Cervical stenosis is a challenging condition that often recurs despite intervention. Multiple therapeutic options have been described, but a clearly effective and reliable treatment method has yet to be identified. Patients with recurrent stenosis are at risk of developing severe complications such as chronic pelvic pain and infertility. We describe a case of congenital cervical stenosis with secondary haematometra in which repeated cervical dilatation, hysteroscopic canalisation and administration of medications to retard endometrial development were unsuccessful in relieving the obstruction and preventing re-accumulation of menstrual blood. Total hysterectomy was eventually mandated by spontaneous rupture of the haematometra.

INTRODUCTIONIn the United Kingdom, caesarean section (CS) rates have increased from 9% of deliveries in 1980 to 21% in 2001. A similar increase in CS rates has been seen in many developed countries. This is beyond the World Health Organisation's (WHO's) recommended level of 15%. This is a worrying trend as the risks of placenta previa, placenta accreta, hysterectomies, bladder and bowel injuries are increased with subsequent CS. We aim to ascertain the commonest indications for CS in a tertiary hospital and make recommendations to decrease future CS rates.

MATERIALS AND METHODSThis retrospective analysis compares the 5 most common indications for CS in 1999 and 2009. CS rates in the 2 study periods are tabulated and analysed as well.

RESULTSIn the first study period between January and December 1999, there were 2048 deliveries of which 365 were via CS. In the second study period of a decade later from January to December 2009, there were 1572 deliveries of which 531 were via CS. This gives an increase in CS rate from 17.8% in 1999 to 34% in 2009. The main indications for CS in 1999 were: cephalopelvic disproportion (18.6%), breech (14.2%), non-reassuring fetal status (11.8%), 1 previous CS (11.2%) and pregnancy-induced hypertension/pre-eclampsia/eclampsia (6.6%). The main indications for CS in 2009 were: 1 previous CS (18.1%), non-reassuring fetal status (12.2%), cephalopelvic disproportion (10.5%), 2 or more previous CS (7.9%) and breech (7.7%).

CONCLUSIONThere is a significant increase in CS rates over the last decade with an increased percentage of CS done because of a previous CS. This is associated with increased risk of complications as well. Recommendations are suggested with the view to decrease future CS rates.

We present two cases of diamniotic, dichorionic twin pregnancies in which after the loss of the first foetus in the setting of clinical chorioamnionitis, both pregnancies were successfully managed by delayed-interval delivery. A fourstage protocol including aspects of management in this specific setting is proposed. We consider the importance of a selection process when managing conservatively, measures to promote latency and decisions regarding delivery of the foetuses. Whilst we report successful case studies of conservative management with delayed-interval delivery, we support a cautious approach and understand that in the setting of clinical chorioamnionitis of the remaining foetus, delivery is necessary.

INTRODUCTIONPathologically adherent placentas occur when there is a defect of the decidua basalis, typically arising from previous caesarean section, resulting in abnormally invasive implantation of the placenta. The depth of placental invasion varies from the superficial (accreta), to transmural and possibly beyond (percreta).

CLINICAL PICTUREWe report on 2 cases, one treated "conservatively", the other with a caesarean hysterectomy, both of which led to a safe outcome for both mother and baby.

CONCLUSIONSManagement relies on accurate early diagnosis with appropriate perioperative multidisciplinary planning to anticipate and avoid massive obstetric haemorrhage at delivery.

INTRODUCTION: There has been a global decrease in operative vaginal deliveries, with a marked shift towards the vacuum extractor. However, little is known about the trends in operative vaginal delivery in Singapore. METHODS: A retrospective study was conducted on all operative vaginal deliveries performed from 2012 to 2017 at Singapore General Hospital (SGH). Maternal outcomes in terms of postpartum haemorrhage and obstetric anal sphincter injuries were compared between forceps- and vacuum-assisted deliveries. Neonatal outcomes in terms of neonatal intensive care unit (NICU) admission and clinically significant neonatal events were compared. The instrument preference of obstetricians was analysed. RESULTS: A total of 906 consecutive operative vaginal deliveries were included in the study, comprising 461 forceps- and 445 vacuum-assisted deliveries. The rate of operative vaginal delivery was maintained at approximately 10% from 2012 to 2017. Neonatal cephalohematomas were more common after vacuum-assisted deliveries. Other maternal and neonatal outcomes did not differ significantly between the two groups. Clinically significant neonatal events were mostly due to shoulder dystocia, whereas all cases of NICU admissions were not directly related to the mode of delivery. Obstetricians' choice of instrument appeared to reflect personal preference and was not affected by the year of graduation. CONCLUSION The rates of neonatal and maternal morbidity were low at SGH. Overall instrument use of forceps and vacuum was balanced, and proficiency in both was demonstrated by all operators. Operative vaginal delivery remains an essential skill in facilitating safe vaginal delivery, which should be maintained to keep Caesarean section rates in check.

INTRODUCTIONThis study aimed to determine the decision-to-delivery intervals (DDIs), total duration of surgery and factors influencing these for Caesarean sections (CSs).

METHODSA retrospective study was conducted of all CSs performed from August 2013 to June 2014 at a single tertiary general hospital. Data collected included maternal demographics, indications for CS, category of urgency, DDI, total duration of surgery, grade of first surgeon and number of previous CSs.

RESULTSIn total, 488 CSs (Category 1: n = 28; Category 2: n = 137; Category 3: n = 184; Category 4: n = 139) were studied. Overall mean duration of surgery was 41.7 minutes. Mean DDI was 23.9 minutes and 64.5 minutes for Category 1 and Category 2 CSs, respectively. For Category 1 CSs, deliveries during office hours had a significantly shorter DDI than deliveries out of office hours (p < 0.05). For Category 2 CSs, deliveries during office hours had a significantly longer DDI (p < 0.05). Total duration of surgery for senior surgeons was significantly shorter than for trainee surgeons (p < 0.05). Women with no previous CSs had a significantly shorter duration of surgery than those who had one or more (p < 0.05).

CONCLUSIONThe majority of the deliveries were within the recommended DDI corresponding to the degree of urgency of CS. The influence of time of day on DDI might be due to challenges of time taken to transfer patients to operating theatres. Total duration of surgery was influenced by surgical experience, history of previous CS and individual surgical styles and preferences.

INTRODUCTIONAlthough Caesarean sections (CSs) are among the most commonly undertaken procedures in the world, there are wide variations in the surgical techniques used. This study aimed to: (a) review the surgical techniques used for CS by obstetricians working in a tertiary hospital in Singapore; (b) compare the techniques with those recommended in evidence-based guidelines; and (c) examine the relationship between the technique used and the level of seniority of the surgeons.

METHODSData on 490 CSs performed in Singapore General Hospital (SGH) between 1 August 2013 and 30 June 2014 was collected from the Delivery Suite database and reviewed. The surgical techniques studied were closure of the pelvic and parietal peritoneum, closure of the uterine layer, use of surgical drains and use of postoperative thromboprophylaxis.

RESULTSA total of 486 CSs were analysed after four cases were excluded due to missing data. Most fetal head deliveries were manual. The majority of surgeons did not close the peritoneum; most of those who did were senior surgeons. Double-layer uterine closures were done for all cases and drain usage was rare. 2.0% of the patients received grossly inadequate thromboprophylaxis.

CONCLUSIONThe surgical techniques currently practised in SGH are closely aligned with those of the evidence-based guidelines. Peritoneal closure appears to be associated with the surgeon's early training, with a greater number of senior surgeons being less willing to abandon this step. Greater vigilance in implementing appropriate thromboprophylaxis is recommended.
