Adenomas are frequently encountered in the lower digestive tract but are rarely diagnosed in the biliary tree. We report a case of villous adenoma of the common hepatic duct. A 58-year old male was admitted with a four week history of intermittent upper right quadrant pain. Gray scale and contrast-enhanced abdominal ultrasound showed a mass inside the common hepatic duct with arterial enhancement and slow wash-out during the late venous phase. Subsequent endoscopic retrograde cholangiopancreatography and intraductal ultrasound confirmed the presence of the lesion. The final histopathological examination showed villous adenoma of the common hepatic duct with high-grade dysplasia. Contrast enhanced ultrasonography used in conjecture with endoscopic retrograde cholangiopancreatography can help in differentiating biliary tumors. [ABSTRACT FROM AUTHOR]

Ultrasonography is generally accepted and performed as a first choice imaging technique in patients with jaundice. The method allows the discrimination between cholestatic and mechanical jaundice. The existing procedures are multiple: gray scale, Doppler, i.v. contrast enhancement, elastography, tridimensional ultrasonography, each of these with different contribution to the positive and differential diagnosis regarding the nature of the jaundice. The final diagnosis is a multimodal one and the efficiency is dependent on the level of the available technology, the examiner's experience, the degree and modality of integration of the data within the clinical context, as well as on the portfolio of available imaging procedures. This review shows the main ultrasonographic methods consecrated in the evaluation of the biliary tree. It also underlines the integrated character of the procedures, as well as the necessity to correlate with other imaging methods and the clinical situation. [ABSTRACT FROM AUTHOR]

Background & Aims: Diverticular disease of the colon is a common clinical condition in developed countries, and is associated with significant (direct and indirect) economic burden. The aim of this Position Paper is to provide clinical guidance for appropriate definition, prevalence, risk factors, diagnosis, and treatment of colonic diverticular disease. Methods: A working group of recognized experts established by the Board of the Romanian Society of Gastroenterology and Hepatology (RSGH) screened the literature and the available guidelines on colonic diverticular disease. Statements were formulated based on literature evidence. These statements were discussed within the working group and decision for each of them was taken by consensus. Results: Thirty two statements were elaborated. The grade of recommendation, according to the level of evidence was established for each statement. Short comments with literature support accompany each statement. Conclusion: This Position Paper represents a practical guide for clinicians dealing with patients affected by colonic diverticular disease. [ABSTRACT FROM AUTHOR]

The hamartomatous polyps in Peutz-Jeghers syndrome may have malignant potential. To differentiate between hamartomatous and adenomas polyps, vascular characterization can be assessed using noninvasive procedures, such as contrastenhanced ultrasound (CEUS). The neo-angiogenic characteristics of colorectal adenomas and carcinomas are expressed as an anarchic vascular pattern observed on CEUS. Using CEUS in a patient with Peutz-Jeghers syndrome, we describe for the first time the vascularization of a hamartomatous colonic polyp that exhibits a hierarchy branching pattern.
