Conversion to open in robotic redo ileocolonic resection

What is known

• In the robotic redo vs robotic primary comparison, redo had significantly higher conversion to open (16.7% vs 2.5%, p=0.04), with no difference in length of stay or 30-day morbidity and no mortality or leaks. ¹
• Authors note robotic redo conversion rates, though higher than primary, appear lower than previously published laparoscopic figures. ¹
• A separate cohort found robotic redo ICR had a lower conversion rate than laparoscopic redo ICR (4.2% vs 23.8%, p=0.046). ²

What is unknown / caveats

• Both are single-center retrospective cohorts with small numbers
• The 4.2% robotic redo figure comes from a robotic-vs-laparoscopic study, not a robotic redo-vs-primary comparison
• The two robotic redo conversion figures (16.7% vs 4.2%) come from different institutional series and are not directly comparable.
