Neurologic complications after gastric restriction surgery for morbid obesity

Abstract

We report the occurrence of neurologic complications in 23 patients who underwent gastric restriction surgery for the treatment of morbid obesity. Complications occurred 3 to 20 months after surgery. All the patients had had protracted vomiting for the first 3 months after the operation. The following syndromes were found: chronic or subacute symmetric polyneuropathy (12 patients), acute severe polyneuropathy (1 patient), burning feet syndrome (2 patients), meralgia paresthetica (3 patients), myotonic syndrome (1 patient), posterolateral myelopathy (2 patients), and Wernicke-Korsakoff encephalopathy (2 patients). The patients suffering from burning feet syndrome and those with Wernicke-Korsakoff encephalopathy showed a clear improvement after parenteral thiamine treatment. As to the rest of the patients, the occurrence of the complications seems to be linked to nutritional causes, although no such deficiencies were detected.

An Entity After Bariatric Surgery: Wernicke’s Encephalopathy

“…Bundan başka gastrointestinal cerrahi, kemoterapi, sistemik enfeksiyonlar, diyetteki yetmezlikler ve aşırı kusma gibi sekonder nedenler tiamin eksikliğine yol açar (6,9). Bariatrik cerrahi sonrası belirgin hale gelen nörolojik komplikasyonlar 3-20. aylarda olup, özellikle uzun süre kusması olan hastalarda daha sık görülür (10). Uzun süre bulantı, kusma yakınması olan hastamızın hemogram, biyokimya, troid fonksiyon testleri, folik asit ve B12 düzeyleri normal olmakla birlikte tiamin hastanemizde bakılamadığı için başka bir merkeze gönderildi.…”

Bariatrik Cerrahi Sonrası Gelişen Nütrisyonel Polinöropati: Alışılmış Bir Klinikle Ortaya Çıkan Nadir Bir Olgu

“…The Swedish Obese Subjects study (2) clearly showed that weight loss following surgery sustained 10 years post-surgery, whereas non-surgical treatment modalities did not result in long-term weight loss. Despite high percentages of weight loss, bariatric surgeries have been shown to result in many adverse events including neuropathies (3,4).…”
