Evaluation of residual vascularisation in oesophageal substitution gastroplasty by surface oximetry-capnography and photoplethysmography. An experimental study.

Abstract

Important devascularisation of the fundus, theoretically incompatible with healing, occurs after gastroplasty. Operative photoplethysmography and surface measurements of pO2 and pCO2 are good ways of evaluating the level and degree of ischaemia in gastric tubes for oesophageal replacement.
