A Case of a Mesenteric Abscess Caused by Yersinia Infection

Abstract

A 68-year-old man presented with appetite loss that had persisted for 1 week. A contrast-enhanced computed tomography scan showed a mesenteric abscess of 5.5 cm in diameter in the right lower abdomen. Diagnosis of Yersinia infection was suspected, and ceftriaxone sodium was subsequently administered. However, the abscess did not shrink ; therefore, we performed a resection of the abscess with ileum on the 6th hospital day. The pus culture revealed Yersinia enterocolitica. The patient was discharged on the 9th postoperative day. In case of mesenteric abscess formation due to Yersinia, surgical treatment may be able to reduce the length of hospital stay.
