The Impact of Traction Assisted ESD on Procedural Time, En Bloc Resection, Curative Resection and Complication Incidence

Endoscopic polypectomy, has been proven to reduce Colorectal cancer incidence and mortality. Smaller lesions and pedunculated lesions can be removed by conventional polypectomy, Endoscopic mucosa resection (EMR). However, large sessile and flat lesions are difficult to remove En bloc with EMR, resulting in a high level of tumor recurrence. Endoscopic submucosal dissection (ESD) was developed during the 1990s in Japan to achieve En bloc resection of large neoplasms in the stomach but has in recent years also been extended into management of large (>2 cm) and technically challenging colorectal polyps. Large series on the efficacy of ESD in removing benign lesions show high En bloc resection rates resulting in low numbers of recurrences. Traction assisted ESD was developed in Japan to further improve the technique and reduce procedural time, the literature on the efficacy of traction assisted ESD is however scarce and limited to Japanese studies.

The aim in this study is to investigate the impact of this novel technique in comparison to traditional ESD on procedural time, En bloc resection rate, R0 resection rate and complication incidence.
