In the clinic, we often encounter the situation where a patient has a “hernia” and decides to have an operation, but the hernia reappears some time after the operation, and some even have two or three operations repeatedly, but finally it recurs, which is very painful for the patient. So how can we prevent the recurrence of hernia? There are two reasons for hernia formation: 1. weakness of the hernia formation area; 2. increased pressure in the abdominal cavity. If we do not solve the problem of high intra-abdominal pressure, it will be easy to recur. Patients should pay attention to the following points: 1. Those who have a combination of prostate hypertrophy, excessive obesity, ascites, cough, constipation, etc. that can lead to increased intra-abdominal pressure before surgery should first solve these problems before considering hernia surgery. 2. Hernia surgery is divided into traditional repair and tension-free repair (patch). Tension-free hernia repair is currently a relatively good surgical procedure, but it can increase medical costs because of the need to add supplementary materials. It is recommended that friends with hernia choose the patch method as much as possible, which can significantly reduce the chance of recurrence after hernia repair. 3. In the recent post-operative period, it is recommended not to carry weight or engage in strenuous sports for three months because the wound has not healed firmly.
