[Bilateral peroneal neuropathy following bariatric surgery].

We report the case of bilateral peroneal neuropathy following massive weight loss after bariatric surgery. A few months after a gastric by-pass, the patient developed sequentially within 6 months a L2-L3 herniated disc that required surgery, a severe right peroneal nerve palsy that led to decompressive surgery and finally contralateral peroneal nerve palsy also operated. The electrophysiological analysis confirmed the clinical suspicion of peroneal nerve compression at the fibular head. Postoperative course was favorable. Literature reports peroneal nerve palsy after slimming, mostly when weight loss is fast and marked although the issue is rarely bilateral.
