[Surgical Outcomes and Method of Ensuring the Surgical Field in Single-Incision Laparoscopic Surgery for Right- Sided...

Single-incision laparoscopic surgery(SILS)is considered minimally invasive and is associated with high patient satisfaction due to its cosmetic appeal and the potential to reduce the number of surgeons required. We report a method for ensuring the surgical field in SILS for right-sided colon cancer, along with the surgical outcome. By effectively utilizing gravity through bed rotation and tissue traction using a triangular jaw, a good surgical field can be ensured. We verified the safety and effectiveness of SILS by comparing the surgical outcomes of 11 patients who underwent SILS and 25 patients who underwent conventional multi-port surgery(MPS)among 36 patients who underwent laparoscopic surgery for right -sided colon cancer by a single surgeon at our hospital between April 2014 and March 2025. No significant differences were observed between the 2 groups in terms of patient background and tumor factors, and both short-term surgical outcomes and long-term prognoses(5-year overall survival rate: 80.0% vs 75.0%, p=0.64)were equivalent. Owing to its ingenuity in ensuring the surgical field, SILS can be safely conducted for right-sided colon cancer without compromising radicality, similar to MPS.
