Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

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 II: Colonoscopy01:25

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:
Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy01:26

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...
Endoscopic Procedures V: ERCP01:26

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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

Area of Science:

  • Gastroenterology
  • Medical Devices
  • Surgical Technology

Background:

  • Electrosurgery generators are vital in therapeutic endoscopy.
  • They produce high-frequency alternating current for cutting and coagulation.
  • This dual function makes them ideal for gastrointestinal procedures.

Purpose of the Study:

  • To connect fundamental electrosurgical principles with common endoscopic procedures.
  • To offer practical usage suggestions based on principles and clinical data.
  • To bridge the gap between electrosurgery knowledge and clinical application.

Main Methods:

  • Relating electrosurgical principles to procedures like snare polypectomy, hot biopsy, sphincterotomy, bipolar hemostasis, and argon plasma coagulation.
  • Reviewing available clinical data.
  • Synthesizing information for practical guidance.

Main Results:

  • Electrosurgery's cutting and coagulation capabilities are ideal for gastrointestinal endoscopy.
  • Understanding principles enhances safe and effective use of devices.
  • Specific procedures discussed include snare polypectomy, hot biopsy, sphincterotomy, bipolar hemostasis, and APC.

Conclusions:

  • Electrosurgery generators are indispensable tools in therapeutic endoscopy.
  • Linking basic principles to clinical practice improves safety and efficacy.
  • Practical guidance derived from principles and data supports optimal device utilization.
