The aim of the study was to highlight the incidence of anastomotic stenoses in mechanical colorectal anastomosis associated with colorectal cancer, as well as the risk factors and treatment options. We performed a retrospective evaluation of 203 patients who underwent mechanical colorectal anastomosis associated with colorectal cancer. Several factors related to the patients were analysed as the tumour and the treatment applied. A telephone survey was used, and symptomatic patients were

Stenosis was found in 7 (3.44%) patients. It was defined as the narrowing of the lumen that cannot be pass through with a 12 mm endoscope. Gender, tumour and anastomosis relation to the anal verge, anaemia and perioperative radiation therapy had no statistically significant importance. We have found a statistically significant correlation (P[0.05) for age under 60 years, obesity, tumour perforation and protective ileostomy. Patients were treated by rectal digital or pneumatic dilation and radial incisions. The results were favorable, only one case needed surgical intervention and recreating the anastomoses. Colorectal anastomotic stenosis is a late postoperative complication which influences the patients life quality. By being aware of the prognostic factors of this complication, we would be able to take preventive measures. Our results suggest that age under 60 years, obesity, tumour complication by perforation and protective ileostomy could be statistically significant factors for anastomotic stenoses. Surgical treatment must be reserved for refractory cases, and reanastomosis could be affected by greater risks than in the initial surgery.
