Introduction
The incidence of pediatric Wilms’ tumor (WT) is high in Africa, though patients abandon treatment after initial diagnosis. We sought to identify factors associated with WT treatment abandonment in Uganda.
Methods
A cohort study of patients < 18 years with WT in a Ugandan national referral hospital examined clinical and treatment outcomes data, comparing children whose families adhered to and abandoned treatment. Abandonment was defined as the inability to complete neoadjuvant chemotherapy and surgery for patients with unilateral WT and definitive chemotherapy for patients with bilateral WT. Patient factors were assessed via bivariate logistic regression.
Results
137 WT patients were included from 2012 to 2017. The mean age was 3.9 years, 71% (n = 98) were stage III or higher. After diagnosis, 86% (n = 118) started neoadjuvant chemotherapy, 59% (n = 82) completed neoadjuvant therapy, and 55% (n = 75) adhered to treatment through surgery. Treatment abandonment was associated with poor chemotherapy response (odds ratio [OR] 4.70, 95% confidence interval [CI] 1.30-17.0) and tumor size > 25 cm (OR 2.67, 95% CI 1.05-6.81).
Conclusions
Children with WT in Uganda frequently abandon care during neoadjuvant therapy, particularly those with large tumors with poor response. Further investigation into the factors that influence treatment abandonment and a deeper understanding of tumor biology are needed to improve treatment adherence of children with WT in Uganda.

Purpose of review
Various factors affect otolaryngology – head and neck surgery (OHNS) services in low- and middle-income countries (LMICs); including inadequate infrastructure, limited academic positions, unfavorable hospital research policies, and traditional misconceptions about gender and surgery, among others. Although gender inequalities exist globally, they are particularly pronounced in LMICs, especially in Africa.
Recent findings
A comparative narrative literature review for relevant manuscripts from January 1, 2017 to through January 10th, 2024, using PubMed, Embase and Google Scholar for articles from the United States/Canada and Africa was done. 195 relevant articles were from the United States/Canada, while only 5 were from Africa and only 1 manuscript was relevant to OHNS. The reviewed articles reported that gender disparities exist in medical training, authorship, and career advancement. We highlight possible solutions to some of these disparities to promote a more gender-diversified workforce in OHNS in Africa as well as all over the world.
Summary
Additional studies on gender disparities in Africa, are needed. These studies will highlight need for inclusive policies, structured and accessible mentorship programs; through which these disparities can be highlighted and addressed. This will in the long run ensure sustainability of OHNS care in LMICs.

Introduction
The process by which surgery residency programs select applicants is complex, opaque, and susceptible to bias. Despite attempts by program directors and educational researchers to address these issues, residents have limited ability to affect change within the process at present. Here, we present the results of a design thinking brainstorm to improve resident selection and propose this technique as a framework for surgical residents to creatively solve problems and generate actionable changes.
Methods
Members of the Collaboration of Surgical Education Fellows (CoSEF) used the design thinking framework to brainstorm ways to improve the resident selection process. Members participated in one virtual focus group focused on identifying pain points and developing divergent solutions to those pain points. Pain points and solutions were subsequently organized into themes. Finally, members participated in a second virtual focus group to design prototypes to test the proposed solutions.
Results
Sixteen CoSEF members participated in one or both focus groups. Participants identified twelve pain points and 57 potential solutions. Pain points and solutions were grouped into the three themes of transparency, fairness, and applicant experience. Members subsequently developed five prototype ideas that could be rapidly developed and tested to improve resident selection.
Conclusions
The design thinking framework can help surgical residents come up with creative ideas to improve pain points within surgical training. Furthermore, this framework can supplement existing quantitative and qualitative methods within surgical education research. Future work will be needed to implement the prototypes devised during our sessions and turn them into complete interventions.
Key message
In this paper, we demonstrate the results of a resident-led design thinking brainstorm on improving resident selection in which our team identified twelve pain points in resident selection, ideated 57 solutions, and developed five prototypes for further testing. In addition to sharing our results, we believe design thinking can be a useful framework for creative problem solving within surgical education.

