Overview
Endoscopic Ultrasound
- An endoscopic ultrasound (EUS) may be done in patients of gastrointestinal stromal tumors (GIST) presenting with signs and symptoms of abdominal pain, bleeding or obstructive symptoms.
- An EUS is considered more accurate than a CT scan in differentiating benign from malignant lesions.
- EUS-guided biopsy can also be used for diagnosing and staging of GIST. EUS can detemine the exact cell type and histopathological analysis of GIST
- Finding on an EUS includes:
- Mucosal ulceration or bleeding
- Smooth submucosal mass as hypoechoic mass
- Malignant GIST lesions present with:
- Heterogeneous mass >4 cm in size
- Irregular borders
- Intra and extraluminal growth
- Multiple cysts within the main lesion
- NOTE: Transcutaneous abdominal ultrasonography is not an imaging of choice for patients with suspected GIST. The presence of bowel gas and air filled viscera leads to poor image quality and inadequate visualization of abdominal organs.
