Pancreatic tail occupancy requires surgical removal of pancreatic occupying tissue. Pancreatic tail occupation is a tumor in the tail of the pancreas, which may be benign or malignant, and is mainly treated by surgical removal of pancreatic occupying tissues. The benign or malignant nature of pancreatic tail occupation should be analyzed and comprehensively evaluated by the doctor in conjunction with pathological biopsy. In case of malignant pancreatic tail occupation, postoperative chemotherapy and radiotherapy should be used to enhance the treatment effect. If pancreatic tail occupation is detected in the examination, it is recommended to cooperate with professional doctors as soon as possible to formulate a reasonable surgical treatment plan and operate early to maximize the effect of surgery. After surgery, we should also improve the pathological biopsy to determine the type of pancreatic caudal occupancy, and actively take follow-up treatment measures.
