We have updated both the American College of Gastroenterology (ACG) and the Canadian Association of Gastroenterology (CAG) guidelines on dyspepsia in a joint ACG/CAG dyspepsia guideline. We suggest that patients ≥60 years of age presenting with dyspepsia are investigated with upper gastrointestinal endoscopy to exclude organic pathology. This is a conditional recommendation and patients at higher risk of malignancy (such as spending their childhood in a high risk gastric cancer country or having a positive family history) could be offered an endoscopy at a younger age...

INTRODUCTION: In esthesioneuroblastoma, greater disease extent and Kadish staging correlate with greater recurrence, complications, and mortality. These advanced stage malignancies require extensive resections and aggressive adjuvant therapy. This increases the risk of complications such as cerebrospinal fluid leak, neurologic deficits, and osteomyelitis. We present our case series and then analyze the literature to ascertain whether advanced stage tumors corresponds to greater rates of complications...

BACKGROUND: Whether gastric hyperchlorhydria and Helicobacter pylori infection contribute to aspirin-induced gastroduodenal injury still lacks evidence. Because serum pepsinogens (PGs) and gastrin-17 (G17) can reflect gastric acid secretion, this study intended to elucidate whether serum PGs, serum G17, and H. pylori infection are associated with aspirin-induced gastrointestinal injury. SUMMARY: A total of 60 patients taking low-dose aspirin for more than 1 month were enrolled in this study...

Gastric cancer (GC), one of the five most common causes of cancer death, is associated with a 5-year overall survival rate less than 30%. A minority of cancers occurs as part of syndromic diseases; more than 90% of adenocarcinomas are considered as the ultimate consequence of a longstanding mucosal inflammation. H. pylori infection is the leading etiology of non-self-limiting gastritis, which may result in atrophy of the gastric mucosa and impaired acid secretion. Gastric atrophy establishes a field of cancerization prone to further molecular and phenotypic changes, possibly resulting in cancer growth...

AIM: To investigate the association between a recent gastrointestinal (GI) endoscopy and the subsequent risk of pyogenic liver abscess (PLA). METHODS: We designed a nested case control study. Using the Taiwan National Health Insurance Research Database, 2135 patients with a first diagnosis of PLA were identified from 1998 to 2011. Another 10675 patients without PLA matched by age and sex were selected as reference controls. We identified and compared the possible risk factors for PLA and GI endoscopies performed before the index date (when PLA was diagnosed) between the two cohorts...

Esophageal leaks (EL) and ruptures (ER) are rare conditions associated with a high risk of mortality and morbidity. Historically, EL and ER have been surgically treated, but current treatment options also include conservative management and endoscopy. Over the last decades, interventional endoscopy has evolved as an effective and less invasive alternative to primary surgery in these cases. A variety of techniques are currently available to re-establish the continuity of the digestive tract, prevent or treat infection related to the leak/rupture, prevent further contamination, drain potential collections, and provide nutritional support...

Helicobacter pylori (H. pylori) infection is one of the major causes of bleeding peptic ulcer disease, which is associated with serious complications; therefore, the eradication of H. pylori is essential to prevent these devastating complications. Post-treatment follow-up is crucial to guarantee the eradication of the organism and may be conducted via the urea breath test, the stool antigen test, or a gastric biopsy. Acute massive upper gastrointestinal (UGI) bleeding is one of the most common complications of peptic ulcer disease...

H. pylori, a spiral gram-negative bacterium, is associated with gastroduodenal diseases. All H. pylori diagnostic assays have limitations. Cytotoxin-associated gene A (cag A), a virulence marker, can be identified by PCR. We evaluated H. pylori diagnostic methods, invasive: rapid urease test (RUT), and histopathological examination (HE), and serology as non-invasive method. Positive cases were studied for presence of cag A gene. Upper endoscopies and gastric biopsies were performed on 67 dyspeptic patients for RUT, HE and PCR...

BACKGROUND: The randomised controlled ASTIC trial showed no benefit of mobilisation and autologous haematopoietic stem-cell transplantation (HSCT) compared with mobilisation followed by conventional therapy using a stringent primary endpoint (steroid-free clinical remission for 3 months with no endoscopic or radiological evidence of intestinal inflammation) in patients with treatment-refractory Crohn's disease. We now assess HSCT in patients enrolled in the ASTIC trial using endpoints that are traditional for clinical trials in Crohn's disease, and identify factors that predict benefit or harm...

Xanthogranulomatous pyelonephritis (XGP) is a rare form of pyelonephritis associated with repeated infection, chronic inflammation, and obstruction. Various fistulas, including those to the intestine, are a known association with XGP. Here, a 55-year-old woman with a history of multiple previous renal calculi presented with dysuria and back pain. Contrast-enhanced computed tomography (CT) revealed a soft tissue density in her renal pelvis and perirenal space consistent with XGP along with a tract connecting the upper pole of her right kidney to the second portion of the duodenum...

HIV infection is reportedly associated with an increased permeability of the intestinal epithelium and can cause HIV enteropathy, which occurs independently of opportunistic infections. However, the characteristics of small bowel abnormalities attributable to HIV infection are rarely investigated. In the present study, we assessed the intestinal mucosal changes found in HIV-infected patients and compared them with the mucosa of healthy control subjects using capsule endoscopy (CE). Three of the 27 HIV-infected patients harbored gastrointestinal opportunistic infections and were thus excluded from subsequent analyses...
