Bleeding and infection rates are very low. Occasionally there can be bruising in the inguinal region.
Recurrence rates for the Laparoscopic inguinal hernia is approximately 1%, this is similar to the traditional Open inguinal hernia repair.
Conversion to an Open Inguinal hernia (i.e. larger scar) repair occurs in less than 1%.
Post operative chronic pain is less with laparoscopic inguinal hernia repair. This is due to the position of the mesh away from the nerves, and thus less direct irritation of the nerves. Chronic pain can occur following the laparoscopic inguinal hernia repair. This is thought to be due to on-going nerve stimulation or preoperative tears in the surrounding ligaments. Tacking devices are no longer used in the laparoscopic repair.
Recently there has been some discussion into the validity of mesh. This was due to the use of mesh in repair of the pelvic floor (not inguinal hernias). Mesh placed incorrectly can cause problems.
Mesh is indicated in inguinal hernia repairs and has been used successfully for over 30 years. The NZ General Surgical Association recently released a statement affirming the above.
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.
The good results of mesh hernia repair in general surgery should not be bought into disrepute by categorising all mesh repairs as the same.
