[Surgical treatment of ulcerative rectocolitis: technical aspects of total restorative proctocolitis with S pouch].

Restorative proctocolectomy with an ileal-pouch-anal anastomosis seems to be the treatment of choice for ulcerative colitis. The aim of this study was to discuss a number of technical and functional aspects of the procedure that still appear to be controversial such as the shape of the pouch, the mucosectomy and the type of anastomosis. The authors report on their experience with the surgical treatment of ulcerative colitis with an "S" pouch. The technique reported, however, differs from the original method proposed by Parks and Nicholls in 1978 and the reasons for this surgical choice are discussed. A six-year experience (1993-1999) regarding 35 patients undergoing this approach is reported. No perioperative deaths were observed. The early and long-term complication rates were 8.5% and 11.4%, respectively. The average number of daily evacuations was 4. Mucosectomy affords complete resolution of the disease, while the particular shape of the pouch guarantees good functional results.
