B超诊断胆囊息肉样病变359例分析

评价B超诊断胆囊息肉样病变（PLG）的临床价值。方法：作者对本院近14年手术治疗的359例PLG作回顾性分析。结果：表明B超检出PLG的敏感性为93．3％，其特异性达95．8％。B超诊断的病变的大小和病变的单发与多发，基本上与实际相符合。肿瘤性与非肿瘤性PLG的回声所见，以及良性肿瘤与恶性肿瘤的回声表现各有特点。结论：B超具有相当高的临床诊断价值，不仅能有效地检出PLG，而且能准确地测定病变的大及单发与多发，同时还能大体判别病变的性质。

B-ultrasonographic Diagnosis of Polypoid Lesions of the Gallbladder:An Analysis of 359 Cases

ObjeCtive To determine the clinical value of B-ultrasonography(US) in diagnosing polypoid lesions of the gallbladder (PLG). Methods: Three hundred and fifty-nine patients with PLG operated on at theFirst Affiliated Hospital of Zhejiang Medical University in recent 14 years were reviewed. ResultS:The sensitivityof US in the detection of PLG was 93. 3 % and its specificity was 95. 8%. The size and number of PLG measuredby US were consistent with those measured on the Postoperative macroscopic examination. The study also re-vealed that there were different characteristics in the ultrasound echoes not only between neoplastic and non-newplastic PLG, but also between benign and malignant tumors. Conclusion: US is of considerably reliable value inthe clinical investigation of PLG.
