高选迷切加保留胃窦部浆肌层半胃切除对胃运动功能的影响

Effects of highly selective vagotomy and antroseromuscular layer pylorus preserved hemigastrectomy on motility of gastric stump

目的 利用实验餐和放射性同位素显像技术研究高选迷切加保留胃窦部浆肌层的半胃切除术后胃运动功能。方法 将99mTC 植酸钠 6MBq加入黑芝麻糊 80g ,受试者 3min内服下 ,然后行放射性核素显像 ,得出胃排空曲线 ,计算 15、30、45、6 0和 90min胃排空率。结果 高选迷切加保留胃窦部浆肌层的半胃切除组与正常组比较无差异 ,而高选迷切组胃排空明显减缓。结论 高选迷切加保留胃窦部浆肌层的半胃切除术后胃运动功能不受影响 。

Objective To study the effects of highly selective vagotomy and antroseromuscular layer pylorus preserved hemigastrectomy on the motility of gastric stump.Methods Test meal and radioactive nucleotide imaging technique were used to observe the motility of the gastric stump. 80 g of black sesame paste containing 99m TC phytate 6MBq was ingested by the patient in 3 minutes and gastric imaging was performed immediately. Gastric emptying curve and emptying rate in 15,30,45,60 and 90 minutes were obtained.Results No significant difference of gastric emptying rate was detected between the patients with highly selective vagotomy and antroseromuscular layer pylorus preserved hemigastrectomy and those of the normal control but gastric emptying was significantly retarded in the patients with highly selective vagotomy as compared with the normal control.Conclusion There was little change of the motility of the gastric stump of the patients operated on with highly selective vagotomy and antroseromuscular layer pylorus preserved hemigastrectomy but gastric motility was usually impeded in patients operated on with highly selective vagotomy only.
