Structural and functional aspects of the thoracic stomach.

The acid secretory and emptying function of the thoracic stomach was evaluated in 10 patients, following total oesophagectomy and gastric pull-up for oesophageal cancer. All patients had a Heinecke Mickulicz pyloroplasty. Endoscopic features and histological review of endoscopic biopsies were also studied in these patients. Acid secretion was higher in those with prolonged emptying. This was however, not statistically significant. Gastritis was more severe in those with prolonged emptying. Endoscopic diagnosis of gastritis was found unreliable while histopathology of endoscopic biopsy gave definite evidence of gastritis.
