Perforación colónica por endoprótesis biliar impactada / Colonic perforation due to impacted biliary stent

Introducción. La colocación de endoprótesis biliares es cada día más frecuente por ser actualmente una de las mejores opciones para el tratamiento de patologías de la vía biliar. La migración de las endoprótesis es una de las complicaciones que puede ocurrir en hasta un 10,8 % de los pacientes, pero en muy raras ocasiones llegan a causar una perforación intestinal. Caso clínico. Se trata de una paciente de 61 años, a quien cinco años atrás se le realizó una colangiopancreatografía retrógrada endoscópica por coledocolitiasis. Consultó por presentar dolor abdominal, y al examen físico se encontraron abdomen agudo y plastrón en fosa ilíaca izquierda a la palpación. La tomografía computarizada informó un cuerpo extraño a nivel del colon descendente, con perforación del mismo. Se realizó laparotomía exploratoria y colostomía por perforación del colon sigmoides secundaria a prótesis biliar migrada. Resultados. La paciente evolucionó favorablemente y a los seis meses se realizó el cierre de la colostomía, sin complicaciones. Conclusión. Los pacientes a quienes se les colocan prótesis biliares requieren un seguimiento adecuado para evitar complicaciones que, aunque raras, pueden ocurrir, como la migración intestinal con perforación. El tratamiento de dichas complicaciones se hace por vía endoscópica, laparoscópica o laparotomía en caso de complicación severa.

Introduction. Endoscopic placement of biliary stents is becoming more common every day, as it is currently one of the best options for the treatment of bile duct pathologies. One of the complications that can occur is the migration of the endoprostheses in up to 10.8% of patients, which in very rare cases can cause intestinal perforation. Clinical case. This is a 61-year-old female patient, who underwent endoscopic retrograde cholangiopancreatography five years ago for choledocholithiasis. She consulted due to abdominal pain, with a physical examination that upon palpation documented an acute abdomen and a palpable plastron in the left iliac fossa. The computed tomography revealed a foreign body at the level of the descending colon, with perforation. Exploratory laparotomy and colostomy were performed due to perforation of the sigmoid colon secondary to migrated biliary prosthesis. Results. The patient progressed favorably and six months later the colostomy was closed without complications. Conclusions. Patients who receive biliary stents require adequate follow-up to avoid complications that, although rare, may occur, such as intestinal migration with intestinal perforation. The treatment of these complications can be endoscopic, laparoscopic or laparotomy in case of severe complication.

Colangiopancreatografía endoscópica asistida por laparoscopia para el tratamiento de coledocolitiasis en pacientes con Y de Roux / Laparoscopic-assisted endoscopic cholangiopancreatography for the treatment of choledocholithiasis in patients with Roux-en-Y

Introducción. Los pacientes con antecedente de baipás gástrico que presentan coledocolitiasis no pueden ser tratados con la técnica convencional de colangiopancreatografía retrógrada endoscópica. En estos casos, la vía transgástrica abierta o asistida por laparoscopia, se convierte en una excelente alternativa a la exploración abierta de la vía biliar. Métodos. Estudio retrospectivo que incluyó pacientes adultos con coledocolitiasis y antecedente de gastrectomía subtotal o baipás gástrico con Y de Roux, llevados a colangiopancreatografía endoscópica transgástrica laparo-asistida, entre enero de 2019 y diciembre de 2021, en la Clínica CES de Medellín, Colombia. Resultados. Se encontraron siete pacientes, todos con antecedente de baipás gástrico para el manejo de la obesidad. La tasa de identificación y canulación de la vía biliar y extracción de cálculos fue del 100 % mediante el abordaje transgástrico laparo-asistido. Conclusión. De acuerdo con varias revisiones sistemáticas, esta técnica es relativamente fácil de implementar y segura, presentando una tasa de complicaciones inferior a 5 %. Se propone una variante de esta técnica

Introduction. Patients with a history of gastric bypass who present with choledocholithiasis cannot be treated with the conventional technique of endoscopic retrograde cholangiopancreatography. In these cases, the open or laparoscopic-assisted transgastric approach becomes an excellent alternative to open bile duct gastric exploration. Methods. A retrospective review of patients with choledocholithiasis and a history of subtotal gastrectomy or gastric bypass with Roux-en-Y, who underwent laparo-assisted transgastric endoscopic cholangiopancreatography, was conducted between January 2019 and December 2021 at Clínica CES de Medellín, Colombia. Results. Seven patients were found, all with a history of gastric bypass secondary to obesity. The rate of bile duct identification and cannulation, and stone removal was 100% using the laparo-assisted transgastric approach. Conclusion. According to several systematic reviews, this technique is relatively easy to implement and safe, presenting a rate of complications less than 5%. A variant to this technique is proposed

