Objective: To investigate the efficacy of laparoscopic uterine nerve ethanol neurolysis (LUNEN) for pain man­agement in patients with chronic pelvic pain (CPP).
Methods: LUNEN, as a chemical neurolysis procedure, was performed on 22 subjects, and these were com­pared with 20 controls that had a diagnostic laparoscopy alone. Pre-treatment and postoperative 6th month Visual Analogue Scale (VAS) scores were estimated and a sub­jective pain evaluation questioning patients’ satisfaction about pain relief in the 6th month after surgery was also performed.
Results: A total of 31 (73.8%) out of 42 CPP patients had a laparoscopic pelvic pathology. Preoperative VAS scores were similar in the groups; however, the mean postop­erative VAS score was significantly lower in the LUNEN group than in the control group (3.18 ± 2.88 vs. 5.35 ± 3.09; p=0.02). In the LUNEN group, the number of pa­tients who stated that their pain was relieved partially or completely was also significantly higher than in the con­trol group (82% vs. 40%, p=0.019).
Conclusion: LUNEN is a feasible, safe and effective sur­gical alternative to traditional surgical methods in patients suffering from CPP.
