Femoral nerve damage after abdominal rectopexy.
Iatrogenic femoral nerve damage has already been described after hysterectomy, but never after abdominal rectopexy. We report the occurrence of femoral nerve injury in six of twenty-four patients operated on for complete rectal prolapse (n = 21) or rectorectal intussusception (n = 3). Four patients had unilateral and two bilateral lesions. All six patients had clinical and electromyographic (EMG) assessment. EMG findings were given a score from 0 (complete denervation) to 5 (normal findings). During the immediate postoperative period all patients complained of reduced cutaneous sensation of the anterior surface of the thigh and knee, and quadriceps weakness. EMG showed complete denervation in one patient, marked denervation in three, and slight or moderate denervation in the remaining two. In five patients there was complete clinical resolution at 3 to 12 months postoperatively, while one showed an improvement only. EMG control performed in four patients showed a full recovery in three. Two patients refused this examination. We believe femoral nerve damage was caused by the large-bladed self-retaining retractors used, which directly or indirectly compressed the femoral nerve.
