Background: Total colonoscopy (TCS) after colorectal stenting for bridge to surgery (BTS) in obstructive colorectal cancer has been reported to be effective. However, the factors influencing successful TCS remain unclear.
Methods: This retrospective study analyzed 45 patients who underwent TCS after stenting for BTS between 2016 and 2023, Patients were divided into successful and unsuccessful groups.
Results: The success rate was 73.3% (33/45). Stents placed in non-flexure regions and larger expansion diameters (≥19.6 mm) were significantly associated with successful TCS (p<0.05). The optimal cutoff for stent expansion diameter was 19.6 mm, with a sensitivity of 60.6% and specificity of 83.3%, and an AUC (area under the curve) of 0.737.
Conclusion: Stenting in non-flexure areas and adequate stent expansion are key factors for successful TCS. Pre-procedural assessment of stent expansion diameter can help predict TCS success.
