title: [Endoscopic dilatation of benign colon and rectum stenosis].
abstract: OBJECTIVE
  To determine the usefulness of endoscopic dilatation in dealing with benign stenosis of the anus, rectum and colon. PATIENTS AND METHODS USED: Thirty six (36) patients with stenosis, anus (8), rectum (22) and colon (6) were given endoscopic treatment using hydroneumatic balloons, electro incision (radiated cuts) or a combination of both. Rigid equipment (metal) was used for distal stenosis. Age ranged between 30 and 82 years. Twelve (12) patients were male and 24 female. The diameter of the stenosis was less than 13 mm in 18 of the patients and 11 patients carried colostomy.
  
  
  RESULTS
  All 36 patients were subjected to a total of 113 dilatation sessions. The average number of sessions per patient for patients with anal stenosis was 2.5 and for patients with colorectal stenosis, 3.32. One patient with rectal stenosis required 21 sessions to achieve final objective. The result achieved was good in 31 patients, less than satisfactory in 3 patients and bad in one patient, who presented a stenosis which was over 5 cm long. We lost track of a patient in the follow up stage. Success in closing the colostomy was achieved in 9 patients, while one presented a complication due to the procedure (cervical emphysema) which remitted with medical attention.
  
  
  CONCLUSIONS
  Endoscopic dilatation offers, through its different techniques, a safe and efficient method for the treatment of benign stenosis of the anus, rectum and colon and must be considered as a first class tool for the treatment of this kind of pathologies.
