摘要Background::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.
