SSM only has modest accuracy to predict varices independent of NSBB use. An SSM cutoff value of 18.9 kPa may be adopted to achieve a high negative predictive value to rule out varices.

Background There has been limited literature regarding the influence of hamstring autograft diameter on the outcome of anterior cruciate ligament (ACL) reconstruction in Asian population. This study was undertaken to investigate the failure rate after ACL reconstruction among Chinese patients treated with hamstring tendon autografts of different diameters. Our hypothesis was that an increase in hamstring tendon autograft diameter would reduce the risk of graft failure. Methods A retrospective review of 394 consecutive patients who underwent ACL reconstruction using quadrupled semitendinous and gracillis autografts from 2009 to 2018 at our centre was performed. Logistic regression analysis was used to determine the relationship between graft failure rate and predictor variables, including hamstring graft diameter, gender and age. Results Hamstring graft diameter of 8.0 mm or more was found to be associated with significant reduction of risk in graft failure rate (P = 0.001, Relative Risk 0.19). No significant association was found between graft failure rate and gender or age. Conclusion Hamstring graft diameter 8.0 mm or greater is associated with decreased graft failure rate and revision rate in our local Chinese population.

Background:A growing amount of evidence has suggested an association between preoperative leukocytosis and postoperative complications across a variety of surgeries. The aim of this study was to evaluate the impact of preoperative leukocytosis on the prognosis of geriatric patients with hip fracture after surgery. Methods:This retrospective cohort included 1007 patients age 65 yr and older who underwent surgery for hip fracture between January 2016 and December 2019 at a district general hospital. Outcomes measured included surgical-site infection and 30-day and 1-year mortality. A multivariate logistic regression model was constructed in order to test whether leukocytosis was an independent predictor of morbidity and mortality in patients with hip fracture. Results:After adjustment for covariates, leukocytosis was not found to be a significant independent predictor of poor outcome after geriatric hip-fracture surgery. Delay of surgery longer than 48 hr and dementia were found to be independent variables associated with increased risk of surgical-site infection. The predictors of 30-day mortality were male gender and the use of anticoagulant or antiaggregant medications, whereas male gender, delay of surgery more than 48 hr, dementia and hypoalbuminemia were associated with increased 1-year mortality. Conclusions:Preoperative leukocytosis was not associated with adverse postoperative outcome after geriatric hip-fracture surgery. The more reliable variables for prediction of surgical outcome in geriatric patients with hip fracture were delay in surgery, gender, hypoalbuminemia, dementia, and use of anticoagulant or antiaggregant medications.
