Percutaneous transhepatic cholangioscopic treatment of patients with benign bilio-enteric anastomotic strictures.
BACKGROUND
Percutaneous transhepatic cholangioscopy is a nonoperative method for accessing bilio-enteric anastomotic strictures that cannot be reached via the transpapillary route. This study evaluated the immediate and long-term results of treatment via percutaneous transhepatic cholangioscopy of patients with benign bilio-enteric anastomotic strictures.


METHODS
A retrospective analysis was conducted of 21 patients who, between October 1994 and March 2001, had undergone percutaneous transhepatic cholangioscopy for bilio-enteric anastomotic strictures. Follow-up ranged from 12 to 79 months (mean 33.3 months).


RESULTS
The initial technical success rate was 100%, and the short-term morbidity and mortality rates were, respectively, 14.3% and 0%. However, strictures recurred in 8 patients (38.1%) at a mean of 17.1 months (range 2-38 months). The success rate exclusive of patients with recurrent strictures was 61.9%, and the overall success rate was 81.0% when the procedures were repeated. The long-term morbidity rate was 38.1%, but most complications resolved with conservative treatment. In 17 patients (81.0%), strictures were complicated by biliary stones, and these were successfully treated via percutaneous transhepatic cholangioscopy (stone removal rate 94.1%, recurrence rate 37.5%).


CONCLUSIONS
Percutaneous transhepatic cholangioscopy-based treatment of patients with benign bilio-enteric anastomotic strictures is safe and effective. This minimally invasive method frequently can be used as a substitute for surgery.
