Carcinoid tumors of the ampulla of Vater grow slowly and have an excellent prognosis after complete resection of local disease. Histopathological diagnosis is definitive, and the Whipple's procedure is performed as a standard at the present time, although more novel minimally-invasive techniques may be highly useful for selected patients. While tumor size is not a reliable marker of tumor aggression, it is nonetheless related to lymphatic invasion, hence an accurate diagnosis is important if the patient is to be offered the best option available for the treatment of their disease...

The efficacy of lung metastasectomy is well established in several cancers, including colorectal cancer. However, little is known about the result of lung metastasectomy in carcinoma of the ampulla of Vater. Only two case reports have reported the efficacy of metastasectomy in ampullary cancer patients with pulmonary metastasis. We report the result of bilateral lung metastasectomy in a patient with ampullary cancer. A 63-year-old woman underwent pylorus-preserving pancreaticoduodenectomy for carcinoma of the ampulla of Vater...

The golden apple snail Pomacea canaliculata is an invasive pest originating from South America. It has already been retrieved in Asia, the southern United States and more recently in the EU. Aiming to target the immune system of the snail as a way to control its spreading, we have developed organ-specific transcriptomes and looked for molecules controlling replication and differentiation of snail hemocytes. The prokineticin domain-containing protein Astakine 1 is the only cytokine known thus far capable of regulating invertebrate hematopoiesis, and we analyzed the transcriptomes looking for molecules containing a prokineticin domain...

A 57-year-old woman with von Recklinghausen's disease presented with epigastralgia. Gastroduodenoscopy revealed swelling of the ampulla of Vater in the ventral and caudal direction, forming a hard, elastic mass. She was diagnosed with a tumor of the ampulla of Vater, and a subtotal stomach-preserving pancreaticoduodenectomy and D2 lymph node dissection were performed. The isolated specimen showed an intra-ampullary tumor of the ampulla of Vater and a submucosal tumor in the descending duodenum, which were diagnosed as a somatostatin-producing neuroendocrine tumor and gastrointestinal stromal tumor, respectively, on pathological examination...

INTRODUCTION: Although preoperative therapy is increasingly administered to patients with pancreatic adenocarcinoma, the role of preoperative therapy for patients with adenocarcinoma of the ampulla of Vater is undefined. METHODS: All patients with ampullary cancer who were evaluated between 1999 and 2014 were retrospectively reviewed. Differences in clinicopathologic characteristics, perioperative complications, and overall survival were compared between patients who underwent surgery de novo and those who received preoperative therapy before pancreatoduodenectomy...

Small bowel tumors are rare tumors. Duodenal tumors occur more commonly compared with other small intestinal tumors. To summarize the clinicopathological features of duodenal tumors, in the present study 44 cases of duodenal tumors were collected, and the comparative clinicopathological characteristics between tumors of the ampulla and non-ampulla, the choice of treatment, and differences in the prognosis, were analyzed. The pathological type identified was predominantly adenocarcinoma; periampullary duodenal tumors were almost classifiable as adenocarcinoma in terms of their type...

The vestibular blood-labyrinth barrier (BLB) is comprised of perivascular-resident macrophage-like melanocytes (PVM/Ms) and pericytes (PCs), in addition to endothelial cells (ECs) and basement membrane (BM), and bears strong resemblance to the cochlear BLB in the stria vascularis. Over the past few decades, in vitro cell-based models have been widely used in blood-brain barrier (BBB) and blood-retina barrier (BRB) research, and have proved to be powerful tools for studying cell-cell interactions in their respective organs...

Device selection and procedural guidance for percutaneous ductal closure strongly rely upon angiographic and echocardiographic imaging. Current literature recognises 2D echocardiography as an essential tool for diagnosis and assessment but does not define a consistent methodology to optimise ductal measurement. There is little research comparing echocardiography with gold standard angiography for ductal measurement. Proving 2D echocardiographic ductal measurement to be equivalent to angiography could pave the way for its use as the primary modality in image guidance for percutaneous closure of the ductus...

BACKGROUND AND AIMS: Biopsy of the ampulla of Vater may be performed to evaluate for ampullary adenomas, suspected ampullary tumors and immunohistological staining for autoimmune pancreatitis. Ampullary biopsies are commonly performed at the time of endoscopic retrograde cholangiopancreatography (ERCP). Due to the well-established complication rate following ERCP, the contribution of ampullary biopsy as a potential independent risk factor would require a controlled comparison. METHODS: A matched-pairs, case-control analysis was performed for patients undergoing ERCP with or without ampullary biopsy...

Undifferentiated carcinoma of the ampulla of Vater is a rare disease with unclear and clinical characteristics and prognosis. Here, we report the case of a 61-year-old man with undifferentiated carcinoma of the ampulla of Vater. He presented to our hospital with an increase in hepatobiliary system enzymes that was detected during a health check-up. Imaging and endoscopy demonstrated a tumor with ulcer in the ampulla of Vater, which was diagnosed as a carcinoma by biopsy. No distant metastasis was observed. Subtotal stomach-preserving pancreaticoduodenectomy was performed...

Mammalian spermatozoa undergo selective movement along the isthmus of the oviduct to the ampulla during ovulation, which is a prerequisite for fertilization. The factor(s) that involves in selective spermatozoa movement is still unknown. In this study, we found that the oviductal epithelium in mouse ampulla expressed high levels of natriuretic peptide type C (NPPC) in the presence of ovulated oocyte-cumulus complexes (OCCs). Spermatozoa expressed NPPC receptor natriuretic peptide receptor 2 (NPR2, a guanylyl cyclase) on the midpiece of flagellum...

BACKGROUND: The new method described here is highly efficient in transferring microinjected mouse eggs (MEs) through the bursa membrane of a surrogate mother mouse to the ampulla of the oviduct without damaging the blood vessels on the bursa membrane. RESULTS: This method causes no loss of blood, and it produces newborn pups/founders from approximately 70% of the transferred MEs, because only a small hole is made on the blood vessel-free area of the bursa membrane and ampulla of the surrogate mother mouse...

Carcinoma of the ampulla of Vater associated with annular pancreas is a rare entity. Only seven cases have been reported so far in the English literature. We herein report one such case in a 42-year-lady who presented with progressively increasing jaundice and pain in the upper abdomen for past 2 months. A magnetic resonance cholangiopancreaticography (MRCP) and MRI revealed an annular pancreas with an ampullary mass and a dilated CBD. An upper gastrointestinal endoscopic biopsy from the ampullary mass revealed a moderately differentiated adenocarcinoma...
