Introduction The age at which women give birth is rising steadily in the western world. Advanced maternal age has been associated with adverse pregnancy outcomes. We assessed the association between advanced maternal age and the risk of adverse maternal and perinatal outcome in primigravid and multigravid women. Material and methods The study was a population‐based cohort study and included women giving birth between January 2000 and December 2018 using data from the Dutch perinatal registration of Perined. Women were divided into age groups. We compared outcomes between women of 40‐44, 45‐49, and over 50 years old (the study groups) with women of 25‐29 years old (reference group), stratified for parity. We employed multivariable regression to correct for possible confounders including methods of conception, multiple pregnancies, ethnicity, and socio‐economic status. Our primary outcomes were maternal and perinatal mortality. Secondary outcomes included common maternal and perinatal complications, as well as cesarean section rate. Results A cohort of 3 700 326 women gave birth during the study period. Of these women, 3.2% were above 40 years of age. Maternal mortality was rare in all groups, but significantly higher in multigravid women over 50 years old. Perinatal mortality was significantly higher in all pregnancies of women over 40 years old, but not for primigravida over 50 years old. The most notable results with the steepest increase were in maternal complications. Both primigravida and multigravida over 40 years old were at a two times higher risk of perinatal mortality, cesarean section, gestational diabetes, hypertensive disorders, and a low Apgar score after 5 minutes. The risk for women over 45 was almost tripled for perinatal mortality and gestational diabetes and six times higher for cesarean section. Women over 50 years old had a seven times higher risk of cesarean section, a four times higher risk of gestational diabetes, postpartum hemorrhage, and neonatal intensive care unit admission, and a 10 times higher risk of hypertensive disorders. Conclusions The risk of adverse maternal and perinatal outcomes for women over 40 years old surges as age increases. A novel aspect was the consistent increased risks not only for primigravid women but also for multigravida.

Introduction There are assertions that vaginal mode may be the preferred approach of minimally invasive hysterectomy, yet rates of laparoscopic hysterectomy (LH) continue to rise while vaginal hysterectomy (VH) rate remains relatively unchanged. The aim of this study is to compare the perioperative outcomes of LH vs VH. Material and methods We identified women who underwent either LH or VH for benign indications between 2009 and 2015 at a large academic institution. A propensity score‐matched analysis was used to adjust for differences between women undergoing VH vs LH. Outcome parameters were perioperative complications (both intraoperative and postoperative), operative time, blood loss, hospital length of stay, conversion and readmission. Results A total of 1921 patients underwent either LH or VH during the study period. In all, 155 patients from each group were successfully matched using propensity score match analysis. While most intra‐ and postoperative characteristics did not differ between groups, LH was associated with lower blood loss during surgery (102.8 ± 166.5 mL vs 185.0 ± 179.0 mL, P < 0.001) and shorter hospital stay (0.9 ± 1 days vs 1.2 ± 0.9 days, P < 0.0001). Concomitant adnexal surgery was performed more frequently during LH (47.7% vs 12.3%, P < 0.0001), and concomitant prolapse surgery was performed more frequently at the time of VH (14.2% vs 68.4%, P < 0.0001). Conclusions Both VH and LH have overall favorable perioperative outcomes; however, LH is associated with lower blood loss and a shorter hospital stay. The results support the trend toward increasing rates of laparoscopic approach to hysterectomy when appropriate.
