简介：AbstractBackground:The incidence of uterine cesarean scar defect (niche) is high, and some patients require surgery. Single-port laparoscopy can reduce post-operative pain, and provide better cosmetic effects. This study was performed to evaluate the safety and superiority of single-port laparoscopy-assisted vaginal repair of uterine cesarean scar defect (niche) in women after cesarean section.Methods:This study included 74 patients who were diagnosed with uterine cesarean niche at the Shanghai First Maternity and Infant Hospital from January 2013 to June 2015. Thirty-seven patients underwent single-port laparoscopy-assisted vaginal surgery as the case group, and the remaining patients underwent vaginal repair surgery as the control group. We collected data from the inpatient and follow-up medical records. The clinical characteristics of these two groups were compared. The odds ratios and 95% confidential intervals were calculated for each variable by univariate and multivariate analyses.Results:Patients who underwent single-port laparoscopy-assisted vaginal repair had a significantly longer operation time (2.3 [2.0-2.7] vs. 2.0 [1.6-2.3] h, P = 0.015), shorter gas passage time (1.2 [1.0-1.5] vs. 1.7 [1.0-2.0] days, P = 0.012), shorter hospital stay (3.1 [3.0-4.0] vs. 4.5 [4.0-6.0] days, P = 0.019), and fewer complications (0 vs. 4 cases). Univariate analysis showed that depth of the niche (P = 0.021) the mild adhesiolysis score (P = 0.035) and moderate adhesiolysis score (P = 0.013) were associated with the bladder injury. Multivariate analysis showed that the moderate adhesiolysis score (P = 0.029; 95% confidence interval, 1.318-3.526) was the strongest independent predictor of bladder injury.Conclusion:This study confirmed the safety and superiority of single-port laparoscopy-assisted vaginal repair of uterine cesarean scars.

简介：以便更精确地在粗野货物产量检验发展中的趋势，我们为货物产量的概率分发建模。等到在港口和处理设备的操作效率乘货物轮船花了，粗野货物产量被决定。粗野货物产量是为到达港口的每艘货物轮船决定货物产量的每个方面的所有复合变量的和。概率分发用Wald方程被决定。结果证明粗野货物产量的可变性首先取决于到达港口的不同货物轮船要求的不同时间。这个模型克服以前的模型的缺点：精确地决定未来的特定的价值的概率的无能粗野货物产量。我们货物产量的建议模型取决于在到达港口和在港口处理设备的运作的能力的一艘货物轮船要求的时间之间的关系。同时，影响粗野货物产量的关键因素被分析。为了测试模型，的效率，在山东省的一个端口的货物卷被用作一个例子。在案例研究，实际结果匹配我们的理论分析。
