Percutaneous Transhepatic Venous Sampling of Gastrin

Abstract

REPORTS of the preoperative localization of gastrinomas by percutaneous transhepatic venous sampling1 , 2 have been published, but the data are scanty. Successful identification of a solitary and sporadic nonfamilial gastrinoma may dictate surgical excision of the tumor rather than total gastrectomy.2 , 3 On the other hand, G-cell hyperfunction, a rare cause of hypergastrinemia and florid peptic-ulcer disease, may be confused with gastrinoma but responds to simple antrectomy and vagotomy. The value of transhepatic venous sampling in multiple endocrine neoplasia type I, in which multiple adenomatosis or tumors may occur, has not been evaluated.To assess the value of transhepatic venous sampling, we . . .
