Background:Endometriosis is defined as the presence of endometrial-like tissue outside the uterus, which induces a chronic, inflammatory reaction. Present study was aimed to the study effectiveness of surgery in improvement of pain associated with endometriosis by comparison of preoperative and postoperative pain score at 3months and 6 months follow up. Material and Methods: Present study was single-center, prospective, observational study, conducted in women in the reproductive age group of 18-45 yrs, with laparoscopically confirmed endometriosis. The patients were followed at 3 months and 6months and evaluation of pain relief was done using Visual analogue scale as well as Bibergolu and Behrman score. Results: Among 92 women, predominant age group in the study was 26-30 years (31.52%), mean age of the patients was 32.03 ± 5.969 years. Most of the patients 87 (94.57%) presented with dysmenorrhea, pain abdomen (61.96%), dyspareunia (59.78%), back pain (32.6%), infertility (27.17%), dyschezia (22.83%) & premenstrual gaseous distension (11.96%). On 3 months evaluation 26 (28.26%) patients improved in their bleeding pattern. On 6 months evaluation 32 (34.78%) patients improved in their bleeding pattern, this improvement in heavy menstrual bleeding was clinically significant (P value = 0.0001). At 6 months follow-up 35 (38.04%) had mild pain, 7 (7.61%) had moderate pain & no one had severe pain. The two-tailed P value was < 0.0001, difference was extremely statistically significant. As per Visual analogue scale, at 6 months follow-up 62 (67.40%) patients completely freed of pain, 32.60% (30) of patients had only mild pain. The two-tailed P value was < 0.0001, difference is considered to be extremely statistically significant. Conclusion: This study demonstrates significant decrease in pain scores (Bibergolu and Behrman scale and visual analog scale) at 3 and at 6 months follow up (P<0.05) when laparoscopic surgery was offered to patients.
