Outcomes of Knife-Assisted Full-Thickness Resection for Rectal Lesions: A Multicenter Study

Brief summary (registry, in English)

This study looks at the results of a new technique called knife-assisted full-thickness resection (kFTR) for removing rectal lesions. In kFTR, a doctor uses an electrical knife to remove a rectal growth along with the full thickness of the rectal wall. Current methods for removing early rectal tumors each have limits depending on the size and location of the growth. This study collects data from hospitals in multiple countries to find out how well kFTR works and how safe it is. Researchers review medical records and endoscopy reports from patients who already had kFTR at participating hospitals. The main measures are whether the procedure was completed successfully, whether the growth was removed in one piece, whether the edges were cancer-free, and how often complications occurred. The study also tracks hospital stay length, need for additional surgery, cancer recurrence, and death.
