Colonic stenting or surgery in left-sided colonic obstruction for disseminated incurable colorectal cancer: a multicenter randomised trial

Study hypothesis: 1. Patients with incurable disseminated left-sided colonic cancer are better palliated by colonic stenting than surgery, measured by hospital free survival in "good health" (World Health Organization [WHO] score 0 or 1)
2. Colonic stenting is cost effective in patients with incurable disseminated left-sided colonic cancer
Primary outcome(s): 1. Total hospital free survival in good health (corrected for days with a WHO performance status greater than 1)
2. Integral costs (product of volume consumed care and prices of means (personnel, overhead, material and investments)
