ABSTRACT

A choledochoduodenal fistula is an abnormal connection between the common bile duct and the duodenum, which are associated with a history of problems in the common bile duct. It has appeared in 0.74% of patients submitted for biliary tract surgery. The most frequent symptoms of non-obstructive enteric biliary fistulas are: epigastric pain, cholangitis (80.91%), jaundice (54,.26%), fever (50.69%), nausea and/or vomiting (10.30%), abdominal distension (0.39%), asymptomatic (0.11%), and diarrhea (0.11%). Diagnostic imaging methods provide the data of greatest interest in revealing the presence of air in the bile duct. This method, as well as barium reflux under the biliary tree in contrasted studies and in ERCP, reveal the fistulous tract and its location. Neither the prevalence, nor the clinical characteristics that pertain to its presentation, are well known among our population. Possible treatments for this illness include conservative treatment with medication, endoscopic sphincterotomy, and surgical therapy.

ABSTRACT

RESUMEN Objetivos: El acceso biliar refractario a las técnicas convencionales de canulación es un escenario clínico desafiante para la mayoría de endoscopistas, la técnica de rendezvous endoscópico-percutáneo es una óptima alternativa con altas tasas de éxito y bajas tasas de complicaciones en manos expertas, sin embargo, su uso rutinario en Occidente principalmente Latinoamérica es aún limitado. El objetivo de nuestro estudio fue evaluar la factibilidad, eficacia y seguridad del rendezvous endoscópico-percutáneo en el manejo de la vía biliar difícil en un centro endoscópico en Perú. Materiales y métodos: Estudio descriptivo - tipo serie de casos que incluyó 21 pacientes, con diagnóstico de vía biliar difícil, todos tratados mediante rendezvous endoscópico-percutáneo entre Julio 2017 a Julio 2020. Se evaluó: edad, género, número de colangiopancreatografias retrógradas endoscópicas fallidas previas, hallazgos endoscópicos asociados, tasa de canulación exitosa, tasa de resolución exitosa de coledocolitiasis difícil, eventos adversos y mortalidad relacionada con el procedimiento. Resultados: La tasa de canulación exitosa fue del 100% (21/21). Se presentaron 12 casos (57,1%) de coledocolitiasis difícil de los cuales se obtuvo una tasa de resolución exitosa del 91,6% (11/12). La tasa global de eventos adversos fue de 4,7% (1/21), la cual fue un caso de hemorragia digestiva post-esfinteroplastía que fue resuelta exitosamente solo por vía endoscópica. Conclusiones: El rendezvous endoscópico-percutáneo realizado por manos expertas es factible, seguro y clínicamente efectivo para el manejo de la vía biliar difícil en Latinoamérica.


ABSTRACT Objectives: Biliary access refractory to conventional cannulation techniques is a challenging clinical scenario for most endoscopists. The endoscopic-percutaneous rendezvous technique is an optimal alternative with high success rates and low complication rates in expert hands, however its routine use in the West, mainly in Latin America, is still limited. The aim of our study was to evaluate the feasibility, efficacy and safety of endoscopic-percutaneous rendezvous in the management of difficult biliary tract in an endoscopic center in Peru. Materials and methods: Descriptive study - case series type that included 21 patients, with diagnosis of difficult bile duct, all treated by endoscopic-percutaneous rendezvous between July 2017 to July 2020. We evaluated: age, gender, number of previous failed endoscopic retrograde cholangiopancreatography, associated endoscopic findings, rate of successful cannulation, rate of successful resolution of difficult choledocholithiasis, adverse events and procedure-related mortality. Results: The rate of successful cannulation was 100% (21/21). There were 12 cases (57.1%) of difficult choledocholithiasis of which there was a successful resolution rate of 91.6% (11/12). The overall adverse event rate was 4.7% (1/21), which was one case of post-sphincteroplasty gastrointestinal bleeding that was successfully resolved endoscopically only. Conclusions: Endoscopic-percutaneous rendezvous performed by expert hands is feasible, safe and clinically effective for the management of the difficult bile duct in Latin America.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

The process of endoscopic retrograde cholangiopancreatography (ERCP) is inva-sive, and its related treatments have a potential risk of complications, which poses certain obstacles to its safe promotion. Therefore, it is very important to standardize the management of ERCP compli-cations and promote the widespread development of ERCP in China. The authors interpret the back-ground, significance, and key issues that need to be paid attention to in the Guidelines for the management of complications of duodenal perforation associated with ERCP in China ( 2023 edition), in order to facilitate ERCP physicians to better grasp and apply the guidelines, provide guidance and reference for the standardized management of ERCP related complications of duodenal perforation, and promote the popularization and widespread development of ERCP in China.

