Objective(s) <p>The Cerfolio-based technique is widely used for robotic pulmonary resection; however, multiple intercostal ports, particularly a posterior dorsal port, may increase invasiveness. We developed a modified Cerfolio technique (ModC) that integrates the retraction arm into the utility incision to reduce posterior intercostal ports while preserving independent four-arm manipulation.</p> Methods <p>We retrospectively reviewed 72 consecutive robotic pulmonary resections at a single institution (April 2024–November 2025): conventional Cerfolio-based approach (C group, <i>n</i> = 41) or ModC (<i>n</i> = 31; introduced April 2025). Both approaches used four robotic arms, a 30° down scope, and no CO₂ insufflation. Console time, operative time, estimated blood loss, and perioperative complications were compared.</p> Results <p>The distribution of lobectomy and segmentectomy was similar between groups (<i>p</i> = 0.635). Median console time was 134&#xa0;min in the C group and 121&#xa0;min in the ModC group (<i>p</i> = 0.096). Median operative time was 175 versus 156&#xa0;min (<i>p</i> = 0.051), and median blood loss was 5 versus 3 mL (<i>p</i> = 0.172). Major complications (Clavien–Dindo grade ≥ III) occurred in 3 patients (7.3%) in the C group and 1 (3.2%) in the ModC group (<i>p</i> = 0.629). No reoperation, readmission within 30 days, or 30-day mortality occurred.</p> Conclusions <p>ModC, a minimal modification of a Cerfolio-based workflow, can be introduced smoothly without compromising short-term outcomes.</p>
