Scar Ectopic Pregnancy as an Uncommon Site of Ectopic Pregnancy: A Case Report and Literature Review

A cesarean scar pregnancy is a rare type of ectopic pregnancy that occurs when a fertilized egg implants in the scar from a previous cesarean section. It is a serious condition that can lead to significant morbidity and mortality if not managed promptly and appropriately. In this literature review and case report, we discuss the etiology, diagnosis, and management of cesarean scar pregnancy. We conducted a comprehensive search of relevant literature using electronic databases and included studies that reported on the diagnosis and management of cesarean scar pregnancy. We also present a case report of a patient with cesarean scar pregnancy who was managed surgically. The diagnosis of cesarean scar pregnancy is primarily done via transvaginal or transabdominal ultrasound, and medical or surgical management can be used depending on the gestational age, hemodynamic status, and patient preferences. The surgical approach, which involves hysteroscopy, laparoscopy, or laparotomy, is usually preferred, since it is associated with fast recovery and lower recurrence rates. However, it is crucial to consider the patient's plans for future fertility when selecting the management approach. In conclusion, cesarean scar pregnancy is a rare but potentially life-threatening condition that requires prompt and appropriate management. Early diagnosis and treatment can prevent significant morbidity and mortality, and surgical management is usually preferred due to its higher success rates and lower recurrence rates.

Laparoscopic hemostasis and drainage for postpartum retroperitoneal hematoma complicated with an infection: A case report and surgical video

Introduction

and importance: Postpartum retroperitoneal hematomas are a potential complication of childbirth. The management of secondary infections of such hematomas has not been fully elucidated. We present a typical case of such management via laparoscopic surgery, and include a surgical video.

Case presentation

A woman in her 20s experienced fever and right lower quadrant pain and distension on postpartum day 2. Pelvic examination revealed a hump on the vaginal wall on the right side of the uterine cervix, and ultrasonography revealed a hematoma. Contrast-enhanced computed tomography revealed no active extravasation into the hematoma. Conservative antibiotic treatment was started; however, on postpartum day 6, her pain increased and her C-reactive protein concentration and white blood cell count were high. Magnetic resonance imaging revealed a paravaginal/upper vaginal wall hematoma (80 × 70 × 63 mm) located to the right of the uterus and bladder. Hence, laparoscopic drainage was performed on postpartum day 7. The retroperitoneal hematoma was incised and drained. The source of bleeding was the right vaginal vein, and bleeding was halted via electrocoagulation. The patient's symptoms improved immediately, and the postoperative course was uneventful.

Clinical discussion

The laparoscopic approach enabled immediate hemostasis and identification of the source of bleeding. The drainage route was cleaner than would be possible via a vaginal approach, possibly preventing postoperative retrograde re-infection.

Conclusion

Laparoscopic surgery for postpartum retroperitoneal hematoma with infection was useful for both drainage and hemostasis.

•

Laparoscopic treatment of a retroperitoneal postpartum hematoma with infection.

•

Laparoscopy enabled sufficient drainage and surgical hemostasis of this hematoma.

•

Laparoscopic drainage prevented retrograde re-infection via vaginal drainage.

Prophylactic Intraoperative Uterine Artery Embolization During Cesarean Section or Cesarean Hysterectomy in Patients with Abnormal Placentation: A Systematic Review and Meta-Analysis

PURPOSE

To evaluate the effectiveness and safety of prophylactic intraoperative uterine artery embolization (UAE) performed immediately after fetal delivery during planned cesarean section or cesarean hysterectomy in patients with placenta accreta spectrum disorder or placenta previa.

METHODS

A systematic search was conducted on Ovid MEDLINE and Embase, PubMed, Web of Science, and Cochrane databases. Studies were selected using the Population/Intervention/Comparison/Outcomes (PICO) strategy. The intraoperative blood loss and the rate of emergent peripartum hysterectomy (EPH) were the primary outcomes, whereas the length of hospital stay and volume of blood transfused were the secondary outcomes. A random-effects model was employed to pool each effect size. The cumulative values of the primary outcomes were calculated using the generic inverse variance method.

RESULTS

Eleven retrospective cohort studies and five case series were included, recruiting 421 women who underwent prophylactic intraoperative UAE (UAE group) and 374 women who did not (control group). Compared with the control group, the UAE group had significantly reduced intraoperative blood loss (p = 0.020) during cesarean section or cesarean hysterectomy. Furthermore, the EPH rate was also significantly decreased (p = 0.020; cumulative rate: 19.65%), but not the length of hospital stay (p = 0.850) and volume of pRBC transfused (p = 0.140), after cesarean section in the UAE group. The incidence of major complications was low (3.33%), despite two patients with uterine necrosis.

