Pyogenic liver abscess secondary to gastric perforation of an ingested toothpick: A case report.

ABSTRACT

BACKGROUND: Liver abscess due to foreign body-induced gastrointestinal tract perforation is a rare event that could be misdiagnosed due to low suspicion. Less than 100 cases have been reported to date. CASE SUMMARY: We report a case of a 53-year old female patient with pyogenic liver abscess secondary to ingestion of a toothpick with penetration through the lesser curvature of the stomach. The patient presented with persistent epigastric pain. Abdominal computed tomography demonstrated the presence of a linear radiopaque object associated with abscess formation in the left liver lobe. Inflammatory changes in the lesser curvature of the stomach indicated gastric wall penetration by the object. As the abscess was refractory to antibiotic treatment, laparoscopic liver resection was performed to remove the foreign body and adjacent liver parenchyma. Following surgery, symptoms fully resolved without any sequelae. CONCLUSION: This rare case demonstrates the importance of considering foreign body penetration as a cause of pyogenic liver abscess, particularly in abscesses of unknown origin that are resistant to antibiotic therapy. Clinical suspicion, early diagnosis, and prompt removal of the foreign body could lead to improved outcomes in these patients.
