Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

191
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: ERCP01:26

Endoscopic Procedures V: ERCP

399
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

133
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 Laproscopy

119
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 III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

189
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,...

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Electrosurgery

Background:

  • Electrosurgical units (ESUs) are essential tools in endoscopy.
  • Understanding ESU modes and settings is vital for patient safety and successful therapeutic outcomes.

Purpose of the Study:

  • To review optimal electrosurgical unit (ESU) settings for common and advanced endoscopic interventions.
  • To provide guidance on ESU waveform characteristics, duty cycle, and crest factor for effective tissue cutting and coagulation.
  • To address special considerations, such as managing patients with pacemakers during endoscopic procedures.

Main Methods:

  • Literature review of electrosurgical unit (ESU) applications in endoscopy.
  • Analysis of ESU waveforms, duty cycles, and crest factors relevant to endoscopic procedures.
  • Compilation of recommended settings for specific interventions like hemostasis, polypectomy, and sphincterotomy.

Main Results:

  • Specific ESU modes like Endocut I and Endocut Q are recommended for sphincterotomy and polypectomy, respectively.
  • Forced Coag mode (Effect 2, 60 W) is effective for controlling bleeding after sphincterotomy and for pre-coagulation of polyp stalks.
  • Optimizing duty cycle and crest factor is key for achieving desired cutting and coagulation effects.

Conclusions:

  • Appropriate knowledge and application of electrosurgical unit (ESU) settings significantly improve therapeutic results in endoscopy.
  • Adherence to recommended ESU parameters enhances procedural safety and patient outcomes.
  • This review offers practical guidance for endoscopists utilizing electrosurgery.
