Multimodal Endoscopic Ultrasound in the Evaluation of Indeterminate Upper Gastrointestinal Wall Thickening

Condition(s) studied

Investigational drug(s) / intervention(s)

Endoscopic ultrasound: Multimodal Endoscopic Ultrasound including; conventional B-mode EUS Assessment, doppler evaluation, EUS elastography and Selective EUS-Guided Fine-Needle Biopsy (EUS-FNB)

Study summary

Multimodal endoscopic ultrasound can help to differentiate between benign (non-cancerous) and malignant (cancerous) causes of thickening of the upper digestive tract wall.

The main questions this study aims to answer are:

How accurate is multimodal endoscopic ultrasound in identifying the cause of upper digestive tract wall thickening?

Can using several ultrasound techniques together improve diagnosis when standard tests are unclear?

Participants are adults who have upper digestive tract wall thickening seen on scans such as computed tomography (CT) or magnetic resonance imaging (MRI).

Participants will:

Undergo upper endoscopy followed by endoscopic ultrasound and tissue sample taken during the procedure when needed followed by using biopsy results or clinical follow-up to confirm the final diagnosis

This study aims to improve early and accurate diagnosis and help guide proper treatment decisions for people with unexplained upper digestive tract wall thickening.

Eligibility
