Objectives To evaluate pain perception and analgesic use between patients who underwent endometriosis-specific laparoscopic surgery compared to laparoscopic hysterectomy. Material and methods This retrospective cohort study included women diagnosed with endometriosis who underwent laparoscopic surgery from 1/2019 to 11/2022. The control group consisted of premenopausal women who underwent laparoscopic hysterectomy, which was considered a similarly extensive surgery. Demographics, preoperative and post-operative data were compared between groups. Post-operative pain scores on a visual analogue scale (VAS) between 0 (no pain) and 10 (worst pain) were compared between groups for each post-operative day (POD). Standard pain relief analgesia on POD 0–1 included fixed intravenous treatment with paracetamol and intramuscular diclofenac. The need for additional analgesics (morphine or dipyrone) beyond the standard pain relief protocol was compared between groups. Results Among 200 patients who underwent laparoscopic surgery, 100 (50%) were in the endometriosis group and 100 (50%) in the hysterectomy group. The endometriosis group was characterized by younger age and lower parity (both, p<0.001). There was no significant difference between the groups in mean VAS scores for each post-operative day. However, among patients who needed additional analgesics beyond the standard protocol on POD 1, a higher percentage of women in the endometriosis group used opioids rather than milder analgesics, as compared to controls (1% vs. 0.2%, respectively, p = 0.03). Conclusion Increased post-operative morphine use was observed in patients with endometriosis following laparoscopic surgery, despite no significant difference in mean VAS scores during the post-operative days. These findings suggest that personalized pain relief protocols should be adjusted for women with endometriosis.
