Primary Objective:~• first assessment of the safety of applying A-Part® Gel as adhesion prophylaxis after major abdominal surgery by specific observation of two major complications of abdominal surgery (wound healing impairment, and/or postoperative peritonitis) in comparison to a control group.~Secondary Objectives:~To further evaluate the safety of A-Part® Gel by comparing the incidences of adverse events between the treatment groups (with special attention to anastomosis leakage)~To explore the efficacy of A-Part® Gel in reducing post-surgical adhesions after median laparotomy
The safety of applying A-Part® Gel intra-peritoneally under the incision in order to prevent post-surgical adhesions after median laparotomy.
