The conference was the first combined meeting of the Association of Upper Gastrointestinal Surgeons (AUGIS), the British Association for the Study of the Liver (BASL), the British Society of Gastroenterology (BSG) and the British Association for Parenteral and Enteral Nutrition (BAPEN), which replaced each association's annual meeting in 2012.
The event took place in June at the ACC Liverpool and attracted 3,500 delegates.
Following an evaluation, the event is set to return in 2015 and hopes to build on its success with the addition of a fifth association, which will help to attract an estimated total of 5,000 delegates, 700 exhibitors, 1,000 posters, 420 speakers and 97 sessions over four days.
Lynn Samson of PCO MCI Glasgowsaid: "The joint event created a more extensive scientific programme with 26 break-out sessions running at any one time. It overwhelmed some delegates and there were too many programme clashes. A very likely solution will be to incorporate a hybrid model in 2015."
