Abstract
PURPOSE: To determine the rates of trial of labor after cesarean delivery (TOLAC) and complications in Japan. METHODS: We conducted a descriptive study of pregnant women with one prior cesarean section registered between January 2013 and December 2015 in the perinatal database of the Japan Society of Obstetrics and Gynecology. This database is a nationwide institution-based registry in Japan. This study included women who had undergone one prior cesarean delivery and who delivered a singleton by cephalic presentation between 37 and 41 weeks of gestation. We collected data on delivery method, particularly with regard to the involvement of TOLAC or elective repeated cesarean deliveries (ERCD). Rates of TOLAC were investigated by facility type, and we calculated the rates of maternal and perinatal complications including uterine rupture in TOLAC. RESULTS: During the study period, 647,098 births were registered. Among the 34,460 women who met the inclusion criteria, 1730 (5.0%) and 32,730 (95.0%) underwent TOLAC and ERCD, respectively. In total, 76.4% of hospitals did not perform TOLAC at all. Generally in perinatal medical centers, which are better equipped with facilities, 58.7% women did not perform TOLAC. With regard to complications, we identified eight cases (0.46%) of uterine rupture with TOLAC. TOLAC births did not include maternal death and perinatal death. Among women attempting TOLAC, 1532 (88.6%) had successful vaginal births. CONCLUSION: The TOLAC rate in Japan was considerably lower than that reported in other countries, despite comparable complication rates.
