{"title":"Recent advances in the localization and surgical management of duodenal gastrinomas.","authors":"G P Lawton,&nbsp;I M Modlin","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Duodenal gastrinomas are now more frequently recognized as the source of hypergastrinemia in patients with Zollinger-Ellison syndrome. The cell lineage of duodenal gastrinomas may differ from that of pancreatic gastrinomas, which accounts for variations in their clinical behavior. Attempts to localize the submucosal tumors are difficult and are limited by their small size. Intraoperative endoscopic transillumination, selective intra-arterial secretin injection, and duodenotomy with mucosal eversion are currently the most sensitive and reliable methods of localization. Endoscopic ultrasonography and somatostatin scintigraphy further enhance the accuracy of preoperative localization of these tumors. Current information based on cure rates and survival data mandates a primary surgical approach in patients with either the sporadic or the multiple endocrine neoplasia type 1-associated form of the disease. Thus, wide local resection of duodenal gastrinomas with removal of all tumor-bearing lymphatic tissue and acid inhibitory pharmacotherapy (proton pump inhibition) may yield 5-year survival rates of 80% to 90%. Similarly, in patients with pancreatic and duodenal gastrinomas as a manifestation of multiple endocrine neoplasia type 1, the additional enucleation of pancreatic lesions with or without distal pancreatectomy has resulted in cure rates of 67% to 100%.</p>","PeriodicalId":79397,"journal":{"name":"Current opinion in general surgery","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"18590221","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although transplantation of the whole pancreas is the only therapy that reliably achieves euglycemia, the complications associated with this procedure and the need for immunosuppression make it undesirable except to a select subpopulation of type I diabetic patients. Islet cell transplantation is the exciting alternative; however, insulin independence has been achieved in only 10% to 20% of patients.

Endocrine tumors of the pancreas. 胰腺内分泌肿瘤

{"title":"Endocrine tumors of the pancreas.","authors":"J B Meko,&nbsp;J A Norton","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>Pancreatic endocrine tumors are rare, yet can cause significant morbidity due to excessive secretion of hormones. Octreotide is effective in reducing the plasma concentrations of many of these hormones. The availability of potent H2-receptor antagonists and omeprazole has altered the emphasis in patients with Zollinger-Ellison syndrome away from total gastrectomy and towards resection of the gastrinoma for potential cure. Fifty percent of insulinomas and gastrinomas are not evident on preoperative imaging studies, despite their sophistication. Calcium angiography, endoscopic ultrasonography, isotope-labeled octreotide scanning, and injection of methylene blue during secretin angiography are recent imaging modalities that have shown promise in the localization of these tumors. Intraoperative ultrasound has emerged as the best method for operative detection of insulinomas. Duodenotomy and intraoperative endoscopic transillumination are especially important in the surgical management of Zollinger-Ellison syndrome because 30% to 40% of gastrinomas are located in the duodenum. The management of patients with multiple endocrine neoplasia type 1 and Zollinger-Ellison syndrome continues to be controversial.
