Changes in gallbladder motility in gastrectomized patients

OBJECTIVES: Gastric resection may predispose gallstone formation. However, the mechanism has not been clearly understood. To evaluate the relationship between gastric resection and gallstone formation, we compared gallbladder(GB) motility in gastrectomized patients and control subjects. METHODS: We compared the GB volume and ejection fraction of the 46 gastrectomized patients with 37 healthy controls using real time ultrasonography. RESULTS: GB volume increased significantly in the gastrectomized group in fasting (30.2 13.9 ml). The GB volume after a fatty meal was greater in the gastrectomized group (12.6 6.4 ml) than in the control group (4.3 3.3 ml) (p +ADw- 0.01). A significant reduction of ejection fraction was found in gastrectomized patients (56.9 13.0+ACU-) in comparison with the control group (75.5 16.1+ACU-) (p +ADw- 0.01). The GB ejection fraction had a poor correlation to the postoperative period (r +AD0- 0.232). CONCLUSION: A gastrectomy appears to be a risk factor of GB dysmotility, which may play a major role in gallstone formation in gastrectomized patients.

Nutritional Status in Alcohol- and Virus-Related Liver Cirrhosis / 대한간학회지

AIMS: The purpose of this study was to explore the differences of general characteristics and nutritional factors such as anthropometry and dietary intake between alcohol-related cirrhosis and virus-related liver cirrhosis and to assess the nutritional status of both of these groups. METHODS: In this study, the nutritional status of 67 patients with liver cirrhosis (25 with alcohol-related and 42 with virus-related) was evaluated by using clinical assessment, anthropometric measurements, dietary intakes, and biochemical indices. RESULTS: Although anthropometric measurements were not significantly different between alcoholic cirrhosis and viral cirrhosis, anthropometry of patients with viral cirrhosis had a higher tendency than that of alcoholic cirrhotic patients. Alcohol intake factors such as amount, duration, and frequency in alcoholic cirrhotic patients were higher than those in patients with viral cirrhosis. Energy excluding alcohol and vitamin C were significantly different between patients with alcoholic and viral cirrhosis. All subjects had lower intake of energy excluding alcohol, protein, vitamin A, thiamin, riboflavin, niacin, calcium, and iron as than recommended by the Recommended Dietary Allowances (RDA) for Koreans. Of special note was the fact that the intakes of energy excluding alcohol, vitamin A, riboflavin, and calcium were less than 75% of RDA for Koreans. Although the glucose and triglyceride levels were significantly different between alcoholic and viral cirrhotic patients, there were within normal range in both groups. There was an interaction effect in triceps skinfold thickness of the subjects according to both etiology and severity of liver disease. CONCLUSION: These data suggests that nutritional disorders are common in patients with both alcohol-and virus-related cirrhosis. It is necessary to educate patients with cirrhosis about the importance of a balanced dietary intake as well as its pattern, and quality of diet.
