Comparison of the functional results of restorative proctocolectomy for ulcerative colitis between the J and W configuration ileal pouches with sutured ileoanal anastomosis

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.Read in part as the Bacon Oration at The meeting of the American Society of Colon and Rectal Surgeons, Chicago, Illinois, May 2 to 7, 1993.
