Surgical treatment outcome of children with neural-tube defect: A prospective cohort study in a high volume center in Addis Ababa, Ethiopia.

Introduction: Prevalence of neural tube defects (NTD) is high thus many children are born with a neural tube defect in Addis Ababa, and surgical closure is a commonly performed procedure at the pediatric neurosurgical specialty center. Research question: The primary aim is to study the outcomes in children undergoing surgical closure of NTDs and to identify risk factors for readmission, complications and mortality. Material and methods: Single-center prospective study of all surgically treated NTDs from April 2019 to May 2020. Results: A total of 228 children, mean age 11 days (median 4) underwent surgery during the study period. There were no in-hospital deaths. Perioperatively 11 (4.8%) children developed wound complications, none of them needed surgery and there was no perioperative mortality. The one-year follow-up rate was 62.7% (143/228) and neurological status remained stable since discharge in all. The readmission and reoperation rates were 38 % and 8 % and risk factors for readmission were hydrocephalus (80%) and open defects (88%). Hydrocephalus (P = 0.05) and younger age (P = 0.02) were identified as risk factors for mortality. The wound-related complication rate was 55% at and was associated with large defects (P = 0.04) and delayed closure due to late hospital presentation (P = 0.01). Discussion and conclusion: The study reveals good perioperative surgical outcome and further need for systematic improvement in treatment and follow-up of NTD patients especially with hydrocephalus. We identified risk factors for wound-related complications, readmission and mortality.

Prospective Study of Surgery for Traumatic Brain Injury in Addis Ababa, Ethiopia: Trauma Causes, Injury Types, and Clinical Presentation.

BACKGROUND: Traumatic brain injury (TBI) is a public health problem in Ethiopia. More knowledge about the epidemiology and neurosurgical management of TBI patients is needed to identify possible focus areas for quality improvement and preventive efforts. METHODS: This prospective cross-sectional study (2012-2016) was performed at the 4 teaching hospitals in Addis Ababa, Ethiopia. All surgically treated TBI patients were included, and data on clinical presentation, injury types, and trauma causes were collected. RESULTS: We included 1087 patients (mean age 29 years; 8.7% females; 17.1% <18 years old). Only 15.5% of TBIs were classified as severe (Glasgow Coma Scale score 3-8). Depressed skull fracture (44.9%) and epidural hematoma (39%) were the most frequent injuries. Very few patients had polytrauma (3.1%). Assault was the most common injury mechanism (69.9%) followed by road traffic accidents (15.8%) and falls (8.1%). More than 80% of patients came from within 200 km of the hospitals, but the median time to admission was 24 hours. Most assault victims (80.4%) were injured >50 km from the hospitals, whereas 46% of road traffic accident victims came from the urban area. Delayed admission was associated with higher Glasgow Coma Scale scores and nonsevere TBI (P < 0.01). CONCLUSIONS: The injury panorama, delayed admission, and small number of operations performed for severe TBI are linked to a substantial patient selection bias both before and after hospital admission. Our results also suggest that there should be a geographical framework for tailored guidelines, preventive efforts, and development of prehospital and hospital services.

Four-Year Treatment Outcomes of Children Operated for Neural Tube Defect in Addis Ababa, Ethiopia: A Retrospective Study.

BACKGROUND: Closure of neural tube defects (NTDs) in children is a common neurosurgical procedure in Ethiopia, but we know little about the outcomes. The aim of this study was to study outcomes and to identify predictors of mortality and morbidity of surgically treated NTDs. METHODS: Between July 2013 and August 2014, all patients operated for NTDs were prospectively registered in a database and followed for a minimum of 4 years after the initial surgery. RESULTS: A total of 88 children primary operated for NTD closure in the period between July 2013 to August 2014 were included in the study. The median age at primary NTD closure was 29 days. The commonest site of defect was lumbar (60.2%) followed by lumbosacral (11.4%). There was no perioperative mortality, however, 23 (26.1%) of the children developed wound-related complications including cerebrospinal fluid leak and infection. Preoperative cerebrospinal fluid leakage (P = 0.013) was associated with risk of postoperative complications. We acquired 4-years follow-up data for 61 (69%) of the cases. At 4 years, 25 (41%) of these children had died. Presence of hydrocephalus and reduced motor function were found to be negative predictors for survival. CONCLUSIONS: Overall, the prognosis was poor. The study provides a basis for identifying patients at risk to improve the standard of care.
