Gastrografin™ – Induced hyperthyroidism in patients with cystic fibrosis following lung transplantation: A case series

Distal intestinal obstruction syndrome (DIOS) is a common complication in patients with cystic fibrosis (CF) [1]. DIOS occurs in 10 to 40% of all CF-patients. The risk of developing DIOS is considered higher in the early post-transplant period due to dehydration, immobility, intake of opiates and post-operative adynamic gut [2]. Patients suffer from prolonged intestinal passage or even gastric paresis due to polymedication leading to chronic constipation long-term following lung transplant (LTX) [2].
