Background The World Health Organization does not recommend dilatation and sharp curettage (D&C) for the surgical treatment of miscarriage during the first trimester because this may cause Asherman’s syndrome due to endometrial damage; therefore, suction remains the primary treatment option. While manual vacuum aspiration (MVA) has been widely used since the 1990s outside Japan, the use of an MVA device (Women’s MVA system) was approved in Japan in October 2015. Here, we examined the efficacy of the MVA kit in women surgically treated for miscarriage. Methods This retrospective cohort study was conducted between 2014 and 2018 at the International University of Health and Welfare Hospital in Japan. Women who underwent surgical treatment for miscarriage within 12 weeks of pregnancy were identified and enrolled in the study. A total of 404 women were included who underwent the following procedures: 121 D&C, 123 electric vacuum aspiration (EVA), and 160 MVA. For each participant, the duration of surgery, amount of bleeding, amount of anesthetic used, incomplete abortion requiring repeat procedures, and intraoperative/postoperative complications were evaluated. Results The duration of surgery was 13.7 ± 7.2, 11.2 ± 4.2, and 6.9 ± 4.3 min in the D&C, EVA, and MVA groups, respectively (p = 1.00). The amount of anesthetic used was not significantly different among all groups. Bleeding of ≥ 100 mL was confirmed in three (2.4%), one (0.8%), and one (0.6%) patient(s) in the D&C, EVA, and MVA groups, respectively (p = 0.50). Incomplete abortion was identified in three (2.4%), two (1.6%), and one (0.6%) patient(s) in the D&C, EVA, and MVA groups, respectively (p = 0.61). However, severe intraoperative/postoperative complications were not observed in any group. Conclusions Surgical treatment for miscarriage performed using the MVA kit has safety and efficacy similar to those of conventional methods, such as D&C and EVA.
Case series Patient:— Final Diagnosis: Acute fatty liver of pregnancy • HELLP syndrome Symptoms: Decrease in insulin dosage for gestational diabetes mellitus Medication: — Clinical Procedure:— Specialty: Obstetrics and Gynecology Objective: Unusual clinical course Background: When a woman becomes pregnant, the placenta produces human placental lactogen (hPL). The anti-insulin effect of hPL raises maternal blood glucose levels, allowing the fetus to use glucose as a nutrient. Because hPL is produced by the placenta until delivery, insulin requirements in patients with gestational diabetes mellitus (GDM) typically increase, but in some cases, they may decrease. We retrospectively examined data from women with GDM who received insulin and delivered at our hospital. Case Reports: From April 2019 to March 2020, we targeted patients who were diagnosed with GDM, received insulin, and delivered at our hospital. GDM was diagnosed based on the guidelines from the Japanese Society of Obstetrics and Gynecology. The rate of change in insulin dosage was calculated as: (insulin dosage at delivery – insulin dosage 14 days before delivery) divided by 14. Two patients whose insulin dosage was significantly reduced developed a syndrome of hemolysis, elevated liver enzymes, and low platelet count or acute fatty liver of pregnancy and underwent emergency cesarean section. Conclusions: The present case report suggests that a decrease in insulin requirement in pregnant patients with GDM can predict maternal abnormalities due to placental dysfunction.
The effect of twin gestation on carbohydrate metabolism was evaluated using a 75 g oral glucose tolerance test (75 g OGTT). A 75 g OGTT was performed in 63 twin gestations and 3 791 singleton gestations during the third trimester. Plasma glucose concentrations were measured in the pregnant women under fasting conditions as well as 30 min, 1 h, and 2 h after ingestion of glucose (75 g oral load), and serum insulin concentrations were measured in fasting and 30 min post-ingestion samples. Women with twin gestations showed significantly lower plasma glucose concentrations during fasting and 30 min after the glucose load in the samples taken than those with singleton gestations. No significant difference in serum glucose concentrations was found in the other specimens. There were no cases of gestational diabetes mellitus in our study. Although women with twin gestations demonstrated lower plasma glucose concentrations than women with singleton gestations, the difference observed was subtle. We could not find any significant differences in these plasma glucose values as used to define a pathologic OGTT between twin and singleton pregnancies, with the exception of the fasting value.
Background In Japan, dilatation & curettage (D&C) has been performed under general anesthesia as a surgery for an early pregnancy miscarriage for a long time. In 2016, manual vacuum aspiration (MVA) under general anesthesia was introduced at our hospital and has been used as a surgical treatment for first-trimester pregnancy miscarriage, with its utility to date being reported here. In July 2018, our hospital introduced the MVA procedure under local anesthesia. In this study, we evaluated the efficacy and safety of MVA under general and local anesthesia in first-trimester pregnancy miscarriage surgery in Japanese women. Methods In this retrospective observational cohort study, we enrolled 322 pregnant women at less than 12 weeks of gestation, who underwent MVA surgery under local anesthesia (n = 166) or conventional general anesthesia (n = 156). The duration of surgery, blood loss volume, quantity of anesthesia, presence or absence of retained products of conception, and clinical complications were evaluated. In addition, the intraoperative pain and treatment satisfaction were assessed using the visual analog scale (VAS). Results The duration of surgery was significantly shorter in the local anesthesia group. No significant differences were observed between both groups in terms of the blood loss volume and incidence of retained products of conception. In addition, no serious complications were observed in either group. No significant differences were noted between the two groups in the VAS scores for pain and treatment satisfaction. Conclusions In this retrospective study, the use of MVA under local anesthesia for early pregnancy miscarriage surgery was found to be equally safe and effective when performed under conventional general anesthesia. This technique allowed the achievement of appropriate pain control with excellent patient satisfaction.
