Repair of an abdominal hernia with an incision directly over the hernia. This procedure can be used to repair inguinal, femoral, umbilical, epigastric, spigelian or incisional hernias.
A hernia is due to a weakness in the abdominal wall resulting in intra-abdominal contents protruding through and forming a lump. In the groin, this is commonly due to a weakness in the inguinal or femoral region. Other common sites include the umbilicus or epigastric region. Following a previous abdominal operation, people may develop an incisional hernia. The surgery involves reducing the hernia and reinforcing the area with mesh using an incision directly over the hernia.
Surgery is the only way to fix a hernia. Initially, the hernia may not be very symptomatic causing a bulge in the area, with time this can enlarge and cause more discomfort. The contents of the hernia may become obstructed or have impaired blood supply resulting in a surgical emergency. An elective operation to fix the hernia removes this risk.
You will have a general anaesthetic. An incision is made directly over the hernia. The hernia sac and its contents are returned to the abdomen where they belong. Mesh is placed to reinforce the weakened area to reduce the risk of recurrence. The skin is closed with dissolvable sutures. A waterproof dressing is placed.
Bleeding. Infection. Recurrence of hernia. Injury to intra-abdominal organs (rare). Chronic pain.
You will be admitted on the day of surgery. You cannot have anything to eat or drink for at least 6 hours before the operation. If required, part of your abdomen will be shaved around the site of the hernia.
You will be able to drink fluids in the recovery area, and if this is well tolerated you will be able to start solid food. You will be given pain relief regularly and should continue to use this once you have been discharged home. You will be encouraged to mobilise early as this aids recovery and can prevent some complications such as clots forming in your legs. Depending on the time of your operation and your personal circumstances you will either be admitted overnight or may be able to go home the day of your operation. You will need someone to drive you home. You should not do any heavy lifting for 6 weeks after surgery to allow the wound to heal fully and decrease the chance of a hernia developing or recurring. You will be followed up in the rooms 6 weeks postoperatively.
There has been much controversy in the media recently regarding transvaginal mesh prolapse repair and its potential associated risks of infection, erosion and chronic pain. Unfortunately, the media have portrayed the outcomes of this one gynaecological procedure to include all surgical use of mesh for hernia repair. It has caused unnecessary widespread patient stress and anxiety throughout New Zealand. The use of mesh in General Surgery to repair hernias of the groin or the abdominal wall is well established internationally and is considered the procedure of choice.
For ventral hernias with fascial defects greater than 2cm in diameter, mesh must be used to reinforce the tissue repair. If not, the hernia recurrence rate without mesh is unacceptably high. For groin hernia repair most surgeons worldwide use mesh for the repair. The use of mesh for abdominal and groin hernia repair is safe. Chronic pain may occur after hernia repair in less than 10% of patients. However, it is important to remember that chronic pain after groin hernia repair is higher for patients having non-mesh repair compared to mesh repair. Mesh infection after abdominal hernia repair is uncommon, less than 1 %. For laparoscopic inguinal hernia repair it is even lower. The use of surgical mesh is an important part of the curriculum for general surgical training and NZ general surgeons have extensive experience in the use of mesh for hernia repair. The good results of mesh hernia repair in general surgery should not be bought into disrepute by categorising all mesh repairs as the same.
