The surgical treatment of an inguinal hernia (unilateral or bilateral) using the TAPP technique offers the following differences compared to the open Lichtenstein technique in adults:
- slightly lower recurrence rates
- usually a somewhat longer operation time
- probably similar postoperative pain, but slightly less frequent chronic pain
- faster recovery
- usually higher hospital costs, but probably lower overall economic costs
Compared to the Shouldice operation, the following effects have been demonstrated:
- slightly fewer hernia recurrences
- usually a somewhat longer operation time
- slightly less postoperative pain
- faster recovery
- slightly fewer nerve injuries and chronic pain
Compared to the total extraperitoneal technique (TEP), the TAPP allows according to current data:
- slightly shorter operation times
- similar recurrence rates and pain intensities
Regarding mesh fixation with staples compared to no fixation, a study in TAPP found:
- similar recurrence rates
- similar rates of chronic pain
