Abstract
The rate of SSI is high in cases of acute diffuse peritonitis due to lower gastrointestinal perforation. Since April 2011, we have been performing NPWT in order to achieve delayed primary closure instead of primary closure, as was previously applied in our hospital. Twenty-three patients who had undergone surgery in our hospital between April 2009 and March 2012 were divided into groups of NPWT (group A) and primary closure (group B). There were no cases of superficial SSI in group A (0%) and seven cases in group B (43.8%). The average length of stay in hospital of the patients in group A was 28.0 days, while it was 46.2 days in group B. Group B had a propensity toward a longer stay. A comparison between group A and group B who had undergone reopening of wound due to SSI revealed a significant difference (p=0.04) in terms of the days until wound healing. The average number of days for group A was 24, compared with 56 for group B. Management of wound with NPWT was more effective than that of SSI after primary closure. Thus, we can report that this treatment was highly effective.
