Relation of atrophic gastritis with Helicobacter pylori-CagA(+) and interleukin-1 gene polymorphisms.

AIM: To determine the association of Helicobacter pylori (H pylori) CagA(+) infection and pro-inflammatory polymorphisms of the genes interleukin (IL)-1RN and IL-1B with the risk of gastric atrophy and peptic ulcers in a dyspeptic population in Costa Rica, a country with high incidence and mortality of gastric cancer. METHODS: Seven biopsy specimens, a fasting blood sample and a questionnaire concerning nutritional and sociodemographic factors were obtained from 501 consecutive patients who had undergone endoscopy for dyspeptic symptoms. A histopathological diagnosis was made. Pepsinogen conc

Gastric mucosa-associated lymphoid tissue lymphoma: radiographic findings in six patients.

PURPOSE: To determine the radiographic findings of low-grade gastric mucosa-associated lymphoid tissue (MALT) lymphoma on double-contrast upper gastrointestinal studies. MATERIALS AND METHODS: Pathology records, double-contrast upper gastrointestinal studies, and medical records of six patients with gastric MALT lymphoma were retrospectively reviewed. RESULTS: The most common clinical findings at presentation included epigastric pain (n = 6), dyspepsia (n = 4), and nausea and vomiting (n = 4). Double-contrast studies revealed rounded, often confluent nodules of varying size in four patients

Protocol for expanded indications of endoscopic submucosal dissection for early gastric cancer in China: a multicenter, ambispective, observational, open-cohort study.

BACKGROUND: The main treatment methods for early gastric cancer (EGC) include endoscopic submucosal dissection (ESD) and radical gastrectomy. However, appropriate treatment for patients who exceed the absolute indications for ESD remains unestablished. In China, evidence-based medicine for the expanding indications of ESD and accurate diagnostic staging for EGC patients are lacking. Thus, clinical studies involving Chinese patients with EGC are necessary to select appropriate treatment options and promote China's expanded indications for ESD and diagnostic staging scheme. METHODS: This is a m

Clinical and Immunologic Features of Ultra-Short Celiac Disease.

BACKGROUND & AIMS: The clinical effects of gluten-sensitive enteropathy with villous atrophy limited to the duodenal bulb (D1) have not been delineated in adults with celiac disease. We investigated the sensitivity of D1 biopsy analysis in the detection of celiac disease, the number and sites of biopsies required to detect ultra-short celiac disease (USCD, villous atrophy limited to D1), and the clinical phenotype of USCD. METHODS: We performed a prospective study of 1378 patients (mean age, 50.3 y; 62% female) who underwent endoscopy at a tertiary medical center in the United Kingdom from 20

Radiation microsphere-induced GI ulcers after selective internal radiation therapy for hepatic tumors: an underrecognized clinical entity.

BACKGROUND: Intra-arterial infusion of yttrium-90 (Y-90) microspheres is locoregional radiation therapy for unresectable hepatic neoplasms. Literature on GI complications of this novel therapy is sparse. OBJECTIVES: Clinically and pictorially characterize selective internal radiation therapy (SIRT)-induced GI injury and review the published literature. DESIGN: Retrospective chart analysis. SETTING: Single-center tertiary referral community hospital. PATIENTS: One hundred three patients treated with SIRT for hepatic neoplasms between 2006 and 2008. INTERVENTIONS: SIRT for unresectable hepa

The innovative potential of Lactobacillus rhamnosus LR06, Lactobacillus pentosus LPS01, Lactobacillus plantarum LP01, and Lactobacillus delbrueckii Subsp. delbrueckii LDD01 to restore the "gastric barrier effect" in patients chronically treated with PPI: a pilot study.

BACKGROUND: Gastroesophageal reflux disease is a very widespread condition. In Europe, it is estimated that about 175 million people suffer from this disease and have to chronically take drugs to increase gastric pH. The proton pump inhibitors (PPIs) such as omeprazole, lansoprazole, and esomeprazole are the most widely used drug typology in this regard. However, the inhibition of normal gastric acid secretion has important side effects, the most important being bacterial overgrowth in the stomach and duodenum with a concentration of >10⁵ viable cells/mL. As a major consequence of this, many h

Spontaneous pneumomediastinum: an extensive workup is not required.

BACKGROUND: Spontaneous pneumomediastinum is a rare entity usually caused by alveolar rupture and air tracking along the tracheobronchial tree. Despite its benign nature, an extensive workup is often undertaken to exclude hollow viscus perforation. We sought to review our experience with this condition and examine the optimal management strategy. STUDY DESIGN: We conducted a retrospective review of all radiographic pneumomediastinum cases at a tertiary hospital between 2006 and 2011. The main outcomes measures included length of hospital stay, mortality, and need for investigative procedures.

Esophageal hematoma after atrial fibrillation ablation: incidence, clinical features, and sequelae of esophageal injury of a different sort.

BACKGROUND: Esophageal hematoma recently has been reported as a form of esophageal injury after atrial fibrillation (AF) ablation, attributed to the use of transesophageal echocardiography (TEE). We sought to determine the incidence, clinical features, and sequelae of this form of esophageal injury. METHODS AND RESULTS: This was a prospective series of 1110 AF ablation procedures performed under general anesthesia (GA) over 9 years. TEE was inserted after induction of GA to exclude left atrial appendage thrombus, define cardiac function, and guide transseptal puncture. The procedural incidenc

An analysis of persistent symptoms in acid-suppressed patients undergoing impedance-pH monitoring.

