This prospective follow-up study was designed to analyze the causes and outcome of upper gastrointestinal bleeding among patients presenting by hematemesis and/or melena to Emergency Endoscopy Unit, Ain Shams University Hospitals. One thousand patients presented by upper GIT bleeding were subjected to complete clinical evaluation, emergency upper gastrointestinal endoscopy and therapeutic inter...

Esophagogastric varices are considered to be the most common complication in patients with portal hypertension. Endoscopic ultrasonography not only visualizes the surface of the varices but also provides detailed information about their internal structure. The direction of blood flow can be determined and its velocity measured only via endoscopic color Doppler ultrasonography (ECDUS). This can ...

PURPOSE Adenocarcinomas of the distal esophagus and gastric cardia are two tumors that have many features in common. They have similar prognoses, treatment modalities, and patterns of dissemination. The etiology is different, with gastroesophageal reflux disease playing a major role for esophageal adenocarcinoma, in contrast to adenocarcinoma of the gastric cardia. In the present study, we inve...

CASE REPORT A 42-year-old female presented with long-standing symptoms suggestive of gastroesophageal reflux disease improved after proton pump inhibitor treatment. An upper endoscopy revealed an intrathoracic position of the stomach (type 4 hiatal hernia) with no mucosal abnormality. Barium swallow demonstrated gastric herniation with gastric volvulus without stenosis. A computed tomographic s...

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...

Sodium picosulfate/magnesium citrate (SPMC) is a widely used oral bowel cleansing agent considered to be relatively safe. However, partially dissolved or undissolved SPMC powder may cause severe injuries of the esophagus and stomach. We report a very rare case of acute gastric injury without esophageal damage caused by the ingestion of undissolved SPMC powder. A 69-year-old man experienced epig...

Nutrition in gastrointestinal (GI) cancer is an important part of treatment protocol. A detailed study published guidelines necessary to prevent pre-operative malnutrition and sustain peri-operative nutrition such patients. In this review, we discuss propose recommendations based on established suit the Indian population with different GI cancers (gastric, esophageal, pancreatic, colorectal hep...

Acute changes in blood glucose concentration have major effects on gastrointestinal motor function. Patients with diabetes mellitus have an increased prevalence of gastroesophageal reflux. Transient lower esophageal sphincter (LES) relaxation (TLESR) is the most common sphincter mechanism underlying reflux. The aim of this study was to investigate the effect of acute hyperglycemia on triggering...

HYPOTHESIS There is general agreement that a Heller myotomy should extend 6 to 7 cm above the gastroesophageal junction. Results of most previous studies have recommended that the myotomy extend 1 to 1.5 cm below the gastroesophageal junction. We speculated that the effectiveness of the operation could be improved if a longer, 3-cm myotomy was carried out below the gastroesophageal junction, as...
