Purpose: This study was designed to compare function of patients who had undergone reconstruction following proctocolectomy for ulcerative colitis using the J or W configuration ileoanal pouch.
Methods: Of 126 patients who underwent restorative proctocolectomy between January 1981 and March 1993, 101 had surgery for ulcerative colitis. Eighty-seven of these patients were available for review by personal or postal interview. All operative procedures were performed by one surgeon. The group comprised 35 W-pouches and 52 J-pouches.
Results: More patients with a J-pouch had a stool frequency of greater than 8 per 24 hours (P = 0.044), and they were also more likely to use a perineal pad (P = 0.019). No difference in the rates of nocturnal stool frequency, fecal incontinence, or use of constipating agents between the two pouch designs was found. Significantly more patients with a J-pouch have had episodes of pouchitis (P = 0.001). Of the total patient group 91.9 percent felt that restorative proctocolectomy had improved their quality of life.
Conclusion: Minor differences in the function of the W configuration ileoanal pouch and the J configuration ileoanal pouch are demonstrated in this study.
