QUEZADA, José L.; JIMENEZ, Julio; FLUXA, Paula  y  BUSTAMANTE, Marco. Benefit of bursectomy in gastrectomy D2 for gastric cancer. A systematic review. Rev Chil Cir [online]. 2017, vol.69, n.5, pp.382-388. ISSN 0718-4026.  http://dx.doi.org/10.1016/j.rchic.2017.05.003.

Introduction:

The surgical resection has proved to be the only curative option for Gastric Cancer, when including D2 linfadenectomy as security standard.

The benefit of extending the resection to the bursa omentalis, however, is still controversial. The published research has not yielded categorical evidence on defining the efficacy of bursectomy.

We conducted a systematic review of published randomized controlled trials (RCT), to evaluate the benefit of bursectomy in the overall survival (OS) and disease-free survival (DFS) of patients. As secondary outcome, was considered the safety of the procedure.

Methods:

A literature search was conducted in Pubmed, Cochrane library databases, Scielo, Metabuscador PUC, Epistemonikos, Tripdatabase, Sciencedirect, and Lilacs for randomized clinical trials comparing bursectomy with non-bursectomy, published before March 2016. Inclusion and exclusion criteria were established and applied.

Results:

We found three RCT corresponding to different reports of the same cohort of randomized patients. They included 210 patients (104 in the bursectomy group, and 106 in the non-bursectomy group). The bursectomy did not have a significant effect either on 5-years OS (HR: 1.4; 95%CI: 0,87-2,25), or on DFS (HR: 1.25; 95% CI: 0,80-1,97).

No statistically significant difference was observed in the rate of complications, when comparing the bursectomy group and the non-bursectomy group.

Conclusion:

Gastrectomy with bursectomy is not superior to non-bursectomy either in terms of 5 years OS or on DFS.
