Pancreatic drains do not have to stop flowing completely to be removed; they can be removed if the drainage is relatively small and there are no abnormalities. The main purpose of a pancreatic drain is to drain the accumulated exudate around the pancreas or pancreatic fluid from a pancreatic fistula out of the body, preventing the fluid from building up in the body, which can lead to infection. If there is no drainage coming out of the tube, or if there is little drainage and the amylase is low on retest and there are no abnormalities, the tube can be removed, and it does not have to stop flowing in order to be removed. If there is still excessive drainage secretion, it is necessary to extend the time, always observe the amount and color of drainage fluid, and promptly explain the situation with the doctor. Pancreatic drains should be kept open during the period, and they should be sterilized regularly. After the drainage tube is removed, the diet should be light, and the puncture site of the puncture tube should be cleaned well and care should be taken to avoid infection. If you feel unwell, you should go to the hospital in time and consult your physician for guidance.
