The three surgical planes in LCME for right-sided colon cancer. When the three surgical planes are superimposed, they resemble the rungs of a ladder. a The anatomical features involved with the LCME procedure are labeled. b The three surgical planes are labeled. The tissue that appears orange represents the right anterior renal fascia plane, which includes the FSP. The tissue that appears yellow includes the fusion fascia plane of the pancreatic head and the anterior layer duodenum fascia, and this represents the SSP. The tissue that appears purple is the space plane that is separated from the posterior lobe of the transverse mesocolon and the dorsal mesogastrium fusion fascia, and it represents the TSP.
