Laparoscopic electroablation showed a more distinct tendency for reduced dysmenorrhea compared to CO2 laser ablation at six months postoperatively, though both methods did not significantly alleviate other pain complaints.

This randomized study compared laparoscopic CO2 laser ablation versus electroablation for reducing pain in 48 women (22–42 years) with varying grades of endometriosis of the lesser pelvis (including ovarian endometriosis and deep infiltrating endometriosis), assessing five pain domains using a Numeric Rating Scale at baseline and at 3 and 6 months postoperatively. Both groups reported less pain related to dysmenorrhea at 6 months, with more distinct improvement tendencies in the electroablation group, but despite initial gains at 3 months, pain intensity significantly increased by 6 months in both groups overall. A major limitation explicitly reflected in the results is attrition and reduced follow-up (e.g., not all randomized participants were assessed at 3 and 6 months, and some were excluded due to conception). This paper is centrally about endometriosis—specifically comparing laparoscopic CO2 laser ablation versus electroablation efficacy for endometriosis-related pain complaints in the lesser pelvis.

Abstract

Endometriosis is a chronic disease affecting mainly women of the reproductive age. Its most common manifestations include impaired fecundity, pelvic pain, and dyschezia. Laparoscopic removal of endometriotic foci remains to be the gold standard for the treatment of endometriosis. More effective techniques of endoscopic approach—among others, laser application—are continually being developed. The aim of the study was to evaluate the efficacy of laparoscopic treatment with the use of CO2 laser ablation vs. electroablation with regard to pain complaints in the affected patients. The study included 48 women (aged 22–42) with varying degrees of endometriosis of the lesser pelvis. The Numeric Rating Scale (NRS) was used to evaluate pain intensity before the surgery in all patients, followed by either laser ablation or electroablation of the endometriotic foci. The results of the laparoscopic treatment were monitored after 3 and 6 months postoperatively. p value of 0.05 was considered to be statistically significant. Patients from both groups reported less intensive pain before/during menstruation (dysmenorrhea) 6 months postoperatively, with more distinct tendency in the electroablation group (p = 0.004) as compared to the laser ablation group (p = 0.025). Despite the initial improvement reported at the 3-month checkup (p = 0.008), 6 months postoperatively, a statistically significant increase in pain intensity was noted in both groups (p = 0.016 and p = 0.032 for CO2 laser ablation and electroablation, respectively). Both surgical methods seem to be effective only in the treatment of endometriosis-related dysmenorrhea, whereas the intensity of other pain complaints (dyspareunia, dysuria, dyschezia, pelvic pain syndrome (PPS)) has remained on the same level.
