I thought the hospital could have been a little more helpful when I had some rather severe post operative constipation .But I was very pleased with the pre-op /op /post-op treatment i received from Mr Lewis.

I would advise anyone to put their care in Mr Lewis' hands he is efficient, professional, highly skilled, very kind and understanding. He has a great sense of commitment before and after procedure, this shows especially in his after care, I have has private surgery before but I have never received a emailed letter written after the procedure, on the actual day of surgery, explaining how the surgery went and what was accompliced , this was followed by an in depth emailed letter recalling my follow up appointment. I would recommend Mr Tryston Lewis most highly.
