摘 要: | 42 cases of dilatation (7-15 mm) of extrahepatic bile duct after ceosunin injection (cholagogic method) were observed ultrasonographically. Among the 18 cases of testified obstructive lesions of the bile duct, 13 (72%) showed widening of the bile duct with an increase of calibre from 9.8 mm to 11.7 mm, 3 (16%) had no obvious change, and 2 (12%) shrank. Among the 24 cases of non-obstruction 22 (92%) shrank with a decrease calibre from 9.6 mm to 6.3 mm, and 2 (8%) showed no obvious change. After receiving cholagogue, 9 cases of periampullary carcinoma in the obstructive group were confronted with widening of the bile duct calibre. After longitudinal and transverse rotation scanning method was used, 8 of the 9 cases had their tumor mass visualized. Combined cholagogic and rotation scanning methods raised the lesion manifestation rate of lower bile duct from 41% to 88%. A dilated bile duct unable to show shrinkage of calibre after cholagogue injection is believed to be a criterion for judging the presence of
