Recurrent appendicitis after conservative management of perityphlitic abscess: report of two cases.

We report on two cases of recurrent appendicitis after conservative management consisting of antibiotics and percutaneous drainage of perityphlitic abscess. The first patient presented 13 years after acute appendicitis with a perityphlitic abscess that was treated operatively. This patient refused to undergo interval appendectomy after the initial event. The second patient with appendicitis and perityphlitic abscess was equally managed conservatively initially but presented with reperforated appendicitis and diffuse peritonitis 1 week before scheduled interval appendectomy and also had to undergo surgery. Based on our experience with these two cases, we conclude that interval appendectomy after the recommended period of 6-12 weeks might not be appropriate and may better be managed by performing it in the case of a recurrence.
