The aim of this prospective observational study is to evaluate primary resection for malignant obstruction of the colon compared to only decompression as first intervention regarding postoperative outcomes. We hypothesize that patients with malignant obstruction benefit from avoidance of emergency cancer resection, by a two-stage procedure, with decompression by a stoma or stent as first intervention, leading to decreased short-term morbidity and mortality and improved long-term oncological outcome.
P patients with acute obstructive colon cancer I resection or bridge to surgery with stent or stoma C emergency procedure O morbidity and mortality within 30 days, 90 day mortality and 3 & 5 years overall survival
