The risk of pancreatic ductal papillary mucinous tumor surgery exists, mainly including local reaction and systemic reaction. 1. Local reaction: Incomplete disinfection of the wound during surgery for pancreatic ductal papillary mucinous neoplasm may lead to wound infection and inflammation, which is manifested as redness and pus in the wound; in severe cases, there will be the risk of poor wound healing and bleeding. 2. Systemic reaction: if the tumor of pancreatic ductal papillary mucus is relatively large, improper operation may be combined with secondary infection and lead to generalized swelling; some patients may have nausea, vomiting, unstable respiration, weak pulse, and other risks after the operation. After surgery for pancreatic ductal papillary mucinous tumor, patients need to pay attention to a reasonable diet, which should be light and nutritious to promote recovery and shorten the course of the disease, and it is recommended that patients follow the doctor’s instructions, and do not make blind decisions on their own, so as not to delay the condition.
