Application of transoral OrVil EEA stapler (OrVil) for laparoscopic radical gastrectomy / 中华普通外科杂志

ABSTRACT

Objective To evaluate the safety and efficacy of the technique of transoral Orvil EEA stapler (OrVil) for laparoscopic gastrectomy of gastric cancer in our hospital.Methods Between Sep 2012 and Aug 2013,73 patients at our department underwent open (n =36) or laparoscopic (being reconstructed by OrVil,n =37) gastrectomy.Early surgical outcomes of the two groups were compared to assess the effectiveness,security and postoperative complications of OrVil procedure.Results The two groups had similar mean numbers of dissected lymph nodes (29 ± 10 vs.31 ± 14,t =-0.697,P =0.488),lengths of postoperative hospital stay (14 ± 5 vs.12 ± 3 d,t =1.933,P =0.057) and postoperative complications (11 vs.11,P =0.939).Intraoperative blood loss was significantly less (189 ± 79 vs.343 ± 90 ml,t =-7.782,P =0.000) and time to first flatus significantly shorter (2.9 ±0.5 vs.3.5 ±0.6 d,t =-4.714,P =0.000) with the use of OrVil.Operation time of laparoscopic group was significantly longer than that of open group (266 ± 97 vs.204 ± 39 min,t =3.607,P =0.001).There was one each anastomotic leakage in both groups.Conclusions With the suitable approach and skillful technique,OrVil is a technically safe and feasible surgical procedure for the treatment of gastric cancer.
