Why should the treatment of hernia be standardized After Xiao Guo had a hernia repair operation in a local hospital, although the hernia was cured, one year after the operation, the wound site has been continuously painful and the foreign body feeling is serious. It greatly affected his life and work, and he had to operate again. The surgery revealed that the repair material used in the previous surgery filled the hernia ring opening, but the hard three-dimensional mass formed compressed the surrounding tissues and nerves, causing great pain. After the second surgery, the previous mesh plug was removed and the hernia was repaired with a flat piece of material, and normal work and life resumed. Currently, although surgical repair is the only scientifically effective method for the treatment of hernias, a wide variety of different mesh materials, different mesh shapes, and the use of different equipment affect the outcome of surgery and the patient’s prognosis. Standardized treatment is the guarantee of a good outcome, and the tragedy of Xiao Guo’s case is that he did not receive standardized surgical treatment. The standardized treatment must be based on evidence-based medicine. The so-called evidence-based medicine is to obtain the most reliable basis for the effectiveness and safety of a certain therapy for a specific patient’s problem and respect the patient’s choice, and then make clinical decisions after comprehensive evaluation to guide rational treatment.
