肥厚性幽门狭窄的切面超声显像及价值

目的：认识肥厚性幽门狭窄（HPS）的切面图特征及超声诊断该病的价值。材料与方法：分析了17例经手术证实的HPS的临床及超声检查的资料，并与GI检查及手术所见加以对照。结果：超声诊断准确率为100％。切面图特征为右上腹助线下腹直肌外侧深部、胆囊内侧下方一右肾上极前方区域的纵切“宫颈征”和横切“靶环征”；7．0MHz扫查清楚显示狭长的幽门管和管内粘膜皱襞形成的“线条征”、“双轨征”及十二指肠球基底部幽门环肌肥大所形成的“肩征”。结论：超声诊断HPS具有特异性，较GI安全方便，可作为诊断本病的首选方法。

Value of Section Ultrasonic Imaging of Hypertrophic Pyloric Stenosis

Purpese: The paper discusses the character of the section of HPS and its ultrasonic dignosis. Materials and Methods: Careful analyse were made on 17 cases of HPS. examined by ultrasound method and proved by later operation. The findings were compared with those of GI examination and the operations. Results: The ultrasounic diagnostic accuracy rate is 100%. The character are as follows. Vertical cervis sign and transverse target sign were displayed among the areas of right upper abdomen, inferior lower coastal margin, lateral musculus rectus, inferior lower gallbladder and right upper kidney. 7. 0MHz scanning clearly display double - track sign in narrow pyloric canal and the plica mucosa and shoulder sign formed in the globular base of duodenurn. Conclusion: Ultrsound diagnosis of HPS have specific, which is safer and more convenient than GI examination, so it's the best method to diagnose HPS.
