ABSTRACT

Aim:

Early diagnosis and treatment of Colorectal Cancer can improve outcomes. Polypectomy with colonoscopy has failure and incompletion rates with risk of aerosol-generation. Computed Tomographic Colonography, second investigation, is limited by radiation exposure and aerosol generation. Colon Capsule endoscopy is a novel technique without gas insufflation, therefore avoiding the discomfort and aerosol- generation. Our aim is to compare the yield of the CCE with CTC in CRC and polyps in patients with positive stool tests or diagnosed colorectal lesions.

Methods:

Review followed PRISMA standards. Electronic database (EMBASE, MEDLINE, PubMed, CINAHL) searched for RCTs and Observational studies. MedCalc Statistical Software used for the synthesis of results. Primary (Per-Lesion and Per-Patient sensitivity analysis) and secondary (Other lesion and completion rate sensitivity analysis) outcomes measured using a random-effect model.

Results:

We found one RCT and three observational studies. Per-Lesion Sensitivity Analysis of CCE versus CTC showed overall effect of 1.903 (0.990- 1.937), p-value-0.057. Per-Patient Sensitivity Analysis of showed overall effect of 1.928 (0.995-1.892), p-value-0.054. Other lesions Sensitivity Analysis showed overall effect of 0.810 (0.121-161.995), pvalue- 0.418. Completion Rate Sensitivity Analysis showed overall effect of -0.419 (0.526-1.516), p-value-0.676.

Conclusion:

CCE had a better detection rate for colorectal cancer and polyp than the CTC, but this was not statistically significant. Therefore, this study failed to prove CCE's superiority over CTC. A careful decision can be made in current COVID-19 pandemic since its advantage of zero aerosolisation. Researchers should focus on innovation in techniques and simultaneous high-quality studies to evaluate them.
