Substitution of thoracic oesophagus by interposition of a pedicled gastric tube, preserving LES function: clinical and histological follow-up.
Assessment of clinical evolution and histological findings in a group of animals experimentally operated on to substitute the thoracic oesophagus with a gastric tube. Six piglets underwent oesophageal replacement with a gastric tube, constructed from the greater curvature of stomach and pedicled on the gastroepiploic vessels, which was interposed between the oesophageal stumps. At follow-up, all animals were found to be growing and eating normally, apart from case no 1 (stenosis of the lower oesophageal anastomosis). Ph-metry showed a neutral pH on the gastric tube. Postmortem histological analysis of the gastric tube and native oesophagus samples did not show any significant lesions, except in case no 1 (inflammation of the gastric tube and upper oesophagus due to food stasis). The technique of substitution of the oesophagus with an interposed pedicled gastric tube can be a breakthrough in existing surgical methods of oesophageal replacement.
