The use of ultrasound in central vascular ligation during laparoscopic right-sided colon cancer surgery: technical notes

Usefulness of intraoperative ultrasound examination for laparoscopic right-side colon cancer surgery: a propensity score-matched study

“…IUS is mainly used in liver surgery to identify the tumor location and distance from the main vessels 9 and it is also applied for the detection of liver metastases in colorectal surgery 10 . Sadakari et al previously reported the technical pitfall of IUS for colorectal surgery to identify the mesenteric artery 8 , 11 ; however, its usefulness was not evaluated by a statistical analysis. This is the first report to analyze the effectiveness of IUS for RSCC.…”

“…The surgical procedure for RSCC was divided into four steps, as previously reported 8 . (1) the cranial approach (release of the bursa omentalis, dissection and mobilization of the lateral attachments and hepatic flexure); (2) the retroperitoneal approach (mobilization of the cecum and ascending colon from the retroperitoneum); (3) the medial approach (dissection of the main vessels and regional lymph nodes); and (4) specimen extraction and anastomosis.…”

“…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.…”
