A consecutive series of patients with Zollinger-Ellison syndrome (ZES)
is reported. A total of 53 cases were diagnosed, treated, and followe
d by one department during the period 1971-1990. Curative surgery was
considered in all cases after suppression of acid secretion and after
localization of the tumors. Exploratory laparotomy was not employed. O
f the 53 patients 13 (24%) died from metastatic gastrinoma during the
study. Tumors were ultimately located in 31 of the patients, and 21 of
these patients were operated. A total of 12 patients (21%) were cured
. The best results were obtained after Whipple pancreaticoduodenectomy
in patients with small tumors located after percutaneous transhepatic
portography with blood sampling for gastrin assay. In this group 9 of
10 operated patients were cured. Multiple endocrine neoplasia type I
did not seem to preclude curative resection. The findings support an a
ggressive attitude toward local diagnosis and surgical treatment in ZE
S patients, but they also stress the need for improvements in methods
for localizing tumors.
