    Abstract:
    Radical antegrade modular pancreatosplenectomy (RAMPS) has been reported to provide improved margin resection and lymph node retrieval for tumors of the body and tail of the pancreas compared with standard resection. We examined our experience with RAMPS and standard resection to determine differences in clinicopathologic outcomes. A comparison of RAMPS procedures was made to standard distal pancreatectomy and splenectomy examining various clinicopathologic variables through retrospective chart review. Twenty-six patients underwent distal pancreatectomy with or without splenectomy between November 2004 and June 2011. Twenty patients underwent standard resection and six patients underwent RAMPS procedures for a variety of histologies. As a result of the heterogeneity of diseases, which included benign lesions, margin status was not applicable in some cases and therefore was not assessed overall. Fisher's exact test and Wilcoxon rank sum tests demonstrated a significant difference in number of lymph nodes removed with mean of 4.3 and 11.2 lymph nodes obtained for standard resection and RAMPS, respectively (P = 0.03). The RAMPS procedure for lesions of the body and tail of the pancreas retrieved significantly more lymph nodes than standard distal pancreatectomy and splenectomy. It should be the preferred surgical approach when lymph node count is important for tumor staging.
