Refeeding syndrome in a patient with an obstructive pancreatic cancer: An emerging complication of artificial nutrition in the gastroenterology ward

Refeeding syndrome (RS) is a life-threatening condition first described in severe malnourished prisoners of the Second World War. This syndrome is defined as electrolyte and fluid shifts associated with metabolic abnormalities developed during nutritional support. RS hallmark is hypophosphatemia, but also includes hypomagnesemia, hypokalemia, vitamin deficiencies, abnormal glucose metabolism and fluid retention. Prolonged fasting is the most important risk factor and RS may be precipitated by oral, enteral or parenteral nutrition. The authors describe a case of RS in the gastroenterology ward exemplifying the importance of recognizing this underreported condition in patients with digestive pathology under nutritional therapy.
