Aim  The aim of the study was to analyse the incidence of benign colorectal anastomotic stenoses in consecutive patients operated on in a single institution and to assess risk factors for their development. Their impact on quality of life was also evaluated. Method  Patient characteristics, indications for surgery, surgical technique and postoperative complications were prospectively recorded. Stenosis was evaluated by rectoscopy at regular intervals, and patients were treated only if symptomatic. After at least 6 months following surgery, patients were asked to respond to the Short Form 36-item quality-of-life questionnaire during a telephone interview. Results  Of the original 211 patients considered, 195 underwent a follow-up rectoscopy and were included in the study. Benign stenosis were found in 26 (13%), and 19 (73%) symptomatic patients were treated successfully (15 with endoscopic dilatation and four with radial diathermic surgical incisions). Risk factors for anastomotic stenosis according to univariate analysis were female sex, diverticulitis, mechanical anastomosis, and anastomosis located between 8 and 12 cm from the anal verge. The significant risk factors identified by multivariate analysis were diverticulitis (OR 5, P = 0.002) and mechanical anastomosis (OR 9, P = 0.04). The self-perceived quality of life of patients with stenosis was significantly worse compared with controls. Conclusion  Since diverticulitis and mechanical anastomosis are risk factors for anastomotic stenosis, surgeons should take this into account when they are considering what type of anastomotic technique to utilize.

Abstract

Aim  The aim of the study was to analyse the incidence of benign colorectal anastomotic stenoses in consecutive patients operated on in a single institution and to assess risk factors for their development. Their impact on quality of life was also evaluated. Method  Patient characteristics, indications for surgery, surgical technique and postoperative complications were prospectively recorded. Stenosis was evaluated by rectoscopy at regular intervals, and patients were treated only if symptomatic. After at least 6 months following surgery, patients were asked to respond to the Short Form 36-item quality-of-life questionnaire during a telephone interview. Results  Of the original 211 patients considered, 195 underwent a follow-up rectoscopy and were included in the study. Benign stenosis were found in 26 (13%), and 19 (73%) symptomatic patients were treated successfully (15 with endoscopic dilatation and four with radial diathermic surgical incisions). Risk factors for anastomotic stenosis according to univariate analysis were female sex, diverticulitis, mechanical anastomosis, and anastomosis located between 8 and 12 cm from the anal verge. The significant risk factors identified by multivariate analysis were diverticulitis (OR 5, P = 0.002) and mechanical anastomosis (OR 9, P = 0.04). The self-perceived quality of life of patients with stenosis was significantly worse compared with controls. Conclusion  Since diverticulitis and mechanical anastomosis are risk factors for anastomotic stenosis, surgeons should take this into account when they are considering what type of anastomotic technique to utilize.
