Carcinoid syndrome.

Carcinoid tumors stimulate the release of specific hormones that lead to flushing, diarrhea, and bronchospasm. Serotonin is the most significant of these substances. Recently, a somatostatin analogue as well as the longer acting octreotide have been used to inhibit tumor secretions and reduce their untoward actions. This is a case report in which somatostatin was used perioperatively for removal of carcinoid tumors with an uneventful course.
