title: Changes in outcome and management of perforated diverticulitis over a 10 year period.
abstract: BACKGROUND
  Aggressive non-operative intervention and evolving surgical strategies have altered the treatment of perforated diverticulitis in the acute setting. These strategies have predominantly been implemented over the last decade. The aim of this study was to assess the impact of this on patient outcome during their index admission and subsequently.
  
  
  METHODS
  Consecutive patients admitted with acute diverticulitis between 1999 and 2010 were identified. Patient demographics, treatment strategies and outcomes were collected and analysed. Patients who had an episode of perforated diverticulitis during their index admission were followed.
  
  
  RESULTS
  739 patients were admitted with acute diverticulitis. Of these, 115 (15.7%) had perforated diverticulitis. 53 (47.8%) underwent an intervention. There was a reduction in the mean age of patients admitted with acute diverticulitis of 8.9% over the study period (p = 0.002). There was a significant increase in the use of CT scanning pre-operatively (p < 0.001). 'Non-resectional' interventions have emerged in the form of laparoscopic lavage (n = 5) and percutaneous abscess drainage (n = 14). There was associated improved length of stay (p < 0.001).
  
  
  CONCLUSIONS
  Outcomes for patients with perforated diverticulitis have improved, contributed to in part by an increased use of non-resectional management strategies.
