Gastric emptying of a standard semifluid test-meal, labeled with 99mTc-DTPA, was studied by functional scintigraphy in 88 subjects (normals, patients with duodenal and gastric ulcer before and after selective proximal vagotomy with and without pyloroplasty). Gastric emptying curves were analysed by the method of principal components. Patients after selective proximal vagotomy with pyloroplasty showed an rapid initial emptying, whereas this was a rare finding in patients after selective proximal vagotomy without pyloroplasty. The method of principal components is well suited for mathematical analysis of gastric emptying; nevertheless the results are difficult to interpret. The method has advantages when looking at larger collectives and allows a separation into groups with different gastric emptying.
采用功能性闪烁扫描术，对88名受试者（正常人、十二指肠溃疡患者、胃十二指肠溃疡患者在选择性近端迷走神经切断术前后，伴或不伴有幽门成形术）进行了研究，观察了用99mTc - DTPA标记的标准半流质试验餐的胃排空情况。采用主成分分析法对胃排空曲线进行分析。行选择性近端迷走神经切断术加幽门成形术的患者表现出快速的初始排空，而在未行幽门成形术的选择性近端迷走神经切断术患者中，这一情况较为少见。主成分分析法非常适合对胃排空进行数学分析；然而，结果难以解释。该方法在研究较大样本时具有优势，并且能够将具有不同胃排空情况的人群区分开来。
