Summary
Endosonography (ES) is a key tool for gastrointestinal diseases, offering superior staging for cancers and lymphomas. Future developments promise higher resolution imaging and 3D reconstruction for improved diagnostics.
Area of Science:
- Gastroenterology
- Medical Imaging
- Oncology
Background:
- Endosonography (ES) has been a significant technique in managing gastrointestinal diseases for nearly 15 years.
- Two types of dedicated echoendoscopes are available, each with distinct advantages.
Purpose of the Study:
- To review the current applications and future potential of endosonography in diagnosing and staging gastrointestinal diseases.
- To highlight ES's role in characterizing submucosal lesions, investigating portal hypertension, and staging gastrointestinal cancers.
Main Methods:
- Review of existing literature and commercial echoendoscope technologies.
- Discussion of current diagnostic capabilities and emerging advancements in ES.
Main Results:
- ES is the most reliable technique for characterizing upper gastrointestinal submucosal lesions.
- ES provides superior T- and N-staging for esophageal and gastric carcinoma compared to CT scanning.
- ES-guided fine needle aspiration biopsy enables cytological diagnosis of mediastinal lymph nodes.
Conclusions:
- Endosonography is crucial for accurate staging of esophageal and gastric cancers, and gastric lymphoma.
- Advancements in resolution and 3D reconstruction will further enhance ES's diagnostic capabilities.
- ES is becoming indispensable for investigating portal hypertension and obtaining cytological samples from extraluminal lesions.
