Endoscopic ultrasonography--technique, orientation and diagnostic possibilities

Area of Science:

• Gastroenterology
• Medical Imaging
• Endoscopy

Background:

• Peroral endoscopic ultrasonography (EUS) is an evolving imaging technique.
• Newer prototypes aim to improve diagnostic capabilities for gastrointestinal conditions.

Purpose of the Study:

• To evaluate the utility of two new EUS prototypes (II and III) for examining abdominal organs.
• To assess the identification of organs and pathological lesions in patients with intestinal diseases.

Main Methods:

• Forty patients with various intestinal diseases underwent examination using Prototype II and III EUS.
• Standardized instrument positions were used for topographical orientation.
• Echographic patterns of identified organs and lesions were analyzed.

Main Results:

• The EUS prototypes successfully identified key abdominal organs: liver, gall bladder, common bile duct, pancreas, spleen, and kidneys.
• Pathological lesions were characterized by echo patterns consistent with external ultrasonography.
• The method provided additional anatomical and pathological information.

Conclusions:

• Current endoscopic ultrasonography is not a routine diagnostic tool.
• Newer EUS prototypes can offer valuable supplementary information to conventional endoscopy and external ultrasonography.
• EUS does not replace existing diagnostic methods but enhances their capabilities.
