Abstract:
International guidelines recommend dysplasia surveillance in IBD. Aim To compare endoscopic techniques for dysplasia surveillance Methods We searched MEDLINE, Embase, CENTRAL for randomised trials through May 2019. We estimated odds ratios (ORs) for binary and mean differences (MDs) for continuous outcomes, using frequentist random‐effects network meta‐analysis. We assessed study risk of bias and appraised evidence certainty using GRADE. Results Eighteen trials (2638 participants) were included. Standard definition white‐light endoscopy (OR 0.44, 95% CI 0.26‐0.73; high certainty ) and i‐SCAN (OR 0.47, 95% CI 0.25‐0.90; moderate certainty ) had lower odds of detecting neoplasia than chromoendoscopy. Fujinon intelligent colour enhancement (FICE), standard definition white‐light endoscopy and i‐SCAN had lower odds for this outcome than full spectrum high definition white‐light endoscopy (ORs 0.02 to 0.15; low certainty ). Standard definition white‐light endoscopy had lower odds of detecting nonpolypoid neoplasia than full spectrum high definition white‐light endoscopy, narrow band imaging, chromoendoscopy and high definition white‐light endoscopy (ORs 0.01‐0.14; moderate certainty ). Full spectrum high definition white‐light endoscopy ranked as the best technique for both outcomes ( moderate certainty ). Standard definition white‐light endoscopy had lower odds of detecting neoplasia by target biopsy (OR 0.27, 95% CI 0.08‐0.91) and had shorter procedure time (MD −14.81 minutes, 95% CI −25.03, −4.06) than chromoendoscopy ( moderate certainty ). Conclusions Chromoendoscopy, high definition white‐light endoscopy, narrow band imaging, autofluorescence, FICE and full spectrum high definition white‐light endoscopy may be comparable for dysplasia surveillance. Standard definition white‐light endoscopy and i‐SCAN probably provide lower yields for neoplasia identification. Full spectrum high definition white‐light endoscopy may represent the first‐line approach.
