Management and Outcomes of Esophageal Atresia With or Without Tracheo-Esophageal Fistula Over 15 Years in South Africa.

INTRODUCTION: To determine the incidence, management and outcomes of esophageal atresia/tracheo-esophageal fistula (EA/TEF) over a 15-y period in South Africa. METHODS: A retrospective chart review of neonates with EA/TEF presenting at the main tertiary referral hospital in the KwaZulu-Natal province between 2002 and 2017 was conducted. Data collection comprised patient and maternal demographics, clinical presentations, laboratory and radiologic investigations, surgical procedures, and outcomes. A multivariate logistic regression determined the risk factors associated with mortality. RESULTS: Among 180 neonates, mean (SD) age of diagnosis was four (three) days postnatal with Gross Type C (n = 165, 92%) being the most common and the incidence was one per 10,000 live births. Majority were born term (n = 95, 53%) at peripheral hospitals (n = 167, 93%) with a mean birth weight of 2369 (736) grams. Overall HIV exposure rate was 27% (n = 48). Most (n = 138, 77%) patients presented with established pneumonia, 44% (n = 61) of whom required prolonged (>7 d) ventilator support. The median (IQR) hospital stay was 11 (8-20) d. Overall survival rate was 70% (n = 126). Birth weight <1500 g, life threatening anomalies, ventilation >30 d and postoperative sepsis contributed to mortality. CONCLUSIONS: Incidence, disease types and presentations were similar to developed countries. Despite advances in technology and neonatal care in Africa, EA/TEF surgical outcomes remain suboptimal likely due to caregivers' inability to care for these infants in disadvantaged socioeconomic circumstances with poor sanitation, etc. Research is needed to identify strategies tailored for disadvantaged communities which may contribute to improved outcomes in the perioperative and postoperative period.

Building cardiac surgical programs in lower-middle income countries.

Objectives: Medical care in low-income countries is often limited by inadequate resources, treatment facilities, and the necessary infrastructure for healthcare delivery. We hypothesized that the development of an independently functioning, internationally supported Kenyan cardiac surgical training program could address these issues through targeted investment. Methods: A review was conducted of the programmatic structure and clinical outcomes from January 2008 to October 2021 at Tenwek Hospital, Bomet, Kenya. Program development phases included (1) cardiovascular care provided by 1 full-time US board-certified cardiothoracic surgeon; (2) short-term volunteer surgical teams from the United States and Canada; and (3) development of a cardiothoracic residency program based on the Society of Thoracic Surgeons training curriculum. Patient demographics and outcomes were analyzed throughout each phase of program development. Results: A total of 817 cardiac procedures were performed during the study period, including 236 congenital (28.8%) and 581 adult (71.1%) procedures. Endemic rheumatic valvular heart disease predominated (581 patients, 62.3%). Local surgical team case volume grew over the study period, overtaking visiting team volume in 2019. Perioperative mortality was 2.1% and consistent between the visiting teams and the locally trained teams. Surgical training via a 3-year cardiothoracic residency is now in its fourth year, with the 2 graduates now retained as full-time teaching staff. Conclusions: Global health partnerships have the potential to address unmet needs in cardiac care within low- and middle-income countries. These data support the concept that acceptable clinical outcomes and consistent growth in volume can be achieved during the transition toward fully independent cardiac surgical care.

Closed Mitral Commissurotomy During Pregnancy in East Africa.

Cardiac surgeons traveling to East Africa on humanitarian surgical missions treat a large number of people of all ages with rheumatic heart disease. A patient with severe mitral stenosis with pulmonary edema in the second trimester of pregnancy was treated successfully with closed mitral commissurotomy in a hospital in rural Kenya. An operation from the late 1940s may regain prominence more than 70 years later in areas of the world with a high incidence of rheumatic heart disease and limited cardiology and cardiac surgery resources.

The Spectrum of Paediatric Intestinal Obstruction in Kenya.

INTRODUCTION: Intestinal obstruction (IO) occurs when there is impedance to the flow of intestinal contents due to a congenital or acquired pathology, and is a common paediatric surgical emergency. This study aimed to assess the pattern and outcome of paediatric IO in western Kenya. METHODS: A retrospective review of all recorded cases of mechanical IO in patients aged 15 years or below admitted at Tenwek Hospital between January 2009 and December 2013. RESULTS: The cohort included a total of 217 children (130 boys and 87 girls). The mean age was 6.7 years (range: newborn-15 years), with most (65, 30%) cases aged 1-3 years. Vomiting (161, 74.2%), abdominal pain (152, 70%), abdominal tenderness (113, 52.1%), constipation (111, 51.2%), and abdominal distension (104, 47.9%) were the predominant signs and symptoms. The most common causes of IO were ascariasis (96, 44.2%), adhesions (34, 15.7%), and intussusception (30, 13.8%). Intussusception was the leading cause of IO in children aged ≤ 1 year, ascariasis in children aged 1-5 and 6-10 years, and adhesions in children aged 11-15 years. Operative management was undertaken in 120 (55.3%) cases with 39 (32.5%) of these having gangrenous bowel. The overall mortality rate was 5%. CONCLUSION: The most common causes of mechanical bowel obstruction in this series were ascariasis, adhesions, and intussusception. Ascariasis remains a significant cause of paediatric IO in this region, thus public education, improved sanitation and deworming campaigns may be helpful in reducing the worm burden.
