Is pancreaticodoudenectomy with vascular resection a safe procedure in developing country? Early outcomes and review of national literature

Abstract

IntroductionSafety of extended lymphadenectomy (EL) ± vascular resection in patients undergoing pancreaticoduodenectomy (PD) in resource limited settings is not well established. The objective of this study was to report outcomes of PD resection with EL ± vascular resection from Pakistan and review national literature. MethodsData of patients who underwent PD between 2011 and 2014 was reviewed. A total of 66 patients were included in the study. Primary outcome was 90 day morbidity and mortality. Secondary objective was 2 year overall survival. ResultsMedian age was 57 (32–82) years. Majority patients had locally advanced (pT3/T4) tumors and nodal involvement i.e. 44 (71%) and 42 (67.8%). Mean number of excised lymph nodes and positive lymph nodes was 28.2 ± 12.8 (range 3–62) and 4.8 ± 6.9 (range 0–27) respectively. There were 13 vascular resections including 3 arterial resections. Overall 90 day morbidity was 31.8% and mortality was 3%. No difference in complication rate was observed in patients who did and did not undergo vascular resection i.e. 18% versus 34.5% (P = 0.1). Similarly, median survival was 11 (3–24) months and 11 (1–36) months and not significantly different (P = 0.5). ConclusionIn developing countries, extended lymphadenectomy with vascular resection can be safely performed with pancreaticoduodenectomy in specialized hepatobiliary units.
