Study on the primary closure of bile duct incision of laparoscopic bile duct exploration and balloon dilatation catheter dilatation / 中华消化内镜杂志

ABSTRACT

Objective To discuss the indications and complications of primary closure of bile duct incision in laparoscopic bile duct exploration and balloon dilatation catheter dilatation to treat the papillary stenosis and the intrahepatic bile duct stenosis. Methods A pospective study of 42 ptients of bile duct incision closure primary in laparoscopic bile duct exploration and balloon dilatation catheter dilatation, laparoscopic bile duct exploration and extraction of bile duct stones with choledochotomy was first adopted in order to clear the stones, then followed by the balloon dilatation catheter(explosive pressure reached 2020 kPa, used 505kPa) to dilate the papillary stenosis and the intrahepatic bile duct stenosis (CT-7542～ CT-75104) until the stenosis was released. Whether the primary closure of duct incision was selected or not, it was based on the situation of intraoperative choledochoscopic exploration, if it had been selected, the closure of bile duct incision would accepted by using absorbable suture 4-0 or 5-0, without placing bile duct drainage.It was routinely to place the drainage tube in the oriffice of the lesser omentum. Results 41 out of 42 patients had obtained successful duct clearance, the dilatation of the stenosis to reach the expected expansion and without bile leakage. One patient had bile leakage about 30-150 ml daily persisted for 4 days through cured conservatively. Conclusion Eventually it was safe and effective for some patients who had completed successful duct clearance and the dilatation of the stenosis to reach the expected expansion with the balloon dilatation catheter. They were adopted to the primary closure of duct incision using absorbable suture and did not need to place bile duct drainage.
