ABSTRACT
Background and study aims Endoscopic submucosal dissection (ESD) for colorectal neoplasms remains challenging because of technical issues imposed by the complex anatomical features of the large intestine. We evaluated the feasibility, and the short- and long-term clinical outcomes of ESD for early colorectal neoplasms performed using the Stag-beetle Knife Jr. (SB Knife Jr.) Patients and methods We retrospectively assessed 228 patients who underwent ESD for 247 colorectal lesions with the SB Knife Jr. Clinicopathological characteristics of the neoplasms, complications, and various short- and long-term outcomes were evaluated. Results Mean tumor size was 34.3âmm and median procedure time was 76 minutes. The SB Knife Jr. achieved 98.4â% en bloc resection, 93.9â% complete resection, and 85.4â% curative resection. No perforations occurred during the procedure, and a delayed bleeding rate of 2.4â% was observed. Long-term outcomes were favorable with no distant recurrence, 1.1â% local recurrence, a 5-year overall survival rate of 94.1â% and 5-year tumor-specific survival rate of 98.6â% in patients with cancer. Conclusions ESD using the SB Knife Jr. is technically efficient and safe in treating early colorectal neoplasms and is associated with favorable short- and long-term outcomes.
