Duplicación del colédoco asociado a unión biliopancreática anómala: Reporte de caso / Common bile duct duplication associated with anomalous biliopancreatic junction: A case report

Introducción. La duplicación del colédoco es una anomalía congénita poco frecuente. En la mayoría de los casos este defecto se asocia a cálculos en la vía biliar, unión pancreatobiliar anómala, pancreatitis, cáncer gástrico o colangiocarcinoma. Por esta razón, el diagnóstico y el tratamiento temprano son importantes para evitar las complicaciones descritas a futuro. Métodos. Se presenta el caso de una paciente de 30 años, con antecedente de pancreatitis aguda, con cuadro de dolor abdominal crónico, a quien se le realizaron varios estudios imagenológicos sin claro diagnóstico. Fue llevada a manejo quirúrgico en donde se documentó duplicación del colédoco tipo II con unión pancreatobiliar anómala. Resultados. Se hizo reconstrucción de las vías biliares y hepatico-yeyunostomía, con adecuada evolución postoperatoria y reporte final de patología sin evidencia de tumor. Conclusión. El diagnóstico se hace mediante ecografía endoscópica biliopancreática, colangiorresonancia o colangiopancreatografía retrógrada endoscópica. El tratamiento depende de si está asociado o no a la presencia de unión biliopancreática anómala o cáncer. Si el paciente no presenta patología neoplásica, el tratamiento quirúrgico recomendado es la resección del conducto con reconstrucción de las vías biliares.

Introduction. Double common bile duct is an extremely rare congenital anomaly. This anomaly may be associated with bile duct stones, anomalous biliopancreatic junction, pancreatitis, bile duct cancer, or gastric cancers. Thus, early diagnosis and treatment is important to avoid complications. Clinical case. We report a rare case of double common bile duct associated with an anomalous biliopancreatic junction in a 30-year-old female, with prior history of acute pancreatitis, who presented with chronic abdominal pain. She underwent several imaging studies, without clear diagnosis. She was taken to surgical management where duplication of the type II common bile duct was documented with anomalous pancreatobiliary junction. Results. Reconstruction of the bile ducts and hepatico-jejunostomy were performed, with adequate postoperative evolution and final pathology report without evidence of tumor. Conclusion. Diagnosis is usually performed by an endoscopic ultrasound, magnetic resonance cholangiopancrea-tography, or endoscopic retrograde cholangiopancreatography. Treatment depends on the presence of anomalus biliopancreatic junction or concomitant cancer. In cases without associated malignancy, resection of bile duct and biliary reconstruction is the recommended surgical treatment.

Presiones de la vía biliar en pacientes con y sin colelitiasis

Introducción: El reflujo de enzimas pancreáticas hacia la vía biliar extra-hepática y la vesícula biliar es un fenómeno anormal que tiene un rol en la litogénesis y carcinogénesis. Debido a que la presión de la vía biliar depende entre otros factores, de las presiones del esfínter de Oddi. La disfunción de éste se vería reflejada en presiones elevadas de la vía biliar en pacientes con colelitiasis. Objetivo: El objetivo de este estudio es el de medir las presiones de la vía biliar extra-hepática en pacientes con y sin colelitiasis y relacionarlas con la presencia de reflujo pancreáticobiliar. Material y Método: Se diseñó un estudio pros-pectivo de casos y controles. La muestra está constituida por todos los pacientes operados con gastrectomía total por cáncer gástrico estadios I y II durante 30 meses. La medida de resultado primaria fue establecer diferencias en las presiones de la vía biliar entre pacientes con y sin colelitiasis. Resultados: Las presiones de la vía biliar extra-hepática en pacientes con colelitiasis fueron más elevadas (16,9 mmHg) que en los pacientes sin colelitiasis (3,3 mmHg) (p < 0,0001). Estas presiones se correlacionan con la presencia de amilasa y lipasa en la bilis de la vesícula; se encontraron niveles elevados de enzimas pancreáticas en pacientes con colelitiasis (p < 0,0001). Conclusiones: Las presiones de la vía biliar en pacientes con colelitiasis fueron, significativamente, mayores comparadas con las presiones de la vía biliar en pacientes sin colelitiasis. En los pacientes con colelitiasis, la presión elevada de la vía biliar se asocia a la presencia de reflujo pancreáticobiliar.

