Favorable outcome following emergency second trimester cerclage.

BACKGROUND: To evaluate the outcome of midtrimester emergency cerclage with or without bulging of membranes. METHODS: A retrospective cohort study of 99 women who underwent emergency second trimester cerclage (16-27 gestational weeks). In 75 women the cervix was dilated and effaced but without bulging of membranes (group 1), and in 24 women the dilation and effacement of the cervix were accompanied by bulging of membranes into the vagina in an hourglass formation (group 2). McDonald technique was applied in all patients. RESULTS: Prolongation of pregnancy was significantly longer in group 1 compared to group 2 (14.3+/-6.5 vs 9.3+/-4.8 weeks, p=0.007). The mean gestational age at delivery was significantly higher in group 1 compared to group 2 (34.6+/-4.6 vs 29.5+/-3.2 weeks, p=0.001). The incidence of chorioamnionitis was higher in group 2 compared to group 1 but statistically insignificant (25% vs 15%, p=0.2). The overall neonatal survival was 83% (82 out of 99 neonates), without statistical difference between the two groups (86% in group 1 and 71% in group 2, p=0.2). CONCLUSIONS: Favorable neonatal outcome may be accomplished in patients with cervical incompetence in the second trimester of pregnancy following cervical emergency suturing even performed when the membranes are bulging through the cervix into the vagina.

Intra-uterine fluid collection in postmenopuasal women with cervical stenosis.

OBJECTIVES: The aim of the study was to assess the clinical significance of intra-uterine fluid collection in postmenopausal women with cervical stenosis with and without vaginal bleeding. METHODS: A group of 82 consecutive postmenopausal women with cervical stenosis and sonographically confirmed intra-uterine fluid collection underwent D&C with or without hysteroscopy. Diagnostic hysteroscopy was performed in all patients with an endometrial thickness (ET) was greater than 8mm, or with irregular endometrium at any degree of ET. The patients were divided and evaluated prospectively into two groups according to the presence or absence of postmenopausal bleeding (PMB). Twenty-six women were with PMB and 56 women were asymptomatic. RESULTS: The groups were similar as far as endometrial thickness and histopathological results were concerned. Atrophic endometrium was found in 69 patients (84%), 23 in the PMB group (89%) and 46 in the other group (82%), proliferative endometrium in 7 (9%) and endometrial polyps were found in 35 patients (43%), 12 in the PMB group (46%) and 23 in the other group (41%). When ET was > or =8 mm, in 93% of the cases an endometrial polyp was found (25 out of 27). No case of endometrial cancer was found. A premalignant condition was diagnosed in one patient with an endometrial polyp in the PMB group. All patients with endometrial thickness of less than 3 mm in ultrasound had atrophic endometrium. The incidence of intrauterine pathology increased with the increasing thickness of endometrium as observed by ultrasound. CONCLUSIONS: The presence of intra-uterine fluid collection in postmenopausal patients with cervical stenosis seems to be a benign condition. Normal endometrium of less than 3mm observed by ultrasound in postmenopausal women without vaginal bleeding does not necessarily need further surgical investigation.

Transvaginal ultrasound after first-trimester uterine evacuation reduces the incidence of retained products of conception.

OBJECTIVE: To assess the incidence of retained products of conception (RPOC) in relation to transvaginal ultrasound performed after first-trimester uterine evacuation. METHODS: This was a prospective randomized study involving 809 women undergoing first-trimester uterine evacuation. The study group included 404 women in whom transvaginal sonography was performed at the end of the surgical procedure and the control group contained 405 women who did not undergo ultrasound examination. Initially, in the study group, recurettage was immediately performed if the endometrium appeared irregular but latterly only if endometrial thickness was > or = 8 mm. The patients were followed up by gynecological and ultrasound examinations 5-8 days following the surgical procedure. RESULTS: The total complication rate was 4.3%. RPOC presented in three women in the study group (0.7%) and in 15 women in the control group (3.7%, P < 0.05). Vaginal bleeding requiring hospitalization occurred in two women in the study group (0.5%) vs. seven in the control group (1.7%, P = 0.2). Endometritis was diagnosed in one woman in the study group (0.2%) vs. six in the control group (1.5%) and uterine perforation occurred in one woman in the control group vs. none in the study group. There were no cases of RPOC in women who had an endometrial thickness of < 8 mm as demonstrated by ultrasound at the end of the surgical procedure. CONCLUSION: Transvaginal sonography immediately following first-trimester uterine evacuation may reduce the incidence of RPOC and the total complication rate. When the endometrial thickness is > or = 8 mm at the end of suction curettage, an attempt at re-evacuation of the uterine cavity is indicated.