Background
In 2022 there were only seven pediatric surgeons in Uganda, but approximately 170 are needed. Consequently, Ugandan general surgeons treat most pediatric surgical problems at regional hospitals. Accordingly, stakeholders created the Pediatric Emergency Surgery Course, which teaches rural providers identification, resuscitation, treatment and referral of pediatric surgical conditions. In order to improve course offerings and better understand pediatric surgery needs we collected admission and operative logbook data from four participating sites. One participating site, Lacor Hospital, rarely referred patients and had a much higher operative volume. Therefore, we sought to understand the causes of this difference and the resulting economic impact.
Methods
Over a four-year period, data was collected from logbooks at four different regional referral hospitals in Uganda. Patients ≤ 18 years old with a surgical diagnosis were included. Patient LOS, referral volume, age, and case type were compared between sites and DALYs were calculated and converted into monetary benefit.
Results
Over four sites, 8,615 admissions, and 5,457 cases were included. Lacor patients were younger, had a longer length of stay, and were referred less. Additionally, Lacor’s long-term partnerships with a high-income country institution, a missionary organization, and visiting Ugandan and international pediatric surgeons were unique. In 2018, the pediatric surgery case volume was: Lacor (967); Fort Portal (477); Kiwoko (393); and Kabale (153), resulting in a substantial difference in long-term monetary health benefit.
Conclusion
Long-term international partnerships may advance investments in surgical infrastructure, workforce, and education in low- and middle-income countries. This collaborative model allows stakeholders to make a greater impact than any single institution could make alone.

Objective
Head and neck cancer is a significant contributor to global otolaryngologic disease burden, with a disproportionate impact on low- and middle-income countries. This study investigates the factors contributing to delays in head and neck cancer diagnosis at the University Teaching Hospital of Kigali (CHUK).
Methods
Cross-sectional study of all patients with a pathologic diagnosis of head and neck cancer presenting to CHUK between January 2021 and June 2022. Sociodemographic data, tumor characteristics, and reasons for delay were collected. Univariate and multivariable analyses were undertaken to evaluate risk factors for delays.
Results
Eighty-one patients met criteria for inclusion. Median duration from patient first reported symptoms to initial medical consultation was 52 weeks, from initial medical consultation to referral to CHUK was 4 weeks, and from referral to final pathologic diagnosis was 6 weeks. The most common reason for delay to referral to CHUK was financial (37.04%). Patients who visited traditional healers had higher odds of delay between symptom onset and medical consultation (OR 3.51, CI 1.05-11.70). Delays in final diagnosis after referral were most commonly due to OR availability for biopsy (37.04%) and time for pathology results after biopsy (35.80%). OR availability had a significant impact on duration to final diagnosis (OR 59.48, CI 7.17-493.67). Stage 4 disease had the shortest time to final diagnosis (OR 0.05, CI 0.01-0.45).
Conclusion
Understanding the reasons for delayed diagnosis of head and neck cancer may help guide improvements in care, with the goal of reducing global head and neck burden of disease.

The unmet need for pediatric surgery imposes enormous health and economic consequences globally, predominantly shouldered by Sub-Saharan Africa (SSA) where children comprise almost half of the population. Lack of knowledge about the economic impact of improving pediatric surgical infrastructure in SSA inhibits the informed allocation of limited resources towards the most cost-effective interventions to bolster global surgery for children. We assessed the cost-effectiveness of installing and running two dedicated pediatric operating rooms (ORs) in a hospital in Nigeria with a pre-existing pediatric surgical service by constructing a decision tree model of pediatric surgical delivery at this facility over a year, comparing scenarios before and after the installation of the ORs, which were funded philanthropically. Health outcomes measured in disability-adjusted life years (DALYs) averted were informed by the hospital’s operative registry and prior literature. We adopted an all healthcare payor’s perspective including costs incurred by the local healthcare system, the installation (funded by the charity), and patients’ families. Costs were annualized and reported in 2021 United States dollars ($). The incremental cost-effectiveness ratios (ICERs) of the annualized OR installation and operation were presented. One-way and probabilistic sensitivity analyses were performed. We found that installing and operating two dedicated pediatric ORs averted 538 DALYs and cost $177,527 annually. The ICER of the ORs’ installation and operation was $330 per DALY averted (95% uncertainty interval [UI] 315-336) from the all healthcare payor’s perspective. This ICER was well under the cost-effectiveness threshold of the country’s half-GDP per capita in 2020 ($1043) and remained cost-effective in one-way and probabilistic sensitivity analyses. Installation of additional dedicated pediatric operating rooms in Nigeria with pre-existing pediatric surgical capacity is therefore very cost-effective, supporting investment in children’s global surgical infrastructure as an economically sound intervention.

