Abstract
Radioactive scintiscanning using 81mKr (1), is a reliable nethod of measuring oesophageal transit-time uith very low doses of irradiation due to the very short life of the tracer and is particularly suitable for repeated examinations in children. we have observed 15 patients with severe caustic burns and long-term (up to 14 years) follow up is available for 12 of then. Severe grade III oesophagitis due to caustic compounds (usually following ingestion of strong alcali) frequently resulted in narrou strictures and rigidity of the oesophagus.
81mKr transit-time was used in all of them at several stages of the longstanding disease and served as criterim for assessing the development of the lesions and the loss of elasticity of the oesophageal wall as well as for monitoring medical or surgical treatment.
Results: no changes were observed in 3 children, improvement occurred in 7 and 2 extra cases were investigated only once.
Correlation with other techniques such as endoscopy and radiology, showed that 81mKr transit-time is more related to the functional status of the oesophagus than to the anatomical condition : one should use this non-invasive nost accurate technique for follow-up of caustic oesophagitis.
