Postoperative pneumoperitoneum on computed tomography: is the operation to blame?

Background: Postoperative radiographs demonstrating pneumoperitoneum are a vexing problem for surgeons. This dilemma stems from uncertainty regarding the length of time for resolution of gas introduced operatively via either an open or a laparoscopic approach. We attempted to quantify the duration of pneumoperitoneum after both laparoscopic and open surgery in an animal model.

Cellular changes of the colon after mechanical bowel preparation.

Background: The purpose of this study was to evaluate the effect of mechanical bowel preparation (MBP) on the intracellular environment, specifically evaluating butyrate transport, within the colon of the Sprague-Dawley rat.

Methods: Sixty-eight Sprague-Dawley rats were randomized to either an MBP group (n = 34) or a control group (n = 34). Twenty-four hours after the completion of the MBP, both groups were euthanized, and the colons were harvested.
