AIM
In Japan, dilatation and curettage (D&C) is a common procedure for spontaneous miscarriage and induced abortion, and its safety has long been an issue. Electric vacuum aspiration (EVA) is also common, but manual vacuum aspiration (MVA) was introduced recently, with medical abortions using mifepristone or misoprostol which are not yet legally accepted. This nationwide retrospective study surveyed the surgical methods and complications associated with spontaneous miscarriage and induced abortion at less than 12 weeks of gestation in Japan to assess their safety, in comparison with a similar survey for induced abortions in 2012.
METHODS
Questionnaires were sent to 4176 facilities with a license for induced abortion surgeries in 2019. The questions included were the methods used, number of spontaneous miscarriages and induced abortions, and number of complications (uterine perforation, incomplete abortion, and gross bleeding requiring blood transfusion).
RESULTS
Responses were received from 1706 facilities (40.9%). Although EVA with sharp curettage was the most common surgical method, which was used for 11 953 spontaneous miscarriages (28.9%) and 24 045 induced abortions (37.3%), the most common surgical method per facility was D&C, and the rates of D&C for spontaneous miscarriages (38.4%) and induced abortions (44.7%) performed in general hospitals were significantly higher than those in clinics (24.1% and 22.0%, respectively). There was no significant difference in the complication incidence rate among surgical methods for spontaneous miscarriages. However, in induced abortion surgery, the total complication and incomplete abortion incidence rates for D&C were significantly higher than those for EVA without sharp curettage (47/15 162 [0.31%] vs. 29/18 693 [0.16%], p = 0.00362, 45/15 162 [0.30%] vs. 27/18 693 [0.14%], p = 0.00285, respectively). There was no significant difference in the complication incidence rate between MVA and other surgical methods for each abortion surgery.
CONCLUSION
In Japan, especially in general hospitals, D&C is still widely used for miscarriage and induced abortion surgery. Its complication-incidence rates significantly decreased compared with that of the nationwide survey in 2012, but were still significantly higher than EVA without sharp curettage. Few facilities used MVA, but its complication rate was comparable with those of other surgical methods.

OBJECTIVE
The culture failure rate of conventional karyotyping in products of conception evacuated from early pregnancy loss by traditional electrical vacuum aspiration and/or dilation & curettage remains high. We aim to determine whether obtaining products of conception from early pregnancy loss via another evacuation approach, ultrasound-guided manual vacuum aspiration, could decrease the culture failure rate of karyotyping.
METHODS
For patients with early pregnancy loss, ultrasound-guided manual vacuum aspiration (Case group) and traditional electrical vacuum aspiration and/or dilation & curettage (Control group) were applied as surgical methods for pregnancy loss management respectively. The evacuated products of conception were subjected to cytogenetic karyotyping analysis. The primary outcome was the culture failure rate of karyotyping. Secondary outcomes included the chromosomal abnormality spectrum, maternal cell contamination, and complications from the manual vacuum aspiration procedure.
RESULTS
For the case group, 132 products of conception were genetically analyzed by conventional karyotyping. The culture failure rate was significantly lower than that of the control cohort (2.3% vs 7.4%, p = 0.027). 65.2% of cases were abnormal within the detection scope of karyotyping. The euploid female to male ratio was 0.82 (18:22), suggesting a lower likelihood of maternal cell contamination. The efficacy in achieving complete evacuation was 99.6%. There were no significant complications from the procedure.
CONCLUSION
Ultrasound-guided manual vacuum aspiration approach significantly decreased the culture failure rate of karyotyping and decreased maternal cell contamination tendency, enabling a high and accurate cytogenetic diagnosis. It is especially crucial when the cytogenetic analysis is required in the early pregnancy loss clinics.

