OBJECTIVE: To explore regional anatomy of fasciae and spaces related to laparoscopic right hemicolectomy (LRC). METHODS: Seven cadavers and 49 patients undergoing LRC for cancer were observed. Computed tomography (CT) images of patients and healthy individuals were reviewed. RESULTS: Between ascending mesocolon and prerenal fascia (PRF), there was a right retrocolic space (RRCS), which communicated in all directions. Anterior, posterior, medial, lateral, cranial, and caudal boundaries of the RRCS were ascending mesocolon, PRF, superior mesenteric vein, peritoneal reflexion at right paracolic sulcus, inferior margin of transverse part of duodenum, and inferior margin of the mesentery root, respectively. Between transverse mesocolon and pancreas and duodenum, there was a transverse retrocolic space (TRCS), which was bounded cranially by root of transverse mesocolon. On CT images of healthy individuals, PRF was noted as slender line of middle density, continuing to transverse fascia, and the retrocolic spaces were unidentifiable. For patients with right colon cancer, PRF and right retrocolic space might be easier to be identified. CONCLUSIONS: The RRCS and the TRCS are natural surgical spaces. The PRF is natural surgical plane in LRC for cancer.
