When someone gets diagnosed with pancreatic or gastric cancer, knowing the cancer’s stage is key. Endoscopic ultrasound (EUS) is a big help here. It’s a way to see how far the cancer has spread without a big surgery. EUS uses a special endoscope with an ultrasound probe. This probe makes clear pictures of the digestive tract and nearby tissues. Doctors can then check the tumor’s size, where it is, and if it’s touching other parts or lymph nodes. This info is vital for figuring out the cancer’s stage.
EUS helps doctors get a clear picture of the cancer. This leads to better treatment plans. It means patients have a better chance of getting the right treatment and living a better life.
What is Endoscopic Ultrasound (EUS)?
Endoscopic Ultrasound (EUS) is a cutting-edge medical procedure. It combines endoscopy and ultrasound to show detailed images of the digestive tract and nearby tissues. This tool has changed gastroenterology by giving clear views of the gastrointestinal wall and nearby areas.
The EUS procedure uses a flexible endoscope with an ultrasound transducer at the tip. This transducer sends high-frequency sound waves through the digestive wall. It creates detailed images of the tissues and organs around it. The procedure is done under sedation to keep the patient comfortable.
EUS Technology and Its Applications
EUS technology has improved a lot over time. It now includes Doppler technology. This lets doctors check blood flow through vessels. It’s key for looking at the blood flow of lesions and planning treatments.
