Cut or sustain?

I am 6'2 and around 165 lbs,18% bodyfat.

I have been bulking eating salmon,beef,chicken,eggs,broccoli,cauliflower,spinach,nuts and apples.

In 5 days I am going to have a foot surgery which is going to keep me out of gym for at least 2.5 months,I will be able to do some push ups,hammer curls and sit ups/planks. Should I cut or sustain until I get back to the gym?
