Abstract
Background. The existence of lymph node (LN) primary gastrinoma as a cause of Zollinger-Ellison
syndrome is controversial. We reviewed our experience with patients in whom gastrinomas
were identified and excised only from LNs.
Methods. From 1982 to 1992, 110 patients with ZES underwent exploration for gastrinoma and
21 (19%) had disease limited to one or more LNs. Standardized exploration included
intraoperative ultrasonography, introoperative endoscopy with transillumination, and
exploratory duodenotomy in 86%, 67%, and 24% of patients, respectively. Each patient
underwent yearly biochemical and radiologic follow-up.
Results. Thirteen patients (62%) with a median follow-up period of 5.8 years had an initial
biochemical cure, whereas eight patients (38%) with a median follow-up period of 3.6
years had persistent disease. Of the 13 patients whose condition initially returned
to normal, four have had biochemical recurrence, with a median time to recurrence
of 4.2 years and a median follow-up period of 7.4 years. Nine patients (43%) remain
biochemically cured, with a median follow-up period of 5.3 years.
Conclusions. Resection of apparent LN primary gastrinoma is warranted, because 43% of those who
underwent resection had no evidence of disease, with a median follow-up period of
5.3 years.