Colangiografía videolaparoscópica intraoperatoria y colangiopancreatografía retrógrada endoscópica en pacientes con sospecha de colédocolitiasis / Intraoperative Videolaparoscopic Cholangiography and Endoscopic Retrograde Cholangiopancreatography in Patients with Suspected Choledocholithiasis

Introducción: La coledocolitiasis se ha convertido en un problema de salud para el cual existen disímiles opciones de tratamiento. Objetivo: Exponer los resultados obtenidos con la colangiografía videolaparoscópica intraoperatoria y la colangiopancreatografía retrógrada endoscópica en pacientes con sospecha de coledocolitiasis. Métodos: Se realizó un estudio descriptivo retrospectivo en pacientes con sospecha de coledocolitiasis sometidos a colangiografía videolaparoscópica y la colangiopancreatografía endoscópica en el Hospital Militar Clínico Quirúrgico Docente de Camagüey Dr. Octavio de la Concepción y de la Pedraja durante el período de enero de 2015 a diciembre de 2019. El universo lo conformaron los 117 pacientes sometidos a ambos procederes. Se controlaron las variables de sospecha de coledocolitiasis, grupos de edades, sexo, hallazgos imagenológicos, complicaciones e índice de sospecha de coledocolitiasis. Resultados: En la colangiografía videolaparoscópica intraoperatoria fue mayor la posibilidad diagnóstica y menor las complicaciones. El diagnóstico de coledocolitiasis fue mayor en los pacientes sometidos a colangiopancreatografía retrógrada endoscópica, aunque esta no permitió evaluar a pacientes con bajo riesgo. Los pacientes del sexo femenino fueron más frecuentes en ambos grupos y la sospecha de coledocolitiasis se observó en grupo de edades entre 31 y 45 años. Sin embargo, fue normal el hallazgo de las vías biliares en ambos procederes. Conclusiones: Ambos métodos son seguros y útiles en el estudio en pacientes con sospecha de coledocolitiasis, con mayor eficacia diagnóstica para la técnica videolaparoscópica y menos complicaciones. El hallazgo normal de la vía biliar fue el resultado que prevaleció en ambos procederes(AU)

Introduction: Choledocholithiasis has become a health problem for which there are dissimilar treatment options. Objective: To present the results obtained with intraoperative videolaparoscopic cholangiography and endoscopic retrograde cholangiopancreatography in patients with suspected choledocholithiasis. Methods: A retrospective and descriptive study was conducted in patients with suspected choledocholithiasis and submitted to videolaparoscopic cholangiography and endoscopic cholangiopancreatography at Hospital Militar Clínico Quirúrgico Docente Dr. Octavio de la Concepción y de la Pedraja, of Camagüey, during the period from January 2015 to December 2019. The study universe consisted of 117 patients submitted to both procedures. The variables of suspected choledocholithiasis, age groups, sex, imaging findings, complications and index of suspected choledocholithiasis were controlled. Results: Intraoperative videolaparoscopic cholangiography had a higher diagnostic possibility and lower complications. The diagnosis of choledocholithiasis was higher in patients submitted to endoscopic retrograde cholangiopancreatography, although this did not allow the assessment of low-risk patients. Female patients were more frequent in both groups, while suspected choledocholithiasis was observed in patients between 31 and 45 years of age. However, the finding of a normal biliary tract was common to both procedures. Conclusions: Both methods are safe and useful in the study in patients with suspected choledocholithiasis, with greater diagnostic efficacy, as well as fewer complications, for the videolaparoscopic technique. The finding of a normal biliary tract was the prevailing result in both procedures(AU)

Clinical profile and treatment outcomes of acute cholangitis in children in a Tertiary Government Hospital in the Philippines: A five-year retrospective study