Background: The reflux of pancreatic enzymes into the bile duct and the gallbladder is an abnormal phenomenon that plays a role in lithogenesis and carcinogenesis. Because the pressure of the common bile duct depends on the pressures of the sphincter of Oddi, its dysfunction would be reflected in an increase in the pressure of the common bile duct in patients with cholelithiasis. Aim: The objective of this study was to measure the pressures of the common bile duct in patients with and without cholelithiasis and to relate them to the presence of pancreatobiliary reflux. Material and Method: A prospective case-control study was designed. The universe was constituted by all patients undergoing total gastrectomy for gastric cancer stages I and II during 30 months. The primary outcome measure was to establish differences between common bile duct pressures in patients with and without cholelithiasis. Results: Common bile duct pressures in patients with gallstones showed a significant elevation (16.9 mmHg) compared to patients without gallstones (3.3 mm Hg) (p < 0.0001). These pressures correlated with the levels of amylase and lipase in gallbladder bile; higher levels were found in patients with gallstones compared to patients without gallstones (p < 0.0001). Conclusions: Common bile duct pressure in patients with cholelithiasis was significantly higher compared to patients without cholelithiasis leading to pancreatobiliary reflux.

Tratamiento quirúrgico inmediato en niños con perforación espontánea de la vía biliar. Experiencias de 16 años

Introducción: La perforación espontánea de los conductos biliares es una rara enfermedad caracterizada por una disrupción no traumática de la vía biliar en pacientes aparentemente sanos. Se trata de una grave situación potencialmente letal, pero diagnosticada y tratada correctamente tiene un pronóstico excelente. Objetivo: Caracterizar los principales elementos clínico-quirúrgicos expresados en una serie de 5 pacientes operados en un servicio de referencia nacional. Presentación de casos: Se presenta la experiencia con una serie de casos en 16 años en una sola institución. La afección se observó en niñas recién nacidas y lactantes con una edad media de 4 meses, y se presentó desde la clínica como una colestasis acompañada de distensión abdominal, ascitis biliar, acolia, y signos de irritación peritoneal. El 80 % de los casos se intervinieron en el hospital "William Soler", y en un caso se ejecutó el procedimiento después de una laparotomía por una posible apendicitis aguda, en otro hospital. El diagnóstico se basó en el cuadro clínico descrito, la ecografía abdominal, la paracentesis con medición del índice bilirrubina líquido ascítico/bilirrubina sérica, y la colangiografía intraoperatoria. La cirugía definitiva se realizó inmediatamente, y consistió en: lavado peritoneal, colangiografía diagnóstica, reparación hepaticoyeyunostomía en Y de Roux y colocación de drenaje. Conclusiones: El tratamiento realizado resulta eficaz y seguro en todos los casos, con una excelente evolución, sin complicaciones importantes y con una total supervivencia posoperatoria. La colangiografía intraoperatoria permitió identificar el sitio de la perforación y diagnosticar malformaciones asociadas como dilataciones biliares congénitas y anomalías de la unión bilio-pancreática.

Introduction: Spontaneous bile duct perforation is a rare condition characterized by non-traumatic disruption of the bile duct in apparently healthy patients. It is a serious potentially lethal situation, but correctly diagnosed and treated its prognosis is excellent. Objetive: To characterize the main clinical-surgical elements expressed in a series of 5 patients operated in a national referral service. Case presentation: The experience with a series of cases during a period of 16 years in a single institution is presented. The condition was observed mainly in newborn girls and infants with an average age of 4 months, and presented clinically as cholestasis accompanied by abdominal distension, biliary ascites, acholia, and signs of peritoneal irritation. 80% of the cases were operated primarily in the "William Soler" hospital, and in one case the procedure was performed after a laparotomy for a possible acute appendicitis, in another hospital. The diagnosis was based on the clinical picture described, abdominal ultrasound, paracentesis with measurement of the ascitic liquid bilirubin/serum bilirubin index, and intraoperative cholangiography. Definitive surgery was performed immediately and consisted of: peritoneal lavage, diagnostic cholangiography, Roux-en-Y liver and jejunostomy repair and drainage placement. Conclusions: The treatment performed was effective and safe in all cases, with an excellent evolution, no major complications and total postoperative survival. Intraoperative cholangiography made it possible to identify the site of perforation and to diagnose associated malformations such as congenital biliary dilatations and anomalies of the biliary-pancreatic junction.

