[Auxiliary drainage of the intraperitoneal course of transhepatic tubes in benign common bile duct stenosis]

The authors used Penrose drains around intraperitoneal portion of Silastic tubes to prevent subphrenic collections in transhepatic intubation. In 31 cases of benign stenosis of the biliary tree, this peritoneal drainage was employed in 18 and no collections were observed. In the other group, 3 patients developed subphrenic abscess. Even with a result not statistically significant (P less than 0.05), the authors consider the procedure useful in transhepatic intubation.
