Gastric emptying time(GET) is influenced by several factors, such as neura), hormonal and composi- tion and physiochemical properties of food. The patients with delayed GET have some upper gastrointestinal symptoms such as recurrent nausea, vomiting, postprandia! Bloating, anorexia, and iveight loss. And also, almost of acute hepatitis and a part of chronic ]iver disease patients have similar symptoms of the patients with delayed GET. Therefore We performed GET measurement in liver disease patients to identify the relationship between nonspecific upper gastrointestinal symp- toms and gastric emptying function. The resu]ts are as followings; 1) Total ]iver disease patients are 28 in number, composed of acute hepatitis 3, chronic hepatitis 18, liver cirrhosis 7. 2) The GET(T1/2) of liver disease patients was delayed significantly than that of the normal volunteers. (Mean+SE;120.8+6.6 vs 89.4+5.9 mins.) 3) The GET of the symptomatic patients (N = 20 ) ivas 128.3+6.8 mins (Mean+SE), and that of the asymptomatic patients (N =8) was 101.8+13.2 mins. The symptomatic patients have delayed GET in 10 patients and asymptomatic patients have delayed GET in 3. 4) The GET of the patients who have elevated serum transaminase level higher than twice of normal is delayed significantly than that of the patients who have serum transaminase level lower than twice of normal. (Mean+SE; 143.4+2.6 vs 110.0+7.4 mins.)
