Objective:To explore the safety and feasibility of"page-turning"laparoscopic left hemicolectomy.Methods:The clinical data of 18 patients who underwent"page-turning"laparoscopic left hemicolectomy from Jan.2023 to Nov.2023 were retrospec-tively analyzed,including the left hemicolon separation time,intraoperative blood loss,time of postoperative feeding,postoperative hospi-tal stay,tumor size,number of lymph nodes harvested,postoperative complications,postoperative pathological typing,the stage of the tumor and other relevant indicators.Results:All the 18 operations were successfully completed without conversion to open surgery.The mean intraoperative separation time of left hemicolon was(66.7±3.4)min,and intraoperative blood loss ranged from 10 to 100 mL,with the median blood loss of 50 mL.All patients took liquid diet on the first day after operation.The postoperative hospital stay ranged from 8 to 12 d,with a median of 8 d.One patient had incision infection,two patients had pneumonia,one patient had pneumonia with fe-ver,and one patient had poor healing of lower abdominal incision.All patients recovered after conservative treatment without anastomotic leakage or hemorrhage.There was no death during perioperative period.The pathological results of all patients were adenocarcinoma.The mean number of harvested lymph node was(21.0±1.5),and the maximum diameter of the tumor ranged from 3 to 17 cm,with the me-dian of 5.25 cm.The tumor stages included stage Ⅱ A in 2 patients,stage Ⅱ B in 7 patients,stage Ⅲ B in 7 patients,and stage ⅢC in 2 patients.Conclusions:"Page-turning"laparoscopic left hemicolectomy is safe and feasible with clear steps,easy to perform and learn,which is more favorable to beginners.
