Peripartum hysterectomy: An evolving picture

Peripartum hysterectomy (PH) is one of the obstetric catastrophes. Evidence is emerging that the role of PH in modern obstetrics is evolving. Improving management of postpartum hemorrhage and newer surgical techniques should decrease PH for uterine atony. Rising levels of repeat elective cesarean deliveries should decrease PH following uterine scar rupture in labor. Increasing cesarean rates, however, have led to an increase in the number of PHs for morbidly adherent placenta. In the case of uterine atony or rupture where PH is required, a subtotal PH is often sufficient. In the case of pathological placental localization involving the cervix, however, a total hysterectomy is required. Furthermore, the involvement of other pelvic structures may prospectively make the diagnosis difficult and the surgery challenging. If resources permit, PH for pathological placental localization merits a multidisciplinary approach. Despite advances in clinical practice, it is likely that peripartum hysterectomy will be more challenging for obstetricians in the future.     

Peripartum cesarean hysterectomy: critical analysis of risk factors and trends over the years

Objective.?To investigate time trends and risk factors for peripartum cesarean hysterectomy.

Methods.?A population-based study comparing all deliveries that were complicated with peripartum hysterectomy to deliveries without this complication was conducted. Deliveries occurred during the years 1988–2007 at a tertiary medical center. A multiple logistic regression model was constructed to find independent risk factors associated with peripartum hysterectomy.

Results.?Emergency peripartum cesarean hysterectomy complicated 0.06% (n?=?125) of all deliveries in the study period (n?=?211,815). The incidence of peripartum hysterectomy increased over time (1988–1994, 0.04%; 1995–2000, 0.05%; 2001–2007, 0.095%). Independent risk factors for emergency peripratum hysterectomy from a backward, stepwise, multivariable logistic regression model were: uterine rupture (OR?=?487; 95% CI 257.8–919.8, p?<?0.001), placenta previa (OR?=?66.4; 95% CI 39.8–111, p?<?0.001), postpartum hemorrhage (PPH) (OR?=?40.8; 95% CI 22.4–74.6, p?<?0.001), cervical tears (OR?=?22.3; 95% CI 10.4–48.1, p?<?0.001), second trimester bleeding (OR?=?6; 95% CI 1.8–20, p?=?0.003), previous cesarean delivery (OR?=?5.4; 95% CI 3.5–8.4, p?<?0.001), placenta accreta (OR?=?4.7; 95% CI 1.9–11.7, p?=?0.001), and grand multiparity (above five deliveries, OR?=?4.1; 95% CI 2.5–6.6, p?<?0.001). Newborns of these women had lower Apgar scores (<7) at 1 and 5?min (32.7% vs.4.4%; p?<?0.001, and 10.5% vs. 0.6%; p?<?0.001, respectively), and higher rates of perinatal mortality (18.4% vs. 1.4%; p?<?0.001) as compared to the comparison group.

Conclusion.?Significant risk factors for peripartum hysterectomy are uterine rupture, placenta previa, PPH, cervical tears, previous cesarean delivery, placenta accreta, and grand multiparity. Since the incidence rates are increasing over time, careful surveillance is warranted. Cesarean deliveries in patients with placenta previa-accreta, specifically those performed in women with a previous cesarean delivery, should involve specially trained obstetricians, following informed consent regarding the possibility of peripartum hysterectomy.     

Emergency peripartum hysterectomy: The experience of a tertiary referral hospital

