手术后的英文表达是 "post-surgery"。

来源:"post-" 是英文前缀,意思是 "在……之后"。例如,"post-mortem" 意思是 "死后"。"Surgery" 是英文中手术的意思。

一些英文例句和中文翻译如下:

The patient is still recovering from post-surgery. (病人仍在手术后康复中。)
The doctor gave me some post-surgery instructions. (医生给了我一些手术后的指示。)
I have a follow-up appointment with the doctor next week to check on my post-surgery progress. (下周我有一个随访预约,检查我的手术后进展。)
