Anatomical variations of the middle colic vessels. Upper row: the transverse colon in three different cases demonstrating a single, double, and absent middle colic vessel in a, b, and c, respectively. Lower row (d, e, and f): fashioning of transverse colonic flaps based on left colic vessels after ligation of middle colic vessels for the same three cases, respectively. Note: black arrows point to middle colic vessels, while the white arrows point to left colic vessels (flap pedicle)
