By the early 1980s, the ileal pouch procedure had become part of specialist colorectal surgical practices worldwide. In the United States the Australian-born surgeon Victor Warren Fazio at the Cleveland Clinic and Roger Dozois at the Mayo Clinic began publishing on the operation in the early 1980s greatly increasing its diffusion and there was generous co-operation among these units, St Mark's and colorectal departments in Canada (Zane Cohen), France (Professor Rolland Parc) and Italy (Dr Gilberto Poggioli).
