Depiction illustrating the meso-fascial (A) and retro-fascial (B) separation performed in the medial to lateral approach for laparoscopic right meso-colectomy. In Meso-fascial separation (A), the plane of dissection lies between the inferior leaf of the mesocolon and the underlying Toldt’s fascia (schematically exaggerated for descriptive purpose), separating both components of the meso-fascial interface. In Retro-fascial separation (B), the plane of dissection lies between the Toldt’s fascia and the posterior parietal peritoneum covering the retroperitoneum, separating both components of the retro-fascial interface. Both dissections end with colo-fascial separation.
