Background And Aim:

Amber-red color imaging (ACI) is a novel image-enhanced endoscopic modality designed to improve visualization of blood-rich and submucosal structures. This study aimed to evaluate whether ACI improves in a clinical setting the clarity of identification of submucosal vessels, submucosal and muscle layers compared with white light imaging (WLI) in a standardized, video-based setting.

Methods:

In this prospective video-based study, third-space endoscopy clips, including endoscopic submucosal dissections (ESD) and peroral endoscopic myotomies (POEM), were analyzed. Each clip included matched WLI and ACI segments in randomized order. Six expert and six non-expert endoscopists independently rated vessel, submucosal and muscle layer clarity on a 10-point Likert scale.

Results:

Clips from 35 ESD and 20 POEM were analyzed. For submucosal vessels mean scores improved from 7.33 ± 0.89 to 8.55 ± 0.85 for non-experts and from 7.96 ± 0.86 to 9.63 ± 0.51 for experts (both p<0.001); non-experts with ACI outperformed experts with WLI (p<0.01). For submucosal layer non-experts improved from 6.37 ± 1.51 to 8.14 ± 1.29, and experts from 7.82 ± 0.87 to 9.80 ± 0.40 (both p<0.001), with non-experts achieving expert WLI performance (p=0.2). For muscle layer non-experts improved from 5.31 ± 1.16 to 7.12 ± 1.17, and experts from 7.75 ± 0.73 to 9.51 ± 0.57 (both p<0.001).

Conclusions:

ACI enhances recognition of submucosal vessels, submucosal and muscle layers in ESD and POEM, benefiting both experts and non-experts, and may serve as a valuable adjunct in third-space endoscopy.

Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers,...

Colors and Magnetism

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Color Vision

Color Vision

Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.

Anatomical Positions

Anatomical Positions

In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Anatomical Terminology

Anatomical Terminology

Knowledge of anatomy is essential to understand human biology and medicine. Anatomists and health care professionals use standard terminology to describe the human body with more precision and no ambiguity. Anatomical terms have mostly Greek and Latin-derived roots. Because these languages are rarely used in conversation, the meaning of words remains the same. Each term is made up of a root in between the prefixes and suffixes. The root of a term often refers to an organ, tissue, or condition,...

Anatomical Movements

Anatomical Movements

Anatomical movements refer to the various actions or motions that can be performed by the body's joints and muscles. These movements are described using specific terms to provide a standardized way of discussing and understanding the range of motion at different joints.
Here are some common anatomical movements:
Flexion and extension motions are in the sagittal (anterior–posterior) plane of motion. These movements take place at the shoulder, hip, elbow, knee, wrist,...