Resección laparoscópica de dilatación quística congénita del conducto cístico en un paciente pediátrico

Introducción: La dilatación quística congénita del conducto cístico o dilatación tipo VI de la clasificación de Todani, es una variante rara de dilatación congénita de la vía biliar. Objetivo: Explicar la metodología diagnóstica y terapéutica empleada en un caso pediátrico con esta entidad, y destacar la ventaja de su tratamiento oportuno por vía mínimamente invasiva. Presentación del caso: Paciente masculino de 6 años con sintomatología sugestiva de enfermedad vesicular, referido desde la atención secundaria por sospecha de quiste de colédoco. En el ultrasonido se detectaba una lesión ecolúcida adyacente a la vesícula biliar, sin dilatación de las vías biliares intrahepáticas. Se realizó colangiografía laparoscópica y se confirmó una dilatación quística aislada del conducto cístico, la cual se resecó por vía laparoscópica, igualmente. Conclusiones: La incidencia de la dilatación quística del conducto cístico es muy baja y se puede presentar en niños con sintomatología variable. El diagnóstico generalmente es tardío, puede sospecharse mediante la ecografía abdominal y confirmarse con la colangiografía laparoscópica, aun en ausencia de otros medios diagnósticos más modernos. Su reconocimiento y correcta clasificación permiten realizar el tratamiento quirúrgico definitivo exitosamente, de preferencia por vía laparoscópica.

Introduction: Congenital cystic duct dilatation, or Todani classification type VI dilatation, is a rare variant of congenital bile duct dilatation. Objective: To explain the diagnostic and therapeutic methodology used in a pediatric case with this entity, and to highlight the advantage of its timely minimally invasive treatment. Case presentation: Six-year-old male patient with symptoms suggestive of gallbladder disease, referred from secondary care for suspicion of a common bile duct cyst. Ultrasound showed an echolucent lesion adjacent to the gallbladder, without dilatation of the intrahepatic bile ducts. Laparoscopic cholangiography was performed and confirmed an isolated cystic dilatation of the cystic duct, which was resected laparoscopically, likewise. Conclusions: The incidence of cystic dilatation of the cystic duct is very low and may present in children with variable symptomatology. Diagnosis is usually late, can be suspected by abdominal ultrasound and confirmed by laparoscopic cholangiography, even in the absence of other more modern diagnostic tools. Its recognition and correct classification permit a successful definitive surgical treatment, preferably laparoscopically.

Laparoscopic cholecystectomy combined with normal-sized common bile duct exploration for cholecystolithiasis and choledocholithiasis / 中华普通外科杂志

Objective:To evaluate laparoscopic choledocholithotomy in patients with cholecystolithiasis and normal sized common bile duct(CBD) with choledocholithiasis.Methods:The clinical data of 393 patients with cholecystolithiasis and choledocholithiasis treated by LC combined with LCBDE at the Department of General Surgery of Hefei Second People's Hospital from Mar 2014 to Jul 2021 were retrospectively analyzed.Results:There were 280 CBD calculi cases in which CBD diameter >8 mm which was included into CBD dilated group, and 113 cases of CBD calculi with normal diameter (5 mm≤CBD diameter ≤8 mm). There was no difference in operative time and postoperative complications in the small diameter group. During the follow-up period, 1 case in the dilated group experienced biliary tract stenosis and treated by stenting. There was no statistical significance in biliary tract stenosis in both groups ( P>0.05).Stone recurrence occurred in 3 cases (2.7%) in the normal diameter group, all of which were removed by ERCP lithotomy. Stone recurrence occurred in 8 cases (2.9%) in the CBD dilated group, 7 were removed by ERCP stone extraction and 1 refused further treatment. Conclusion:It is safe and feasible to perform LC+LCBDE in patients with cholecystolithiasis complicating normal sized CBD stones.

