background: recent researches have led to find strategies to prevent relapse and to improve survival for gastric cancer patients, including preoperative neo-adjuvant approaches. however, the efficacy of some neo-adjuvant regimens including 5-fluorouracil, cisplatin, and docetaxel have been less investigated. the present study evaluated the outcome and mid-term survival of patients with gastric ...

mast cells are related to certain gastrointestinal complaints. mast cell density has not been studied in cardio-esophageal region to the best of our knowledge. in this study we wanted to obtain an estimate of mast cell density in this region and compare it with mast cell density in antrum. from april 2007 till march 2010, we chose children (<14 years old) who underwent upper endoscopy and from ...

background: one million people are diagnosed with gastric cancer (gc) annually and the prognosis for patients with advanced gc or gastroesophageal junction (gej) cancer is usually poor with a median survival time of 8 to 10 months. recent reports have identified that anti her2 target therapy improved the median survival rate in patients with her2 positive gc; but a wide range of her2 overexpres...

The aim of this study was to combine the anatomy and physiology of the human gastroesophageal junction (the junction between the esophagus and the stomach) into a unified computer model. A three-dimensional (3D) computer model of the gastroesophageal junction was created using cross-sectional images from a human cadaver. The governing equations of finite deformation elasticity were incorporated...

A laparoscopic wedge resection for a submucosal tumor, which is close to the gastroesophageal junction, is technically challenging. This can be a dilemma to both patients and surgeons when the tumor margin involves the gastroesophageal junction because a wedge resection in this situation might result in a deformity of the gastroesophageal junction or an injury to the lower esophageal sphincter,...

Chemotherapy for advanced gastric and gastroesophageal junction carcinomas remains suboptimal. Both irinotecan (Camptosar) and cisplatin (Platinol) are active against this group of malignancies. This article focuses on the results of an ongoing phase II trial with this combination in patients with advanced gastric or gastroesophageal junction carcinoma. Data from this trial suggest that the com...

BACKGROUND/AIMS Detailed characterization of the ultrastructural morphology of intercellular space in gastroesophageal reflux disease has not been fully studied. We aimed to investigate whether subtle alteration in intercellular space structure and tight junction proteins might differ among patients with gastroesophageal reflux disease. METHODS Esophageal biopsies at 5 cm above the gastroesop...

BACKGROUND/AIMS The gastroesophageal junction is an important barrier against gastroesophageal ref lux. Endoscopic grading of gastroesophageal f lap valve is simple, reproducible, and may predict reflux activity. We investigated the correlation between gastroesophageal flap valve grade and the gastroesophageal junction's structural properties using abdominal computed tomography. METHODS A tot...

At the gastroesophageal junction, most vertebrates possess a functional lower esophageal sphincter (LES) which may serve to regulate the passage of liquids and food into the stomach and prevent the reflux of gastric contents into the esophagus. Snakes seemingly lack an LES and consume meals large enough to extend anteriorly from the stomach into the esophagus thereby providing the opportunity f...
