Fixation and Sectioning

Fixation and Sectioning

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Special Staining Techniques

Special Staining Techniques

Specialized staining techniques play a vital role in microbiology by enabling the visualization of specific bacterial structures that remain undetectable with standard microscopy methods. These techniques not only enhance the structural visualization of bacterial cells but also provide critical insights into their pathogenicity and classification. Additionally, they support diagnostic and research endeavors in microbiology by identifying key bacterial features.Capsule Staining for Virulence...

Simple Staining Technique

Simple Staining Technique

OverviewStaining techniques in microscopy enhance the visualization of microorganisms by increasing contrast and allowing the differentiation of cellular structures. Simple staining is one of the fundamental methods used to observe the basic morphological characteristics of microorganisms, including their size, shape, and arrangement. This method relies on the application of a single dye to stain the entire cell, producing a clear contrast between the cell and the background.FixationFixation is...

Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

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

Endoscopic Procedures II: Colonoscopy

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 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 to...

Area of Science:

Gastroenterology and Endoscopic Imaging

Background:

Conventional white light endoscopy has limitations in detecting gastrointestinal pathology, with a miss rate up to 25% for small and flat lesions.
Advanced imaging techniques, including chromoendoscopy, enhance visualization and detection of neoplastic lesions throughout the gastrointestinal tract.

Purpose of the Study:

To review dyes, indications, and advanced endoscopic imaging methods in chromoendoscopy.
To critically evaluate the evidence supporting chromoendoscopy in current practice, focusing on inflammatory bowel disease and Barrett's oesophagus (BO).

Main Methods:

Discussion of various chromoendoscopic techniques, dyes, and advanced imaging modalities.
Review of existing clinical evidence and applications in gastrointestinal endoscopy.

Main Results:

Chromoendoscopy, especially with magnifying endoscopy, improves detection of neoplastic lesions in ulcerative colitis and Crohn's colitis.
It aids in evaluating Barrett's oesophagus (BO) for dysplasia and characterizing suspicious lesions.
The technique helps delineate the extent of neoplastic lesions for endoscopic resection.

Conclusions:

Chromoendoscopy is a valuable tool for enhancing the detection, characterization, and management of gastrointestinal neoplastic lesions.
Its application is particularly beneficial in managing inflammatory bowel disease and Barrett's oesophagus.
Advanced endoscopic imaging techniques improve diagnostic accuracy and patient outcomes in gastrointestinal oncology.
