Earlier year of surgery did not reach statistical significance on the α = 0.050 level in univariable analysis but showed a trend towards shorter OS ( p = 0.064) and was therefore included in the multivariable analysis.

Overall complications ( p = 0.198), major surgical complications ( p = 0.832) and anastomotic leak ( p = 0.396) did not reach statistical significance as risk factors for decreased OS in univariable analysis.
