Colon and rectal surgery for cancer without mechanical bowel preparation: one-center randomized prospective trial.

Background: Mechanical bowel preparation is routinely done before colon and rectal surgery, aimed at reducing the risk of postoperative infectious complications. The aim of the study was to assess whether elective colon and rectal surgery can be safely performed without preoperative mechanical bowel preparation.

Methods: Patients undergoing elective colon and rectal resections with primary anastomosis were prospectively randomized into two groups.

Complicated small-bowel diverticulosis: a case report and review of the literature.

Here we report a case of a 60 years old woman who came to the Emergency Department of San Martino Hospital suffering from abdominal pain for about a week with high fever in the last 24 hours. The final histological examination led to the diagnosis of ileal diverticulosis associated with perforation and peritonitis with a fibrotic reaction involving the last ileal loop, the caecum and the appendix.
