Overview of Microscopy Techniques

Overview of Microscopy Techniques

The early pioneers of microscopy opened a window into the invisible world of microorganisms. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes that leveraged nonvisible light, such as fluorescence microscopy that uses an ultraviolet light source and electron microscopy that uses short-wavelength electron beams. These advances significantly improved magnification, image resolution, and contrast. By comparison, the...

Area of Science:

Gastroenterology
Endoscopic Surgery

Background:

Endoscopic removal of large foreign bodies, coagulated blood, or necrotic debris can be difficult due to limitations of current endoscopic instruments.
There is a need for innovative devices to improve the efficiency and safety of these procedures.

Purpose of the Study:

To evaluate the efficacy and safety of the over-the-scope grasper (OTSG) for endoscopic removal of challenging materials.

Main Methods:

The OTSG, a novel grasping tool attachable to standard gastroscopes, was used in five patients.
Indications included necrosectomy, bolus impaction, and removal of blood clots.
Procedures involved necrosectomy through lumen-apposing metal stents and removal of esophageal obstructions.

Main Results:

The OTSG was technically successful in all five patients.
Procedures included endoscopic necrosectomy in two patients with severe pancreatitis.
Other cases involved removal of esophageal blood clots and impacted food boluses.
No procedure-associated complications were reported.

Conclusions:

The OTSG is a valuable tool for the endoscopic removal of large particles, blood clots, and necrotic debris.
Preliminary data suggest the OTSG is effective and user-friendly for complex endoscopic interventions.
