Dr Fraser was the 1st doctor in the UK to perform the Stretta endoscopic anti-reflux procedure in 2012. He was the 1st doctor in Scotland to perform Stretta (in 2016).
Stretta is a minimally invasive, endoscopic procedure that takes approximately 45-60 minutes to do. The Stretta catheter is passed through the mouth, there are no visible cuts or scars as a result of the procedure. Patients typically go home 1-2 hours after the procedure. Most patients are able to return to work and their normal activities including exercise, the day after treatment, so there is minimal interruption to everyday life.
A specially designed, flexible, catheter is passed through the mouth, into the oesophagus, and is positioned at the lower oesophageal sphincter (LOS) valve, which is located at the junction of the lower oesophagus and stomach. The catheter places 4 small needles into the muscle of the LOS and delivers radiofrequency energy to the muscle. Several areas in the region of the LOS and the top of the stomach (cardia) are treated in sequence.
