Local intra-gestational sac methotrexate injection followed by dilation and curettage in treating cesarean scar pregnancy.

PURPOSE: To assess the safety and efficacy of local intra-gestational sac methotrexate injection followed by dilation and curettage (D&C) in treating cesarean scar pregnancies (CSP). METHOD: Medical records of CSP patients treated with local intra-gestational sac methotrexate injection followed by dilation and curettage were analyzed at the Maternal and Child Hospital of Guangxi Zhuang Autonomous Region, China. RESULTS: Thirty-one patients were included in this study. The mean gestational age, sac diameter and thickness of the uterine scar were 49.6 ± 7.7 days, 1.8 ± 0.6 cm and 0.30 ± 0.15 cm, respectively. The median pretreatment serum ß-human chorionic gonadotropin (ß-HCG) level was 40,887 mIU/mL, with the 25th and 75th percentiles at 19,852 and 74,552, respectively. The median blood loss during D&C was 20 mL with the 25th and 75th percentiles at 10 mL and 50 mL. Following D&C, a Foley's balloon catheter compression was implanted in 26 (83.9%) patients due to active uterine bleeding. All patients had a ß-HCG regression time of ≤ 4 weeks after D&C. While 30 patients (96.8%) had a uterine recovery time of ≤ 4 weeks, and 29 patients (93.5%) had resumption of menstruation of less than 6 weeks. Three patients (9.7%) had complications. One of them suffered from massive vaginal bleeding and underwent s blood transfusion. There were no other complications, such as pelvic infection and uterine rupture during the procedures. And no patient was converted to surgical resection or uterine artery embolization. Overall, 30 patients (96.8%) were treated successfully. CONCLUSION: Local intra-gestational sac methotrexate injection followed by D&C with the aid of a Foley's balloon catheter compression appears to be a safe and effective treatment for CSP. Further randomized controlled trials are suggested to confirm these findings.

Advances in the management of early pregnancy loss.

PURPOSE OF REVIEW: To describe recent advances in management of early pregnancy loss. RECENT FINDINGS: Addition of mifepristone to current protocols for medical management of miscarriage increases effectiveness of a single dose of misoprostol and significantly reduces subsequent aspiration procedures. Women with an incomplete evacuation after medical management may be treated expectantly with similar rates of complete expulsion compared with surgical management at 6 weeks. As cytogenetic analysis improves, analysis of products of conception can be performed whether collected after surgical or medical management and is an efficient strategy in starting a recurrent pregnancy loss work-up. For those seeking pregnancy after miscarriage, conception immediately following an early pregnancy loss is not associated with increased risk of subsequent miscarriage. However, recent studies suggest that the original intendedness of the pregnancy resulting in miscarriage does not predict future reproductive goals of the woman, so family planning should be discussed at the time of miscarriage. SUMMARY: Miscarriage is a common experience among reproductive-aged women and advances in medical management and modern-day aspiration techniques make the use of the sharp curette obsolete.

Cesarean Scar Pregnancies: A Systematic Review of Treatment Options.

The objective of this systematic review was to assess the efficacy and safety of treatment options of cesarean scar pregnancies (CSPs). We searched MEDLINE, Embase, and the Cochrane Library from inception to June 2016 as well as reference lists. We included English publications reporting treatment outcomes of at least 10 cases of CSPs. Two authors screened for eligibility, extracted data, and assessed the quality of the included studies. Treatment was considered successful if no subsequent intervention was required after the index treatment. Of the 1257 citations identified, 63 studies were eligible. The overall success rate of systemic methotrexate (MTX) and/or local injection of MTX or potassium chloride was 62%. Dilation and curettage (D&C) was associated with a 28% risk of hemorrhage that dropped to 4% when combined with uterine artery embolization (UAE). Hysteroscopic resection of CSP was unsuccessful in 12% of cases, and inadequate human chorionic gonadotropin decay was the primary indication for additional intervention. Laparoscopic, vaginal, and open excision and repair of the defect were associated with a high success rate (≥96%) and a low risk of hemorrhage (≤4%). Expectant management resulted in a 57% live birth rate, but 63% of women required hysterectomy because of placental implantation abnormalities or second trimester uterine rupture. Most studies were of low methodologic quality, and given the heterogeneity between the studies and groups, statistical comparison of treatment options was deemed inappropriate. In conclusion, the decision to allow the progression of CSPs exposes women to a high risk of life-threatening hemorrhage and hysterectomy. Medical treatment options alone are often insufficient. D&C is a reasonable option in well-selected women or when combined with UAE. The potential benefits of excision and repair of scar defect on further pregnancy outcomes need to be further assessed.

