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

Blood tests showed thrombocytopenia and high liver enzymes. Computed tomography scan revealed the presence of hypodense lesions suggestive of splenic infarction. Echocardiography was without abnormalities. Laboratory evaluation for thrombophilia was negative. A bone marrow aspiration and a bone marrow biopsy were normal. Brucella serology was positive. The patient was treated with doxycycline, rifampicin and streptomycin for 12 weeks. Fever, abdominal pain and thrombocytopenia resolved promptly. At one year of follow-up, he remained well and no splenic infarction could be detected on ultrasonography.展开更多
