durante la primera colangiografía mostró en el 100% litiasis coledociana, pero, luego del tratamiento, la colangiografía de "control" muestra 0% de sensibilidad, 100% especificidad, con exactitud del 15,4%. En los hallazgos intraoperatorios, el cístico dilatado en asociación con alteraciones humorales ha demostrado una sensibilidad del 100%, especificidad del 90% y tasa de exactitud de 93,6%. Conclusión: la colangiografía intraoperatoria (CIO) es el procedimiento de referencia ("gold standard") en el abordaje de la patología biliar complicada, siendo su uso sistemático. La asociación entre alteraciones de parámetros humorales y el cístico dilatado resulta un parámetro con alto valor predictivo para la presencia de litiasis coledociana.

ABSTRACT Background: Nowadays, the prevalence of gallstones ranges between 10 and 20% in Western world, and 7-16% of the patients also present choledocholithiasis. The preoperative diagnosis of choledocholithiasis is difficult. Objective: To establish our experience in the evaluation of complicated gallstone disease and two-stage management of choledochal lithiasis as standard or care. Material and methods: This prospective and observational study included patients hospitalized with gallstone disease undergoing procedures in the Department of General Surgery of Hospital Vidal from June 30, 2019, to December 30, 2019. Results: Ultrasound of the liver, biliary tract and pancreas was specific, with accuracy of 80.9% and sensitivity of 50%. Magnetic resonance cholangiopancreatography (MRCP) had a sensitivity of 100%, accuracy of 84.6% and sensitivity of 67%. As for endoscopic retrograde cholangiopancreatography (ERCP), the diagnosis of choledocholithiasis was made in 100% of the cases during the first cholangiography while "control" cholangiography had a sensitivity of 0%, specificity of 100% and accuracy of 15.4%. The presence of a dilated cystic duct intraoperatively in association with abnormal biochemical parameters had a sensitivity of 100%, specificity of 90%, and accuracy of 93.6%. Conclusion: Intraoperative cholangiography (IOC) is the gold standard procedure for the management of complicated gallstone disease. The association of biochemical parameters and a dilated cystic duct has high predictive value for choledochal lithiasis.

Dilataciones quísticas congénitas de las vías biliares (primera parte). Vías biliares intrahepáticas / Congenital bile duct cystic dilatation (part 1). Intrahepatic bile ducts

RESUMEN La enfermedad de Caroli es una enfermedad infrecuente que requiere un alto índice de sospecha para su diagnóstico. Puede afectar un segmento hepático, un lóbulo o todo el hígado; suele generar episodios repetidos de colangitis. Existe una amplia gama de propuestas terapéuticas que oscilan desde el tratamiento médico hasta el trasplante de hígado. En este trabajo presentamos 3 casos, realizamos una revisión de la literatura y proponemos una ampliación de la clasificación de Alonso-Lej modificada por Todani que, a nuestra manera de ver, tiene implicaciones a la hora de seleccionar un tratamiento.

ABSTRACT Caroli's disease is a rare condition, and its diagnosis requires high level of suspicion. The disease may affect one segment, one lobe or the entire liver, and may result in repeated episodes of cholangitis. The disease can be managed using different therapeutic approaches ranging from medical treatment to liver transplantation. In this paper we report 3 cases with review of the literature and propose a modification of the classification by Alonso-Lej modified by Todani which we believe may be useful to guide treatment.

Laparoscopic cholecystectomy by the modified bikini line approach as a simple and safe technique

SUMMARY OBJECTIVE The gold standard technique for laparoscopic cholecystectomy (LC) is using four ports in the upper abdomen. However, this operative approach may not provide aesthetic satisfaction for some patients because of visible incision marks. This study sought to demonstrate that these incision marks can be hidden by safely changing the port locations. METHODS For patients with symptomatic cholelithiasis undergoing LC between March 2019 and March 2020, the modified bikini line approach was used. With the patient in the supine position with open legs, the first trocar (10 mm) was inserted into the abdomen through an 11-mm incision in the umbilicus. The other three trocars were placed in the abdomen at the bikini line with the help of a camera. The standard equipment for LC was then used to perform the surgery. RESULTS The modified bikini line approach to LC was used for 38 patients. Average operative time was 28.65 min, and the average hospital stay was 1.07 days. No perioperative or postoperative complications occurred. Follow-up was at 1 week, 1 month, and 6 months. Cosmetic results were satisfactory for all patients. CONCLUSIONS As an alternative to the standard LC approach, the modified bikini line technique is safe and useful in patients for whom postoperative aesthetic appearance is important. The modified approach is simple to learn and use and is effective to hide the incision marks well.

Síndrome de Mirizzi tipo V: Manejo laparoscópico / Mirizzi syndrome type V: laparoscopic management

Resumen Introducción: El Síndrome de Mirizzi es una complicación infrecuente de la enfermedad litiásica biliar, con una incidencia menor al 1% en países desarrollados, puede desarrollarse en cinco variantes, siendo menos frecuente la variante tipo V. La literatura actual discrepa sobre el manejo de esta condición, afirmando que la cirugía laparoscópica no es segura como procedimiento estándar. Caso Clínico: Se presenta el caso de Síndrome de Mirizzi en un hombre de 80 años, que es remitido al departamento de urgencias por sospecha de sepsis de origen abdominal, con estudio ecográfico de colelitiasis, neumobilia y dilatación de las vías biliares. Se realizó Colangiopancreatografía retrógrada endoscópica con imposibilidad técnica para la movilización y extracción de los cálculos por gran tamaño, recurriéndose a exploración a través de técnica laparoscópica, obteniéndose resultados satisfactorios. Conclusión: Para tratar el Síndrome de Mirizzi, es necesario considerar las características del paciente y la experiencia del cirujano ya que ambos factores influyen directamente en la modalidad del tratamiento, sus complicaciones y tasas de éxito. En el presente caso, la experiencia del autor principal en el manejo de procedimientos mínimamente invasivos y la consideración de reducir el riesgo de complicaciones como infecciones en un paciente frágil, fueron los factores que influyeron para la decisión de intervención laparoscópica.

Abstract Introduction: Mirizzi's syndrome is an infrequent complication of biliary lithiasic disease, with an incidence of less than 1% in developed countries, being even less frequent the type V variant. Current literature disagrees on the management of this condition, stating that laparoscopic surgery is not safe as a standard procedure. Clinical Case: We present the case of Mirizzi's Syndrome in an 80-year-old man, which is referred to the emergency department for suspicion of sepsis of abdominal origin, with ultrasound study of cholelithiasis, pneumoobilia and dilation of the bile ducts. Retrograde endoscopic cholangiopancreatography was performed with technical impossibility for the mobilization and extraction of large-size stones, resorting to exploration through laparoscopic technique, obtaining satisfactory results. Conclusion: It is necessary to emphasize that the type of Mirizzi syndrome, the patient's characteristics and the surgeon's experience directly influence the treatment modality, its complications and/or success rates. In the present case, the experience of the main author in the management of minimally invasive procedures and the consideration of reducing the risk of complications such as infections in a fragile patient, were the factors that influenced the decision for laparoscopic intervention.
