Emerging evidence shows that the human microbiota plays a larger role in disease progression and health than previously anticipated. Helicobacter pylori, the causative agent of gastric cancer and duodenal and gastric ulcers, was early associated with gastric disease, but it has also been proposed that the accompanying microbiota in Helicobacter pylori-infected individuals might affect disease progression and gastric cancer development. In this study, the composition of the transcriptionally active microbial community and the H...

Pancreaticobiliary maljunction is a congenital malformation in which the pancreatic and bile ducts join outside the duodenal wall, usually forming a long common channel. Because the action of the sphincter of Oddi does not regulate the function of the pancreaticobiliary junction in patients with pancreaticobiliary maljunction, two-way regurgitation occurs. Reflux of pancreatic juice into the biliary tract is associated with a high incidence of biliary cancer. Biliary carcinogenesis in patients with pancreaticobiliary maljunction is thought to follow the hyperplasia, dysplasia, then carcinoma sequence due to chronic inflammation caused by pancreatobiliary reflux...

A cancer bioassay on hexavalent chromium Cr(VI) in drinking water reported increased incidences of duodenal tumors in B6C3F1 mice at exposures of 30-180ppm, and oral cavity tumors in F344 rats at 180ppm. A subsequent transgenic rodent (TGR) in vivo mutation assay in Big Blue® TgF344 rats found that exposure to 180ppm Cr(VI) in drinking water for 28days did not increase cII transgene mutant frequency (MF) in the oral cavity (Thompson et al., 2015). Herein, we extend our analysis to the duodenum of these same TgF344 rats...

H. pylori is a Gram-negative extracellular bacterium, first discovered by the Australian physicians Barry Marshall and Robin Warren in 1982, that colonises the human stomach mucosa. It is the leading cause of peptic ulcer and commonly infects humans worldwide with prevalence as high as 90% in some countries. H. pylori infection usually results in asymptomatic chronic gastritis, however 10-15% of cases develop duodenal or gastric ulcers and 1-3% develop stomach cancer. Infection is generally acquired during childhood and persists for life in the absence of antibiotic treatment...

A man in his seventies underwent esophagogastroduodenoscopy, which revealed a 30-mm whitish protruding lesion at the descending part of the duodenum. Owing to the protrusion and reddish depressed area on the lesion, invasive cancer was suspected (Fig. 1A). Endoscopic ultrasonography (EUS) with a 20-MHz miniature probe (UM-3R, Olympus Medical Systems, Tokyo, Japan) revealed an intramucosal hypoechoic lesion and a thickened high echoic submucosal layer with acoustic attenuation (Fig. 1B).

Background:Helicobacter pylori infection is a known risk factor for duodenal ulcers, gastritis, and gastric cancer. The eradication of H. pylori is successful in treating these disorders; however, the success rate of eradication therapy is declining. There may be an interaction with nutrient intake to account for this decline.Objective: We investigated the influence of food and nutrient intake on H. pylori eradication therapy.Design: In this study, 4014 subjects underwent endoscopy, were tested for serum antibodies to H...

Gram-negative bacteria Helicobacter pylori (H. pylori) colonize gastric mucosa in humans and increase the risk of serious diseases such as gastric and duodenal ulcers, stomach cancers and mucosa associated lymphoid tissue lymphoma. The role of H. pylori infection in the pathogenesis of several extragastric diseases has been suggested including immune thrombocytopenic purpura, iron deficiency anemia, vitamin D deficiency, cardiovascular diseases, diabetes mellitus and dermatological disorders. Also neurological diseases and even lung cancer have attracted researchers concern...

The advancement of laparoscopic surgery serves as a trigger for better understanding of the vascular structure at the inferior border of the pancreas, especially Henle trunk. Henle trunk was first found as convergence to superior mesenteric vein (SMV) conjoined by sub-right colon vein (SRCV) and right gastroepiploic vein (RGEV), but decades later, anterior superior pancreatic duodenal vein (ASPDV) was described as another conjoint vein of Henle trunk. These tributaries are the basic elements of Henle trunk in early years' study...

With this report we alert to an extremely rare case of duodenal metastases, from an endometrial adenocarcinoma by lymphatic spread and whose primary manifestation was with gastrointestinal bleeding. We think this is the first case reported of duodenal metastases from endometrial carcinoma and with this presentation.

Globally, obesity is a leading cause of preventable death and is associated with >60 comorbid medical conditions, including 10 types of cancer that are strongly associated with body mass index. There are a number of traditional obesity treatments-for example, lifestyle management (eg, decreased caloric intake and increased expenditure), pharmacotherapy, and bariatric surgery. Recently, endoscopic approaches have emerged as a viable alternative for weight loss. Endoscopically placed intragastric balloons were introduced in the early 1980s for the treatment of medically complicated obesity but, unfortunately, had high rates of complications, such as premature deflation leading to obstruction...

Importance: Small-bowel adenocarcinomas (SBAs) are rare cancers with a significantly lower incidence, later stage at diagnosis, and worse overall survival than other intestinal-derived cancers. To date, comprehensive genomic analysis of SBA is lacking. Objective: To perform in-depth genomic characterization of a large series of SBAs and other gastrointestinal tumors to draw comparisons and identify potentially clinically actionable alterations. Design, Setting, and Participants: Prospective analysis was performed of clinical samples from patients with SBA (n = 317), colorectal cancer (n = 6353), and gastric carcinoma (n = 889) collected between August 24, 2012, and February 3, 2016, using hybrid-capture-based genomic profiling, at the request of the individual treating physicians in the course of clinical care for the purpose of making therapy decisions...

Distal malignant biliary obstruction (MBO) leads to obstructive jaundice as a result of when the bile excretion from the liver is disturbed and induces hepatic failure and sepsis, which when complicated with cholangitis, it becomes necessary to perform drainage for the MBO. For biliary drainage, we can perform a surgical bypass operation, percutaneous transhepatic biliary drainage (PTBD), endoscopic biliary drainage (EBD) via duodenal papilla, or endoscopic ultrasound (EUS)-guided biliary drainage (EUS-BD), which is a transgastrointestinal biliary drainage...

Pancreatic ductal adenocarcinoma (PDAC) is one of the cancers with poorest prognosis and represents the third leading cause of cancer-related deaths in Western countries. Despite advances in diagnostic procedures and treatment, diagnosis is made in most cases when the disease is locally advanced or metastatic. Supportive care aims to improve symptoms, reduce hospital admission rates, and preserve quality of life. Proper symptomatic management is critical to allow administration of chemotherapy and radiotherapy...

BACKGROUND: We aimed to clarify the utility of delta-shaped anastomosis (Delta), an intracorporeal Billroth-I anastomosis-based reconstruction technique used after laparoscopy-assisted distal gastrectomy (LADG), in robot-assisted distal gastrectomy (RADG). METHODS: RADG was performed in patients with clinical Stage I gastric cancer, and reconstruction was performed using Delta. The Delta procedure was the same as that performed after LADG, and the operator practiced the procedure in simulated settings with surgical assistants before the operation...

RATIONALE: Metastatic involvement of the gastrointestinal tract is an uncommon scenario encountered in the clinical practice. Our case represents a gastric outlet obstruction (GOO) as a consequence of distant Transitional cell carcinoma (TCC) metastasis without any lymph node involvement in association with inflammatory stranding leading to extrinsic duodenal obstruction. PATIENT CONCERNS: We report an unusual case of a 73-year-old male presented with a five-week history of nausea, vomiting and abdominal pain due to the metastatic extension from TCC that had been considered in remission...
