“…Additionally, to complete the adequate lymph node dissection for right sided colon cancer (RSCC), a precise understanding of the anatomy of the main vessels, including the superior mesenteric artery/vein (SMA/SMV), the root of the middle colonic artery (MCA), and the ileocolic artery/vein (ICA/ICV) is needed 6,7 . The efficacy of intraoperative ultrasound (IUS) in the identification of blood vessels for RSCC surgery was reported by Sadakari et al 8 . In 2021; however, no studies to date have compared conventional surgery for RSCC to those with IUS.The aim of this study was to compare the intraoperative and short-term outcomes of a propensity-matched cohort undergoing CME with CVL with or without IUS by laparoscopic surgery for RSCC.…”
