Abstract
INTRODUCTION The management of gastroschisis remains problematic in low- and middle-income countries with high perioperative mortality. The objective of this work was to make an initial assessment of our management of gastroschisis. MATERIALS AND METHODS This was a monocentric and cross-sectional study including all newborns with gastroschisis between January 2017 and December 2021 in the Pediatric Surgery and Anesthesia Resuscitation Department of the Aristide Le Dantec University Hospital Center from Dakar. The socio-demographic, diagnostic, therapeutic and evolutionary parameters were studied. RESULTS Eighteen cases of gastroschisis (11 males and 7 females). The mothers' mean age were 23.1 ± 5.7 years old. Only one antenatal diagnosis was made. The mean gestation age were 36.5 ± 1.5 weeks. On admission, the mean age was 16.8 ± 6.3 h and the mean weight 2244 ± 260.3 g. Gastroschisis was complex in four patients. Primary bowel reintegration was performed in 8 cases (44.4%) and progressive reintegration using an Applied Alexis retractor in 9 newborns (55.6%). Main complications were respiratory distress (28.3%) and sepsis (22.2%). The mean duration of return of oral feeding was 5.1 ± 1.9 days. Mortality was 94.4% (17/18). CONCLUSION Reducing gastroschisis-related mortality in our low-income countries remains a major challenge.

Abstract
This review explores the significant advancements in paediatric surgery in Africa during the twenty-first century, with a particular focus on capacity-building, education, infrastructural development, and research. Historically, paediatric surgery has been an overlooked sector, especially in low-and-middle-income countries in Africa. However, recent years have seen considerable progress. Collaborative efforts such as the Global Initiative for Children's Surgery, and the formation of the Pan African Paediatric Surgery Association, the College of Surgeons of East, Central and Southern Africa and the West African College of Surgeons have facilitated knowledge sharing, collaboration, and advocacy for enhancing surgical standards. Local training programmes, including Master of Medicine programmes and fellowships, have been instrumental in building a skilled workforce. These initiatives have been complemented by infrastructural developments through non-governmental organisations like Kids Operating Room, which have expanded access to paediatric surgical care. Technological advancements, particularly in telemedicine, have further enhanced accessibility. Task-sharing strategies, where non-specialist physicians are trained in paediatric surgical skills, have also been utilised to address the shortage of specialised surgeons. Research in paediatric surgery has experienced an upswing, with local health professionals taking the lead. Research has been crucial for understanding the epidemiology of paediatric surgical conditions, and developing prevention strategies, and is increasingly leading to the inclusion of paediatric surgery in national health plans. Despite the progress, challenges remain, including the need for sustainable funding, continued investment in infrastructure, and training and retention of healthcare professionals. The review emphasises the importance of ongoing efforts in community engagement, innovative technologies, and health systems strengthening for the sustainable development of paediatric surgical services in Africa.

Abstract
BACKGROUND Gastroschisis causes near complete mortality in low-income countries (LICs). This study seeks to understand the impact of bedside bowel reduction and silo placement, and protocolized resuscitation on gastroschisis outcomes in LICs. METHODS We conducted a retrospective cohort study of gastroschisis patients at a tertiary referral center in Kampala, Uganda. Multiple approaches for bedside application of bowel coverage devices and delayed closure were used: sutured urine bags (2017-2018), improvised silos using wound protectors (2020-2021), and spring-loaded silos (2022). Total parental nutrition (TPN) was not available; however, with the use of improvised silos, a protocol was implemented to include protocolized resuscitation and early enteral feeding. Risk ratios (RR) for mortality were calculated in comparison to historic controls from 2014. RESULTS 368 patients were included: 42 historic controls, 7 primary closures, 81 sutured urine bags, 133 improvised silos and 105 spring-loaded silos. No differences were found in sex (p = 0.31), days to presentation (p = 0.84), and distance traveled to the tertiary hospital (p = 0.16). Following the introduction of bowel coverage methods, the proportion of infants that survived to discharge increased from 2% to 16-29%. In comparison to historic controls, the risk of mortality significantly decreased: sutured urine bags 0.65 (95%CI: 0.52-0.80), improvised silo 0.76 (0.66-0.87), and spring-loaded silo 0.65 (0.56-0.76). CONCLUSION Bedside application of bowel coverage and protocolization decreases the risk of death for infants with gastroschisis, even in the absence of TPN. Further efforts to expand supply of low-cost silos in LICs would significantly decrease the mortality associated with gastroschisis in this setting. TYPE OF STUDY Treatment Study. LEVEL OF EVIDENCE III (Retrospective Comparative Study).

