Long-term postoperative outcomes of Roux-en-Y cholangiojejunostomy in patients with benign biliary stricture.

BACKGROUND: Although there are common postoperative complications, Roux-en-Y cholangiojejunostomy is still broadly used as a standard surgical procedure for patients with biliary stricture. This study aimed to explore long-term risk factors of cholangiojejunostomy in patients with biliary stricture who underwent revisional cholangiojejunostomy. METHODS: Clinical data of 61 patients with biliary stricture undergoing revisional cholangiojejunostomy were retrospectively analyzed. These patients were classified into two groups (patients with traumatic biliary stricture and non-traumatic biliary stricture). Postoperative complications and survival time were successfully followed up. RESULTS: Among the patients, 34 underwent revisional cholangiojejunostomy due to traumatic biliary stricture, and 27 underwent revisional cholangiojejunostomy due to non-traumatic biliary surgery. Although there was no statistical difference in most clinical data between two groups, biliary dilation or not during the first surgery, cholelithiasis or not during the first surgery, long-term complications after first surgery, cholelithiasis or not during the second surgery, identifying abnormalities during the second surgery and long-term complications after second surgery were significantly different. All patients were successfully followed up and average follow-up time for patients with traumatic and non-traumatic biliary stricture was (88.44 ± 35.67) months and (69.48 ± 36.61) months respectively. Survival analysis indicated that there was no statistical difference in overall survival between two groups. Additionally, cox proportional hazard analysis demonstrated that first preoperative bilirubin level, short-term complication after first surgery and identifying abnormalities during the second surgery were independent risk factors that may have significant effects on patients' overall survival and long-term prognosis after cholangiojejunostomy. Among the intraoperative abnormal findings, residual lesions after the first operation had significant effects on the patients overall survival in the earlier stage. Relatively, anastomotic stoma stricture and biliary output loop problems had obvious effects on patients' overall survival at later stages. CONCLUSION: First preoperative bilirubin level, short-term complication after first surgery and abnormal findings during the second surgery were independent risk factors of revisional cholangiojejunostomy, which may affect patients' long-term survival. Therefore, surgeons should minimize incidence of postoperative complications through fully evaluating optimal operative time and standardizing surgical procedures.

Diagnosis and treatment modalities of hilar biliary duct stricture in hepatic cystic echinococcosis after endocystectomy.

AIM: Hilar biliary duct stricture may occur in hepatic cystic echinococcosis (CE) patients after endocystectomy. This study aimed to explore diagnosis and treatment modalities. METHODS: Clinical data of 26 hepatic CE patients undergoing endocystectomy who developed postoperative hilar biliary duct stricture were retrospectively analyzed and were classified into three types: type A, type B, and type C. Postoperative complications and survival time were successfully followed up. RESULTS: Imaging showed biliary duct stenosis, atrophy of ipsilateral hepatic lobe, reactive hyperplasia, hepatic hilum calcification, and dilation or discontinuity of intrahepatic biliary duct. All patients received partial hepatectomy to resect residual cyst cavity and atrophic liver tissue, and anastomosis of hepatic duct with jejunum or common bile duct exploration was applied to handle hilar biliary duct stricture. Twenty-five patients were successfully followed up. Among type A patients, one patient died of organ failure, and upper gastrointestinal bleeding and liver abscess occurred in one patient. Moreover, calculus of intrahepatic duct was found in one type B and type C patient. CONCLUSION: Long-term biliary fistula, infection of residual cavity or obstructive jaundice in hepatic CE patients after endocystectomy are possible indicators of hilar bile duct stricture. Individualized and comprehensive treatment measures, especially effective treatment of residual cavity and biliary fistula, are optimal to avoid serious hilar bile duct stricture.

TITLE: Diagnostic et modalités de traitement de la sténose du canal biliaire hilaire dans l'échinococcose kystique hépatique après endocystectomie. ABSTRACT: Objectif : une sténose du canal biliaire hilaire peut survenir chez les patients atteints d'échinococcose kystique (EK) hépatique après une endocystectomie. Cette étude visait à explorer les modalités de diagnostic et de traitement. Méthodes : Les données cliniques de 26 patients atteints de EK hépatique subissant une endocystectomie et ayant subi une sténose du canal biliaire hilaire postopératoire ont été analysées rétrospectivement, et ont été classées en trois types (type A, type B, type C). Les complications postopératoires et le temps de survie ont été suivis avec succès. Résultats : L'imagerie a montré une sténose du canal biliaire, une atrophie du lobe hépatique homolatéral, une hyperplasie réactive, une calcification du hile hépatique, une dilatation ou une discontinuité du canal biliaire intrahépatique. Tous les patients ont subi une hépatectomie partielle pour réséquer la cavité kystique résiduelle et le tissu hépatique atrophique, et une anastomose du canal hépatique avec le jéjunum ou une exploration du canal cholédoque a été appliquée pour traiter la sténose du canal biliaire hilaire. Vingt-cinq patients ont été suivis avec succès. Parmi les patients de type A, un patient est décédé d'une insuffisance organique et un saignement gastro-intestinal supérieur et un abcès hépatique sont survenus chez un patient. De plus, un calcul du canal intrahépatique a été trouvé chez un patient de type B et de type C. Conclusion : Une fistule biliaire à long terme, une infection de la cavité résiduelle ou une jaunisse obstructive chez les patients atteints d'EK hépatique après endocystectomie sont des indicateurs possibles de sténose du canal biliaire hilaire. Des mesures de traitement individualisées et complètes, en particulier un traitement efficace de la cavité résiduelle et de la fistule biliaire, sont optimales pour éviter une sténose grave des voies biliaires hilaires.