Objective(s)The aim of this study was to review the frequency, indication, associated risk factors, rates of maternal morbidity and mortality as well as neonatal outcome after emergency peripartum hysterectomy at a tertiary care referral hospital.Study designA retrospective observational study carried out from November 2008 to 2011.Patients and methodsThe study comprised of 29 patients at Mansoura University Hospitals a tertiary referral hospital Egypt. Frequency, indications, associated risk factors and maternal morbidity and mortality were reported as well as neonatal survival and outcome.ResultsThe frequency of emergency peripartum hysterectomy in our study period was (29/10000 deliveries = 0.29%) and the mean age and parity of the patients were 36.4 ± 8.9 years and 2.9 ± 1.56 respectively. The mean gestational age at the time of delivery was 35.45 ± 2.9 weeks. Twenty-five patients (86.2%) had a history of previous cesarean delivery(ies) meanwhile the others (4/29 = 13.8%) had vaginal delivery(ies). Abnormally adherent placenta and severe postpartum hemorrhage were the main indication for the procedure (11/29 = 37.9%). Other indications included rupture uterus (7/29 = 24.1%), severe uterine atony (7/29 = 24.1%), multiple uterine fibroid (3/29 = 10.3%) and 1 case with severe uterine infection (1/29 = 3.4%). All women received blood transfusion, 5 cases (17.2%) required intensive care unit admission, and 3 cases (10.3%) developed intraoperative arrest, 5 patients (17.2%) had urinary bladder injuries and 2 cases (6.8%) had wound infection. The maternal mortality occurred in 4 cases (13.8%) while overall neonatal survival rate was 86.2% (25/29).ConclusionEmergency peripartum hysterectomy is still high in our locality representing a significant risk for the mother and the baby; hence health care authorities should raise the problem to decrease this burden.     

Emergency peripartum hysterectomy: a comparison of cesarean and postpartum hysterectomy

Objectives

The purpose of this study was to evaluate the incidence, risk factors, indications, outcomes, and complications of emergency hysterectomy performed after cesarean deliveries (cesarean hysterectomy) and vaginal deliveries (postpartum hysterectomy).

Study design

We conducted a retrospective cohort study from 1990 to 2002 of patients who had peripartum hysterectomies at a single tertiary hospital. Comparisons were made between cesarean and postpartum hysterectomies.

Results

There were 55 cases of emergency peripartum hysterectomy (38 cesarean hysterectomies, and 17 postpartum hysterectomies), for a rate of 0.8 per 1000 deliveries. Overall, the most common indication for hysterectomy was uterine atony (56.4%), followed by placenta accreta (20.0%). Average estimated blood loss was 3325.6±1839.2 mL, average operating time was 157.1±75.4 minutes, average time from delivery to completing the hysterectomy was 333.8±275.7 minutes, and the average length of hospitalization was 11.0±7.9 days. The cesarean delivery rate at Grady Memorial Hospital during the study period was 14.2%. There were no statistically significant differences between variables examined when comparisons were made by cesarean vs postpartum hysterectomy.

Conclusion

Uterine atony is the leading indication for emergency hysterectomy performed following cesarean and vaginal deliveries.     

Risk factors for peripartum hysterectomy following uterine rupture

Abstract

Objective: To investigate risk factors for hysterectomy following uterine rupture.

Methods: A population-based study comparing all uterine ruptures with and without hysterectomy between 1988 and 2011 was conducted. Stratified analysis was performed using a multiple logistic regression analysis.

Results: Peripartum hysterectomy complicated 20.7% (n?=?34) of uterine ruptures during the study period (n?=?164). Independent risk factors for hysterectomy following uterine rupture, from a multivariable logistic regression model, were relaparotomy (OR?=?32.2, 95% CI?=?2.5–421.9), extended tears involving the uterine cervix (OR?=?6.1, 95% CI?=?1.5–24.7), severe bleeding requiring packed cells transfusions (OR?=?13.7, 95% CI?=?3.2–58.5) and grand multiparity (≥5 deliveries, OR?=?11.4 95% CI?=?2.7–47.1).

Conclusion: Hysterectomy is not common following uterine rupture. Independent risk factors for hysterectomy include relaparotomy, extended tears involving the uterine cervix, severe bleeding requiring packed cells transfusions and grand multiparity. Trained obstetricians should be involved in cases of uterine rupture and the possibility for conducting hysterectomy should be emphasized.     

