What is the main purpose of an endoscopic ultrasound?

The main purpose of an endoscopic ultrasound is to evaluate pancreatic diseases. This technique combines endoscopy and ultrasound to provide detailed images of the pancreas, bile ducts, gallbladder, and surrounding tissues. Endoscopic ultrasound is particularly useful for diagnosing conditions like pancreatitis, pancreatic tumors, and cysts, as it allows for close examination of the pancreas' structure and surrounding lymph nodes. Additionally, it can help identify other gastrointestinal issues that may be related to pancreatic disease.

Other options may have some relevance but do not directly capture the core use of endoscopic ultrasound. For instance, while it can visualize the intestines and potentially aid in assessing certain liver conditions, its primary strength lies in its capacity to accurately evaluate pancreatic issues. Biopsies can indeed be performed during an endoscopic ultrasound, but the overarching purpose of the procedure is to facilitate a thorough assessment of pancreatic health.
