Aims Endoscopic submucosal dissection (ESD) is a challenging procedure for resection of
early neoplasias. Countertraction can improve access to the submucosal layer and facilitate
ESD. We aimed to evaluate the ProdiGI Traction magnet for colorectal ESD.
Methods Colorectal lesions resected with assistance of the traction magnet device were evaluated.
The primary endpoint was technical and clinical success of ESD including en bloc and
R0 resection. Secondary endpoints were complication and recurrence rates.
Results Fifteen colorectal ESD procedures (11x rectum, 3x sigmoid, 1x transverse colon) with
the Traction Magnet Device were performed. All procedures were technically feasible
and none was discountinued during implementation of the method. Attachment of the
clips to the mucosal flap and the intestinal wall, respectively, was feasible without
detachment of the clips or the magnets. En Bloc and complete resection rates were
100%, respectively. No immediate or delayed complications related to the procedure
occured, while on follow-up endoscopy at 3 months, residual/recurrent tumor was not
detected in any of the patients (n=0, 0,0%).
Conclusions The Prodigi Traction magnet can assist endosocpists and improve outcomes during colorectal
ESD.
