Reflections on peripartum hysterectomy: A 10‐year retrospective observational study in Northeast China

Abstract

ObjectiveTo explore the change trends in incidence and leading factors to peripartum hysterectomy (PH) at a regional tertiary medical center in northeast China.MethodsThis was a retrospective observational study of all PH cases conducted at Shengjing Hospital between January 1, 2012 and December 31, 2021. Information on maternal characteristics of pregnancy and delivery, indications of PH, inventions before hysterectomy, complications, and maternal and neonatal outcomes obtained from the Shengjing Hospital Information System were analyzed.ResultsAmong a total of 157 553 deliveries, there were 127 cases of PH (overall PH incidence: 0.85/1000 deliveries); 120 patients (94.49%) underwent hysterectomy after cesarean section, and seven (5.51%) underwent vaginal delivery (P < 0.001). Abnormal placentation was the leading indication for PH (101, 79.53%), including placenta previa (PP) with placenta accreta spectrum (PAS) (93, 73.23%), PP alone (5, 3.94%), and PAS alone (3, 2.36%). Among the patients who underwent PH with abnormal placentation, 92.08% had at least one cesarean section (P < 0.001) and 20.19% had bladder injury (P = 0.044). All maternal deaths (n = 2) occurred in referral patients, and the maternal mortality rate was 1.57/100 hysterectomies.ConclusionAbnormal placentation was the primary indication for PH. For such patients, adequate assessment of their condition and complete communication are strongly recommended. The identification of high‐risk groups for postpartum hemorrhage, timely and effective rescue, and referral are equally important for avoiding PH.
