Brief Summary

Uterine niche is a frequent condition in patients with a history of cesarean section. Many treatment methods have been described for repair of niche with varying effectivities. In conventional Laparoscopic approach, not all bleeding points and fibrotic area are resected, while conventional hysteroscopic one result in more wide defect with high risk of recurrence and cannot be used in large niche with low RMT. In this new Double approach (hysteroscopy and laparoscopy) technique, the benefit of both laparoscopy and hysteroscopy will be attained.

Conditions

Outcome Measures

Primary Outcomes (2)

  • change of the residual myometrium thickness

    ultrasound measurement of the residual myometrium will be done

    will be measured at the 3-month and 6-month

  • reduction of postmenstrual bleeding

    participants will report their perception of the amount of bleeding using a questionnaire

    will be assessed at the 3-month and 6-month

Secondary Outcomes (1)

  • Subsequent fertility outcome

    1 year

Study Arms (2)

Laparoscopic Excision of Large Cesarean Scar Niche

ACTIVE COMPARATOR
Procedure: laparoscopic repair of cesarean scar niche

Combined Hysteroscopic and Laparoscopic Repair without Excision of Large Cesarean Scar Niche

ACTIVE COMPARATOR
Procedure: Combined hysteroscopic and laparoscopic repair of cesarean scar niche

Interventions

Intentional perforation of the niche will be done using uterine sound and excision of the fibrotic edges then suturing the uterine incision using 2-0 absorbable suture.

Also known as: laparoscopic excision of cesarean scar niche
Laparoscopic Excision of Large Cesarean Scar Niche

Hysteroscopic resection of the niche under laparoscopic guide will be done to avoid perforation of the niche. After completion of the hysteroscopic approach, laparoscopic plication of the niche without opening it will be done using multiple interrupted 2-0 absorbable suture.

Also known as: Combined hysteroscopic and laparoscopic repair without excision of large cesarean scar niche
Combined Hysteroscopic and Laparoscopic Repair without Excision of Large Cesarean Scar Niche

Eligibility Criteria

Age18 Years - 40 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • History of cesarean section Postmenstrual and or intermenstrual spotting Large Cesarean scar niche, depth more than 50% of adjacent myometrial thickness (AMT).
  • Failed medical treatment Signed informed consent.

You may not qualify if:

  • A contraindication for a hysteroscopic niche resection Women with a positive pregnancy test. A contraindication for general or local anaesthesia. Coagulation disorders that lead to higher risks on bleeding or anticoagulant use.
  • A (suspected) malignancy, endometrial polyps, atypical endometrial cells, cervical dysplasia, hydrosalpinx that may communicate with the uterus.
  • Adenomyosis or leiomyoma (the International Federation of Gynecology and Obstetrics (FIGO) leiomyomia subclassification system Type 0, 1, 2, 3) or large leiomyomas causing the uterine cavity length to be ≥ 9 cm as examined by transvaginal ultrasound or MRI.
  • Endocrine disorders that interfere with the menstrual cycle. Irregular menstrual cycle (\>35 days or intercycle variation of 2 weeks or more).
  • Patients who are not willing to conceive before and/or after the hysteroscopic surgery.
