Iatrogenic kwashiorkor after distal gastric bypass surgery: the consequences of receiving multinational treatment.

Protein-calorie malnutrition or kwashiorkor is extremely rare after gastric bypass surgery. We report a case of a woman referred to a weight management clinic in the United Kingdom who developed bilateral leg oedema 2 years after gastric bypass surgery in Tunisia. Her serum albumin concentration was 24 g/l, and her body mass index was 16.2 kg/m(2). A review of the postoperative report of her bariatric surgery revealed that she had undergone a distal bypass with anastomosis of the intestine at 1 m proximal to the ileocaecal valve. She required gastrostomy feeding for 6 months before undergoing revisional surgery to a proximal Roux-en-Y gastric bypass in order to restore healthy weight. We recommend that if patients are having their bariatric surgery outside of their country of residence, they should always obtain a copy of the operative notes so that these are readily available if complications arise.
