Pancreatic puncture biopsy process

Pancreatic puncture examination is a common examination method. When a malignant tumor of the pancreas is suspected, CT or other examination methods often cannot confirm the diagnosis. Pancreatic puncture biopsy can be considered. This is a more direct examination method. Its accuracy rate is relatively high, which can be as high as 90% or more. When conducting this examination, some precautions should be understood. Patients should understand them before and after the examination and strengthen good care.

Pancreatic biopsy procedure

If pancreatic malignancy is suspected and ultrasound and CT examinations cannot confirm the diagnosis, pancreatic puncture histological examination should be considered. The main process of puncture biopsy is: after disinfection, perform pancreatic puncture under the guidance of laparoscopy and take a small amount of living tissue for biopsy. Once tumor cells are found, the disease can usually be diagnosed. After the diagnosis, surgical treatment is needed as soon as possible, followed by chemotherapy and radiotherapy under the guidance of a doctor. Go to the hospital for regular check-ups, and if cancerous tissue metastasis is found, appropriate treatment should be given.

The pancreas is a retroperitoneal organ, and the puncture path often needs to pass through the stomach or liver. The surrounding anatomical structure is complex, and the risk of complications is higher than that of intra-abdominal organ puncture. It is considered one of the most difficult puncture biopsies. With the improvement of ultrasound guidance technology and puncture equipment, the success rate and safety of pancreatic puncture biopsy have been significantly improved, and the success rate of sampling can reach more than 90%, playing an important role in the accurate diagnosis and condition assessment of pancreatic diseases.

Indications

Ultrasound-guided biopsy is suitable for focal or diffuse pancreatic lesions visible on ultrasound.

1. Differentiation of benign and malignant pancreatic focal lesions, pathological classification, etc.

2. Diffuse pancreatic enlargement, the cause must be identified (such as chronic pancreatitis, autoimmune pancreatitis and diffuse pancreatitis).

diffuse pancreatic cancer).

3. Unexplained pancreatic function damage and rejection after pancreas transplantation.

Contraindications

1. Those who are in poor general condition, cannot tolerate puncture, and cannot coordinate breathing.

2. Those with obvious bleeding tendency and coagulation dysfunction.

3. Patients with acute pancreatitis or acute exacerbation of chronic pancreatitis.

4. Patients with severe liver cirrhosis and massive ascites.

5. The pancreatic duct is significantly dilated and cannot be avoided, and puncture may cause pancreatic fistula.

6. Patients with digestive tract obstruction and gastrointestinal dilatation.

7. The tumor is very rich in blood vessels or around it, and there is no safe puncture path.
