Technique of fine-needle aspiration under ultrasound guidance to diagnose pancreatic tumors is indicated when patients have suspected pancreatic tumors, abdominal lymph nodes... However, this method is not indicated for people with disorders coagulation PT < 60%, platelets < 50,000 and ascites.
1. Learn about pancreatic tumors
The pancreas in the human body consists of 3 parts, which are the head, body and tail. This organ is located below the stomach and in front of the spine. Weight about 80g, average length 15cm, height 6cm, thickness 3cm with 2 groups of cells:
Exocrine pancreatic cells: secrete enzymes into the small intestine to digest food; Endocrine cells: secrete a variety of hormones into the bloodstream to act on target organs. Pancreatic tumor is a general term used to refer to pathologies of the tumor type of the pancreas. Usually, pancreatic tumors are divided into 2 types, which are benign (congenital pancreatic tumors, pancreatic ringworm, pancreatic cysts) and malignant pancreatic tumors (pancreatic cancer).
2. Is pancreatitis indicated for ultrasound-guided fine-needle aspiration?
Ultrasound-guided fine-needle aspiration is a diagnostic technique used in the investigation of tumors or subcutaneous tumors under ultrasound guidance. With this method, the doctor will try to get enough tissue samples to analyze under a microscope, thereby diagnosing problems with inflammation, benign tumors or cancer. This technique will make it possible for patients to take samples without surgery, except in special cases.
Ultrasound-guided fine-needle aspiration is often used to diagnose lymph nodes, cysts in the neck; identify benign thyroid nodules or suspected malignancy; Examine the parotid salivary glands, submandibular salivary glands, and other areas of the neck, mouth, and throat.
For pancreatic tumors, the doctor will take a sample with a specialized needle. In case the organs are located deep in the body, the biopsy can be done under the guidance of ultrasound, computed tomography.... As for pancreatic tumors, intra-abdominal lymph nodes, a biopsy will be performed. through the skin to obtain patient samples under ultrasound guidance.
Ultrasonic-guided fine-needle aspiration technique to diagnose pancreatic tumor is indicated when pancreatic tumor or abdominal lymph node is suspected. But not indicated for people with coagulopathy PT < 60%, platelets < 50,000 and ascites.

3. Steps to perform fine-needle aspiration under ultrasound guidance to diagnose pancreatic tumors
Step 1: Prepare ultrasound machine with 3.5MHz probe; needle biopsy; sterile instruments; antiseptic, 2% lidocaine, pre-anesthetic. Step 2: Place an intravenous line and pre-anaesthetize the patient. Step 3: First, it is necessary to determine the entrance of the biopsy needle by ultrasound method. Select direct access to the tumor without penetrating the abdominal viscera. Step 4: Locate the needle puncture on the skin. Simultaneously, disinfect the needle puncture site, spread sterile acid and anesthetize the needle puncture site with 2% lidocaine. Step 5: The doctor performs a percutaneous needle puncture at an angle of 30 - 600 with the horizontal plane. Note that the needle direction coincides with the longitudinal plane of the ultrasound probe, and at the same time observe the needle tip on the ultrasound screen until the needle enters the correct position of the tumor. Step 5: Take the specimen and then withdraw the needle in the correct direction of entry. Then put the specimen in the storage vial.
4. Monitoring and handling of accidents
After conducting ultrasound-guided fine needle aspiration to diagnose pancreatic tumors, it is necessary to monitor the patient's pulse, blood pressure, needle puncture site as well as the patient's abdomen and respiratory status for 24 hours. In case of vascular puncture, it is necessary to stop the procedure, use vitamin K1, fresh frozen plasma if severe coagulopathy is present. In case of puncture through hollow organs such as stomach and intestines, stop the procedure and let the patient fast, closely monitor the abdomen. To ensure safety and get the most accurate diagnosis of pancreatic tumors, patients need to go to a reputable hospital to conduct fine needle aspiration under ultrasound guidance.
