Background: Small bowel obstruction secondary to intra-abdominal adhesions is a frequent postoperative complication. Less invasive surgery carries a lower risk of postoperative adhesions, but adhesions may still occur after laparoscopic colorectal surgery. We present here some of our methods of adhesion prophylaxis for laparoscopic colorectal surgery. Methods: The 167 patients who underwent laparoscopic colorectal surgery at our center from 2007 to 2012 were retrospectively reviewed. To prevent postoperative intra-abdominal adhesions, anti-adhesion barriers were placed using the half-overlap method. The rate of postoperative small bowel obstruction was compared among three groups: patients who received no adhesion prophylaxis (Group NP), patients who received single-layered adhesion prophylaxis adjacent to the incision (Group SP), and patients who received three layers of adhesion prophylaxis at different depths (Group MLP). Results: The rate of postoperative ileus was significantly different among the three groups, at 9.7 % (6/62) in Group NP, 5.0 % (1/19) in Group SP, and 0 % (0/86) in Group MLP). Conclusions: This retrospective analysis found that placement of multi-layered anti-adhesion barriers using the half-overlap method provided the most effective prophylaxis. Prospective clinical trials are needed to further evaluate these methods of anti-adhesion prophylaxis.
