Conservative treatment of ectopic pregnancy in a sub-Saharan African setting

In the sub-Saharan African setting, laparotomy for salpingectomy is the common method of treatment for ectopic pregnancy (EP). The objective of this retrospective study was to find out how common EP is treated conservatively in the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon. Of the 281 patient files analysed, 126 patients (44.8%) were treated conservatively and successfully for EP. Of these, 86 (68.2%) had received conservative surgical treatment while 40 (31.8%) had non-surgical treatment. Salpingostomy was the conservative surgery for 79.1% of the cases. According to the publications available for the sub-Saharan setting, the rate of conservative management of EP at the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon is high. We recommend that this rate should be improved so that, eventually, the conservative treatment methods of EP become routine.

Facteurs de risque et pronostic des césariennes d’urgence à l’hôpital gynéco-obstétrique et pédiatrique de Yaoundé (Cameroun)

OBJECTIVE To identify the risk factors for emergency cesarean deliveries and assess the effects of the emergency situation on maternal and fetal prognosis. METHODS This retrospective cohort study compared emergency and elective cesarean deliveries performed at the Yaoundé Womens and Childrens Hospital in Cameroon, analyzing socioeconomic variables, the indications for surgery, and complications for mother and child. RESULTS Risk factors predisposing to emergency cesareans were: age <20 years, not having a salaried job, unmarried status, no university-level education, referral from other health facilities, primiparity, prenatal care in a health center or in a district hospital, prenatal care by a nurse, and preadmission rupture of membranes. Emergency cesareans increased the mothers risk of general anesthesia, unavailability of standard preoperative work-up during surgery, infection, and a longer hospital stay. Babies born by emergency cesarean delivery had a higher risk of admission to the neonatology unit, neonatal asphyxia, neonatal infection, preterm birth, and perinatal death. CONCLUSION In our setting, lack of reproductive experience (primiparity), low socioeconomic level, poor prenatal care, and preadmission rupture of membranes were risk factors for emergency cesarean deliveries. The emergency situation exposes mother and child to a significant risk of morbidity and mortality.

Maternal and Fetal Outcomes Following Labour at Term in Singleton Pregnancies with Meconium-Stained Amniotic Fluid: A Prospective Cohort Study

Background: Meconium stained amniotic fluid (MSAF) is frequently encountered in obstetric practice. Literature on the subject is still poorly documented in the African setting. Objective: The aim of this study was to determine the maternal and fetal outcomes in case of meconium stained amniotic fluid observed during term labour. Materials and Methods: We conducted a prospective cohort study enrolling all consenting pregnant women with term singleton fetus in cephalic presentation admitted for labour with ruptured fetal membranes in the maternity units of the Yaounde Central Hospital (YCH) and the Yaounde Gynaeco-Obstetric and Pediatric Hospital (YGOPH) of Cameroon between December 2014 and April 2015. The exposed grouped was considered as participants having MSAF, while the non-exposed group comprised those with clear amniotic fluid (CAF). The two groups were monitored during labor using the WHO partograph, and then followed up till 72 hours after delivery. Variables studied included the colour and texture of amniotic fluid as well as maternal and fetal complications. Data was analyzed using Epi-info version 3.5.4. The chi-square and Fischer’s exact tests were appropriately used to compare the two groups. A p-value less than 5% was considered statistically significant. Results: 2376 vaginal deliveries were recorded during the study period among which MSAF was observed in 265 cases, hence a prevalence rate of MSAF of 11.15%. Among these cases of MSAF, 52.1% was thick meconium and 47.9% was light meconium. Maternal morbidity was high in the group with MSAF; these included: Higher proportions of caesarean delivery (RR = 2.35 p < 10-4) and prolonged labor (RR = 3 p < 10-4). In this same group, the incidences of chorioamnionitis and puerperal sepsis were low (0.94% and 0.70% respectively), although there was a three-fold higher risk that was not statistically significant (RR = 3, P = 0.31). Fetal and neonatal outcomes were poorer in the MSAF group compared to the CAF group. The complications included fetal heart rate abnormalities, low Apgar score at the 5th minute, need for neonatal resuscitation, neonatal asphyxia and neonatal infection which were significantly higher in the MSAF group (all p < 0.05). Meconium aspiration syndrome (MAS) was found in 2.34% of MSAF cases. Perinatal mortality was 2.34% and all cases of death occurred in the thick MSAF group. Conclusion: MSAF observed during labour is associated with increased perinatal morbidity and mortality. Its detection during labor should strongly indicate very rigorous intra partum and postpartum monitoring. This will ensure optimal management and reduction in the risks of complications.

Maternal and neonatal outcomes of vaginal breech delivery for singleton term pregnancies in a carefully selected Cameroonian population: a cohort study

Background and objectives Vaginal breech delivery (VBD) is known to be associated with more perinatal and maternal complications. Very few studies on the subject have been carried out in poor-resource settings. The aim of this study was to determine maternal and neonatal outcomes in carefully selected cases of VBD for singleton term pregnancies in a tertiary centre in Cameroon. Design A retrospective cohort study. Setting A tertiary hospital in Yaounde, Cameroon. Participants Cases of VBD of newborns weighing 2500–3500 g were matched in a ratio of 1:4 to consecutive vaginal cephalic deliveries (VCDs) of newborns weighing 2500–3500 g over a 5-year period. Both groups were matched for maternal age and parity. We excluded cases of multiple gestations, footling breech, clinically inadequate maternal pelvis, preterm delivery, post-term pregnancies, fetal demise prior to the onset of labour, placenta praevia and fetal anomaly incompatible with vaginal delivery. Outcome measures Neonatal and maternal adverse outcomes of VBD observed till 6 weeks after delivery analysed using Bonferroni correction. Results Fifty-three (53) VBDs were matched against 212 VCD. Unlike women who had VCD, those who underwent VBD were more likely to have prolonged labour (OR 8.05; 95% CI 3.00 to 11.47; P<0.001), and their newborns were more likely to suffer from birth asphyxia (OR 10.24; 95% CI 4.92 to 21.31; P<0.001). Conclusion The study infers a strong association between VBD of singleton term pregnancies and maternofetal morbidity when specific protocols are applied. This, however, failed to translate into higher differences in perinatal mortality. This finding does not discount the role of VBD in low-income countries, but we emphasise the need for specific precautions like close monitoring of labour and adequate anticipation for neonatal resuscitation in order to reduce these complications.

The diagnosis of uterine cervical polyps in a low resource setting: the positive predictive value of clinical judgment--a series of 192 cases at the Yaounde Gynaeco-Obstetric and Paediatric Hospital, Cameroon.

As far as we know, the accuracy of clinical judgment in diagnosing uterine cervical polyps has not been assessed in sub-Saharan Africa. Our objective was to discover the positive predictive value (PPV) of clinical judgment in the diagnosis of cervical polyps. This is a retrospective descriptive study of 192 patients, carried out by the Departments of Pathology and Gynaecology of the Yaoundé Gynaeco-Obstetric and Paediatric Hospital, Cameroon. The diagnosis of cervical polyp was confirmed by histopathology examination in 169 patients, giving a PPV rate of 88.0%. The PPV of clinical judgment in the diagnosis of cervical polyps is acceptable in our setting but the frequency of premalignant and malignant lesions encountered is too high (10.4%), even in the presence of a confirmed cervical polyp (8.9%). Even in areas where there are limited resources, we recommend a systematic histopathology examination of any clinically suspected cervical polyp.