Curettage or operative hysteroscopy in the treatment of cesarean scar pregnancy.

OBJECTIVES: To compare the clinical effects of dilatation and curettage (D&C) regimen and operative hysteroscopy coupled with curettage regimen in the treatment of cesarean scar pregnancy (CSP) following preventive uterine artery embolization (UAE). MATERIALS AND METHODS: Thirty-three women were treated with D&C after UAE (group A) and 33 women were treated with operative hysteroscopy coupled with curettage after UAE (group B). The clinical outcomes of the two groups were compared. RESULTS: There was no significant difference between the two groups with respect to the success rate, the intraoperative blood loss, the hysterectomy rate, the hospitalization time, the decline of serum ß-hCG after surgery, the time of serum ß-hCG resolution, the time of vaginal bleeding after surgery, the time to CSP mass disappearance, and the subsequent intrauterine pregnancies. The hospitalization cost in group B was higher than group A. CONCLUSIONS: Both D&C and operative hysteroscopy coupled with curettage were successful in terminating a CSP. Hysteroscopy coupled with curettage regimen did not have significant advantages and good prognosis in dealing with the gestational sac type of CSP following preventive UAE compared with D&C regimen. Treatment should be individualized and several conditions must be considered.

Microwave endometrial ablation after endometrial curettage for the management of heavy menstrual bleeding.

OBJECTIVES: The aim of the present study was to evaluate the eticacy of microwave endometrial ablation after endometrial curettage, in selected patients with heavy menstrual bleeding. MATERIAL AND METHODS: Thirty-two premenopausal women with heavy menstrual bleeding underwent microwave endometrial ablation at the Department of Obstetrics and Gynecology of the University of Patras Medical School. All patients did not respond to previous medical treatment, had completed their childbearing, and did not desire future fertility. The authors chose endometrial curettage rather than hormonal pretreatment (GnRH analogs, danazol) for endometrial preparation. Posttreatment follow up protocol included physical and ultrasonographic evaluation at three, six, nine, and 12 months for the first year and yearly after. RESULTS: The authors had no cases of uterine perforation, thermal injury to adjacent organs, and infection or sepsis. During follow up, there was a gradual decrease in amenorrhea rate (90.6% - 68.8%) and in satisfaction rate (90.6% - 71.9%). Moreover during follow up, eight women underwent to total abdominal hysterectomy. Among them, seven women had uterine myomas and one woman had adenomyosis. CONCLUSIONS: Endometrial preparation with endometrial curettage seems to be a good alternative to hormonal pretreatment. It has the advantage of avoiding delays, side effects, and cost of hormonal pretreatment. Moreover, microwave endometrial ablation after endometrial curettage is successful and highly acceptable.

Evaluating success of curettage in the surgical treatment of endometrial polyps.

