Background: The postoperative development of benign colorectal anastomotic stricture remains a frequent and unsolved problem. Methods: From 1996 until 2002, we analyzed 94 consecutive patients with postoperative colorectal anastomotic stenosis who were treated endoscopically. Results: Sixty-eight patients were initially resected for malignant disease, and 26 patients for benign conditions. Most frequently, hydrostatic balloon dilatation was performed; in selected cases, it was combined with a laser or argon plasma coagulation (APC) incision, or a laser incision only. Dilatation was successful in 59% of patients resected for cancer and 88% resected for a benign condition. Complications developed in 17 patients (benign restenosis, perforation, abscess); they were significantly more frequent after initial cancer resection than after resection for a benign condition (p < 0.05). Conclusion: High success and low complication rates make endoscopic dilatation the treatment of choice to avoid high-risk reoperations in patients with benign anastomotic stricture. The presence of stapler anastomosis, postoperative leakage, and/or radiotherapy does not significantly impede successful endoscopic dilatation.
