The effect of CO2 laser laparoscopy for treatment of pelvic endometriosis on serum concentrations of antiendometrial antibodies

This study uses antiendometrial antibodies as an indicator for follow-up of patients with endometriosis after surgical treatment. This is a prospective study of 32 patients with endometriosis. The patients were used as their own controls. Serum samples were obtained before surgery and 1 month, 3 months, and 6-9 months following surgery. All patients were treated with CO2 laser laparoscopy. Serum concentrations of antiendometrial antibodies decreased significantly at 1 month, 3 months, and 6-9 months following treatment in each group. There was no correlation between baseline concentration of antibodies and stage of the disease. This study confirms the value of using antiendometrial antibodies as an indicator for follow-up of endometriosis patients. Surgical treatment with CO2 laser laparoscopy is effective in lowering the antigenic effect of the disease in these patients. This beneficial effect is maintained for up to 9 months after treatment.
