Objectives:
To investigate the clinical, pathological, and sonographic characteristics of unexpected gallbladder carcinoma (UGC).
Methods:
Of 5424 patients who had undergone cholecystectomy from December 2006 to October 2013, 54 patients with primary gallbladder carcinomas confirmed by pathological diagnosis were identified. The patients were divided into two groups: diagnosed before operation (n=34) and UGC groups (n=20), of whom the clinical, pathological, and sonographic characteristics were compared.
Results:
No significant differences in age, gender, location of lesion, histological type, length of the gallbladder, existence of biliary sludge, and intestinal gas interference between the two groups were found (all P>0.05). The clinical symptoms, laboratory abnormalities, tumor markers, coexisting gallbladder stones, lesion size, lesion type, degree of differentiation, and tumor staging showed statistically significant differences between the two groups (all P<0.05). On ultrasound, the width of the gallbladder, gallbladder wall thickness, vascularity on color Doppler ultrasound, and bile volume in the gallbladder showed significant differences (all P<0.05).
Conclusions:
UGCs are commonly found at an early stage, often well-differentiated, wall thickened, and are generally accompanied with cholelithiasis. UGCs should be taken into consideration in cases with cholelithiasis or small gallbladder on ultrasound.
