Abstract
Controversy still exists about the need for pyloric drainage procedures (pyloroplasty or pyloromyotomy) after esophagectomy with esophagogastrostomy and vagotomy. Although pyloric drainage may prevent postoperative delayed gastric emptying, it may also promote bile reflux into the oesophagus. We analysed pyloric drainage methods for their potential effect on gastric outlet obstruction and bile reflux in patients undergoing esophagectomy.