ABSTRACT

Objective:To analyze the risk factors of biliary infection after endoscopic retrograde cholangiopancreatography (ERCP) in patients with malignant biliary obstruction.Methods:Clinical data of 160 patients with malignant biliary obstruction admitted to the Affiliated People's Hospital of Ningbo Univer-sity from June 2017 to June 2022 were retrospectively analyzed, including 89 males and 71 females, aged (65.1±8.0) (range, 41-78) years old. Patients were divided into two groups according to the occurrence of biliary infection within 30 days after ERCP: infected group ( n=30) and uninfected group ( n=130). Multivariate logistic regression was used to identify the risk factors of postoperative biliary infection. Results:The incidence of biliary infection after ERCP was 18.8% (30/160) in the patients with malignant biliary obstruction. A total of 43 strains of pathogenic bacteria were detected, including 34 Gram-negative strains and nine Gram-positive strains. The most common pathogenic bacterium was Escherichia coli. Multivariate analysis showed patients with diabetes mellitus ( OR=2.356, 95% CI: 1.587-5.441, P=0.001), sphincter dysfunction ( OR=2.651, 95% CI: 1.854-6.225, P=0.005), preoperative albumin <35 g/L ( OR=3.225, 95% CI: 2.041-5.689, P=0.002), preoperative hemoglobin <110 g/L ( OR=3.424, 95% CI: 2.115-6.333, P=0.003) suffered a higher risk of biliary infection after ERCP. Conclusion:Diabetes mellitus, sphincter dysfunction, lower levels of preoperative albumin and hemoglobin are independent risk factors for biliary infection after ERCP in patients with malignant biliary obstruction.

ABSTRACT

Objective:To juxtapose laparoscopic cholecystectomy combined with common bile duct exploration and stone extraction (LC+ LCBDE) against endoscopic retrograde cholangiopancreatography/sphincterotomy with laparoscopic cholecystectomy (LC+ ERCP/EST) in the therapeutic context of acute biliary pancreatitis.Methods:The clinical data of patients with acute biliary pancreatitis in Department of Hepatobiliary Surgery, Datong Third People's Hospital from January 2017 to January 2021 were retrospectively analyzed. A total of 44 patients were inrolled, including 23 males and 21 females, with the age of (60.6±11.7) years. Based on different treatment approaches, the patients were divided into the LC+ LCBDE group ( n=33) and the LC+ ERCP group ( n=11, LC+ ERCP/EST). Total bilirubin, direct bilirubin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood amylase, operation time, postoperative hospitalization stays, total hospitalization cost, postoperative anal exhaust time, and postoperative complications (bile leakage, fever, bleeding) were compared between the two groups. Results:There were no significant differences in preoperative total bilirubin, direct bilirubin, ALT, AST, and blood amylase between LC+ ERCP group and LC+ LCBDE groups (all P>0.05). In LC+ LCBDE group, operation time was 110.0 (96.3, 147.5) min, postoperative hospitalization time was 9.0 (7.5, 11.0) d, postoperative exhaust time was 2.0 (1.0, 2.0) d, and in LC+ LCBDE group, operation time was 60.0 (32.0, 65.0) min, postoperative hospitalization time was 7.0 (4.0, 8.0) d, postoperative exhaust time was 1.0 (1.0, 1.0) d. Comparisons with LC+ LCBDE group, LC+ ERCP group had shorter postoperative hospitalization stay and earlier postoperative exhaust time, the total hospitalization cost of LC+ LCBDE group was 23 829.3 (21 779.6, 27 221.9) yuan, which was higher than 36 894.8 (31 963.5, 41 172.2) yuan in LC+ ERCP group, and the differences were statistically significant (all P<0.05). Comparison of postoperative total bilirubin, direct bilirubin, ALT and AST between LC+ ERCP group and LC+ LCBDE group, with no significant difference(all P>0.05). No postoperative complications such as bile leakage, residual stones, fever and bleeding occurred in both groups. Conclusion:Compared with LC+ ERCP/EST, LC+ LCBDE in the treatment of acute biliary pancreatitis, although the operation time and hospital stay are longer, but the total hospitalization cost is less, there is no need for multiple operations, and it can be used as the first choice for acute biliary pancreatitis.

