Dumping syndrome in the intra-thoracic stomach.

Thirty seven patients who survived at least 6 months after oesophagectomy and cervical oesophagogastrostomy for benign and malignant diseases of the oesophagus were evaluated for dumping syndrome. Twenty two of these patients had a pyloroplasty and fifteen had no drainage procedure. All these patients were subjected to a dumping provocation test. Evidence of dumping was noted in four patients, all having a pyloroplasty. Clinically, these four patients had mild symptoms which improved with dietary adjustment. We conclude that dumping does occur following thoracic transposition of the stomach and seems to occur more in patients with pyloroplasty than those without it.
