核素显像对贲门失弛症术后食管通过功能的评价

ESOPHAGEAL SCINTIGRAPHY TO QUANTITATE ESOPHAGEAL TRANSIT OFTHE ACHALASIA AFTER HELLER'S MYOTOMY

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。

PURPOSE To quantitate esophaged transit of the achalasia patients after Heller's myotomy using scintigraphic technique. METHODS After a bolus ingestion of 10ml orange juice containing 185MBq 99mTc-DTPA,radioactivity was measured on the esophagus for 5 minutes by SPECT,and esophageal clearance rate was calculated.Fourly-two patients and 10 normal contrmal were included.RESULTS Esophageal transit was increased significantly after Heller's operation,but it was still lower than normal value.CONCLUSION Heller's myotomy can significantly improve esophageal transit in the patients with achalasia,although it does not reach normal level.
