Isthmocoele
Correction

Isthmocoele correction is a surgical procedure designed to repair a defect or scar tissue formation at the site of a previous caesarean section incision in the uterus.

This condition, known as Isthmocoele or caesarean scar defect, can lead to various symptoms and complications, including abnormal bleeding, pelvic pain, and infertility.

Isthmocoele correction involves surgically removing the scar tissue and repairing the defect, typically using minimally invasive techniques such as laparoscopy or hysteroscopy.

An Isthmocoele is a niche or defect that forms at the site of a caesarean section scar on the uterus. This condition can lead to a variety of symptoms and is often identified through imaging studies or during evaluations for infertility.

  • Causes: The exact cause of isthmocele is not fully understood, but it is associated with improper healing of the caesarean section incision. Factors that may contribute to its development include surgical technique, the number of caesarean sections, and the healing response of the uterine tissue.
  • Symptoms: Symptoms of isthmocele can vary but commonly include:
    • Abnormal uterine bleeding (especially post-menstrual spotting)
    • Pelvic pain or discomfort
    • Infertility or difficulty conceiving
    • Chronic vaginal discharge
  • Risk Factors: The risk factors for developing an isthmocele include:
    • Multiple caesarean sections
    • Short interval between pregnancies
    • Surgical technique used during caesarean delivery
    • Presence of uterine infections or other complications during or after caesarean section
  • Treatment Options: The primary treatment for isthmocele is surgical correction. Treatment options include:
    • Laparoscopic Isthmocele Correction: This minimally invasive procedure involves using a laparoscope to remove the scar tissue and repair the defect in the uterine wall. This approach offers a faster recovery time and less postoperative pain compared to open surgery.
    • Hysteroscopic Isthmocele Correction: In this procedure, a hysteroscope is inserted through the vagina and cervix to access the uterus. The scar tissue is then excised, and the defect is repaired from within the uterine cavity.
    • Medication: Hormonal treatments may be prescribed to manage symptoms such as abnormal bleeding, though they do not correct the underlying defect.
  • Monitoring: In cases where symptoms are mild, regular monitoring and follow-up with a healthcare provider may be recommended.

Isthmocoele primarily results from the healing process following a caesarean section. The exact mechanisms are not entirely clear, but several factors can contribute to its development:

  • Surgical Technique: The method used to close the uterine incision during a caesarean section can impact the formation of scar tissue.
  • Number of Caesarean Sections: Women who have had multiple caesarean sections are at a higher risk of developing an isthmocele.
  • Healing Response: Individual variations in the healing process can affect the formation of scar tissue and the integrity of the uterine wall.
  • Infections and Complications: Infections or other complications during or after a caesarean section can interfere with proper healing and increase the risk of scar tissue formation.

The symptoms of Isthmocoele can vary depending on the size and location of the defect, as well as the individual’s overall health. Common symptoms include:

  • Abnormal Uterine Bleeding: Post-menstrual spotting or bleeding between periods is a common symptom.
  • Pelvic Pain or Discomfort: Some women experience chronic pelvic pain or discomfort, particularly during menstruation.
  • Infertility: Difficulty conceiving can be a significant concern for women with an isthmocele, as the defect can interfere with sperm transport and implantation.
  • Chronic Vaginal Discharge: Persistent vaginal discharge may occur due to fluid accumulation in the scar tissue.

Several factors can increase the risk of developing an Isthmocoele, including:

  • Multiple Caesarean Sections: Each subsequent caesarean section increases the likelihood of scar tissue formation and defects.
  • Short Interval Between Pregnancies: Insufficient time for the uterus to heal fully between pregnancies can contribute to the development of an isthmocele.
  • Surgical Technique: Certain techniques used during caesarean section, such as single-layer closure of the uterine incision, may increase the risk.
  • Infections: Uterine infections or other complications during or after caesarean section can interfere with proper healing and increase the risk of scar tissue formation.

The primary treatment for Isthmocoele is surgical correction, aimed at removing the scar tissue and repairing the defect in the uterine wall. Treatment options include:

Laparoscopic Isthmocoele Correction

  • Procedure: A minimally invasive technique where small incisions are made in the abdomen. A laparoscope and specialised instruments are inserted to excise the scar tissue and repair the defect.
  • Benefits: Faster recovery, reduced pain, and minimal scarring compared to open surgery.

Hysteroscopic Isthmocoele Correction

  • Procedure: A hysteroscope is inserted through the vagina and cervix to access the uterine cavity. The scar tissue is then removed, and the defect is repaired from within.
  • Benefits: No abdominal incisions, quick recovery, and less postoperative discomfort.

Medication

  • Purpose: Hormonal treatments, such as oral contraceptives or progestin, may be used to manage symptoms like abnormal bleeding.
  • Limitations: Medications do not correct the underlying defect but can provide symptom relief.

Monitoring

  • Approach: For women with mild symptoms, regular monitoring and follow-up with a healthcare provider may be sufficient.
  • Purpose: To keep track of symptoms and intervene if they worsen or affect fertility.
