The cardia is the interface between the stomach and esophagus in the human body, which opens when the human body eats and closes after eating to prevent the food in the stomach from refluxing into the esophagus. Due to chronic inflammation, unclean food and bad eating habits, the cardia can become malignant and develop into cardia cancer. Cardia cancer is one of the common malignant tumors. There is no specific symptom in early stage, and the diagnosis is mostly in late stage. The following are the common complications of pancreatic cancer: 1. Malignant mass in the advanced stage of pancreatic cancer, due to the increasing difficulty in swallowing with each passing day, resulting in long-term starvation leading to negative nitrogen balance and weight loss, has a direct impact on the incidence of complications and surgical mortality after pancreatic cancer resection. Virtually every patient with advanced pancreatic cancer with symptoms of obstruction has varying degrees of dehydration and loss of total body fluid due to their difficulty in eating through the mouth. Patients present with cachexia and significant water loss, manifested by high degree of emaciation, weakness, loose and dry skin, and a state of exhaustion.
2.Hemorrhage or vomiting of blood Part of pancreatic cancer patients have vomiting, individual pancreatic cancer patients have vomiting of blood due to tumor invasion of large blood vessels, and occasionally haemorrhage. Vomiting blood is generally a clinical symptom of advanced pancreatic cancer patients.
3.Organ metastasis If patients with advanced pancreatic cancer have metastasis of important organs such as lung, liver and brain, they may have respiratory difficulty, jaundice, ascites, coma and other symptoms specific to the corresponding organs. Patients with pancreatic cancer who have esophageal-tracheal fistula, metastasis of supraclavicular lymph nodes and other organs, laryngeal regurgitant nerve palsy and cachexia are all advanced pancreatic cancer.
4.Sympathetic ganglion compression cancer compression of sympathetic ganglion, then produce sympathetic nerve palsy (Homer syndrome).
