Neurological complications of bariatric surgery

OBJECTIVE To review and analyze the neurological complications from bariatric surgery in Kingdom of Saudi Arabia. METHODS This cross sectional study was carried out in King Abdulaziz Medical City, Jeddah, Kingdom of Saudi Arabia from January 2009 to December 2015. Important personal and clinical data were collected from the charts of the patients who underwent bariatric surgery. Data on follow up visit and remote complication if present, was also collected. All patients with neurological complications were reviewed in detail. The significant difference was calculated by using T-test and p-value<0.05 was considered significant. RESULTS A total of 451 patients underwent bariatric surgery, 15 cases had neurological complications (3%). Axonal polyneuropathy was the most frequent neurological complication, but cases of Wernicke syndrome, vitamin B12 deficiency, Guillain-Barre syndrome and copper deficiency were also identified. Fourteen patients (93.3%) had full recovery from the neurological signs and symptoms; one patient died. CONCLUSION Bariatric surgery is not free of potential neurological complications. Complications may affect both central and peripheral nervous system and death is a possibility. Multidisciplinary care including consultation of different teams is highly recommended.
