Gallbladder wall thickening can be measured in the short or long axis and should be measured at the thickest point along the wall; A number of normal states can also cause gallbladder wall thickening – including congestive states, ascites, and in the setting of a contracted gallbladder. Ultrasound findings must be interpreted in conjunction . Results: The relationship between the gall-bladder wall thickness and the occurrence of intraoperative difficulties in the analysed set is deterministic (AUC = 1), and the wall thickness of ≥ 5 mm allows to predict their occurrence as soon as at the stage of diagnostic evaluation (p < 0.001). In addition, the ultrasound-measured GB wall .

Measurement of gallbladder lesions. The examples in section 1 indicate that a reliable measurement of the thickness of the gallbladder wall is only possible in the hepatic wall. It is advisable to measure it on an enlarged sonogram using the zoom function (Fig. 12). Fig. 12. The purpose of this work was to evaluate, by ultrasonographic method, gallbladder wall thickness and gallbladder emptying after a standard meal in normal subjects and in patients with compensated liver cirrhosis without gallstones. Methods. Twenty-three patients with Child-Pugh class A liver cirrhosis and twenty healthy controls were studied.
A prospective ultrasound study of gallbladder wall thickness in patients with suspected gallbladder disease was performed over a 9 month period. Gallbladder walls thicker than 3 mm in fasting .
As the thin hyperechoic serosa is rarely discernible, bowel wall thickness is measured from the outer contour of the ventral muscularis to the outer contour of the dorsal muscularis, and then of course, divided by two. Normally, single small bowel wall thickness during compression is about 1.5 - 2.5 mm. The Gallbladder Reporting and Data System (GB-RADS) ultrasound (US) risk stratification is proposed to improve consistency in US interpretations, reporting, and assessment of risk of malignancy in gallbladder wall thickening in non-acute setting.

Each patient's preoperative evaluation included a gallbladder ultrasound, which included measurement of the diameter of the gallbladder wall. The entire series of cholecystectomies was evaluated according to the ultrasound measured diameter of the gallbladder wall. A thin gallbladder wall was less than 3 mm in diameter. The normal gallbladder wall appears as a pencil-thin line, with 3 to 4 mm being the upper limit of normal thickness for the anterior gallbladder wall. The anterior wall, closest to the transducer footprint, is measured due to an artifact called posterior acoustic enhancement leading to an artificially thick appearance of the posterior .
Differences of mean liver length, gallbladder wall thickness, inferior vena cava, portal vein, and pancreas between males and females. The differences of mean liver length, GBWT, IVC, PV, and pancreas between males and females were tested and illustrated in Table 2.The liver length was larger in males (12.2 ± 1.5 cm) than in females (11.7 ± 1.5 cm).To date, gallbladder wall thickness typically has been evaluated against an anecdotally reported measurement, without a formal evidence base. 4 Gallbladder wall thickness identified in our study is considerably less than the widely cited 3 mm value, 4 and more aligned with recent indirect evidence presented above 7, 8, 10 and the statement that .
