triangle of pain
An anatomical area during laparoscopic inguinal hernia repair where injury to lateral femoral cutaneous nerve may occur.
Full Definition
The triangle of pain is a critical anatomical landmark in laparoscopic inguinal hernia repair, specifically during TEP and TAPP procedures. It is bounded by the testicular vessels medially and the iliopubic tract laterally. This area contains the lateral femoral cutaneous nerve, and inadvertent tacking or stapling in this region can result in lateral femoral cutaneous nerve entrapment, causing numbness or pain in the lateral thigh.
Usage
Usage note: Specific to laparoscopic hernia repair procedures.
