Mucosal Barrier of the Stomach01:25

Mucosal Barrier of the Stomach

2.1K
The gastric glands contain parietal cells that secrete hydrochloric acid (HCl) for digestion. The cells secrete HCl because it is highly corrosive and essential for breaking down food. To achieve this, they secrete hydrogen and chloride ions into the lumen of the gastric glands, which combine to form HCl.
Within parietal cells, carbonic acid is first formed through the reaction of water and carbon dioxide. The dissociation of carbonic acid releases bicarbonate and hydrogen ions. The bicarbonate...

Endoscopic Studies II: Thoracocentesis

1.3K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Endoscopic Procedures V: ERCP

2.9K
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.

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Conventional endoscopic mucosal resection (EMR) is standard but lacks evidence for submucosal injection efficacy.
  • Suboptimal submucosal injections can complicate EMR procedures, increasing risks.

Purpose of the Study:

  • To evaluate underwater endoscopic mucosal resection (UEMR) as an alternative to conventional EMR for colonic neoplasms.
  • To compare UEMR outcomes with EMR and endoscopic submucosal dissection (ESD).

Main Methods:

  • UEMR technique involves performing EMR underwater, eliminating the need for submucosal injections.
  • Outcomes including complete resection rates, safety, recurrence, and repeat procedures were compared.

Main Results:

  • UEMR achieved complete resection rates similar to conventional EMR.
  • UEMR demonstrated comparable safety to EMR, with lower recurrence and repeat procedure rates.
  • UEMR showed favorable outcomes compared to ESD regarding procedure time, resection, recurrence, and complications.

Conclusions:

  • UEMR is a viable alternative to conventional EMR for colonic neoplasms.
  • UEMR offers comparable or superior outcomes to EMR and ESD, with enhanced safety and reduced recurrence.
