Non-cirrhotic portal hypertension in inflammatory bowel disease.

With the increasing incidence and prevalence of IBD, its complications and associated morbidity also continue to rise. One of these is non-cirrhotic portal hypertension. There is an increasing need of recognizing and understanding the pathophysiology of this condition in the clinical setting of IBD, especially in long standing cases. Due to multiple potential factors, patients with IBD appear to be at a higher risk of developing portal hypertension even in the absence of liver cirrhosis. Portal hypertension is usually diagnosed when complications (such as ascites, variceal bleeding) develop, especially when patients have already experienced multiple complications of the disease. Hence, a high level of vigilance for the detection of portal hypertension at an early stage is needed. This review discusses the known epidemiology, clinical characteristics, clinical presentation, modalities of diagnosis and the potential treatments of the different forms of non-cirrhotic portal hypertension associated with IBD. The concomitant presence of portal hypertension can significantly impact the overall clinical picture and disease burden in IBD. Hence, increased awareness of this condition at an early stage might help tailor a comprehensive and individualized therapeutic plan of care for these patients.
