8942 Development of a Novel Physical Exam for Patients Undergoing Laparoscopic Excision of Endometriosis

Study Objective To create and validate a standardized physical exam for patients undergoing laparoscopic excision of endometriosis surgery. Design Prospective observational feasibility study. Setting Large academic hospital. Patients or Participants Patients (n = 17) undergoing operative laparoscopy for management of endometriosis were consented and enrolled before surgery and followed up to 6 weeks postoperatively. This is an ongoing study with plan to enroll 30 participants. Interventions N/A. Measurements and Main Results We developed a physical exam that included numerical pain ratings from regions typically affected by endometriosis. The complete exam was conducted at the preoperative visit and a modified version was performed at 2-week and 6-week postoperative visits for patient comfort. Composite pain scores were calculated from the modified physical exam to quantify physical symptom severity. These scores were compared to a validated patient-reported outcome measure for pain, Brief Pain Inventory (BPI). The composite physical exam pain scores improved progressively following surgery, decreasing from a median of 22.5 (IQR 14-34.29) preoperatively to 11.5 (IQR 5.26-16) at 6-weeks postoperative (p=0.072 using Wilcoxon signed-rank test). This was consistent with a decrease in average pain reported using BPI (p= 0.063). Spearman correlation coefficients showed a moderate correlation between preoperative physical exam scores and BPI (rho = 0.5419). Conclusion Currently, there is no consensus physical exam to describe symptom severity for patients with chronic pelvic pain. We report a novel standard physical exam to describe endometriosis symptom severity. Even though our results were not statistically significant, we observed a reduction in physical exam pain scores reported before and after surgery, which correlated with pain scores collected using a validated pain questionnaire. This proposed exam could be used to objectively follow up success of endometriosis excision. Our study is currently underpowered and anticipate achieving statistical significance after completing recruitment.
