Die Proktokolektomie bei Colitis ulcerosa

Background

The coloproctomucosectomy (CPM) is the procedure of the choice for the surgical treatment of ulcerative colitis (UC). In cases with pronounced immunosuppression (IS), a 3-step (3S) procedure [i.e., subtotal colectomy and ileal pouch-anal anastomosis (IPAA) and finally ileostomy reconstruction] is often selected. Fewer perioperative complications can be expected compared to the 2-step (2S) procedure; however, an additional in-hospital stay and surgical intervention are necessary. The aim of the present study was to compare both approaches using the clinical outcome of our patients undergoing IPAA to determine efficacy of these two concepts.

Patients and methods

From 1997–2010, a total of 225 patients were operated using a 2S or 3S IPAA procedure. Clinical outcomes were evaluated based on the number of surgical steps for the ileoanal pouch procedure and IPAA. The survey was performed within the scope of prospective study.

Results

Of the 225 patients with CPM, 66 were excluded due to a diagnosis other than UC (familial adenomatous polyposis, indeterminate colitis, Crohn’s disease) and patients with permanent ILS procedures without the possibility or wish for an IPAA (n?=??54). Included were 71 patients with 2S (w?=?30, m?=?41) and 34 patients with 3S procedures (w?=?21, m?=?13). Compared to the 2S procedure, the 3S procedure was shown to have shorter operation times (246 versus 296 min; p??=?0.05), shorter hospital stays (15.5 versus 24.6 days; p?=?0.05), shorter intensive care unit stays (3.3 versus 7.2 days; p?=?0.05), and fewer major complications (5.9?% versus 22.5?%; p?=?0.035). Patients with 3S procedures had a higher BMI (26.2 versus 23.1 kg/m²; p?=?0.05) and fewer required IS (10?% vs. 62?%; p?Conclusion The decision for a 3S procedure in UC and pronounced IS is advisable and justified. Using a 3S procedure, immunosuppression and its influence on perioperative morbidity are thus reduced. The IPAA can be performed with shorter operation times, shorter hospital stays and fewer major complications.
