After surgery for oesophageal (gullet) or gastric (stomach) cancer, patients are routinely fed by means of a small feeding tube into the intestine (jejunostomy, JEJ) while they are in hospital. Current practice is to stop feeding once the patient leaves hospital, although the tube is left in place for the first 6 weeks. Most patients lose weight after surgery and have to learn to adjust to new eating habits and behaviours. A few patients have the JEJ feed restarted because of nutritional problems and this requires a further inpatient stay.