OBJECTIVES: To determine treatment efficacy of curettage on endometrial polyp. METHODS: The quasi-experimental pre-and-post study was conducted in 2011-12 at the gynaecology department of Imam Reza Hospital, Mashhad, Iran, and comprised patients who underwent hysteroscopy for endometrial polyp. Location, size, number and base condition of the polyps were recorded before the patient underwent curettage. Hysteroscopy was then performed and the condition of the remaining polyps was compared with initial findings. Also, the remaining polyps were resected. SPSS 13 was used for statistical analysis. RESULTS: There were 51 patients in the study with a mean age of 33.14 ± 8.19 years (range: 23-59 years)Besides, there were 82 polyps; 38(46.3%) having a narrow base, and 44(53.7%) having a wide base. The mean polyp size was 2.39 ± 2.63cm.After performing curettage, 23 (28.0%) polyps were removed completely, 39(47.6%) had size reduction, and 20(24.4%) had no change in size. Curettage could not significantly remove polyps (p < 0.001). Polyps smaller than 2cm were more likely to have been removed compared to the bigger ones (p = 0.003).Polyps with wide base were more significantly removed than those with narrow base (p < 0.001).Further, those with wide base and also smaller than 2 cm were removed more significantly than others (p < 0.001).The location of polyps had no effect on removal probability by curettage (p = 0.114). CONCLUSION: Curettage was not found to be a reliable method for endometrial polyp removal. If hysteroscopy is not accessible, the size of the polyp should be determined by vaginal sonograghy to estimate the probability of its removal by curettage.

[Vaginal impingement of uterine arteries (Zea technique) prior to cervical curettage in cervical ectopic pregnancy: three case report and literature review]. / Pinzamiento de arterias uterinas por vía vaginal previo a legrado cervical en embarazo ectópico cervical: reporte de tres casos y revisión bibliogrifica.

Cervical ectopic pregnancy is a rare and danger clinical presentation because it has high risk of massive bleeding. The incidence is reported in 1:2500 pregnancies and has high relation with a history of cervical dilatation and curettage and assisted reproductive techniques. Advances in ultrasound resolution and use of beta fraction of human chorionic gonadotropin allow early diagnosis and provide conservative treatment with decreased morbidity, mortality and fertility preservation. Various techniques have been reported associated with cervical curettage, to reduce bleeding at the implantation site. In this report three cases of cervical ectopic pregnancy managed with cervical curettage, prior vaginal impingement of uterine arteries (Zea Technique) at the Instituto Nacional de Perinatología Isidro Espinosa de los Reyes are described. The Zea technique represents an effective option in the control of obstetric hemorrhage, including patients diagnosed with cervical ectopic pregnancy in who the bleeding volume decrease after its placement. The Zea Technique is easy to apply and preserves fertility. The success of combining this technique with endocervical curettage for the management of cervical ectopic pregnancy is demonstrated. Training for performing this technique does not require highly specialized or highly complex resources since the required material is the usual every area of obstetric care.

High-intensity focused ultrasound combined with dilatation and curettage for Cesarean scar pregnancy.

We describe a new technique for the management of Cesarean scar pregnancy (CSP), high-intensity focused ultrasound (HIFU) combined with dilatation and curettage (D&C), in four patients managed at our university hospital. All four had elevated serum human chorionic gonadotropin (hCG) levels and large lesions with strong peripheral color Doppler signals, indicating possible risk of profuse bleeding, and all four women wished to preserve their fertility. HIFU was performed under local anesthesia. Success of the treatment in all four cases was indicated by complete primary evacuation of the CSP and return of serum hCG to normal levels (serum hCG < 20 mIU/mL). However, one patient in whom there was a large scar defect and placental implantation underwent laparotomy to remove the trophoblastic tissue and repair the defect, although the hCG level had already returned to normal levels. HIFU, by utilizing ultrasound energy to heat tissue at a focal point, is able to stop embryonic cardiac activity and leads to a rapid reduction in serum hCG levels. Subsequent D&C under hysteroscopic guidance enables complete removal of products of conception following the HIFU procedure.

Iliopsoas abscess: an unexpected sequela of dilation and evacuation.

