Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

1.3K
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

1.0K
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

681
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

3.1K
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.

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

Varus malunion after subtalar arthrodesis can lead to poor outcomes. This technical note describes an endoscopic revision technique to correct this deformity, potentially reducing complications.

Area of Science:

  • Orthopedic surgery
  • Foot and ankle reconstruction
  • Minimally invasive surgical techniques

Background:

  • Varus malunion is a severe hindfoot deformity after subtalar arthrodesis.
  • Malunion exceeding 10° with lateral column overload predicts poor clinical outcomes.
  • Open revision subtalar arthrodesis carries significant risks of soft tissue complications and nonunion.

Purpose of the Study:

  • To detail the technical aspects of endoscopic revision subtalar arthrodesis.
  • To present a minimally invasive approach for correcting varus malunion.
  • To explore the potential benefits of this technique in reducing surgical complications.

Main Methods:

  • Description of the technical steps for endoscopic revision subtalar arthrodesis.

  • Focus on the minimally invasive approach to correct varus malalignment.
  • Emphasis on techniques to mitigate soft tissue and nonunion risks.

    • Main Results:

    • The technical note outlines a method for endoscopic correction of varus malunion.
    • The described technique aims to minimize soft tissue disruption.
    • Potential for reduced nonunion rates compared to open procedures is implied.

    Conclusions:

    • Endoscopic revision subtalar arthrodesis offers a minimally invasive option for varus malunion.
    • This technique may decrease the incidence of soft tissue complications and nonunion.
    • Further studies are warranted to validate clinical outcomes and long-term efficacy.
