OBJECTIVES: We tested whether complementary use of the somatostatin analogue pasireotide would augment efficacy of aspiration sclerotherapy of hepatic cysts. METHODS: We conducted a double-blind, placebo-controlled trial in patients who underwent aspiration sclerotherapy of a large (>5 cm) symptomatic hepatic cyst. Patients were randomized to either intramuscular injections of pasireotide 60 mg long-acting release (n = 17) or placebo (sodium chloride 0.9 %, n = 17). Injections were administered 2 weeks before and 2 weeks after aspiration sclerotherapy. The primary endpoint was proportional cyst diameter reduction (%) from baseline to 6 weeks. Secondary outcomes included long-term cyst reduction at 26 weeks, patient-reported outcomes including the polycystic liver disease-questionnaire (PLD-Q) and safety. RESULTS: Thirty-four patients (32 females; 53.6 +/- 7.8 years) were randomized between pasireotide or placebo. Pasireotide did not improve efficacy of aspiration sclerotherapy at 6 weeks compared to controls (23.6 % [IQR 12.6-30.0] vs. 21.8 % [9.6-31.8]; p = 0.96). Long-term cyst diameter reduction was similar in both groups (49.1 % [27.0-73.6] and 45.6 % [29.6-59.6]; p = 0.90). Mean PLD-Q scores improved significantly in both groups (p < 0.01) without differences between arms (p = 0.92). CONCLUSIONS: In patients with large symptomatic hepatic cysts, complementary pasireotide to aspiration sclerotherapy did not improve cyst reduction or clinical response. KEY POINTS: * Complementary pasireotide treatment does not improve efficacy of aspiration sclerotherapy. * Cyst fluid reaccumulation after aspiration sclerotherapy is a transient phenomenon. * Aspiration sclerotherapy strongly reduces symptoms and normalizes quality of life.
