Postprandial hypotension occurs frequently, particularly in the elderly. The magnitude of the fall in blood pressure (BP) and rise in heart rate (HR) in response to enteral glucose are greater when gastric emptying (GE) or small intestinal infusion are more rapid. Meal ingestion is associated with an increase in splanchnic blood flow. In contrast, gastric distension may attenuate the postprandi...

abstract bowel obstruction is a known complication after bariatric surgery especially roux-en-y gastric bypass. the known etiologies include internal hernia, jejunojejunostomy stricture, ileus, intussusceptions, superior mesenteric artery syndrome, incarcerated port site hernia, and adhesions. blood clot is a rare cause of small intestinal obstruction after laparoscopic roux-en-y gastric bypass...

Objectives: The aim of this study was to investigate Endoscopic Ultrasonography with Color Doppler (ECDUS) findings of gastric varices and to determine the role of ECDUS in the diagnosis of gastric varices. Methods: Two hundred-fifteen patients with gastric varices found consecutively by routine upper endoscopy were evaluated with ECDUS. We monitored the color flow images of gastric varices, pa...

abstract background: gastric cancer is a life threatening disease. recent studies have shown that rosa damascene possesses noticeable biological effects on the human body. this study, investigates the anticancer effect of rosa damascena on gastric cancer cell line mkn45. methods: microscopic studies and mtt assay were used to examine morphological alteration, and cell survival of the cancer cel...

Measurement of gastric wall PCO2 (PgCO2) by tonometric method has emerged as an attractive option for estimating visceral perfusion during circulatory shock. However, gastric acid secretion obfuscates the tonometric measurement. We, therefore, investigated the option of measuring PCO2 in the esophagus to minimize these restraints. Hemorrhagic shock was induced in five Sprague-Dawley rats, and f...

Balloon-occluded retrograde transvenous obliteration (B-RTO) has been used successfully to treat gastric varices in adults. However, only a few case reports of B-RTO in children have been published. We describe a child who had gastric varices with extrahepatic portal venous obstruction (EHO). A 12-year-old boy presented to the pediatric clinic with anemia and tarry stools. He was referred to ou...

Previous studies have shown that treatment with ghrelin exhibits protective and therapeutic effects in the gut. Aim of our present investigation was to examine the influence of ghrelin administration on the healing of ethanol-induced gastric ulcers and determine the role of cyclooxygenase-1 and cyclooxygenase-2 in this effect. Our studies were performed on male Wistar rats. Gastric ulcers were ...
