Brief Summary:

The treatment of uterine niche ranges from clinical management with expectant or pharmacological treatment, surgical treatment. Approaches for repair include Laparotomy, laparoscopy , hysteroscopy , vaginal. The decision to treat takes into consideration the size of the defect, presence of symptoms, secondary infertility and plans of pregnancy.

All of the approaches have its merits and debates. There is ongoing debate regarding the best surgical approach to managing this condition. To date no randomized controlled trials have been published to settle this debate.

Our study aim is to to evaluate which surgical approach is a preferable option, this study will be conducted to compare the Laparoscopic and transvaginal approaches in several regards, including, operation time, blood loss, perioperative complications, hospital stay length, postoperative increase in residual myometrial thickness during follow-up , clinical efficacy(percentage of patients who subject improvement of symptoms)

Arm Intervention/treatment
Active Comparator: Laparoscopic approach group(A)
Uterine niche will be repaired through Laparoscopic approach.

Primary Outcome Measures :
  1. Clinical efficacy [ Time Frame: 3 month postoperative ]
    Number of patients who subject clinical improvement of pre-operative symptoms

  2. Post-operative increase in residual myometrial thickness [ Time Frame: 3 month postoperative ]
    difference between pre-operative & post-operative residual myometrial thickness

Secondary Outcome Measures :
  1. Duration of operation [ Time Frame: baseline( During operation) ]
    duration from anesthesia till end of operation

  2. Blood loss [ Time Frame: baseline( During operation) ]
    estimated blood loss during operation(towels , suction container)

  3. Intra-operative complication [ Time Frame: baseline( During operation) ]
    complication during the operation

Inclusion Criteria:

- Patients who have uterine niche (defined as myometrial discontinuity or a hypoechoic triangle in the myometrium of the anterior uterine wall at the site of hysterotomy presented in transvaginal ultrasound or sonohysterography examination in non-pregnant women) ,with one or more previous caesarean section Who are:

  1. Symptomatic i.e patients having one or more of the following symptoms:

    1. Postmenstrual spotting (defined as more than 2 days of brownish discharge at the end of menstruation with a total length of menstruation (including spotting) of more than 7 days, or intermenstrual bleeding which starts within 5 days after the end of menstruation. [15]),

    4. Chronic pelvic pain can be defined as intermittent or constant pain in the lower abdomen or pelvis of a woman of at least 6 months in duration, not occurring exclusively with menstruation or intercourse and not associated with pregnancy.
    5. secondary infertility (defined by the World Health Organization as, ―when a woman is unable to bear a child, either due to the inability to become pregnant or the inability to carry a pregnancy to a live birth following either a previous pregnancy or previous ability to carry a pregnancy to a live birth.)
