title: [Standardized surgical concept for the diagnosis and therapy of Zollinger-Ellison syndrome].
abstract: Between 1987 and 1991, 16 patients (13 females, three males; mean age 52.4 [33-73] years) with Zollinger-Ellison syndrome (ZES) were treated according to a standardized surgical concept. The diagnostic work-up consisted of measuring serum gastrin levels, pre-operative localization by ultrasound and abdominal computed tomography, as well as extensive staging by laparotomy. As complete a tumour resection as possible was the aim of treatment in 15 patients, while in one patient it was to reduce the tumour mass. In six patients who had resection of a solitary tumour there was no evidence of recurrence after 6-42 months of follow-up. Exploration of the duodenum made it possible to identify and then remove a small gastrinoma of the duodenal wall in three patients. No gastrinoma was found in one patient despite extensive exploration. In a further four patients the laparotomy was purely exploratory, because diffuse metastasization was found. In four patients the primary tumour and, where present, the regional lymph nodes were removed, but the signs of ZES persisted, i.e. the intervention was merely palliative. In one female patient, reduction of tumour mass was necessary because the symptoms could not be controlled by conservative measures: she died postoperatively from toxic hepatitis. This experience indicates that standardized surgical intervention achieves potentially curative results in nearly 40% of patients. Including the duodenum in the surgical exploration allows the identification of even small gastrinomas of the duodenal wall. It is concluded that all patients with ZES but no evidence of diffuse metastases should undergo surgical treatment.