The Journal of Obstetrics and... Apr 2021To evaluate the risk factors and incidence of Asherman Syndrome in women with post-abortion uterine evacuation and curettage.
AIM
To evaluate the risk factors and incidence of Asherman Syndrome in women with post-abortion uterine evacuation and curettage.
METHODS
A total of 2546 patients who had surgical abortion (uterine evacuation and curettage) before the 20th gestational week with indications of missed abortion, anembryonic pregnancy, incomplete abortion, and elective curettage in a tertiary antenatal care center were recruited. The patients were called and surveyed for their symptoms; including infertility, oligo-amenorrhea and recurrent pregnancy loss, preterm birth and intrauterine growth retardation and abnormal placentation as criteria of Asherman Syndrome. Diagnostic (office) hysteroscopy was performed for 177 who had one of those complaints.
RESULTS
The incidence of Asherman Syndrome was 1.6% (n = 43/2546). History of ≥3 abortions was the main factor that increased the risk of Asherman Syndrome for by 4.6 times. Use of vacuum aspiration or sharp curettage, premedication for cervical priming, and having a pregnancy >10th gestational weeks were not risk factors for Asherman Syndrome.
CONCLUSION
When the diagnosis was based on presence of symptoms who underwent uterine instrumentation, the incidence of Asherman Syndrome was found to be 1.6%. Repeated abortions were the main risk factor for Asherman Syndrome and avoiding from repeated uterine instrumentations may have a role in prevention.

Comparative Study
BACKGROUND
Nepal government has legalized abortion and approved both medical abortion and manual vacuum aspiration for first trimester pregnancy. However, there is inadequate evidence in our setup to comment on the acceptability and complications of medical abortion and manual vacuum aspiration for termination of pregnancy up to nine weeks of gestation. The objective of this study is to compare the reasons for termination of pregnancy, effectiveness and complications between medical abortion and manual vacuum aspiration in termination of pregnancy up to nine weeks.
METHODS
A comparative study was conducted among women requesting termination of pregnancy up to nine weeks of gestation in Comprehensive Abortion Care unit of Paropakar Maternity and Women's Hospital. Women were kept in medical abortion and manual vacuum aspiration groups after they chose the method. They were advised for follow up in two weeks. Reasons for termination, effectiveness and complications of medical abortion and manual vacuum aspiration were compared using Chi square test.
RESULTS
In a total of 160 women, the most common reason for termination of pregnancy was completion of the family. In manual vacuum aspiration group 43 (58.9%) women had minimal per vaginal bleeding while 30 (40.54%) women in medical abortion group had per vaginal bleeding for 6-10 days(p less than 0.001). Rate of complete abortion in medical abortion group was 85.14% (n=63) and in manual vacuum aspiration group was 93.15% (n=68).
CONCLUSIONS
The complications following medical abortion were higher than manual vacuum aspiration in termination of pregnancy up to nine weeks. Rate of completeness of abortion following manual vacuum aspiration is superior over medical abortion.

BACKGROUND
Transcatheter aspiration is utilized for removal of thrombi and vegetations in inoperable patients and high-risk surgical candidates where medical therapy alone is unlikely to achieve desired outcome. A number of case reports and series have been published since the introduction of AngioVac system (AngioDynamics Inc., Latham, NY) in 2012 where this technology was used in the treatment of endocarditis. However, there is a lack of consolidated data reporting on patient selection, safety and outcomes.
METHODS
PubMed and Google Scholar databases were queried for publications reporting cases where transcatheter aspiration was used for endocarditis vegetation debulking or removal. Data on patient characteristics, outcomes and complications from select reports were extracted and systematically reviewed.
RESULTS
Data from 11 publications with 232 patients were included in the final analyses. Of these, 124 had lead vegetation aspiration, 105 had valvular vegetation aspiration, and 3 had both lead as well as valvular vegetation aspiration. Among the 105 valvular endocarditis cases, 102 (97 %) patients had right sided vegetation removal. Patients with valvular endocarditis were younger (mean age 35 years) vs. patients with lead vegetations (mean age 66 years). Among the valvular endocarditis cases, there was a 50-85 % reduction in vegetation size, 14 % had worsening valvular regurgitation, 8 % had persistent bacteremia and 37 % required blood transfusion. Surgical valve repair or replacement was subsequently performed in 3 % and in-hospital mortality was 11 %. Among patients with lead infection, procedural success rate was reported at 86 %, 2 % had vascular complications and in-hospital mortality was 6 %. Persistent bacteremia, renal failure requiring hemodialysis, and clinically significant pulmonary embolism occurred in about 1 % each.
CONCLUSIONS
Transcatheter aspiration of vegetations in infective endocarditis has acceptable success rates in vegetation debulking as well as rates of morbidity or mortality. Large prospective multi-center studies are warranted to determine predictors of complications, thus helping identify suitable patients.

