Postoperative LEL incidence increased over time. The results of the present study showed a significant correlation with removal of circumflex iliac lymph nodes and cellulitis with the incidence of LEL. Multicenter or prospective studies are required to clarify treatment efficacies.

This method of lymph node preservation is a simple and extremely effective approach for preventing/reducing LEL after pelvic and para-aortic lymphadenectomy for patients with gynecologic malignancies.

There have been few reports on postpartum changes in the uterus during the three months after delivery. The aim of this study was to evaluate uterine morphological changes in women after vaginal delivery (n=262-351) and in women after cesarean section (n=64-82) and to evaluate the relation between breast-feeding and parity, and uterine involution at 1 and 3 months postpartum measured by vaginal ultrasonography. There were no significant differences in parity between the vaginal delivery group and the cesarean section group. The length of the uterus at one month (7.93+/-1.16 cm, mean+/-SD) and, three months (7.03+/-1.19 cm) and the width of the uterus at three months (3.83+/-0.94 cm) after delivery in the cesarean section group were greater than in the transvaginal group (7.64+/-1.03 cm, 6.65+/-0.99 cm, 3.57+/-0.62 cm, respectively). Increasing maternal parity was associated slightly with larger uterine size at one month post partum. The length of the uterus of women with a breast-feeding rate of 80% or more per day was 6.35+/-0.85 cm, and shorter than in women with a rate of 20% or less 7.03+/-1.04 cm, at three months after delivery. The width of the uterine body of women with a breast-feeding rate of 80% or more per day was 3.32+/-0.45 cm, and shorter than in women with a rate of 20% or less 3.87+/-0.66 cm, at 3 months after delivery. Stepwise regression and multiple regression analysis among parity, the history of cesarean section, the breast-feeding rate at one and three months after the delivery, and the restoration of the menses at three months after the delivery showed that the uterine size at one month after the delivery was related to the cesarean section and that the uterine size at three months after delivery was mostly related to the rate of breast-feeding. These results indicated that uterine involution was related to delivery mode at one and three months postpartum, feeding mode at three months postpartum, the menses restoration, and parity. The rate of breastfeeding was mostly related to the uterine size at three months postpartum.

Objective: To determine the association between cervical polyps in early pregnancy and late abortion and spontaneous preterm birth (SPTB). We also aimed to explore the relationship between cervical polyps and cervical insufficiency in the second trimester. Methods:We conducted a retrospective cohort study of 2941 singleton pregnant women between January 2010 and December 2015. The frequency of late abortion and SPTB (before 28, 34, or 37 weeks of pregnancy) was compared between the two groups of 142 (4.8%) patients who had cervical polyps early in the pregnancy (P group) and 2799 who did not (non-P group). Multivariate analysis was performed to identify risk factors for late abortion and SPTB. Results:The incidence of late abortion and SPTB was significantly higher in the P group than in the non-P group. Cervical polyps in early pregnancy were selected as independent risk factors for late abortion and SPTB before 28, 34, or 37 weeks of pregnancy. The P group had a significantly higher rate of cases requiring therapeutic cervical cerclage than the non-P group. Conclusion:Cervical polyps in early pregnancy are risk factors for late abortion and SPTB. They are also associated with the occurrence of cervical insufficiency.
