Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

1.5K
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

1.2K
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

752
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

3.5K
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

636
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...

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Endoscopic Surgery

Background:

  • Computed tomography (CT) and magnetic resonance imaging (MRI) are standard for neurosurgical navigation.
  • Single imaging modalities have limitations in visualizing delicate intracranial structures.
  • Multimodality imaging has shown promise in glioma removal but its utility in endoscopic transsphenoidal surgery is unexplored.

Purpose of the Study:

  • To evaluate the clinical utility of multimodality imaging for navigation in endoscopic transsphenoidal surgeries.
  • To assess the precision of multimodality imaging in visualizing sphenoidal sinus anatomy and tumors compared to single modalities.

Main Methods:

  • 134 patients undergoing endoscopic transsphenoidal surgery with multimodality image navigation were analyzed.
  • CT and MRI data were fused and processed for optimal visualization of the sphenoidal sinus and tumor anatomy.

Main Results:

  • Multimodality image navigation provided a more precise display of sphenoidal sinus anatomical structures than CT or MRI alone.
  • Fused images enabled accurate visualization of sphenoidal sinus structures, lesions, and tumors.

Conclusions:

  • Multimodality image navigation offers optimized guidance for endoscopic transsphenoidal surgeries.
  • Precise visualization enhances surgical safety, especially with anatomical variations, and may reduce tumor recurrence rates.
