Endometriosis Severity Score Calculator

The Endometriosis Severity Score Calculator is a specialized clinical tool used to assess the extent and severity of endometriosis, a chronic gynecological condition where tissue similar to the lining of the uterus (endometrium) grows outside the uterine cavity. Endometriosis can cause severe pain, infertility, and other debilitating symptoms. The severity of the condition is generally categorized into stages based on the extent, depth, and location of endometrial implants, adhesions, and ovarian involvement. The Endometriosis Severity Score Calculator helps clinicians evaluate the stage of the disease, guide treatment decisions, and monitor disease progression or response to treatment.

What is Endometriosis?

Endometriosis is a chronic inflammatory condition affecting women of reproductive age. It is characterized by the growth of endometrial-like tissue outside the uterus, commonly on the ovaries, fallopian tubes, peritoneum, and other pelvic organs. These tissues respond to hormonal changes in the menstrual cycle, causing inflammation, pain, cyst formation, scar tissue, and adhesions. Endometriosis can lead to symptoms such as pelvic pain, dysmenorrhea (painful periods), dyspareunia (pain during intercourse), bowel and bladder dysfunction, and infertility.

How the Endometriosis Severity Score Calculator Works

The Endometriosis Severity Score Calculator is based on the Revised American Society for Reproductive Medicine (rASRM) classification, which grades the disease into four stages: minimal (Stage I), mild (Stage II), moderate (Stage III), and severe (Stage IV). This scoring system takes into account the size, location, and depth of endometrial implants, the presence and extent of adhesions, and the involvement of ovaries and fallopian tubes. The calculator provides a numerical score that corresponds to a specific stage, helping clinicians understand the disease burden.

To use the Endometriosis Severity Score Calculator, the clinician or patient inputs specific details observed during a pelvic exam, ultrasound, or laparoscopy, such as:

• Size and location of endometrial implants: Superficial or deep implants on organs like the ovaries, peritoneum, or bowel are recorded and scored.
• Extent and depth of implants: The calculator considers whether the implants are superficial or deeply infiltrative, which indicates a more severe form of endometriosis.
• Presence of adhesions: Adhesions are bands of scar tissue that can cause organs to stick together. The score accounts for the presence, density, and location of adhesions (e.g., on the ovaries or between the uterus and bowel).
• Ovarian involvement: The presence of ovarian cysts (endometriomas), their size, and their impact on ovarian function are included in the scoring.
• Fallopian tube involvement: The extent of fallopian tube adhesions or blockage due to endometriosis is evaluated.

The calculator assigns points based on the severity and extent of these factors. The total score determines the stage of endometriosis:

• Stage I (Minimal): Few superficial implants, no significant adhesions.
• Stage II (Mild): More implants, both superficial and deep, with minor adhesions.
• Stage III (Moderate): Many deep implants, with possible presence of small endometriomas and filmy adhesions.
• Stage IV (Severe): Large endometriomas, dense adhesions, extensive implants, and significant pelvic involvement.