Purpose
Intestinal obstruction caused by intestinal atresia is a surgical emergency in newborns. Outcomes for the jejunal ileal atresia (JIA), the most common subtype of atresia in low-income countries (LIC), are poor. We sought to assess the impact of utilizing the Bishop-Koop (BK) approach to JIA in improving outcomes.
Methods
A retrospective cohort study was performed on children with complex JIA (Type 2-4) treated at our national referral hospital from 1/2018 to 12/2022. BK was regularly used starting 1/1/2021, and outcomes between 1/2021 and 12/2022 were compared to those between 1/2018 and 12/2020. Statistical significance was set at p < 0.05.
Results
A total of 122 neonates presented with JIA in 1/2018-12/2022, 83 of whom were treated for complex JIA. A significant decrease (p = 0.03) was noted in patient mortality in 2021 and 2022 (n = 33, 45.5% mortality) compared to 2018-2020 (n = 35, 71.4% mortality). This translated to a risk reduction of 0.64 (95% CI 0.41-0.98) with the increased use of BK.
Conclusion
Increased use of BK anastomoses with early enteral nutrition and decreased use of primary anastomosis improves outcomes for neonates with severe JIA in LIC settings. Implementing this surgical approach in LICs may help address the disparities in outcomes for children with JIA.

Purpose
Surgery provides vital services to diagnose, treat, and palliate patients suffering from malignancies. However, despite its importance, there is little information on the delivery of surgical oncology services in Tanzania.
Methods
Operative logbooks were reviewed at all national referral hospitals that offer surgery, all zonal referral hospitals in Mainland Tanganyika and Zanzibar, and a convenience sampling of regional referral hospitals in 2022. Cancer cases were identified by postoperative diagnosis and deidentified data were abstracted for each cancer surgery. The proportion of the procedures conducted for patients with cancer and the total number of cancer surgeries done within the public sector were calculated and compared with a previously published estimate of the surgical oncology need for the country.
Results
In total, 69,195 operations were reviewed at 10 hospitals, including two national referral hospitals, five zonal referral hospitals, and three regional referral hospitals. Of the cases reviewed, 4,248 (6.1%) were for the treatment of cancer. We estimate that 4,938 cancer surgeries occurred in the public sector in Tanzania accounting for operations conducted at hospitals not included in our study. Prostate, breast, head and neck, esophageal, and bladder cancers were the five most common diagnoses. Although 387 (83%) of all breast cancer procedures were done with curative intent, 506 (87%) of patients with prostate and 273 (81%) of patients with esophageal cancer underwent palliative surgery.
Conclusion
In this comprehensive assessment of surgical oncology service delivery in Tanzania, we identified 4,248 cancer surgeries and estimate that 4,938 likely occurred in 2022. This represents only 25% of the estimated 19,726 cancer surgeries that are annually needed in Tanzania. These results highlight the need to identify strategies for increasing surgical oncology capacity in the country.

Introduction
Approximately 170 pediatric surgeons are needed for the 24 million children in Uganda. There are only seven. Consequently, general surgeons manage many pediatric surgical conditions. In response, stakeholders created the Pediatric Emergency Surgery Course (PESC) for rural providers, given three times in 2018-2019. We sought to understand the course’s long-term impact, current pediatric surgery needs, and determine measures for improvement.
Methods
In October 2021, we distributed the same test given in 2018-2019. Student’s t-test was used to compare former participants’ scores to previous scores. The course was delivered again in May 2022 to new participants. We performed a quantitative needs assessment and also conducted a focus group with these participants. Finally, we interviewed Surgeon in Chiefs at previous sites.
Results
Twenty three of the prior 45 course participants re-took the PESC course assessment. Alumni scored on average 71.9% ± 18% correct. This was higher from prior precourse test scores of 55.4% ± 22.4%, and almost identical to the 2018-2019 postcourse scores 71.9% ± 14%. Fifteen course participants completed the needs assessment. Participants had low confidence managing pediatric surgical disease (median Likert scale ≤ 3.0), 12 of 15 participants endorsed lack of equipment, and eight of 15 desired more educational resources. Qualitative feedback was positive: participants valued the pragmatic lessons and networking with in-country specialists. Further training was suggested, and Chiefs noted the need for more trained staff like anesthesiologists.
Conclusions
Participants favorably reviewed PESC and retained knowledge over three years later. Given participants’ interest in more training, further investment in locally derived educational efforts must be prioritized.

