Intraoperative Carcinoid Syndrome During Small-Bowel NET Surgery: Description, Prevalence and Risk Factors.

#1685

Introduction: Few studies on intraoperative carcinoid syndrome (ioCS) are available.

Aim(s): Aims were to describe, define ioCS diagnosis criteria and evaluate ioCS risk factors.

Materials and methods: We retrospectively analyzed patients operated for small-bowel (SB) NET in our ENETS excellence center (2007-2015) receiving preoperative continuous octreotide (40 or 80 µg.h-1 according to the presence of liver metastases or prior CS). ioCS was defined as highly-probable (rapid arterial blood pressure changes ≥ 40% without surgical/anesthetic reasons and regressive ≥ 20% after octreotide injection), probable (one criteria missing) or suspected (octreotide injection for manifestation not meeting criteria of highly-probable and probable ioCS).
