Improvement of gastric emptying by enhanced recovery after pancreaticoduodenectomy

BACKGROUND： Enhanced recovery after surgery（ERAS） has improved postoperative outcomes particularly in colorectal surgery. This study aimed to assess compliance with an ERAS protocol and evaluate its effect on postoperative outcomes in patients undergoing pancreaticoduodenectomy. METHODS： Fifty patients who had received conventional peri operative management from 2005 to 2009（conventional group）were compared with 75 patients who had received perioperative care with an ERAS protocol（fast-track group） from 2010 to2014. Mortality, complications, readmissions and length of hospital stay were evaluated and compared in the ***： Compliance with each element of the ERAS pro tocol ranged from 74.7% to 100%. Uneventful patients had a significant higher adherence to the ERAS protocol（87.5% vs40.7%; P〈0.001）. There were no significant differences in de mographics and perioperative characteristics between the two groups. Patients in the fast-track group had a shorter time to remove the nasogastric tube, start liquid diet and solid food pass flatus and stools, and remove drains. No difference was found in mortality, relaparotomy, readmission rates and over all morbidity. However, delayed gastric emptying and length of hospital stay were significantly reduced in the fast-track group. The independent effect of the ERAS protocol in reduc ing delayed gastric emptying and length of hospital stay was confirmed by multivariate ***： ERAS pathway was feasible and safe in improving gastric emptying, yielding an earlier postoperative recovery, and reducing the length of hospital stay.

Prevalence of hepatitis B and C markers among refugees in Athens

AIM: To assess the prevalence of hepatitis B and C serological markers in a population of refugees living in ***: One hundred and thirty refugees (81 males and 49 females, mean age ±SD: 31.7±8 years) were included in the study. The hepatitis B virus surface antigen (HBsAg),the hepatitis B virus core antibody (anti-HBc) and the hepatitis C virus antibody (anti-HCV) were detected using a third-generation ***: Twenty individuals (15.4%) were HBsAg positive and 69 (53.1%) were anti-HBc positive. The prevalence of HBsAg and anti-HBc was higher among refugees from Albania and Asia (statistical significant difference, P＜0.008 and P＜0.001 respectively). The prevalence of these markers was found irrelevant to age or sex. Anti-HCV was detected in the serum of 3 individuals (2.3 %). No differences among age, sex or ethnicity regarding anti-HCV prevalence were ***: It can be concluded that refugees living in Athens are an immigrant population characterized by a high incidence of HBV infection. The prevalence of HBV markers is higher among refugees from Albania and Asia. It is therefore believed that the adherence to general precautions and the initiation of HBV vaccination programs will be necessary in the future, especially in these *** the prevalence of HCV infection seems to be relatively low, extended epidemiological surveys are needed to provide valid results.
