Objective: With the use of abdominal vacuum therapy, we have developed a damage control concept for patients with perforated diverticulitis and generalized peritonitis. The primary aim of this concept was to enhance recovery and allow bowel reconstruction in a second-look operation.
Methods: A total of 51 patients (28 female, 55%) with a median (range) age of 69 (28-87) years, with perforated diverticulitis Hinchey III (n = 40, 78%) or Hinchey IV (n = 11, 22%) and a median (range) Mannheim peritonitis index of 26 (12-39), admitted between October 2006 and September 2011, were prospectively enrolled in the study. At initial operation, limited resection of the diseased segment, lavage, and application of abdominal vacuum-assisted closure dressing was performed. After patient resuscitation, a second look was performed in an elective setting.
Results: Hospital mortality rate was 9.8%; 35 (76%) of patients were discharged with reconstructed colon, and 93% of patients live without a stoma at follow-up. Risk factors for mortality were American Society of Anesthesiologist score (p = 0.01), organ failure at initial presentation (p = 0.03), cardiac comorbidity (p = 0.05), and a Hartmann procedure at second look (p = 0.00).
Conclusion: With this abdominal vacuum-based damage control concept, an acceptable hospital mortality rate and a high rate of bowel reconstruction at second look were achieved in patients with perforated diverticulitis and generalized peritonitis.
