Abstract

To evaluate the effect and safety of enucleation of insulinoma under the Da Vinci robotic surgical system combination with intraoperative ultrasonography(IOUS) for the localization. The clinical materials of 50 insulinoma cases which underwent IOUS and assisted by the robotic surgical system from September 2012 to September 2014 in Peking Union Medical College Hospital were reviewed retrospectively. The patients were followed up by outpatient review and telephone until October 2014. The diagnostic accuracy rate, operation time, blood loss, complications and cure rate were analyzed by t-test. The locations of tumors were 13 in the head, 21 in the body and 13 in the tail of pancreas, 2 were multiple insulinoma, 1 was ectopic to mesenterium.The average operation time was 142 minutes; the average blood loss was 165 ml.Three(6.0%) patients were transformed to open.One patient experienced postoperative bleeding about 300 ml on the 7(th) day after operation and no infection and perioperative death.Thirty-five cases were of class A and 14 of class B according to the clinical grading of postoperative pancreatic fistula.The blood glucose 60 minutes after tumor dissection was significantly elevated than that before operation ((6.2±1.8)mmo...Continue Reading
