Ventral hernia is formed when an organ or tissue in the abdominal cavity protrudes through a weak point or defect in the abdominal wall or pelvis toward the body surface and is one of the most common diseases in surgery. A large number of cases have been cured using open tension-free repair surgery under local anesthesia and laparoscopic hernia repair surgery. Patients are less traumatic, easily tolerated, incision is closed intradermally without removing stitches, recovery is fast, and they can eat and get out of bed in 6 hours after surgery, and they can usually be discharged in the afternoon of the first day or the morning of the second day after surgery, here is a description of the problems related to postoperative extra-abdominal hernia surgery. 1. Postoperative incision problems The incision is closed with absorbable thread intradermal suture, which does not need to be removed, and the resident doctor of our department will change the medicine for the patient once on the day of discharge. After discharge, the wound dressing can be kept for 2 to 3 days, then the wound dressing is removed and the wound does not need to be changed again and can be exposed. The wound can be exposed to water for 2 weeks after surgery, and avoid rubbing and squeezing the wound. Slight swelling, mild stinging and itching of the wound are normal. If the wound has blood spillage, severe pain or local swelling is significantly higher than the skin, you should contact the doctor or seek emergency medical treatment in time. 2. Life precautions During surgery, the patch is fixed to the ligaments and tendons by stitches, and it takes 1 to 3 months for the patch and the surrounding tissues to heal completely. Excessive movement can cause stitch tearing and patch contracture, which is an important cause of local pain, swelling and hardness after surgery, and can also lead to an increase in the recurrence rate of hernia. Early bedtime activity is recommended after surgery, but severe coughing, straining to relieve stool, and strenuous exercise should be avoided. A week’s rest is required after surgery, after which light workers (e.g., office workers) can return to work, and strenuous exercise or heavy work should not be performed for 3 months after surgery. General life and sports, including walking, jogging, driving, climbing, bicycling, sexual life, etc. will not be affected. Diet according to the usual diet, no special tonic, avoid smoking, alcohol and spicy diet. Actively prevent and control the disease of increased intra-abdominal pressure, if there is chronic cough, prostatic hyperplasia, constipation, etc. should be actively and correctly treated to reduce the chances of recurrence and prevent recurrence on the opposite side. 3, post-operative review Post-operative review is helpful for patients to understand their own disease situation in time to prevent and deal with the occurrence and development of post-operative complications. It also helps the doctor to understand the patient’s condition, surgical effect and recurrence or not, and timely statistics are beneficial to medical research work. In our hospital routine, the first review is generally required one month after surgery, and another review is required six months after surgery. 4.Common postoperative complications: (1) pain: pain is normal after open surgery, local discomfort, pain when moving, and local hard nodes are normal, most of the pain is acceptable, no medication is needed. Younger patients or more sensitive patients can take medication for pain relief in the early postoperative period. Laparoscopic surgery is a minimally invasive procedure, and postoperative pain is mild and mostly insignificant. (2) Effusion: postoperative effusion is a common condition after laparoscopic surgery, which in most cases does not require special treatment and can generally be absorbed on its own in 1 to 3 months. Open surgery may also result in effusion in patients with larger hernia sacs, and the treatment is the same as before. If the fluid accumulation is large or cannot be absorbed for a long time, it can be punctured and extracted. (3) Numbness in the operated area: It is seen in open surgery, mostly due to the damage of the surgical incision to the local dermal nerve, causing local numbness and discomfort, which usually does not affect normal life and most of them can recover in 3 months to 6 months after surgery.