Planned cesarean hysterectomy: A preferred alternative to separate operations

Objective: The aim of this study was to evaluate our institutional experience with planned cesarean hysterectomy. Study Design: In this retrospective case-control investigation of a 16-year experience, 100 pregnant women who underwent planned cesarean hysterectomy were compared with 37 patients who underwent cesarean delivery followed by a hysterectomy performed within 6 months. Results: Women undergoing planned cesarean hysterectomy did not have any demonstrable increase in intraoperative or postoperative complications when compared with the cesarean delivery plus later hysterectomy group. Primarily as a result of significantly reduced hospital stay and shorter total operative time, there was a significant financial advantage associated with a single planned cesarean hysterectomy with respect to separate operations. Conclusions: A policy to undertake planned cesarean hysterectomy for carefully selected patients appeared to produce advantages without increasing risks for these patients. Secondarily, it provided resident physicians the opportunity to learn the operation with supervision and under controlled circumstances. (Am J Obstet Gynecol 1999;180:1385-93.)     

腹腔镜辅助阴式子宫切除术与阴式子宫切除术适应证的探讨

目的通过比较腹腔镜辅助阴式子宫切除术(LAVH)与阴式子宫切除术(VH)的不同手术适应证及效果,探讨LAVH与VH手术病人的最佳选择。方法回顾性分析上海瑞金医院1999年6月至2002年12月间LAVH与VH手术病例381例,比较两种手术在手术时间、出血量、术后住院日、术中术后并发症及两者的手术适应证,尤其是子宫大小、盆腔粘连等的不同。结果两组手术在术中出血、手术并发症等方面差异无显著性意义,LAVH手术时间较长与患者子宫大、盆腔粘连者多、手术难度大有关。VH组患者均为正常或小于正常大小的子宫、无盆腔粘连、不伴有附件疾病者,手术适应证明显受限制。结论VH与LAVH均为创伤小、恢复快的微创手术,但VH适合于子宫小、无粘连并伴下垂者,而LAVH扩大了VH的适应证,是值得推广的手术。     

Emergency peripartum hysterectomy in a tertiary Istanbul hospital

OBJECTIVE: To evaluate the incidence, risk factors, indications, outcomes and complications of emergency peripartum hysterectomy performed after cesarean and vaginal deliveries. METHOD(S): We analyzed retrospectively 28 cases of emergency peripartum hysterectomy operations performed between February 2001 and February 2007 at the Istanbul Goztepe Training and Research Hospital, which is a teaching hospital operating under the Turkish Ministry of Health. The indications, risk factors and the associated complications were compared with control groups. Statistical analysis was performed using the STATA version 7.0 statistical package (Stata Corporation, College Station, TX, USA). RESULT(S): The overall incidence of emergency peripartum hysterectomy at our hospital is 0,37 in 1,000 deliveries. Abnormal placental adherence and uterine atony comprised 85% of the indications for peripartum hysterectomy. Postoperative maternal morbidity occurred in 15 cases (54%). Most had a febrile morbidity and depression. Seven patients underwent postpartum histerectomy due to consumptive coagulopathy. There was one maternal mortality (4%) and five perinatal mortalities (18%). The maternal death was due to consumptive coagulopathy after placental abruption. All patients had to receive blood transfusions. The median number of postoperative hospitalization days was 7. CONCLUSION(S): Peripartum hysterectomy is still a dramatic life-saving operation with high risks. The most common reason for abnormal placental adherence is previous uterine procedures.     

Emergency Peripartum Hysterectomy: A 13-Year Review at a Tertiary Center in Kuwait

Objective

To determine the incidence, indications, risk factors, and complications of emergency peripartum hysterectomy (EPH) and to evaluate total versus subtotal hysterectomy for EPH.

Materials and Methods

This is a retrospective case series involving thorough examination of the files of all women who had EPH between January 2000 and December 2012 in the department of Obstetrics and Gynecology, Al-Jahra hospital, Kuwait after taking approval from the ethics committee. Incidence, indications, risk factors, type of hysterectomy, and complications of EPH were obtained from patient files.

