CONTEXT Gastroparesis is defined by delayed gastric emptying without mechanical obstruction of the gastroduodenal junction, which has been increasingly investigated. Nevertheless, knowledge on the relationships between etiology, symptoms and degree of delayed gastric emptying is limited. OBJECTIVES The demographic, clinical and etiological features of Brazilian patients with gastroparesis wer...

Whether mental stress is important in the pathogenesis of gastric mucosal disorders is not clearly established. This study investigated the relationship between sympathetic activation caused by the Stroop's colour word conflict test and gastric mucosal function, monitored by measuring the gastric mucosal electrical potential difference (PD). In 13 healthy volunteers and 12 duodenal ulcer patien...

The elderly population has experienced increased life expectancy as well as the increased incidence of gastric ulcers. The peels of fruits from Citrus aurantium L., popularly known in Brazil as orange bitter, are commonly used asatea form for the treatment of gastrointestinal tract disorders, such as ulcer and gastritis. We evaluated the healing effects of essential oil from the peels of Citrus...

Acid peptic diseases are common gastrointestinal disorders, which include gastroesophageal reflux disease, peptic ulcers, non-ulcer dyspepsia and stressrelated gastric mucosal injury. Drugs commonly used in the management of these disorders include antacids, H2 blockers, proton pump inhibitors and mucosal protective agents. In this chapter, pharmacology of these drugs will be discussed, followe...

Background: Not all patients with acid-related disorders receiving proton pump inhibitor (PP) treatment get adequate gastric pH control. The genetic variation of receptors, metabolic enzymes, and transporters are known to cause failures of therapies. We have conducted a study to evaluate the influence of gastric H+/K+-ATPase, CYP2C19, and ABCB1 polymorphisms on the pharmacokinetic and pharmacod...

Certain gastric disorders affect spatiotemporal parameters of the gastric slow wave. Whereas the electrogastrogram (EGG) evaluates electric potentials to determine primarily temporal parameters, fundamental physical limitations imposed by the volume conduction properties of the abdomen suggest the evaluation of gastric magnetic fields. We used a multichannel superconducting quantum interference...

Functional dyspepsia and gastroparesis represent the most common sensory-motor disorders of upper gastrointestinal tract. Scientific advances in last decade have shown that there is significant overlap between them. This review aims to address current knowledge about their pathophysiology, diagnosis treatment. a medical condition characterized by one or more following symptoms: early satiety, p...

Helicobacter pylori (H. pylori) which colonizes the stomach can cause a wide array of gastric disorders, including chronic gastritis, peptic ulcer, and gastric cancer. Recently, accumulating evidence has implicated H. pylori infection in extragastrointestinal diseases such as cardiovascular diseases, neurological disorders, and metabolic diseases. At the same time, many scholars have noted the ...

Disorders of small bowel function after gastric surgery are well recognized and occur even after vagotomy and drainage procedures (Logan, 1964). Various aetiological factors have been suggested. They include altered motility, inadequate mixing of food and digestive enzymes, diminished pancreatic secretion, and the effect of blind or stagnant loops. Watson, Watt, Paton, Glen, and Lewis (1966) su...

BACKGROUND A wireless motility capsule is a new method for ambulatory assessment of transit times and motility throughout the gastrointestinal tract. The objective of this study was to evaluate the ability of a wireless motility capsule to detect drug effects on gastric emptying time (GET) and gastric contractility. METHODS 15 healthy adults were administered in random order saline, erythromy...
