小儿全胃食管床移植术后胃排空的变化

Research of gastric evacuation after transplantation of whole stomach

目的 :观察小儿全胃食管床移植后胃排空的变化。方法 :对 14名全胃食管床移植术 (均未附加幽门成行术 )后患儿和 6名健康儿童进行99m锝标记固体食物的胃排空研究。全胃食管床移植术患儿又分为术后近期组 (8例 ,术后 3～ 4周 )和术后远期组 (6例 ,术后 1～ 4a)。结果 :术后近期组胃半排空时间明显延迟 (70 34± 10 30 )min ,与正常对照组 (4 2 2 6± 4 7)min比较 ,差异有显著性 (P <0 0 1)。术后远期组胃半排空时间 (4 2 2 1± 7 41)min与正常对照组比较差异无显著性 (P >0 0 5 )。结论 :全胃移植治疗小儿食管瘢痕性狭窄 ,胃排空延迟现象并不持续存在 。

Aim: To research the gastric evacuation after transplantation of whole stomach Methods: 14 children after transplantation of whole stomach without pyloroplasty and six normal children were given solid food labeled with 99m TC to research gastric evacuation The former was divided into short term group (8 cases, 3～4 weeks after operation ) and long term group (6 cases, 1～4 years after operation) Results: Compared with the control(GET 50 =(42 26±4 7)min),the gastric evacuation of the short term group was remarkable delayed(GET 50 =(70 34±10 30)min), the difference was significant( P <0 01), however, that of the long term group (GET 50 =(42 21±7 41)min)had no significant difference ( P >0 05) Conclusion: In the transplantation of whole stomach in the treatment of children with cicatricial stenosis of esophagus, the delay of gastric evacuation isn't continuous, and polyroplasty is unnecessary
