- Gallbladder cancer is rare but serious, making early detection of precursors important; this study focuses on gallbladder polyp prevalence and the effectiveness of ultrasound in diagnosis in a western European population.
- Data was collected from 134 patients who had surgery due to ultrasound-detected gallbladder polyps, revealing that most were benign (pseudopolyps), with only 4.5% being dysplastic or malignant.
- The study found that the positive predictive value of ultrasound for detecting neoplastic polyps was only 4.5%, lower than previously reported rates, highlighting a need for better detection methods and possibly reducing unnecessary surgeries.