Reproductive performance following midtrimester termination of pregnancy.

The aim of the study was to determine the impact of midtrimester abortion with extra-amniotic PGE(2) on future fertility and reproduction. Two hundred and fifteen women were enrolled. The mean induction-to-abortion interval was 21.3 h. The complication rate was 11.7%. Twenty women (9.3%) were lost to follow-up, 82 patients (38.1%) used contraception. Spontaneous pregnancy occurred in 110 out of 113 women who desired fertility (97%). Three patients were defined as infertile but conceived following treatment. The average time between the abortion and the next conception was 15.9 months (range 1-77 months). Seventy patients (63.7%) delivered at term. Premature delivery occurred in 18 patients (16.4%). Eighteen women aborted spontaneously in the first and 3 in the second trimester. One extrauterine pregnancy occurred. Second-trimester abortion with extra-amniotic PGE(2) is a safe procedure with a low rate of complication. Apparently it does not affect future fertility, but may be associated with an increased rate of premature deliveries in future gestations.

The minilaparoscope as a tool for localization and preparation for cannula insertion in patients with multiple previous abdominal incisions or umbilical hernia.

STUDY OBJECTIVE: To access a method that attempts to reduce the risk of bowel and blood vessel trauma in entry-risk patients during laparoscopy. DESIGN: Three-year observational study (Canadian Task Force classification II-2). SETTING: Tertiary university hospital. PATIENTS: Thirty-one women defined as entry-risk due to previous multiple abdominal surgeries or repair of umbilical hernia. INTERVENTION: Laparoscopy performed with a 2 mm minilaparoscope inserted at Palmer's point, a midclavicular position under the lower left rib. MEASUREMENTS AND MAIN RESULTS: In most cases the minilaparoscope was used to inspect the anterior abdominal wall for adhesions. When a location free from adhesions was seen or created by adhesiolysis, the 5- or 10-mm cannula was inserted, followed by the laparoscope. Periumbilical adhesions were more common after previous longitudinal incisions. There were no complications. CONCLUSIONS: Minilaparoscopy is safe and effective for identifying and preparing a proper cannula insertion point. This may be useful for avoiding bowel or other cannula-related trauma in women at high risk for such a complication.

Pregnancy outcome after laparoscopy or laparotomy in pregnancy.

STUDY OBJECTIVE: To assess obstetric performance and fetal outcomes after laparoscopy or laparotomy performed during pregnancy. DESIGN: Nationwide, multicenter, retrospective chart review (Canadian Task Force classification II-2). SETTING: Seventeen hospitals throughout Israel: 12 university or university-affiliated hospitals and 5 general hospitals. PATIENTS: Three hundred eighty-nine pregnant women. INTERVENTION: Laparoscopy or laparotomy for various indications. MEASUREMENTS AND MAIN RESULTS: Of 192 laparoscopies performed, 141 were during the first, 46 during the second, and 5 during the third trimester; respective figures for 197 laparotomies were 63, 110, and 24. No intraoperative complications were reported for either procedure. Six and 25 women had complications after laparoscopy and laparotomy, respectively. There was no significant difference in abortion rates between groups. Mean gestational age at delivery and mean birthweight were comparable between groups. No significant difference was found in frequency of fetal anomalies between groups or when compared with the Israel register of anomalies. CONCLUSION: Operative laparoscopy seems to be as safe as laparotomy in pregnancy.

Successful control of an Acinetobacter baumannii outbreak in a neonatal intensive care unit.