OBJECTIVE: This study aimed to report the case of a patient who developed an iliopsoas abscess after a dilation and evacuation for a midtrimester fetal demise. MATERIALS AND METHODS: This is a case report of a 35-year-old woman who underwent a dilation and evacuation at 17 weeks' gestation because of a preterm premature rupture of membranes and fetal demise. Four days later, she presented with fevers, chills, malaise, and right lower back, hip, and thigh pain. Magnetic resonance imaging of the abdomen and pelvis revealed a 2.3 × 1.6-cm right iliopsoas abscess. RESULTS: The patient underwent computed tomography-guided drainage of the abscess and made an uneventful recovery after completion of an antibiotic course and physical therapy. CONCLUSIONS: An iliopsoas abscess should be considered in the differential diagnosis of any woman presenting with fevers, chills, and unilateral lower back, hip, and thigh pain in a radicular pattern after a recent dilation and evacuation.

Anaesthesia for evacuation of incomplete miscarriage.

BACKGROUND: An incomplete miscarriage occurs when all the products of conception are not expelled through the cervix. Curettage or vacuum aspiration have been used to remove retained tissues. The anaesthetic techniques used to facilitate this procedure have not been systematically evaluated in order to determine which provide better outcomes to the patients. OBJECTIVES: To assess the effects of general anaesthesia, sedation or analgesia, regional or paracervical block anaesthetic techniques, or differing regimens of these, for surgical evacuation of incomplete miscarriage. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (23 January 2012), CENTRAL (The Cochrane Library 2012, Issue 1), PubMed (1966 to 23 January 2012), EMBASE (1974 to 23 January 2012), CINAHL (1982 to 23 January 2012), LILACS (1982 to 23 January 2012) and reference lists of retrieved studies. SELECTION CRITERIA: All published and unpublished randomised controlled trials (RCTs) or cluster-RCTs comparing the use of any anaesthetic technique (defined by authors as general anaesthesia, sedation/analgesia, regional or paracervical local block (PCB) procedures) to perform surgical evacuation of an incomplete miscarriage. We excluded quasi-randomised trials and studies that were only available as abstracts. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed studies for inclusion and assessed risk of bias. Data were independently extracted and checked for accuracy. MAIN RESULTS: We included seven trials involving 800 women. The comparisons revealed a very high clinical heterogeneity. As a result of the heterogeneity in the randomisation unit, we did not combine trials but reported the individual trial results in the 'Data and analysis' section and in the text. Half of trials have unclear or high risk of bias in several domains.We did not find any trial reporting data about maternal mortality. In terms of postoperative pain, PCB does not improve the control of postoperative pain when it is compared against sedation/analgesia or versus no anaesthesia/no analgesia. In the comparison of PCB with lidocaine versus PCB with saline solution, significant differences favouring the group with lidocaine were found in one trial (moderate or severe postoperative pain) (risk ratio (RR) 0.32; 95% confidence interval (CI) 0.18 to 0.59).When opioids were used, postoperative nausea and vomiting was more frequent in two trials comparing those versus PCB. In terms of requirement of blood transfusion, two trials showed conflicting results. AUTHORS' CONCLUSIONS: Particular considerations that influence the choice of anaesthesia for this procedure such as availability, effectiveness, safety, side effects, practitioner's choice, costs and woman's preferences of each technique should continue to be used until more evidence supporting the use of one technique or another.

Sublingual misoprostol versus standard surgical care for treatment of incomplete abortion in five sub-Saharan African countries.

