MIS vs open redo ileocolic resection

What is known

• A high-volume referral center describes MIS as first-line for ileocolic CD resection, safe and feasible even for penetrating disease or redo surgery. ¹
• In that series only 14% of resections were open, and open cases were driven by severe penetrating disease (58%), adhesions, and clustering of multiple indications. ¹
• Utilization of the laparoscopic approach for ileocolic resection rose over the last decade and several studies report reduced major and minor complications versus open. ²
• Robotic and laparoscopic platforms have both been applied specifically to redo ileocolonic resection for recurrent disease. ³

What is unknown / caveats

• Evidence is retrospective single-center cohorts and trend data, not randomized comparisons specific to the redo setting
• Conversion to open occurs and is not quantified for the redo population here
• The retrieved excerpts do not report head-to-head recurrence, leak, or long-term outcomes isolating redo MIS versus redo open.
