Endoscopic Studies I: Bronchoscopy and Thoracoscopy

Endoscopic Studies I: Bronchoscopy and Thoracoscopy

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...

Green Algae

Green Algae

Green algae, also referred to as chlorophytes, are different from red algae in having the chloroplasts containing chlorophylls a and b, which give them their distinct green hue. However, they lack phycobiliproteins, preventing them from developing the red or blue-green pigmentation seen in red algae. In terms of photosynthetic pigment composition, green algae closely resemble plants and share a close evolutionary relationship with them. Taxonomically Green algae belong to Phylum Chlorophyta in...

Infrared (IR) Spectroscopy: Overview

Infrared (IR) Spectroscopy: Overview

When electromagnetic radiation passes through a material, atoms or molecules transition from a lower to a higher energy state by absorbing radiation corresponding to the energy difference between the two states. The absorption of infrared (IR) radiation causes transitions between vibrational energy levels in a molecule. Therefore, IR spectroscopy is a useful analytical tool for determining the molecular structure of molecules.
Different compounds display unique properties due to their...

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

Attenuated Total Reflectance (ATR) Infrared Spectroscopy: Overview

Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
The ATR process begins by directing a beam...

Base Excision Repair

Base Excision Repair

One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Lewis Acids and Bases

Lewis Acids and Bases

In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Area of Science:

Thoracic Surgery
Surgical Oncology
Minimally Invasive Surgery

Background:

Increasing reports of indocyanine green (ICG) infrared thoracoscopy for segmentectomy.
ICG allows clear intersegmental line identification, unaffected by air drift, beneficial for complex procedures.
Auto staplers show potential in reducing air leakage compared to electrocautery.

Purpose of the Study:

To evaluate the feasibility and utility of thoracoscopic stapler-based segmentectomy using ICG-infrared thoracoscopy.
To assess the safety and efficacy of this combined surgical approach.

Main Methods:

Retrospective evaluation of 92 patients undergoing thoracoscopic segmentectomy with ICG-infrared thoracoscopy and staplers.
Data collected on patient demographics, surgical indications, procedure details, and postoperative outcomes.

Main Results:

The procedure was successfully completed in all patients, with only 2 requiring minor thoracotomy.
Intersegmental borders were well visualized with ICG.
Low rates of postoperative complications (12.0%) and air leakage (2.2%) were observed, with no mortality.
Median chest tube duration was 3 days and median hospital stay was 5 days.

Conclusions:

Thoracoscopic stapler-based segmentectomy using ICG-infrared thoracoscopy is a feasible and useful surgical technique.
The combination of ICG visualization and stapler use offers a safe and effective approach for lung segmentectomy.