BACKGROUND: In low-resource settings, where abortion is highly restricted and self-induced abortions are common, access to post-abortion care (PAC) services, especially treatment of incomplete terminations, is a priority. Standard post-abortion care has involved surgical intervention but can be hard to access in these areas. Misoprostol provides an alternative to surgical intervention that could increase access to abortion care. We sought to gather additional evidence regarding the efficacy of 400 mcg of sublingual misoprostol vs. standard surgical care for treatment of incomplete abortion in the environments where need for economical non-surgical treatments may be most useful. METHODS: A total of 860 women received either sublingual misoprostol or standard surgical care for treatment of incomplete abortion in a multi-site randomized trial. Women with confirmed incomplete abortion, defined as past or present history of vaginal bleeding during pregnancy and an open cervical os, were eligible to participate. Participants returned for follow-up one week later to confirm clinical status. If abortion was incomplete at that time, women were offered an additional follow-up visit or immediate surgical evacuation. RESULTS: Both misoprostol and surgical evacuation are highly effective treatments for incomplete abortion (misoprostol: 94.4%, surgical: 100.0%). Misoprostol treatment resulted in a somewhat lower chance of success than standard surgical practice (RR = 0.90; 95% CI: 0.89-0.92). Both tolerability of side effects and women's satisfaction were similar in the two study arms. CONCLUSION: Misoprostol, much easier to provide than surgery in low-resource environments, can be used safely, successfully, and satisfactorily for treatment of incomplete abortion. Focus should shift to program implementation, including task-shifting the provision of post-abortion care to mid- and low- level providers, training and assurance of drug availability. TRIAL REGISTRATION: This study has been registered at clinicaltrials.gov as NCT00466999 and NCT01539408.

Determining the optimal fentanyl dose for dilation and curettage procedures.

AIM: This study attempted to determine an optimal dose of fentanyl, a drug frequently used in dilation and curettage (D&C) procedures, which is commonly performed as a brief outpatient intervention. METHODS: The optimal fentanyl dose was determined using Dixon's up-and-down method. The study was accomplished with a beginning fentanyl dose of 1 microg kg(-1) with a step size of 0.1 microg kg(-1) fentanyl. RESULTS: The ED50 [95% confidence interval (CI)] for fentanyl for successful anesthesia in D&C procedures was found to be 0.45 (0.35-0.55) microg kg(-1) and the ED95 value was 0.50 (0.45-0.60) microg kg(-1). CONCLUSION: This dose is considerably lower than the standard dose that is used at present, which is 1 microg kg(-1). To the best of our knowledge, the current study is the first to show that a significantly reduced dose of fentanyl can be as effective as higher doses in D&C procedures using Dixon's up-and-down method.

Surgical treatment versus expectant care in the management of incomplete miscarriage: a randomised controlled trial.

OBJECTIVES: To determine whether expectant care of incomplete miscarriages can significantly reduce the need for surgical evacuation of retained products of conception (ERPC) without increasing complications. METHODS: A randomized controlled trial conducted at the University Unit, Teaching Hospital Mahamodara, Galle. Consecutive women with uncomplicated incomplete miscarriages at < 14 weeks period of amenorrhoea (POA), admitted from 01 January to 15 July 2009 with retained products of conception (RPC) measuring 15-50 mm in the anteroposterior (AP) diameter on transvaginal sonography (TVS) were randomised to ERPC under general anaesthesia (n=80) and expectant care (n=80) groups. Both groups were reviewed after one week clinically and with TVS. The expectant care group was reviewed weekly up to four weeks unless complete expulsion of RPC was confirmed earlier. RESULTS: Age, parity, POA, socio-economic status, distance of residence from the hospital and the AP diameter of RPC at recruitment were similar in both groups. In the expectant care group, complete expulsion of RPC occurred within one week in 69%, and three patients needed ERPC. One patient in the ERPC group required a repeat ERPC. The durations of abdominal pain and the days off normal work were similar in both groups. The expectant care group had a longer duration of vaginal bleeding (p < 0.01) than the ERPC group. Complications were rare and similar in both groups and not of clinical significance. CONCLUSION: Expectant care in the management of uncomplicated first trimester incomplete miscarriage is safe and effective with no significant short-term complications.

An efficient conservative treatment modality for cervical pregnancy: angiographic uterine artery embolization followed by immediate curettage.

