There are many kinds of general chest surgery, such as lung surgery, mediastinal surgery, chest wall surgery, esophageal surgery, and surgery for rib fractures in the chest wall. Regardless of which surgery is performed, it usually takes 7-9 days for the chest wall incision to heal, so it takes 7-9 days to recover from chest surgery. However, for patients who have chest drains left in place after surgery, i.e., the mouth of the tube will heal slowly only after the tube is removed, so the recovery may be longer. For patients who had thoracic rib fracture surgery, it takes longer for the bone to heal, and the recovery period takes 3 months for the rib to heal completely. For thoracic esophageal surgery, an esophagogram is performed after one week and no fistula is found in the esophagus before enteral nutrition from a duodenal nutrition tube can be performed. It takes 1-2 months after the re-imaging, if the leak is healed, before the nutrition tube can be withdrawn and after reaching transoral feeding.
