Simplified laparoscopic approach to "second-look" laparotomy: a review.

Acute mesenteric vascular accidents are being diagnosed more commonly as a consequence of an aging population and often result in emergency bowel resection for ischemia. Because predicting postoperative intestinal viability remains difficult, second-look laparotomy has been advocated to improve outcomes. Recently, laparoscopy has emerged as an alternative to laparotomy for the diagnosis and treatment of ongoing postoperative ischemia. A review of the literature since 1994 reveals that, to date, 19 procedures have been reported to prevent 13 (68%) unnecessary laparotomies. We describe our laparoscopic second- look technique and review the literature. Second-look laparoscopy has been shown repeatedly to be a safe alternative to laparotomy. It is simple and reduces negative second-look laparotomy in critically ill patients.
