Endoscopic Ultrasound (EUS)

EUS and EUS-guided procedures may be used to:

• Check damage to tissues due to swelling or disease.
• Find out if cancer is present or has spread to lymph nodes.
• See how much a cancerous tumor has spread to other tissues. A cancerous tumor also is called a malignant tumor.
• Identify the stage of the cancer.
• Provide more-detailed information about lesions found by other imaging technologies.
• Take out fluid or tissue for testing.
• Drain fluids from cysts.
• Deliver medicine to a targeted region, such as a cancerous tumor.

Key Benefits of Endoscopic Ultrasound:

• High Precision Imaging: Because the ultrasound probe is placed directly inside the digestive tract, it provides highly detailed, high-resolution images of internal organs, including the pancreas, gallbladder, and lymph nodes.
• Targeted Tissue Sampling (EUS-FNA): EUS enables fine-needle aspiration (FNA) to collect tissue or fluid samples from suspicious lesions or cysts for precise pathology testing, which is vital for cancer diagnosis.
• Accurate Cancer Staging: EUS is crucial for determining how deeply a tumor has grown (e.g., esophageal, rectal, gastric) and whether it has spread to surrounding lymph nodes.
• Minimally Invasive Diagnosis & Treatment: EUS can treat conditions such as draining pancreatic cysts, injecting medications into specific areas, and performing nerve blocks for chronic pain.
• Safer Alternative to Surgery: Being a minimally invasive, outpatient procedure, it carries fewer risks than surgical exploration.
• Detailed Assessment of Digestive Disorders: It helps diagnose complex issues like chronic pancreatitis, gallstones, and tumors.
