To help in decision making the authors wish to suggest surgeons to consider 3 further key points approaching OLCC: patient stratification according to the ACPGBI

rules; clinical environment; surgeon skill. The target as usual is to offer the best option for the patient; starting from this point of view also historical surgical option could still play a valid role. The staged procedure, with preference to the two stages, should be reserved when multimodality therapy is expected or in case of “”dramatic”" scenarios. PRA with manual decompression is a safe option and appears to be associated with best outcomes. HP might still have a role in patients at high risk for anastomotic dehiscence. TC is an appealing

option in case of synchronous polyps or CP673451 cancer and/or impending or actual perforation of the right colon. SEMS represent a valuable option both for palliation and as a bridge to elective surgery. Obviously high clinical and technical expertise is mandatory to safely and successfully treat colonic obstruction by stents: due to this consideration routine use in practice is still limited. However we strongly support a judicious application of the procedure and encourage increased

use of stents after adequate training in referral hospitals with a goal of further testing this modality.
