Laparoscopic surgery has spread worldwide and become a standard procedure among many abdominal surgical fields. The incidence of postoperative adhesion, which is a typical postoperative complication, is considered low compared with that after laparotomy. However, once complications develop, such as adhesion-induced intestinal obstruction and chronic abdominal pain, the low-invasiveness of laparoscopic surgery can decrease markedly. While we have previously used a sheet-type anti-adhesion barrier, it requires a specific technique in many cases when it is applied in the abdominal cavity. In this study, we used a spray-type anti-adhesion barrier, which is considered simple to apply, as an adhesion-preventing absorbable barrier following laparoscopic surgery.
