Pregnancy following cesarean scar defect (niche) repair: a cohort study.

PURPOSE: The aim of the study is to learn the obstetrical outcome of women after laparoscopic niche repair. METHODS: A retrospective cohort study including all women after laparoscopic niche repair done by a single high-skilled surgeon, from July 2014 to March 2019. Data were collected from women's medical records and a telephone interview was performed to assess further symptoms and attempts to conceive, including pregnancy outcomes. RESULTS: During the study period, 48 women underwent laparoscopic niche repair, of them complete follow-up was achieved for 37 (78.7%) women. The median residual myometrial thickness measured by ultrasound before the repair was 2.0 mm (IQR 1.4-2.5). Attempts to conceive were reported by 81% (n = 30) of the women, while 18 (60%) achieved pregnancy in median time of 6 month (IQR 5-12) post-niche repair. 14 (78%) of the women conceived spontaneously. No placental abnormalities were reported in any of the women. All gave birth by cesarean delivery at a median of 38.4 gestation week (IQR 37.0-39.5). No dehiscence or rupture was reported. CONCLUSIONS: Pregnancy following niche repair can be achieved with low pregnancy complication rate and good pregnancy outcomes. Further studies need to be done to strengthen our findings.

Long-term outcome of MR-guided focused ultrasound treatment and laparoscopic myomectomy for symptomatic uterine fibroid tumors.

BACKGROUND: Fibroid tumors are the most common benign tumors in women of reproductive age. Treatment is usually indicated for those who are symptomatic, with different techniques being used. OBJECTIVE: The purpose of this study was to compare the long-term outcome of laparoscopic myomectomy with magnetic resonance-guided focused ultrasound for symptomatic uterine fibroid tumors. STUDY DESIGN: A cohort study was conducted on all patients with symptomatic uterine fibroid tumors who were admitted to a single tertiary care center and treated operatively with laparoscopic myomectomy or treated conservatively with magnetic resonance-guided focused ultrasound from January 2012 until January 2017. Assessment for further interventions and sustained fibroid-associated symptoms was performed, with the use of the Uterine Fibroid Symptom and Quality of Life symptom severity score. RESULTS: One hundred fifty-four women met the inclusion criteria. Complete follow-up evaluation was achieved for 64 women who underwent laparoscopic myomectomy and for 68 women who were treated by magnetic resonance-guided focused ultrasound. Follow-up time was similar for the 2 groups (median, 31 months [interquartile range, 17-51 months] vs 36 months [interquartile range, 24-41]; P=.95). The rate of additional interventions was 5 (7.8%) and 9 (13.2%), respectively (P=0.312). Similarly, the Uterine Fibroid Symptom and Quality of Life symptom severity score questionnaire score at follow-up interviews revealed comparable median scores of 17 (interquartile range, 12-21) vs 17 (interquartile range, 13-22) for laparoscopic myomectomy and magnetic resonance-guided focused ultrasound, respectively (P=.439). Analysis of each of the symptoms separately (bleeding, changes in menstruation, abdominal pain, bladder activity, nocturia, fatigue) did not change these findings, nor did a multivariate analysis. CONCLUSION: Satisfaction with long-term outcome and rate of reinterventions after magnetic resonance-guided focused ultrasound treatment or laparoscopic myomectomy for uterine fibroid tumors was comparable. Further larger randomized trials are needed to confirm these findings.

In-office Hysteroscopic Extraction of Intrauterine Devices in Pregnant Patients Who Underwent Prior Ultrasound-guided Extraction Failure.

STUDY OBJECTIVE: To determine an effective method of intrauterine device (IUD) retrieval from pregnant women who had previous unsuccessful ultrasound-guided IUD extraction failure. DESIGN: A retrospective cohort study (Canadian task force classification II-1). SETTING: A gynecology department of an outpatient clinic. PATIENTS: Pregnant patients in their first trimester with IUD in situ who underwent prior unsuccessful ultrasound-guided IUD extraction. INTERVENTIONS: Hysteroscopic IUD extraction guided by transabdominal ultrasound. MEASUREMENTS AND MAIN RESULTS: Between 2011 and 2014, 7 of 8 pregnant patients who had undergone previous failed attempts at IUD retrieval via ultrasound guidance underwent successful removal via ultrasound-guided hysteroscopy performed without anesthesia. The sole patient with extraction failure was in her 12th week of pregnancy, and the procedure was concluded to avoid risk to the fetus. Minimal vaginal bleeding was experienced by 2 patients after the procedure. Seven of 8 patients delivered at term without any obstetric complications. One patient had a miscarriage in her 8th week of pregnancy, 2 weeks after successful IUD removal. CONCLUSION: A novel, easy outpatient hysteroscopic technique without anesthesia is presented in case of failure of previous ultrasound-guided IUD removal in early pregnancy. Results are encouraging in this difficult context.

Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) for prophylactic bilateral salpingo-oophorectomy.

BACKGROUND: Prophylactic bilateral salpingo-oophorectomy (BSO) is an important option for reducing the risk of developing ovarian and fallopian tube cancers in women with a hereditary ovarian cancer syndrome. Conventional laparoscopy is generally preferable since it is associated with less morbidity compared to laparotomy. Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) is an emerging surgical approach that offers several advantages over conventional laparoscopy including reduced postoperative pain, low rate of surgical site infections, fast patient recuperation and better cosmetic outcome [1-6]. The objective of this video is to demonstrate a surgical technique for vNOTES BSO. METHODS: This is a Stepwise demonstration of the vNOTES for prophylactic BSO with narrated video footage. The diameter of Alexis is 7 cm and we used the GelPOINT V-path transvaginal access platform (Applied Medical, Rancho Santa Margarita, CA). RESULTS: A 52-year-old carrier of BRCA1 mutation. The patient was selected to be operated on via a vaginal port. The video presents some tips and tricks to aid the surgeon to perform this surgery in a safe and timely manner, using the vaginal GEL POINT system and vNOTES technique. CONCLUSIONS: vNOTES for prophylactic BSO via a vaginal port is a feasible technique with promising cosmetic results. This technique allows surgeon to expose the ureter well and lower the risk of ureteric injury. Additionally, this approach avoids abdominal wall vessels injury associated with the trocar insertion. Currently, as a result of certain technical limitations, such as when performing BSO without a hysterectomy, there has been a tendency to employ the vaginal access less frequently. In this video presentation, we demonstrate the feasibility of laparoscopic BSO via vNOTES whilst leaving the uterus intact.

Feasibility and efficacy of repeated hysteroscopic cesarean niche resection.

OBJECTIVE: Cesarean-induced niche can cause symptoms such as abnormal postmenstrual bleeding, pain and associated infertility. Hysteroscopic niche resection is usually a successful treatment, but can result in a failure to improve symptoms or symptoms can recur. In the present study we aim to evaluate the feasibility, effectiveness, and safety of a second hysteroscopic niche resection for patients in whom an initial hysteroscopic resection failed to improve symptoms. STUDY DESIGN: This retrospective cohort study (Canadian Task Force classification II-2) hospital tell hashomer (tertiary center) included all patients who underwent a second hysteroscopic niche resection between 2011 and 2015. MEASUREMENTS: Fertility,obstetric outcomes, clinical outcome and complications were compared between the first surgery and the second RESULTS: Eight patients underwent a second hysteroscopy after failure of the first hysteroscopy to resolve symptoms or after recurrence of symptoms. Abnormal uterine bleeding (AUB) was the most common symptom, occurring in all patients. The average number of days of bleeding per cycle were significantly reduced following the second surgery [14.50 (range 8-21days) vs 11.75 (range 8-20days), respectivelyp=0.009]. The second surgery improved symptoms in 6 out of the 8 patients with AUB and 1 of 2 patients with pain. There were no significant differences in fertility and obstetric outcomes between the first and the second surgery and no complications were reported during any of the surgeries. CONCLUSION: Reintervention with a second hysteroscopic niche resection is both feasible and effective treatment option following a failed first attempt or recurrence of symptoms. The second surgery improved symptoms, especially AUB, with no consequent detrimental effect on obstetric outcomes on our series.

Sonographic Signs of Adenomyosis Are Prevalent in Women Undergoing Surgery for Endometriosis and May Suggest a Higher Risk of Infertility.

