The effect of posture on the emptying of the intrathoracic vagotomized stomach.
Ten patients were studied at periods ranging from 6 months to 25 years after oesophagogastrostomy and gastric drainage. Gastric emptying studies and overnight gastric aspirates in both the supine and erect positions were carried out. Evidence was found in these patients of increased duodenogastric reflux and poor gastric emptying in the supine posture. All of the patients had gastritis, and some had gastric mucosal ulceration. These findings have led to the conclusion that in the supine posture the combination of duodenogastric reflux and poor gastric emptying leads to gastric mucosal damage.