CONCLUSION

The currently available data provides encouraging evidence that prophylactic intraoperative UAE may contribute to hemorrhage control and fertility preservation in women with abnormal placentation.

Knowledge of iatrogenic premature ovarian insufficiency among Chinese obstetricians and gynaecologists: a national questionnaire survey

Background

With increasing cases of iatrogenic premature ovarian insufficiency (POI), more clinicians are required to counsel patients regarding the gonadotoxic effects of iatrogenic treatments. This survey aimed to explore obstetricians and gynaecologists’ knowledge regarding iatrogenic POI. A national online questionnaire survey was conducted across China. Respondents were asked to select the iatrogenic condition(s) that can cause POI based on their experience and knowledge.

Results

Of the 5523 returned questionnaires, 4995 were analysed. Among tumour therapies causing POI, most respondents agreed that radiotherapy (73.5% of respondents) and chemotherapy (64.1%) are risk factors for POI. While only 6.5 and 7.8% of the gynaecological oncologists believed that tumour immunotherapy and tumour-targeting therapy, respectively, may cause ovarian impairment, 31.8 and 22.2% of the non-gynaecologic oncologists believed that these therapies could affect ovarian health. Most respondents believed that ovarian cystectomy (54.4%) was a risk factor for POI. In contrast, only a few respondents believed that hysterectomy with bilateral salpingectomy (39.6%) and uterine artery embolisation (33.5%) could cause ovarian impairment. Only 30.5% of respondents believed that immunosuppressants (ISs) increased the risk of POI. Views differed with experience and hospital setting.

Conclusions

The knowledge of gonadal toxicity due to traditional tumour treatments is generally high among Chinese obstetricians and gynaecologists. A misunderstanding may exist in primary care hospitals and general gynaecologists regarding a link between novel tumour treatments and POI, owing to the lack of convincing evidence. Knowledge of POI caused by hysterectomy and ISs should be improved.

Maternal morbidity and mortality due to placenta accreta spectrum disorders

Placenta accreta spectrum (PAS) disorders are an increasing health problem in many parts of the world. They are an important risk factor for adverse maternal outcomes related to delivery, with a reported 18-fold increase in maternal morbidity. Profuse haemorrhage after attempting to remove the placenta is the most frequent complication and can lead to major maternal morbidity and ultimately to maternal death. Morbidity can also arise from the multiple procedures required to treat PAS disorders. Intensive care unit admission, mechanical ventilation, infection, and prolonged hospitalization are common in these patients. Long-term complications related to infertility and psychological disturbances can also occur and may have a strong and long-lasting impact on women's health. Antenatal diagnosis allows for appropriate scheduling of delivery and referral to a specialized centre and has been shown to reduce maternal morbidity and mortality.

Cesarean delivery with and without uterine artery embolization for the management of placenta accreta spectrum disorder-A comparative study

INTRODUCTION

The aim of this study is to compare immediate and long-term obstetrical outcomes of patients who underwent cesarean delivery with and without uterine artery embolization (UAE) for the management of placenta accreta spectrum disorder.

MATERIAL AND METHODS

A retrospective case control study including all pregnant women admitted to a single tertiary medical center between December 2001 and May 2018 with a diagnosis of placenta accreta spectrum disorder, who underwent cesarean delivery with and without UAE. Groups were compared for maternal characteristics, operative management, postoperative complication rate and long-term outcomes. Follow up on future obstetrical outcomes was conducted via telephone questionnaire. Non-parametric statistics were used.

RESULTS

During the study period, 272 women met the inclusion criteria: 64 (23.53%) and 208 (76.47%) underwent preservative cesarean section with and without UAE, respectively. UAE procedure was associated with a longer operative time (82.5 [68-110] vs 50.5 [39-77] minutes; P = .001), and higher blood loss (2000 (1500-3000) vs 1000 (600-2000) mL; P = .001). Hysterectomy rate was comparable between the groups (9 [14%] vs 35 [16.82%]; P = .88); however, multivariate logistic regression analysis found UAE to be an independent factor associated with lower hysterectomy rate (P = .02). Postoperative complications were more frequent in the UAE group. Follow up was achieved in 29 (59.18%) and 72 (51.79%) of the women with and without UAE, respectively (P = .36). No differences were found in rate of abortions, pregnancy and deliveries between the groups.

CONCLUSIONS

Cesarean delivery using UAE in placenta accreta spectrum disorder is associated with a higher rate of operative and postoperative complications. Nevertheless, in cases of severe adherence of the placenta, embolization reduces the need for hysterectomy, allowing future fertility.
