    Abstract:
    BACKGROUND: Hepatic venous pressure gradient (HVPG) increases significantly after endoscopic therapy in patients with bleeding oesophageal varices, which may precipitate further haemorrhage. Whether vasoactive drugs can suppress these changes remains unknown. AIM: To investigate the efficacy of somatostatin when compared with octreotide in preventing the post-endoscopic increase in HVPG during acute bleeding and whether the changes affect outcome. METHODS: Thirty-three cirrhotics with bleeding varices were randomized to receive somatostatin (n = 17) or octreotide (n = 16) under double-blind conditions, soon after their admission. HVPG measurements were performed before and immediately after endoscopic treatment. RESULTS: In the somatostatin group, postendotherapy HVPG values did not change significantly when compared with pre-treatment values (18.9 vs. 17.2, P = 0.092). Conversely, in the octreotide group, HVPG increased significantly after endoscopy (18.2 vs. 20.8, P = 0.003). The probability of 6-week survival without treatment failure was significantly higher in the somatostatin group (P = 0.024). Post-endoscopic HVPG value was independently associated with 6-week failure. CONCLUSIONS: Somatostatin, but not octreotide, effectively prevents the post-endoscopic increase in HVPG, which may be associated with low probability of treatment failure.