Results

There were 63,337 deliveries of which 70.3 % were vaginal deliveries, and 29.6 % were by cesarean section (CS). Sixty-eight women underwent EPH representing an overall incidence of 1 case per 1,000 deliveries. The indications for EPH included abnormal placentation (77.4 %), uterine atony (14.5 %), and uterine rupture (8.1 %). There was one maternal death. Maternal morbidity occurred in 25 (40.3 %) women. The most common complications were mild to severe coagulopathy (19.35 %) and injury to the urinary tract (17.74 %). Injury to the ureter was avoided by placing ureteric stents preoperatively. Our population was significant in having higher rate of CS deliveries (91.9 %), women with prior CS (83.87 %), and high parity (mean 5.8).

Conclusion

Abnormal placentation was the most common indication to perform EPH. The relative risk of EPH was 27 for CS deliveries as compared to vaginal deliveries. There was no significant difference between subtotal versus total hysterectomy with respect to age, parity, previous CS, operative time, blood transfusion, and intra and post operative complications.     

Vaginal length and incidence of dyspareunia after total abdominal versus vaginal hysterectomy

Objective

To evaluate the vaginal length and incidence of dyspareunia after total abdominal hysterectomy compared to vaginal hysterectomy.

Study design

This is a prospective observational study. Sixty-six patients were invited to participate in the study who were already planned to undergo abdominal or vaginal hysterectomy for different benign indications in the OB/GYN department, Sohag University Hospital, during the period from March 2007 till April 2009. Patients were classified into two groups. Thirty-six patients who were planned to undergo total abdominal hysterectomy (TAH) represented the first group, and 30 patients who were planned to undergo vaginal hysterectomy (VH) represented the second group. Vaginal length was obtained just before the operation and three times postoperatively. Pre- and post-operative dyspareunia was reported.

Results

The mean pre-operative and post-operative vaginal lengths in the TAH group were nearly the same (10.5 ± 2.1 cm vs. 10.2 ± 1.8 cm) without statistically significant difference. In the VH group, there was a statistically significant difference between pre- and post-operative vaginal length (10.1 ± 1.9 cm vs. 8.4 ± 1.6 cm). In the TAH group, 2 patients (5%) reported a newly developed post-operative dyspareunia. In VH group, 6 patients (20%) developed dyspareunia after surgery.

Conclusion

Postoperative dyspareunia is more common after vaginal hysterectomy compared to abdominal hysterectomy. This may be attributed to postoperative shortening of the vagina secondary to excessive trimming of the vaginal walls especially if VH was done for utero-vaginal prolapse.     

Emergency peripartum hysterectomy in a tertiary London hospital

Objective The objective was to review all emergency peripartum hysterectomies performed at a tertiary hospital in London, UK, and to identify the risk factors for emergency peripartum hysterectomy.Method A retrospective case control study. The cases consisted of all women who had emergency peripartum hysterectomy between 1 January 1993 and 31 December 2003. Controls were women who delivered immediately before and after the indexed case. Demographic data, medical and surgical histories, pregnancy, intrapartum and postpartum data were collected. Differences between cases and controls were compared with ², Fisher exact and Student t tests. Multiple logistic regression analysis was performed to identify independent risk factors for emergency peripartum hysterectomy.Results There were 15 cases of emergency peripartum hysterectomy in 31,079 deliveries, giving a rate of 0.48 per 1,000. Women who had emergency peripartum hysterectomy were significantly older (mean age 37 years vs. 29 years, P<0.001) and multiparous (P=0.02). More of the cases had a history of uterine surgery (67 vs. 30%, P=0.01), placenta praevia (60 vs. 3%, P<0.0001) and were delivered by caesarean section (86.7 vs. 30%, P=0.003). Eighty percent of the hysterectomies were performed in the daytime and all were done by consultants. Haemorrhage due to placenta praevia was the main indication for emergency peripartum hysterectomy (47%). Independent risk factors for emergency peripartum hysterectomy were older age (odds ratios [OR] 1.2, 95% confidence interval [95% CI] 1.2–1.6), multiparity (OR 2.6, 95% CI 1.3–10.2), history of previous caesarean section (OR 13.5, 95% CI 2.7–65.4), caesarean delivery in index pregnancy (OR 11.6, 95% CI 2.1–68.6) and caesarean delivery in index pregnancy for placenta praevia (OR 18, 95% CI 3.6–69).Conclusion Caesarean deliveries, especially repeat caesareans in women with placenta praevia, significantly increase the risk of emergency peripartum hysterectomy.     

