Endoscopic Studies II: Thoracocentesis01:26

Endoscopic Studies II: Thoracocentesis

323
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 Studies I: Bronchoscopy and Thoracoscopy

231
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:

  • Thoracic Surgery
  • Surgical Innovation
  • Minimally Invasive Procedures

Background:

  • Thoracoscopic anatomical individual basilar segmentectomy presents significant challenges due to deep hilar structures and anatomical variations.
  • This study analyzes the experience and progress in performing these complex procedures at a university hospital.

Purpose of the Study:

  • To evaluate the learning curve and progression of thoracoscopic anatomical individual basilar segmentectomy.
  • To assess the impact of experience on surgical outcomes and efficiency.

Main Methods:

  • Retrospective analysis of 127 patients undergoing anatomical basilar segmentectomy between 2004 and 2021.
  • Division of the study period into an introductory (2004-2012) and a maturity (2013-2021) phase of video-assisted thoracoscopic surgery (VATS) segmentectomy.
  • Evaluation of the surgeon's learning curve using operative time and cumulative sum analysis during the maturity period.

Main Results:

  • The maturity period (2013-2021) saw higher patient age and comorbidity index but shorter postoperative hospitalization and operative times compared to the introductory period (2004-2012).
  • Increased use of uniport procedures was observed in the later period.
  • The learning curve analysis indicated that the inflection point for thoracoscopic basilar segmentectomy was reached after 42 cases.

Conclusions:

  • A single institution demonstrated significant progress in performing difficult thoracoscopic segmentectomies.
  • The identified learning curve provides valuable insights for other institutions considering this advanced surgical technique.
