Abstract
INTRODUCTION AND IMPORTANCE: Stenosis of the colostomy occurs in 2-15% of patients and, they are the cause of serious discomfort for the patient due to the difficulty in evacuation, as well as the need for new surgical interventions. The purpose of this work demonstrates an outpatient surgical treatment that can be performed in the office. CASE PRESENTATION: Three patients with definitive colostomy who suffered progressive stenosis are presented. Under local anesthesia, one or two triangular segments, with their bases on the colostomy, which included the thickened and hardened skin, are removed to expand the diameter of the stoma. The mucosa of the colon is sutured to healthy skin with Vicryl 3/0 simple stitches. This method has been used in three patients older than 60 years with permanent colostomy who presented with progressive stenosis 6-7 months after surgery. The average follow-up at 14.5 months was satisfactory, without restenosis. DISCUSSION: Stoma stenosis is a complication that occurs in up to 15% of cases and requires reconstruction, most of which are carried out in the operating room. The triangular stenoplasty presented is effective and is performed under local anesthesia in the office. CONCLUSION: Triangular-section stenoplasty of a stenosed permanent colostomy is an effective outpatient treatment.