Emergency peripartum hysterectomy: a 9-year review

Objective: To determine the incidence, indications, risk factors, and complications of emergency peripartum hysterectomy. Study design: A retrospective study of the patients requiring an emergency peripartum hysterectomy of a 9-year period was conducted. Emergency peripartum hysterectomy was defined as one performed for hemorrhage unresponsive to other treatment less than 24 h after delivery. Demographic and clinical variables were obtained from the maternal records. Results: There were 34 emergency peripartum hysterectomies out of 117,095 deliveries for a rate of 0.29 per 1,000. Of the 16 cases that were delivered by cesarean section, seven had a previous cesarean section and 18 cases were delivered vaginally, including two using vacuum extraction. Total hysterectomy was performed in 24 patients, and subtotal hysterectomy in ten patients. The indications for hysterectomy were uterine rupture (n=12), placenta accreta (n=10), uterine atony (n=7), and hemorrhage (n=5). There were two maternal deaths, six stillbirths, and two early neonatal deaths. Conclusion: This study identified surgical deliveries, uterine rupture, placenta accreta, and uterine atony as risk factors for emergency peripartum hysterectomy. The most common reason for abnormal placental adherence was a previous cesarean section. Multiparity and oxytocin use for uterine stimulation were among the risk factors for uterine atony that necessitated emergency peripartum hysterectomy.     

Attitudes towards mode of delivery and cesarean on demand in Turkey.

OBJECTIVE: To assess the attitudes of healthcare providers and the public in Turkey towards mode of delivery and cesarean delivery on demand. METHODS: A written questionnaire was given to female healthcare providers and women from the general public, and their answers were analyzed. RESULTS: A total of 329 female healthcare providers and 347 women from the public group completed the survey. In response, 48.1% of healthcare providers and 69.6% of the public group chose vaginal delivery as the preferred mode of delivery (P<0.001). Some 45.3% of healthcare providers and 20.6% of the public group had undergone a cesarean delivery without any medical indications (P<0.001). In addition, 37.8% of healthcare providers and 36.2% of the public group believed that women should have the right to a cesarean delivery on demand. CONCLUSIONS: In the two groups studied the preference for cesarean delivery is higher in Turkish healthcare providers than in the public population. In both groups the attitude towards cesarean delivery on demand is high.     

What is new in peripartum hysterectomy? A seventeen year experience in a tertiary hospital

ObjectiveTo identify changing trends in peripartum hysterectomy (PH), both elective.cesarean hysterectomy and emergency cesarean hysterectomy, at a single training and research hospital over the last 17 years in Istanbul, Turkey.Materials and methodsA retrospective cohort study was performed between January 2001 and September 2017. The records of all patients who had PH at Kanuni Sultan Süleyman Training and Research Hospital were analyzed.ResultsThere were 243 cases of PH during the study period. A total of 266,386 births occurred, of which 60.1% were vaginal deliveries and 39.8% were cesarean sections. The incidence of PH increased from 0.67 per 1000 deliveries to 1.14 per 1000 deliveries during 2001–2008 and 2009–2017, respectively, with an overall incidence of 0.91 per 1000 deliveries during the 17 years. The main indication for PH changed significantly during this time from uterine atony (57.1%) to placenta accreta spectrum (85%). About 37% of women who underwent PH had at least one previous cesarean delivery during 2001–2008, whereas that percentage increased to 95.4% during 2009–2017.ConclusionPlacenta accreta spectrum was the leading cause of PH and was associated with significant maternal morbidity and mortality.     

