Background/aims: Vacuum-assisted closure (VAC) leads to a high fascial closure rate in open abdomen within the first week of treatment. However, little data exist on the role of long-term VAC treatment in patients with peritonitis, where fascial closure cannot be accomplished within the first days.
Methods: We reviewed the medical records of 49 patients with open abdomen for more than 7 days due to secondary peritonitis, who underwent a VAC-treatment. Nonparametric analysis was performed using chi(2) test or Fisher's exact test.
Results: Fascial closure could be accomplished in only 11 patients (22%), whereas complications occurred in 43 patients (88%). Re-explorations after starting VAC were associated with the occurrence of enterocutaneous fistula (p < 0.001) and were also of prognostic value regarding the rate of fascial closure (p = 0.033).
Conclusions: If fascial closure cannot be accomplished within the first days, patients show a dramatically lower fascial closure and an increased complication rate with VAC. Further studies are needed to evaluate whether this subgroup really benefits from VAC.
