Utility of Office Hysteroscopy in Diagnosing Retained Products of Conception Following Early Pregnancy Loss After In Vitro Fertilization.

OBJECTIVE: To evaluate the utility of office hysteroscopy in diagnosing and treating retained products of conception in patients with infertility who experience early pregnancy loss (EPL) after in vitro fertilization (IVF). METHODS: We evaluated a retrospective cohort of 597 pregnancies that ended in EPL in patients aged 18-45 years who conceived through fresh or frozen embryo transfer at an academic fertility practice between January 2016 and December 2021. All patients underwent office hysteroscopy after expectant, medical, or surgical management of the EPL. The primary outcome was presence of retained products of conception at the time of office hysteroscopy. Secondary outcomes included incidence of vaginal bleeding, presence of intrauterine adhesions, treatment for retained products of conception, and duration of time from EPL diagnosis to resolution. Log-binomial regression and Poisson regression were performed, adjusting for potential confounders including oocyte age, patient age, body mass index, prior EPL count, number of prior dilation and curettage procedures, leiomyomas, uterine anomalies, and vaginal bleeding. RESULTS: Of the 597 EPLs included, 129 patients (21.6%) had retained products of conception diagnosed at the time of office hysteroscopy. The majority of individuals with EPL were managed surgically (n=427, 71.5%), in lieu of expectant management (n=140, 23.5%) or medical management (n=30, 5.0%). The presence of retained products of conception was significantly associated with vaginal bleeding (relative risk [RR] 1.72, 95% CI 1.34-2.21). Of the 41 patients with normal pelvic ultrasonogram results before office hysteroscopy, 10 (24.4%) had retained products of conception detected at the time of office hysteroscopy. When stratified by EPL management method, retained products of conception were significantly more likely to be present in individuals with EPL who were managed medically (adjusted RR 2.66, 95% CI 1.90-3.73) when compared with those managed surgically. Intrauterine adhesions were significantly less likely to be detected in individuals with EPL who underwent expectant management when compared with those managed surgically (RR 0.14, 95% CI 0.04-0.44). Of the 127 individuals with EPL who were diagnosed with retained products of conception at the time of office hysteroscopy, 30 (23.6%) had retained products of conception dislodged during the office hysteroscopy, 34 (26.8%) chose expectant or medical management, and 63 (49.6%) chose surgical management. The mean number of days from EPL diagnosis to resolution of pregnancy was significantly higher in patients who elected for expectant management (31 days; RR 1.18, 95% CI 1.02-1.37) or medical management (41 days; RR 1.54, 95% CI 1.25-1.90) when compared with surgical management (27 days). CONCLUSION: In patients with EPL after IVF, office hysteroscopy detected retained products of conception in 24.4% of those with normal pelvic ultrasonogram results. Due to the efficacy of office hysteroscopy in diagnosing and treating retained products of conception, these data support considering office hysteroscopy as an adjunct to ultrasonography in patients with infertility who experience EPL after IVF.

Premature progesterone elevation during the early and mid-follicular phases in fresh in vitro fertilization (IVF) cycles is associated with lower live birth, clinical pregnancy, and implantation rates.

PURPOSE: Evaluate follicular phase progesterone elevation (≥ 1.5 ng/mL) prior to trigger during IVF stimulation and its effects on live birth rate (LBR), clinical pregnancy rate (CPR), and implantation rate (IR) in fresh IVF cycles. METHODS: This was a retrospective cohort study within an academic clinic. A total of 6961 fresh IVF and IVF/ICSI cycles from October 1, 2015 to June 30, 2021 were included and grouped by progesterone (PR) prior to trigger: PR < 1.5 ng/mL (low PR group) and PR ≥ 1.5 ng/mL (high PR group). Main outcome measures included LBR, CPR, and IR. RESULTS: Among all cycle starts, 1568 (22.5%) were in the high PR group and 5393 (77.5%) were in the low PR group. Of the cycles which proceeded to an embryo transfer, 416 (11.1%) were in the high PR group and 3341 (88.9%) were in the low PR group. The high PR group had significantly lower IR (RR 0.75; 95% CI 0.64-0.88), CPR (aRR 0.74; 95% CI 0.64-0.87), and LBR (aRR 0.71; 95% CI 0.59-0.85) compared to the low PR group. When stratified by progesterone on the day of trigger (TPR), there was a clinically notable decrease in IR (16.8% vs 23.3%), CPR (28.1% vs 36.0%), and LBR (22.8% vs 28.9%) in the high PR group compared to the low PR group even when TPR < 1.5 ng/mL. CONCLUSIONS: In fresh IVF cycles in which TPR < 1.5 ng/mL, progesterone elevation ≥ 1.5 ng/mL at any point in time prior to trigger negatively impacts IR, CPR, and LBR. This data supports testing of serum progesterone in the follicular phase prior to trigger, as these patients may benefit from a freeze-all approach.

Sonographic Predictors of Ovarian Torsion in Premenarchal Girls.

STUDY OBJECTIVE: To identify preoperative transabdominal sonographic predictors of surgically confirmed ovarian torsion (OT) in premenarchal girls METHODS: We conducted a retrospective case-control study of 32 premenarchal girls aged 0-12 undergoing surgery for OT (cases) or a non-torsed ovarian mass (controls) from 2006 to 2017 at a single academic center. Cases had ICD-9/10 codes for torsion of the ovary, adnexa, ovarian pedicle, or fallopian tube and surgically confirmed OT; controls had codes for ovarian mass or cyst and surgically confirmed absence of OT. Preoperative transabdominal ultrasounds were analyzed by 3 radiologists blinded to final diagnosis. We used χ2, Fisher[s exact, and Student's t tests for statistical comparisons. RESULTS: From 2016 to 2017, 32 patients presented with acute abdominal pain or symptoms concerning for ovarian mass requiring ultrasound imaging and subsequent diagnostic laparoscopy; 24 (75.0%) had confirmed OT by laparoscopy, and 8 (25.0%) did not. The mean age in both groups was similar (7.3 ± 2.9 years). Preoperative sonographic variables significantly associated with OT included presence of a simple cyst (20.8% vs 12.5%), ovarian heterogeneity (100% vs 12.5%), presence of peripheralized follicles (70.8% vs 0%), and asymmetry of color Doppler (75.0% vs 37.5%; all P < .05). Presence of free fluid, arterial color Doppler, and a whirlpool sign were not predictive of OT. CONCLUSION: In premenarchal patients, although certain variables on transabdominal sonography predicted surgically confirmed OT, only the presence of peripheralized follicles was unique to girls with OT. The decision to proceed with diagnostic laparoscopy for suspected OT can be aided by these specific sonographic findings but should ultimately be based on high clinical suspicion.
