ObjectiveTo study the relationship between the timing of surgery and one-year outcome in patients with infective endocarditis. MethodsWe retrospectively analyzed the clinical data of 97 patients suffered from leftside native valve infective endocarditis with neoplasm, admitted in Shanghai First People's Hospital between January 2000 and December 2011. There were 65 males and 32 females with mean age of 55.2±16.3 years (ranged 29 to 75 years). They were divided into two groups according to whether the surgery was performed within a week after diagnosis. The in-hospital mortality and one-year mortality, embolism and re-infection were calculated and compared between the two groups. ResultsThere was no significant difference in the in-hospital mortality between the early surgery group and the conventional surgery group (1.9% versus 6.7%, P=0.241). While there was a significant difference in the rate of inhospital embolism related complications (1.9% versus 13.3%, P=0.030) between the two groups. There was no significant difference in one-year mortality between the two groups (1.9% versus 8.9%, P=0.122). The incidence rate of embolism related complication was 5.8% in the early surgery group and 20.0% in the conventional surgery group with a statistical difference (P=0.034). There was one patient with recurrent cerebral infarction among the 11 patients of cerebral infarction in the early surgery group,while 6 recurrent patients in the 9 patients with cerebral infarction in the conventional surgery group (9.1% versus 66.7%, P<0.005). ConclusionsEarly surgery in patients with left-side native valve infective endocarditis can't reduce the in-hospital mortality and one-year mortality but does decrease embolic events significantly. Early surgery is feasible in the patients with cerebral infarction.
ObjectiveTo systematically review the short term and long term efficacy of early surgery for infective endocarditis (IE) patients. MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, WanFang Data and CNKI databases for cohort studies concerning the efficacy of early surgery for IE patients from inception to October 2014. Two reviewers independently screened literature, extracted data and assessed the risk bias of included studies. Then meta-analysis was performed by using RevMan 5.3 software. ResultsSixteen cohort studies including 8 141 patients were included. The results of meta-analysis showed that early surgery could reduce the short term mortality (OR=0.57, 95%CI 0.42 to 0.77, P=0.000 4) and long term mortality (OR=0.57, 95%CI 0.43 to 0.77, P=0.000 7) in IE patients. Subgroup analysis showed that early surgery could significantly reduce the short term mortality and long term mortality in patients with native valve endocarditis (NVE). ConclusionEarly surgery can reduce IE patients' short term mortality and long term mortality. Due to the limited quality and quantity of the included studies, more large-scale high-quality studies are needed to verify the above conclusion.
ObjectivesTo systematically review the differences of operative outcomes between early surgery and delayed surgery in multiple ligament injury of knee joint (MLIK) patients.MethodsPubMed, The Cochrane Library, EMbase, CNKI, CBM, WanFang Data and VIP databases were searched to collect cohort studies about operative outcomes of different surgery times in MLIK patients from inception to September 23rd, 2018. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 8 cohort studies involving 153 early and 90 delayed operatively treated patients were included. The results of meta-analysis showed that: compared with delayed surgery, early surgery received higher Lysholm score (MD=7.52, 95%CI 2.00 to 13.04, P=0.008) and superior IKDC score rate (OR=2.97, 95%CI 1.51 to 5.84, P=0.002). There were no significant differences in Tegner score (MD=–0.08, 95%CI –1.07 to 0.92, P=0.88) and ROM (MD=4.08, 95%CI –2.38 to 10.55, P=0.22) between two groups. The main adverse reactions of MLIK included neurovascular injury, deep venous thrombosis of lower extremities, common peroneal nerve injury, tourniquet paralysis and limited joint activity. Early surgery had a lower incidence of complications than delayed surgery (7.1% vs. 30%).ConclusionThe current evidence shows that early surgery can receive higher Lysholm score and superior IKDC score rate in treatment of MLIK, and have a lower incidence of complications. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify above conclusions.
