目的：探讨ＢｉｌｒｏｔｈⅡ（ＢⅡ）术后固体餐的残胃排空和小肠转运动能。方法：应用ＰＨＹ９９ｍＴｃ标记的固体餐，对正常健康者（Ａ组）、胃窦癌病人（Ｂ组）和ＢⅡ病人（Ｃ组），分别进行胃排空和小肠转运功能的研究。结果：Ｃ组餐后１０ｍｉｎ胃排空率比Ａ、Ｂ组显著增加（Ｐ＜０．０１）；胃半排空时间明显减少（Ｐ＜０．０１）。而初排后胃的排空率Ｃ组［（２８３±５４）％／ｈ］及Ｂ组［（２６±５２）％／ｈ］均比Ａ组［（３８７±４５）％／ｈ］低。小肠转运时间Ｃ组比Ａ、Ｂ组显著延长（Ｐ＜０．０１）。结论：ＢⅡ病人和胃窦癌病人胃初排空后存在胃排空延迟现象。同时，前者初排空显著加快，且小肠转运时间明显延长 Objective: To investigate the residual gastric emptying and intestinal transit kinetic energy of solid meal after BilrothⅡ (BⅡ). Methods: The gastric emptying and small intestine transit were studied by using PHY99mTc labeled solid meal, respectively, in normal healthy subjects (group A), gastric antrum cancer patients (group B) and BⅡ patients (group C). Results: The gastric emptying rate in group C ten minutes after operation was significantly higher than that in groups A and B (P <0.01). The gastric emptying time was significantly decreased (P <0.01). However, the rate of emptying in the rear row was significantly higher in group C than in group A [(283 ± 54)% / h] and group B [(26 ± 52)% / h] [(387 ± 4  5)% / h] low. Intestinal transit time in group C was significantly longer than that in groups A and B (P <0.01). Conclusion: There is a delayed gastric emptying in patients with B Ⅱ and gastric antrum after initial emptying. At the same time, the former significantly faster initial emptying, and intestinal transit time was significantly longer
