A Rare Case of an Exploratory Laparotomy to Treat a Liver Abscess Secondary to Foreign Body Ingestion.

A 49-year-old female presented to the hospital with complaints of generalized weakness, subjective fevers, and chills. In the emergency department (ED), she was found to be hypotensive and tachycardic and met the sepsis criteria. A CT scan of the abdomen and pelvis (CT A/P) with contrast revealed a liver abscess and a foreign body (FB) that was suspected to be the cause of the liver abscess. Of note, the patient had undergone a recent dental procedure due to an infected root canal, which had involved a dental screw. The patient was uncertain whether the dental screw had been removed, but she felt as though it was no longer there. At this time, the clinical suspicion was high for FB secondary to this dental procedure. The patient underwent interventional radiology (IR)-guided liver abscess drainage and magnetic resonance cholangiopancreatography (MRCP) for the evaluation of the FB. An esophagogastroduodenoscopy (EGD) was performed, but no evidence of the FB was found. This warranted an exploratory laparotomy (EL) to ensure the successful removal of the FB. Upon gross visualization by surgery, the FB was revealed to be a bone that the patient did not recall ingesting. However, surgical pathology evaluation revealed that the FB was actually a plastic stick. This rare case highlights the clinical approach to FB ingestion when complicated by liver abscess, as well as successful treatment with EL as opposed to laparoscopy which is the procedure of choice.