BACKGROUND & AIMS: Despite proton-pump inhibitors (PPIs), patients may have persistent symptoms of gastroesophageal reflux disease (GERD). We aimed to identify symptom types and frequency experienced by patients on PPI therapy, and to identify the type of reflux, if any, associated with these symptoms. METHODS: A retrospective review was performed of 200 patients on PPI with GERD symptoms during ambulatory impedance-pH testing. The symptom index (SI) was determined for each symptom, and an SI of 50% or more was considered positive. Patients were divided into 2 groups: those with exclusively n

Helicobacter pylori cagA and iceA genotypes status and risk of peptic ulcer in Saudi patients.

OBJECTIVE: To determine the prevalence of cagA+ and iceA genotypes among Helicobacter pylori (H. pylori) isolates from a group of Saudi patients with gastric complaints, and to find out any significant correlation between these strains and severe gastric clinical outcomes such as peptic ulcer and gastric cancer in Saudi population. METHODS: A total of 1104 gastric biopsies from 368 patients who presented with symptoms suggestive of chronic gastritis, peptic ulcer disease, or gastric carcinoma were taken from the main hospitals in the Western region of Saudi Arabia from July 2004 to July 2005.

Long-term results of anti-Helicobacter pylori therapy in early-stage gastric high-grade transformed MALT lymphoma.

BACKGROUND: Several independent clinical studies have reported that Helicobacter pylori eradication therapy could achieve complete remission in some patients with H. pylori-positive early-stage gastric mucosa-associated lymphoid tissue (MALT) lymphoma. METHODS: To compare the long-term results of anti-H. pylori therapy in early-stage, gastric low-grade and high-grade transformed MALT lymphoma, two multicenter prospective studies of anti-H. pylori therapy for early-stage gastric lymphoma conducted in Taiwan, one for low-grade MALT lymphoma, with 34 patients enrolled from March 1996 through Apr

[Establishment and validation of a predictive nomogram model for advanced gastric cancer with perineural invasion].

Objective: Peripheral nerve invasion (PNI) is associated with local recurrence and poor prognosis in patients with advanced gastric cancer. A risk-assessment model based on preoperative indicators for predicting PNI of gastric cancer may help to formulate a more reasonable and accurate individualized diagnosis and treatment plan. Methods: Inclusion criteria: (1) electronic gastroscopy and enhanced CT examination of the upper abdomen were performed before surgery; (2) radical gastric cancer surgery (D2 lymph node dissection, R0 resection) was performed; (3) no distant metastasis was confirmed b…

Renal metastasis of gastric cancer caused acute kidney injury which resulted with hemodialysis: case report and literature review.

Gastric cancer ranks fourth among the most commonly diagnosed cancers, with over a million new cases diagnosed worldwide each year. Acute and chronic kidney damage are common in patients with malignant diseases and are associated with increased risk of complications and mortality. Rarely, acute renal insufficiency may result from bilateral infiltration of renal parenchyma by tumor cells from another organ. We present a case of a patient with clinical suspected gastric cancer and metastases to the kidneys leading to acute renal failure requiring hemodialysis. Despite gastric biopsies, no tumor

Phenotypic heterogeneity of hereditary diffuse gastric cancer: report of a family with early-onset disease.

BACKGROUND AND AIMS: The time course for the development of clinically significant hereditary diffuse gastric cancer (HDGC) is unpredictable. Little is known about the progression from preclinical, indolent lesions to widely invasive, aggressive phenotypes. Gastroendoscopy often fails to detect early lesions, and risk-reducing/prophylactic total gastrectomy (PTG) is the only curative approach. We present an HDGC family with early-onset disease in which clinical and histologic findings provided insight into the understanding of different HDGC phenotypes. METHODS: The proband was diagnosed at a

Time-dependent morphologic change in depressed-type early gastric cancer.

BACKGROUND: Depressed-type early gastric cancer (EGC) is known to repeat improvement and exacerbation of ulceration during its natural course, forming a "malignant cycle." However, it is difficult to observe the malignant cycle of EGC in clinical practice, and little is known about the clinicopathologic factors associated with this cycle. This study aimed to evaluate the malignant cycle of EGC and to determine the clinicopathologic factors associated with the time-dependent morphologic change of EGC. METHODS: The medical records of EGC patients treated at the Seoul National University Hospita

Factors That Affect Stent-Related Complications in Patients with Malignant Obstruction of the Esophagus or Gastric Cardia.

BACKGROUND/AIMS: Self-expandable metallic stent (SEMS) placement is effective for dysphagia that results from malignant obstruction of the esophagus or gastric cardia; however, stent-related complications may be life-threatening. Thus, the goal of this study was to identify risk factors associated with complications following esophageal stenting. METHODS: Of the 71 patients who underwent SEMS placement for dysphagia as a result of malignant stricture of the esophagus or gastric cardia, 53 patients with squamous cell carcinoma or adenocarcinoma, without previous SEMS placement, without a fistu
