Management of an Intrauterine Device Migration Resulting in a Pregnancy - Clinical Case.

Intrauterine devices (IUD) are one of the most commonly used methods of contraception worldwide. The long term effect makes it desirable by most patients. The insertion of an IUD is not difficult as a technique but it involves multiple complications such as uterine perforation and migration into the abdominal cavity, urinary bladder perforation, fistula formation, bowel perforation and intra-abdominal adhesions. We present the case of a 31-year-old female patient (para=4) with a medical history of an IUD insertion during her postpartum period in February 2018. In April 2019, during her normal follow up consultation, the speculum examination did not detect any IUD strings and the abdominopelvic ultrasound showed no signs of the device inside the uterine cavity. A subsequent X-ray identified the device in a horizontal position in the pelvic region. The patient was scheduled for surgical intervention, but in the meantime she became pregnant. Decision to continue with the pregnancy was taken and surgery was delayed until the postpartum period. In August 2020, a laparoscopic surgical procedure was performed; during the intervention, the IUD was identified in the anterior rectal wall with only the strings exiting the wall. Therefore, a visceral surgeon advice was required. The device was removed by continuing the laparoscopic intervention. The patient was given antibiotic treatment and had a favorable evolution. Although IUD is thought to be an easy and accessible method of contraception, complications such as uterine perforation must always be taken in consideration and well explained to all patients.

Medical treatment of ectopic pregnancies: a randomized clinical trial comparing methotrexate-mifepristone and methotrexate-placebo.

BACKGROUND: Medical treatment of ectopic pregnancies is common. To increase the efficacy of methotrexate, the association of mifepristone has been proposed. METHODS: We performed a large prospective multicentre double-blind sequential randomized trial in order to compare the efficacy of methotrexate and mifepristone (600 mg given orally) versus methotrexate and placebo. RESULTS: A total of 212 ectopic pregnancies was randomized. There was no significant difference in the initial characteristics between the two groups. There was no significant difference in the success rate of medical treatment between the methotrexate-mifepristone (n = 113) and the methotrexate-placebo group (n = 99): 79.6% (90/113) versus 74.2% (72/97) respectively, RR (95% CI): 1.07 (0.92-1.25), P = 0.41, non-significant. However, there was a quantitative interaction between progesterone level and effect of treatment: when progesterone level was >/=10 ng/l, the efficacy of the combination of mifepristone and methotrexate was significantly higher than the combination of methotrexate and placebo, with an 83.3% success rate (15/18) versus 38.5% (5/13) respectively. CONCLUSIONS: Our study failed to demonstrate any benefit of the addition of mifepristone to methotrexate. By contrast, the quantitative interaction between treatment effect and baseline serum progesterone suggested that this combination could be limited to ectopic pregnancies associated with high serum progesterone concentrations.

Cervical length and funneling at 22 and 27 weeks to predict spontaneous birth before 32 weeks in twin pregnancies: a French prospective multicenter study.

OBJECTIVE: Our aim was to determine the accuracy of cervical length and funneling of the internal os in the prediction of the spontaneous very preterm birth of twin pregnancies. STUDY DESIGN: In a prospective study at 13 centers, routine transvaginal ultrasound scanning was used to examine 251 women with twin pregnancies at 22 weeks of gestation and 215 women at 27 weeks of gestation; cervical length, spontaneous cervical funneling, and funneling after transfundal pressure were evaluated. Receiver operating characteristic curve analysis was used to determine the best cervical length for the prediction of spontaneous preterm birth before 32 and 35 weeks of gestation. We calculated the sensitivity, specificity, and predictive values for cervical length and for funneling. RESULTS: The median gestational age at delivery was 36 weeks in both populations. Of the population that was included at 22 weeks of gestation, 5.2% (13 women) gave birth spontaneously before 32 weeks of gestation, and 13.2% (33 women) gave birth spontaneously before 35 weeks of gestation; the median cervical length was 40 mm. The receiver operating characteristic curve showed no clear best cutoff point for cervical length. For spontaneous delivery before 32 and 35 weeks of gestation, the sensitivity of cervical length < or =30 mm was 46% and 27%, respectively; the specificity was 89% and 90%, respectively. The sensitivity of funneling was 54% and 33%, and its specificity 89% and 91%, respectively. After multivariate analysis, only funneling remained significant for delivery before both 32 and 35 weeks of gestation. Of the population that was included at 27 weeks, 3.3% (7 women) gave birth spontaneously before 32 weeks of gestation, and 12.4% (26 women) gave birth spontaneously before 35 weeks of gestation; the median cervical length was 35 mm. The receiver operating characteristic curve showed 25 mm to be the best cutoff point for cervical length. For spontaneous delivery before 32 and 35 weeks of gestation, the sensitivity of cervical length < or =25 mm was 100% and 54%, respectively, and the specificity was 84% and 87%, respectively. The sensitivity of funneling was 86% and 54%, and the specificity 78% and 82%, respectively. After multivariate analysis, both indicators remained significant for delivery before 35 weeks of gestation. Funneling after transfundal pressure at 22 or 27 weeks did not predict very preterm delivery. CONCLUSION: Cervical length and funneling both predict the very preterm birth of twins. Although cervical length is the predictor of choice at 27 weeks of gestation, at 22 weeks of gestation the diagnostic values of both parameters are close.
