NCT03131596

Brief Summary

In this prospective, randomized, controlled study, the investigators wish to determine the efficacy of intrauterine balloon (IUB) dilatation in the prevention of adhesion reformation when compared with the conventional management.

Outcome Measures

Primary Outcomes (3)

  • Number of Participants With Adhesion Reformation (American Fertility Society Score of Greater Than 0) 8 Weeks Later After the Index Surgery

    The American Fertility Society (AFS) score ranges from 0-12, while represented the severity of the adhesions. Mild 1-4, Moderate 5-8, Severe 9-12. The lower the AFS score is, the better the prognosis the patient is. When the surgery was finished the AFS score should be 0. The reformation of intrauterine adhesions was evaluated by third-look hysteroscopy, if the score was greater than 0, a adhesion reformation was considered.

    at 8 weeks post-operation

  • The American Fertility Society Score 8 Weeks After Operation

    The American Fertility Society(AFS) score of each group was evaluated again at third-look hysteroscopy in order to reflect the efficacy of the treatment. The original AFS score was recorded in baseline characteristics part. The AFS score ranges from 0-12, while represented the severity of the adhesions. Mild 1-4, Moderate 5-8, Severe 9-12. The lower the AFS score is, the better the prognosis the patient is. When the surgery was finished the AFS score score should be 0.

    at 8 weeks post-operation

  • Pictorial Blood Loss Assessment Chart Score 8 Weeks After Operation

    The Pictorial Blood Loss Assessment Chart (PBAC) score was used to represent the menstrual flow volume of the patient. The PBAC score was evaluated again at 8 weeks after surgery. A higher PBAC score after hysteroscopic adhesiolysis means a better outcome.The PBAC score of a normal women usually range from 30-100 points. The minium value of PBAC score is 0, which means the patient is amenorrhea. The maximum value of PBAC score is 1000. We measured the score before and 8 weeks after the operation in order to assess if there was any improvement (higher than before) in menstrual flow.

    at 8 weeks post-operation

Secondary Outcomes (1)

  • Pregnancy Outcome Within 12 Months Follow-up After Third Look Hysteroscopy

    within 12 months after third look hysteroscopy(8 weeks post-operation)

Study Arms (2)

IUB dilatation therapy

EXPERIMENTAL

The patient will have Foley-catheter intrauterine balloon dilatation 2 weeks and 6 weeks after hysteroscopic adhesiolysis. A second-look hysteroscopy will be carried out in the early proliferative phase 4 weeks after the surgery and third-look hysteroscopy will be carried out 8 weeks after the surgery.

Procedure: IUB dilatation therapy

control group

NO INTERVENTION

Patient will not undergo any balloon therapy. A second-look hysteroscopy will be carried out in the early proliferative phase 4 weeks after the surgery and third-look hysteroscopy will be carried out 8 weeks after the surgery.

Interventions

A Foley catheter (size 14fr) will be prepared by cutting the excess catheter tip protruding beyond the balloon prior to insertion into the uterine cavity. Once the catheter has reached the fundus, 3-4.5mls of saline will be slowly introduced into the balloon under ultrasound guidance, in order to directly visualize the distention of the cavity and division of any intrauterine adhesions, if present.
