Complete splenic flexure mobilization is a critical step in left-sided colorectal resections. Surgeons use three approaches-anterior, medial, and lateral-to divide peritoneal ligaments connecting the left colon. The decision to perform mobilization varies, with minimal impact on post-operative outcomes but longer surgery times and rare complications. Pancreatic injury risk is low, though other structures, like arteries and the duodenum, may be at risk. Our video outlines the medial trans-mesocolic approach, with the patient positioned in lithotomy. We expose the duodenal-jejunal flexure, ligate the inferior mesenteric vein, and perform medial to lateral dissection, completing splenic flexure mobilization. This video vignette outlines how to perform this technique for left sided colorectal resections.