Gastroschisis in Sub-Saharan Africa: a scoping review of the prevalence, management practices, and associated outcomes. Pediatr Surg Int 2023; 39:246. [PMID: 37584727 DOI: 10.1007/s00383-023-05531-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Accepted: 07/30/2023] [Indexed: 08/17/2023]
Abstract
Gastroschisis is a congenital defect of the anterior abdominal wall characterized by a periumbilical abdominal wall defect with associated bowel protrusion. Limitations in the diagnosis and management of gastroschisis in Sub-Saharan African countries contribute to the high mortality rate. Few studies have been published despite its significant contribution to neonatal mortality in Sub-Saharan Africa. This review study explores the prevalence of gastroschisis, likewise the management and clinical outcomes. Full-text articles reporting the prevalence, management, and associated outcomes of gastroschisis in Sub-Saharan Africa were included. Data were extracted from databases such as PubMed, Google Scholar, and Ajol following a systematic search. The study was reported following the PRISMA-ScR guideline. A total of ten articles which included studies conducted from 1999 to 2022 fulfilled the criteria. The prevalence of gastroschisis varied widely, ranging from 0.026 to 1.75 with an overall mortality rate of 62.48%. Young maternal age is strongly associated with the incidence of gastroschisis. The study showed a slight male preponderance with a M: F ratio of 1.12:1. Staged closure with silos is the preferred method of management, it is explicitly linked to improved clinical outcomes. The prevalence rate and associated mortality of gastroschisis remain alarmingly high in most of the studies. There is a need for advanced diagnostic and management practices as well as increased awareness of gastroschisis to reduce mortality and improve survival outcomes.

The burden, prevention and care of infants and children with congenital anomalies in sub-Saharan Africa: A scoping review. PLOS GLOBAL PUBLIC HEALTH 2023; 3:e0001850. [PMID: 37379291 PMCID: PMC10306220 DOI: 10.1371/journal.pgph.0001850] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/24/2022] [Accepted: 03/17/2023] [Indexed: 06/30/2023]
Abstract
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.

Abstract
BACKGROUND Mortality from perforated peptic ulcer disease (PUD) remains high, especially in sub-Saharan Africa. We sought to identify predictors of mortality following surgery for perforated PUD. METHODS We performed a retrospective study of acute care surgeries at Kamuzu Central Hospital (KCH) in Malawi from 2013 to 2022. Patients undergoing omental patch surgeries were included. Bivariate and multivariate analyses were used to model predictors of mortality. RESULTS A total of 248 patients were included. The mean age was 30 ± 15 years. Ninety percent were male. Mortality rate was 22.2%. Predictors of mortality included age (adjusted odds ratio [AOR] 1.06, 95% confidence interval [CI] 1.03-1.09), shock index (AOR 1.86, 95% CI 1.14-3.03), days to operative intervention (AOR 1.44, 95% CI 1.10-1.88), and presence of complications (AOR 9.65, 95% CI 3.79-24.6). CONCLUSIONS Mortality following surgery for perforated PUD remains high in this low-resource environment. In-hospital delay is a significant and modifiable predictor of mortality.

Abstract
BACKGROUND Gastroschisis mortality in sub-Saharan Africa (SSA) remains high at 59-100%. Silo inaccessibility contributes to this disparity. Standard of care (SOC) silos cost $240, while median monthly incomes in SSA are < $200. Our multidisciplinary American and Ugandan team designed and bench-tested a low-cost (LC) silo that costs < $2 and is constructed from locally available materials. Here we describe in vivo LC silo testing. METHODS A piglet gastroschisis model was achieved by eviscerating intestines through a midline incision. Eight piglets were randomized to LC or SOC silos. Bowel was placed into the LC or SOC silo, maintained for 1-h, and reduced. Procedure times for placement, intestinal reduction, and silo removal were recorded. Tissue injury of the abdominal wall and intestine was assessed. Bacterial and fungal growth on silos was also compared. RESULTS There were no gross injuries to abdominal wall or intestine in either group or difference in minor bleeding. Times for silo application, bowel reduction, and silo removal between groups were not statistically or clinically different, indicating similar ease of use. Microbiologic analysis revealed growth on all samples, but density was below the standard peritoneal inoculum of 105 CFU/g for both silos. There was no significant difference in bacterial or fungal growth between LC and SOC silos. CONCLUSION LC silos designed for manufacturing and clinical use in SSA demonstrated similar ease of use, absence of tissue injury, and acceptable microbiology profile, similar to SOC silos. The findings will allow our team to proceed with a pilot study in Uganda.

