Abstract：Objective: To evaluate the technical feasibility, safety, and clinical efficacy of the technique of transorally inserted anvil delivery system (orVil) for totally laparoscopic gastrectomy. Methods: From January 2014 to September 2014, 45 gastric cancer patients underwent D2 lymph node dissection. of these, 20 patients underwent transoral orVil EEA stapler for totally laparoscopic gastrectomy (orVil group), while 25 patients underwent conventional open gastrectomy (og group). The recovery and complication rate were compared between two groups. Results: Transoral orVil EEA stapler for totally laparoscopic gastrectomy was successfully carried out in all the patients except for 1 case who was convened to open surgery. The operation time, the mean number of removal lymph node and number of patients needed blood transfusion were not significantly between two groups. However, compared to og group, the mean blood loss were less, and first flatus time, time to resume soft diet and postoperative hospital stay were shorter in OrVil group (all P<0.05). The postoperative morbidity in orVil group and og group were 10% and 20%, respectively (P>0.05). Conclusion: OrVil is a safe and feasible procedure for totally laparoscopic Radical gastrectomy and provides satisfactory short-term efficacy.
