Overview
According to the NCCN guidelines, screening for gallbladder cancer patients is recommended with endoscopic ultrasongraphy (EUS)
Gallbladder cancer ultrasound
- when gallbladder pathology is suspected ultrasonography is most commonly the first choice for screening.
- Sensitivity and specificity of ultrasound screening is 85% and 80%.
- A High-resolution contrast-enhanced ultrasonography identifies up to 70–90% of polypoid gallbladder lesions.[1]
- Gallbladder cancer on ultrasound have one of the following feartures[2]
- 1) A mass in the gallbladder
- 2) A polyp in the gallbladder
- 3) Asymmetric wall thickening of the gallbladder
- Polyps which are over 1 cm in diameter have higher chance to contain an invasive cancer than smaller ones.[3]
- With Contrast-enhanced ultrasonography gallbladder cancer shows an “eruption sign”[4]
