[Posterior proctomucosectomy and ileal pull-through reconstruction: a new restorative procedure after total proctocolectomy].

Abstract

We reported a new method of restorative proctocolectomy using posterior approach and pull-through reconstruction. This method obviated transanal manipulation, a major factor causing damage to the internal sphincter, thus preventing fecal incontinence due to sphincter dysfunction. Also, temporary ileostomy was not necessary because the spout of an S-pouch was pulled down below the anal verge and its distal free end acted as a diverting stoma while the more proximal, healing zone (future anastomotic line) was kept from fecal contamination. This method was applied to a 32-year-old woman with familial polyposis coli and a 50-year-old woman with ulcerative colitis. Their bowel movements steadily decreased to three times and five times a day, respectively. There was no fecal leakage or perianal excoriation. The advantages as well as disadvantages of this method compared with the conventional techniques were discussed.
