This study aimed to evaluate and compare the knowledge and acceptability of histological assessment among gastroenterologists across the region. Methods: A cross-sectional survey among gastroenterologists in the Asia-Pacific region was conducted and compared against a previous Australian survey. The questionnaire assessed knowledge and attitude towards the role and application of histology in IBD practice. Statistical analyses were employed to compare scores and identify predictors. Results: A total of 221 gastroenterologists from 12 countries, including 77 (34.8%) from Australia, responded to questionnaire, with 185 (83.7%) completing the survey. The mean knowledge score was 9.8 ± 3.3 (51.6%). There was no significant difference in the average score among countries (P= 0.53). IBD specialist (P< 0.01), doctoral degree (P= 0.02), and regular participation in IBD multidisciplinary meetings (P= 0.01) were associated with higher scores. Most respondents (90.7%) agreed on the importance of histology in IBD. While 54.6% of Australians perceived the role of histology as established, only 37.0% of Asians respondents considered this similarly (P= 0.02). Histological activity alone minimally influences treatment escalation in patients with endoscopic remission, but achieving combined histo-endoscopic remission often leads to therapy de-escalation. Conclusions: Although gastroenterologists in the Asia-Pacific region are aware of the role of histology in IBD, their knowledge remains limited, and its clinical utility is not widely adopted. There is a need to promote the routine use of standardized histological assessment in IBD practice.MedicineArticleSCOPUS10.5217/ir.2024.000862-s2.0-10501212677222881956
