Endoscopic stenting for selected cases of biliary fistula after hepatic hydatid surgery.
BACKGROUND
Biliary fistula develops in 4%-28% of patients after hepatic hydatid disease (HHD) surgery. Although endoscopic retrograde cholangiopancreatography (ERCP) and endoscopic sphincterotomy (ES) are helpful in the treatment of this complication, persistent fistulas may occur. We therefore conducted a study to evaluate the efficacy of endoscopic biliary stenting in the treatment of biliary fistulas after HHD.


METHODS
In this study, 84 patients who underwent ERCP for postoperative biliary fistula due to HHD were evaluated. Group I included 70 patients treated with only ES, and group II included 14 patients who underwent biliary stenting as their initial treatment. Demographic data, complications, the results of treatment and the reasons for the failure were compared between two groups.


RESULTS
Ninety-five ERCPs were performed. In 63 patients, biliary fistulas were successfully treated with only ERCP and ES. However, 7 patients underwent repeat ERCP and stent placement because of persistent fistula. Biliary stenting was initially performed in 14 patients. The average time for closure of the fistula was 14 +/- 10 days and 7 +/- 3 days in group I (7 patients with repeat ERCP were excluded) and group II, respectively (p = 0.007). There was no statistically significant difference in the complication rates between the groups.


CONCLUSIONS
Although ES is effective in the treatment of biliary fistula after HHD surgery, endoscopic biliary stenting may be considered as the initial procedure in patients with biliary stricture, incomplete clearance of hydatid material in the bile duct, and persisting biliary fistulas after treatment with ERCP and ES.
