The objective analysis is based on the specific causes of the enlargement of the head of the pancreas. If the head of the pancreas is accompanied by malignant tumor proliferation such as malignant tumor of the pancreas, which causes enlargement of the head of the pancreas, the enlargement of the head of the pancreas cannot be completely self-healed if the tumor lesion is not surgically removed and the surrounding lymph nodes are cleared. With the prolongation of time, tumor cells can invade the surrounding blood vessels and nerves along with blood vessels and lymphatic vessels, causing progressive increase in the volume of the pancreatic head, thus causing blockage of bile ducts and pancreatic ducts, and patients can have serious complications such as obvious yellow staining of skin and sclera. If the enlarged pancreatic head is caused by local inflammation, the enlarged pancreatic head can gradually absorb and recede after the inflammation in the patient’s body is completely controlled, so as to completely heal itself and achieve a better treatment effect.
