Improved Health-Related Quality of Life After Surgical Management of Severe Refractory Constipation-Dominant Irritable Bowel Syndrome

摘要

Irritable bowel syndrome (IBS) is the most common of the functional gastrointestinal disorders (FGIDs). Despite its prevalence and health-care costs, there are few effective therapies for patients with severe symptoms. Our objective was to determine whether surgical management would improve health-related quality of life (HRQOL) in severe refractory constipation-dominant FGIDs. From 2003 to 2005, 6 patients underwent total colectomy with end ileostomy or primary anastomosis. They completed Short Form 36 (SF-36) and IBS-36 questionnaires preoperatively and postoperatively. HRQOL was compared with age- and sex-matched Canadian norms using Welch's unpaired t test. Preoperative SF-36 physical and mental health summary scores were significantly lower than Canadian norms (P < 0.0001), while postoperative scores were not significantly different than Canadian norms (P = 0.50 and P = 0.57, respectively). After surgical management, HRQOL in patients with severe constipation-dominant IBS improved from drastically below that of Canadian norms to a comparable level. This finding questions the convention of avoiding operations in IBS patients and demonstrates that surgical management may be suitable for the appropriately screened patient.
