Endoscopic ret-rograde cholangiopancreatography(ERCP) was performed under fluoroscopic control using a total length of 120 cm oblique-viewing duodenoscope with a 3.7-mm diameter working channel. For this procedure, we used a triplelumen retrieval balloon catheter in which a 0.035-inch guidewire could be inserted into the "open-channel" guidewire lumen while the balloon could be simultaneously injected and inflated through the other 2 lumens.RESULTS: For the patients with Billroth Ⅱ gastroenterostomy and Braun anastomosis, successful access to the papilla was gained in 17 patients(85%) and there was therapeutic success in 16 patients(80%). One patient had afferent loop perforation, but postoperative bleeding did not occur. For Billroth Ⅱ gastroenterostomy, there was failure in accessing the papilla in 15 patients(13.8%). ERCP was unsuccessful because of tumor infiltration(6 patients), a long afferent loop(9 patients), and cannulation failure(4 patients). The papilla was successfully accessed in 94 patients(86.2%), and there was therapeutic success in 90 patients(82.6%). Afferent loop perforation did not occur in any of these patients. One patient had hemorrhage 2 h after ERCP, which was successfully managed with conservative treatment.CONCLUSION: Retrieval-balloon-assisted enterography along an optimal route may improve the ERCP success rate after Billroth Ⅱ gastroenterostomy and Braun anastomosis.展开更多
