Itching on the body after pancreatic cancer surgery can have several causes. Commonly, the patient is in an advanced stage, the patient has a high jaundice index, and recurrence after surgery causes obstructive jaundice, which can cause itching and is a reflection of a very critical condition. There are also itches that are dystrophic, seborrheic, allergic skin, and medically induced. For itch caused by recurrence of pancreatic cancer after surgery, it is necessary to go to a specialized hospital, consult a specialist, have an MRI analysis, re-drain the obstruction of the bile duct, and continue treatment in order to completely solve the problem. In the case of drug allergy, we must find the drug that caused the allergy, remove the drug allergen, and carry out anti-allergy medication, and most patients can improve their symptoms. For dystrophic and climacteric skin allergies and pruritus, dermatologists will give appropriate treatment according to the condition to resolve them.
