Are our endoscopy patients at risk for pyogenic liver abscess?

Schemmer P, Cerwenka H
This is an editorial comment on a recent publication reporting an increased rate of pyogenic liver abscesses (PLAs) after upper gastrointestinal panendoscopy. Its aim is to critically highlight the findings, limitations and potential clinical implications of this study. Issues of the mucosal barrier, the microbial flora, administration of antibiotics and underlying diseases are discussed. The probability of PLAs after endoscopies is not exactly known and the length of the "incubation period" remains unclear, but a possible causality should already suffice to make us think how to avoid them. Especially in patients with risk factors such as diabetes mellitus, end-stage renal disease, liver cirrhosis, biliary tract infection, and malignancies, the potential risk for PLAs should be considered. Unnecessary insufflation during endoscopy (causing mucosal stretching and microscopic tears) as well as mucosal damage (by direct abrasion with the scope) should be avoided in order to limit the invasiveness of the procedure as much as possible. And, in everyday routine, it should be kept in mind that in patients after endoscopy, especially in those with a breach of the mucosal barrier and significant comorbidities, PLAs can potentially develop and require timely administration of antibiotics as well as further diagnostic and therapeutic steps.