OBJECTIVE: We sought to evaluate a conservative treatment modality, angiographic uterine artery embolization (UAE) followed by immediate curettage, in the treatment of cervical pregnancy. STUDY DESIGN: Sixteen patients with cervical pregnancy were first treated by UAE to control or prevent vaginal bleeding. Curettage of cervical canal was performed immediately after UAE to remove gestational tissue from the cervix. Clinical outcome assessments include vaginal bleeding, serum ß-human chorionic gonadotropin level, cervical mass, menstruation, fertility, and hospitalization time. RESULTS: Fifteen patients were successfully treated by UAE followed by immediate curettage. One patient at very early gestational age underwent UAE only. Quick regression of serum human chorionic gonadotropin level and cervical mass, fertility preservation, and a short hospital stay were observed. CONCLUSION: UAE followed by immediate curettage is an efficient conservative treatment for cervical pregnancy. This procedure may become a useful alternative to other conservative approaches.

Dilatation and curettage versus lesion resection in the treatment of cesarean-scar-pregnancy: A systematic review and meta-analysis.

This meta-analysis was performed to compare the efficacy and safety of dilatation and curettage (D&C) (simply D&C or combined with other treatments) and lesion resection for cesarean scar pregnancy (CSP). A search of English and Chinese databases from 2010 to 2019 was conducted. Thirty one studies were retrieved including sixteen random controlled and fifteen case controlled trials. Compared with abdominal resection surgery(ARS) and vaginal resection surgery(VRS), uterine artery embolization(UAE)+D&C has no obvious difference in curative effect and safety (UAE + D&C versus ARS: Cure rate(CR): P = 0.076, time for menstruation recovery/ß-HCG normalization: P = 0.545/0.949,Blood loss: P = 0.005, adverse event: P = 0.420; versus VRS: CR: P = 0.085, time for menstruation recovery/ß-HCG normalization: P < 0.001/P = 0.031,Blood loss: P = 0.902, adverse event: P = 0.249). UAE + D&C associated with lower blood loss and less postoperative complication than laparoscopic resection surgery(LRS), but LRS take more advantages in terms of the curative effect (CR: P = 0.047, time for menstruation recovery/ß-HCG normalization: P = 0.352/0.103). The efficacy and safety of VRS are better than D&C, methotrexate (MTX) + D&C (D&C versus VRS: CR: P < 0.001, time for ß-HCG normalization: P = 0.363,blood loss: P < 0.001, adverse event: P = 0.046; MTX + D&C versus VRS: CR: P < 0.001, time for menstruation recovery/ß-HCG normalization: P < 0.001/P = 0.005, blood loss: P < 0.001, adverse event: P < 0.001). Lesion resection had advantages in shorter time for menstrual recovery/ß-HCG normalization and less adverse events, lower failure rate over the administration of D&C treatments. In detail, the curative effect of UAE + D&C is similar to ARS and VRS, but inferior to LRS, while the safety of UAE + D&C is better than LRS. The efficacy and safety of simply D&C and MTX + D&C are not as good as VRS.

Enhanced myometrial vascularity: case presentation and review.

OBJECTIVE: To describe the etiology of arteriovenous malformations (AVM) and enhanced myometrial vascularity (EMV), and review updates in management for patients with retained products of conception (RPOC) associated with EMV through a case presentation. DESIGN: A 6-minute narrated video discusses the recent distinction between EMV and AVM. The etiology, symptoms, imaging findings/interpretation, and management based on symptoms are reviewed in detail. As this represents a single case report, it does not meet the definition of research according to the regulations at 45 CFR 46.102(l); therefore, institutional review board approval was not required. SETTING: Tertiary referral center. PATIENT(S): Eight weeks after suction dilation and curettage (D&C) for an incomplete abortion, a 28-year-old gravida 1, para 0 patient presented to an outside facility with RPOC, menorrhagia, and an acute decrease in hemoglobin. After uterine AVM was diagnosed, she was transferred to our facility for further care. INTERVENTION(S): After transfer to our center, ultrasound demonstrated RPOC, with prominent internal vasculature containing peak systolic velocity >20 cm/s. A diagnosis of EMV was made. Magnetic resonance imaging confirmed a prominent serpentine vessel at the endometrium and RPOC within the uterine cavity (Fig. 1). Due to her anemia, she underwent uterine artery embolization (UAE) followed by suction D&C (Fig. 2). Hysteroscopy was performed before and after suction D&C and after curettage, a large vascular bundle was appreciated at the surface of the endometrium. MAIN OUTCOME MEASURE(S): None. RESULT(S): The patient presented to the clinic 2 weeks postoperatively with the resolution of abnormal uterine bleeding symptoms and a negative ß-human chorionic gonadotropin test. CONCLUSION(S): Management of patients with EMV is dependent on the extent of their symptoms. If significant bleeding is present, surgical management is required. Previous reports suggested that patients with EMV and RPOC should undergo UAE before D&C, but more recent studies suggest that D&C may be initiated without UAE, as EMV associated with RPOC may be a normal transient placentation phenomenon and have less risk of hemorrhage than previously suspected. However, in patients with significant preoperative bleeding and/or anemia, we propose that UAE should still be considered. Each patient requires individualized management based on symptoms, signs, imaging, and plans for future fertility. The ideal management of patients with RPOC and EMV remains to be determined.

