Endoscopic Procedures I: Esophagogastroduodenoscopy

2.4K
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 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 III: Video Capsule Endoscopy

1.5K
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,...

Summary

Endoscopic submucosal dissection (ESD) allows complete removal of colorectal tumors. ESD with snaring offers a bridge between endoscopic mucosal resection (EMR) and full ESD, improving tumor removal reliability and ease.

Area of Science:

  • Gastroenterology
  • Endoscopic Surgery

Background:

  • Endoscopic submucosal dissection (ESD) enables en bloc resection of colorectal lesions.
  • ESD for colorectal tumors presents significant technical challenges.
  • Endoscopic mucosal resection (EMR) is suitable for early-stage tumors, but larger ones may need piecemeal resection.

Purpose of the Study:

  • To evaluate endoscopic submucosal dissection (ESD) with snaring as a technique for colorectal tumors.
  • To determine if ESD with snaring can bridge the gap between endoscopic mucosal resection (EMR) and full ESD.
  • To assess the reliability and ease of ESD with snaring for colorectal tumor resection.

Main Methods:

  • Review of techniques for colorectal tumor resection.
  • Proposal and evaluation of endoscopic submucosal dissection (ESD) with snaring.
  • Comparison of ESD with snaring to conventional EMR and ESD.

Main Results:

  • ESD with snaring is proposed as a method to improve upon EMR for larger colorectal tumors.
  • This technique aims to make colorectal ESD more manageable and reliable.
  • It serves as an intermediate step towards full ESD adoption.

Conclusions:

  • Endoscopic submucosal dissection (ESD) with snaring is a promising technique for colorectal tumors.
  • It offers a viable alternative for lesions that are too large for standard EMR but pose challenges for full ESD.
  • This approach facilitates a smoother transition to more advanced endoscopic resections.
