Background  The aim of this study is to evaluate the safety and efficacy of bursectomy of D2 gastrectomy in terms of postoperative complications and short-term survival outcomes.    Methods  From January 2012 to December 2013, data of 406 gastric cancer patients with advanced tumor stages and who underwent D2 radical gastrectomy and were grouped according to whether bursectomy was performed or not in West China Hospital, Sichuan University, were analyzed.    Results  Finally, 159 patients were in bursectomy group and 247 patients in non-bursectomy group. Surgical duration was 260.1 ± 43.4 min in the bursectomy group, compared to 227.9 ± 48.6 min in the non-bursectomy group ( p  < 0.001). The intraoperative blood loss was comparable between the bursectomy group and the non-bursectomy group (198.9 ± 63.5 vs. 201.1 ± 53.7 ml,  p  = 0.729). Postoperative morbidity rate showed no significant difference between the two groups, which were 23.3 % in the bursectomy group and 17.8 % in the non-bursectomy group,  p  = 0.179. The overall survival outcomes of patients were compared between the two groups of all patients ( p  = 0.055): patients who underwent distal gastrectomy ( p  = 0.129) and total gastrectomy ( p  = 0.016) and pT2-3 stage patients ( p  = 0.117) and pT4a stage patients ( p  = 0.128). The multivariate survival analysis identified that bursectomy or not, pT stage and pN stage were independent prognostic risk factors for the overall survival.    Conclusions  The bursectomy might increase the surgical duration when the D2 gastrectomy was done. Experienced surgeons can perform it safely. However, for the survival benefits of bursectomy, long-term, large sample sized, and high-quality randomized controlled trials are expected.
