Clinical and functional results after restorative proctocolectomy

Of 84 patients who underwent restorative proctocolectomy with an ileoanal reservoir in 21 Italian departments of surgery, 51 had ulcerative colitis, 32 familial polyposis and 1 intractable constipation. Follow-up information is available for all 58 patients who had their ileostomy closed, the length of follow-up ranging between 2 and 78 months. There were no operative deaths. A failure rate (i.e. excision of the pouch) of 3 per cent was observed. Sepsis was the most common postoperative complication, and was most often related to ileoanal anastomosis dehiscence (15 per cent), followed by small-bowel obstruction requiring laparotomy (10 per cent). Clinical 'pouchitis' occurred in 14 per cent of patients after ileostomy closure. The average frequency of defaecation was four motions per 24 h; evacuation was spontaneous in all patients and only 5 per cent complained of troublesome faecal soiling while 34 per cent had occasional incontinence to flatus and mucus. Patients with a short or absent rectal cuff had a lower rate of incontinence (30 versus 48 per cent, difference not statistically significant) without any increase in the frequency of genito-urinary disorders. None of the two most used reservoirs, the J (n = 40) and S pouch (n = 17) showed significant superiority in terms of bowel frequency and continence. Incontinence was more likely in patients whose ileostomy closure had been delayed for more than one year.
