We report a case a 70-year-old female presenting with abdominal pain who has a cystic duct coursing medial to the common bile duct before anastomosing just proximal to the ampulla. Low medial insertion of the cystic duct is a rare anatomic variant that is easily misidentified on imaging studies and may complicate surgical and percutaneous intervention. It can be identified by pre-operative imaging modalities such as magnetic resonance cholangiopancreatography.

Gangliocytic paraganglioma is an uncommon tumor, which is usually located in the ampulla of Vater, and may get confused in the differential diagnosis with ampuloma or GIST. Here we present a case of a patient with upper gastrointestinal bleeding as a predominant symptom, objectified by endoscopy an ulcerative polypoid mass at the juxtapilar level, with histological result of gangliocítica paraganglioma after multiple biopsies, and finally surgical resection. The interest of this case is the difficulty for diagnosing, the different treatments and prognosis that this implies, especially for the tumor location, as surgery can lead to great complications...

Biliary tract cancer (BTC) is one of the most devastating types of malignant neoplasms worldwide. However, the mechanisms underlying the development and progression of BTC remain unresolved. BTC includes extrahepatic bile duct carcinoma (EBDC), gallbladder carcinoma (GBC) and ampulla of Vater carcinoma (AVC), named according to the location of the tumor. Although genetic alterations of intrahepatic cholangiocarcinoma have been investigated, those of EBDC, GBC and AVC have not yet been fully understood. The present study analyzed somatic mutations of 50 cancer-associated genes in 27 Japanese BTC cells, including: 11 EBDC, 14 GBC and 2 AVC...

BACKGROUND AND STUDY AIMS:  Findings in the literature are conflicting on whether trainee involvement in endoscopic retrograde cholangiopancreatography (ERCP) procedures is detrimental to cannulation success rates. We addressed this in a prospective study, where cannulation success with or without trainee presence was the primary outcome measure. PATIENTS AND METHODS:  We prospectively recorded data on 2 senior endoscopists and their trainees over an 18-month period for ERCPs in patients with a virgin ampulla...

In cattle, the oviduct plays a fundamental role in the reproductive process. Oviductal functions are controlled by the ovarian sex steroids: estradiol and progesterone. Here, we tested the hypothesis that the exposure to contrasting sex steroid milieus differentially impacts the oviductal transcriptional profile. We manipulated growth of the pre-ovulatory follicle to obtain cows that ovulated a larger (LF group) or a smaller (SF group) follicle. The LF group presented greater proestrus/estrus concentrations of estradiol and metaestrus concentrations of progesterone (Gonella-Diaza et al...

Brunner's gland cysts are rare, benign lesions of the duodenum usually seen as incidental, polypoid or cystic lesions of the duodenum. We present a series of 25 cases of Brunner's gland cyst, the largest case series to date. All the cases were identified during endoscopic assessment for unrelated causes. The mean age of the patients was 66.2 years and the sex ratio was approximately equal. Most were detected as a small (3-10 mm) polypoid lesion in the second part of the duodenum, away from the ampulla. Most of the cysts were unilocular and all were lined by undulating, cytologically bland cuboidal to columnar cells with clear cytoplasm and small, basal nuclei...

INTRODUCTION: The ampulla of Vater consists of papilla, common channel, distal common bile duct and the distal main pancreatic duct. Ampullary carcinomas arise from two different types of mucosa, reflecting their broad histomorphological spectrum. Adenocarcinomas originating in the ampulla of Vater are classified as having either 'Intestinal' or 'Pancreatobiliary' type of differentiation. Pancreatobiliary type has consistently shown a worse prognosis. Various types of mucins are distributed in normal tissues and gastrointestinal tumours...

Parasitic disease is among the major causes of health problems in marine mammals. However, little information on parasitic species composition and infection levels in finless porpoises (Neophocaena spp.) is available. In this study, we report the first systematic survey on parasitic infections in the East Asian finless porpoise N. asiaeorientalis sunameri (EAFP) living off the Chinese Yellow/Bohai Sea coast. Using both morphological and molecular methods, 5 parasitic helminths were identified: Campula oblonga in the liver and pancreas; Synthesium seymouri in the pyloric stomach and duodenum ampulla; Anisakis pegreffii in the forestomach, main stomach, and esophagus; Halocercus sp...

