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.

Our results indicate that in patients with infective endocarditis the strongest predictor of mortality is MRSA infection, followed by staphylococcal infection especially in association with older age or with large vegetations. Older patients with large vegetations are also in significant risk of mortality. In these groups of patients surgery should be considered early.

Many patients do not have restoration of bowel continuity after undergoing Hartmann's procedure. Hartmann's reversal is associated with a significant postoperative morbidity. Surgeons and patients should be aware of the possibility that the colostomy might become permanent.
