- Abstract
BACKGROUND: Experience with minimally invasive surgery for organic hyperinsulinism is limited. No criteria for patient selection with special regard to sporadic, hereditary, multiple and malignant tumors have been defined. METHODS: The estimated success rate of endoscopic surgery was retrospectively calculated by analysing 34 consecutive patients with organic hyperinsulinism operated on by open surgery. A literature search was undertaken to better define indications for endoscopic procedures. Differences in postoperative outcome (morbidity) between endoscopic and open procedures were analysed. RESULTS: Twenty-eight of 31 patients (90%) with solitary insulinomas and one of three patients with multiple insulinomas were correctly localized preoperatively. Twenty-six enucleations (76%) and eight distal resections (24%) including one endoscopic tail resection were performed. Theoretically only 14 out of 34 patients (41%) would have been suitable for endoscopic surgery (8 enucleations and 6 patients for distal resections which were enucleated using an open approach). Pancreatic fistulas were documented in three patients (9%). Reviewing 34 publications, 49 enucleations, 36 distal resections and 15 conversions to open surgery were performed, showing a higher proportion of distal resections in endoscopic surgery. The spleen was preserved in 88% of cases. Fourteen fistulas occurred after enucleations. CONCLUSIONS: Only solitary insulinomas localized in the pancreatic tail or superficially in the body or head may be candidates for endoscopic procedures. Patients with multiple insulinomas, MEN-1 syndrome or malignancy should undergo open surgery.
