Patients were divided into groups based on the surgical sites, and postoperative feeding routes and timing of initiation of oral intake for groups were assessed. For the subset of patients fasting postoperatively for \u22657\u2009d, the proportion of patients prescribed target doses of energy (20\u2009kcal\/kg) and amino acids (0.8\u2009g\/kg) on postoperative d 7 were assessed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Surgical sites of 360\u2009296 study patients were: esophagus, 14\u2009784; stomach, 103\u2009339; colon\/rectum, 194\u2009049; liver, 19\u2009277; gallbladder\/bile duct, 8279; pancreas, 20\u2009568. The median postoperative day of oral intake initiation was: esophagus, seven; stomach and pancreas, four; colon\/rectum and gallbladder\/bile duct, three; liver, two. The proportions of fasting patients prescribed target doses of energy and amino acids on postoperative d 7 were: esophagus, 42.6% and 34.4%; stomach, 21.8% and 28.0%; colon\/rectum, 20.9% and 29.1%; liver, 21.2% and 22.5%; gallbladder\/bile duct, 31.0% and 33.4%; pancreas, 28.2% and 37.8%, respectively.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Oral intake after gastroenterological cancer surgery was started earliest in patients undergoing liver surgery and latest in patients undergoing esophageal surgery. Target parenteral energy and amino acid doses were prescribed to less than half of fasting patients.
