The role of the distal stomach in gastric emptying was studied. Ten patients with proximal gastric vagotomy (PV) and 10 age-matched patients with Roux-en-Y gastro-jejunostomy (R-Y) were compared with 10 healthy controls. Gastric emptying of solids and liquids was determined by the use of Tc-99m SC scrambled eggs and In-111 DTPA. In PV, gastric emptying of both solids and liquids was delayed; the prolongation with solids was mainly accounted for by an abnormal lag phase. In R-Y patients, no lag phase was observed, and the solid emptying curve pattern was characterized by early rapid emptying followed by very slow emptying. Both the solid and liquid phases were prolonged. The lag phase is affected by proximal vagotomy and is mainly determined by the distal stomach, which appears to be essential for normal emptying.
研究了胃远端在胃排空中的作用。将10例近端胃迷走神经切断术（PV）患者和10例年龄匹配的Roux-en-Y胃空肠吻合术（R-Y）患者与10名健康对照者进行比较。通过使用Tc-99m SC炒鸡蛋和In-111 DTPA来测定固体和液体的胃排空情况。在PV患者中，固体和液体的胃排空均延迟；固体排空延长主要是由异常的延迟期所致。在R-Y患者中，未观察到延迟期，固体排空曲线模式的特点是早期快速排空，随后排空非常缓慢。固体和液体相均延长。延迟期受近端迷走神经切断术影响，并主要由胃远端决定，胃远端似乎对正常排空至关重要。
