Abstract: Introduction This study aimed to evaluate the short- and long-term outcomes of single-incision laparoscopic colectomy (SILC) for right-sided colon cancer (CC) using a craniocaudal approach. Patients and Methods The data of patients who underwent SILC for right-sided CC at our hospital between January 2013 and December 2022 were retrospectively collected. Surgery was performed using a craniocaudal approach. Short- and long-term operative outcomes were analysed. Results In total, 269 patients (127 men, 142 women; median age 74 years) underwent SILC for right-sided CC. The cases included ileocaecal resection (n = 138) and right hemicolectomy (n = 131). The median operative time was 154 min, and the median operative blood loss was 0 ml. Twenty-seven cases (10.0%) required an additional laparoscopic trocar, and 9 (3.3%) were converted to open surgery. The Clavien–Dindo classification Grade III post-operative complications were detected in 7 (2.6%) cases. SILC was performed by 25 surgeons, including inexperienced surgeons, with a median age of 34 years. The 5-year cancer-specific survival (CSS) was 96.1% (95% confidence interval [CI] 91.3%–98.2%), and CSS per pathological disease stage was 100% for Stages 0–I and II and 86.2% (95% CI 71.3%–93.7%) for Stage III. The 5-year recurrence-free survival (RFS) was 90.6% (95% CI 85.7%–93.9%), and RFS per pathological disease stage was 100% for Stage 0–I, 91.7% (95% CI 80.5%–96.6%) for Stage II and 76.1% (95% CI 63.0%–85.1%) for Stage III. Conclusions SILC for right-sided CC can be safely performed with a craniocaudal approach, with reasonable short- and long-term outcomes.
