An interesting article from Archives on the optimal treatment of children who present with perforated appendicitis. Previous dogma dictated an initial non-operative approach---- dick around with IV antibiotics, CT guided drains, etc--- and then bring the child back in 6-8 weeks for an "interval appendectomy". This article demonstrates that getting the kid into the OR ASAP leads to better outcomes and a faster return to normal activities.
I've advocated for this approach before. Explore the kid laparoscopically, evacuate any abscess collections, leave a drain in certain cases, and take the damn appendix out. I would even extrapolate from the pediatric population and apply such management to all patients with complex appendicitis.
