Favourable response to conservative surgery for extra-pancreatic gastrinoma with lymph node metastases.
Five patients with the Zollinger-Ellison syndrome who had extra-pancreatic (duodenal or paraduodenal) gastrinoma with lymph node metastases responded favourably to simple excision or mere shelling out of macroscopic tumour. Acid studies, serum gastrin and the secretin test became normal in all cases in the immediate postoperative period and remained so in three of the five patients when tested at 57, 33 and 8 months. The tests became abnormal in two patients when tested 8 and 53 months after surgery, but both patients are currently well-controlled on ranitidine 150 mg b.d. 22 and 65 months respectively after surgery. These results suggest that in patients with extra-pancreatic gastrinoma who have lymph node metastases simple excision of all macroscopic tumours may offer the prospect of long-term control. The place of total gastrectomy in such patients is questioned.
