Surgical management of primary crohn's disease. descriptive study about 226 patients.

BACKGROUND: The surgery is required in more than 80% of patients with Crohn's disease (CD). Studies before confirm the specific genetic variation of CD in the Tunisian population compared with the others ethnic groups. AIM: This article aims to study the epidemiological, anatomical and therapeutic principles of surgical forms of CD in a cohort of Tunisian patients. METHODS: We report a retrospective study from January 1998 to September 2010 that studied 226 patients originated only from Tunisia (in North Africa), operated on for MC. We had been interested in epidemiological, anatomical, clinical, therapeutic, topographic progression of the disease, the procedure and the postoperative follow-up. RESULTS: The median age was 33 years. The average time between the onset of the disease and the surgical procedure was 31 months. The diagnosis of CD was established preoperatively in 213 patients (94%). The diagnosis was made intraoperatively because of an acute complication in 5 cases (2.2%) and postoperatively in 8 cases (3.5%). The most common location was the ileocecal junction in 184 cases (81.4%). Achieving the most common was the mixed form (stricture and fistula) in 123 cases (54.4%). Operative mortality was 0.04% (n = 1). Specific morbidity was 8.4% (n = 19). In long term, a surgical recurrence was noted in 17 patients (7.5%). In multivariate analysis the independent risk factors for surgical recurrence were: smooking (p = 0.012, ORs = 3.57) and post-operative medical treatment (p = 0.05, ORs = 2.6). CONCLUSIONS: Achieving stenosing and fistulizing the ileocecal junction is the most frequent surgical form in Crohn's disease. Our series is unique for a lower rate of the postoperative recurrence (7.5%).
