Patient Testimonials
"Professor Viswanath was extremely professional and reassuring throughout the whole process. He explained the LINX procedure clearly and I felt I was in very capable hands. The LINX device is working very well and has made a real difference to the reflux symptoms I was experiencing before surgery. Recovery has gone well and I’m very pleased with the outcome so far. I would have no hesitation in recommending Professor Viswanath to anyone considering the procedure. Thank you to him and his team for the excellent care I received" -
