Role of conventional ultrasonography in the diagnosis of gallbladder polypoid lesions

AbstractThe major role of conventional ultrasonography (US) can be divided into three processes: cancer screening, differential diagnosis, and assessment of the depth of tumor invasion. As US is a simple and minimally invasive modality, it is widely used for cancer screening and health checkups. Both gallbladder (GB) polyps and thickened wall of the GB are common US findings. On the contrary, US is prone to interference from gas echoes, and its diagnostic accuracy depends on both the US technology and the ability of sonographers. It is also important to be well acquainted with characteristic artifacts and how to manage their influence. Furthermore, magnified images acquired using high-resolution US (HRUS) are strongly helpful to pick up small lesions. As for differential diagnosis, classification of GB polypoid lesions (GPLs) into pedunculated or sessile (broad-based) types is very important. Cholesterol polyps in pedunculated lesions and localized adenomyomatosis (ADM) in sessile lesions are the most important targets to be differentiated. Furthermore, significant findings including number, size, growth rate, shape, internal echo, surface contour, and internal structure should be evaluated and judged as a whole. Usually, US delineates the GB wall as a two- or three-layer structure. However, as the inner hypoechoic layer includes not only the mucosa and muscularis propria but also the fibrous layer of subserosa, the differentiation between T1 (confined to the mucosa or muscul...

Conclusion: Advanced RCC has high morbidity and mortality with an increasing prevalence. Following tyrosine kinase inhibitors, checkpoint inhibitors have a great influence on treatment of advanced RCC, especially the combination of these two strategies. In 2019 these combined strategies demonstrated 5% complete remission with up to 60% objective response rate. While not immediately, but perhaps in the near future, advanced RCC will become a manageable chronic disease, even if a cure is not possible. PMID: 31942809 [PubMed - as supplied by publisher]

This study was performed to evaluate the relationship between body mass index (BMI) and acute and chronic cholecystitis, and cholecystitis and cholesterolosis. We investigated the clinical implications of BMI as a predictive factor of cholesterol associated cholecystitis. METHODS: This retrospective study covered the period from January 2007 to December 2011, we included 1,158 patients who had cholecystectomy. We excluded patients with gallbladder cancer, adenomyomatosis, and cholesterolosis without cholecystitis. Finally, we investigated the data of a total of 1,109 patients with cholecystitis. Laboratory test results...
