Multicentre randomised controlled trial comparing the safety in the first 12 h, efficacy and maternal satisfaction of a double balloon catheter and prostaglandin pessary for induction of labour.

OBJECTIVE: To evaluate the safety in the first 12 h, efficacy and maternal satisfaction of a double balloon catheter (DBC) with vaginal prostaglandin (PGE) for induction of labour (IOL). METHODS: We conducted a multicentre randomised controlled study of 420 patients from 1st January 2016 to 31st December 2017 to evaluate the use of DBC in IOL in an Asian population looking at the adverse effects in the first 12 h after insertion. Women were assigned randomly to cervical ripening with either a DBC or a prostaglandin pessary. The adverse events in the 12 h after DBC or first prostaglandin inserted, the efficacy of a DBC to a prostaglandin in labour induction and maternal satisfaction were evaluated. RESULTS: There were significantly less women with uterine hyperstimulation in the DBC (2 vs 24, p ≤ 0.0001) compared to the prostaglandin group. There were no women with uterine hyperstimulation and non-reassuring foetal status in the DBC while there were 5 women with uterine hyperstimulation and foetal distress in the prostaglandin group. Use of entonox was significantly less in the DBC group (p = 0.009). There were no significant differences in both groups in caesarean section, vaginal deliveries and time to delivery, although significant less time was needed to achieve cervical os dilation more than 4 cm in the DBC group (p ≤ 0.0001). Neonatal birth outcomes were similar. Women's pain scores were similar for both methods. 80.1% of women allocated the DBC and 76.8% of women allocated the PGE were keen to recommend their method of induction. CONCLUSION: Double balloon catheter remains a good alternative method for inducing women in view of a good safety profile with low risk of hyperstimulation and high maternal satisfaction.

Patient satisfaction with the cervical ripening balloon as a method for induction of labour: a randomised controlled trial.

INTRODUCTION: Evidence has shown that balloon catheters are as effective as prostaglandins (PGE) in achieving vaginal delivery within 24 hours of the start of induction of labour (IOL), with lower rates of uterine hyperstimulation, and similar Caesarean section and infection rates. International guidelines recommend mechanical methods as a method of IOL. We designed a prospective randomised controlled study to evaluate patient acceptance of the cervical ripening balloon (CRB) for IOL. METHODS: Suitable women with a singleton term pregnancy without major fetal anomaly suitable for vaginal delivery were recruited and randomised to receive the CRB or PGE on the day of IOL. Characteristics of the women, labour and birth outcomes were obtained from case notes. Pain and satisfaction scores were obtained by interviewing the women at IOL and after delivery. The main outcome measures were participant characteristics, labour and birth outcomes, pain score, satisfaction scores, and whether the participant would recommend the mode of IOL. RESULTS: There was no difference in the pain score between the two groups at the start of IOL, but thereafter, pain scores were lower in the CRB group compared to the PGE group (4.5 ± 2.3 vs. 5.6 ± 2.4, p = 0.044). Women were equally satisfied with both methods and equally likely to recommend their method for IOL. CONCLUSION: Patient experience of IOL with CRB or PGE was equally satisfactory, although pain during induction was lower in the CRB group. We found that both methods of IOL are acceptable to women and should be made available to provide more options.

Retained calcified fibroid fragments after uterine artery embolization for fibroids.

OBJECTIVE: To document a case of retained calcified fibroid fragments after uterine artery embolization (UAE) for fibroids. DESIGN: Case report. SETTING: Teaching district general hospital. PATIENT(S): A woman with past history of UAE for fibroids. INTERVENTION(S): Bilateral UAE. MAIN OUTCOME MEASURE(S): Retained calcified fibroid fragments. RESULT(S): Retained calcified fibroid fragments can occur after UAE. CONCLUSION(S): Retained calcified fibroid fragments can occur after UAE and may be associated with infertility and menstrual disorders. Measures to detect this complication in women with these problems who have undergone UAE are appropriate.

A kink is not always a perforation: assessing Essure hysteroscopic sterilization placement.

OBJECTIVE: To highlight the fallacy of using a kink in the microinsert outline on plain abdominal x-ray as a marker for tubal perforation. DESIGN: Case report. SETTING: West London District general hospital. PATIENT(S): 36-year-old Asian woman requesting permanent sterilization. INTERVENTION(S): Essure hysteroscopic sterilization followed by abdominal x-ray, pelvic ultrasound, and laparoscopy. MAIN OUTCOME MEASURE(S): Absence of tubal perforation. RESULT(S): A patient presented with clinically suspected fallopian tube perforation 3 days after Essure hysteroscopic sterilization. Her transvaginal scan was inconclusive, but the plain x-ray demonstrated a kink within the left microinsert outline. Diagnostic laparoscopy did not identify a perforation, and bilateral tubal placement was confirmed after salpingectomy. CONCLUSION(S): This case highlights the difficulty of relying on imaging in the acute setting to establish a diagnosis of tubal perforation after hysteroscopic sterilization.
