Evaluation of efficacy of Vascular Closure Staple in primary closure of common bile duct

Abstract

In this study we performed common bile duct repair using non-perforating vascular closure staple (VCS) clips made of titanium that were originally developed for vascular anastomosis, and evaluated the effectiveness and problems associated with their uses. VCS clips were used in 7laparotomy operations and 13 laparoscopic operations in patients with common bile duct stones. In the laparotomy operations, the VCS clips were effective and useful for primary closure of the common bile duct. In laparoscopic choledochotomy, to close common bile duct directly using VCS was possible by using stay sutures and forceps, however bile leakage and stenosis of bile duct were occurred after operation in one emergent case. In other cases, bile duct stenosis and recurrence of stones have not occurred after operation. We suggest that VCS clips may be useful for primary closure of the common bile duct.
