ABSTRACT
OBJECTIVE: To investigate the clinical efficacy and safety of Helica Thermal Coagulator (TC) in the treatment of pelvic pain associated with minimal (stage I) and mild (stage II) endometriosis. DESIGN: A clinical observational study. SETTING: A referral center for laparoscopic treatment of endometriosis. PATIENT(S): Eighty-one women with pelvic pain symptoms associated with minimal and mild endometriosis diagnosed at laparoscopy. INTERVENTION(S): Helica TC to treat endometriotic lesions. The revised American Fertility Society (rAFS) classification was used to stage endometriosis. Pain symptoms and patient satisfaction were assessed subjectively at 3 and 6 months follow-up. MAIN OUTCOME MEASURE(S): Improvement or relief of pelvic pain symptoms, and intra- or postoperative complications. RESULT(S): A total of 79 women completed the study to 6 months follow-up. At 3 months, 59 (74.7%) women reported resolution and satisfactory improvement of symptoms, whereas 20 (25.3%) women continued to experience painful symptoms. At 6 months, 69 (87.4%) women reported resolution and satisfactory improvement of symptoms, whereas 9 (11.4%) women reported no changes and 1 (1.2%) woman experienced worsening symptoms. No significant differences were found between minimal and mild disease. No side effects or surgical complications occurred. CONCLUSION(S): Meaningful improvements and relief in clinical symptoms can be obtained with conservative laparoscopic surgery. Helica TC is a simple, effective, and safe device for the treatment of pelvic pain in women with stages I and II endometriosis. This approach requires further evaluation as part of randomized controlled trials.
