long and short type double balloon enteroscopy assisted therapeutic ercp for intact papilla in patients with a roux en y anastomosis
2011Co-Authors: Takao Itoi, Kentaro Ishii, Atsushi Sofuni, Fumihide Itokawa, Takayoshi Tsuchiya, Toshio Kurihara, Shujiro Tsuji, Nobuhito Ikeuchi, Katsumasa Fukuzawa, Fuminori MoriyasuAbstract:Background There have been a few previous reports on attempted double-balloon endoscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anastomosis and an intact papilla. This study was designed to evaluate the usefulness of DBE-assisted ERCP in patients with Roux-en-Y anastomosis and an intact papilla of Vater.

2011Co-Authors: Takao Itoi, Kentaro Ishii, Atsushi Sofuni, Fumihide Itokawa, Takayoshi Tsuchiya, Toshio Kurihara, Shujiro Tsuji, Nobuhito Ikeuchi, Katsumasa Fukuzawa, Fuminori MoriyasuAbstract:There have been a few previous reports on attempted double-balloon endoscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anastomosis and an intact papilla. This study was designed to evaluate the usefulness of DBE-assisted ERCP in patients with Roux-en-Y anastomosis and an intact papilla of Vater. Thirteen DBE procedures were performed in nine patients who had undergone Roux-en-Y reconstruction combined with eight total gastrectomies and one partial gastrectomy. Both short-type and long-type DBE were used. Long-type DBE was replaced with a conventional forward-viewing upper endoscope after reaching the papilla. Technical success rate, measurement of procedure times, and adverse events were evaluated in the retrospective study. In all cases, the scopes could reach the papilla. The mean time required to reach the papilla was 48 (range, 13–90) min. There was a statistically significant difference with the short and long scope (29.0 ± 19.2 min vs. 64.8 ± 24.7 min, respectively; P = 0.044). The success rate of bile duct cannulation, resulting in achieving therapeutic ERCP on the first session was 66.7% (6/9). The mean procedural time in the successful cases was 128 (range, 47–183) min. Finally, therapeutic ERCP was achieved in all nine cases. There was one adverse event in which retroperitoneal perforation during lithotripsy, but that was successfully treated by conservative therapy alone. DBE-assisted ERCP seems to be a promising option to perform therapeutic ERCP for intact papilla in patients with a Roux-en-Y anastomosis.

large balloon dilatation following endoscopic sphincterotomy using a balloon enteroscope for the bile duct stone extractions in patients with roux en y anastomosis
2011Co-Authors: Takao Itoi, Kentaro Ishii, Atsushi Sofuni, Fumihide Itokawa, Takayoshi Tsuchiya, Toshio Kurihara, Shujiro Tsuji, Nobuhito Ikeuchi, Junko Umeda, Rena TanakaAbstract:Abstract Background Extraction of bile duct stones in patients who have undergone Roux-en-Y anastomosis can be challenging. Recently, large balloon dilation following endoscopic sphincterotomy has been shown to be useful for the removal of bile duct stones. Aim We retrospectively evaluated the feasibility and safety of endoscopic sphincterotomy large balloon dilation for the removal of bile duct stones in patients with Roux-en-Y anastomosis. Methods Large balloon papillary dilation following EST for the removal of bile duct stones was performed on the intact papilla in 15 patients with Roux-en-Y anastomosis at our institution. When we could not use the long-type accessories, a conventional forward-viewing upper endoscope passed through the over tube of the single-balloon or double-balloon enteroscope for the use of short-type accessories. Following endoscopic sphincterotomy, a large balloon catheter was positioned across the main duodenal papilla. The size of large balloon used ranged from 15 mm to 20 mm. Results Complete clearance of bile duct stones was achieved in all cases in the initial session without any adverse events. A mechanical lithotriptor for crushing stones was used in one patient (6.7%). Conclusion Large balloon papillary dilation following EST appears to be an effective and safe treatment for difficult-to-remove bile duct stones in patients with Roux-en-Y anastomosis .
