The clinical value of intraoperative nasobiliary tube placement with gastroscope in primary suture after choledochotomy

Abstract

Objective To evaluate the clinical value of intraoperative placement of nasobiliary tube with gastroscope in primary suture after choleduchotomy.Methods A case-control study was performed on 42 patients undergoing this procedure and 40 patients receiving choledochotomy T-tube drainage after surgery in a same period of time.All cases entered according tO the inclusion criteria were verified to be free of retained stones,stricture or obstruction of common bile duct.Abdominal drainage tubes were placed as usual.Results No bile leakage was found in any of the 42 patients receiving the new procedure with a SUCCESS rate of 97.6%(41/42).The number of days taken to extubate intra-choledochus drainage tubes and the length of the postoperative hospital stay were both significantly reduced in the nasobiliary tube drainage patients compared with T-tube drainage controls (P＜0.05).The major adverse effect,if any,was minor discomfort in the pharynx nasalis.Conclusions Intraoperative nasobiliary tube placement is effective in prevention of bile leakage and bile duet stricture in primary suture after choledochotomy.This uncomplicated procedure is safe and reliable with promising clinical application.
