Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

1.4K
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 Procedures I: Esophagogastroduodenoscopy

1.1K
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: Colonoscopy

727
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 Procedures V: ERCP

3.3K
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.

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...

Summary

The porcine spine effectively models human anatomy for practicing transforaminal percutaneous endoscopic lumbar procedures (TF-PELP). This study validates its use for surgical training and skill development.

Area of Science:

  • Spinal Surgery
  • Anatomical Modeling
  • Minimally Invasive Techniques

Background:

  • Transforaminal percutaneous endoscopic lumbar procedures (TF-PELP) require specialized training models.
  • Cadaveric models are crucial for developing and refining surgical skills.

Purpose of the Study:

  • To validate the porcine spine as a suitable anatomical model for learning and practicing TF-PELP.
  • To assess the anatomical relevance of the porcine spine compared to human anatomy.

Main Methods:

  • TF-PELP was performed on three porcine cadaver lumbar spine levels.
  • Anatomical features were compared between porcine and human spines.
  • Endoscopic procedure performance and documentation were detailed.

Main Results:

  • The porcine spine model demonstrated anatomical characteristics representative of the human spine.
  • Successful completion of transforaminal approaches was achieved.
  • The outside-in technique proved feasible and beneficial for practicing surgical maneuvers despite lower disc heights.

Conclusions:

  • The porcine spine serves as an effective and representative model for TF-PELP training.
  • The study identified procedural challenges and anatomical differences compared to the human spine.
