Benign colorectal anastomotic strictures: treatment under fluoroscopic guidance by double balloon dilation / 介入放射学杂志

ABSTRACT

Objective To evaluate the therapeutic efficacy and complications of fluoroscopically guided double balloon dilation in the treatment of benign colorectal anastomotic strictures. Methods Under fluoroscopic guidance, 17 patients with benign colorectal anastomotic strictures underwent transanal double balloon dilation, including 13 patients underwent resection for malignant disease, and 4 for benign conditions. 16 out of 17 patients had difficulty or frequent defecation due to partial obstruction. The remaining one patient had the stricture detected by endoscopy and barium enema after total proctocolectomy and a temporary ileostomy for ulcerative colitis. Therapeutic efficacy and complications were evaluated in the follow-up visits. Results Seventeen patients received double balloon dilation in a single session. The diameter of double balloon catheter was arranged from 30 to 40 mm. Technical success achieved in all 17 patients with complete release (n = 12, 71%) or incomplete one (n = 5, 29%) and 100% improvement of symptoms was achieved in all patients, together with no major complications such as perforation or severe hemorrhage. During the mean follow-up of 23 months (range, 1 - 62 months), one patient (6%) developed a recurrent stricture and needed a second balloon dilation six months after the initial balloon dilation. Conclusions Fluoroscopically guided double balloon dilation is an effective and safe method for treating benign colorectal anastomotic strictures. (J Intervent Radiol, 2006, 15 543-546)
