A variety of scintigraphic techniques has been added to the gastroenterologist's armamentarium for the evaluation of motor dysfunction of the upper gastrointestinal tract and hepatobiliary tree. These methods include: esophageal transit scintigraphy for the measurement and quantitation of aboral movement of liquids through the esophagus, and for the measurement of esophageal clearance; gastroesophageal reflux scintigraphy for the detection and quantitation of gastroesophageal reflux, gastric scintigraphy for the physiological measurement of the simultaneous rates of emptying of liquids and solids from the stomach; hepatobiliary scintigraphy for the detection of acute cholecystitis, biliary tract obstruction, bile leaks; and enterogastric reflux scintigraphy for the detection and quantitation of bile reflux from the small bowel into the stomach. Each of these methods is relatively physiologic in comparison to other modalities in that none requires intubation or other nonphysiologic maneuvers. Each offers the practicing internist, surgeon, and gastrointestinal physiologist, the ability to measure normal and abnormal function in patients. Because of the low radiation burdens involved and high patient acceptance, these methods are suitable for serial studies in the same patient, particularly before and after the application of various therapeutic modalities.
为评估上消化道和肝胆系统的运动功能障碍,胃肠病学家的诊疗手段中增加了多种闪烁扫描技术。这些方法包括:食管通过闪烁扫描,用于测量和定量液体通过食管的向肛运动以及食管清除率;胃食管反流闪烁扫描,用于检测和定量胃食管反流;胃闪烁扫描,用于生理学测量液体和固体从胃中排空的同步速率;肝胆闪烁扫描,用于检测急性胆囊炎、胆道梗阻、胆漏;以及小肠胃反流闪烁扫描,用于检测和定量胆汁从小肠反流至胃。与其他检查方式相比,这些方法中的每一种都相对符合生理情况,因为它们都不需要插管或其他不符合生理的操作。每种方法都能让内科实习医生、外科医生和胃肠生理学家测量患者的正常和异常功能。由于辐射负担低且患者接受度高,这些方法适用于对同一患者进行系列研究,尤其是在应用各种治疗方式之前和之后。
