Intraoperativeinternal stenting for preventing biliary anastomotic complications of liver transplantation / 中华器官移植杂志

ABSTRACT

Objective:To explore the role of internal stenting for preventing biliary anastomotic complications during complex duct-to-duct biliary reconstruction of orthotopic liver transplantation.Methods:From December 1, 2018 to April 30, 2020, intraductal stent was placed in 6 cases of complex biliary tract reconstruction during liver transplantation. Postoperative prognosis, recovery of bilirubin and biliary enzymes, management of intraductal stent and occurrence of postoperative biliary complications were observed.Results:All of them recovered and were discharged smoothly and bilirubin and biliary enzymes normalized before discharge. The average peak values of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase were 83.8±56.4 μmol/L, 151.5±76.3 U/L, 301.7±177.0 U/L and 98.4±80.9 μmol/L and the average turning points of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase 2.3±1.0, 3.0±1.1, 3.8±1.2 and 1.8±0.8 days; average time of complete recovery of total bilirubin, alkaline phosphatase, total bile acid and γ-glutamyl transpeptidase 7.7±5.1, 5.0±4.9, 23.5±7.6 and 3.8±2.4 days respectively. Intraductal stent was removed by gastroduodenoscopy ( n=3) and slipped off ( n=3). Except for one case of asymptomatic anastomotic stricture at 1 year post-operation, no biliary complications occurred during follow-ups. Conclusions:The placement of intraductal stent during complex biliary reconstruction of liver transplantation can effectively promote the recovery of postoperative liver function, enhance the quality-of-life of patients, effectively avoid the occurrence of biliary anastomotic complications and ensure the safety of patients.
