Mr Rhys Thomas is a general surgeon at BMI Shirley Oaks hospital in Croydon.  His NHS base is Croydon University Hospital.  His interest is General surgery with particular sub-speciality focus on Upper gastrointestinal, laparoscopic (“keyhole”) surgery, hernia surgery of all types and surgical emergencies.

As part of his busy practice he operates on patients with symptomatic gallstones and other problems of the gallbladder and is the surgical lead for Upper GI services at Croydon University Hospital. 

A particular interest has is the enthusiastic and rapid surgical management of acutely presenting gallbladder pathology such as infections, pancreatitis and jaundice. 

At Croydon, he led the introduction of the acute gallbladder surgery pathway for managing these patients, with excellent results and a significant proportion of these patients are managed in this way; this service is also offered where possible at BMI Shirley Oaks hospital. 

Additionally, Mr Thomas has an interest in surgery for herniae of all types.  This includes groin (inguinal & femoral) and abdominal wall herniae.  He has a particular interest in recurrent abdominal wall herniae and complex herniae repair.

Mr Thomas believes that there is no “one size fits all” approach to managing patients with herniae and prefers to tailor his surgical approach to each patient following a detailed discussion of the risks, benefits and expectation of the patients prior to surgery.

This may involve a period of observation, open surgery or keyhole surgery, depending on the joint decision-making tailored for the patient. 

In addition to this, Mr Thomas has developed Acid reflux surgery at Croydon Hospital and leads the service.

He is a qualified JAG accredited upper GI endoscopist and scopes regularly at Shirley Oaks Hospital.  He sees patients with all types of general surgical emergencies at Shirley Oaks hospital.

This involved intensive training in Kingston, Croydon, Chichester and three years at the renowned Bariatric and Upper Gastrointestinal unit at St Georges Hospital, London under the mentorship of Professor Marcus Reddy. 

In 2015, he was appointed as Consultant Upper GI and General Surgeon at Croydon University Hospital, and he has developed the service there, supervising the expansion from one to three full time consultants.

Additionally, he maintains records of his cases with a regular audit of results, demonstrating low conversion rates to open surgery, low unplanned admission rates and low complication rates. 

Mr Thomas accepts referrals from all major insurers and has a particular interest in managing patients who are self-funding their treatment; he is a firm believer in addressing patient’s expectations and catering investigations and treatment to suit their needs.
