Ultrasound diagnosis on the apophysis lesions of gallbladder / 国际外科学杂志

ABSTRACT

Objective To discuss the ultrasound diagnosis on the apophysis lesions of the gallbladder. Methods A retrospective analysis was made in 51 cases of polypoid lesions of gallbladder ultrasound char-acteristics of cases, clinical symptoms and pathological types. Results There were 43 cases of benign le-sious (39 cases of cholesterol polyp, 3 cases of adenomyosis, 1 case of inflammatory polyps), 8 cases of tumor lesions (5 cases of adenomatous polyp, 3 cases of malignant tumors). Among those patients with out clinical symptoms (n = 32) were for cholesterol polyps (P < 0. 05) while in, with symptomatic patients (21 cases), 8 were complicated with stone, 4 with ulcerative disease. Three cases (100%) with adenomyosis and 4 cases (80%) with adenomatous polyposis shouwed symptoms (P < 0. 05). Patients with multiple pol-ypoid lesions (22 cases), were benign lesions, and 95.5% were pathologlicdly cholesterol polyp. Seven ca-ses of ultrasound diagnosis of gallbladder polyps were pathologically diagnosed having polyp diameter smaller than 0.3 cm. Ultrasound showed gallbladder wall thickening in 6 cases, 3 with adenomyosis (wall thickness 0. 5 - 1.8 cm), 3 with malignant lesions in gallbladder (wall thickness 0. 5 - 1.2 cm). Conclusions For those patients ultrasound showed asymptomatic or multiple polyps of the gallbladder, cholesterol polyps are the most common type of lesion. Ultrasound is not sensitive to polypoid lesions of the gallbladder with diame-ter less than 0. 3 cm. Those with limited ultrasonic gallbladder wall thickening (>0. 5 cm) should pay more attention to the possibility of having malignant tumors and adenomyosis.
