Many patients who complain of postprandial bloating discomfort and episodic nausea and vomiting exhibit abnormally slow gastric emptying of a standard meal during scintigraphic study. Nevertheless, on clinical grounds, the group of slow emptiers would appear to be comprised of two types of patients: (1) those with primary motor dysfunction (pump failure) and (2) those who have normal muscle performance but abnormally intense inhibition of gastric emptying by nutrients in small intestine (too much feedback). Our studies suggest that these two groups may be distinguished by varying the nutrient content in the test meal during multiple studies of gastric emptying.
许多主诉餐后腹胀不适、发作性恶心和呕吐的患者，在闪烁扫描研究中表现出标准餐的胃排空异常缓慢。然而，基于临床理由，胃排空缓慢的患者群体似乎可分为两类：（1）原发性运动功能障碍（泵衰竭）患者；（2）肌肉功能正常但小肠内营养物质对胃排空的抑制异常强烈（反馈过多）的患者。我们的研究表明，在多次胃排空研究中改变测试餐的营养成分，可能有助于区分这两组患者。
