Radical gastrectomy with hepatoarterial catheter implantation for late-stage gastric cancer

Table 1 Classification of hepatic metastases from gastric cancer proposed by the Japanese Gastric Cancer Association

H-0	No liver metastases
H-1	Liver metastases limited to one lobe of the liver
H-2	Isolated diverse metastases in both lobes of the liver
H-3	Multiple distributed metastases in both lobe of the liver

¹Two cases in the radical resection group had biliary leakage. Both recovered and were discharged at 10 and 14 d postoperatively, once leakage stopped;

²Two cases in each group suffered from anastomosis with moderate to severe discomfort. Both complained of acid regurgitation, eructation or bloating; both of which were alleviated after 2-4 wk domperidone and omeprazole.
