Abstract
The standard surgical procedure for intraductal papillary mucinous neoplasms of the main duct (IPMN-M) or side branch ducts (IPMN-Br) is pancreaticoduodenectomy. IPMN-BR is a more indolent disease with a lower incidence of malignancy. To evaluate the usefulness of organ-preserving pancreatic resections (OPPR) including duodenum-preserving pancreatic head resection (DPHR) and pancreatic head resection with segmental duodenectomy (PHRSD) in patients with IPMN-BR. Surgical outcomes were evaluated in eight IPMN-Br patients: DPHR was performed in 4 patients and PHRSD was performed in 4 patients. In addition, 13 IPMN patients with Whipple resections were included in the analysis. The incidence of postoperative complications was 38% after Whipple resection, 100% after DPHR and 25% after PHRSD. The mean length of hospital stay was 27 days after DPHR, 22 days after Whipple resection and 16 days after PHRSD. Invasive IPMN was found in 38% of the patients in the Whipple group, and noninvasive IPMN was found in 100% of patients who underwent organ-preserving surgery. Pancreaticoduodenectomy remains the treatment of choice in patients with invasive IPMN. PHRSD appears to be a useful procedure for IPMN-Br located in the head of the pancreas.
