[Value of the peroperative association of echography, extemporaneous cytology and immediately available insulin blood levels of the portal vein. Apropos of 2 cases of insulinoma]. / Intérêt de l'association per-opératoire de l'échographie, de la cytologie extemporanée et des dosages d'insulinémie portale avec résultats immédiats. A propos de deux cas d'insulinome.

The authors report two cases of insulinoma managed by per-operative ultrasound and cytology, together with immediate portal vein insulin levels. They stress the value of these per-operative exploratory techniques which reduce the number of pre-operative invasive examinations while ensuring a greater efficacy in the localization and treatment of these tumors.