Background
The Plastic Surgery Foundation’s Surgeons in Humanitarian Alliance for Reconstruction, Research and Education (SHARE) program seeks to expand surgical capacity worldwide through mentorship and training for local plastic surgeons. This study aims to define the need for microsurgery training among SHARE global fellows and describe results of a pilot course.
Methods
Ten participants of the SHARE Virtual Microsurgical Skills Course were asked to complete an anonymous survey. Pre- and post-course response rates were 100% and 50.0%, respectively.
Results
There was a high incidence of microsurgical problems encountered in the clinical setting. Resource availability was varied, with high access to loupes (100%), yet limited access to microsurgery instruments (50%), medications (40%), operating microscope (20%), skilled nursing (0%) and appropriate peri-operative care settings (0%). Participants identified vessel preparation, instrument selection, and suture handling as priority learning objectives for a microsurgery skills course. Post-course satisfaction with learning objectives was high (60% “very good,” 40% “excellent”). Participants reported high levels of improvement in suture handling (Likert 4.60±0.55), end-to-end anastomosis (4.40±0.55), instrument selection (4.20±0.45), vessel preparation (4.20±0.45), and economy of motion (4.20±0.45).
Conclusions
This study demonstrates a high frequency of reconstructive problems encountered by global fellows yet low access to appropriate resources to perform microsurgical procedures. Initial results from a pilot virtual microsurgery course demonstrate very high satisfaction and high self-rated improvement in key microsurgical skills. The virtual course is an effective and accessible format for training surgeons in basic microsurgery skills and can be augmented by providing longitudinal opportunities for remote feedback.

The true global burden of paediatric critical illness remains unknown. Studies on children with life-threatening conditions are hindered by the absence of a common definition for acute paediatric critical illness (DEFCRIT) that outlines components and attributes of critical illness and does not depend on local capacity to provide critical care. We present an evidence-informed consensus definition and framework for acute paediatric critical illness. DEFCRIT was developed following a scoping review of 29 studies and key concepts identified by an interdisciplinary, international core expert panel (n=24). A modified Delphi process was then done with a panel of multidisciplinary health-care global experts (n=109) until consensus was reached on eight essential attributes and 28 statements as the basis of DEFCRIT. Consensus was reached in two Delphi rounds with an expert retention rate of 89%. The final consensus definition for acute paediatric critical illness is: an infant, child, or adolescent with an illness, injury, or post-operative state that increases the risk for or results in acute physiological instability (abnormal physiological parameters or vital organ dysfunction or failure) or a clinical support requirement (such as frequent or continuous monitoring or time-sensitive interventions) to prevent further deterioration or death. The proposed definition and framework provide the conceptual clarity needed for a unified approach for global research across resource-variable settings. Future work will centre on validating DEFCRIT and determining high priority measures and guidelines for data collection and analysis that will promote its use in research.

Purpose
The Pediatric Emergency Surgery Course (PESC) trains rural Ugandan providers to recognize and manage critical pediatric surgical conditions. 45 providers took PESC between 2018 and 2019. We sought to assess the impact of the course at three regional hospitals: Fort Portal, Kabale, and Kiwoko.
Methods
We conducted a retrospective cohort study. Diagnosis, procedure, and patient outcome data were collected twelve months before and after PESC from admission and theater logbooks. We also assessed referrals from these institutions to Uganda’s two pediatric surgery hubs: Mulago and Mbarara Hospitals. Wilcoxon rank-sum and Pearson’s chi-squared tests compared pre- and post-PESC measures. Interrupted time-series-analysis assessed referral volume before and after PESC.
Results
1534 admissions and 2148 cases were documented across the three regional hospitals. Kiwoko made 539 referrals, while pediatric surgery hubs received 116 referrals. There was a statistically significant immediate increase in the number of referrals from Fort Portal, from 0.5 patients/month pre-PESC to 0.8 post-PESC (95 % CI 0.03-1.51). Moving averages of the combined number of pyloromyotomy, intussusception reductions, and hernia repairs at the rural hospitals also increased post-course. Neonatal time to referral and referred patient age were significantly lower after PESC delivery.
Conclusion
Our data suggest that PESC increased referrals to tertiary centers and operative volume of selected cases at rural hospitals and shortened time to presentation at sites receiving referrals. PESC is a locally-driven, validated, clinical education intervention that improves timely care of pediatric surgical emergencies and merits further support and dissemination.

