Gastric partitioning complicated by peripheral neuropathy with lumbosacral plexopathy.

Gastric bypass and partitioning are the two surgical procedures most commonly used in the treatment of morbid obesity. They are, however, not without their postoperative complications. These include acute and chronic problems such as wound infection, gastric leak, obstruction, embolism, and neurologic sequelae. Many studies have mentioned the frequent occurrence of polyneuropathy in the postgastrectomy state. This report describes a 38-year-old patient who developed an asymmetric peripheral neuropathy with lumbosacral plexus involvement following gastric bypass surgery for morbid obesity.
