A series of 1,630 patients with gastric cancer was reviewed with special reference to their ages. The overall resectability rate was 84.6%. With increasing age, there was also an increase in: the male-to-female ratio, the frequency of tumors located in the distal third of the stomach, and the degree of differentiation of the carcinoma (p less than 0.01). There was no age-related association to: tumor size, early gastric cancer of 30-40%, macroscopic classification, histological staging, or symptomatology. The 5-year survival rates did not differ significantly among the various age groups. From 1980 to 1984, clinical characteristics were evaluated in 58 patients under 40 years of age and in 39 patients 80 years of age and older. Preexisting medical illnesses and postoperative complications were more frequent in the aged group; however, there were no operative deaths in either group. In conclusion, although there are several distinct properties depending on the age of the patients, very elderly as well as young patients can be successfully treated.

Aberrant gastric venous drainage into the medial segment: demonstration by color Doppler sonography.

BACKGROUND: Aberrant gastric venous drainage (AGVD) into the posterior edge of the medial segment of the liver (segment IV) is the main cause of pseudolesion on computed tomography (CT) during arterial portography. We estimated the prevalence of AGVD into the medial segment of the liver with color and power Doppler ultrasound (US). METHODS: Screening gray-scale and color Doppler and power Doppler US were performed in 100 consecutive patients. AGVD was defined as a venous structure that ascended parallel to the main portal vein and drained independently into segment IV. RESULTS: AGVDs were observed in eight of 100 patients (8%) with color and power Doppler US. Power Doppler US depicted these veins more clearly than did color Doppler US. Gray-scale US did not show any AGVDs. Two of eight patients with AGVDs detected by color Doppler US underwent celiac arteriography and CT during arterial portography (CTAP). In these two patients, celiac arteriography directly demonstrated AGVDs draining into segment IV, which revealed nontumorous perfusion defects (pseudolesions) on CTAP. CONCLUSION: Color and power Doppler US are useful imaging methods for demonstrating AGVDs.
