Answer: Gastrohepatic Fistula Following TACE for HCC

Transarterial chemoembolization is a commonly used treatment modality for unresectable HCC. It involves the use of transarterial catheters to deliver local high doses of chemotherapy to the tumor. Often, particulate embolic agents are also administered with the chemotherapy to eliminate the arterial vascular supply of the lesion. Transarterial chemoembolization therapy can be quite effective in treating HCC, resulting in tumor response in 16% to 61% of patients.1Data on whether TACE offers a survival benefit to patients with HCC remains somewhat controversial.2Two randomized trials3,4have suggested that there is no survival benefit, while 2 other randomized studies have reported an improvement in survival following TACE.5,6Although TACE can usually be performed safely, it can be associated with complications. The most common complication is acute liver failure secondary to hepatic necrosis. Other complications include acute renal failure, encephalopathy, and gastrointestinal bleeding. More rare ischemic complications have also been reported, including hepatic and splenic abscess, gastric and duodenal ulcerations, and biliary stricturing. Often, these complications are attributed to leaking of chemoembolic agents into collateral vessels that supply other organs outside of the tumor bed with blood.7To our knowledge, this is the first reporting of a hepatogastric fistula following TACE therapy.

This patient was discussed at the multidisciplinary tumor board with interventional radiologists, hepatobiliary surgeons, and oncologists to determine the best course of action to address the fistula. The technical details of the embolization were also reviewed. There was no concern that the chemoembolization agents had inadvertently entered the gastric vessels at the time of the initial TACE. Evaluation of the fistula defect on computed tomography (Figure 2) demonstrated that the liver was well drained into the stomach without any extravasation of enteric contents. Since the patient was clinically well with a contained fistula, it was felt that no further intervention was warranted. After discussion with the patient, surgical intervention was not recommended given the patient’s extensive medical comorbidities and his baseline poor prognosis related to his underlying cirrhosis and advanced HCC. As such, the patient was treated with palliative supportive care.
