Patients with inflammatory bowel disease (IBD) may develop rheumatic diseases, particularly enterophatic spondyloarthritis (ESpA). Similarly, an IBD may develop in patients with SpA. Management of these patients in a dedicated ambulatory could be advantageous. We pioneered an integrated “GastroReumatology” ambulatory where a gastroenterologist and a rheumatologist with a long-lasting expertise in IBD and pondyloarthritis, respectively, simultaneously visit those patients referred for a suspected SpA. A total of 101 different patients with suspected or known IBD and/or a rheumatic disease were visited. A new diagnosis of ESpA was eventually achieved in 13 (12.9%) patients, and further 12 patients with an already known ESpA were referred for an appropriate management. No cases of IBD in those patients with an established rheumatic disease were observed. Early diagnosis of ESpA is possible in a “GastroReumatology” ambulatory.
