BACKGROUND/AIMS: The efficacy of preoperative localization methods and the results of the surgical treatment of @entity9608 were studied. METHODOLOGY: Fifty-nine @entity1 referred for surgical treatment were studied and the results of the diagnostic tools for @entity5 localization were compared with findings at surgical intervention. The influence of the type of surgical procedure in the immediate and late postoperative course was also studied. RESULTS: Ultrasonography had a sensitivity of 30%, computed tomography 25%, angiography 54%, portal vein sampling 94%, endoscopic ultrasonography 27% and magnetic resonance 17%. Intraoperative palpation localized 98.2% of the @entity5 and by the addition of intraoperative echography, all lesions were identified. In 55 @entity1 with benign lesions, 22 enucleations, 25 distal pancreatectomies, 7 pancreatectomies plus enucleation and one duodenopancreatectomy were performed. @entity5 were treated by pancreatic resection, postoperative hepatic artery embolization and systemic chemotherapy. There was no postoperative mortality. @entity3472 was the most common complication. Three @entity1 who underwent distal pancreatectomy developed late @entity6 (9.3%). CONCLUSIONS: Extensive preoperative investigation, mainly with invasive methods, is not indicated and by combining intraoperative palpation and echography most of the cases can be adequately dealt with. Preservation of pancreatic tissue with enucleation and preservation of the spleen are the best choice for treatment of @entity9608 .