We describe an outbreak of Acinetobacter baumannii in a neonatal intensive care unit (NICU), and our investigation to determine the source and mode of transmission and identify the population at risk. A case (infected infant) was defined as a patient hospitalized in the NICU during the outbreak period, with clinical signs of sepsis and isolation of A. baumannii. In colonized infants, A. baumannii was isolated from body surfaces without signs of infection. Infected infants were separated and treated by a different medical team. Cultures were taken from working surfaces and along the infant's admission passage from the delivery room to the NICU. The outbreak strain was identified by pulsed-field gel electrophoresis (PFGE). Nine cases and eight colonized infants met the definition criteria. Cases were younger than colonized infants with regard to gestational age and age of diagnosis and had lower birthweights (P<0.01). The outbreak strain was only isolated from hygroscopic bandages used on skin under the ventilation tube and umbilical catheters. Discontinuing the use of the bandages put an end to the outbreak. We conclude that a rapid and thorough investigation of the environment during an outbreak of A. baumannii is essential to finding the source of the infection, and that hygroscopic bandages may be a source of such outbreaks.

Extra-amniotic prostaglandin E2 for midtrimester termination of pregnancy in live fetuses vs. fetal demise.

This study compared the course of midtrimester termination of pregnancies with fetal demise and those with a viable fetuses by extra-amniotic prostaglandin (PG) E(2). A total of 275 women who underwent second trimester abortion with extra-amniotic PGE2(2) were divided into two groups: 95 patients (35%) with fetal demise and 180 women (65%) with a live fetuses. Extra-amniotic PGE2(2) was administered in doses of 200 micro g every 2 h up to 20 doses. Bumm curettage was performed in the majority of the patients. We compared the duration and complication rate between the groups. The median induction to abortion interval was significantly shorter in the fetal demise group (13 vs. 21 h) than in the live fetus group. Mean gestational ages and complication rates were similar. Midtrimester termination of pregnancy with extra-amniotic PGE2(2) is a safe method with a low complication rate. In cases of pregnancy with fetal demise extra-amniotic PGE2(2) is associated with a significantly shorter induction to abortion interval than with a live fetus.

Conversion of laparoscopy to laparotomy due to adnexal malignancy.

PURPOSE: The purpose of the present report was to assess the conversion rate from laparoscopy to laparotomy due to adnexal malignancy and to identify factors that might assist in the selection of the appropriate operative approach in patients with suspicious adnexal masses. METHODS: A retrospective review of the medical records of women who underwent laparoscopy due to ultrasonically complex adnexal masses. Ninety-five consecutive patients fulfilling these criteria, were identified. A comparison of patients with benign tumors who had laparoscopy only to those with invasive malignancies in whom laparoscopy was converted to laparotomy was performed. RESULTS: Malignancy was diagnosed in 18 (18.9%) patients. In 13 patients with malignancy (two borderline and 11 invasive), comprising 72.2% of the malignancies and 13.7% of the total group with complex adnexal masses, the laparoscopy was converted to laparotomy. Age of more than 50 years and a serum CA125 level above 35 U/ml were significantly more common in the malignant than in the benign group (90.9% vs. 15.6% and 63.6% vs. 11.6%, respectively; p < 0.0001 and p < 0.003, respectively). When both factors were present, the sensitivity and specificity for malignancy were 73.3% and 93.2%, respectively, and the positive and negative predictive values 73.3% and 95.6%, respectively. CONCLUSION: When an ultrasonically complex adnexal mass is encountered, predictive factors for malignancy should be taken into account before the mode of intervention is chosen. The conversion from laparoscopy to laparotomy because of an invasive malignant tumor is acceptable, if it is performed immediately and a gynecologic oncologist is on stand-by.

Methotrexate versus hyperosomolar glucose in the treatment of extrauterine pregnancy.

