The aim of this research was to study the feasibility,safety and clinical effects of spleen and splenic vessel-preserving distal pancreatectomy.Methods A retrospective review was performed for 26 patients undergoing distal pancreatectomy for benign or low grade malignant disease with splenectomy （n=13） or splenic preservation （n=13） at the First Hospital of Sun Yat-sen University and Guangdong General Hospital in Southern China from May 2002 to April 2009.Results All 26 pancreatectomies with splenectomy or splenic preservation were performed successfully. There was no statistically significant difference between two groups in mean operative time （（172±47） minutes vs. （157±52） minutes, P ＞0.05）, intraoperative estimated blood loss （（183±68） ml vs. （160±51） ml, P ＞0.05）, incidence of noninfectious and infection complication and mean length of postoperative hospital stay （（10.1±2.2） days vs. （12.1 ±4.6） days, P ＞0.05）. The platelet counts examined one week after operation were significantly higher in the distal pancreatectomy with splenectomy group than the other group （（37.3±12.8）×109/L vs. （54.7±13.2）×109/L, P ＜0.05）.Conclusions Spleen-preserving distal pancreatectomy appears to be a feasible and safe procedure. In selected cases of benign or low-grade malignant disease, spleen-preserving distal pancreatectomy is recommended.展开更多

The aim of this study was to evaluate the postoperative clinical outcomes of patients undergoing both methods. DATA SOURCES： Database search of PubMed, Embase, Scopus, Cochrane, and Google Scholar was performed （2000-2014）; key bibliographies were reviewed. Qualified studies compar- ing patients undergoing SPDP with either SVP or WP, and as- sessing postoperative complications were included. Calculated pooled risk ratio （RR） with the corresponding 95% confidence interval （CI） by random effects methods were used in the meta-analyses. RESULTS： The search yielded 215 studies, of which only 14 observational studies met our selection criteria. The studies included 943 patients in total; 652 （69%） underwent SVP and 291 （31%） underwent WP. Overall, there was a lower incidence of splenic infarction （RR=0.17; 95% Ch 0.09-0.33; P〈0.001）, gastric varices （RR=0.16; 95% Ch 0.05-0.51; P=0.002）, and intra/postoperative splenectomy （RR=0.20; 95% Ch 0.08-0.49; P〈0.001） in the SVP group. There was no difference in in- cidence of pancreatic fistula （WP vs SVP, 23.6% vs 22.9%;P=0.37）, length of hospital stay, operative time or blood loss. There was moderate cross-study heterogeneity. CONCLUSIONS： SVP is a safe, efficient and feasible technique that may be used to preserve the spleen. WP may be more suit- able for large tumors dose to the splenic hilum or those associ- ated with splenomegaly. Randomized clinical trials are justified to examine the long-term benefits of SVP-SPDP.展开更多
