Peroneal palsy after bariatric surgery: is nerve decompresion always necessary?

Abstract

We present two patients who underwent successful bariatric surgery and developed peroneal nerve palsy six months after the procedure. This is an unusual complication which determines a significant functional limitation, mainly because of foot drop, and its presence may be a hallmark of excessive and rapid weight loss. We discuss possible pathogenic mechanisms and therapeutic options, and we emphasize the important role of an adequate nutritional management, in order to avoid the need for a surgical nerve decompression.
