Nuffield Health said Marc Lamah's practicing privileges had been ‘withdrawn' following an independent investigation.

A spokesperson said: ‘His conduct did not meet the standards of medical practice and governance we expect. Patient safety is our top priority and we hold all consultants to the highest standards.'

A BBC investigation revealed concerns about Lamah's complication rate and said one patient left with a twisted bowel following an operation he carried out.

Professor Katie Urch, chief medical officer for University Hospitals Sussex NHS Foundation Trust said: ‘Patient safety and the quality of care are the highest priorities for every NHS trust — and we uphold this responsibility with the utmost seriousness. All of our surgeons, along with the wider surgical teams, are subject to rigorous and continuous oversight in line with both national and internal standards. When concerns are raised about any individual surgeon, we conduct a thorough review of all relevant clinical data and patient feedback. If any risk to patient safety is identified, we take immediate action. Nuffield shared their full investigation with us. It found no concerns with regard to technical abilities, surgical practice or patient safety.'

The trust said the Nuffield Trust investigation had concluded: Lamah was capable and competent in his field, particularly in the management of major colorectal procedures; demonstrated an acceptable level of clinical competence, with no significant concerns regarding his ability to perform major surgeries safely; and found no direct evidence of substantial patient harm due to negligence or poor practice.

Commenting on the patient highlighted by the BBC, Professor Urch added: ‘We can't publicly discuss an individual's care, but we absolutely understand the distress and difficulty anyone living with ongoing complex health issues can face. Our clinical teams are dedicated to understanding their patients' needs and providing the highest standard of care. Whilst no medical procedure can guarantee a successful outcome, our teams strive for the best possible results every day – and if we ever have cause to think we could have done more for a patient we have robust systems, including the routine use of independent experts, to help us learn and improve.'
