The actions of cholecystokinin (CCK) on gastrointestinal functions occur mainly via paracrine effects on peripheral sensory vagal fibers, which engage vago-vagal brain stem circuits to convey effector responses back to the gastrointestinal tract. Recent evidence suggests, however, that CCK also affects brain stem structures directly. Many electrophysiological studies, including our own, have sh...

Complete esophageal stenosis secondary to peptic stricture in the upper esophagus is rare. It is, however a serious medical problem that may require otolaryngologic intervention because of life-threatening dysphagia and weight loss. We report the case of an elderly patient who presented with an upper esophageal stricture, without the typical symptoms of gastroesophageal reflux disease, that pro...

Our hypothesis was that rumination syndrome is associated with gastric sensory and motor dysfunction. We studied gastric and somatic sensitivity, reflex relaxation of the lower esophageal sphincter (LES), and gastric compliance and accommodation postprandially and postglucagon. A barostatically controlled gastric bag and esophageal manometry were used to compare gastric sensorimotor functions a...

introduction: the objective of the present study is to investigate the relationship between the familial history of digestive system cancers and development of gastric cancer. methods: in this case-control study conducted in 2012, 84 patients with a definite diagnosis of gastric cancer, diagnosed using endoscopy and pathological study of biopsies, were compared with 84 people with the same age ...

BACKGROUND A Stanford University study reported that in asymptomatic GERD patients who were being treated with a proton pump inhibitor (PPI), 50% had pathologic esophageal acid exposure. AIM We considered the possibility that the high prevalence of pathologic esophageal reflux might simply have resulted from calculating acidity as time pH < 4. METHODS We calculated integrated acidity and ti...

TOPIC: Disorders of the Mediastinum TYPE: Fellow Case Reports INTRODUCTION: Tracheo-esophageal fistula is a rare but known acquired complication in patients with esophageal malignancy. A broncho-gastric an even rarer that can occur who undergo esophagectomy esophago-gastric anastomosis thoracic cavity (1). It important to recognize it early as lead serious complications like recurrent pneumonia...

Bleeding from gastric varices is generally more severe than bleeding from esophageal varices, although it occurs less frequently. Recently, new endoscopic treatment options and interventional radiological procedures have broadened the therapeutic armamentarium for gastric varices. This review provides an overview of the classification and pathophysiology of gastric varices, an introduction to c...

Lipolytic activity was studied in esophageal and gastric aspirates obtained with a nasogastric tube from 14 healthy adult subjects. Samples were collected from esophagus, first at 30-35 cm and then at 40-45 cm from the nose, as the subject, after drinking 15-30 ml of a cream-milk mixture, swallowed small amounts of water. The samples from stomach were taken last and usually contained a small am...

To systematically and quantitatively review the relation of abdominal obesity, as measured by waist circumference (WC) and waist to hip ratio (WHR), to total gastroesophageal cancer, gastric cancer (GC), and esophageal cancer. PubMed and Web of Science databases were searched for studies assessing the association between abdominal obesity and gastroesophageal cancer (GC and/or esophageal cancer...

Most adenomas of the esophagus are mucin-producing lesions in the setting of Barrett esophagus, or originate in Barrett’s metaplastic epithelium, or are composed of cells with gastric epithelial features including parietal cells. Benign ductal or glandular neoplasms not associated with Barrett esophagus are very rare. There have been several reports of esophageal adenoma developing in the submu...
