Since the normal structure of the cardia and part of the esophagus are removed during esophageal and cardia cancer surgery, the structure of the upper gastrointestinal tract will change significantly after surgery, so patients will have more discomfort after surgery, such as belching and acid reflux, poor feeding, postprandial fullness, chronic pain of the incision, etc. After surgery for esophageal cancer and cardia cancer, the cardia is removed or sutured shut, and the artificial joint (anastomosis) lacks natural diastolic and contractile functions, so the acid reflux of residual gastric secretion is inevitable, and patients should gradually treat it psychologically and calmly, and then they can seek help to relieve symptoms. Postoperative diet: 1. After surgery, since the thoracic stomach is usually sewn into a tube, the volume is small, so it is appropriate to eat less and more meals. 2.Because of the poor emptying ability of the thoracic stomach, it is advisable to walk appropriately after meals, relying on the effect of gravity to promote the emptying of the thoracic stomach and reduce postprandial fullness. 3.Because the anastomosis lacks diastolic function, it is advisable to chew and swallow slowly to avoid blockage of the anastomosis. Prevention of postoperative reflux esophagitis: 1. At rest, adopt a low semi-sloping position of 20-30°, so that reflux can be reduced by the action of mechanical gravity; 2. Take oral acid-control drugs and gastrointestinal motility drugs, the former reducing the secretion of gastric acid and the latter promoting the downward emptying of gastric juice. The prevention and treatment of chronic pain of chest incision: The large chest incision requires propping up the intercostal space and/or cutting off the ribs, which will damage the intercostal nerves. Symptoms. However, for some patients with more severe symptoms, topical analgesic creams can be used to relieve the symptoms, such as Furtalin ointment. For postoperative patients with esophageal or cardia cancer, follow-up examinations and follow-ups should be determined according to the pathological examination results after surgery. After 3 years, the above examinations can be done twice a year; after 5 years, the above examinations can be done once a year.
