Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

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:

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

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 Procedures II: Colonoscopy

Endoscopic Procedures II: Colonoscopy

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:

Summary

This summary is machine-generated.

Dual-channel endoscopic mucosal resection (EMR) simplifies colon polypectomy for large lesions. This technique may also shorten the learning curve for colonoscopy EMR, offering a promising approach for gastrointestinal procedures.

Area of Science:

Gastroenterology
Endoscopic Surgery

Background:

Endoscopic mucosal resection (EMR) is standard for large nonpedunculated colon polyps (>20 mm).
Single-channel EMR presents a learning curve for endoscopists.

Purpose of the Study:

To describe the technique of dual-channel EMR (DC-EMR) for colon polypectomy.
To outline potential complications, surveillance, and future directions for DC-EMR.

Main Methods:

Utilizes a dual-channel endoscope for improved submucosal injection, snare resection, and defect closure.
Details procedural steps and techniques for DC-EMR.

Main Results:

DC-EMR facilitates complex polypectomy steps.
Early literature suggests DC-EMR may reduce the learning curve compared to single-channel EMR.

Conclusions:

DC-EMR is an advanced endoscopic technique for large colon polyps.
This method shows potential for improved procedural efficiency and reduced training time.
