tial effect, 3.0 (2.8) days (range, 1-7 days) for BT-B vs 14.3 (6.7) days (range, 7-20 days) for BT-A. Anhidrotic areas developed earlier in the BT-B side. Patients reported longer-lasting subjective benefit from BT-B than BT-A: 17.3 (7.4) weeks vs 12.9 (8.4) weeks.All patients tolerated intradermally injected BT-A and BT-B well, although some experienced mild pain, especially during BT-B injections. No hematomas developed at the injection site, nor did any participant report systemic adverse effects.

The combination of endoscopic electroincision and hydraulic balloon dilatation leads to a high long-term clinical success with a minimum of complications. Therefore, in our opinion it is a useful method in the treatment of benign colorectal anastomotic strictures.