Analysis of 17 cases of Vaterian system adenomyomatous hyperplasia / 中华肝胆外科杂志

Objective:To study the features of adenomyomatous hyperplasia (AH) of the Vaterian system (common bile duct and ampulla of Vater) to help in the diagnosis and management of this disease.Methods:A retrospective analysis on the data of 17 patients who had a postoperative pathological diagnosis of AH of the Vaterian system treated from January 2005 to December 2021 at the First Medical Center of the PLA General Hospital was carried out with 12 males and 5 females, aged (58.4±11.3) years. The clinical presentations, treatment and postoperative pathology of these patients were analyzed. Patients with dysplasia of the tubular mucosal epithelium in the non-cancerous area around the AH under microscopy were included in the AH with dysplasia group ( n=8), and those without dysplasia were included in the control group ( n=9). The clinical characteristics of the two groups were compared. Results:The main clinical symptoms were abdominal pain in 8 patients, jaundice in 7 patients and fever in 2 patients. Preoperative imaging showed 10 cases of occupying lesions and 6 cases of abnormally dilated intrahepatic and extrahepatic bile ducts without obvious lesions or stones or biliary tract injury stenosis. Sixteen patients underwent radical pancreaticoduodenectomy, and 1 patient underwent extrahepatic biliary resection combined with choledochojejunostomy for bile duct obstruction due to biliary stones, 3 patients had combined malignant tumors, 1 patient had a carcinoma of AH origin at the ampulla of Vater, and the other 2 patients had neoplastic lesions in the mucosal epithelium adjacent to the AH (cholangiocarcinoma and ampullary carcinoma, respectively). There were no significant differences in age, gender, bile duct stones, cholangitis, combined carcinoma and liver function indexes between the two groups of patients with AH of the Vaterian system (all P>0.05). Conclusion:Adenomyomatous hyperplasia of the Vaterian system was difficult to distinguish preoperatively from malignant tumors basing on its clinical presentations or imaging findings. Such patients are recommended to be treated surgically.

A Comparative Study of Common Bile Duct Drainage by T-tube and Choledochoduodenostomy in Cases of Common Bile Duct Stones

To study and compare the cases of ‘T’-tube drainage and Choledochoduodenostomy done for Common Bile Duct stones. Methods : A prospective study was conducted from October 2019 – September 2021 (24 months including followup period) in patients diagnosed to have Choledocholithiasis in MGM Medical College and Hospital, Kishanganj, Total 50 patients were Included in this study. Those patients in whom CBD stones detected incidentally on investigation like Ultrasonography upper abdomen done for chronic calculus cholecystitis or detected during surgery for cholecystectomy ie, asymptomatic stones were also included in this study. Results : In the cases of our study, most of the patients (62%) didn’t has sludge. Choledochoduodenostomy was more frequently performed when sludge was present (P=0.043), whereas ‘T’-tube drainage was performed when sludge was absent. only 19 cases (38%) had sludge. And also it was present more commonly with larger diameter CBD (P value =0.016). Conclusion : In this study, both the surgical procedures did not produce any mortality. Some patients developed complications. This could be because much of the study population was elderly and most of the complications were noted in patient with acute cholangitis. In both the group, wound infection was noted to be most common complication. All of the patients treated conservatively successfully.

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.

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.

Internal drainage tube versus T tube in laparoscopic common bile duct exploration / 中华肝胆外科杂志

Objective:To study the effect of internal drainage tube and T tube in laparoscopic common bile duct exploration.Methods:The data of 103 patients who underwent laparoscopic common bile duct exploration for the treatment of choledocholithiasis from January 2016 to April 2021 in Dongguan Kanghua Hospital were analyzed, including 50 males and 53 females, aged (50.3±17.2) years old, the age range was 15 to 90 years old. A total of 103 patients were randomly divided into T tube group ( n=60), who received laparoscopic cholecystectomy + choledocholithotomy and stone removal+ T tube drainage, and self-dropping stent group ( n=43), who received laparoscopic cholecystectomy + choledocholithotomy and stone removal + placed with self-dropping stent. The operation time, intraoperative blood loss, postoperative drainage, postoperative hospital stay and incidence of postoperative complications were compared between the two groups. Results:The operation time of self-dropping stent group was (107.2±26.1) min, intraoperative blood loss 10(5, 10) ml, and postoperative hospital stay (6.5±3.5) d, which were better than those of T tube group (143.5±52.7) min, 10(10, 20) ml, (8.8±3.8) d, the differences were statistically significant (both P<0.05). There were no significant difference in postoperative drainage volume and postoperative complications between the two groups (both P>0.05). Conclusion:The internal drainage tube in laparoscopic common bile duct exploration is a safe and reliable surgical method for the treatment of choledocholithiasis, which can significantly shorten the hospitalization time of patients.

