In patients undergoing emergency laparotomy, every attempt should be made to localize the bleeding intraoperatively, because segmental colectomy is the preferred procedure. If the bleeding site is not localized, a subtotal colectomy is performed with an inherent morbidity rate of around 37% and a mortality rate of about 11-33%. In unstable patients, a two-stage procedure is preferred: temporary end ileostomy and delayed ileoproctostomy. In a small group of hemodynamically stable patients with minimal medical morbidity, this procedure can be performed as a single-stage procedure with ileoproctostomy. In addition, postoperative diarrhea can be a significant problem in elderly patients who undergo subtotal colectomy and ileoproctostomy.
