Reversal of Hartmann's procedure: still a complicated operation.

Hartmann's procedure, colonic resection with an end colostomy and rectal closure, is used in a variety of surgical emergencies. It is a common surgical procedure that is often practiced in patients with colonic obstruction and colonic perforation, resolving the acute clinical situation in the majority of cases. Reversal of Hartmann's procedure with restoration of bowel continuity occurs in a significantly low percentage of patients. There are several reasons contributing to the fact that many patients remain with a permanent colostomy following Hartmann's procedure. These include factors related to the patients' clinical status but also to the significant difficulty and morbidity related to the surgical reversal of Hartmann's procedure. The aim of this study was to review the factors related to the fairly low percentage of patients undergoing Hartmann's reversal as well as surgical techniques that could help surgeons restore intestinal continuity following Hartmann's procedure and deal with the postoperative outcomes.
