AIM: To evaluate the success rates of performing therapy utilizing a rotational assisted enteroscopy device in endoscopic retrograde cholangiopancreatography(ERCP) in surgically altered anatomy patients. METHODS: Between June 1, 2009 and November 8, 2012, we performed 42 ERCPs with the use of rotational enteroscopy for patients with altered anatomy(39 with gastric bypass Roux-en-Y, 2 with Billroth Ⅱ gastrectomy, and 1 with hepaticojejunostomy associated with liver transplant). The indications for ERCP were: choledocholithiasis: 13 of 42(30.9%), biliary obstruction suggested on imaging: 20 of 42(47.6%), suspected sphincter of Oddi dysfunction: 4 of 42(9.5%), abnormal liver enzymes: 1 of 42(2.4%), ascending cholangitis: 2 of 42(4.8%), and bile leak: 2 of 42(4.8%). All procedures were completed with the Olympus SIF-Q180 enteroscope and the Endo-Ease Discovery SB overtube produced by Spirus Medical. RESULTS: Successful visualization of the major ampulla was accomplished in 32 of 42 procedures(76.2%). Cannulation of the bile duct was successful in 26 of 32 procedures reaching the major ampulla(81.3%). Successful therapeutic intervention was completed in 24 of 26 procedures in which the bileduct was cannulated(92.3%). The overall intention to treat success rate was 64.3%. In terms of cannulation success, the intention to treat success rate was 61.5%. Ten out of forty two patients(23.8%) required admission to the hospital after procedure for abdominal pain and nausea, and 3 of those 10 patients(7.1%) had a diagnosis of post-ERCP pancreatitis. The average hospital stay was 3 d.CONCLUSION: It is reasonable to consider an attempt at rotational assisted ERCP prior to a surgical intervention to alleviate biliary complications in patients with altered surgical anatomy.
