Aims: After distal partial gastrectomy with Billroth I reconstruction, gastritis of the remnat stomach was previously considered to be caused by bile reflux. However, since in 1982,
Helicobacter pylori (HP) was discovered and it was found that this organism caused for many types of stomach diseases. The affect of HP must also be examined in the remnant stomach. In a current study, we examined the existence of HP and explored bile reflux as a pathogenesis of gastritis of the remnant stomach after distal partial gastrectomy. Patients and Methods: The subjects were 56 patients who underwent gastrectomy. The existence of HP was investigated before and after gastrectomy. At postoperative gastroscopy, we examined histological findings of remnant gastritis and total bile acid (TBA) concentration in the gastric juice. Then we assesed the effect of HP and TBA on gastritis regarding the time after gastrectomy. Result: HP was positive in 75% of the patients before the operation and in 37.5% after the operation. The HP positive ratio was significantly lower in patients more than 5 years after gastrectomy than in those within 5years. Inflammatory cell infiltration of the remnant gastric mucosa was more prominent in HP positive patients than in HP negative patients. In HP positive remnant stomachs, the TBA concentration of the gastric juice was lower than in HP negative remnant stomachs. Conclusion: Within 5 years after distal partial gastrectomy, gastritis of the remnant stomach was mainly caused by HP.

Four hundred and twenty-one patients with hepatocellular carcinoma who firstly underwent transcatheter arterial chemoembolization were divided into three groups as “younger”(32-69yr-old, n=340), “elderly”(70-79yr-old, n=74) and “super-elderly”(80-89yr-old, n=7). Between “younger” and “elderly”, clinical stage of underlying liver disease, stage of hepatocellular carcinoma and tumor necrosis rate at first treatment did not differ significantly. In these two groups, the first year survival rates were 83.2, 79.7%, the third year survival rates were 47.2, 36.5% and the fifth year survival rates were 22.9, 14.5% respectively. Cumulative survival rate of the “elderly” was similar to the “younger”. Factors significantly affecting the survival period included advanced clinical stage of underlying liver disease and hepatocellular carcinoma, poor tumor necrosis at the first treatment and high serum α-fetoprotein level in the “younger” and high α-fetoprotein, advanced stage of hepatocellular carcinoma and presence of other than liver disease in “elderly”. Transarterial chemoembolization is useful for the treatment of hepatocellular carcinoma in the “elderly” with the attention for their underlying diseases.

In this study, we elucidate a relationship between final outcome and changes in hepatic and splenic volume in patients with acute severe hepatitis. The subjects were 40 patients: 10 with sever acute hepatitis (prothrombin time<40%) and 30 with fulminant hepatic failure (acute type in 12 and subacute type in 18). Liver and spleen volume were measured by CT initially on hospitalization and subsequently 1 to 40 days after hospitalization, and the scans were analyzed retrospectively. Liver volume decreased in 15 of 26 survivors, and all 14 non-surviuors. Among 15 surviuors and 14 non-survivors whose liver volume decreased, spleen volume increased in none of the survivors, whereas it increased in 11 of the 14 non-survivors. In survivors, there was a close parallelism between changing rates of the liver volume and that of the spleen volume (r=0.82, p<0.0001). These observations suggest that the decrease of liver volume accompanied by that of spleen volume implies a good prognosis, while the decrease without such accompaniment implies a bad prognosis.
