Endoscopic Procedures V: ERCP

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 Studies I: Bronchoscopy and Thoracoscopy

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:

Surgical technology
Medical imaging
Computer-assisted surgery

Background:

Laparoscopic surgery faces visualization challenges, particularly in accurately identifying target organs.
Augmented reality (AR) offers a solution by integrating 3D medical data (CT/MRI, ultrasound) with real-time surgical camera views.

Purpose of the Study:

To review current advancements in augmented reality visualization for surgical applications.
To explore the future directions of AR technology in laparoscopic surgery.

Main Methods:

Real-time fusion of 3D organ models with live laparoscopic video.
Tracking of the laparoscope and registration of the target organ for accurate image overlay.
Development of AR systems incorporating real-time image analysis for organ motion tracking.

Main Results:

AR enables geometrically correct image superimposition, improving surgeons' anatomical understanding.
Successful application of AR in general surgery and urology, including laparoscopic and robot-assisted procedures.
Current AR systems are limited by the dynamic tracking of organ motion and deformation.

Conclusions:

Augmented reality visualization represents a significant step forward in enhancing laparoscopic and endoscopic surgical precision.
Further technological development is needed to address limitations in dynamic organ tracking for improved surgical guidance.
