Mr Trystan Lewis

Consultant General Surgeon


"Spire St Anthonys provides an environment to give world class care to the patient."

Specialises in

I am a Consultant General Surgeon at Epsom and St Helier NHS Trust.

I specialise in using keyhole or laparoscopic surgery to treat conditions of the abdomen and abdominal wall. I treat conditions such as gallstones, acid reflux, skin lesions and lumps, pilonidal sinus and all types of abdominal wall hernia. I focus on minimally invasive surgery and same day surgical care to minimise the disruption and stress of surgery.

I have been qualified for 16 years, and have specialised in laparoscopic or keyhole surgery of the abdomen. I started my surgical training in North West Thames, completing a PhD at Imperial College studying innovations in surgical techniques and laparoscopic technical skills. I completed my surgical training in South West Thames, before being appointed as a consultant general surgeon at Epsom and St. Helier NHS Trust. I am the clinical lead for the Surgical Ambulatory Care Unit and am passionate about surgical education and training the surgeons of tomorrow.