Contraception Sep 2022To evaluate whether administration of intranasal fentanyl reduces reported pain during first-trimester uterine aspiration. (Randomized Controlled Trial)
Randomized Controlled Trial
OBJECTIVE
To evaluate whether administration of intranasal fentanyl reduces reported pain during first-trimester uterine aspiration.
STUDY DESIGN
We conducted a multicenter, randomized, double-blind, placebo-controlled trial of patients with pregnancies less than or equal to 14 weeks gestation seeking uterine aspiration for induced abortion, early pregnancy loss, or failed medication abortion. We randomized participants 1:1 to either intranasal fentanyl 100 mcg or intranasal placebo. All participants received ibuprofen and a standardized paracervical block. The primary outcome was pain indicated at the time of uterine aspiration on a 100 mm visual analog scale (VAS). We designed the study to detect a 15 mm difference in mean pain scores, which required 53 people in each arm for a total of 106 participants. Secondary outcomes included postprocedure pain and patient satisfaction with pain control.
RESULTS
From March 2017 through June 2018, we screened 355 people for eligibility and enrolled 107 participants. Those who received intranasal fentanyl reported similar uterine aspiration pain to participants who received placebo (58.4 ± 28.0 fentanyl vs 58.6 ± 24.5 placebo, p = 0.97). Participants who received intranasal fentanyl also reported similar postprocedure pain scores compared to participants who received placebo (19.1 ± 19.4 fentanyl vs 17.2 ± 19 placebo, p = 0.63), and were equally satisfied with procedure pain control (66.8 ± 31.2 fentanyl vs 63.3 ± 29.2 placebo, p = 0.57).
CONCLUSION
Intranasal fentanyl did not decrease reported pain with first-trimester uterine aspiration, nor did it decrease postprocedure pain compared to placebo. As an adjunct to ibuprofen and paracervical block, intranasal fentanyl did not improve patient satisfaction with pain control.
IMPLICATIONS
Intranasal fentanyl does not reduce reported pain with first-trimester uterine aspiration, however abortion-seeking patients are amenable to receiving intranasal medications for pain management.

Review
Latin America hosts the most restrictive abortion legislation globally. In 2007, Mexico, the second largest Catholic country in the world, decriminalized elective abortion within the first twelve weeks of pregnancy in the capital: Mexico City (also known as Federal District of Mexico). Following the reform, the Mexico City Ministry of Health (MX-MOH) implemented safe and legal services. Free services are provided to Mexico City residents and a sliding fee of up to $100 is applied to women from other Mexican states. Conscientious objection (CO) was addressed and included in service provision guidelines. Since 2007, 18 of 32 states amended their penal codes to restrict abortion. The road toward increasing access to abortion services at the MX-MOH included a shift from dilation and curettage (D&C) to medical abortion (MA), first with the misoprostol-alone regimen, followed by the combined mifepristone-misoprostol regimen. Manual vacuum aspiration is offered to out-of-state-women or to those beyond the gestational age where MA is less effective. Contraceptive uptake among abortion seekers is high (up to 95% of them prefer a free method of their choice). The Legal Interruption of Pregnancy program at the MX-MOH continues to provide effective, safe, reliable, and free services. However, women from indigenous groups residing in rural areas, those with low schooling, and adolescents with an unintended pregnancy who live in rural, urban, peri-urban districts, and at the state level are underserved despite being legally eligible to receive abortion services. Therefore, information and services for the disadvantaged groups need to be strengthened.

