Thin‐Adipose Compartment at the Colonic Mesentery–Perirenal Fat Interface: Histological and Three‐Dimensional Morphological Studies

The thin-adipose compartment represents a structurally organized anatomical unit rather than amorphous filler. Its consistent continuity and integration with adjacent structures support a compartment-based framework of intra-abdominal anatomy, which has potential relevance for understanding surgical anatomy.
