Background: Gastric partitioning is a surgical procedure for the treatment of morbid obesity that may engender neurological complications, such as Wernicke encephalopathy and polyneuropathy.
Setting: A specialist hospital.
Patient: A 36-year-old woman developed Wernicke-Korsakoff encephalopathy and polyneuropathy 3 months after gastroplasty for morbid obesity. A magnetic resonance scan documented the diagnosis, and a clear improvement occurred after parenteral thiamine treatment. In our patient and in previously described cases of the literature, postsurgical vomiting is a constant finding that seems to be the precipitating factor of neurological complications of gastric partitioning.
Conclusion: Persistent vomiting after gastroplasty for morbid obesity should be considered an alarming symptom to treat immediately with appropriate measures.
