What is EUS?
Endoscopic Ultrasound (EUS) combines endoscopy and ultrasound to obtain detailed images of the digestive tract and surrounding organs. A specialized endoscope with an ultrasound probe is inserted through the mouth or rectum to visualize the esophagus, stomach, pancreas, and bile ducts. This advanced imaging technique provides high-resolution images, enabling accurate diagnosis and staging of gastrointestinal and pancreatic diseases. EUS is particularly useful for detecting small tumors, cysts, and lymph nodes that may not be visible on other imaging modalities, making it an essential tool in gastroenterology and oncology.
How Does It Help?
Evaluation of Pancreatic Diseases
Evaluation of Pancreatic Diseases
EUS provides detailed images of the pancreas, allowing for the detection of tumors, cysts, and inflammation. Fine-needle aspiration (FNA) can be performed during the procedure to obtain tissue samples for further analysis.
Staging of Gastrointestinal Cancers
Staging of Gastrointestinal Cancers
EUS is instrumental in assessing the extent of gastrointestinal cancers. It helps determine the depth of tumor invasion and involvement of nearby lymph nodes, aiding in accurate staging and treatment planning.
Diagnosis of Biliary and Gallbladder Conditions
Diagnosis of Biliary and Gallbladder Conditions
EUS offers precise imaging of the bile ducts and gallbladder, facilitating the diagnosis of stones, strictures, and other abnormalities. It provides a non-invasive alternative to traditional diagnostic methods.
How Is It Done?
EUS is a minimally invasive procedure that provides detailed imaging and diagnostic capabilities. It combines the benefits of endoscopy and ultrasound to enhance diagnostic accuracy.
Preparation
Preparation
Patients are usually required to fast for several hours before the procedure. Detailed instructions on medication adjustments and fasting are provided. A comprehensive medical evaluation is conducted.
Procedure
Procedure
During EUS, a sedative is administered for comfort. The endoscope with an ultrasound probe is carefully advanced to the target area. High-frequency sound waves create detailed images, and if necessary, tissue samples are obtained using fine-needle aspiration.
Post-Treatment
Post-Treatment
After EUS, patients are observed for any immediate complications. Recovery instructions, including dietary guidelines and activity restrictions, are provided. Follow-up appointments are scheduled to review results and plan further treatment if necessary.
