Background/purpose: The purpose of the present study was to evaluate the role of laparoscopy in diagnosis the cases of chronic pelvic pain. Methods: This prospective study was conducted among 100 women who had been suffering from chronic pelvic pain for ≥6 months at Department of Obstetrics & gynaecology, Muzaffarnagar Medical College, Muzaffarnagar from December 2017 to December 2018. After proper selection of cases, a detailed history followed by general, systemic and pelvic examination, diagnostic laparoscopy of the patient was done and noted as per the following protocol. Diagnostic laparoscopy was performed under general anaesthesia using a 5–mm Karl Stortz 30° angle double port laparoscope. The data was collected and subjected to statistical analysis using SPSS version 22.00 Results: Majority (70%) of patients with CPP were in the age group between 26 – 30 years and 31 – 35 years. Two most common causes of CPP detected clinically were endometriosis and chronic PID which together constituted about 56% of the cases with CPP in our study group. Laparoscopy findings revealed that 90% of patients with CPP have one or more positive findings, the commonest being endometriosis in various pelvic sites with or without endometrioma (34%) Conclusion: It can be concluded that ideally hysteroscopy should be performed simultaneously to identify intrauterine pathologies, which can be associated with CPP and which are missed by laparoscopy. Hence combined laparohysteroscopy is the ideal method for diagnosis of CPP.
