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:

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...

Area of Science:

  • Otolaryngology
  • Surgical Innovation
  • Auditory Neurosciences

Background:

  • Otosclerosis causes hearing loss due to stapes fixation.
  • Traditional stapedotomy techniques carry risks and limitations.
  • Endoscopic approaches offer potential for minimally invasive ear surgery.

Purpose of the Study:

  • To present a novel surgical technique for fully endoscopic transcanal stapedotomy.
  • To evaluate the preliminary outcomes and safety of this endoscopic approach.
  • To assess the efficacy in managing hearing loss from otosclerosis.

Main Methods:

  • Eight consecutive patients underwent fully endoscopic transcanal stapedotomy under local anesthesia.
  • A posterior tympanomeatal flap was elevated, stapes fixation addressed, and a microdrill used for footplate fenestration.
  • Platinum/fluoroplastic piston prostheses were inserted, and the chorda tympani nerve was preserved.

Main Results:

  • Postoperative audiograms at 6 months showed improved air- and bone-conduction thresholds.
  • The average air-bone gap was within 10 dB in most cases.
  • No intraoperative or postoperative complications were reported, with the chorda tympani nerve preserved.

Conclusions:

  • Fully endoscopic transcanal stapedotomy is a feasible and safe surgical technique.
  • This minimally invasive approach effectively addresses hearing loss in otosclerosis.
  • Further research with larger cohorts is warranted to confirm long-term efficacy.
