Acute Peritonitis due to Uncommon Bacteria

Introduction: Acute appendicitis is the most comment urgency in pediatric population. Some cases has peritonitis with complicated appendicitis; the aim of this study is to report our experience with severe peritonitis caused by strange bacteria

Materials and Methods: We retrospectively analyzed cases treated for peritonitis related to acute appendicitis, between December 2010 and December 2016 aged between 0 and 14 years; all medical charts were reviewed and analyzed.

Results: Among 138 patients with peritonitis 8 cases were studied; during hospital stay we were informed by the pathology service about the bacteria extracted into the appendix and into the peritoneal fluid. One case was diagnosed as having Giardia Lamlia, 4 cases were peritonitis due to enterobius vermicularis, one case was Yersinia enterocolitica and two cases were non typhoidal salmonella. 4 patients developed intraabdominal abscess after surgery that were treated with surgical drainage in two cases and conservatively in the other.

Conclusions: Even if acute appendicitis with peritonitis is not a rare association, there are some cases that require different treatment; rare pathogens could be the cause of these peritonitis and it is better to have a complete fluid analysis are histological evaluation in order to have the best treatment options.
