Abstract
Purpose
To investigate the incidence, complications, and risk factors of the migration of internal pancreaticojejunostomy (PJ) stents into the bile ducts in patients undergoing pancreatoduodenectomy.
Methods
Postoperative computed tomography (CT) and clinical data of 802 patients with CT-detectable internal PJ stents were reviewed to assess the occurrence of stent migration into the bile ducts and stent-induced complications with their clinical significance. Risk factors for stent migration and stent-induced complications were determined.
Results
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. Clinically significant complications were identified in only eight patients. 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.
Conclusions
The incidence of internal PJ stent migration into the bile ducts was 16.8 %. Migrated stents frequently caused complications, although they were mostly subclinical. Stent-induced complications were associated with stent diameter and location, stent remigration to the intestine, and stent retention time in the bile ducts.