OBJECTIVES: To determine the prevalence of ultrasound features suggestive of adenomyosis in women undergoing surgery for endometriosis compared with a control group of healthy women without endometriosis. METHODS: Retrospective case-control study comparing women with intractable pain or infertility, who underwent transvaginal ultrasound and subsequent laparoscopic surgery, with a control group of healthy women without a previous history of endometriosis. A diagnosis of adenomyosis on TVUS was made based on asymmetrical myometrial thickening, linear striations, myometrial cysts, hyperechoic islands, irregular endometrial-myometrial junction, parallel shadowing, and localized adenomyomas and analyzed for one sign and for three or more signs. RESULTS: The study and control groups included 94 and 60 women, respectively. In the study group, women were younger and had more dysmenorrhea and infertility symptoms. The presence of any sonographic feature of adenomyosis, as well as three or more signs, was found to be more prevalent in the study group, which persisted after controlling for age, for all features but linear striations. Women in the study group who had five or more sonographic features of adenomyosis had more than a threefold risk of suffering from infertility (OR = 3.19, p = 0.015, 95% CI; 1.25-8.17). There was no association with disease severity at surgery. CONCLUSIONS: Sonographic features of adenomyosis are more prevalent in women undergoing surgery for endometriosis compared to healthy controls. Women with more than five features had an increased risk of infertility.

Applying a statistical method in transvaginal ultrasound training: lessons from the learning curve cumulative summation test (LC-CUSUM) for endometriosis mapping.

BACKGROUND: Methods available for assessing the learning curve, such as a predefined number of procedures or direct mentoring are lacking. Our aim was to describe the use of a statistical method to identify the minimal training length of an experienced sonographer, newly trained in deep infiltrating endometriosis (DIE) mapping by evaluating the learning curve of transvaginal ultrasound (TVUS) in the preoperative assessment of endometriosis. METHODS: A retrospective study in a tertiary referral center for endometriosis. Reports and stored data from TVUS scans performed by one operator with training in general gynecological ultrasound, but not in endometriosis mapping, were analyzed retrospectively for patients who subsequently underwent laparoscopy, which served as a reference standard. The performance of TVUS was assessed for the following sites: endometriomas, bladder, vagina, pouch of Douglas, bowel and uterosacral ligaments, and correlated with laparoscopic findings. Sensitivity, specificity, PPV, NPV, and accuracy were calculated, and the operator's diagnostic performance was assessed using the learning curve cumulative summation test (LC-CUSUM). RESULTS: Data from 94 women were available for analysis. The learning curve using the LC-CUSUM graph showed that the sonographer reached the predefined level of proficiency in detecting endometriosis lesions after 20, 26, 32, 31, 38, and 44 examinations for endometriomas, bladder nodules, vaginal nodules, pouch of Douglas obliteration, bowel nodules, and uterosacral ligament nodules, respectively. CONCLUSIONS: LC-CUSUM allows monitoring of individual performance during the learning process of new methodologies. This study shows that a sonographer trained in general gynecologic ultrasonography, who devotes time to learn TVUS for DIE mapping, can achieve proficiency for diagnosing the major types of endometriotic lesions after examining less than 50 patients who subsequently undergo surgery in a training setting.

Hysteroscopically guided transvaginal ultrasound tubal catheterization-a novel office procedure.

OBJECTIVE: Investigate a novel office hysteroscopic tubal catheterization therapeutic method for proximal tubal occlusion. STUDY DESIGN: Prospective cohort study in a tertiary referral center. We evaluated the procedure on a group of 27 patients that were referred to our unit for proximal tubal occlusion demonstrated by hysterosalpingography, 9 (33.3%) of them with primary infertility and 18 of them (66.6%) with secondary infertility. The intervention included the usage of the modified Novy cornual cannulation set which was inserted through a 5F working cannel during an office operative hysteroscopy, followed by fallopian tube irrigation with saline-air mixture under ultrasonographic imaging. RESULTS: Our series revealed no complication during or after the procedure; anesthesia was not required. One patient lost from follow-up. Of the remaining 26, 10 patients (38.4%) conceived either spontaneously or with treatment by clomiphene or gonadotropine associated with intrauterine insemination. The median time to conception was 5 months (range 4-17). CONCLUSION: We therefore concluded that office hysteroscopic tubal catheterization is a simple (without anesthesia required) option for the treatment of patients suffering from proximal tubal occlusion. Fertility outcomes in our series are comparable to other treatments options for tubal catheterization. Therefore, tubal catheterization should not delay the assisted reproducted techniques if indicated but we propose to include it in a global integrated approach.

Emergency laparoscopy for suspected ovarian torsion: are we too hasty to operate?

