Profile of neural tube defects in pediatric patients in Nigeria: A systematic review.

Since the 2015 Lancet Commission on Global Surgery report, interest in addressing global surgical health inequities has grown. Neural tube defects (NTDs) pose significant challenges in low- and middle-income countries (LMICs), including Nigeria, due to inconsistent/ineffective folate supplementation and limited healthcare access. This systematic review examines trends in the presentation, management, and outcomes of NTDs in Nigeria.A systematic review, conducted following PRISMA guidelines, included studies on NTDs in Nigeria from 1962 to 2023. Extracted data covered publication year, patient demographics, folate use, NTD type and location, diagnosis, treatment modality, post-treatment complications, and mortality. Temporal trends were analyzed by decade from the 1960 s to the 2020 s.A total of 63 studies involving 3,390 patients with NTDs were identified. Myelomeningocele was the most common defect, predominantly affecting the lumbosacral region. Folate usage improved from 12.5% (1990-99) to 60.9% (2020-23). Mortality trends initially fluctuated, rising from 14.4% (1960-69) to 33.3% (1990-99) before significantly declining to 9.3% (2000-09), 4.6% (2010-19), and 6.0% (2020-23).The management of NTDs in Nigeria has seen some notable developments, particularly in mortality and increased folate supplementation. However, challenges persist in achieving consistent prevention through timely folate supplementation and addressing residual disparities in care. Ongoing research and targeted public health strategies are essential to sustain progress and improve outcomes for NTDs in Nigeria.