ABSTRACT

Objective:Quantified MRCP imaging data was used as a reference for design and preparation of a modified percutaneous transhepatic cholangio drainage (PTCD) tube.Methods:3.0 T upper abdominal MR and MRCP imaging data of 2 300 patients treated from July 2015 to July 2020 at the Department of Radiology of the Affiliated Cancer Hospital of Zhengzhou University were screened and a total of 381 patients diagnosed with biliary duct structures were identified. Causative etiologies among these patients included pancreatic adenocarcinoma (pancreatic head), cholangiocarcinoma, ampullary carcinoma, as well as intrahepatic and/or extrahepatic bile duct dilation. An improved PTCD tube was designed based on MRCP quantification of left and right hepatic and common hepatic duct length.Results:In the setting of biliary obstruction caused by malignancy, the distance of the left hepatic duct from its origin to the point of left and right hepatic duct confluence was 15.9±3.8 mm, while the distance of the right hepatic duct from its origin to the point of left and right hepatic duct confluence was 12.4±3.2 mm; the length of the bile duct from its origin to the point of left and right hepatic duct confluence was 34.0±8.1 mm. The improved PTCD tube design incorporated an altered length of the drainage orifice.Conclusion:MRCP imaging of the biliary tract is effective for measuring biliary tract length in the setting of pathological dilation. Based on our biliary tract measurements, a modified PTCD tube was designed to more effectively meet drainage requirements and manage biliary obstruction caused by Bismuth-Corlette type Ⅱ and Ⅲ malignancies.

ABSTRACT

Objective:To investigate the safety and effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis and treatment of pediatric pancreaticobiliary maljunction (PBM).Methods:Data of 40 pediatric patients under 14 with PBM diagnosed and treated by ERCP at Department of Gastroenterology, Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from November 2012 to September 2022 were collected. PBM types, ERCP-related diagnosis and treatment, adverse events and prognosis were retrospectively analyzed.Results:Nineteen cases were P-B type (joining of common bile duct with pancreatic duct), 17 were B-P type (joining of pancreatic duct with common bile duct), and 4 were complex type. Forty children with PBM underwent 50 ERCP-related operations, among which 48 procedures succeeded. One case failed during cannulation of ERCP, replaced by rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP) afterwards. There were no serious postoperative adverse events such as bleeding, perforation or death. Thirty-four patients (85%) were followed up successfully, among which 14 underwent further surgery and 20 continued conservative treatment.Conclusion:ERCP is the golden standard to diagnose pediatric PBM, and it is also safe and effective treatment for PBM.

ABSTRACT

In recent years, with the development of organ preservation, surgical techniques, perioperative management and immunosuppression regimens, the success rate of liver transplantation and survival rate of the recipients have been significantly enhanced. Liver transplantation has become the optimal treatment for patients with end-stage liver disease. However, biliary complications still commonly occur after liver transplantation, especially biliary anastomotic stricture. Severe biliary anastomotic stricture will not only increase the cost of treatment, but also lead to graft loss and even affect the survival rate of recipients. Therefore, timely diagnosis and treatment of biliary anastomotic stricture play a significant role in improving the survival rate of liver transplant recipients. In this article, the risk factors, clinical symptoms, diagnosis and treatment of biliary anastomotic stricture after liver transplantation were reviewed, aiming to provide novel ideas for the research, diagnosis and treatment of biliary anastomotic stricture after liver transplantation, and further enhance clinical efficacy of liver transplantation and the quality of life of recipients.

ABSTRACT

ObjectiveTo investigate the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in the treatment of difficult choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 12 patients with difficult choledocholithiasis who underwent ERCP and electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system in Department of Gastroenterology, Jilin People’s Hospital, from May to November 2022. The clinical effect of lithotripsy and lithotomy was observed, and postoperative complications and time of surgical operation were assessed. ResultsAmong the 12 patients, 11 (91.67%) were successfully treated by electrohydraulic lithotripsy under direct view, 9 (75.00%) achieved first-attempt success in lithotripsy, and 11 (91.67%) had complete removal of calculi; 1 patient was found to have stenosis of the bile ducts caused by multiple biliary tract surgeries, and grade Ⅱ intrahepatic bile duct stones above the sites of stenosis were removed under direct view, but there were still residues of grade Ⅲ intrahepatic bile duct stones, which led to the fact that complete calculus removal was not achieved. The mean time of ERCP operation was 91.3±26.2 minutes, including a time of 41.8±22.2 minutes for energy lithotripsy. There were 2 cases of postoperative biliary tract infection which were improved after anti-infective therapy, 2 cases of hyperamylasemia which were not given special treatment, and 3 cases of mild pancreatitis which were improved after symptomatic medication, and there were no complications such as bleeding and perforation. ConclusionERCP combined with electrohydraulic lithotripsy under the direct view of eyeMax biliary-pancreatic imaging system is safe, effective, and feasible in the treatment of difficult choledocholithiasis.

