Reduction by Pasireotide of the Effluent Volume in High-output Enterostomy in Patients Refractory to Usual Medical Treatment

During rectal or complex digestive surgery with multiple digestive resections and anastomosis, the creation of enterostomy is a common procedure. In France, it is estimated that 20000 patients have an ileostomy and 16000 new digestive stomas are formed each year with approximately 30% of enterostomy. Enterostomy might sometimes give high-output not controlled with usual medical treatment (e.g loperamide ± codeine) and exposes the patients to important hydro-electrolytic loss leading to a risk for dehydration, electrolyte abnormalities and acute renal failure. This risk implies parenteral correction which may extend hospital stay and delay home return. Somatostatin analogues (octreotide, lanreotide and pasireotide) could reduce digestive secretions and decrease digestive peristalsis. Nevertheless, somatostatin analogues are not routinely used for the treatment of patients with high-output enterostomy and their efficacy in the indication (off-label) was only tested in small case series. Pasireotide (SOM230, SIGNIFOR®) is currently indicated for the treatment of patients with Cushing's disease for whom surgery is not an option or for whom surgery has failed. As the efficacity of pasireotide in patients with high-output enterostomy refractory to usual medical treatment associated with an oral fluid restriction has never been demonstrated before, there is a need to perform a pilot, double-blind, randomized, placebo-controlled trial evaluating its impact on reduction of the effluent volume.