OBJECTIVE: To reevaluate the rate of correct diagnosis of ovarian torsion (OT) in our department. DESIGN: Retrospective computerized chart review. SETTING: Tertiary referral center. PATIENT(S): Seventy-eight women who underwent laparoscopy for suspected OT. INTERVENTION(S): Laparoscopy. MAIN OUTCOME MEASURE(S): Rate of true diagnosis of torsion, correlation with Doppler studies. RESULT(S): The preoperative diagnosis of OT was confirmed in only 36 (46.1%) of the patients. Immediate operation (<10 hours) after admission (n = 48) was associated with a statistically significantly higher likelihood of operatively confirming OT (56.2% vs. 28.6%). We found that the lack of ovarian blood flow on Doppler sonography was a good predictor of OT; women with pathologic flow were statistically significantly more likely to have OT (77% vs. 29%). The sensitivity and specificity of abnormal ovarian flow for OT were 43.8% and 91.7%, respectively, with a positive and negative predictive value of 78% and 71%, respectively. CONCLUSION(S): Despite 20 years of research, the accuracy of the preoperative diagnosis of OT remains low. The urge to operate can be attributed to the importance of preserving ovarian function in young women as well as to the availability and the low associated complication rate of laparoscopy.

High failure rates of medical termination of pregnancy after introduction to a large teaching hospital.

The success rates of medical termination of pregnancy in two time periods (2000-2001 and 2002-2003) were compared to assess the effectiveness of medical abortion introduction to a large academic tertiary medical center. The success rates were markedly reduced over time (87.0% vs. 79.3%) probably owing to the difficulty in defining clear sonographic criteria for treatment failure and the complexity of a follow-up program implemented at a large teaching hospital by a broad staff with widely varying experience and knowledge of the new procedure.

Laparoscopic treatment of cornual pregnancy: a series of 20 consecutive cases.

OBJECTIVE: To determine the outcome of laparoscopic management of cornual pregnancy. DESIGN: Retrospective cohort study (Canadian Task Force classification II-3). SETTING: A tertiary referral hospital in Israel. PATIENT(S): Twenty-seven consecutive women with cornual pregnancy who were diagnosed and treated at our institute. INTERVENTION(S): Laparoscopy was undertaken in 20 (74%) of the patients. Resection of the cornua and/or a Vicryl loop placement was performed. In 6 cases, laparoscopy was converted to laparotomy. In addition, laparotomy was performed in 2 other cases. Five cases were managed conservatively: 3 with systemic methotrexate (MTX) and leucovorin, 1 with transvaginal sonography-guided KCl injection to the amniotic sac, and 1 with hysteroscopic-guided MTX injection to the amniotic sac. Further treatment after surgery was required in 4 cases: transvaginal sonography-guided KCl injection, MTX or KCl + MTX (1 case each) injection to the amniotic sac, and systemic MTX injection. MAIN OUTCOME MEASURE(S): Successful laparoscopy, determined as not needing follow-up treatment. RESULT(S): The mean gestational age was 56 days. The average and median serum hCG levels were 31,199 and 6,653 IU/mL, respectively. Six of the women (22%) were admitted in hypovolemic shock. Nine patients (33.3%) were asymptomatic upon admission, 14 (52%) had abdominal pain, and 8 (29.6%) were evaluated for vaginal bleeding. One woman developed hypovolemic shock after admission. Only 15 (55.6%) of the 27 pregnancies were diagnosed as a cornual pregnancy by transvaginal sonography before the therapeutic procedure. Blood transfusion was given in seven cases (26%) during surgery. The mean number of days of hospitalization was 5.7 days for patients who underwent surgery and was 7.1 days for all patients. A comparison was made between the first 11 and the last 11 cases treated surgically. Although the two groups were similar in all parameters, conversion from laparoscopy to laparotomy was higher in the first group, although not at a statistically significant level. CONCLUSION(S): Improved laparoscopic technique, accumulated experience, and possibly earlier diagnosis have led to fewer operative failures or need to convert to laparotomy during treatment of cornual pregnancy. Conservative treatment, when possible, should be considered. If surgery is indicated, and as more laparoscopic skill is gained, laparoscopy should be considered the preferred method of treating cornual pregnancy. In experienced hands, laparoscopy is a safe and effective treatment for cornual pregnancy.
