Abstract
Objective: We aimed to investigate the difference in complications between native papilla and bilioenteric anastomosis cases in bile duct treatment by double-balloon enteroscopy-assisted ERCP (DB-ERCP) for a postoperative reconstructed intestinal tract. Methods: In the 4 years from January 2012 to December 2015, Roux-en-Y reconstruction cases and bilioenteric anastomosis cases were investigated retrospectively, which attempted to treat biliary tract with double balloon small intestine endoscope. Results: No complications were observed in 15 patients who did not arrive at the target site or failed to undergo bile duct treatment. Cases successfully treated with bile duct were divided into two groups for assessing complications: one group comprised 34 cases of native papilla and the other group comprised 21 cases of bilioenteric anastomosis. The complication rates were 20.6%, including 11.8% of pancreatitis and 8.8% of cholangitis in the native papilla group, and 19.0%, including 4.8% of pancreatitis and 14.3% of cholangitis in the bilioenteric anastomosis group. Conclusion: There was no significant difference in the incidence of complications between the two groups. However, it should be noted that in the bilioenteric anastomosis group, pancreatitis can occur without transpapillary treatment and cholangitis can occur without stenosis of the bile duct.
