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...
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 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 Studies I: Bronchoscopy and Thoracoscopy01:30

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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 to...

Area of Science:

  • Medical Technology
  • Surgical Innovation
  • Human Factors Engineering

Background:

  • Ergonomic challenges in flexible endoscopy, including monitor positioning, are critical.
  • Head-mounted display (HMD) technology offers potential for ergonomic improvements independent of room setup.
  • This study assesses the feasibility and ergonomic advantages of immersive endoscopy with HMDs.

Purpose of the Study:

  • To evaluate the feasibility of immersive endoscopy using HMD technology.
  • To compare the ergonomic benefits of immersive endoscopy against standard and non-ergonomic settings.
  • To quantify improvements in procedure time, muscle effort, and mental workload.

Main Methods:

  • The Apple Vision Pro (AVP) video see-through HMD was utilized.
  • Participants performed an endoscopic marking task under three conditions: ergonomic, non-ergonomic, and immersive.
  • Key metrics included procedure time, muscle effort (electromyography), and mental workload (NASA-TLX).

Main Results:

  • Immersive and ergonomic settings significantly reduced procedure time and mental workload compared to the non-ergonomic setting.
  • Both immersive and ergonomic settings demonstrated lower muscle activation in key neck and shoulder muscles versus the non-ergonomic setting.
  • Immersive endoscopy showed further reductions in muscle activation in specific postural muscles compared to the ergonomic setting.

Conclusions:

  • Immersive endoscopy with AVP enhances performance and decreases muscle effort and mental workload compared to non-ergonomic setups.
  • The technology provides ergonomic advantages, reducing postural muscle activation even beyond traditional ergonomic configurations.
  • HMD-based immersive endoscopy presents a promising solution for improving endoscopist ergonomics and efficiency.
