Laparoscopic or keyhole surgery is often preferred (due to less early post surgery pain, usually less scarring and less wound related issues) although open surgery can provide better outcomes for you in certain circumstances and should be considered by your surgeon. Every circumstance is different and indications are generally relative and not absolute. Groin hernias are well suited to keyhole surgery. For small to medium abdominal wall hernias from previous surgery, keyhole surgery is often a good option. Open surgery is often used for large abdominal hernias where the muscles need to be released to allow them to be stitched together. A skilled hernia surgeon should understand these issues and specifically assess your individual situation and discuss the risks and benefits of each.