Abstract
OBJECTIVE This study aimed to verify risk factors associated with gastroschisis mortality in three neonatal intensive care units located in the state of Espírito Santo, Brazil. METHODS A retrospective cohort study of neonates with gastroschisis was performed between 2000 and 2018. Prenatal, perinatal, and postsurgical variables of survival or nonsurvival groups were compared using chi-square statistical test, t-test, Mann-Whitney U test, and logistic regression. Tests with p<0.05 were considered statistically determined. RESULTS A total of 142 newborns were investigated. Mean maternal age, gestational age, and birth weight were lower in the group of nonsurvival (p<0.05). Poor clinical conditions during admission, complex gastroschisis, closure with silo placement, the use of blood products, surgical complications, and short bowel syndrome were more frequent in the nonsurvival group (p<0.05). Complex gastroschisis [adjusted odds ratio (OR) 3.74, 95% confidence interval (95%CI) 1.274-11.019] and short bowel syndrome (adjusted OR 7.55, 95%CI 2.177-26.225) increased the risk of death. Higher birth weight inversely reduced the risk for mortality (adjusted OR 0.99, 95%CI 0.997-1.000). CONCLUSION Complex gastroschisis and short bowel syndrome increased the risk of death, with greater birth weight being inversely correlated with the risk of mortality. The findings of this research can contribute to the formulation of protocols to improve the quality and safety of care in order to reduce neonatal mortality associated with gastroschisis.

Abstract
OBJECTIVES To systematically review existing literature on hospital-based quality improvement studies in sub-Saharan Africa that aim to improve surgical and anaesthesia care, capturing clinical, process and implementation outcomes in order to evaluate the impact of the intervention and implementation learning. DESIGN We conducted a systematic literature review and narrative synthesis. SETTING Literature on hospital-based quality improvement studies in sub-Saharan Africa reviewed until 31 December 2021. PARTICIPANTS MEDLINE, EMBASE, Global Health, CINAHL, Web of Science databases and grey literature were searched. INTERVENTION We extracted data on intervention characteristics and how the intervention was delivered and evaluated. PRIMARY AND SECONDARY OUTCOME MEASURES Importantly, we assessed whether clinical, process and implementation outcomes were collected and separately categorised the outcomes under the Institute of Medicine quality domains. Risk of bias was not assessed. RESULTS Of 1573 articles identified, 49 were included from 17/48 sub-Saharan African countries, 16 of which were low-income or lower middle-income countries. Almost two-thirds of the studies took place in East Africa (31/49, 63.2%). The most common intervention focus was reduction of surgical site infection (12/49, 24.5%) and use of a surgical safety checklist (14/49, 28.6%). Use of implementation and quality improvement science methods were rare. Over half the studies measured clinical outcomes (29/49, 59.2%), with the most commonly reported ones being perioperative mortality (13/29, 44.8%) and surgical site infection rate (14/29, 48.3%). Process and implementation outcomes were reported in over two thirds of the studies (34/49, 69.4% and 35, 71.4%, respectively). The most studied quality domain was safety (44/49, 89.8%), with efficiency (4/49, 8.2%) and equitability (2/49, 4.1%) the least studied domains. CONCLUSIONS There are few hospital-based studies that focus on improving the quality of surgical and anaesthesia care in sub-Saharan Africa. Use of implementation and quality improvement methodologies remain low, and some quality domains are neglected. PROSPERO REGISTRATION NUMBER CRD42019125570.

J Pediatr Surg 2022; 57:1664-1670. [PMID: 34749982 DOI: 10.1016/j.jpedsurg.2021.09.041] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2021] [Revised: 09/08/2021] [Accepted: 09/21/2021] [Indexed: 11/26/2022]
Abstract
BACKGROUND Gastroschisis is a common birth defect with < 5% mortality in high income countries, but mortality in sub Saharan Africa remains high. We sought to compare gastroschisis management strategies and patient outcomes at tertiary pediatric referral centers in the United States and Kenya. METHODS This retrospective chart review examined uncomplicated gastroschisis patients treated at Riley Hospital for Children in Indianapolis, USA (n = 110), and Shoe4Africa Children's Hospital in Eldoret, Kenya (n = 75), from 2010 to 2018. Analyzed were completed using Chi square, Fisher's exact, and independent samples t tests and medians tests at the 95% significance level. RESULTS Survival in the American cohort was double that of the Kenyan cohort (99.1% vs 45.3%, p< 0.001). Sterile bag use for bowel containment was lower in Kenya (81.3% vs 98.1%, p< 0.001), but silo use was comparable at both institutions (p = 0.811). Kenyan patients had earlier median enteral feeding initiation (4vs 10 days, p< 0.001) and accelerated achievement of full enteral feeding (10vs 23 days, p< 0.001), but none received TPN. Despite earlier feeding, Kenyan patients displayed a higher prevalence of wound infections (70.8% vs 17.1%, p< 0.001) and sepsis (43.9% vs 4.8%, p< 0.001). In Kenya, survivors and non survivors displayed no difference in sterile bag use, hemodynamic stability, all cause infection rates, or antibiotic free hospital days. Defect closure (p< 0.001) and enteral feeding initiation (p< 0.001) were most predictive of survival. CONCLUSION Improving immediate response strategies for gastroschisis in Kenya could improve survival and decrease infection rates. Care strategies in the US can center on earlier enteral feeding initiation to reduce time to full feeding. LEVEL OF EVIDENCE Level III.