Postpartum hysterectomy

Objectives: To review cases of postpartum hysterectomy regarding indications, risk factors and complications and compare them with cases of emergency cesarean section. Methods: We conducted a retrospective chart review study of 20 cases of postpartum hysterectomy and 20 cases of emergency cesarean section performed at Sinai Samaritan Medical Center, Milwaukee, Wisconsin, between January 1984 and January 1994. Emergency postpartum hysterectomies were compared with emergency cesarean sections regarding obstetric history, placental location, operative time, blood loss, blood transfusion, intra- and postoperative complications and length of hospitalization. Emergency hysterectomies were reviewed according to their indications for the incidence of complications and length of hospitalization. Pathological diagnoses of the hysterectomy specimens were reviewed. Statistical analyses were performed using the two-tailed Student's t-test and Fisher's exact test. Results: Placenta accreta was the most common indication for emergency postpartum hysterectomy. Prior cesarean section and/or placenta previa were risk factors. Emergency hysterectomies were associated with longer operating times (P < 0.0001), greater blood loss (P < 0.0001), more transfusions (P < 0.001), postoperative complications (P < 0.01), secondary surgeries (P < 0.01) and longer hospitalizations (P < 0.0001) than cases of emergency cesarean section. Conclusions: Emergency postpartum hysterectomy is associated with significant blood loss, need for transfusion, postoperative complications and longer hospitalization partly because of its indications. The combination of prior cesarean section and current placenta previa should alert the obstetrician that an emergency postpartum hysterectomy may be needed.     

A comparison of abdominal and vaginal hysterectomy for the large uterus.

OBJECTIVE: To compare the perioperative outcomes of women with an enlarged uterus (>or=250 g) who had abdominal and vaginal hysterectomies. METHOD: Retrospective study of the perioperative outcomes of 288 consecutive women with an enlarged uterus, of whom 200 underwent an abdominal hysterectomy and 88 a vaginal hysterectomy, all for benign gynecological conditions. RESULTS: Among the perioperative complications, only the risk of ileus was significantly higher in the group that underwent abdominal hysterectomy. Although the need for blood transfusions was similar between the groups, mean perioperative hemoglobin change was significantly lower for women who had the abdominal approach. Vaginal hysterectomy shortened the length of hospitalization significantly but did not affect the operative time. All of these differences remained significant after adjusting for uterine weight (P<0.05). Baseline characteristics were similar between the groups, except for uterine weight. CONCLUSIONS: For women with a uterus weighing 250 g or more, vaginal hysterectomy shortens the hospital stay without significantly increasing perioperative morbidity when compared with the abdominal route.     

Rate of vaginal cuff separation following laparoscopic or robotic hysterectomy

Objective

Vaginal cuff separation is a rare but serious complication following hysterectomy. The goal of our study was to determine the rate of vaginal cuff separation and associated risk factors in patients undergoing laparoscopic or robotic hysterectomy.

Methods

We retrospectively identified patients who underwent a minimally invasive simple or radical hysterectomy at one institution between January 2000 and 2009. Fisher's exact test, Wilcoxon rank sum test and multiple logistic regression were used to determine associations between variables and increased risk of separation.

Results

A total of 417 patients underwent laparoscopic (n = 285) or robotic (n = 132) hysterectomy during the study period. Three hundred and sixty-two underwent simple hysterectomy (249 laparoscopic, 113 robotic) and 57 underwent radical hysterectomy (36 laparoscopic, 19 robotic). Seven (1.7%) patients developed a cuff complication and all had a diagnosis of malignancy. Three (1.1%) patients in the laparoscopy group suffered a vaginal cuff evisceration (n = 2) or separation (n = 1). Four patients in the robotic group (3.0%) had a vaginal evisceration (n = 1) or separation (n = 3). There was no difference based on surgical approach (p = 0.22). Vaginal cuff complications were 9.46-fold higher among patients who had a radical hysterectomy (p < 0.01). Median time to presentation of vaginal cuff complication was 128 days (range, 58-175) in the laparoscopy group and 37 days (range, 32-44) in the robotic group.

Conclusions

The overall risk of vaginal cuff complication was 1.7%. There appears to be no difference in cuff complication rates based on surgical approach. Radical hysterectomy, however, was associated with a 9-fold increase in vaginal cuff complications.
