Endoscopic management with inside stent for proximal benign biliary stricture after laparoscopic cholecystectomy.

Endoscopic placement of a plastic stent is the standard drainage for a symptomatic benign biliary stricture. Although a removable fully covered self-expandable metal stent has been applied for distal benign biliary stricture, placement of a plastic stent remains the standard treatment for proximal benign biliary stricture. Placement of a plastic stent above the papilla (inside stent) is an alternative to the conventional method because of its preventive effect against the dysfunction of the stent in patients with proximal benign biliary stricture.
