BACKGROUND: The application of stents in benign colorectal strictures is considered controversial. The aim of the present study was to assess effectiveness and complications associated with colorectal stent placement in benign colorectal disease. PATIENTS AND METHODS: Fourteen patients with benign colorectal strictures who had undergone previous surgery (colorectal anastomotic stenosis, 13; neosphincter scar stenosis, one) were treated with covered self-expanding metal stent or plastic stent. Placement of the stent was performed with combined endoscopy and contrast enhanced fluoroscopy. RESULTS: Self-expanding stents were successful implanted in all 14 patients without acute procedure-related complications. All patients experienced immediate decompression after stent placement with expansion and patency of the stent. Relief of bowel obstruction for at least 12 months was achieved in seven of 14 patients (50%). Anastomotic fistula healed in four of six patients (67%). Despite the initial success of stenting, re-operations had to be performed in two of seven patients because of late recurrence of the stricture after a mean follow-up of 37 months. CONCLUSIONS: Temporary insertion of self-expanding stents is a safe procedure that may be effective in selected cases of benign colorectal stricture. However, repeat surgery will be necessary in a considerable number of patients due to primary or secondary failure of stenting.
