Objective:To evaluate the safety and outcome of multivisceral pancreatic resections for primary pancreatic malignancies.Background:Curative resection is the only potential cure for patients with pancreatic cancer, but some patients present with advanced tumors that are not resectable by a standard pancreatic resection. Data on risk and survival analysis of extended pancreatic resections is limited.Methods:One hundred one patients who had a multivisceral pancreatic resection between 10/2001 and 12/2007 were identified from a prospective database, and perioperative and long-term results were compared with those of 202 matched patients with a standard pancreatic resection. Uni- and multivariate regression analysis were performed to identify parameters that are associated with perioperative morbidity. Long-term survival was evaluated.Results:Colon, stomach, adrenal gland, liver, hepatic or celiac artery, kidney, or small intestine were resected in 37.6%, 33.7%, 27.7%, 18.8%, 16.8%, 11.9%, and 6.9% of the 101 patients with multivisceral resection, respectively. Additional portal vein resection was performed in 20.8% of patients. Overall and surgical morbidity but not mortality was significantly increased compared with standard pancreatic resections (55.5% vs. 42.8%, 37.6 vs. 25.3%, and 3.0% vs. 1.5%, respectively). Uni- and multivariate analysis identified a long operative time and the extended multivisceral resection of 2 or more additional organs as independent risk factors for intraabdominal complications or need for relaparotomy. Median survival was comparable to that of standard pancreatic resections.Conclusions:Multivisceral resections can be performed with increased morbidity but comparable mortality and long-term prognosis as compared with standard pancreatic resections at high volume centers. Increased morbidity is related to extended multivisceral resections with a long operative time.
