Use of intraabdominal VAC (Vacuum Assisted Closure) lowers mortality and morbidity in patients with open abdomen.

OBJECTIVE Authors compare two groups of patients with open abdomen. The objective is to compare and evaluate two treatment modalities, namely Kern laparostomy and vacuum-assisted closure in terms of mortality, closure of abdominal wound, and fistula management, all these stratified by BMI and CRP. BACKGROUND Open abdomen can be considered a "patient salvage technique", used in patients with abdominal sepsis, as well as in patients with abdominal compartment syndrome, and in damage control surgery. Various management techniques are known, of which Kern laparostomy is most widely used. Newer techniques using negative pressure have emerged, still waiting for their wider acceptance and use. The authors present their study, in which they compare Kern laparostomy and intraabdominal VAC in patients with open abdomen. MATERIAL AND METHODS Study consists of 44 patients treated at the authors´ clinics, while group KERN consisted of patients managed by Kern laparostomy, and group VAC was managed by intraabdominal VAC. The groups were compared in terms of mortality, abdominal closure, appearance of enteroatmospheric fistulas, primary closure of fistulas, and possibility of diversion of enteral contents. All outputs were stratified by CRP (C-reactive protein) and BMI (Body Mass Index). RESULTS In VAC group, a significant decrease in mortality was seen, as well as significantly higher closure of abdominal wall, and significantly higher possibility of diversion of enteral content from fistulas. No statistically significant findings were observed in stratification with CRP and BMI. CONCLUSION Intraabdominal VAC offers patients lower morbidity and mortality and should be defined as a treatment of choice in patients with open abdomen (Tab. 4, Fig. 3, Ref. 15).
