Abstract:
Objective To study the proportion and sonographic features of various kinds of diseases in the polypoid lesions of the gallbladder (PLG) diagnosed by ultrasonography, and to explore the reliability of ultrasonography for the diagnosis of PLG. Methods A total of 556 cases of PLG diagnosed by ultrasonography were classified basing on the results of pathological examination. And the accordance rate between ultrasonography and pathological examination in the PLG with different size was analyzed. Results Among the 556 cases of PLG, 446 (80.2%) had cholesterol polyps, 86 (15.5%) adenomatous polyps, 18 (3.2%) inflammatory polyps, and 6 (1.1%) myoadenoma. In 97.3% of the cholesterol polyps, the diameter was less than 1.0 cm, and 64.6% of the cases had multiple polyps. In the cholesterol polyps, the accordance rate between ultrasonography and pathological examination was 91.3%. Of the adenomatous polyps, 61.6% had a diameter over 1.0 cm, and 34.0% showed atypical hyperplasia or malignancy. However, 25% of the malignancies were found in the adenomatous polyps with a diameter less than 1.0 cm. Conclusions More than 80% of PLG are cholesterol polyps and 15.5% are adenomatous polyps. Most of the PLG with malignant transformation sized over 1.0 cm in diameter. However, the adenomatous polyps with a diameter ranged from 0.7 to 0.9 cm also have malignant tendency. In the cholesterol polyps, the accordance rate between ultrasonography and pathological examination is 91.3%, showing that ultrasonography is reliable for the diagnosis of the disease.