Advances in the pathogenesis of pancreaticobiliary maljunction / 中华肝胆外科杂志

Pancreaticobiliary maljunction means the common bile duct and the main pancreatic duct in the duodenal wall, or is the formation of a long common channel leading to biliopancreatic reflux, resulting a series of biliopancreatic diseases, and even the occurrence of biliary malignancy. The pathogenesis of pancreaticobiliary maljunction is complex, involving biliary fluid dynamics, the activation of phospholipase A2, protease activation, amino acids, fat metabolism, gene mutation. This paper summarized the latest study of the pathogenesis of the pancreaticobiliary maljunction to let clinicians understand pancreaticobiliary maljunction diseases, and provide new treatment ideas.

Clinical effect of laparoscopic common bile duct exploration through micro-incision of cystic duct and its junction in for choledocholithiasis / 国际外科学杂志

Objective:To investigate the clinical effect of laparoscopic common bile duct exploration through Micro-incision of cystic duct and its junction in for choledocholithiasis.Methods:The clinical data of 62 patients with cholecystolithiasis complicated with choledocholithiasis treated in the Department of hepatobiliary and pancreatic surgery of Huangshi Central Hospital, Edong Healthcare Group from January 2017 to December 2021 were analyzed retrospectively, and were divided into two groups according to different treatment schemes. Among them, 32 cases underwent laparoscopic cholecystectomy, common bile duct exploration and lithotomy (primary suture group), Laparoscopic choledocholithotomy and exploration + T-tube drainage (T-tube Drainage Group) 30 cases. The general data, operation time, intraoperative bleeding, postoperative exhaust time, first time out of bed, postoperative hospital stay, 24-hour postoperative pain score and the incidence of total complications were compared between the two groups.Results:The operation was successfully performed in both groups, there was no perioperative death.There was no significant difference in general data, operation time, intraoperative bleeding and the incidence of total complications between the two groups ( P> 0.05), the postoperative anal exhaust time, the first time out of bed and the postoperative hospital stay in the primary suture group were (20.3±5.8) h, (15.5±4.3) h and (4.5±1.7) d, respectively, which were significantly shorter than those in the T-tube drainage group (28.3±7.9) h, (22.8±6.7) h and (7.0±2.8) d( P<0.05); The hospitalization cost in the primary suture group was (18 725.9±855.8) yuan, which was significantly lower than that in the T-tube drainage group (23 450.7±975.4) yuan ( P< 0.05). The 24-hour pain score (2.7±0.9) scores in the primary suture group was significantly lower than that in the T-tube drainage group (3.8±1.2) scores ( P< 0.05). Conclusion:Laparoscopic common bile duct exploration through micro-incision of cystic duct and its junction is safe and effective, which can accelerate the rehabilitation of patients and reduce the cost of hospitalization, which is more in line with the concept of ERAS.

Hemofilia paraneoplásica adquirida secundaria a adenocarcinoma de la ampolla de Vater / Acquired paraneoplastic hemophilia secondary to Vater's ampulla adenocarcinoma

Resumen La hemofilia adquirida A es un desorden hemorrágico inusual de origen autoinmune que resulta en la formación de autoanticuerpos dirigidos contra el factor VIII de la coagulación. Estos autoanticuer pos pueden actuar neutralizando parcial o completamente la activación o función del factor, o también pueden acelerar su eliminación de la circulación. La incidencia mundial de la enfermedad es de 1.5 casos por millón de habitantes por año. En cerca del 50% de los pacientes se puede detectar una enfermedad subyacente que se presume responsable de la producción de los autoanticuerpos. Se presenta el caso de un varón con hemofilia adquirida A, en contexto de adenocarcinoma de la ampolla de Vater.

Abstract Acquired hemophilia A is an unusual bleeding disorder of autoimmune origin resulting in the formation of autoantibodies directed against coagulation factor VIII. These autoantibodies can act by partially or completely neutralizing the activation or function of the factor, or they can also accelerate its elimination from the circulation. The global incidence of the disease is 1.5 cases per million inhabitants per year. In nearly 50% of cases, an underlying disease that is presumed responsible to produce autoantibodies can be detected. We report a case with acquired hemophilia A, in a patient with Vater's ampulla adenocarcinoma.

