Learning curves in robotic and laparoscopic colorectal surgery: a systematic review.

In 30 seconds

This systematic review evaluated learning curves in laparoscopic and robotic colorectal surgery, analyzing 114 studies with 167 learning-curve analyses. It found that operative-time plateaus occurred after 38 colonic and 56 rectal procedures. The study highlights the need for standardized reporting in learning-curve assessments.

Key findings

• Operative-time plateaus were identified after 38 colonic and 56 rectal procedures.
• Robotic surgery showed numerically lower competency thresholds for colonic resections (24 cases) compared to laparoscopic (30 cases).
• 66.4% of analyses used CUSUM or risk-adjusted CUSUM for learning-curve assessment.

Why it matters

Understanding learning curves in minimally invasive surgery is crucial for training and improving surgical outcomes. Standardized assessments can enhance comparability and guide future training protocols.
