Abstract
Background
Radical antegrade modular pancreatosplenectomy (RAMPS) is a modification of standard retrograde pancreatosplenectomy (SRPS) used to achieve the dissection of N1 lymph nodes, early vascular control, and negative posterior margins. However, there have been few comparative studies regarding the clinical outcomes of the RAMPS and SRPS procedures.
Methods
Ninety-three patients underwent distal pancreatectomy for the treatment of pancreas body and tail adenocarcinoma between 2000 and 2014. Clinicopathologic data were retrospectively analyzed in this study. We compared short- and long-term outcomes between RAMPS and SRPS. In addition, we investigated the significance of clinicopathologic factors in left-sided pancreatic cancers.
Results
Fifty-three patients underwent RAMPS and 40 patients underwent SRPS. RAMPS revealed a larger number of retrieved lymph nodes [28.4 ± 11.6 vs 20.7 ± 10.1; P = 0.0016], more frequent R0 resection [90.5 vs 67.5 %; P = 0.0053], less intraoperative bleeding than SRPS [485.4 ± 63.3 vs 682.3 ± 72.8 ml; P = 0.0444], and shorter operating time (267.3 ± 11.5 vs 339.4 ± 13.2 min; P < 0.0001) as compared with SRPS. In comparing RAMPS and SRPS, RAMPS showed a tendency for improvement of the median survival times than SRPS (47 vs 34 months) (P = 0.1920). In the multivariate analysis, R1 resection, histologic grade, and vascular invasion for overall survival (OS) were found to be independent factors.
Conclusions
There were a decrease of intraoperative bleeding and an increase in the number of retrieved lymph nodes and the R0 resection rate using RAMPS as compared with SRPS.
