胆囊息肉样病变常见于无症状患者。本研究首次用超声检查法对胆囊息肉样病变的自然史进行了研究。 方法:1988年4343例门诊患者中B超检查发现111例有胆囊息肉样病变,其中2例有胆囊癌,其余109例列人观察。以后B超随访每年1～2次,共5年,记录息肉数目与最大息肉的直径。胆囊息肉样病变的诊断标准为,由囊壁突向囊腔的无声影不移动的回声。 结果:61%患者有多个息肉样病变,39%为 Gallbladder polypoid lesions are common in asymptomatic patients. For the first time in this study, the natural history of polypoid lesions in the gallbladder was studied by ultrasonography. METHODS: Among 4343 outpatients in 1988, 111 cases of gallbladder polypoid lesions were detected by B-ultrasound, of which 2 cases had gallbladder carcinoma and the remaining 109 cases were observed. After B-ultrasonography was followed up for 1 or 2 times a year for 5 years. The number of polyps and the diameter of the largest polyp were recorded. The diagnostic criteria for polypoid lesions of the gallbladder are the absence of acoustic shadows from the cyst wall toward the cyst. Results: 61% of patients had multiple polypoid lesions, 39% were
