Abstract
The recent study published by Lee et al examined the discrepancies between endoscopic and histologic evaluations of mucosal inflammation in active ileal Crohn’s disease (CD). While this research contributes to our understanding of the limitations of current biopsy protocols, it raises several concerns about the generalizability of its findings, sample size, and methodology. One major limitation was the exclusion of patients with ileal strictures, ileostomies, or J-pouches, which reduced the applicability of the results to the wider CD population. Furthermore, the biopsy protocol's focus on single biopsies from specific locations may inadequately capture the patchy inflammation characteristic of CD. The study also uses histologic indices primarily developed for ulcerative colitis, which may not be suitable for assessing CD. It is recommended that multi-center studies be conducted and histologic indices specific to CD be developed to improve the relevance of future research. Additionally, researchers should consider the influence of treatment regimens on the findings. Addressing these limitations would enhance the clinical significance of the study and inform better diagnostic and therapeutic approaches for CD.
Core Tip: The recent study by Lee et al showed a significant discrepancy between endoscopic and histologic assessments in patients with ileal Crohn’s disease. However, the generalizability of these findings may be limited due to certain factors, such as the exclusion of specific patient groups, the single-center design of the study, and the potential under-sampling of inflammation. Future research should prioritize multi-center studies, creating Crohn’s specific histologic indices, and considering treatment regimen effects to improve our understanding and improve biopsy protocols for Crohn’s disease.
