Abstract/OtherAbstract:
PURPOSE: To investigate the technical feasibility and clinical efficacy of a retrievable covered stent for treating postoperative bile leaks.
MATERIALS AND METHODS: This is a prospective study conducted from August 2007 to July 2009. Eleven patients with postoperative bile leak involving bilioenteric anastomosis (n = 8), cystic duct stump (n = 2), and the right intrahepatic bile duct (n = 1) were treated using a percutaneous retrievable covered stent. In five patients (45.5%), there were anastomotic (n = 2) or nonanastomotic (n = 3) strictures in addition to bile leaks. All of the retrievable covered stents were removed percutaneously by retrieval hook wires.
RESULTS: Placement and removal of the retrievable covered stents were technically successful in all study patients. The stents were removed 14-64 days (mean, 31 days) after placement. Stent migration occurred in one (9.1%) of 11 patients. After stent removal, clinical success was achieved in all the study patients. Biliary drainage catheters were withdrawn at a mean of 41 days (range, 20-80 days) after percutaneous transhepatic biliary drainage. During the mean follow-up period of 366 days (range, 215-730 days), recurrence was not noted in any patient.
CONCLUSIONS: Placement and removal of a retrievable covered stent is technically feasible and appears to be a clinically effective method for treating postoperative bile leak as well as combined stricture.
