Core Tip

Core Tip: This study retrospectively analyzed 256 patients undergoing laparoscopic-assisted radical right hemicolectomy, and six patients developed superior mesenteric artery syndrome (SMAS). The preoperative and postoperative aortomesenteric angle and distance were compared in the six patients, and 20 patients without postoperative SMAS were randomly selected for comparative analysis with 6 patients developed SMAS. The results and literature review suggest possible reasons and preventative measures for SMAS after right hemicolectomy.
