Endoscopy and histology in inflammatory bowel diseases patients: Complementary or alternatives?—Author’s reply
Notice bibliographique
Résumé
We read with great interest the editorial: “Endoscopy and histology in inflammatory bowel disease patients: complementary or alternatives?”1 and we thank Dr. D’Amico et al. for insightful comments. The clinical relevance of an endpoint that combines histopathological and endoscopic assessments of mucosal healing versus only endoscopic endpoint is a matter of increasing debate. We have reported that PICaSSO endoscopic score can accurately predict histologic remission without having to combine both measures and this is of significant practical benefit.2 However, we fully agree that we need randomized controlled trials before translating into routine clinical practice. In addition, we were aware of limited use of PICaSSO score given that this was initially, developed and validated using iSCAN platform (Pentax) which is not available in all the endoscopy unit.3, 4 To overcome this limitation, we have recently investigated PICaSSO reproducibility and validation by using narrow band imaging (NBI) Olympus and linked colour imaging/blue-laser imaging (LCI/BLI), Fujifilm and this has been recently published.5 After a brief training for PICaSSO, we determined the interobserver variability (ICC) in a group of both experienced and less experienced endoscopists who were asked to score colonoscopies videos. In both Virtual Electronic Chromoendoscopy (VCE) platforms (NBI, LCI/BLI) the ICC for PICaSSO and its subscores (mucosal and vascular) were either good or very good, and most importantly, always numerically higher than for Mayo Endoscopic Score (MES) and Ulcerative colitis (UC) endoscopic Index of severity (UCEIS). Furthermore, in both NBI and BLI/LCI groups PICaSSO showed a strong correlation with histology. These results confirm that PICaSSO is accurate and reliable score on all available VCE platforms.5 However, we have already previously tested interobserver agreement in experienced consultant and trainees who had no prior exposure to Electronic Virtual Chromoendoscopy, by using a short training module (colonoscopy video library: 30 cases reviewed pre-training and 30 post-training) and PICaSSO revealed good interobserver agreement across all levels of experience in even non-expert setting reaching high ICC.3 Notably training modules, representative of all the endoscopic mucosal and vascular findings and with all the endoscopy platforms, are now available.3, 5 In conclusion, PICaSSO made an important point in the current debate that using high-definition endoscopes and VCE to enhance mucosal and vascular details, discrepancy between endoscopy and histology has become small. Histology plays still a crucial role for the clinical management of UC and we should not think that endoscopy will replace histology but be complementary. However, we hope to pave the way to motivate the implementation of VCE with targeted “smart biopsies “ and eliminate the use of MES = 1 as endoscopic remission which is imprecise. Finally, PICASSO is an accurate endoscopic score and each of mucosal and vascular items describe a single features of healing and active inflammation. Hence is suitable for a computer aided diagnosis for standardisation and endoscopy reading.6 MI is part-funded by the NIHR Birmingham Biomedical Research Centre.
