복부초음파검사로 진단된 담낭의 용종양 병변의 임상적 의의

Abstract

Polypoid lesions of the gallbladder can be seen by using abdominal ultrasonography in clini- cal practice frequently at present. Nevertheless, the nature of polypoid lesions of the gallblad- der is diffcult to define before operation. The aim of this study were to evaluate the clinical and ultrasonographic findings and to determine the surgical indications of polypoid lesions of gallbladder. Review of X Ray of ultrasonography was available in 327 cases with polypoid le- sions of the gallbladder diagnosed by ultrasonography from January 1990 to June 1993 at Sev- erance Hospital of Yonsei Medical Center. Most of cases of polypoid lesions of gallbaldder were asymptomatic. The surgical indications of 35 cases were symptornatic lesions in 23 cases, suspicion of cancer in 10 cases and association of gallstone in 2 cases. Final diagnosis were benign polyp in 26 cases, malignant polyp in 4 cases and gallstone in 5 cases. The benign polyps were smaller in the size(less than 1.0cm in diameter) than the malignant polyps(larger than 1.0cm in diameter) and found in younger age than the malignant polyp(over 60 years old). In conclusion, operation should be performed for polypoid lesions of gallbladder exceeding 1.0cm in diameter and over 60 years old cases
