A survey was made in 13 Italian centers with a questionnaire concerning the (a) indications, (b) postoperative complications, (c) functional results and (d) diagnostic imaging modalities related to the making of an ileal or colonic (neo) rectum. Ulcerative colitis (100%), familial polyposis (61.5%) and Crohn's disease (15.3%) were the most common indications for an ileal pouch; rectal cancer (7.96%), chronic inflammatory diseases (15.3%), diverticulosis, rectal prolapse, redundant colon and imperforate anus (7.6% each) were the most common indications for a colonic pouch. Postoperative complications included pelvic abscess (14%), sinus tract/dehiscence (10%) and bowel obstruction (9%). When compared with the S and W variants, the J-shaped ileoanal pouch proved superior because urgency and fecal retention rates were lower (18.4% vs. 44.4% and 23% vs. 28.6%, p < 0.01 and p < 0.05, respectively), despite slightly more frequent staining episodes (15.8% vs. 11.1%; p < 0.05). As for colonic ampullae, fecal retention and provoked evacuation were more frequent in the J pouch and after gracileplasty; urgency and incontinence in the straight colo-anal anastomosis (33.3% vs. 22.2% and 41.6% vs. 33.3%, respectively). The functional outcome was assessed by anal endosonography (available in 4/13 centers), defecography and anorectal manometry. Abnormal findings included: (a) reduced capacity, barium leakage, anal gaping, sphincter damage (urgency and incontinence); (b) barium retention, pouch dilatation, split evacuation, knobs and strictures (fecal retention).
