It has now been six weeks since my keyhole surgery for the removal of my gall bladder, performed by Mr Trystan Lewis. At all stages Mr Trystan Lewis explained what the procedure would be like and any possible complications that could occur. It gave me confidence to go ahead. I am very happy with the results and have had no problems since the operation. I would be very happy to recommend this surgeon.

Mr Lewis was friendly and highly professional. My appointment with him prior to the operation was very informative. in addition, a comprehensive letter summarising our conversation was supplied very shortly afterwards. The day of the operation went extremely well. My room was very comfortable. All members of staff were friendly, helpful and reassuring. Mr Lewis gave me a comprehensive briefing before the procedure. After the operation, my recovery proceeded well and in accordance with the advice I had been given. My post-op check with Mr Lewis confirmed that the bilateral hernia repair had been a complete success.
