Discussion Internal stenting of the pancreaticojejunostomy (PJ) has been widely used to reduce the pancreatic fistula rate, although its efficacy is still debatable. Internal PJ stents are generally assumed to pass spontaneously into the small intestine and eventually pass uneventfully through the rectum. Stent migration into the bile ducts occurred in 135 patients (16.8 %); 40 of these (29.6 %) showed stent-induced complications including bile duct stricture, stone, and liver abscess. Neither the stent length nor diameter was associated with stent migration. A small stent diameter, peripheral location of the stent, absence of stent remigration from the bile ducts to the intestine, and longer stent retention time in the bile ducts were risk factors of stent-induced complications.
