Long-acting somatostatin analogue therapy in obscure-overt gastrointestinal bleeding in noncirrhotic portal hypertension: a case report and literature review.

We describe a case of obscure gastrointestinal bleeding in a male with noncirrhotic portal hypertension who required multiple admissions and repeated blood transfusions over a 5-month period. Upper and lower gastrointestinal endoscopy failed to establish a cause for bleeding which was eventually ascribed to universal portal hypertensive stigmata in stomach, small bowel and colon, which were not amenable to endoscopic therapy. On account of extensive venous thrombosis, neither surgical shunting nor interventional radiology was an option. Initial management with prothrombotic agents failed. Our patient was successfully stabilized on long-acting somatostatin (SMS) analogue therapy using lanreotide, resulting in avoidance of further admissions and blood transfusion and restoration of his independence and quality of life. The use of short-acting SMS analogues is recognised in acute variceal haemorrhage secondary to portal hypertension in cirrhosis, and long-acting SMS analogue therapy has been described in obscure gastrointestinal bleeding though secondary to angiodysplasia. However, the potential role of long-term SMS analogues in noncirrhotic portal hypertensive bleeding of this type has not been reported earlier. This case supports its use in this scenario in the absence of surgical options and when only palliative approaches are available.
