BACKGROUND: Whether patients with focal pancreatic lesions of benign or borderline pathology should be treated by extended central pancreatectomy rather than by extended classic resectional procedures, such as extended right and left resections, is controversial. METHODS: Between 1992 and 2007, 105 patients underwent operation for focal pancreatic lesions of borderline or benign neuroendocrine neoplasms, cystadenoma, intraductal papillary mucinous neoplasia (IPMN), and secondary metastasis. In all, 35 patients were subjected to extended central pancreatectomy, whereas the remaining 70 patients were treated by an extended classic right resection or an extended classic left resection. Groups were matched according to age, sex, and histopathology. RESULTS: No peri-operative mortality occurred after extended central pancreatectomy and extended classic left resection (n = 35, each). Two (6%) patients died after extended classic right resection. Overall, in-hospital morbidity was 26% after extended central pancreatectomy, 43% after extended classic right resection, and 37% after extended classic left resection. After a median follow-up of 48 months, a local recurrence rate of 17% after extended central pancreatectomy was similar to the corresponding rates of 9% after extended classic left resection and 14% after extended classic right resection. Endocrine and exocrine impairment was less pronounced after extended central pancreatectomy (6% and 9%) than after extended classic left resection (34% and 29%) and extended classic right resection (28% and 24%; P <.05). CONCLUSION: Extended central pancreatectomy for appropriate pancreatic neoplasms is associated with less peri-operative morbidity and mortality than after extended classic left and extended classic right resection. Long-term local recurrence after extended central pancreatectomy is similar to the recurrence rates after extended classic right and classic left resection. Our results suggest that appropriately selected patients will benefit from extended central pancreatectomy because of the maintenance of endocrine and exocrine function.
