Surgical treatment of colostomy complications

One hundred and twenty‐three patients (M:F, 0.9:1; mean age 62 years) underwent 156 operations between 1954 and 1984 for correction of late colostomy complications (stenosis 65 patients, prolapse 16 patients, paracolostomy hernia 42 patients). Sixty‐three per cent of patients eventually had a good result but in some up to 5 operations were necessary. Local excision of scar tissue at the mucocutaneous junction was associated with a 61 per cent (43/71) success rate for relief of colostomy stenosis. Where local fixation failed to prevent recurrent colostomy prolapse (13/20, 65 per cent of local fixation operations), colectomy and ileostomy was the most effective second procedure (2/3,67 per cent success rate). Where local repair of a paracolostomy hernia failed (15/32,47 per cent of local operations), resiting of the stoma to the umbilicus or right side of the abdomen produced better results (3/7, 43 per cent success rate) than resiting to another trephine on the left side of the abdomen (2/14, 14 per cent success rate).