Background@#Acute cholangitis (AC) in children is a rare but life-threatening infection. Symptoms vary from mild to severe disease. There are no local published data on pediatric AC.@*Objective@#To determine the clinical, biochemical, ultrasonographic, microbiologic features, and treatment outcome of pediatric patients with definite AC.@*Methodology@#Cross-sectional study using medical records of pediatric patients diagnosed with definite AC based on the Modified Tokyo Guidelines of 2018 admitted from January 2016 to June 2021.@*Results@#Twenty-seven patients aged 0 to 18 years old (10.06 + 7.34), predominantly male (51.85%) were included. Choledocholithiasis (22%) and post-Kasai biliary atresia (22%) were the common underlying biliary conditions. Fever (88.89%) was the most frequent presenting symptom. Majority were classified as moderate AC (40.74%). Leukocytosis (mean 16×109/L), elevated inflammatory markers (93.33% with CRP >12mg/L and 100% with serum procalcitonin >0.25ng/mL), hyperbilirubinemia (total bilirubin 192.54±126.87umol/L) and elevated alanine transferases (mean 59 IU/L) were noted. Twenty-one out of 27 cases (87%) had a negative blood culture. Only 4 patients underwent bile culture, of which two (50%) grew Klebsiella pneumoniae resistant to empiric antibiotics. Dilated biliary ducts were observed on abdominal ultrasound in 92.59% of patients. Ampicillin-sulbactam (29.63%) was the most commonly utilized antibiotic. Discharge rate was high (88.89%).@*Conclusions@#AC affects all pediatric age groups but clinical presentations vary. Drug resistant organisms are a significant concern but despite this, favorable outcomes have been documented.

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.

Innovación en técnica quirúrgica: Dos técnicas no convencionales para el tratamiento de la coledocolitiasis / Innovative surgical techniques. Two non-conventional techniques for the treatment of choledocholithiasis

RESUMEN La litiasis vesicular asociada a coledocolitiasis puede tener distintos tratamientos, endoscópicos o quirúrgicos, dependiendo del paciente, el entrenamiento del personal médico y de la disponibilidad de instrumental. Ninguno ha demostrado estar exento de complicaciones. Presentamos dos técnicas tendientes a mejorar los resultados del tratamiento quirúrgico de la coledocolitiasis. Una es la extracción transcística de coledocolitiasis y stent, en pacientes que fueron tratados endoscópicamente por colangitis, tendiente a resolver el problema (la litiasis vesicular, la coledocolitiasis y el stent) en un solo tiempo por cirugía laparoscópica. La segunda es una nueva indicación de una técnica ya descripta, la dilatación papilar anterógrada con balón, utilizada en este caso para disminuir las fugas biliares tras un cierre primario de colédoco.

ABSTRACT Cholelithiasis associated with choledocholithiasis may have different treatments, either by endoscopy or surgery, depending on the patient, level of training of the medical staff and availability of instruments. None of them is free of complications. We report two non-conventional techniques aimed at improving the results of the management of choledocholithiasis. Transcystic removal of common bile duct stones and stent in patients who underwent endoscopic treatment for cholangitis is one of these new techniques to manage cholelithiasis, choledocholithiasis and stent removal in a single procedure through laparoscopy. The second technique is a new indication of a previously described procedure, antegrade balloon papillary dilation to reduce biliary leaks after primary closure of the common bile duct.

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.

Hipertransaminasemia en coledocolitiasis / Hypertransaminasemia in choledocholithiasis

Introducción. La coledocolitiasis aguda se presenta cuando un cálculo se impacta en el conducto biliar distal. Usualmente se manifiesta con un patrón colestásico, con aumento de la AST y ALT leve o moderado. Sin embargo, se han reportado series de casos de coledocolitiasis con AST y ALT con valores >400 UI/L, lo que puede llevar al médico a considerar una hepatitis como diagnóstico presuntivo, en vez de una coledocolitiasis. Con esta revisión exploratoria se pretende explicar esta forma de presentación, y sugerir los pasos que debe dar el clínico para identificar estos casos y brindar un diagnóstico oportuno y certero. Metodología. Se realizó una revisión exploratoria utilizando los buscadores PubMed, BIREME (BVS), LILACS y Google Académico, con las palabras MeSH "choledocholithiasis", "transaminases" y el conector "and", así como los términos DeCS "coledocolitiasis", "transaminasas" y el conector "y". Resultados. Se incluyeron en el análisis un total de 20 estudios relacionados con el tema coledocolitiasis y elevación de AST o ALT >400 UI/L. Se encontró que el aumento de AST o ALT entre 400 UI/L y 500 UI/L se presentó en el 5,76% de los casos, valores entre 500 UI/L y 800 UI/L en el 36,8%, entre 800 UI/L y 1.000 UI/L en el 9%, y valores >1.000 UI/L en el 6,43% de los casos. Conclusión. La coledocolitiasis con elevación de transaminasas AST o ALT >400 UI/L es una situación que debe tenerse presente, en particular en personas jóvenes, y en aquellos sin historia de problemas hepáticos previos. Es necesario que el médico tenga el diagnóstico presuntivo de coledocolitiasis, aun con niveles de transaminasas que puedan sugerir una hepatitis, y analizar las diferentes variables que son indispensables para lograr un diagnóstico preciso.

