Restorative proctocolectomy is now the operation of choice for the definitive management of ulcerative colitis and familial adenomatous polyposis coli. The aim of this review is to evaluate clinical and functional results of the first fifty patients treated with restorative proctocolectomy over a period of seven years. A total of 50 patients (28 males, 22 females) underwent restorative proctocolectomy over a period of seven years in our district general hospital. A retrospective analysis of hospital notes was undertaken and supplemented with a patient questionnaire. Forty-three patients had ulcerative colitis and seven had familial adenomatous polyposis coli. Two pouch designs were used, a four limbed "pear pouch" (94%) and a two limb "J" pouch (6%). The majority (98%) of patients had a stapled ileal pouch-anal anastomosis and a similar number had a defunctioning ileostomy. There was no mortality. Early complications (within 30 days of operation) occurred in 18(36%) patients. Late complications were seen in 22 (44%) patients. The median number of daily bowel movements was four (range 1-10). Pouchitis was seen in ten patients (20%). Restorative proctocolectomy is a safe procedure for patients with ulcerative colitis and familial adenomatous polyposis coli. Although total morbidity is appreciable, functional results are generally good and patient satisfaction is high.
