Responsiveness of life-threatening refractory emesis to gabapentin—scopolamine therapy following posterior fossa surgery

Abstract

Craniotomy-associated chronic emesis can be refractory to currently approved antiemetic therapy. The authors describe a man who suffered 4 weeks of severe refractory emesis, failure to thrive, and a 40-lb weight loss after he underwent resection of a posterior fossa cholesteatoma. The patient experienced complete resolution of emesis and anorexia in response to combined gabapentin-scopolamine therapy. This case provides anecdotal evidence for the use of gabapentin-scopolamine therapy in patients with chronic, refractory nausea and emesis, particularly following posterior fossa surgery, during which medullary nausea and emesis centers may be affected.