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.

Coledocolitiasis y exploración laparoscópica dela vía biliar. Un estudio de cohorte / Choledocholithiasis and laparoscopic exploration of the bile duct. A cohort study

Introducción. La coledocolitiasis es la presencia de cálculos en las vías biliares. En la mayoría de los casos se trata mediante la colangio pancreatografía retrógrada endoscópica y menos comúnmente por intervención quirúrgica laparoscópica. El objetivo de este estudio fue describir una cohorte retrospectiva de pacientes sometidos a exploración laparoscópica de la vía biliar. Métodos. Se incluyeron pacientes intervenidos entre los años 2014 y 2018, en dos instituciones de nivel III en Cali, Colombia, referidos para valoración por cirugía hepatobiliar, por dificultad para la extracción de los cálculos por colangio pancreatografia retrograda endoscópica, debido al tamaño, la cantidad, o la dificultad para identificar o canular la papila duodenal. Resultados. De los 100 pacientes incluidos, se encontró que el 72 % fueron mujeres, con rango de edad entre 14 y 92 años. Al 39 % de los pacientes se les extrajo un solo cálculo y al 16 % 10 cálculos. Un 12 % presentaron cálculos gigantes (mayores de 2,5 cm de ancho) y un 44 % presentaron litiasis múltiple. Al 69 % de los pacientes se les realizó colecistectomía. El porcentaje de éxito de limpieza de la vía biliar por laparoscopia fue del 95 %.Discusión. La exploración laparoscópica de la vía biliar es una técnica posible, reproducible, segura y con excelentes resultados para el manejo de la coledocolitiasis

Introduction. Choledocholithiasis is the presence of stones in the bile ducts. In most cases it is treated by endoscopic retrograde cholangio pancreatography and less commonly by laparoscopic surgery. The objective of this study was to describe a retrospective cohort of patients who underwent laparoscopic exploration of the bile duct.Methods. The study included patients operated between 2014 and 2018, in two level III institutions in Cali, Colombia, referred for evaluation for hepato-biliary surgery, due to difficulty in removing stones by endoscopic retrograde pancreatography cholangiography, due to the size, quantity, or difficulty of identifying or cannulating the duodenal papilla. Results. Out of the 100 patients included, it was found that 72% were women, with an age range between 14 and 92 years. A single stone was removed from 39% of patients and 10 stones from 16%; 12% had giant stones (greater than 2.5 cm wide), and 44% had multiple stones; 69% of the patients underwent cholecystectomy. Laparoscopic bile duct cleaning success rate was 95%. Discussion. Laparoscopic exploration of the bile duct is a possible, reproducible, and a safe technique with excellent results for the management of choledocholithiasis

Colecistectomía segura: ¿Qué es y cómo hacerla? ¿Cómo lo hacemos nosotros? / Safe cholecystectomy: What is it and how to do it? How do we do it?

La colecistectomía laparoscópica es uno de los procedimientos más realizados a nivel mundial. La técnica laparoscópica se considera el estándar de oro para la resolución de la patología de la vesícula biliar secundaria a litiasis, y aunque es un procedimiento seguro, no se encuentra exenta de complicaciones. La complicación más grave es la lesión de la vía biliar, que, aunque es poco frecuente, con una incidencia de 0,2 a 0,4%, conduce a una disminución en la calidad de vida y contribuye a un aumento en la morbi-mortalidad. El objetivo de este artículo es reportar nuestra técnica quirúrgica, enfatizando los principios del programa de cultura para una colecistectomía segura, propuesta y descrita por the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), para minimizar los riesgos y obtener un resultado quirúrgico satisfactorio

Laparoscopic cholecystectomy is one of the most performed procedures worldwide. The laparoscopic technique is considered the gold standard for the resolution of gallbladder pathology secondary to lithiasis, and although it is a safe procedure, it is not without complications. The most serious complication is the injury to the bile duct, which, although rare, with an incidence of 0.2% to 0.4%, leads to a decrease in quality of life and contributes to an increase in morbidity and mortality. The objective of this article is to report our surgical technique, emphaszing the principles of the program for a safe cholecystectomy, proposed and described by the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), to minimize the risks and obtain a satisfactory surgical result
