Endoscopic Procedures I: Esophagogastroduodenoscopy

62
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:

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

46
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

73
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,...

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

46
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...

Area of Science:

  • Gastroenterology
  • Medical Imaging
  • Biomaterials

Background:

  • Gastrointestinal endoscopy faces challenges with air/CO2 insufflation, causing artifacts and obscuring lesions within folds.
  • Inadequate insufflation in folded regions like the stomach, intestine, and colon hinders lesion visualization.
  • Excessive insufflation can obscure bleeding lesions and other abnormalities, compromising diagnostic accuracy.

Purpose of the Study:

  • To review the application of transparent gels in gastrointestinal endoscopy.
  • To elucidate how specific viscosity gels address visualization challenges.
  • To present gels as a solution for enhanced endoscopic visualization without air/CO2.

Main Methods:

  • Review of recent literature on transparent gels in endoscopy.
  • Analysis of gel properties (viscosity) and their impact on visualization.
  • Evaluation of gel-based endoscopic techniques for lesion detection.

Main Results:

  • Transparent gels facilitate lesion observation without air/CO2 delivery.
  • Gels ensure optimal gastrointestinal tract expansion, improving visualization.
  • Specific viscosities of gels effectively mitigate artifacts and improve lesion assessment.

Conclusions:

  • Transparent gels represent a promising advancement in endoscopic visualization.
  • Gels offer a viable alternative to air/CO2 insufflation, enhancing diagnostic capabilities.
  • Further research into gel formulations can optimize endoscopic procedures.
