Mr Allenby-Smith is a Consultant General and Upper GI Surgeon based in Poole. He specialises in laparoscopic (keyhole) surgery. His main expertise is in treating gall stones, acid reflux and hernia surgery.

Following his medical degree in Southampton, Mr Allenby-Smith focused his career around upper gastrointestinal surgery. Training across the south coast specialist centres, he focussed on laparoscopic surgery for a range of conditions. During his final year training in Southampton he further developed skills in the laparoscopic management of oesophageal cancer and bariatric (weight loss) surgery. He became a Fellow of the Royal College of Surgeons of England in 2010 and started as a Consultant General and Upper Gastrointestinal Surgeon in Poole Hospital in 2011. After a couple of years he was appointed as Clerkship Director and Assistant Professor at St George’s University, Grenada.

Mr Allenby-Smith has set up a specialist clinic in Poole treating patients with acid reflux and heartburn. Often this may be treated with medications but he also offers a new day case treatment called Stretta. Other patients may benefit from fundoplication surgery to prevent their reflux. Mr Allenby-Smith performs a range of treatments for Gall Stones from endoscopic treatment (ERCP) to laparoscopic surgery to remove the Gall Bladder (cholecystectomy).
