This is a prospective randomized clinical study. The study will comprise the randomized decision to either A) primarily close the fascia after laparotomy for intra-abdominal infection (CLOSED); or B) leave the fascia open after laparotomy and apply a temporary abdominal closure (TAC) device (OPEN) with a vacuum drain. Although debatable, both procedures (CLOSED or OPEN abdomen) are acceptable based on current suggested standard of care. Thus, high quality data to direct clinical decision making in this highly lethal condition is urgently required.