Introduction. Acute choledocholithiasis occurs when a stone impacts the distal bile duct. It usually manifests with a cholestatic pattern, with a mild or moderate increase in ASL and ALT. However, series of cases of choledocholithiasis have been reported with AST and ALT values >400 IU/L, which may lead the physician to consider hepatitis as a presumptive diagnosis, instead of choledocholithiasis. This scoping review is intended to explain this form of presentation, and to suggestthe steps that the clinician should take to identify these cases and provide a timely and accurate diagnosis. Methodology. A scoping review was carried out using PubMed, BIREME (BVS), LILACS and Google Scholar search engines, with the MeSH words "choledocholithiasis", "transaminases" and the "and" connector, as well as the DeCS terms "coledocolitiasis", "transaminasas" and the "y" connector. Results. A total of 20 studies related to the topic of choledocholithiasis and elevation of AST or ALT >400 IU/L were included in the analysis. It was found that the increase in AST or ALT between 400 IU/L and 500 IU/L occurred in 5.76% of the cases, values between 500 IU/L and 800 IU/L in 36.8%, between 800 IU/L and 1,000 IU/L in 9%, and values >1,000 IU/L in 6.43% of the cases. Conclusion. Choledocholithiasis with elevated AST or ALT transaminases >400 IU/L is an occurrence that should be taken into account, particularly in young people, and in those without a history of previous liver problems. It is necessary for the specialist to have a presumptive diagnosis of choledocholithiasis, even with transaminase levels that may suggest hepatitis, and to analyze the different variables that are essential to achieve an accurate diagnosis.

Laparoscopic Common Bile Duct Exploration for Treatment of Common Bile Duct Stones:Clinical Analysis of 158 Cases / 中国医学科学院学报

Objective To evaluate the safety and effectiveness of laparoscopic common bile duct exploration in the treatment of common bile duct stones. Methods A retrospective analysis was conducted for 158 patients with cholecystolithiasis and choledocholithiasis admitted to the Number One Hospital of Zhangjiakou from January 2015 to December 2019.The patients were assigned into three groups according to the diameters of cystic duct and common bile duct,degrees of abdominal infection and tissue edema,and operation method.Group A(16 cases):laparoscopic cholecystectomy,transcystic choledochoscopic exploration for stone removal;Group B(94 cases):laparoscopic cholecystectomy,common bile duct incision exploration combined with choledochoscopy for stone removal,T tube drainage;Group C(48 cases):laparoscopic cholecystectomy,common bile duct incision exploration combined with choledochoscopy for stone removal,primary closure of the common bile duct.The operation time,residual rate of stones,and complication(bleeding,bile leakage,and wound infection) rate were compared between groups. Results The operation time of groups A,B,and C was(95.1±14.7),(102.2±18.1),(110.1±16.4) minutes,respectively,which showed no statistical difference between each other(F=0.020,P=0.887).One case in group A had residual stones,while no residual stone appeared in groups B and C.The overall stone clearance rate was 99.4% and the overall complication rate was 1.9%.There was no perioperative death. Conclusion It is generally safe and effective to carry out laparoscopic cholecystectomy and common bile duct exploration for stone removal in suitable populations.

