Effect of cardia banding and improved anaesthetic care on outcome of oesophageal atresia in a developing country

The burden, prevention and care of infants and children with congenital anomalies in sub-Saharan Africa: A scoping review

The aim of this scoping review was to determine the scope, objectives and methodology of contemporary published research on congenital anomalies (CAs) in sub-Saharan Africa (SSA), to inform activities of the newly established sub-Saharan African Congenital Anomaly Network (sSCAN). MEDLINE was searched for CA-related articles published between January 2016 and June 2021. Articles were classified into four main areas (public health burden, surveillance, prevention, care) and their objectives and methodologies summarized. Of the 532 articles identified, 255 were included. The articles originated from 22 of the 49 SSA countries, with four countries contributing 60% of the articles: Nigeria (22.0%), Ethiopia (14.1%), Uganda (11.7%) and South Africa (11.7%). Only 5.5% of studies involved multiple countries within the region. Most articles included CA as their primary focus (85%), investigated a single CA (88%), focused on CA burden (56.9%) and care (54.1%), with less coverage of surveillance (3.5%) and prevention (13.3%). The most common study designs were case studies/case series (26.6%), followed by cross-sectional surveys (17.6%), retrospective record reviews (17.3%), and cohort studies (17.2%). Studies were mainly derived from single hospitals (60.4%), with only 9% being population-based studies. Most data were obtained from retrospective review of clinical records (56.1%) or via caregiver interviews (34.9%). Few papers included stillbirths (7.5%), prenatally diagnosed CAs (3.5%) or terminations of pregnancy for CA (2.4%).This first-of-a-kind-scoping review on CA in SSA demonstrated an increasing level of awareness and recognition among researchers in SSA of the contribution of CAs to under-5 mortality and morbidity in the region. The review also highlighted the need to address diagnosis, prevention, surveillance and care to meet Sustainable Development Goals 3.2 and 3.8. The SSA sub-region faces unique challenges, including fragmentation of efforts that we hope to surmount through sSCAN via a multidisciplinary and multi-stakeholder approach.

Time to Death and Predictors Among Neonates with Esophageal Atresia in Ethiopia

Background

Esophageal atresia is an upper gastrointestinal tract developmental abnormality in which the upper and lower esophagus do not connect. Esophageal atresia has a higher incidence of death in sub-Saharan Africa, ranging from 30% to 80%. In Ethiopia, infants with esophageal atresia had a higher mortality rate. The assessment of time to death and predictors of esophageal atresia can help to reduce newborn mortality.

Objective

This study was aimed to investigate the time to death and predictors of neonates with esophageal atresia admitted to Tikur Anbessa Specialized Hospital, Ethiopia.

Methods

An institutional-based retrospective follow-up study was conducted among 225 neonates diagnosed with esophageal atresia. The median survival time, Kaplan–Meier failure estimation curve, and Log rank test were computed. Bivariable and multivariable Cox regression hazards models were fitted to identify the predictors of time to death. Hazard ratio with a 95% confidence interval was calculated and p-values <0.05 were considered statistically significant.

Results

In the study, the incidence density rate of neonates diagnosed with esophageal atresia was 5.5 (95% CI, 4.7–6.4) per 100-neonates day. The median time to death was 11 days (95% confidence interval (CI), 8.92–13.08). Birth weight <2500 g (adjusted hazard ratio (AHR)=1.49, 95% CI, 1.02 −2.21), having sepsis (AHR=1.67,95% CI, 1.15–2.44), being malnourished (AHR = 1.61, 95% CI, 1.03 −2.58), esophageal atretic neonates without surgery (AHR = 3.72, 95% CI, 1.34–10.38), diagnosis time at >48 hours of admission (AHR = 1.48, 95% CI, 1.01–2.15) and being dehydrated (AHR = 2.38, 95% CI, 1.63–3.46) were significant predictors of time to death among esophageal atretic neonates.

Conclusion

The findings in this study highlighted the necessity of early diagnosis, proper comorbidity treatment, and timely surgical intervention to reduce infant deaths due to esophageal atresia.

Tracheoesophageal fistula in the developing world: are we ready for thoracoscopic repair?

PURPOSE

Tracheoesophageal fistula (TEF) is a bellwether for a country's ability to care for sick newborns. We aim to review the existing literature from low- and middle-income countries in regard to management of those newborns and the possible approaches to improve their outcomes.

METHODS

A review of the existing English literature was conducted with the aim of assessing challenges faced by providers in LMIC in terms of diagnostic, preoperative, operative and post-operative care for TEF patients. We also review the limited literature for performing thoracoscopic repair in the developing world context and suggest methods for introduction of advanced thoracoscopic procedures including techniques for providing anesthesia to these challenging babies.

RESULTS

While outcomes related to technique from LMIC are comparable to the developed world, rates of secondary complications like sepsis and pneumonia are higher. In many areas, repairs are conducted in a staged fashion with minimal utilization of thoracoscopic approach. The paucity of resources creates strain on intraoperative and post-operative management.

CONCLUSION

Clearly, not all developing world contexts are ready to attempt thoracoscopic repair but we outline suggestions for assessing the existing capabilities and a stepwise gradual implementation of advanced thoracoscopy when appropriate.
