Endoscopic Studies I: Bronchoscopy and Thoracoscopy

321
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...

Endoscopic Studies II: Thoracocentesis

787
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...

Summary
This summary is machine-generated.

Transoral endoscopic thyroidectomy vestibular approach (TOETVA) and gasless endoscopic thyroidectomy transaxillary approach (GETTA) are safe thyroid surgery options. GETTA offers faster operating times, while TOETVA provides more effective central lymph node dissection.

Area of Science:

  • Minimally Invasive Endoscopic Surgery
  • Head and Neck Surgery
  • Surgical Oncology

Background:

  • Endoscopic thyroidectomy approaches are gaining popularity for reduced scarring and improved cosmesis.
  • Comparing the transoral endoscopic thyroidectomy vestibular approach (TOETVA) and the gasless endoscopic thyroidectomy transaxillary approach (GETTA) is crucial for surgical decision-making.
  • Both TOETVA and GETTA aim to provide safe and effective thyroidectomy with minimal external scarring.

Purpose of the Study:

  • To compare the surgical safety and outcomes of TOETVA and GETTA.
  • To evaluate differences in operative time, complication rates, post-operative complaints, cosmetic satisfaction, and central lymph node dissection efficacy between the two approaches.

Main Methods:

  • Retrospective comparative study of 150 patients undergoing TOETVA and 150 patients undergoing GETTA.
  • Data collected on workspace creation time, operative time, complications, post-operative complaints, cosmetic satisfaction, and central neck lymph node yield.
  • Statistical analysis to compare outcomes between the TOETVA and GETTA groups.

Main Results:

  • No significant difference in post-operative complications between TOETVA and GETTA.
  • GETTA demonstrated significantly shorter workspace creation and operative times compared to TOETVA (P < 0.001).
  • TOETVA resulted in a higher number of central lymph nodes dissected (7.2 ± 4.6 vs. 3.9 ± 3.0, P < 0.001) but was associated with greater swallowing impairment at 1 month (2.6 ± 1.4 vs. 1.5 ± 1.2, P < 0.001).

Conclusions:

  • Both TOETVA and GETTA are safe and provide excellent cosmetic outcomes for selected patients.
  • GETTA offers a significant time-cost advantage in terms of operative efficiency.
  • TOETVA shows superior efficacy in central lymph node dissection, though potentially at the cost of temporary swallowing difficulties.
