Hernia surgery is a common minor surgery in general surgery, but how to make this minor surgery as small as possible requires work in all aspects. How to achieve the least risk: use local anesthesia, not the relatively dangerous general anesthesia or hemi-anesthesia, and do the simplest Lijinstein procedure with effective repair and try not to do other complex repair procedures. How to do the least damage: still use local anesthesia with little damage to the person and Lijinstein surgery with little damage. How to achieve the least cost: or the least costly local anesthesia under Lighenstein surgery, preferably taking the same day surgery with the lowest cost. How to do the least pain: or take on the application of local anesthetic in the surgical area of local anesthesia, not to do tracheal intubation general anesthesia or lumbar puncture lumbar anesthesia; do separation and minimal damage to the least comprehensive pain of the Lijinstein surgery.
