Genomic profile concordance between pancreatic cyst fluid and neoplastic tissue.

Background: DNA mutational analysis of pancreatic cystic fluid (CF) is a useful adjunct to the evaluation of pancreatic cysts. KRAS/GNAS or RAF/PTPRD/CTNNB1/RNF43 mutations are highly specific to precancerous or advanced neoplasia. Several studies recently demonstrated the ability of next-generation sequencing (NGS) analysis to detect DNA mutations in pancreatic CF, but few studies have performed a systematic comparative analysis between pancreatic CF and neoplastic surgical tissue (NT).

Endoscopic papillectomy for early ampullary tumors: long-term results from a large multicenter prospective study.

Background And Study Aims: Endoscopic papillectomy of early tumors of the ampulla of Vater is an alternative to surgery. This large prospective multicenter study was aimed at evaluating the long-term results of endoscopic papillectomy.

Patients And Methods: Between September 2003 and January 2006, 10 centers included all patients referred for endoscopic papillectomy and meeting the inclusion criteria: biopsies showing at least adenoma, a uT1N0 lesion without intraductal involvement at endoscopic ultrasound (EUS), and no previous treatment.

Virus-Associated Hemophagocytic Syndrome related to acute CMV and HBV sexual co-infection: a case report.

Background: Secondary or reactive hemophagocytic syndrome is frequently related to viral infections and is named Virus-Associated Hemophagocytic Syndrome (VAHS). Cytomegalovirus (CMV) has been associated with hemophagocytic syndrome in healthy subjects, patients with inflammatory bowel diseases rheumatologic diseases, and transplant recipients. CMV and hepatitis B virus (HBV) can be sexually transmitted.

Does chromoendoscopy with structure enhancement improve the colonoscopic adenoma detection rate?

Background And Study Aims: Colonoscopy is still considered the standard investigation for the detection of colorectal adenomas, but the miss rate, especially for small and flat lesions, remains unacceptably high. Chromoscopy has been shown to increase the yield for lesion detection in inflammatory bowel disease. The aim of this randomized prospective study was to determine whether a combination of chromoscopy and structure enhancement could increase the adenoma detection rate in high-risk patients.