A retrospective comparative study between early (≤ 72 hrs) and late (> 72 hrs) Laparoscopic Cholecystectomy after ERCP in St. Paul’s Hospital Iloilo

Objective@#The study was performed to assess and compare the effect of early (≤ 72 hours) and late (>72 hours) laparoscopic cholecystectomy after Endoscopic retrograde cholangio pancreatography (ERCP) in terms of duration of operation, conversion to open cholecystectomy, intraoperative complicating factors, duration of hospital stay from the date of ERCP, hospital expenses, and presence of postoperative complications.@*Methods@#This is a retrospective study from 2010 up to July 2019. Outcomes (duration of operation, rate of conversion, intraoperative complicating factors, length of hospital stay, hospital expenses and post-operative complications) were compared between patients who had ERCP then cholecystectomy within 72 hours (Early Group) and those who had ERCP then cholecystectomy after more than 72 hours (Late Group). @*Results@#A total of 19 patients were included in this study. There were 10 patients in the Early Group and 9 in the Late Group. Early laparoscopic cholecystectomy after ERCP had a shorter statistically significant duration of hospital. Shorter operative time, fewer intraoperative complicating factors, no conversion to open cholecystectomy, cheaper hospital expenses and no post-operative complications were also noted in the Early Group as compared to the Late Group.@*Conclusion@#Early laparoscopic cholecystectomy is safe and results in a shorter hospital stay compared to late laparoscopic cholecystectomy.

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.

Submaxilitis aguda bilateral asociada con listeriosis en un paciente inmunodeprimido / Acute bilateral submaxillitis associated to listeriosis in immunosuppressed patient

Acute bilateral submaxillitis is a rare event, except when it is caused by sialolithiasis. It has been described secondary to allergic, infectious, suppurative or viral processes, autoimmune such as Sjögren's syndrome, drugs such as thiopurines, nitrofurantoin, phenylbutazone, captopril, and after upper airway procedures such as upper endoscopy, orotracheal intubation bronchoscopy and ERCP (endoscopic retrograde cholangiopancreatography for choledocholithiasis). Treatment with tumour necrosis factor-alpha (TNF-alpha) antagonist drugs is associated with an increased risk of reactivation of intracellular bacterial infections, so that listeriosis has been described in pathologies that require such treatment, such as rheumatic, dermatological and intestinal diseases, which present other comorbidities or are immunocompromised. Listeriosis mainly causes bacteremia and meningitis, when symptomatic, and infects immunosuppressed persons, where it has a lethality despite 30% antibiotherapy. We present the clinical case of a male immunosuppressed patient, secondary to a treatment with azathioprine and prednisone followed by adalimumab, for indeterminate inflammatory bowel disease, superinfected by CMV, who after eating meat contaminated by Listeria monocytogenes, suffered a picture of listeriosis bacteremia, which improved with antibiotic treatment, followed by a transient acute bilateral submaxillitis, which subsided with symptomatic treatment (oral hydration). It is the only case described in the literature, in which an immunosuppressed patient treated with adalimumab, suffers from acute bilateral submaxillitis in the context of listeriosis, caused by the mumps virus.

La submaxilitis aguda bilateral es un evento raro, salvo cuando está causada por sialolitiasis. Se la ha descrito secundaria a procesos alérgicos, infecciosos, supurativos, virales o autoinmunes como el síndrome de Sjögren; a la administración de fármacos como tiopurinas, nitrofurantoina, fenilbutazona, captopril, y tras procedimientos sobre la vía aérea superior, como endoscopia digestiva alta, broncoscopia, intubación orotraqueal y colangiopancreatografía retrógrada endoscópica por coledocolitiasis (CPRE). El tratamiento con fármacos antagonistas del factor de necrosis tumoral alfa (TNF-alfa) se asocia con riesgo acentuado de reactivación de infecciones bacterianas intracelulares, de forma que se ha descrito la listeriosis en afecciones que requieren dicho tratamiento, como enfermedades reumáticas, dermatológicas y del intestino en sujetos que presentaban otras comorbilidades o estaban inmunocomprometidos. La listeriosis provoca bacteriemia y meningitis predominantemente, cuando es sintomática, e infecta a los sujetos inmunodeprimidos, en los que, a pesar de la antibioticoterapia, tiene una letalidad del 30%. Se presenta el caso clínico de un paciente varón, inmunodeprimido, secundario a tratamiento por azatioprina y prednisona seguido de adalimumab, por enfermedad inflamatoria intestinal indeterminada, sobreinfectada por citomegalovirus, que tras la ingesta de carne contaminada por Listeria monocytogenes, sufrió un cuadro de bacteriemia por listeriosis que mejoró con tratamiento con antibióticos, seguido de submaxilitis aguda bilateral transitoria, que cedió con tratamiento sintomático (hidratación oral). Es el único caso descrito en la literatura en el que un paciente inmunodeprimido tratado con adalimumab presenta submaxilitis aguda bilateral en el contexto de la listeriosis, provocada por el virus de la parotiditis.

