Although endoscopic submucosal dissection (ESD) is an accepted and established treatment for early esophageal squamous cell carcinoma (EESCC), it is technically difficult, time consuming, and less safe than endoscopic mucosal resection. To perform ESD safely and more efficiently, we proposed a new technique of esophageal ESD using an IT knife nano with the clip traction method. This study aimed to evaluate the efficacy and safety of ESD using this new technique.
We retrospectively reviewed all consecutive cases of esophageal ESD performed using an IT knife nano with the clip traction method at our hospital between March 2013 and January 2017. Therapeutic efficacy and safety were also assessed.
A total of 103 patients underwent esophageal ESD using the IT knife nano with the clip traction method. In all cases, we performed en bloc resection. Complete resection was achieved in 100 cases (97.1%). The median operating time was 40 (range 13–230) min. No cases of perforation or delayed bleeding occurred. Although two cases (2.0%) of mediastinal emphysema occurred without visible perforation at endoscopy, all were successfully managed conservatively.
The new technique of esophageal ESD using the IT knife nano with the clip traction method appears to be feasible, effective, and safe for EESCC treatment.
