Ectopic right anterior inferior segmental bile duct and iatrogenic proximal bile duct injury: report of eight patients / 中华肝胆外科杂志

Objective@#To summarize our clinical experience and management of an anomalous proximal bile duct joining the cystic duct in laparoscopic cholecystectomy (LC).@*Methods@#A retrospective study was conducted on 8 patients who had an anomalous right anterior bile duct joining the cystic duct who were treated at the Hunan Provincial People's Hospital from March 2003 to January 2019.@*Results@#All the 8 patients were diagnosed to have gallstones cholecystitis on preoperative CT, MRI and abdominal ultrasound. There were no suggestions of an anomalous bile duct. A total of 6 patients underwent reoperation after LC due to abdominal pain and biliary peritonitis. These 6 patients were treated with drainage and T-tube insertion. In the other 2 patients, the anomalous bile duct opening which joined the cystic duct were detected during LC. There was one patient converted to open laparotomy with preservation of the cystic duct and underwent common bile duct T-tube drainage. The other patients continued with laparoscopic surgery. The cystic duct was partially resected with removal of gallbladder, followed by common bile duct drainage. The average follow-up period was 3.4 years and the results were satisfactory.@*Conclusions@#Biliary duct anomaly is the main cause of iatrogenic proximal bile duct injury during laparoscopic cholecystectomy. It is not uncommon to have the anomaly of insertion of right anterior segmental bile duct to the cystic duct. To avoid iatrogenic biliary tract injury, careful preoperative study of X-ray films, accurate identification of the intraoperative gallbladder triangle anatomical structures. Strict adherence to carry out the three-word procedure of " discrimination, cut, identify" will help to reduce the incidence of biliary tract complications in laparoscopic cholecystectomy.

Treatment of bile duct variation in Laparoscopic Cholecystectomy:report of 7 case / 中国基层医药

Objective To explore treatment of bile duct variation in Laparoscopic Cholecystectom.Methods The author retrospectively analyzed the clinical data of 7 cases with bile duct variation in 2 000 patients performing Laparoscopic Cholecystectomy.Among the 7 cases,2 cases had small hepatic duct openings in the gallbladder bed;2 cases had cystic duct openings in the right hepatic duct;2 cases had accessory right hepatic duct;and one case had rare variation whose right hepatic bile duct and the jejunum connect together.2 cases of the first variation had no bile leakage,adopting the suture method in LC.Among 2 cases of the second variation(all found in LC),one case had bile spillage in the junction of the cystic duct and the right hepatic duct,so the operator converses to laparotomy,cuts the gallbladder,sutures the break,and the patient had no bile leakage at last;The other one case was anatomized clearly under the cavity mirror.Among 2 cases of the third variation,one had no bile leakage,whose accessory hepatic duct was ligated in LC.The other one case had bile leakage after LC,so the operator converses to laparotomy,clips the accessory hepatic duct,and extract the drainage tube until there was no bile drainage.The last case was mistaken and cut it,the next day biliary peritonitis appeared,so the bile leakage was sewed up under the laparoscope.Results The seven cases were followed 1 ~3 years,they had no jaundice and their liver function was normal.Conclusion Careful-ly dissect Calot's triangle in LC,observe bile leakage after LC;improve the level of understanding and dealing bile duct variation in LC,don't cut the duct which is known to us.We should treat differently according to particular case.

Avoiding injuries to aberrant right posterior hepatic duct during laparoscopic cholecystectomy / 中华肝胆外科杂志

Objective To investigate how to avoid and deal with injuries to the aberrant right posterior hepatic duct during laparoscopic cholecystectomy (LC).Method We studied 1 710 patients who underwent LC in our unit from January 2011 to November 2013.There were 5 patients with right posterior hepatic duct abnormally,and this paper analysed the cases.Results In the 5 patients,one patient had the right posterior hepatic duct draining into the gallbladder body (Ⅰ A type),two patients had the right posterior hepatic duct draining into the cystic duct (ⅢA type),and two patients had the cystic duct draining into the right posterior hepatic duct (ⅢB type).There was no damage to the right posterior hepatic duct during operation.One patient was converted from LC to open operation.The major aberrance was class Ⅲ.Conclusions Variant bile duct is an important cause of bile duct injuries during LC.The right posterior hepatic duct variation is the most common form.To raise our vigilance and fully understand the types of aberrant right posterior hepatic duct,reasonable use of preoperative MRCP and intraoperative cholangiography in selected patients are fundamental.Aberrant right posterior hepatic duct injuries can effectively be avoided.

Prophylaxis and treatment of bile leakage from anormous hepatic ducts after liver transplantation / 中华肝胆外科杂志

ObjectiveTo investigate prophylaxis and treatment of bile leakage from hepatic duct anomalies after liver transplantation.MethodsWe retrospectively analyzed 3 patients with bile leakage from hepatic duct anomalies after liver transplantation in our institute.The graft procurements were combined liver-kidney harvesting.The reconstruction of the bile ducts was end-to-end anastomoses.ResultsIn the first patient with a right accessory duct joining the cystic duct,leakage of bile came from the stump of the cystic duct after anastomosis of the bile ducts.The original anastomosis was taken down,and reanastomosis was performed after plasty of the bile ducts.The patient recovered uneventfully.In the second patient with a Luschka bile duct,the biliary fistula closed spontaneously after percutaneous drainage.However,re-transplantation was performed for severe infection 7 month after the primary transplantation.In the third patient with an accessory hepatic duct from the right posterior sector joining the common bile duct,the bile duct stump which we missed leaked bile.Re-transplantation was performed because of severe complications.Conclusion Understanding the anatomy of intra- and extra-hepatic bile ducts and their common anomalies identifying the structures in the porta hepatis during preparation of the liver grafts,and looking for possible accessory hepatic ducts and aberrant bile ducts are important steps to prevent bile leakage in liver transplantation.
