Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

1.2K
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 Studies I: Bronchoscopy and Thoracoscopy

888
Endoscopy is a non-surgical medical technique used to examine a person's internal organs and vessels. This lesson will focus on two types of endoscopic studies: bronchoscopy and thoracoscopy.
Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due...

Endoscopic Procedures I: Esophagogastroduodenoscopy

1.9K
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:

Area of Science:

  • Otolaryngology
  • Surgical Technology
  • Medical Imaging

Background:

  • Microscopes traditionally provided 3D vision in sinus surgery.
  • Two-dimensional (2D) endoscopes revolutionized visualization but lack stereoscopic depth perception.
  • Advancements in 3D endoscope technology offer potential for improved surgical visualization.

Purpose of the Study:

  • To clinically investigate and compare the efficacy of commercially available 3D endoscopes against conventional 2D HD endoscopes in functional endoscopic sinus surgery (FESS).
  • To evaluate surgeon perception of stereoscopic depth perception (SDP), image sharpness, brightness, and comfort during FESS procedures.

Main Methods:

  • A prospective, randomized, controlled clinical study involving 46 patients with polypoid chronic rhinosinusitis undergoing FESS.
  • Comparison of three endoscopic systems: 2D 0° high definition (HD), 3D 0° standard definition (SD), and 3D 0° HD.
  • Qualitative assessment by four surgeons on SDP, sharpness, brightness, and comfort.

Main Results:

  • 3D HD endoscopes demonstrated significantly superior stereoscopic depth perception (SDP) compared to 2D HD (p < 0.0001).
  • Surgeons rated the brightness of 3D HD significantly better than 3D SD (p = 0.038) and comfort in use higher than the control (p = 0.025).
  • No significant differences in image sharpness were observed among the tested endoscopes.

Conclusions:

  • 3D HD endoscopy represents a significant advancement in endoscopic sinus surgery, enhancing intraoperative visualization.
  • Improved SDP and brightness offered by 3D HD endoscopes contribute to better surgical field clarity and efficiency.
  • 3D HD endoscopy is an important and effective development for functional endoscopic sinus surgery.
