There is inadequate pediatric neurosurgical training to meet the growing burden of disease in low- and middle-income countries (LMIC). Subspecialty expertise in the management of hydrocephalus and spina bifida—two of the most common pediatric neurosurgical conditions—offers a high-yield opportunity to mitigate morbidity and avoid unnecessary death. The CURE Hydrocephalus and Spina Bifida (CHSB) fellowship offers an intensive subspecialty training program designed to equip surgeons from LMIC with the state-of-the-art surgical skills and equipment to most effectively manage common neurosurgical conditions of childhood. Prospective fellows and their home institution undergo a comprehensive evaluation before being accepted for the 8-week training period held at CURE Children’s Hospital of Uganda (CCHU) in Mbale, Uganda. The fellowship combines anatomy review, treatment paradigms, a flexible endoscopic simulation lab, daily ward and ICU rounds, radiology rounds, and clinic exposure. The cornerstone of the fellowship is the unique operative experience that includes a high volume of endoscopic third ventriculostomy with choroid plexus cauterization, myelomeningocele closure, and ventriculoperitoneal shunting, among many other procedures performed at CCHU. Upon completion, fellows return to their home institution to establish or rejuvenate a robust pediatric practice as part of a worldwide network of CHSB trainees committed to the care of underserved children. To date, the fellowship has graduated 33 surgeons from 20 different LMIC who are independently performing thousands of hydrocephalus and spina bifida operations each year.

Clinical and economic repercussions of ventricular shunt infections are magnified in low-resource countries. The efficacy of antibiotic-impregnated shunts in this setting is unclear. A previous retrospective cohort study comparing the Bactiseal Universal Shunt (BUS) and the Chhabra shunt provided clinical equipoise; thus, the authors conducted this larger randomized controlled trial in Ugandan children requiring shunt placement for hydrocephalus to determine whether there was, in fact, any advantage of one shunt over the other.
Between April 2013 and September 2016, the authors randomly assigned children younger than 16 years of age without evidence of ventriculitis to either BUS or Chhabra shunt implantation in this single-blind randomized controlled trial. The primary outcome was shunt infection, and secondary outcomes included reoperation and death. The minimum follow-up was 6 months. Time to outcome was assessed using the Kaplan-Meier method. The significance of differences was tested using Wilcoxon rank-sum, chi-square, Fisher’s exact, and t-tests.
Of the 248 patients randomized, the BUS was implanted in 124 and the Chhabra shunt in 124. There were no differences between the groups in terms of age, sex, or hydrocephalus etiology. Within 6 months of follow-up, there were 14 infections (5.6%): 6 BUS (4.8%) and 8 Chhabra (6.5%; p = 0.58). There were 14 deaths (5.6%; 5 BUS [4.0%] vs 9 Chhabra [7.3%], p = 0.27) and 30 reoperations (12.1%; 15 BUS vs 15 Chhabra, p = 1.00). There were no significant differences in the time to primary or secondary outcomes at 6 months’ follow-up (p = 0.29 and 0.17, respectively, Wilcoxon rank-sum test).
Among Ugandan infants, BUS implantation did not result in a lower incidence of shunt infection or other complications. Any recommendation for a more costly standard of care in low-resource countries must have contextually relevant, evidence-based support.

Sub-Saharan Africa (SSA) represents 17% of the world’s land, 14% of the population, and 1% of the gross domestic product. Previous reports have indicated that 81/500 African neurosurgeons (16.2%) worked in SSA—i.e., 1 neurosurgeon per 6 million inhabitants. Over the past decades, efforts have been made to improve neurosurgery availability in SSA. In this study, the authors provide an update by means of the polling of neurosurgeons who trained in North Africa and went back to practice in SSA.
Neurosurgeons who had full training at the World Federation of Neurosurgical Societies (WFNS) Rabat Training Center (RTC) over the past 16 years were polled with an 18-question survey focused on demographics, practice/case types, and operating room equipment availability.
Data collected from all 21 (100%) WFNS RTC graduates showed that all neurosurgeons returned to work to SSA in 12 different countries, 90% working in low-income and 10% in lower-middle-income countries, defined by the World Bank as a Gross National Income per capita of ≤ US$995 and US$996–$3895, respectively. The cumulative population in the geographical areas in which they practice is 267 million, with a total of 102 neurosurgeons reported, resulting in 1 neurosurgeon per 2.62 million inhabitants. Upon return to SSA, WFNS RTC graduates were employed in public/private hospitals (62%), military hospitals (14.3%), academic centers (14.3%), and private practice (9.5%). The majority reported an even split between spine and cranial and between trauma and elective; 71% performed between 50 and more than 100 neurosurgical procedures/year. Equipment available varied across the cohort. A CT scanner was available to 86%, MRI to 38%, surgical microscope to 33%, endoscope to 19.1%, and neuronavigation to 0%. Three (14.3%) neurosurgeons had access to none of the above.
Neurosurgery availability in SSA has significantly improved over the past decade thanks to the dedication of senior African neurosurgeons, organizations, and volunteers who believed in forming the new neurosurgery generation in the same continent where they practice. Challenges include limited resources and the need to continue expanding efforts in local neurosurgery training and continuing medical education. Focus on affordable and low-maintenance technology is needed.
