OBJECTIVE To investigate the clinical application of a new temporary abdominal wound closure,vacuum system for temporary management of the open abdomen. METHODS Vacuum pack system consisted of polyethylene sheet,surgical towel,silicone drain, adhesive plastic drape. Clinical data of the patients undergoing exploratory celiotomy were recorded,and the indications for such temporary abdominal closure and its complications were reviewed. RESULTS Thirteen trauma patients underwent such vacuum abdominal closure for 15 times, including 5 times (33.3%) for increased intra- abdominal pressure so that tension-free fascial closure was unable to achieve, 4 times (26.7%) for reexploration, 2 times (13.3%) for damage control, and 4 times (26.7%) for combined factors. Finally, seven patients (53.8%) received direct closure and 5 patients (38.5%) received skin grafting after granulation because the defect could not be closed directly. One patient (7.7%) died before abdominal closure was attempted. None of the patients developed enterocutaneous fistula and evisceration. Three patients (23.1%) developed intra-abdominal abscess. CONCLUSIONS The vacuum pack is a better temporary abdominal wound closure device, and primary closure can be achieved in most of the patients. The technique is simple and easily mastered with a low complication rate.
