Learning curve for robotic ileocolic resection

What is known

• CUSUM analysis in a case-matched robotic vs laparoscopic IBD cohort identified a proficiency inflection at case 20 for ileocecal resections (case 11 for restorative proctectomy). ¹
• Data from established robotic programs indicate experienced surgeons need ~23–30 cases to reach proficiency, versus ~74 cases for novices. ²
• The same discussion cites broader colorectal reports of proficiency at ~15–25 cases, with operative efficiency around 12 cases and complication reduction around 15. ¹

What is unknown / caveats

• Thresholds vary widely with prior laparoscopic experience and surgeon baseline
• Estimates derive from single-institution CUSUM analyses and narrative review, not multicentre standardized endpoints
• The exact case number depends on the metric used (operative time vs complications) and prior minimally-invasive experience.
