Abstract
Three patients with gastrinoma underwent the following examinations 1 preoperative intravenous glucagon test to enable a definitive diagnosis 2 intraarterial glucagon injection test to localize the tumor and 3 intraoperative and postoperative intravenous glucagon test to confirm the completeness of the resectionSerum gastrin levels increased in response to intravenous glucagon in all three patients preoperatively Computed tomography scans revealed a tumor in the lesser omentum pancreatic head and the pancreatic uncinate in cases 1 2 and 3 respectively Intraarterial glucagon test revealed that the feeding artery for the tumor was the left gastric artery in case 1 and the superior mesenteric artery in case 3 Resection of the remnant stomach with tumor pancreaticoduodenectomy with portal vein resection and enucleation of the tumor were performed in cases 1 2 and 3 respectively Serum gastrin levels did not increase in response to intravenous glucagon intraoperatively and postoperatively in cases 1 and 3 Although intravenous glucagon caused a slight increase in serum gastrin in case 2 no recurrent tumors were evident
