The colon does not reach! A technical note with tricks to avoid colorectal anastomoses under tension.

Abstract

We describe two options for colorectal anastomosis suitable in cases when the colon would reach the pelvis under tension. Deloyers procedure and the retro-ileal colorectal anastomosis are presented, focusing on practical tips and tricks to perform them. Insights on patients who underwent the procedures are provided to demonstrate the advantages and feasibility of the techniques. Each step of both techniques is detailed. Ten patients underwent Deloyers procedure and nine underwent retro-ileal anastomosis at our unit. A minimally invasive approach was attempted in 13 patients, of whom five required conversion to open surgery due to the technical complexity of the abdominal procedure. Colorectal anastomosis was successfully performed in all patients. There were no major intra-operative complications, although five patients had postoperative complications requiring further treatment. Both techniques are effective in patients at risk of receiving a colorectal anastomosis under tension, and a minimally invasive approach can be used. However, owing to the complexity of surgery in this group of patients, the perioperative morbidity is not negligible. Careful postoperative management is advisable, and patients should be informed of the risks. In expert hands, the outcomes are acceptable, avoiding an ileorectal anastomosis and its constraints.
