ObjectiveTo systematically review the efficacy and safety of enhanced recovery after pancreaticoduodenectomy surgery (ERAS).MethodsPubMed, EMbase, The Cochrane library, CBM, CNKI and VIP databases were electronically searched to collect clinical controlled trials of comparing ERAS and the traditional rehabilitation management in patients who received pancreaticoduodenectomy from inception to March 31st, 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.2 software.ResultsA total of 12 non-randomized historical controlled trials involving 2 588 patients were included. The results of meta-analysis showed that ERAS shortened postoperative hospital stay (MD=–5.44, 95%CI –7.73 to –3.15, P<0.000 01) and the time to the first passage of flatus (MD=–1.40, 95%CI –2.60 to –0.20,P=0.02), reduced the rate of postoperative complication (OR=0.61, 95%CI 0.52 to 0.72, P<0.000 01), pancreatic fistula (OR=0.81, 95%CI 0.66 to 0.99,P=0.04) and delayed gastric emptying (OR=0.49, 95%CI 0.38 to 0.63, P<0.000 01). However, there was no significant difference in incidences of biliary fistula, abdominal cavity infection, wound infection and postoperative pulmonary infection between two groups.ConclusionsThe application of ERAS in pancreaticoduodenectomy is effective and does not increase postoperative complication. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
Objective To systematically assess the efficacy and clinical significance of antibiotic prophylaxis in severe acute pancreatitis (SAP), so as to provide references for its rational clinical application. Methods For collecting the randomized controlled trials (RCTs) about antibiotic prophylaxis in SAP, a search was conducted in MEDLINE, EMbase, Cochrane Central Register of Controlled Trials, CBM and CNKI from the date of their establishment to August, 2010. After the clinical studies meeting the inclusive criteria were extracted and their quality was assessed. Meta-analysis was conduced by using RevMan 5.0 software. Results Twelve RCTs were included with a total of 777 patients. The results of Meta-analysis showed compared with the control group, the antibiotic prophylaxis group was not associated with a statistically significant reduction in mortality (RR=0.75, 95%CI 0.50 to 1.12), in the incidence of infected pancreatic necrosis (RR 0.82, 95%CI 0.63 to 1.09), in surgical interventions (RR=0.97, 95%CI 0.74 to 1.26), and in the incidence of nonpancreatic infections (RR=0.73, 95%CI 0.48 to 1.10). Conclusion Antibiotic prophylaxis for SAP does not reduce mortality, infected necrosis, or surgical intervention.
Objective To evaluate the efficacy and safety of intraoperative mesenchymal chemotherapy with 5-FU implants in radical gastrectomy of advanced gastric cancer. Methods From January 2008 to September 2009， 102 patients with historically proven advanced gastric cancer were enrolled in our department and were allocated to undergo either radical gastrectomy and intraoperative mesenchymal chemotherapy with 5-FU implants 800 mg（treatment group， n=51）， or radical gastrectomy alone （control group， n=51）. The postoperative complications and recurrence rate between two groups were compared. Results There were no significant differences on the volume of abdominal cavity drainage， count of white blood cells， albumin level， and gastrointestinal adverse events between the two groups （P＞0.05）. After a median follow-up of 28 months， the local recurrence rate was lower among patients in treatment group than that in control group （16.3% vs. 39.1%， P＜0.05）， the survival rate of 3-year was higher in treatment group than that in control group （85.8% vs. 67.3%， P＜0.05）. Conclusions Compared with the control group， there are no significant adverse reactions on patients with advanced gastric cancer who were implanted fluorouraci1 implants during operation， which can reduce local recurrence rates and improve the survival rates.
Objective To systematically review the effectiveness and safety of alanyl-glutamine dipeptide for severe acute pancreatitis (SAP). Methods Such databases as MEDLINE, EMbase, CENTRAL, VIP, WanFang Data, CBM and CNKI were electronically searched from inception to October, 2012 for randomized controlled trials on alanyl-glutamine dipeptide for SAP. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed methodological quality. Then, meta-analysis was performed using RevMan 5.2. Results Five trials were included involving a total of 227 patients. The results of meta-analysis showed that: compared with the control group, the alanyl-glutamine dipeptide group had the lower incidence of SAP complications (RR=0.41, 95%CI 0.20 to 0.82), the lower incidence of infected pancreatic necrosis (RR=0.12, 95%CI 0.02 to 0.89), less time for alleviating bellyache (MD= –0.90, 95%CI –1.72 to –0.08). There was a tendency in decreasing SAP mortality (RR=0.15, 95%CI 0.02 to 1.19) and lessening the recovery time of blood amylase (SMD=0.37, 95%CI –0.04 to 0.79). Conclusion Current evidence shows that, alanyl-glutamine dipeptide can lower the incidence of complications and the incidence of infected pancreatic necrosis, and shorten the time for alleviating bellyache in SAP patients. Due to the limited quality of the included studies, the above conclusion needs to be verified by more high quality studies.
