What it really means

A surgical procedure — what many learners would call "surgery" in the medical sense. British people usually say "I'm having an operation" or informally "an op". Remember: "the surgery" usually means the doctor's office instead.

Chinese explanation
手术:外科手术在英式英语里常说"operation",口语也说"op"。注意区分:"the surgery"通常指诊所,而不是手术。

Example conversation

A:Tom下个月怎么不上班? B:他要做膝盖手术,之后要恢复几个星期。
