Core Tip
Core tip: This study aimed to assess the theoretical advantages of magnetic endoscopic imaging (MEI) over standard colonoscopy (SC) and to compare the efficacies of MEI and SC. The meta-analyses compared the cecal intubation rate and time, sedation dose used, abdominal pain scores and the use of ancillary maneuvers between MEI and SC. The real-time magnetic imaging system is of benefit in training and educating inexperienced endoscopists, and it improved the cecal intubation rate for both experienced and inexperienced endoscopists.