The aim of this prospective, randomized, double blind study was to compare the efficacy of methotrexate and hyperosmolar glucose injected directly into the extra-uterine gestational sac under laparoscopic vision. The study included twenty women with ectopic pregnancy. Inclusion criteria were intact tubal pregnancy, not exceeding 4 cm in diameter, rising or plateauing betahCG levels, and no evidence of intra-abdominal bleeding. The patients were treated by laparoscopically guided injection of 3 mL fluid into the area containing the tubal pregnancy. The fluid contained either 25 mg methotrexate (n=9) or 50% glucose (n=9). Daily decrease in betahCG levels was faster in patients treated by methotrexate (median 8.7%) than in those treated by hyperosmolar glucose (median 4.8%), p=0.17. The study was discontinued due to a higher failure rate in the group treated by hyperosmolar glucose. In conclusion, local injection of methotrexate is superior to hyperosmolar glucose. It can be used as an alternative to salpingostomy or salpingotomy whenever laparoscopy is performed for the diagnosis and treatment of extra-uterine pregnancy.

Three conservative approaches to treatment of interstitial pregnancy.

Interstitial pregnancy is among the most dangerous types of ectopic pregnancy. Four such pregnancies in three women were treated by three conservative modalities with favorable results. A 10-week interstitial pregnancy was successfully treated by laparoscopic-guided local methotrexate (MTX) injection into the gestational sac. Six years later the same woman had a repeat unruptured interstitial pregnancy at 9 weeks' gestation, with the gestational sac located in the same location as the previous one. Laparoscopic cornuostomy was performed. An asymptomatic woman in the eighth week of an interstitial pregnancy was treated with systemic MTX, but despite decreasing beta-human chorionic gonadotropin levels, cornual rupture occurred. The patient was successfully treated by laparoscopic cornuostomy. The final patient was admitted in hypovolemic shock and hemoperitoneum and was treated successfully for ruptured 8-week interstitial pregnancy by laparoscopic cornuostomy.

Bipolar electrical energy in physiologic solution--a revolution in operative hysteroscopy.

STUDY OBJECTIVE: To evaluate the feasibility and efficiency of operative hysteroscopy in physiologic saline solution. DESIGN: Prospective observational study (Canadian Task Force classification II-2). SETTING: Tertiary university hospital. PATIENTS: One hundred sixteen women (56% menopausal) with intrauterine pathology with or without symptoms, in whom malignancy was excluded by endometrial sampling. INTERVENTION: Operative hysteroscopy for resection of uterine septa, lysis of adhesions, and resection of myomas or polyps using a bipolar electrical energy system (VersaPoint) developed for this purpose. MEASUREMENTS AND MAIN RESULTS: Polyps were significantly more common in menopausal than in premenopausal women. Symptoms (mainly bleeding) occurred in 66.9% of premenopausal and 74.5% of menopausal patients. Endometrial polyps and submucous myomata were associated with symptoms in 68% and 70%, respectively. Operating time was less than 25 minutes. Two specimens revealed malignancy. One uncomplicated uterine perforation occurred. CONCLUSION: This new technique has the potential to replace monopolar-based intrauterine interventions and may become the treatment of choice for benign intrauterine pathology.

Laparoscopic surgery for extrauterine pregnancy in hemodynamically unstable patients.

STUDY OBJECTIVE: To assess the feasibility and safety of laparoscopic surgery in treatment of ectopic pregnancy in hemodynamically unstable women. DESIGN: Three-year observational study (Canadian Task Force classification II-2). SETTING: Tertiary university hospital. PATIENTS: One hundred one women with ectopic pregnancy who underwent laparoscopic surgery, 18 with substantial intraabdominal bleeding and with clinical signs and symptoms of hemodynamic instability. INTERVENTION: Laparoscopic surgery. MEASUREMENTS AND MAIN RESULTS: Compared with stable patients, hemodynamically unstable women had significantly more free blood in the abdomen (1244 +/- 590 vs 173 +/- 301 ml, p <0.0001), had significantly lower hemoglobin levels (7.8 +/- 1.4 vs 11.9 +/-1.4 g%, p <0.0001), and required significantly more frequent blood transfusions (83% vs 3.6%, p <0.0001). Similarly, their hemodynamic values such as pulse rate and blood pressures were worse. Among these women, 15 (83%) had a tubal pregnancy, 2 had an interstitial pregnancy, and 1 had a tubal abortion. Those with tubal pregnancy who were hemodynamically unstable underwent salpingectomy. Only one required conversion to laparotomy. No major intraoperative or postoperative complications occurred, and all women made a full and uneventful recovery. CONCLUSION: Improved anesthesia and cardiovascular monitoring, together with advanced laparoscopic surgical skills and experience, justifies operative laparoscopy for surgical treatment of ectopic pregnancy even in women with hemodynamic instability.