BACKGROUND
Cesarean scar pregnancy (CSP), a rare iatrogenic form of ectopic pregnancy (EP), cause of severe maternal morbidity. Each subtype of CSP needs different treatment and there is no consensus about this topic. Despite improvements, the lack of universally accepted therapeutic management and discordance present in literature indicates that treatment has been mainly based on experiences reported.
METHODS
A case series of our double combined approach with methotrexate (MTX) administration followed by vacuum aspiration or resectoscopic approach was reported, with an overview of literature. Eleven patients with CSP underwent a double-step treatment: systemic MTX therapy followed by vacuum aspiration or by resectoscopy, if the gestational sac was embedded deeply in myometrium. For CSP type 1, according to Delphi sonographic classification, with minor potentially risk of complications with a myometrial thickness >3.5 mm, we preferred to adopt vacuum aspiration, while type 2-3 of CSP and myometrial thickness ≤3.5mm were managed with resectoscopy.
RESULTS
The average gestational age was 59.1±7.22 days. On the seventh day after MTX administration, the serum β hCG levels decreased in 80% of all patients. After the MTX injection, the CSP mass did not disappear in any patient. MTX therapy was followed by vacuum aspiration in six and by resectoscopy in five cases. In one case bleeding was controlled by Foley balloon treated with vacuum. In type II-III, CSP was performed UAE (uterine artery embolization) followed by resectoscopy procedure.
CONCLUSIONS
Compared with the results in previous studies, MTX administration followed by suction curettage was more effective than dilatation and curettage and systemic MTX in treatment of CSP. We consider very useful this procedure in case of slow absorption and when the camera was embedded deeply in myometrium (CSP2-3), because that hysteroscopy evaluation of uterine cavity under direct vision is highly accurate in identifying the real cleavage of the gestational camera. We have only used vacuum aspiration in CSP type 1 for minor risk of bleeding.

INTRODUCTION
Manual vacuum aspiration is increasingly accepted as an alternative to medical or surgical evacuation of the uterus after first-trimester miscarriage. This study aimed to assess the efficacy of ultrasound-guided manual vacuum aspiration (USG-MVA) in the management of first-trimester miscarriage.
METHODS
This retrospective analysis included adult women with first-trimester miscarriage who underwent USG-MVA in Hong Kong between July 2015 and February 2021. The primary outcome was the efficacy of USG-MVA in terms of complete evacuation of the uterus, without the need for further medical or surgical intervention. Secondary outcomes included tolerance of the entire procedure, the success rate of karyotyping using chorionic villi, and procedural safety (ie, any clinically significant complications).
RESULTS
In total, 331 patients were scheduled to undergo USG-MVA for first-trimester miscarriage or incomplete miscarriage. The procedure was completed in 314 patients and well-tolerated in all of those patients. The complete evacuation rate was 94.6% (297/314), which is similar to the rate (98.1%) achieved by conventional surgical evacuation in a previous randomised controlled trial in our unit. There were no major complications. Samples from 95.2% of patients were suitable for karyotyping, which is considerably higher than the rate of suitable samples (82.9%) obtained via conventional surgical evacuation in our previous randomised controlled trial.
CONCLUSION
Ultrasound-guided manual vacuum aspiration is a safe and effective method to manage first-trimester miscarriage. Although it currently is not extensively used in Hong Kong, its broader clinical application could avoid general anaesthesia and shorten hospital stay.

INTRODUCTION
Manual vacuum aspiration (MVA) is a safe and effective alternative option for the management of first-trimester miscarriage, termination of pregnancy, or retained pregnancy tissue. Ireland's first MVA clinic was set up in the Rotunda Hospital in April 2020.
OBJECTIVE
To identify the number of women who have undergone MVA since establishing our service, to assess the efficacy and safety of MVA in that service, and to develop local Irish studies that further support the safety of MVA, adding to the international body of evidence.
METHODS
With the approval and assistance of the Clinical Audit Committee, we obtained a log of all patients who underwent MVA in the first 18 months of the service. We performed a retrospective electronic chart review using Maternal and Newborn Clinical Management System. We collected the data and preformed a descriptive analysis.
RESULTS
In total, 86 women underwent MVA, 85 (98.8%) of which were successfully completed. There were no immediate procedural complications, inter-hospital transfers, or emergency electric vacuum aspiration (EVA) required. We obtained an incomplete evacuation rate of 4.7% (n = 4).
CONCLUSION
We have demonstrated that the MVA service in the Rotunda Hospital is a safe, effective management option with advantages for both the patient and the healthcare system. We recommend consideration for provision of funding and resources to enable expansion of this service nationally in order to give women greater autonomy of choice in the management of early pregnancy complications and termination of pregnancy.
