The Trans-Abdominal Pre-peritoneal Repair (TAPP), is an alternative keyhole technique for inguinal hernia repair.  With this technique  a camera is inserted into the abdominal cavity. Gas is introduced, enabling the surgeon to see the hernia sac.  The hernia is repaired using a piece of mesh which is inserted behind the muscle of the abdominal wall.

The principle advantages of this technique over open surgery are:

less post operative pain, 

a quicker recovery a

a quicker return to full physical activities.  

There is no significant difference in the recovery after TEP or TAPP repair.