ABSTRACT

Objective To explore the utility of different endoscopic retrograde cholangiopancreatography(ERCP)complexity scales in the training of endoscopists.Methods Clinical data of 237 patients treated by ERCP completed by trainee physicians at two hospitals in Eastern China from February 2022 to February 2023 were prospectively collected.All ERCP cases were classified using previously proposed complexity grading scales,including the American Society of Gastrointestinal Endoscopy(ASGE),Morriston and HOUSE grading scales,compared with the hepatopancreatic ampulla features classification.Successful intubation,successful surgical treatment and complication rates within 48 h were recorded.Results Within each grading,subgroups were divided according to severity,and the comparison of intubation success rates between subgroups in the 3 different grades showed statistically significant differences(P = 0.000).The treatment success rate and intubation success rate had similar findings(P = 0.000).There was no correlation between the complication rate and ASGE grading(P = 0.361),Morriston grading(P = 0.332),and HOUSE grading(P = 0.586).When only cases with primitive papillae were considered,the intubation success rate depended on the complexity grading after the newly added classification of hepatopancreatic ampulla features.In the ASGE group,the success rate of intubation was compared between different subgroups,and the difference was statistically significant(P = 0.004);in the Morriston group,the success rate of intubation was compared between different subgroups,and the success rate of intubation was statistically significant(P = 0.002);in the HOUSE group,the success rate of intubation was compared between different subgroups,and the difference was statistically significant(P = 0.000);In the hepatopancreatic ampulla characteristics group,the difference in intubation success rate was statistically significant when compared between different subgroups(P = 0.000).Similar findings were also found for treatment success rate and intubation success rate(P = 0.000).There was no correlation between the complication rate and ASGE group(P = 0.586),Morriston group(P = 0.443),HOUSE group(P = 0.306),and hepatopancreatic ampulla characteristics group(P = 0.350).Conclusion The use of hepatopancreatic ampulla features as a classification of biliary cannulation complexity is feasible and could be an alternative or additional means of predicting successful biliary cannulation and surgical treatment success and could be used in the future to assess endoscopist training and learning progress and technical standards.

ABSTRACT

Objective To discuss the application effect of using a stone extractor balloon catheter to assist in crossing the anastomotic stenosis in treatment of anastomotic biliary stenosis after liver transplantation using endoscopic retrograde cholangiopancreatography(ERCP).Methods Clinical data of 48 patients who developed anastomotic biliary stenosis after liver transplantation and underwent ERCP treatment were collected.Upon unsuccessful use of a dilation catheter to cross the stricture,attempts were made to cross the anastomotic biliary stenosis by using a stone extractor balloon catheter.The success rate of the procedure was recorded,intraoperative conditions were observed,treatment outcomes and complications were analyzed.Results The main presenting symptoms in the 48 patients on admission were abdominal discomfort(32 patients),fever(7 patients),pruritus(4 patients),jaundice(3 patients),and no obvious symptoms(2 patients).Preoperative magnetic resonance cholangiopancreatography(MRCP)examination revealed isolated stricture of the anastomotic site in 35 cases,and stricture associated with stones in 13 cases.Using the stone extractor balloon catheter as a guide,guidewire crossing of the anastomotic stenosis was successful in 26 cases,resulting in a success rate of 54.17%(26/48).Through statistical analysis of the successful group and the failed group,there was a significant difference in whether the distal biliary dilatation between the two groups,and the difference was statistically significant(χ2 = 8.39,P = 0.004).In the 26 successfully treated cases,alanine transaminase(ALT),aspartate transaminase(AST),γ-glutamyl transpeptidase(γ-GT),alkaline phosphatase(ALP),and total bilirubin(TBiL)levels decreased significantly 48 hours after the procedure(P<0.05),and no serious complications occurred.Conclusion The use of a stone extractor balloon catheter significantly increases the success rate of crossing anastomotic stenosis in the treatment of anastomotic biliary stenosis after liver transplantation,especially in cases with distal dilatation of the common bile duct.This approach is safe and worth promoting.
