Hysteroscopic guided, laparoscopic excision of caesarean scar defect: video presentation of a combined technique.

ABSTRACT: With increasing rates of delivery by caesarean section has come an increase in rates of associated complications, including caesarean scar defect. Whilst the management of this issue remains controversial, evidence is building for surgical management of such a defect for resolution of menstrual symptoms, pain and subfertility. We present a case report and surgical video of a hysteroscopic guided, laparoscopic excision of a caesarean scar defect. Following the successful management of this case and a literature review of the technique, we conclude this to be a safe, feasible and effective procedure with a low rate of complications.

Project description:BackgroundCaesarean scar pregnancy (CSP) is a type of ectopic pregnancy where the fertilised egg is implanted in the muscle or fibrous tissue of the scar after a previous caesarean section. Management options for women who opted for termination of CSP include sharp curettage, dilation and evacuation (D&E), excision of trophoblastic tissues, local or systemic administration of methotrexate, bilateral hypogastric artery ligation, and selective uterine artery embolisation with curettage and/or methotrexate administration. Recently hysteroscopic resection has also been proposed as an alternative option.ObjectiveTo compare the surgical outcome of hysteroscopic resection with dilation and evacuation (D&E) for the treatment of caesarean scar pregnancy (CSP).MethodsParallel-group, non-blinded, randomised clinical trial conducted at a single centre in Italy. Eligible women are those with singleton gestations at less than 9 weeks of gestation, and with thickness of myometrial layer ≥1 mm at the level of the ectopic. Inclusion criteria are women with CSP with positive embryonic/fetal heart activity who opted for termination of pregnancy. Patients will be randomised 1:1 to receive either hysteroscopic resection (i.e. intervention group) or D&E (i.e. control group). In both groups, 50 mg/m2 (based on DuBois formula for body surface area) of methotrexate (MTX) will be injected intramuscularly at the time of randomisation (day 1) and another dose at day 3. A third dose of MTX is planned in case of persistence of fetal heart activity on day 5. Participants will receive either D&E or hysteroscopic resection from 3 to 7 days after the last dose of MTX. A sample size of 54 women is planned.Main outcome measuresThe primary outcome is the success rate of the treatment protocol, defined as no requirement for further treatment until complete resolution of the CSP as demonstrated by negative beta hCG levels and absence of residual gestational material on ultrasound examination..Study hypothesisHysteroscopic surgery is superior to D&E for the treatment of CSP.What is new?The results of the trial will provide information on the best treatment for CSP.

Project description:IntroductionA uterine niche is a defect at the site of the uterine caesarean scar that is associated with gynaecological symptoms and infertility. Promising results are reported in cohort studies after a laparoscopic niche resection concerning reduction of gynaecological symptoms in relation to baseline and concerning pregnancy outcomes. However, randomised controlled trials to study the effect of a laparoscopic niche resection on reproductive outcomes in infertile women are lacking. This study will answer the question if laparoscopic niche resection in comparison to expectant management improves reproductive outcomes in infertile women with a large uterine niche.Methods and analysisThe LAPRES study is a randomised, non-blinded, controlled trial, including 200 infertile women with a total follow-up of 2 years. Women with the presence of a large niche in the uterine caesarean scar and unexplained infertility of at least 1 year or failed IVF will be randomly allocated to a laparoscopic niche resection within 6 weeks or to expectant management for at least 9 months. A large niche is defined as a niche with a depth of >50% of the myometrial thickness and a residual myometrium of ≤3 mm on transvaginal ultrasound. Those receiving expectant management will be allowed to receive fertility therapies, including assisted reproductive techniques, if indicated. The primary outcome is time to ongoing pregnancy, defined as a viable intrauterine pregnancy at 12 weeks' gestation. Secondary outcome measures are time to conception leading to a live birth, other pregnancy outcomes, received fertility therapies after randomisation, menstruation characteristics, patient satisfaction, quality of life, additional interventions, and surgical and ultrasound outcomes (intervention group). Questionnaires will be filled out at baseline, 6, 12 and 24 months after randomisation. Ultrasound evaluation will be performed at baseline and at 3 months after surgery.Ethics and disseminationThe study protocol was approved by the medical ethics committee of the Amsterdam University Medical Centre. (Ref. No. 2017.030). Participants will sign a written informed consent before participation. The results of this study will be submitted to a peer-reviewed journal for publication.
