Summary
A virtual coach effectively trains surgeons in functional endoscopic sinus surgery (FESS). This mixed-reality tool provides real-time data, improving novice performance and demonstrating high user satisfaction for enhanced surgical education.
Area of Science:
- Medical simulation
- Surgical education
- Virtual reality in medicine
Background:
- Functional endoscopic sinus surgery (FESS) training is challenging for novices.
- Current training methods require significant time and expense.
- A virtual coach may offer a more accessible training solution.
Purpose of the Study:
- To validate a virtual coach for step-by-step guidance in basic FESS.
- To assess the coach's effectiveness in a mixed-reality surgical environment.
Main Methods:
- Seventeen surgeons (10 novice, 7 expert) used a Neurorhinological Surgery (NRS) simulator with a virtual coach.
- The coach provided video, auditory, and visual cues during a maxillary antrostomy module.
- Objective data (border contacts, completion time) and user feedback were collected.
Main Results:
- The NRS simulator showed face and construct validity, differentiating novice and expert surgeons (p < 0.01).
- Novices contacted more anatomical borders and had longer operative times.
- All users reported high satisfaction with the virtual coach's usefulness.
Conclusions:
- The virtual coach is a valuable tool for FESS education.
- It offers objective, real-time data in a mixed-reality setting.
- This technology can enhance surgical training and skill acquisition.

626
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,...

468
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...

758
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:

2.4K
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.

465
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...

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:
