Clinical results of colectomy for severe constipation.
Subtotal colectomy has been performed in 40 patients with severe constipation. Only one patient was male. Five patients (13 per cent) had a history of a serious psychiatric disorder. Twenty-six patients (65 per cent) could not expel a 100-ml air-filled balloon and 19 patients (48 per cent) had electromyographic evidence of abnormal puborectalis contraction during attempted defaecation before operation. Median preoperative passage of 50 radio-opaque markers over 5 days was 16 per cent. Sixteen patients had had a previous anorectal myectomy to exclude Hirschsprung's disease. Initial resections were subtotal colectomy and ileorectal anastomosis (n = 34), caecorectal (n = 5) or ileosigmoid (n = 1) anastomosis. Secondary operations included restorative proctocolectomy and ileal pouch-anal anastomosis (n = 6) and six patients eventually had an ileostomy. Median bowel frequency per week significantly increased after operation (0.3 (range 0-1) preoperatively to 21 (range 2-70) postoperatively, P less than 0.005), the percentage of patients with abdominal pain fell after operation from 93 to 39 per cent but symptoms of abdominal distension remained the same (86 per cent preoperatively and 82 per cent postoperatively).