Ultrasonido endoscópico (USE) y colangio-pancreatografía endoscópica retrógrada (CPRE) sin fluoroscopia en el tratamiento de la coledocolitiasis durante el embarazo: reporte de 2 casos / Endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) without fluoroscopy for the treatment of choledocholithiasis during pregnancy: Report of 2 cases

Resumen La enfermedad litiásica biliar es una patología frecuente en mujeres embarazadas, y las complicaciones relacionadas con los cálculos biliares durante el embarazo pueden generar desenlaces adversos tanto en la madre como en el feto. La coledocolitiasis en el embarazo requiere de una aproximación diagnóstica adecuada y su manejo busca minimizar los riesgos de las intervenciones médicas. Se describen dos casos de mujeres embarazadas quienes presentan coledocolitiasis documentada por colangiorresonancia. Se realizó el tratamiento con la combinación de ultrasonido endoscópico (USE) y colangiopancreatografía endoscópica retrógrada (CPRE) sin fluoroscopia, con lo cual se logró resolver la coledocolitiasis sin exponer al feto a radiación ionizante, se confirmó la permeabilización del colédoco y se observó una adecuada evolución posoperatoria tanto materna como fetal.

Abstract Biliary lithiasis is a common condition in pregnant women, and complications related to gallstones during pregnancy can lead to adverse outcomes in both the mother and the fetus. Choledocholithiasis during pregnancy requires an adequate diagnostic approach to minimize the risks of medical interventions. The following are two cases of pregnant women with choledocholithiasis diagnosed using magnetic resonance cholangiography. Treatment included a combination of endoscopic ultrasound and retrograde endoscopic cholangiopancreatography (ERCP) without fluoroscopy, achieving the resolution of choledocholithiasis, without exposing the fetus to ionizing radiation, confirming the permeabilization of the common bile duct, and observing an adequate postoperative evolution of both the mother and the fetus.

Colecistectomía y trasplante cardíaco / Cholecystectomy and heart transplantation

RESUMEN Antecedentes: los avances en cuidados perioperatorios e inmunosupresión permitieron que la su pervivencia de los pacientes trasplantados aumente significativamente, así observamos que la litiasis vesicular es más frecuente en este grupo de pacientes. Objetivo: el objetivo de este trabajo es analizar y describir los resultados obtenidos en colecistecto mías en pacientes trasplantados cardíacos. Material y métodos: seleccionamos los pacientes mediante una búsqueda cruzada entre las bases de datos de Trasplante Cardíaco y Cirugía Biliar. Recopilamos información sobre sus antecedentes médi cos, parámetros clínicos y de laboratorio, entre otros. Resultados: entre enero 1994-diciembre 2017 se realizaron 154 trasplantes cardíacos con una edad media de 40 años; 16 pacientes fueron incluidos en este estudio y en los cuales fue realizada la cole cistectomía laparoscópica posterior al trasplante. No se registraron morbilidad, readmisiones ni mor talidad. Conclusión: la colecistectomía laparoscópica es segura y es el método de elección en pacientes tras plantados cardíacos. Se debe realizar colangiografía intraoperatoria, ya que los predictores de litiasis coledociana suelen estar alterados.

ABSTRACT Background: The advances in perioperative care and immunosuppressive treatment resulted in a significant increase in survival of transplant patients; as a result, cholelithiasis is more common in transplant patients. Objective: The aim of this study is to analyze and describe the results obtained in cholecystectomies in heart transplant patients. Material and methods: We selected patients by cross-referencing the databases of heart transplantation and scheduled biliary surgeries, and collected information on their medical history, clinical parameters and laboratory tests, among other data. Results: Between January 1994 and December 2017, 154 heart transplant procedures were performed; mean age was 40 years; 16 underwent laparoscopic cholecystectomy after heart transplantation and were included in this study. There were no complications, readmissions or deaths. Conclusion: Laparoscopic cholecystectomy is safe and is the method of choice for heart transplant patients with cholelithiasis. Intraoperative cholangiography should be performed as the predictors of choledocholithiasis are usually abnormal.

