Background: Observational studies have suggested lap peritoneal lavage may be better than resection for perfed diverticulitis.
Sweden/Norway study, n=199 patients presenting with diverticulitis with free air on CT.
Severe post-op complications were similar in both groups (31% lavage v 26% resection), mortality at 90 d (14% v 12%), LOS and QOL. Rates of reoperation higher in lavage group, 4 of which required reoperation for missed sigmoid cancers.
Conclusion: Resection for perfed diverticulitis is superior.
