Abstract Laparoscopic approaches have become a standard strategy for colon cancer patients who undergo surgical treatment. Complete mesocolic excision (CME) with central vascular ligation (CVL) is the fundamental principle of radical resection of colon cancers. Splenic flexure colon cancer (SFCC) is rare, accounting for less than 4% of all colorectal cancer cases. Moreover, a laparoscopic approach for SFCC following the CME/CVL concept can be challenging because the blood supply of the splenic flexure is derived from either the middle colic artery (MCA) branching from the superior mesenteric artery, the left colic artery (LCA) branching from the inferior mesenteric artery. In addition, approximately one third of SFCC patients have an accessory MCA that can originate from the celiac trunk. Herein, we describe the technical procedure of a laparoscopic left hemicolectomy for SFCC using indocyanine green (ICG) for necessary and sufficient lymphadenectomy followed by intracorporeal anastomosis. Two injections of ICG (0.5 mg/0.2 ml × 2) into the subserosa of the proximal and distal sides of the tumor preceded the surgical procedure after pneumoperitoneum. Near infrared images obtained throughout the laparoscopic procedure helped visualize lymphatic drainage vessels and inform decision making for determining vessels requiring ligation according to the CVL concept: MCA, LCA or accessory MCA. Complete intracorporeal anastomosis following necessary and sufficient lymphadenectomy with ICG can minimize the dissecting area of the laparoscopic left hemicolectomy for SFCC patients. Intravenous ICG injection (2.5 mg) after anastomosis helps confirm blood perfusion at the anastomosis site. Four patients with SFCC underwent a laparoscopic colectomy under ICG navigation in 2019 at our institute. The median operative time was 237 min, the median estimated blood loss was 0 ml, and the median number of dissected lymph nodes was 13. No patients experienced postoperative complications. In conclusion, laparoscopic left hemicolectomy with ICG navigation and intracorporeal anastomosis for SFCC patients may be a feasible option for the radical resection of colon cancer.
