Methods This was a retrospective cohort study of asymptomatic high‐risk singleton pregnancies with a short cervix and history of sPTB, treated using Arabin pessary or vaginal progesterone for primary PTB prevention, conducted at four European hospitals. A log‐rank test on Kaplan–Meier curves was used to assess the difference in performance of pessary and progesterone, according to history of PTL‐IM or PPROM. Linear regression analysis was used to evaluate significant predictors of gestational age at delivery. Results Between 2008 and 2015, 170 women were treated with a pessary and 88 with vaginal progesterone. In women treated with a pessary, rate of sPTB < 34 weeks was 16% in those with a history of PTL‐IM and 55% in those with a history of PPROM. In women treated with progesterone, rate of sPTB < 34 weeks was 13% in those with a history of PTL‐IM and 21% in those with a history of PPROM. Treatment with a pessary resulted in earlier delivery in women with previous PPROM than in any other subgroup (P < 0.0001). Linear regression analysis showed a clear effect of PPROM history (P < 0.0001), combination of PPROM history and treatment (P = 0.0003) and cervical length (P = 0.0004) on gestational age at birth. Conclusions Cervical pessary may be a less efficacious treatment option for women with previous PPROM; however, these results require prospective validation before change in practice is recommended. Phenotype of previous preterm birth may be an important risk predictor and treatment effect modifier; this information should be reported in future clinical trials

Cervical pessary for preventing preterm birth in twin pregnancies with short cervical length: a systematic review and meta-analysis

OBJECTIVE: To evaluate the effectiveness of cervical pessary for preventing spontaneous preterm birth (SPTB) in twin pregnancies with an asymptomatic transvaginal ultrasound cervical length (TVU CL) in the second trimester. METHODS: We performed a meta-analysis including all randomized clinical trials (RCTs) comparing the use of cervical pessary (i.e. intervention group) with expectant management (i.e. control group). The primary outcome was incidence of SPTB <34 weeks. RESULTS: Three trials, including 481 twin pregnancies with short cervix, were analyzed. Two RCTs defined short cervix as TVU CL ≤25 mm and one as TVU CL ≤38 mm. Pessary was not associated with prevention of SPTB, and the mean gestational age at delivery and the mean latency were similar in the pessary group compared to the control group. Moreover, no benefits were noticed in neonatal outcomes.\ud CONCLUSIONS: Use of the Arabin pessary in twin pregnancies with short TVU CL at 16-24 weeks does not prevent SPTB or improve perinatal outcome

Practice patterns and 90-day treatment-related morbidity in early-stage cervical cancer

Successful laparoscopic surgical removal of a caesarean scar pregnancy (CSP) using temporary uterine artery ligation

Study Objective: To demonstrate a laparoscopic technique to remove a scar pregnancy. Design: Stepwise demonstration of the surgical technique. Setting: Santa Croce and Carle Hospital, Cuneo. Intervention: Patient B.B. is a woman referred to our center for a suspected cesarean scar pregnancy (CSP) at 9 weeks gestation. CSP occurs approximately in 6% of all ectopic pregnancies. The estimated incidence is reported to be 1:1800 to 1:2500 in cesarean deliveries. Depending on its location, CSP can be categorized as either type 1, if the growth is in the uterine cavity, or type 2, if it expands toward the bladder and the abdominal cavity. If inadequately managed, it can lead to severe complications; most of them are hemorrhagic and can threaten the woman's life. There are several therapeutic approaches: local excision seems to be the most effective choice in type 2 CSP. In expert hands, the laparoscopic approach is perhaps the best surgical choice as tissue dissection, electrosurgical hemostasis, and vascular control can be effectively managed with minimal invasive access. Because severe intraoperative bleeding can occur, retroperitoneal vascular control is mandatory in this surgery. In type 1 CSP curettage, aspiration or hysteroscopic approach can be considered if the CSP is of small dimensions. A hysteroscopic approach can also be helpful in type 2 CSP during the laparoscopic removal, as intrauterine guidance. A potassium chloride local injection can be considered in a preoperative stage in the presence of a fetal heart rate. The systemic administration of methotrexate is usually ineffective as single agent, but it can be useful if administered as adjuvant therapy. Uterine artery embolization can be useful in an emergency setting to manage severe bleeding, but it can lead to complications in subsequent pregnancies and, more rarely, to premature ovarian failure. Considering poor bleeding at presentation, feasible dimensions, and the woman's desire for future pregnancy, ultrasound-guided aspiration and curettage was attempted. Because endouterine removal was incomplete, methotrexate injection was proposed as adjuvant therapy, but the administration was postponed as the patient tested positive for coronavirus disease 2019. A month later, beta-human chorionic gonadotropin level dropped from over 16 000 to 271 mU/mL, so an ultrasound and biochemical follow-up was performed. A month later, despite a low beta-human chorionic gonadotropin value, an increase in dimensions was observed at ultrasound, so surgical laparoscopic removal was offered. In this video article, laparoscopic removal of scar pregnancy is discussed in the following surgical steps: (1) Temporary closure of uterine arteries at the origin, using removable clips. (2) Retroperitoneal dissection to safely manage the scar pregnancy. (3) Dissection of the myometrial-pregnancy interface. (4) Double layer suture on the anterior uterine wall. Conclusion: Laparoscopic surgical management is a very effective surgical approach to remove CSP. Knowledge of retroperitoneal dissection and vascular control is necessary to carry out this surgical intervention safely and effectively.

Neoadjuvant Chemotherapy Prior Fertility-Sparing Surgery in Women with FIGO 2018 Stage IB2 Cervical Cancer: A Systematic Review

Nowadays, the optimal management of patients with cervical cancers measuring 2–4 cm desiring to maintain fertility is still uncertain. In this systematic review, we assessed the reliability of neoadjuvant chemotherapy (NACT) prior to fertility-sparing (FS) surgery in International Federation of Gynecology and Obstetrics (FIGO) 2018 stage IB2 cervical cancer, in terms of pathologic response, oncological and obstetric outcomes. The review of the literature was performed following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Data, using MEDLINE and PubMed, were searched for from 1 January 2005 up to 1 December 2020. We identified 20 articles and 114 women with IB2 disease, possible candidates for NACT prior to FS surgery. However, uterine conservation was achieved only in 76.7% of them. Patients reached optimal pathological response to NACT in 60.9% of cases and a TIP (cisplatin, ifosfamide and paclitaxel) regime was related to the best response. Suboptimal response to NACT appeared to be an independent negative prognostic factor. Up to 9.2% of patients recurred with a median 7.4-months DFS, and 4.6% of patients died of disease. Fifty percent of women tried to conceive after treatment and NACT prior to conization appeared to be the most promising alternative to upfront radical trachelectomy in terms of obstetric outcomes. In conclusion, NACT prior to FS surgery is an option, but the literature about this issue is still weak and FS should be carefully discussed with patients