Hematoma subcapsular hepático pos-CPRE: reporte de caso y revisión de la literatura / Subcapsular hepatic hematoma after ERCP. Case report and literature review

Resumen Presentamos el caso de un paciente de 68 años, sin antecedentes de importancia, que por su cuadro clínico y resultados paraclínicos fue clasificado con riesgo intermedio para coledocolitiasis. En efecto, por medio de colangiorresonancia se realizó el diagnóstico confirmatorio. Fue llevado a colangiopancreatografía retrograda endoscópica en dos ocasiones -la primera fallida por papila intradiverticular-; en el segundo intento (exitoso con extracción del lito), el paciente presentó evolución posprocedimiento tórpida, con marcado dolor abdominal y anemización. Fue llevado a tomografía de abdomen con contraste, la cual confirmó el diagnóstico de hematoma subcapsular. Se decidió implementar el manejo conservador y se logró un control adecuado del sangrado.

Abstract This is the case of a 68-year-old female patient, with no relevant history, who was classified as intermediate risk for choledocholithiasis due to her symptoms and lab test results. The diagnosis was confirmed by means of cholangioresonance. She was taken to ERCP on two occasions; the first failed due to intradiverticular papilla, and during the second attempt (successful with the removal of the stone), the patient had a torpid post-procedure evolution, with marked abdominal pain and anemization. An abdominal tomography with contrast was performed, which confirmed the diagnosis of subcapsular hematoma. A conservative management was implemented, achieving adequate bleeding control.

Abordaje laparoscópico sistemático de la coledocolitiasis / Routine laparoscopic management of common bile duct stones

RESUMEN Antecedentes: la prevalencia conjunta de litiasis vesicular y coledociana aumenta con la edad y llega al 15% en la octava década de la vida. Su manejo continúa siendo controvertido: algunos profesionales prefieren el abordaje en un tiempo por videolaparoscopia, y otros, el abordaje en dos tiempos con endoscopia (CPRE preoperatoria) seguida de colecistectomía laparoscópica. Objetivo: evaluar la eficacia y seguridad del manejo en un tiempo por videolaparoscopia en pacientes consecutivos con diagnóstico de litiasis vesicular y coledociana. Material y métodos: estudio retrospectivo con datos de una base de datos prospectiva, entre julio de 2008 y julio de 2018. Resultados: sobre un total de 2447 colecistectomías laparoscópicas realizadas en el citado período, 416 (17%) presentaron litiasis coledociana. El éxito global de la vía transcística en la extracción de litiasis coledociana fue del 81,2%: del 70,4% en los casos con diagnóstico prequirúrgico de colestasis extrahepática litiásica y del 92,9% en los otros diagnósticos. La morbilidad fue del 4%, sin mortalidad ni lesiones quirúrgicas de la vía biliar. Conclusión : el manejo en un tiempo por videolaparoscopia es eficaz y seguro debido al elevado éxito global de la instrumentación transcística (ITC). El diagnóstico preoperatorio de coledocolitiasis condi ciona una disminución de esa eficacia, por mayor indicación de coledocotomía, con un aumento de la morbilidad y del tiempo de internación.

ABSTRACT Background: The prevalence of common bile duct stones associated with cholelithiasis increases with age and is about 15 % in the 8th decade of life but its management is still controversial. Some surgeons prefer the single-stage approach with laparoscopy while others suggest the two-stage management with preoperative endoscopic retrograde cholangiopancreatography (ERCP) followed by laparoscopic cholecystectomy. Objective: The aim of the present study was to evaluate the efficacy of feasibility of single-stage laparoscopic surgery in patients with cholelithiasis and choledocholithiasis. Material and methods: We conducted a retrospective study with prospectively collected data between July 2008 and July 2018. Results: Of 2447 laparoscopic cholecystectomies performed during the study period, 416 presented common bile duct stones. The global success of the transcystic approach to clear common bile duct stones was 81.2%, 70.4% in the cases with preoperative diagnosis of choledocholithiasis and 92.9% for other diagnoses. The rate of complications was 4% without deaths or bile duct injuries. Conclusion: Single-stage laparoscopic surgery is an efficient and safe approach based on the high global success of transcystic exploration. The preoperative diagnosis of choledocholithiasis reduces the efficacy of the procedure due to greater indication of choledocotomy, with complications and longer length of hospital stay.
