通常认为溃疡病手术后某些副作用的产生及其严重程度取决于肠道内容物反流入胃的数量,然而正常人群及术后无症状者反流的发生率不明。采用~(99m)Tc HlDA(系经胆汁分泌)静脉给药后以γ射线照相扫描与计数,能对各种临床情况下反流的发生率及程度作定量的比较,且因无需置放胃管,不致干扰胃肠道功能而更符合生理。 The incidence and severity of some of the side effects after ulcer surgery are generally believed to depend on the amount of intestinal contents that flow back into the stomach, however, the incidence of reflux in asymptomatic and normal populations is unknown. With 99mTc HlDA (Department of bile secretion) after intravenous administration of gamma-ray scanning and counting, can be a variety of clinical conditions, the incidence and extent of reflux for quantitative comparison, and because there is no need to place the stomach Tube, will not interfere with gastrointestinal function and more in line with physiology.
