Objective:To investigate the feasibility and application value of dissection and complete resection of the right gas-troepiploic mesentery in laparoscopic radical gastrectomy.Methods:The clinical data of 35 cases of laparoscopic radical gastrectomy(based on membrane anatomy)were analyzed retrospectively.Among them,19 patients with gastric cancer underwent laparoscopic radi-cal distal gastrectomy,and 16 patients with gastric cancer underwent laparoscopic radical total gastrectomy.The dissection time,intra-operative blood loss,the number of harvested lymph nodes of the rightgastroepiploic mesentery,postoperative complications and postope-rative recovery were recorded.Results:All 35 patients successfully underwent laparoscopic radical gastrectomy.The time of dissecting the right gastroepiploic mesentery was 14-25 min,with an average of(17.1±2.1)min.The blood loss from dissecting the right gastro-epiploic mesentery was 2-20 mL,with an average of(5.0±2.7)mL.The number of lymph nodes at right gastroepiploic mesentery was 3-8,with an average of(5.2±2.1).Postoperative anastomotic bleeding occurred in 1 case,incision infection occurred in 1 case,pulmo-nary infection occurred in 1 case,all were cured by conservative treatment,and there was no operative death.Conclusions:With a deep understanding of membrane anatomy,relatively fixed surgical protocol and proficient operative techniques,dissection and complete resection of the right gastroepiploic mesentery can be performed in laparoscopic radical gastrectomy.
