Abstract

Objectives: Colonic self-expandable metallic stents (SEMSs) are widely used for preoperative decompression in obstructive colorectal cancer (CRC) patients undergoing total colonoscopy (TCS). However, the factors influencing the success of TCS and the risk of perforation remain unclear. This study aimed to identify key determinants of successful TCS after SEMS placement.
