This video shows submesocolic medial-to-lateral laparoscopic mobilization of the splenic flexure in which embryologically-derived planes are highlighted using colorized parts in a black and white background. The concept of traction and counter-traction is used to create a tissue "bridge" to work beneath, making efficient use of both of the surgeon's hands. To our knowledge, the color-grading technique has not been previously used to edit a video of a laparoscopic procedure, thus creating a new method of teaching.
