The most common sequelae after pediatric hernia surgery and the most worrying for parents is the recurrence of hernia after surgery. Both open surgery and minimally invasive surgery involve high ligation of the unclosed inner ring opening, which can recur if the ligature wire breaks or falls off prematurely, and the sequelae include local scrotal swelling, fluid accumulation and even hematoma formation, which usually takes 0.5-1 month or even longer to absorb. In addition, let the child eat a light diet, avoid eating undigested food, keep the bowels open, reduce strenuous exercise and avoid violent coughing, all of which are actions that increase abdominal pressure and can cause postoperative hernia recurrence. The postoperative hernia wound should be kept out of water as much as possible to avoid infection of the incision or persistent scrotal swelling that does not disappear, and the next step of treatment should be decided according to the specific situation. Generally, the vas deferens can be clearly revealed during surgery, and attention should be paid to protection, and hernia surgery will not affect fertility.
