Is inguinal hernia major or miner surgery?

Lower complexity : Any surgery is a major surgery as complications can happen. Hernia surgery is outpatient and usually straightforward. Risks (during and long term) are low.

It depends if: You are the patient or the surgeon. But seriously it depends on the size of hernia, its location, your pain tolerance, and all kinds of things. And major and minor are relative terms. I tell my patients that every operation is important and for me it is the most major thing that I am doing at the time.
