Endoscopic Full-Thickness Resection of Colorectal Lesions with the New FTRD System: Single-Center Experience.
Background and Aims
Endoscopic full-thickness resection (EFTR) is an emerging technique for the treatment of various conditions for which classic endoscopic resection techniques have failed or were considered to be at high risk for perforation. The full-thickness resection device (FTRD) is an over-the-scope system which allows a single-step EFTR. The aim of our study is to describe our experience in EFTR of colorectal lesions using the FTRD.


Methods
Nine patients (10 colorectal lesions) were proposed for EFTR. Safety, R0 resection and endoscopic treatment success were evaluated.


Results
Reasons for referral included nonlifting adenomas (n = 4), nonlifting adenoma recurrence (n = 5), and submucosal lesion (n = 1). EFTR was technically successful in all patients. The mean duration of the procedure was 55 min. R0 resection was obtained in all patients. No major complications were detected. All lesions were successfully treated by the endoscopic technique and no patient was referred for surgery. In patients with available follow-up (n = 6), no recurrence was detected.


Conclusions
EFTR is a feasible, reasonable time-consuming, safe, and promising endoscopic resection technique.


Key Messages
FTRD is an additional tool for difficult-to-treat colorectal lesions.
