Endoscopic microanatomy of anisakis. In vivo study

Area of Science:

• Medical Parasitology
• Gastroenterology
• Infectious Diseases

Background:

• Anisakiasis is a zoonotic disease caused by Anisakis nematodes.
• Infection occurs via ingestion of raw or undercooked seafood containing larvae.
• Accurate diagnosis and extraction are crucial for patient management.

Purpose of the Study:

• To evaluate the utility of in vivo endoscopic optical magnification for Anisakis sp. characterization.
• To visualize and characterize larval penetration points in the gastric mucosa.
• To assess the potential of this technique for improving endoscopic diagnosis and treatment of anisakiasis.

Main Methods:

• An in vivo endoscopic study was conducted.
• Optical magnification was employed for morphological evaluation of Anisakis sp.
• Detailed visualization of larval penetration sites in the gastric mucosa was achieved.

Main Results:

• Morphological characterization of Anisakis sp. was successfully performed using optical magnification.
• The penetration point of the parasite in the gastric mucosa was clearly visualized.
• The findings demonstrate the feasibility of detailed endoscopic visualization of the infection.

Conclusions:

• Endoscopic optical magnification offers a valuable tool for in vivo morphological evaluation of Anisakis sp.
• This technique can enhance the identification and facilitate the extraction of Anisakis larvae during endoscopy.
• Improved visualization may lead to optimized diagnostic and therapeutic outcomes for anisakiasis patients.
