Endoscopic Procedures III: Video Capsule Endoscopy01:28

Endoscopic Procedures III: Video Capsule Endoscopy

204
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 II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

354
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

237
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...

Urologic Endoscopic Procedure: Cystoscopic Examination

89
Meaning of Cystoscopic Examination:Cystoscopy is an essential diagnostic tool in urology that is used to assess the structure and function of the genitourinary system. It provides a direct view of the urethra, bladder, and, in some cases, the ureteral openings. This procedure helps detect structural abnormalities, infections, cancers, and blockages in the urinary tract. There are two types of cystoscopy:Flexible cystoscopy is commonly performed in outpatient settings due to its less invasive...

Endoscopic Procedures I: Esophagogastroduodenoscopy01:29

Endoscopic Procedures I: Esophagogastroduodenoscopy

208
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

136
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:

Area of Science:

  • Neurosurgery
  • Surgical Technology
  • Medical Education

Background:

  • Digital 3D exoscopes are emerging as an alternative to traditional surgical microscopes in microneurosurgery.
  • Assessing the learning curve and skill development associated with exoscope use is crucial for adoption.

Purpose of the Study:

  • To design and evaluate a laboratory training program for transitioning neurosurgeons from microscope to exoscope use.
  • To measure the impact of a one-year active training on microsurgical skills using a standardized exoscope task.

Main Methods:

  • Two neurosurgeons with no prior exoscope experience underwent a 12-month training program.
  • Standardized chicken wing artery dissection tasks were performed and video-recorded at multiple time points.
  • Dissection time and manual skill metrics were analyzed by independent evaluators.

Main Results:

  • Dissection time significantly decreased from a mean of 34 minutes to 26 minutes over the training period.
  • Participants demonstrated improved efficiency in exoscope utilization and instrument handling.
  • Correlation found between reduced dissection time and enhanced workflow metrics like focus control and instrument versatility.

Conclusions:

  • Continuous, dedicated training is effective for developing microsurgical skills when adopting exoscopes.
  • Exoscope proficiency increases with practice, leading to more efficient micromotor movements and versatile instrument use.