Abstract
OBJECTIVE To analyze gastroschisis annual incidence, mortality rates, and trends in the Brazilian state of Rio Grande do Sul from the year 2000 to the year 2017. METHOD Population-based study with the analysis of the temporal trend of gastroschisis annual incidence and mortality rates. Data were obtained from the Live Birth Information System and the Mortality Information System, with the analysis performed by polynomial regression modeling. RESULTS There were 2,612,532 live births, 705 hospitalizations, and 233 deaths due to gastroschisis. The annual incidence of gastroschisis was 2.69 per 10,000 live births. The annual incidence rate increased by 85% in the total period (p = 0.003), and mortality was 33% in the 2000-2017 period. Maternal age < 25 years was a risk factor for gastroschisis (p < 0.001). Children were more likely to be born weighing < 2,500 g (p < 0.001) and with a gestational age < 37 weeks (p < 0.001). The annual incidence trend was to increase, and the mortality trend was to decrease. CONCLUSION Similar to what has been described in several regions/countries, there was a trend showing an 85% increase in the annual incidence of gastroschisis (p = 0.003) and the mortality was 33% with a trend of decreasing (p = 0.002).

Abstract
OBJECTIVE To characterize the influence of birthplace on outcomes of patients with gastroschisis admitted to three hospitals in a state in Brazil's southeastern region, according to condition inborn (born in a reference center) or outborn (born outside the reference center). METHODS Retrospective multicenter cohort study of patients with gastroschisis. The sample size utilized was of patients admitted in three hospitals with a diagnosis of gastroschisis ICD 10 Q79.3 between January 2000 to December 2018. Patients were divided into two groups, inborn and outborn. Characteristics of prenatal, perinatal and postoperative were compared using statistical tests. The level of significance adopted was P-value < 0.05. RESULTS In total, 144 cases of gastroschisis were investigated. The outborn patients group had higher rates of absence of antenatal diagnosis (p = 0.001), vaginal delivery (p = 0.001), longer time between birth and abdominal wall closure surgery (p = 0.001), to silo removal (p = 0.001), to first enteral feeding (p = 0.008), for weaning from mechanical ventilation (p = 0.034), used less peripherally inserted central catheter (PICC) and required more venous dissections (p = 0.001), and lower mean of serum sodium (p = 0.015). There were no differences in mortality rates and length of hospital stay between the inborn and outborn groups. CONCLUSION Although outborn patients with gastroschisis were less likely to have an antenatal diagnosis and were more prone to a longer time to undergo surgical and feeding procedures, and to spend more time in mechanical ventilation, these disadvantages seemed not to reflect on the death rate and the length of hospital stay of patients from this group.

Abstract
BACKGROUND The lack of access to essential surgery for many of our world's children is a global health crisis. A third of all deaths in the pediatric population are due to surgical conditions. In low- and middle-income countries, an average of nine in ten children lack access to basic surgical care. METHODS This review examines ten commitment statements ratified by numerous global pediatric surgical organizations aimed at addressing existing gaps in global surgical care for children. They are substantiated by a review of literature and represent over-arching principles. RESULTS They prompt the recognition of childhood surgical disease as a global health priority and advocate for availability to safe surgical and anesthetic care. Calls to action highlight the importance of capacity building in the areas of education, data gathering, workforce, research, and international collaborations. DISCUSSION Eventually, there is the hope for widespread approval of the guiding principles they represent and that the statements themselves, as encapsulations of these beliefs, may act as a continued call for advocacy and action for the necessary work, resources, and funding to mitigate global pediatric surgical disparities.

