Validation of the paracetamol absorption test for measuring gastric tube emptying in esophagectomized patients versus gold standard scintigraphy

Scintigraphy is the gold standard for objective measurement of delayed gastric tube emptying after esophagectomy. The aim of this pilot study is to validate, by reference to scintigraphy, the paracetamol absorption test for measuring gastric tube emptying in esophagectomized patients.
