Benign stricture is a relatively common complication of colorectal anastomosis after low anterior resection. On occasion, the anastomosis may close completely. A variety of endoscopic techniques have been described, but there is a lack of data from controlled prospective trials as to the optimal approach. Through-the-scope balloon dilatation is well known and easy to perform. Some case reports describe different endoscopic approaches, including endoscopic electrocision with a papillotomy knife or hook knife. We report a case of a colorectal anastomosis web occlusion, treated without electrocision. Gastrografin enema and sigmoidoscopy showed complete obstruction at the anastomotic site due to the presence of an anastomotic occlusive web. In order to avoid thermal injuries, we decided to use a suprapapillary biliary puncture catheter. The Artifon catheter was inserted into the center of the circular staple line at the level of the anastomosis, and fluoroscopic identification of the proximal bowel was obtained with dye injection. A 0.025-inch guidewire was then passed through the catheter into the colon and progressive pneumatic dilatation was performed. The successful destruction of the occlusive web facilitated passage of the colonoscope, allowing evaluation of the entire colon and stoma closure after three months of follow-up. The patient tolerated the procedure well, with no complications. This report highlights an alternative non-electrosurgical approach that uses a new device that proved to be safe and useful.
