Synopsis
Mr Deepak sees patients privately at The Harley Street Clinic and The Princess Grace Hospital in Marylebone, both part of the HCA Group of hospitals. He remains active within the NHS and practices as a Consultant in HPB and General Surgery at the Royal London Hospital, part of Barts Health NHS Trust, one of the largest NHS Trusts in the country.

His clinical research interest has been to facilitate early diagnosis and treatment in HPB cancers. He investigated potential diagnostic biomarkers in urine for pancreatic cancer. His seminal paper established urinary proteomics as a strategy for the investigation of biomarkers for pancreas cancer. In September 2019, Pancreas Cancer Research Fund funded a £1.6M clinical study that would validate the accuracy and reliability of a urine test in detecting pancreatic cancer at an early stage.
He has multiple peer-reviewed publications in HPB and General Surgery and is a tutor and mentor to undergraduate, post-graduate trainees and nurses.
He is driven by quality improvement in surgery and is instrumental in setting up the Hot Cholecystectomy Pathway. This facilitates immediate/early gallbladder surgery for suitable cases presenting as an emergency with symptomatic gallstones. He helped establish an enhanced recovery programme after HPB cancer surgery to advance postoperative care.
He is motivated and focused on developing high-performing surgical teams to improve the quality of surgical care and enhance the patient experience.