Pancreaticobiliary maljunction (PBM) is a congenital malformation that is associated with biliary cancer development. When patients are diagnosed with PBM, a diversion operation is recommended. Although a risk remains for developing residual bile duct carcinoma following diversion, the development of a carcinoma of the ampulla of Vater after a diversion operation for PBM is rare. We present a treated case of carcinoma of the ampulla of Vater after a diversion operation for PBM. A 65-year-old woman presented with abdominal pain...

Unidirectional flow of oviductal fluid from the ovarian to uterine side of the ampulla plays a significant role in successful pregnancy, and is produced by ciliary beating. Various systems regulate ciliary beating, such as paracrine, autocrine, and endocrine. We hypothesized that Adrenomedullin (ADM) - a peptide hormone that acts via its receptors, which are complexes of Calcitonin receptor-like receptor (CRLR) and Receptor activity-modifying protein (RAMP) 2 or 3-promotes oviductal fluid flow in the ampulla of bovine oviducts...

Afferent loop syndrome (ALS) is a rare complication of Billroth-II gastrojejunostomy. Causes of afferent loop obstruction include adhesions, internal hernias, intestinal strictures or malignancy. Obstruction caused by enteroliths is rare and usually requires surgery. We present the case of a 90-year-old man with a Billroth-II performed 50 years earlier and three acute pancreatitis. He presented with acute abdominal pain, without signs of pancreatitis. Upper digestive endoscopy revealed a punctiform anastomotic stricture of the afferent loop...

Portal hypertensive biliopathy (PHB) is described as abnormalities of the walls of the biliary tree secondary to portal hypertension. Gastrointestinal bleeding caused by PHB is rare. PHB as a cause of serious bleeding after sphincteroplasty during ERCP is extremely rare. Here, we report a case of PHB in a young Saudi male with cell sickle anemia who developed massive hemorrhage during ERCP after balloon dilation of the ampulla of Vater. We further discussed the diagnosis and management. To the best of our knowledge, no such case has been reported...

Ovulation and oocyte-pick-up are essential processes in fertilization. Herein, we found associations between autoimmune disease and the aforementioned processes in mice. At three and six months, along with the evaluation of autoimmune disease indices, the ovary, mesosalpinx, and oviducts were histologically examined in C57BL/6, MRL/MpJ, and MRL/MpJ-Fas (lpr/lpr) mice as healthy control, mild and severe models of autoimmune disease, respectively. In superovulated mice, the number of "oocyte cumulus complexes" found in the ampulla was macroscopically counted, and that of "ovulated oocytes" was histologically evaluated, as indicated by ruptured follicles or corpora hemorrhagica in ovaries...

Rough environmental conditions make the survival of many multi-cellular organisms almost impossible, enforcing behavioral, morphological, physiological and reproductive rejoinders that can cope with harsh times and hostile environments, frequently through down-regulation of metabolism into basal states of dormancy, or torpor. This study examines one of the most unique torpor strategies seen within the phylum Chordata, exhibited by the colonial urochordate Botrylloides leachi, which enters a state of hibernation or aestivation in response to thermal stress, during which all of its functional colonial units (zooids) are entirely absorbed and the colony survives as small remnants of the vasculature, lacking both feeding and reproduction organs...

BACKGROUND: Delayed gastric emptying (DGE), a common postoperative complication of pancreaticoduodenectomy, is not considered a life-threatening complication. In the present study, we analyzed the risk factors for DGE and its impact on long-term prognosis. METHODS: We analyzed 383 patients who underwent pancreaticoduodenectomy between 2003 and 2010, dividing them into two groups according to DGE grade as defined by the International Study Group of Pancreatic Surgery: 243 without DGE (non-DGE group) and 140 with DGE of any grade (DGE group)...
