Adenoma of the gallbladder is vary rare pathologic condition and small in size, usually discovered incidentally during the laparotomy or diagnostic procedure for other intraabdominal lesions. Fifteen cases of the gallbladder adenoma adenoma were
found
from 1982 to 1993 at Department of Surgery, Masan Koryo General Hospital, The incidence of gallbladder adenoma to cholecystectomy during the same period was 0.76%(15 : 1985). The male to female-ratio was 1 : 3.7 and the peak incidence was 6th
decade.
Pertaining to size, seven cases, were less than 10mm in diameter, three were 10 to 14mm and remained five were larger than 15mm. For investigating gallbladder adenoma, ultrasonography was a highly sensitive method (sensitivity: 53.3%). There was
a
cases
of adenoma with focal adenomatous carcinoma, but no definite evidence of sequence suspecting malignant change from the underlying adenoma. In conclusion, the ultrasonography was a standard imaging technique in the preoperative diagnosis and
assessing
the surgical indications of the gallbladder adenoma, and there had been no definite malignant evidence in our cases.(Korean J Gastroenterol 194 ; 26 : 981-986)
