Diffuse gallbladder wall thickening on computed tomography in patients with liver cirrhosis: correlation with clinical and laboratory variables.

OBJECTIVES: The objective of the study was to retrospectively evaluate (a) which clinical/laboratory features are associated with the presence of diffuse gallbladder wall thickening (DGWT) in cirrhotic patients and (b) whether the degree of DGWT is correlated with such clinical/laboratory variables. METHODS: After excluding patients with DGWT or laboratory test abnormalities from known causes unrelated to liver cirrhosis, a retrospective review of liver computed tomography obtained from 242 consecutive cirrhotic patients was performed by 2 radiologists in consensus to determine the presence of DGWT of greater than 3 mm in thickness and, if present, to measure the degree of DGWT defined as maximal thickness. Univariate and multivariate analysis were performed to evaluate association between presence/degree of DGWT and clinical/laboratory features. RESULTS: Of 242 patients, 73 (30.2%) had DGWT. Diffuse gallbladder wall thickening was seen in 7.6% (12/157) of patients with Child-Pugh class A, 61.1% (33/54) of class B, and 90.3% (28/31) of class C (P < 0.001). The presence of ascites, lower platelet count, and lower albumin level were independently associated with the presence of DGWT (P < 0.01, P = 0.01, and P = 0.02, respectively). However, these factors did not show significant correlation with the degree of DGWT. CONCLUSIONS: The presence of DGWT in cirrhotic patients is associated with the presence of ascites, lower platelet count, and lower albumin level. The degree of DGWT is not correlated with such variables.