Introduction
Small bowel obstruction (SBO) is one of the most common causes for hospital admission in Ethiopia. The use of water-soluble contrast agents (WSCAs) such as Gastrografin to manage adhesive SBO can predict nonoperative resolution of SBO and reduce decision time to surgery and length of hospital stay. However, nothing is known about practice patterns and Gastrografin use in low-income settings. We sought to characterize current management practices, including use of WSCAs, as well as outcomes for patients with SBO in Addis Ababa, Ethiopia.
Methods
We conducted a mixed-methods study consisting of a survey of surgeons throughout Ethiopia and a retrospective record review at five public, tertiary care-level teaching hospitals in Addis Ababa.
Results
Of the 76 surgeons who completed the survey, 63% had heard of the use of WSCAs for SBO and only 11% used oral agents for its management. Chart review of 149 patients admitted with SBO showed the most common etiology was adhesion (39.6% of admissions), followed by small bowel volvulus (20.8%). Most patients (83.2%) underwent surgery during their admission. The most common diagnosis in patients who did not require surgery was also adhesion (68.0%), as well as for those who had surgery (33.9%), followed by small bowel volvulus (24.2%).
Conclusions
The etiology of SBO in Ethiopia may be changing, with postoperative adhesions becoming more common than other historically more prevalent causes. Although a Gastrografin protocol as a diagnostic and potentially therapeutic aid for SBO is feasible in this population and setting, challenges can be anticipated, and future studies of protocol implementation and effectiveness are needed to further inform its utility in Ethiopia and other low-income and middle-income countries.

Lack of access to pediatric medical devices and innovative technology contributes to global disparities in children’s surgical care. There are currently many barriers that prevent access to these technologies in low- and middle-income countries (LMICs). Technologies that were designed for the needs of high-income countries (HICs) may not fit the resources available in LMICs. Likewise, obtaining these devices are costly and require supply chain infrastructure. Once these technologies have reached the LMIC, there are many issues with sustainability and maintenance of the devices. Ideally, devices would be created for the needs and resources of LMICs, but there are many obstacles to innovation that are imposed by institutions in both HICs and LMICs. Fortunately, there is a growing interest for development of this space, and there are many examples of current technologies that are paving the way for future innovations. Innovations in simulation-based training with incorporated learner self-assessment are needed to fast-track skills acquisition for both specialist trainees and non-specialist children’s surgery providers, to scale up access for the larger population of children. Pediatric laparoscopy and imaging are some of the innovations that could make a major impact in children’s surgery worldwide.

