Bowel obstruction occurs in the late stage of pancreatic cancer mainly because of the metastasis of cancer cells, and it is easy to lead to the death of patients due to the complication of bowel obstruction, so it is better not to have bowel obstruction in the late stage of pancreatic cancer. Pancreatic cancer is one of the more malignant tumors in clinic, and in the late stage of pancreatic cancer, it may lead to intestinal obstruction due to the metastasis of cancer tissues to the duodenum, colorectum and other locations. Bowel obstruction may cause symptoms such as abdominal distension, stopping defecation, etc., and due to the large amount of blood accumulating in the intestinal lumen, it is easy to have complications such as hypovolemic shock, abdominal infection, intestinal necrosis, etc., which may lead to the death of the patient when it is serious, so it is better for pancreatic cancer to be free of bowel obstruction in the advanced stage. Advanced pancreatic cancer should also seek medical treatment for systemic treatment, and if intestinal obstruction occurs, it should be treated under the guidance of doctors to improve the prognosis of patients and prolong the survival time so as not to delay the condition.
