Incidence of opioid-managed pelvic pain after hysteroscopic sterilization versus laparoscopic sterilization, US 2005-2012.

Objective: Compare incidence of opioid-managed pelvic pain within 12 months after hysteroscopic and laparoscopic sterilization.

Methods: Using administrative claims, we identified women aged 18-49 years without recent history of childbirth who underwent hysteroscopic or laparoscopic sterilization between 2005 and 2012. We defined the outcome as ≥2 diagnoses for pelvic pain and ≥2 prescription fills for opioids. We calculated adjusted hazard ratios (HR) using Cox models and propensity score methods (matching and inverse-probability-of-treatment-weighting [IPTW]).

Results: We identified 71,875 eligible women (hysteroscopic n = 26,927 [37.5%], laparoscopic n = 44,948 [62.5%]). Of those, 236 (0.88%) hysteroscopic patients and 420 (0.93%) laparoscopic patients experienced the outcome (crude HR = 0.97, 95%CI: [0.83, 1.14]). Adjusted analyses also yielded near-null results (matched HR = 1.08, 95%CI [0.90, 1.31]; IPTW HR = 0.97, 95%CI [0.80, 1.18]). While most sensitivity analyses generated results close to the null, hazard ratios estimated using propensity score matching ranged from 0.65 to 1.53.

Conclusions: Among women without recent history of childbirth, we did not find compelling evidence of a clinically meaningful increase in the incidence of pelvic pain requiring opioids during the year after hysteroscopic sterilization. However, effects observed in sensitivity analyses may merit further investigation.
