AIM: To assess the use of topical negative pressure (TNP) in the management of severe peritonitis.METHODS: This is a four-year prospective analysis from January 2005 to December 2008 of 20 patients requiring TNP following laparotomy for severe peritonitis. RESULTS: There were 11 males with an average age of (59.3 ± 3.95) years. Nine had a perforated viscus, five had anastomotic leaks, three had iatrogenic bowel injury, and a further three had severe pelvic inflammatory disease. TNP and the VAC Abdominal Dressing System were initially used. These were changed every two to three days. Abdominal closure was achieved in 15/20 patients within 4.53 ± 1.64 d. One patient required relaparotomy due to residual sepsis. Two patients with severe faecal peritonitis due to perforated diverticular disease received primary anastomosis at second look laparotomy, as sepsis and their general condition improved. In the remaining 5/20 cases, the abdomen was left open due to bowel oedema and or abdominal wall oedema. Dressing was switched to TNP and VAC GranuFoam. Three of the five patients returned a few months later for abdominal wall reconstruction and restoration of intestinal continuity. Two patients developed intestinal fi stulae. All 20 patients survived.CONCLUSION: The use of TNP is safe. Further studies are needed to assess its value in managing these difficult cases.
