Ampulla of Vater is a peculiar anatomical structure, characterized by the crossroad of three distinct epithelia: Intestinal, ductal pancreatic and biliary. Adenocarcinomas arising in this area represent an opportunity to understand the comparative biology of all periampullary malignancies. These neoplasms can exhibit intestinal, pancreaticobiliary or mixed features, whereas the subclassification based on morphology and immunohistochemical features failed in demonstrating a robust prognostic reliability.

Radiofrequency ablation (RFA) acts by delivering thermal energy within the tissue, the result of a high-frequency alternating current released from an active electrode, leading to coagulative necrosis and cellular death. Recently, a biliary catheter working on a guide-wire has been developed and a number of studies have been performed so far. The present paper provides a comprehensive review of the literature on the results of the use of RFA for the clinical management of patients with unresectable malignant biliary strictures, benign biliary strictures, and residual adenomatous tissue in the bile duct after endoscopic papillectomy.

The diagnostic and treatment guidelines of superficial non-ampullary duodenal tumors have not been standardized due to their low prevalence. Previous reports suggested that a superficial adenocarcinoma (SAC) should be treated local resection because of its low risk of lymph node metastasis, whereas a high-grade adenoma (HGA) should be resected because of its high risk of progression to adenocarcinoma. Therefore, pretreatment diagnosis of SAC or HGA is important to determine the appropriate treatment strategy. Read More

Identifying the accurate origin of periampullary cancers is important, because different origins may trigger different clinicopathologic behaviors. The presence of intraepithelial precursor lesions, including high-grade pancreatic intraepithelial neoplasias (PanINs) and/or high-grade biliary intraepithelial neoplasias (BilINs), may be suggestive of the origin of the periampullary carcinoma in challenging cases. To prove the usefulness of high-grade intraepithelial precursor lesions to identify the origin of ambiguous periampullary cancers, the status and grades of PanINs and BilINs were evaluated in 256 periampullary carcinomas with a well-defined cancer origin as a test set, including 114 pancreatic cancers, 82 distal bile duct cancers, 54 ampullary cancers, and 6 duodenal cancers, and 112 periampullary carcinomas with clinically equivocal epicenter either by radiologic imaging used as a validation set.

Herein, we report for the first time a case of a surficial superficial non-ampullary duodenal cancer causing obscure intestinal bleeding that was identified by small-bowel capsule endoscopy and treated by endoscopic mucosal resection. A 73-year-old man underwent upper gastrointestinal endoscopy to identify the cause of anemia. Although conventional duodenoscopy revealed a flat, elevated 5-mm lesion with a central recess and "milk-white mucosa" at the inferior duodenal angulus, capsule endoscopy revealed a white nodular 5-mm lesion with central recess at the duodenum slightly to the anal side from the major duodenal papilla.

Systemic inflammatory-, immunological- and nutritional-based indices, such as the neutrophil-to-lymphocyte ratio (NLR), the prognostic nutritional index (PNI) and the Glasgow prognostic score (GPS), are drawing considerable research attention to predict the long-term prognosis of many types of cancer. Recently, these parameters have also been reported to be useful in predicting postoperative morbidity in several fields, including colorectal and otolaryngological cancer. However, while distal cholangiocarcinoma exhibits a high morbidity rate, its risk factors of morbidity have not yet been established. Read More

Circulating tumor cells (CTC) enter the blood from many carcinomas and represent a likely source of metastatic dissemination. In contrast to the peripheral circulation, KRAS mutation- positive CTC thrive in the portal venous blood of patients with pancreatic ductal adenocarcinoma (PDAC). To analyze the essential interactions that contribute to carcinoma CTC growth and immune resistance, portal venous blood was collected during pancreatico-duodenectomy in 41 patients with peri-ampullary pathologies (PDAC = 11; ampullary adenocarcinoma (AA) = 15; distal cholangiocarcinoma (CC) = 6; IPMN = 7; non-malignant pancreatitis = 2).

Background: Diagnosing pancreatic ductal adenocarcinoma (PDAC) in the setting of metastasis with an unknown primary remains very challenging due to the lack of specific biomarkers. HNF-1B has been characterized as an important transcription factor for pancreatic development and was reported as a biomarker for clear cell subtype of PDAC.
