In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Extraintestinal manifestations occurred at lower frequency in elderly-onset compared with pediatric-onset patients. In both age populations, presence of EIM at diagnosis independently increased the need for corticosteroid and immunosuppressive treatment.

A 15-month-old girl, who presented with biliary cirrhosis secondary to cystic fibrosis with refractory ascites and recurrent intestinal bleeding, underwent percutaneous transjugular intrahepatic portosystemic shunting. Immediately following the procedure the ascites disappeared and no further bleeding occurred. The stent shunt was patent on Doppler ultrasound until the 22nd day. The patient died on day 22 because of liver failure due to a low-flow syndrome with severe hepatic ischaemia, but with no recurrence of bleeding or ascites.
