Background: Unresectable tumors of the pancreatic head are encountered in up to 20% of patients taken for resection. The objective of this study was to evaluate the complications and outcome associated with palliative surgical procedures to help guide management decisions in these patients.
Methods: Patients with pancreatic head adenocarcinoma taken to the operating room with curative intent who did not undergo pancreatectomy were evaluated.
Results: From 1997 to 2013, 50 patients were explored and found be unresectable due to M1 disease (n = 27, 54.0%) or vascular invasion (n = 23, 46.0%). Among unresectable patients, 34 (68.0%) had a palliative procedure performed including double bypass (n = 13), biliary bypass (n = 7), gastrojejunostomy (n = 5), or cholecystectomy (n = 9). Complications occurred in 22 patients (44.0%), and patients who had a palliative operation had a longer hospital stay and more major complications. Overall survival was reduced in patients treated with a palliative operation.
Conclusions: Despite advancements in endoscopic palliation, operative bypasses are still commonplace in patients with unresectable pancreatic head cancer. In this study, patients treated with operative procedures had a high rate of complications without a notable improvement in outcome. These findings highlight the importance of identifying unresectable disease prior to surgery and support a selective approach to palliative operations.
