Malignant hepatogastric fistula with associated secondary liver abscess: a rare complication of an occult gastric adenocarcinoma.

A 73-year-old woman presented with fever and right flank pain. The admission was complicated by sepsis, myocardial ischaemia and an upper gastrointestinal bleed. A gastroscopy eventually demonstrated a large antral adenocarcinoma. Further imaging showed no evidence of metastasis, but demonstrated a large segment 3 hepatic abscess. At laparotomy, a hepatogastric fistula (HGF) was noted and a synchronous subtotal gastrectomy and left lateral liver sectionectomy was performed. Final histology showed complete resection of the gastric cancer (T4bN2) and confirmed the presence of the fistula. The patient was discharged 10 days later. She passed away 6 months later with local recurrence, hepatic and pulmonary metastasis. We include a review summarising the other causes of HGF in the literature.
