Objective: To evaluate whether persistence of pelvic pain after excision of endometriosis was associated with adenomyosis as defined by a thickened uterine junctional zone (JZ) on magnetic resonance (MR) imaging., Design: Prospective clinical trial., Setting: Government research hospital., Patient(s): Fifty-three women with chronic pelvic pain., Intervention(s): Preoperative MR imaging to measure uterine JZ thickness, surgical excision, and pathologic diagnosis of endometriosis. Those with biopsy-proven endometriosis were randomized to raloxifene or placebo. Visual analog scale (VAS) was used to rate dysmenorrhea and nonmenstrual pain severity before surgery and 3 months later., Main Outcome Measure(s): Comparison of JZ thickness and pain severity before and 3 months after surgery in women with endometriosis controlling for medical treatment., Result(s): Forty of the 53 patients had biopsy-proven endometriosis, and 6 of these 40 women with endometriosis had a thickened JZ. Overall, dysmenorrhea at 3 months was positively correlated with preoperative JZ thickness (r = 0.47, P=.01). Dysmenorrhea pain severity showed no significant decrease in those patients whose JZ measured >or=11 mm compared with those with JZ <8 mm (P<.0001; VAS decreased 4.3 +/- 0.6), or >or=8 and <11 mm (P<.02; VAS decreased 4.8 +/- 1.3). Nonmenstrual pain severity was correlated with JZ thickness (r = 0.51, P=.004) at 3 months with a significant decrease in nonmenstrual pain only in women with a JZ <8 mm (VAS decreased 4.0 +/- 0.7, P<.0001). The association between dysmenorrhea and nonmenstrual pain reduction and thinner JZ remained after controlling for medical treatment., Conclusion(s): Following surgical excision of endometriosis, chronic pelvic pain was significantly more likely to persist with JZ thickness >11mm on preoperative MR imaging. This suggests that myometrial JZ abnormalities or adenomyosis may contribute to chronic pelvic pain in women with endometriosis.

Objective: To compare an ovarian stimulation protocol using microdose follicular phase GnRH agonist (GnRH-a) and oral contraceptive (OC) pills to a luteal phase GnRH-a protocol., Design: Retrospective analysis., Setting: University affiliated IVF program., Patient(s): One hundred seventy patients who underwent IVF and ET in 1996., Intervention(s): Patients were assigned to either a midluteal start of leuprolide acetate (LA) 1 mg/d, reduced to 0.5 mg/d after addition of gonadotropins (LUT), or OC pills until cycle day 0 followed by 20 microg of LA every 12 hours on cycle day 3 with addition of gonadotropins on cycle day 5 (MICRO)., Main Outcome Measure(s): Number of FSH ampules, days of stimulation, peak E2, and number of oocytes retrieved., Result(s): There were no statistically significant differences in the main outcome measures between the two groups using an age-matched ANOVA. Clinical pregnancy rate per cycle start was not statistically different (LUT = 54%, and MICRO = 37%). The cancellation rate was significantly higher in the MICRO group (22.5% vs. 8.2%)., Conclusion(s): Given the higher cancellation rate in the microdose group, a randomized clinical trial is required to determine the possible benefit of a lower dose of GnRH-a in patients with normal ovarian function.
