Professor Lodge is recognised internationally as one of the world’s most experienced liver surgeons. He has created a major hepatobiliary service, taking referrals from all around the UK and from abroad, including other major hepatobiliary centres. He provides a service for difficult liver tumours, often taking on cases considered to be inoperable elsewhere, and also deals with complex biliary strictures and injuries to the liver and bile ducts, often laparoscopically. He collaborates with surgeons abroad to bring the best techniques for patients having surgery in Leeds, not only for liver surgery. Following intensive training in Copenhagen, Peter has introduced modern Scandinavian techniques for improved weight loss surgery, with an emphasis on rapid recovery.
