The probability of recurrence of inguinal hernia in middle age is under 1%. The causes of recurrence after inguinal hernia surgery are multiple, and all causes of high intra-abdominal pressure may lead to recurrence. For example, participation in heavy labor during the postoperative recovery period, long-term chronic cough, constipation, urinary difficulties, ascites and so on are all potential causes of hernia recurrence. Inadequate choice of surgery is also a major cause of recurrence. To prevent the recurrence of inguinal hernia after surgery, you should choose the appropriate surgical method. Treat the primary causes of recurrence such as chronic cough, constipation, and urination difficulties. Physical labor should also be avoided during the recovery period. With the continuous improvement of surgical methods (patch, minimally invasive) and standardized surgical operation, the recurrence rate of inguinal hernia will become lower and lower.
