Pancreas sparing duodenectomy versus pancreaticodudoenectomy for duodenal carcinoma: a comparison study

Background: Pancreas-sparing duodenectomy (PSD) may be an alternative to pancreaticoduodenectomy (PD) for duodenal cancers located distant from the ampulla. PSD avoids the potential complications of a pancreaticoenteric anastomosis, but the long-term outcomes are unknown. Methods: Patients who underwent surgical resection of duodenal cancer were identified from a prospectively maintained database. Clinical and pathological data were collected, and long-term cancer-related outcomes were analyzed. Results: 19 patients underwent PSD and 60 PD between January 1993 and March 2014. Morbidity (p=0.196), 90-day mortality (p=0.379) and length of stay (p=0.137) were similar in both groups. However, there were more anastomotic leaks in the PD group (33% versus. 5%; p=0.017). Lymph node yield (p
