简介：AbstractImportance:Scimitar syndrome (SS) is a rare type of congenital heart disease characterized by total or partial anomalous venous drainage of the right lung to the inferior vena cava. However, the surgical repair techniques for SS vary according to patients’ anatomical and pathological features.Objective:This study was performed to analyze the mid-term results of a less invasive surgical correction technique for SS in children.Methods:Eleven patients with SS who underwent surgical repair from January 2012 to March 2020 were retrospectively analyzed. The anomalous scimitar vein (SV) was directly reimplanted to the left atrium, and the concomitant atrial septal defect was simultaneously repaired with cardiopulmonary bypass.Results:Three male and eight female patients were included in the study. Their mean age was 3.1 ± 1.3 years, and their mean body weight was 12.8 ± 3.0 kg. Most patients had symptoms, such as upper respiratory tract infection, dyspnea, and recurrent pneumonia, and two patients had pulmonary hypertension. None of the 11 patients who underwent direct SV reimplantation by right thoracotomy developed bleeding, arrhythmia, heart failure, or perioperative death, and no patients required reoperation during a mean follow-up period of 36.6 ± 15.2 months. Postoperative echocardiography revealed no restenosis or obstruction of the anastomosis in any patients.Interpretation:Surgical repair for SS by right thoracotomy and direct anastomosis of the SV to the posterior wall of the left atrium is safe and effective, with good long-term patency of the reimplanted SV and a low mortality rate.

简介：AbstractBackground:Recent evidence has shown that prophylactic antibiotic treatment in patients with acute pancreatitis is not associated with a significant decrease in mortality or morbidity. The use and efficacy of prophylactic antibiotic treatment in acute pancreatitis remain controversial. This meta-analysis was conducted to assess whether antibiotic prophylaxis is beneficial in patients with acute pancreatitis.Methods:We searched randomized controlled trials (RCTs) of prophylactic use of antibiotics using Medline (PubMed), Embase, the Cochrane Library, and Web of Science. The data were analyzed using Review Manager 5.3 software. We performed pooled analyses for infected pancreatic necrosis, mortality, surgical intervention, and non-pancreatic infection. Odds ratios (ORs) from each trial were pooled using a random or fixed effects model, depending on the heterogeneity of the included studies. Sub-group analysis or sensitivity analysis was conducted to explore potential sources of heterogeneity, when necessary.Results:Totally, 11 RCTs involving 747 participants were included, with an intervention group (prophylactic use of antibiotics, n = 376) and control group (n = 371). No significant differences were found regarding antibiotic prophylaxis with respect to incidence of infected pancreatic necrosis (OR, 0.74; 95% confidence interval [CI], 0.50–1.09; P = 0.13), surgical intervention (OR, 0.92; 95% CI, 0.62–1.38; P = 0.70), and morality (OR, 0.71; 95% CI, 0.44–1.15; P = 0.16). However, antibiotic prophylaxis was associated with a statistically significant reduction in the incidence of non-pancreatic infection (OR, 0.59; 95% CI, 0.42–0.84; P = 0.004).Conclusions:Prophylactic antibiotics can reduce the incidence of non-pancreatic infection in patients with AP.
