Pancreas puncture is the process of puncturing the wall of a given organ of the digestive system with a therapeutic or diagnostic purpose. Therapeutic purposes in this procedure may be associated with the administration of medications or by the suction of fluid( blood, pus, etc.).But the pancreas is an organ sensitive enough to external influences( in particular, to mechanical injuries), in connection with this, the puncture is practically not performed, solely, with therapeutic purposes. However, therapy with the help of this method is quite appropriate to combine with the diagnosis.
Diagnostic puncture is performed, as a rule, locally in the place of the presence of a neoplasm or suspected neoplasm. Thus, the main purpose of pancreatic puncture is the determination of the benign or malignant nature of the tumor. In other cases, except for the suspicion of cancer, this procedure, in practice, is never appointed. The most appropriate procedure( puncture biopsy) under the supervision of ultrasound or other diagnostic devices.
How do pancreas puncture?
Puncture biopsy of the pancreas is done to determine the nature of the neoplasm( benign or malignant) and the stages of the disease course. For the biopsy, depending on the location of the neoplasm and the nature of the study, cutting, aspiration or modified aspirating needles are used.
Stages of pancreas preparation and puncture:
- Before the procedure for six hours, the patient must refuse to eat.
- For the procedure, the needle is usually inserted through the duodenum, if the localization of the tumor allows it.
- Conduct local anesthesia.
- Introduction of the needle is carried out slowly and under the control of the ultrasound of another scanning cavity of the apparatus. The data will allow maximum localization of the puncture and minimizes mechanical damage to the pancreas.
- Biological material is collected( liquid or part of the neoplasm tissue) for subsequent laboratory tests. As a rule, at the same time, with the removal of the material for diagnosis, an antiseptic and / or antibiotic preparation is administered at the puncture site.
After the procedure, it is recommended to remain at rest for at least two hours.
