STUDY OF POSTGASTRECTOMY FATTY LIVER

Fatty liver was often found concomitantly by the ultrasound during the follow up study of the gastric cancer operation. By ultrasound, development of postgastrectomy fatty liver was seen in 29 out of 176 patients (16.5%) with several gastrectomies. The number of the patients with postgastrectomy fatty liver was 12 out of 104 patients (11.5%) with distal partial gastrectomy with B-I reconstruction, while that was 17 of 72 patients (23.6%) with total gastrectomy with several reconstructions. The incidence of postoperative fatty liver change was significantly higher in the patients under 59 years old compared to the olders.
Seventy-five g oral glucose test induced oxyhyperglycemia and hyperinsulinemia in patients with gastrectomy, especially with total gastrectomy. Integrated plasma insulin and triglyceride responses during first one hour in postgastrectomy patients were significantly higher than preoperative values. Moreover, plasma insulin and blood sugar in response to oral glucose test were significantly higher in patients with postgastrectomy fatty liver, compared to those in patients without fatty liver.
These results suggested that the postgastrecomy fatty liver was resulted from the abnormality of the glucose metabolism.
