Gastroesophageal Reflux Disease01:25

Gastroesophageal Reflux Disease

38
Gastroesophageal reflux disease (GERD) is the backward flow of stomach contents (acid, pepsin, or bile) into the esophagus, causing mucosal inflammation known as esophagitis. It results from failure of antireflux mechanisms, mainly the lower esophageal sphincter (LES), influenced by mechanical and physiological factors.Etiology and Risk FactorsGERD develops when LES function is weakened or when intra-abdominal pressure increases. Risk factors include aging, obesity, and sliding hiatal hernia,...

Pyloric Obstruction01:11

Pyloric Obstruction

34
Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology

2.0K
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

Gastroesophageal Reflux Disease II: Clinical Features and Management

1.1K
Gastroesophageal reflux disease, or GERD, is a persistent medical condition that affects many individuals worldwide. Its clinical manifestations can vary greatly, making diagnosis and management challenging for healthcare professionals. The following is a comprehensive overview of the clinical manifestations, assessment, and management strategies for GERD.
Clinical Manifestations
GERD presents itself in a multitude of ways, with symptoms varying from person to person. The hallmark symptoms are...

Gastric Emptying01:16

Gastric Emptying

5.4K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

7.1K
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.
