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 ,术中不需附加幽门成形术
Objective: To observe the changes of gastric emptying after pediatric whole-stomach esophageal bed transplantation. Methods: Gastric emptying of 99m-Tc-labeled solid food was performed in 14 children with full gastrectomy (all without pyloric surgery) and 6 healthy children. The children with full-stomach esophageal bed transplantation were further divided into the immediate postoperative group (8 cases, 3 to 4 weeks after operation) and the postoperative long term group (6 cases, 1 to 4 days after operation). Results: The gastric emptying time was significantly delayed in the immediate postoperative period (70 34 ± 10 30 min), which was significantly different from that in the normal control group (4262 ± 47 7 min) (P 0 01). Postoperative long-term gastric emptying half-time (4 2 2 1 ± 7 41) min compared with the normal control group no significant difference (P gt; 0 05). Conclusion: Whole-stomach transplantation for the treatment of esophageal cicatricial stenosis and delayed gastric emptying do not persist. There is no need for additional pyloroplasty
