Preserved function of the remnant stomach in pylorus-preserving gastrectomy by gastric emptying scintigraphy - Evaluation between the length of antral cuff and remnant gastric emptying

本研究通过胃排空显像评价保幽门胃切除术（PPG）患者残胃的保存功能，并探讨该检查方法是否为评估残胃功能的有用工具。方法：应用胃排空显像评价45例早期胃癌行PPG的残胃功能，并根据胃排空曲线分为快速排空型、中间排空型和延迟排空型。然后，研究胃排空类型与餐后症状、食物摄入状况、体重变化和内镜检查结果之间的关系。结果：73%的PPG患者属于中间排空型，其余为延迟排空型。延迟排空型患者出现上胃饱足、恶心、呕吐等主诉的频率较高。中间排空型患者比延迟排空型患者消耗更多的食物，体重增加更多。结论：用胃排空显像评价PPG患者的胃排空功能。该方法不仅可用于评价残胃运动功能，而且可用于预测术后状态。

This study evaluated the preserved function of the remnant stomach by gastric emptying scintigraphy in patients who underwent pylorus-preserving gastrectomy (PPG), and investigated whether this examination method is a useful tool for evaluation. Methods : The residual stomach function was evaluated by gastric emptying scintigraphy in 45 patients with early gastric cancer who had undergone PPG, and was classified into rapid, intermediate, and delayed emptying types according to gastric emptying curves. Then, the relationships were examined between the gastric emptying types and postprandial symptoms, food intake status, body weight changes, and endoscopic findings. Results : Seventy-three percent of the PPG patients were classified as belonging to the intermediate emptying type, and the remainder to the delayed emptying type. The frequencies of complaints such as epigastric fullness, nausea, and vomiting were high in the delayed emptying-type patients. The intermediate emptying-type patients consumed larger amounts of food, and gained more weight than the delayed emptying-type patients.Conclusion : Gastric emptying function was evaluated by gastric emptying scintigraphy in PPG patients. This method is useful not only for evaluating the motor function of the remnant stomach, but also for predicting postoperative status.
