Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

7.1K
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 III: Video Capsule Endoscopy

1.4K
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 I: Esophagogastroduodenoscopy

2.3K
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 Studies I: Bronchoscopy and Thoracoscopy

1.1K
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 IV: Sigmoidoscopy and Laproscopy

1.2K
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:

Area of Science:

  • Ophthalmology
  • Neurosurgery
  • Medical Imaging

Background:

  • Orbital surgery is challenging due to confined anatomy and delicate structures.
  • Minimally invasive approaches are needed for conditions like optic neuropathies.
  • Current image-guided navigation faces limitations in endoscopic visualization.

Purpose of the Study:

  • To evaluate the impact of endoscopic video augmentation on image-guided navigation in orbital surgery.
  • To assess the system's effectiveness in improving target identification and procedure efficiency.
  • To explore potential benefits for minimally invasive transorbital interventions.

Main Methods:

  • 16 surgeons performed target identification tasks in skull phantoms.
  • Tasks involved distinguishing correct targets using augmented video and imaging.
  • Orbital interventions were conducted with and without video augmentation in a randomized order.

Main Results:

  • Target identification accuracy was 95.3% with augmentation versus 85.9% without.
  • Statistically significant improvements were observed in procedure time (p=0.041).
  • Intraoperator mean procedure time also showed significant improvement (p=0.014).

Conclusions:

  • Endoscopic video augmentation enhances orientation and trajectory information during image-guided procedures.
  • The technology offers potential to reduce complication risks in transorbital interventions.
  • Augmentation can improve surgeon confidence and comfort during complex orbital surgeries.