Adnexal torsion with a paraovarian cyst in a teenage girl.

Adnexal torsion with a paraovarian cyst in adolescent or premenarchal girls is extremely rare and very difficult to diagnose before surgery. We identified three published cases of the disorder in adolescent or premenarchal girls. Our patient, a 12.5-year-old girl, is the fourth. The cyst was excised and the adnexa untwisted at laparoscopy. High awareness and timely laparoscopy contributed to conservation of the adnexa in our young patient.

[Intraventricular hemorrhage in full-term neonates].

Intraventricular hemorrhage in full-term neonates is rare; it may develop without any clinical signs. Its cause is not fully understood although some risk factors have been identified. A higher index of suspicion would ensure earlier diagnosis and treatment, which might reduce the rate of severe complications. We describe 2 cases in full-term neonates.

Continous flow vaginoscopy in children.

The inspection of the vagina may be necessary in childhood whenever abnormal bleeding or persistent vulvovaginitis occurs. The intact and narrow laryngeal ring is a significant obstacle to the physician. Continuous-flow vaginoscopy using the hysteroscope and normal saline for irrigation and distention is very quick, easy and efficacious. Procedures, such as hemostasis, biopsy or foreign body removal can be performed during its application.

Morbidity and mortality among very-low-birth-weight neonates with intrauterine growth restriction. The Vermont Oxford Network.

OBJECTIVE: We sought to determine the associations between intrauterine growth restriction and neonatal morbidity and mortality, as well as the impact of prenatal glucocorticoid administration on the frequency of specific complications of prematurity among neonates with intrauterine growth restriction. STUDY DESIGN: We examined the association between intrauterine growth restriction and adverse neonatal outcomes in a population of 19,759 singleton very-low-birth-weight neonates without major birth defects. We included neonates from 25 to 30 weeks' gestation entered in the Vermont Oxford Network database between 1991 and 1996 by 196 institutions. Intrauterine growth restriction was defined as the 10th percentile for birth weight according to the 1993 US national statistics. Odds ratios were estimated according to stepwise logistic regression for each neonatal outcome. Potential explanatory variables included gestational age, intrauterine growth restriction, race, prenatal care, prenatal glucocorticoid administration, route of delivery, fetal sex, and birth within versus postnatal transfer to a network institution. RESULTS: There was a statistically significant association of intrauterine growth restriction with neonatal death (odds ratio, 2.77; 95% confidence interval, 2.31-3. 33), necrotizing enterocolitis (odds ratio, 1.27; 95% confidence interval, 1.05-1.53), and respiratory distress syndrome (odds ratio, 1.19; 95% confidence interval, 1.03-1.36). There was a trend (P <. 10) toward association of intrauterine growth restriction with increased risks of intraventricular hemorrhage (odds ratio, 1.13; 95% confidence interval, 0.99-1.29) and severe intraventricular hemorrhage (grades III and IV; odds ratio, 1.25; 95% confidence interval, 0.98-1.59). Maternal prenatal glucocorticoid administration was associated with significantly lower risks of respiratory distress syndrome (odds ratio, 0.51; 95% confidence interval, 0.44-0.58), intraventricular hemorrhage (odds ratio, 0.67; 95% confidence interval, 0.61-0.73), severe intraventricular hemorrhage (odds ratio, 0.50; 95% confidence interval, 0.43-0.57), and death (odds ratio, 0.54; 95% confidence interval, 0.48-0.62). The benefits of prenatal glucocorticoid therapy for growth-restricted newborns were similar to those among normally grown infants. CONCLUSIONS: Intrauterine growth restriction within the range of 501 to 1500 g birth weight is associated with increased risks of neonatal death, necrotizing enterocolitis, and respiratory distress syndrome. Prenatal corticosteroid use was associated with decreased risks of all outcomes studied except necrotizing enterocolitis. We found no evidence that this benefit was dependent on fetal size.
