Intra-operative findings during laparoscopic low anterior resection. A At the usual site of the root of the IMA, IMA root was absent and only the colic branch of the lumbar splanchnic nerve was identified. B The ICG fluorescence-illuminated lymphatics were interrupted near where the IMA usually branches, and there was no central fluorescence-illuminated lymphatics. C We preserved the aMCA and ligated the IMA branching and the IMV on the same level, which is the upper border of the lymphadenectomy (dotted line). D All of the ICG fluorescence-illuminated lymphatics was resected. E The line of dissection of the mesentery were determined (dotted line). (IMA inferior mesenteric artery, ICG indocyanine green, aMCA accessory middle colic artery, IMV inferior mesenteric vein)
