Laparoscopic Inguinal Exploration and Mesh Placement for Chronic Pelvic Pain

Background and Objective: Chronic pelvic pain affects 15 % of women. Our objective was to evaluate empiric laparoscopic inguinal exploration and mesh placement in this population. Methods: Retrospective cohort with follow-up question-naire of women with lateralizing chronic pelvic pain (right or left), ipsilateral inguinal tenderness on pelvic examina-tion, no clinical hernia on abdominal examination, and ipsilateral empiric laparoscopic inguinal exploration with mesh placement (2003–2009). Primary outcome was pain level at the last postoperative visit. Secondary outcomes were pain level and SF-36 scores from the follow-up questionnaire. Results: Forty-eight cases met the study criteria. Surgery was done empirically for all patients, with only 7 patients (15%) found to have an ipsilateral patent processus vagi-nalis (shallow peritoneal dimple or a deeper defect (occult hernia)). Of 43 cases informative for the primary outcome, there was pain improvement in 15 patients (35%); pain improvement then return of the pain in 18 patients (42%); and pain unchanged in 9 patients (21%) and worse in 1 patient (2%). Improvement in pain was associated with a positive Carnett’s test in the ipsilateral abdominal lower quadrant (P .024). Thirteen patients returned the ques-tionnaire (27%), and the pain was now described as im-proved in 9 patients (69%), unchanged in 4 patients (31%), and worse in none. Three SF-36 subscales showed im-provement (physical functioning, social functioning, and pain). Conclusion: In select women with chronic pelvic pain, empiric laparoscopic inguinal exploration and mesh placement results in moderate improvement in outcome. A positive Carnett’s test in the ipsilateral abdominal lower quadrant is a predictor of better outcome
