Anatomical observation of complete mesocolic excision during laparoscopic right hemicolectomy / 局解手术学杂志

ABSTRACT

Objective To explore regional anatomical features of fascia and spaces related to complete mesocolic excision (CME)dur-ing laparoscopic right hemicolectomy.Methods Observe and describe the regional anatomical features of related mesenterium,fascia and spaces through autopsy and somatoscopy.Results Superior mesenteric vein is the anatomic landmark in CME with medial access for laparo-scopic right hemicolectomy.Right mesocolon and ileal mesentery are the main mesenterium,and the fascia contains the prerenal fascia and the pancreatic fascia.The right retrocolic space and the colon transversum space are two important anatomical spaces,and their fusion fascia space served as a natural surgical plane.Conclusion There is a natural surgical plane which made of mesenterium,fascia and spaces be-tween mesocolon and prerenal fascia in CME during laparoscopic right hemicolectomy,and the surgery is feasible.
