A systematic review of radical antegrade modular pancreatosplenectomy for adenocarcinoma of the body and tail of the pancreas. Issue 1 (January 2017) - Zhou, Yanming
Abstract: Background: To assess the published evidence on clinical outcomes following radical antegrade modular pancreatosplenectomy (RAMPS) for adenocarcinoma in the body or tail of the pancreas. Method: PubMed and Chinese Biomedical Literature databases were searched. The results of comparisons between RAMPS and standard retrograde pancreatosplenectomy (SRPS) were analyzed by meta-analytical techniques. Results: The literature search identified 13 observational studies involving 354 patients undergoing RAMPS. The overall morbidity and 30-day mortality was 40% and 0% respectively. The R0 resection rate was 88%; the median number of retrieved lymph nodes was 21; and the median 5-year overall survival rate was 37%. The result of meta-analysis showed that RAMPS was associated with a significantly less intraoperative bleeding [weighted mean difference −195.2 (95% confidence interval (CI) −223.27 to −167.13); P < 0.001], a greater number of retrieved lymph nodes [odds ratio (OR) 6.19 (95% CI 3.72 to 8.67); P < 0.001] and a higher percentage of R0 resection [OR 2.46 (95% CI 1.13 to 5.35); P = 0.02] as compared with SRPS. Conclusion: The current literature provides supportive evidence that RAMPS is a safe and effective procedure for adenocarcinoma in the body or tail of the pancreas, and is oncologically superior to SRPS.
