目的：应用核素显像技术，观察贲门失弛症Ｈｅｌｌｅｒ术后病人的食管通过功能。方法：口服含１８５ＭＢｑ９９ｍＴｃ－ＤＴＰＡ桔汁溶液１０ｍｌ，测定５分钟内的食管放射性计数，计算食管清除率。结果：Ｈｅｌｌｅｒ术后病人食管清除率明显优于术前组，但又显著低于正常对照组。结论：Ｈｅｌｌｅｒ手术能够改善贲门失弛症病人的食管通过功能，但不能达到正常人水平。
OBJECTIVE: To observe the esophageal passage function of Heller patients with cardia after ache with radionuclide imaging. Methods: Oral administration of 10ml of 185MBq99mTc-DTPA orange juice was used to determine esophageal radioactivity within 5 minutes and calculate esophageal clearance rate. Results: Heller patients esophageal clearance rate was significantly better than the preoperative group, but significantly lower than the normal control group. Conclusion: Heller operation can improve esophageal passage function in patients with cardia-achalasia, but can not reach the normal level.
