胃溃疡的B超诊断研究

Study of Ultrasonographic Diagnosis in Gastric Ulcer

本文报告经手术、胃镜和病理证实的150例胃溃疡的B超检查结果。总检出符合率为82%,其中溃疡直径<0.5cm及≤1.5cm者良性溃疡分别占91%和81.8%;>1.5cm者恶性溃疡为79.2%。提出了小凹陷增厚型和大凹陷增厚型二种声像图类型,对漏误诊的原因进行了分析。作者认为,B超诊断本病无痛苦、经济、较可靠,是首选方法之一;对溃疡的性质,可根据凹陷的大小形态、胃壁增厚的范围、胃蠕动变化程度及胃周围有无淋巴结肿大和其它脏器有无浸润转移进行鉴别。

This Paper Presents the ultrasonographic diagnosis of 150 Cases with gastric ulcer proved by endoscopy,operation and patholgy. The overall Coincidence rate is 82% ,91% of those smaller than 0. 5cm and 81. 8% of those smaller than 1. 5cm are benign , uhereas 79. 2% of those larger than 1. 5cm are malignant. We put foward to small hollow -thick type sonogram and large hollow -thick type Sonogram. Causes of misdiagnosis are discussed. Ultrasonography is painless, reproducible, economical and reliable,so it is one of the preliminary examinations for gastric ulcer. The qualitative diagnosis can be based on the size and shape of the lesions,thickness of gastvic wall, alteration of movement, enlargement of lymph nodes as well as infitration and metastasis.