Importance
Surgical infections are a major cause of perioperative morbidity and mortality, particularly in low-resource settings. Clean Cut, a 6-month quality improvement program developed by the global nonprofit organization Lifebox, has demonstrated improvements in postoperative infectious complications. However, the pilot program required intense external programmatic and resource support.
Objective
To examine the improvement in adherence to infection prevention and control standards and rates of postoperative infections in hospitals in the Clean Cut program after implementation strategies were updated and program execution was refined.
Design, setting, and participants
This cohort study evaluated and refined the Clean Cut implementation strategy to enhance scalability based on a qualitative study of its pilot phase, including formalizing programmatic and educational materials, building an automated data entry and analysis platform, and reorganizing hospital-based team composition. Clean Cut was introduced from January 1, 2019, to February 28, 2022, in 7 Ethiopian hospitals that had not previously participated in the program. Prospective data initiated on arrival in the operating room were collected, and patients were followed up through hospital discharge and with 30-day follow-up telephone calls.
Exposure
Implementation of the refined Clean Cut program.
Main outcomes and measures
The primary outcome was surgical site infection (SSI); secondary outcomes were adherence to 6 infection prevention standards, mortality, hospital length of stay, and other infectious complications.
Results
A total of 3364 patients (mean [SD] age, 26.5 [38.0] years; 2196 [65.3%] female) from 7 Ethiopian hospitals were studied (1575 at baseline and 1789 after intervention). After controlling for confounders, the relative risk of SSIs was reduced by 34.0% after program implementation (relative risk, 0.66; 95% CI, 0.54-0.81; P < .001). Appropriate Surgical Safety Checklist use increased from 16.3% to 43.0% (P < .001), surgeon hand and patient skin antisepsis improved from 46.0% to 66.0% (P < .001), and timely antibiotic administration improved from 17.8% to 39.0% (P < .001). Surgical instrument (38.7% vs 10.2%), linen sterility (35.5% vs 12.8%), and gauze counting (89.2% vs 82.5%; P < .001 for all comparisons) also improved significantly.
Conclusions and relevance
A modified implementation strategy for the Clean Cut program focusing on reduced external resource and programmatic input from Lifebox, structured education and training materials, and wider hospital engagement resulted in outcomes that matched our pilot study, with improved adherence to recognized infection prevention standards resulting in a reduction in SSIs. The demonstration of scalability reinforces the value of this SSI prevention program.

Tracheostomy is a lifesaving, essential procedure performed for airway obstruction in the case of head and neck cancers, prolonged ventilator use, and for long-term pulmonary care. While successful quality improvement interventions in high-income countries such as through the Global Tracheostomy Collaborative significantly reduced length of hospital stay and decreased levels of anxiety among patients, limited literature exists regarding tracheostomy care and practices in low and middle-income countries (LMIC), where most of the world resides. Given limited literature, this scoping review aims to summarize published tracheostomy studies in LMICs and highlight areas in need of quality improvement and clinical research efforts. Based on the PRISMA guidelines, a scoping review of the literature was performed through MEDLINE/PubMed and Embase using terms related to tracheostomy, educational and quality improvement interventions, and LMICs. Publications from 2000-2022 in English were included. Eighteen publications representing 10 countries were included in the final analysis. Seven studies described baseline needs assessments, 3 development of training programs for caregivers, 6 trialed home-based or hospital-based interventions, and finally 2 articles discussed development of standardized protocols. Overall, studies highlighted the unique challenges to tracheostomy care in LMICs including language, literacy barriers, resource availability (running water and electricity in patient homes), and health system access (financial costs of travel and follow-up). There is currently limited published literature on tracheostomy quality improvement and care in LMICs. Opportunities to improve quality of care include increased efforts to measure complications and outcomes, implementing evidence-based interventions tailored to LMIC settings, and using an implementation science framework to study tracheostomy care in LMICs.

Capnography is now recognized as an indispensable patient safety monitor. Evidence suggests that its use improves outcomes in operating rooms, intensive care units, and emergency departments, as well as in sedation suites, in postanesthesia recovery units, and on general postsurgical wards. Capnography can accurately and rapidly detect respiratory, circulatory, and metabolic derangements. In addition to being useful for diagnosing and managing esophageal intubation, capnography provides crucial information when used for monitoring airway patency and hypoventilation in patients without instrumented airways. Despite its ubiquitous use in high-income-country operating rooms, deaths from esophageal intubations continue to occur in these contexts due to incorrect use or interpretation of capnography. National and international society guidelines on airway management mandate capnography’s use during intubations across all hospital areas, and recommend it when ventilation may be impaired, such as during procedural sedation. Nevertheless, capnography’s use across high-income-country intensive care units, emergency departments, and postanesthesia recovery units remains inconsistent. While capnography is universally used in high-income-country operating rooms, it remains largely unavailable to anesthesia providers in low- and middle-income countries. This lack of access to capnography likely contributes to more frequent and serious airway events and higher rates of perioperative mortality in low- and middle-income countries. New capnography equipment, which overcomes cost and context barriers, has recently been developed. Increasing access to capnography in low- and middle-income countries must occur to improve patient outcomes and expand universal health care. It is time to extend capnography’s safety benefits to all patients, everywhere.

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.