Clinical efficacy analysis of different therapeutic methods in patients with cesarean scar pregnancy.

OBJECTIVE: The purpose of this study was to analyze the clinical efficacy of five therapeutic strategies in patients with CSP. MATERIALS AND METHODS: A total of 135 CSP patients were included and divided into five groups based on the treatment they received, including transvaginal resection (Group A), laparoscopic resection (Group B), uterine arterial embolization (UAE) combined with hysteroscopic curettage (Group C), UAE combined with uterine curettage (Group D), and hysteroscopic curettage (Group E). To investigate the clinical efficacy of these strategies, intraoperative bleeding, serum ß-hCG levels and recovery time, menstruation recovery time, hormone levels at 1 month after treatment. RESULTS: Patients in group A had the lowest postoperative serum ß-hCG levels, and the shortest recovery times of both serum ß-hCG and menstruation, followed by patients in group B. Group C and D had small amount of blood loss. The hospital stays and costs were low in group E. In addition, the sex hormone levels showed no significant difference among the five groups. CONCLUSION: Our results indicated that resection surgery and UAE have good curative effects, but high hospital costs in CSP treatment. The selection of an optimal treatment regimen for CSP should be carried out based on specific conditions of the patients.

Surgical procedures for evacuating incomplete miscarriage.

BACKGROUND: Incomplete miscarriage is a major problem that should be effectively managed with safe and appropriate procedures. Surgical evacuation of the uterus for management of incomplete miscarriage usually involves vacuum aspiration or sharp curettage. OBJECTIVES: To compare the safety and effectiveness of surgical uterine evacuation methods for management of incomplete miscarriage. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (July 2010). SELECTION CRITERIA: Randomized trials where different surgical methods were used to manage incomplete miscarriage were eligible for inclusion. DATA COLLECTION AND ANALYSIS: We extracted population characteristics, settings, and exclusion criteria, in addition to outcomes such as complications of the procedure, duration, need for re-evacuation, blood transfusion, and analgesia/anesthesia. MAIN RESULTS: Two trials (involving 550 women) were included. Vacuum aspiration was associated with statistically significantly decreased blood loss (mean difference (MD) -17.10 ml, 95% confidence interval (CI) -24.05 to -10.15 ml), less pain during the procedure (risk ratio (RR) 0.74, 95% CI 0.61 to 0.90), and shorter duration of the procedure (MD -1.20 minutes, 95% CI -1.53 to -0.87 minutes), than sharp metal curettage, in the single study that evaluated these outcomes in 357 women. Serious complications such as uterine perforation and other morbidity were rare and the sample sizes of the trials were not large enough to evaluate small or moderate differences. AUTHORS' CONCLUSIONS: Although the review indicates that vacuum aspiration is safe, quick to perform, and less painful than sharp curettage, and should be recommended for use in the management of incomplete miscarriage, the results are based on data from only one study. Analgesia and sedation should be provided as necessary for the procedure.
