Ultrasound diagnosis of pancreatic diseases

B-ultrasound is a medical examination item that patients often come into contact with at the time of treatment. Pancreatic B-ultrasound has diagnostic significance for pancreatic diseases. Basic Information Specialist classification: Digestive examination classification: ultrasound Applicable gender: whether men and women apply fasting: fasting Tips: You should fast for more than 8 hours before the test. Normal value Normal reference value of pancreatic head (adult) ≤ 2.5cm; The normal reference value of the measurement of the pancreas (adult) ≤ 2.0cm; Normal reference value of pancreatic tail (adult) ≤ 2.0cm. Clinical significance Clinically, it is widely used in the diagnosis of cardiology, gastroenterology, urology and obstetrics and gynecology. Indications for acute, chronic pancreatitis, pancreatic cancer and other diseases. High results may be diseases: islet cell carcinoid, neonatal hypoglycemia and hyperglycemia, pancreatic pseudocyst, pancreatic fistula, pancreatic encephalopathy syndrome, pancreatic stone disease, cloaca valgus, pancreatic trauma, ectopic pancreas Prepare and check the position before inspection: It should be fasted for more than 8 hours before the examination, especially in the morning after the breakfast is forbidden. Excessive gastro-intestinal gas, oral inflated tablets three days before the test, the day before the light into the slag diet, before taking a laxative. In the examination, you can drink 500-1000 ml of water to facilitate observation. The patient's position is generally in the supine position or in the semi-recumbent position. The upper body and the bed surface are at an angle of 30-45 degrees. Inspection process First, the inspection method 1. The pancreas examination routinely uses a 3.5MHz probe, of which the convex array probe has better effect. A 5.0MHz probe can be added to children and lean people. 2. The position of the examinee is taken in the supine position, the lateral position and the sitting position, and the standing position. 3. The probe is routinely examined along the long axis of the pancreas, and is supplemented with short-axis ultrasound scans of various parts of the pancreas. 4, in the left 8 ~ 9 intercostal spleen as the sound through the window, the tail of the pancreas is observed next to the splenic vein. 5, pay attention to the pancreas and surrounding organs such as: liver, spleen, gallbladder and biliary tract, stomach and duodenum, blood vessels around the pancreas and pancreas. 6, the extrahepatic biliary dilatation must observe the full length of the pancreas and biliary tract. 7, for the fat body type, pancreatic ultrasound imaging is not ideal, can be examined in the sitting position and right lateral position after the patient drinks 500 ~ 600ml. Second, check the content 1. The shape, size, contour and boundary of the pancreas. 2. The uniformity of the echo inside the pancreas. 3. The length and inner diameter of the pancreatic duct. 4, the main blood vessels around the pancreas, the common bile duct, the relationship between adjacent organs and the pancreas. 5. The location, number, distribution range, size, shape, edge, echo intensity of pancreatic lesions and their effects on surrounding organs and tissues. Not suitable for the crowd Patients with pancreatitis have severe abdominal pain, abdominal muscle tension, etc., which are not suitable for probe pressure examination. Adverse reactions and risks May cause abdominal pain.
