摘　　要：BACKGROUND Superior mesenteric artery syndrome(SMAS)is a rare condition causing functional obstruction of the third portion of the duodenum.Postoperative SMAS following laparoscopic-assisted radical right hemicolectomy is even less prevalent and can often be unrecognized by radiologists and clinicians.AIM To analyze the clinical features,risk factors,and prevention of SMAS after laparoscopic-assisted radical right hemicolectomy.METHODS We retrospectively analyzed clinical data of 256 patients undergoing laparoscopicassisted radical right hemicolectomy in the Affiliated Hospital of Southwest Medical University from January 2019 to May 2022.The occurrence of SMAS and its countermeasures were evaluated.Among the 256 patients,SMAS was confirmed in six patients(2.3%)by postoperative clinical presentation and imaging features.All six patients were examined by enhanced computed tomography(CT)before and after surgery.Patients who developed SMAS after surgery were used as the experimental group.A simple random sampling method was used to select 20 patients who underwent surgery at the same time but did not develop SMAS and received preoperative abdominal enhanced CT as the control group.The angle and distance between the superior mesenteric artery and abdominal aorta were measured before and after surgery in the experimental group and before surgery in the control group.The preoperative body mass index(BMI)of the experimental group and the control group was calculated.The type of lymphadenectomy and surgical approach in the experimental and control groups were recorded.The differences in angle and distance were compared preoperatively and postoperatively in the experimental group compared.The differences in angle,distance,BMI,type of lymphadenectomy and surgical approach between the experimental and control groups were compared,and the diagnostic efficacy of the significant parameters was assessed using receiver operating characteristic curves.RESULTS In the experimental group,the aortomesenteric angle and distance after
