Twenty-Four-Hour pH Monitoring Study of Gastric Tube Used for Reconstruction After Esophagectomy for Esophageal Carcinoma

The gastric tube has often been used as a replacement for the esophagus after the resection of an esophageal carcinoma. The acidity of a completely vagotomized stomach has been estimated to be not high enough to cause a peptic ulcer. However, we experienced a few cases of peptic ulcer of the postoperative gastric tube or duodenum. In this study, we assessed the dynamics of gastric acid secretion in patients with esophageal carcinoma before and after esophagectomy.

The Influence of Thoracic Duct Resection on Postesophagectomy Hemodynamics: An Analysis of Changes of Atrial Natriuretic Peptide and Brain Natriuretic Peptide

An en bloc resection of esophageal cancer is one of the most radical forms of esophagectomy, and includes the resection of the thoracic duct. In a previous publication [1], we examined the hemodynamic changes in 24 patients whose intrathoracic ducts were resected during esophagectomy for esophageal cancer and 3 developed severe tachycardia or postoperative shock, recovering after a massive infusion of plasma. Fluid balance analysis revealed that during surgery and for 48 h after, much more fluid was necessary for en bloc resection patients.