Abstract
BACKGROUND Low- and middle-income countries like Uganda face a severe shortage of pediatric surgeons. Most children with a surgical emergency are treated by nonspecialist rural providers. We describe the design and implementation of a locally driven, pilot pediatric emergency surgical care course to strengthen skills of these providers. This is the first description of such a course in the current literature. METHODS The course was delivered three times from 2018 to 2019. Modules include perioperative management, neonatal emergencies, intestinal emergencies, and trauma. A baseline needs assessment survey was administered. Participants in the second and third courses also took pre and postcourse knowledge-based tests. RESULTS Forty-five providers representing multiple cadres participated. Participants most commonly perform hernia/hydrocele repair (17% adjusted rating) in their current practice and are least comfortable managing cleft lip and palate (mean Likert score 1.4 ± 0.9). Equipment shortage was identified as the most significant challenge to delivering pediatric surgical care (24%). Scores on the knowledge tests improved significantly from pre- (55.4% ± 22.4%) to postcourse (71.9% ± 14.0%, p < 0.0001). CONCLUSION Nonspecialist clinicians are essential to the pediatric surgical workforce in LMICs. Short, targeted training courses can increase provider knowledge about the management of surgical emergencies. The course has spurred local surgical outreach initiatives. Further implementation studies are needed to evaluate the impact of the training. LEVEL OF EVIDENCE V.

Abstract
Silo bags are synthetic, flexible silicone bags used to cover and protect the bowel of neonates born with gastroschisis. They are transparent, which enables clinicians to visualise bowel colour and allows for gentle reduction until closure. Silo bags are expensive, and different sizes are needed depending on the gastroschisis size. Currently, tertiary hospitals in low-income countries experience great difficulty in purchasing these bags. Therefore, in this article, we present a method for creating a preformed silo bag by utilising readily available disposable equipment in secondary or tertiary hospitals. The disposable equipment required includes a 200- or 500-ml saline or blood bag, 16- or 18-Fr silicone/latex Foley catheter, Opsite® and 2-0 silk suture. The saline bag is cut and opened transversely. The Foley catheter is cut corresponding to the diameter of the saline bag opening, and both ends of the catheter piece are connected to each other to create a 'circle', which is used as the base for the opening. The edge of the saline bag is turned inside out around the catheter and then securely closed with a continuous suture, which fixes the folded part of the bag to the catheter. These silo bags are cheap and easily and quickly prepared at any centre in Africa and very similar to manufactured silo bags, which are comparatively costly and difficult to procure in limited-resource environments.

Multidisciplinary Development of a Low-Cost Gastroschisis Silo for Use in Sub-Saharan Africa. J Surg Res 2020; 255:565-574. [PMID: 32645490 DOI: 10.1016/j.jss.2020.05.037] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/13/2019] [Revised: 04/01/2020] [Accepted: 05/03/2020] [Indexed: 01/24/2023]
Abstract
BACKGROUND Gastroschisis silos are often unavailable in sub-Saharan Africa (SSA), contributing to high mortality. We describe a collaboration between engineers and surgeons in the United States and Uganda to develop a silo from locally available materials. METHODS Design criteria included the following: < $5 cost, 5 ± 0.25 cm opening diameter, deformability of the opening construct, ≥ 500 mL volume, ≥ 30 N tensile strength, no statistical difference in the leakage rate between the low-cost silo and preformed silo, ease of manufacturing, and reusability. Pugh scoring matrices were used to assess designs. Materials considered included the following: urine collection bags, intravenous bags, or zipper storage bags for the silo and female condom rings or O-rings for the silo opening construct. Silos were assembled with clothing irons and sewn with thread. Colleagues in Uganda, Malawi, Tanzania, and Kenya investigated material cost and availability. RESULTS Urine collection bags and female condom rings were chosen as the most accessible materials. Silos were estimated to cost < $1 in SSA. Silos yielded a diameter of 5.01 ± 0.11 cm and a volume of 675 ± 7 mL. The iron + sewn seal, sewn seal, and ironed seal on the silos yielded tensile strengths of 31.1 ± 5.3 N, 30.1 ± 2.9 N, and 14.7 ± 2.4 N, respectively, compared with the seal of the current standard-of-care silo of 41.8 ± 6.1 N. The low-cost silos had comparable leakage rates along the opening and along the seal with the spring-loaded preformed silo. The silos were easily constructed by biomedical engineering students within 15 min. All silos were able to be sterilized by submersion. CONCLUSIONS A low-cost gastroschisis silo was constructed from materials locally available in SSA. Further in vivo and clinical studies are needed to determine if mortality can be improved with this design.
