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
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.
Prospective observational cohort study.
Exclusion Criteria:
Patients who present with obstruction due to colon cancer with a need for urgent intervention who are treated with acute resection.
Patients who present with obstruction due to colon cancer with a need for urgent intervention who are treated with bridge to surgery i.e. either stent or stoma and resection later on.
Procedure: Bridge to Surgery (stent or stoma)
The study is an observational study and patients will not be randomized. Resection is defined as upfront surgical resection, Bridge to Surgery as a two stage procedure.
