Background:
Peritoneal carcinomatosis of gastric origin is a frequent event with poor survival. A new promising approach is the association of the Cytoreductive Surgery (CRS) with the Hyperthermic Intraperitoneal Chemotherapy (HIPEC), which yet is characterized by high morbidity and mortality. We report, to our knowledge, the first case of Wernicke Encephalopathy (WE) complicating CRS plus HIPEC. WE, caused by a deficiency of thiamine, is characterized by ataxia, ocular motor cranial neuropathies and changes in consciousness.
Methods:
A patient affected by gastric cancer with peritoneal seeding, submitted to CRS plus HIPEC, in 4th post-operative day had manifested the appearance of flapping tremors, with positive manoeuvre of Mingazzini, impaired vision and mental confusion. The brain Magnetic Resonance Imaging (MRI) confirmed the clinical suspicion of WE. Even though the appropriate therapy was promptly applied, the patient died in 10th post-operative day.
Conclusion:
WE is an uncommon neurological disorder. Only 16% of these patients inadequately treated recover fully, with a mortality rate of 10-20%. We consider useful to report this case, because it is the first time that WE is correlated to CRS plus HIPEC.
