Ultrasound endoscopy of the pancreas is relatively accurate. Ultrasound endoscopy involves the placement of an ultrasound probe at the tip of the endoscope, which allows both direct observation of the morphology of the digestive tract lumen through the endoscope and real-time ultrasound scanning to obtain histological structural characteristics of the duct wall level and ultrasound images of the surrounding neighboring organs, thus further improving the diagnostic level of both endoscopy and ultrasound. The pancreas is an organ located in the retroperitoneum without bony tissues, and general physical examination and ordinary imaging have limitations in diagnosing pancreatic diseases, limiting the early diagnosis of pancreatic diseases. Ultrasound endoscopy provides high-resolution visualization of the pancreatic parenchyma and can often accurately screen for pancreatic problems. However, it is worth noting that ultrasound endoscopy-guided puncture of the pancreas for cancer is also risky because the pancreas is more blood-rich, and there is a higher risk of pancreatic fistula or vascular hemorrhage if the puncture needle hits a blood vessel or pancreatic duct. It is recommended that patients needing ultrasound endoscopy go to a regular hospital.
