title: Digestive endoscopy and portal hypertension. North Italian Endoscopic Club.
abstract: Improved knowledge of pathophysiology of portal hypertension and technological progress have contributed to development of new endoscopic techniques and pharmacological approaches to treatment of this condition. To put the role of endoscopy in the right perspective, it is important to consider that liver transplantation has greatly modified prognosis of cirrhosis. Because of the increase of indications for transplantation, these complications are no longer regarded as the last, but rather as an intermediate stage before a possible transplantation. We have reviewed some pathophysiologic, diagnostic and therapeutic aspects on portal hypertension, especially the role of endoscopy in diagnosis, natural history and therapeutic options for complications of cirrhosis. In addition to sclerotherapy, new endoscopic methods have been developed, with a low complication rate and possibility of being applied for treatment of gastric varices, i.e. injection of tissue adhesives and rubber band ligation. Besides oesophageal varices, gastric varices and portal hypertensive gastropathy (and portal colopathy) are important findings in cirrhosis. Further information is needed on natural history and treatment of these conditions. Digestive haemorrhage is the most important consequence of portal hypertension, so treatment should be aimed at controlling acute bleeding, rebleeding and, more important, at preventing first haemorrhagic episode. Good results will probably be obtained using a combination of drugs, a combination of endoscopic methods or a combination of both. All will need evaluation in randomised, controlled trials. These considerations renew interest in strategies for diagnosis and treatment of portal hypertension and a multidisciplinary approach may be necessary, involving gastroenterologists, endoscopists, interventionist radiologists and surgeons, ideally in a departmental environment.
