In low-resource healthcare settings, the challenges faced by infants born with gastroschisis are both alarming and complex. Gastroschisis is a congenital defect that results in the intestines protruding through an opening in the abdominal wall. In affluent countries, survival rates for this condition have soared past 90% due to advanced medical technologies and neonatal care. However, in regions where healthcare resources are limited, the mortality rates for these vulnerable infants remain disturbingly high. The lack of accessible, effective medical equipment is a significant barrier to improving outcomes for these newborns.
To address this urgent need, a pioneering team of engineers and pediatric surgeons, spearheaded by the Rice360 Institute for Global Health Technologies at Rice University, has devised a groundbreaking solution known as the “SimpleSilo.” This innovative medical device is designed to provide essential treatment for gastroschisis, offering a cost-effective alternative that can be manufactured locally with readily available materials. By significantly lowering costs while maintaining functionality, the SimpleSilo represents a paradigm shift in the management of this critical condition in resource-constrained medical environments.
The ingenuity behind the SimpleSilo lies in its straightforward yet effective design. According to Vanshika Jhonsa, the first author of the published study and a recent Rice alumna, the team prioritized affordability and adaptability. The aim was to create a device that could be easily assembled using items that healthcare providers already have access to in low-resource settings. Jhonsa’s efforts were recognized with the prestigious American Pediatric Surgical Association Innovation Award, emphasizing the project’s potential impact on global health outcomes.

Standard treatment protocols typically involve the use of preformed silo bags that serve to protect the exposed intestines and gradually guide them back into the abdominal cavity. While these commercial bags are effective, they carry exorbitant costs, with single-use units priced between $200 and $300—an expense that is simply unattainable for many healthcare facilities worldwide. Although alternative methods exist, they often necessitate surgical intervention, which poses additional risks such as infection due to perforations created during the sewing process.
The SimpleSilo offers a transformative solution that mitigates these expenses without sacrificing quality of care. Composed of a saline bag, oxygen tubing, and a commercially available heat sealer, this device functions analogously to its high-cost counterparts but can be produced for less than $2.05. The assembly process is streamlined, allowing trained hospital staff to fabricate the device within an hour. This aspect of the SimpleSilo addresses both the accessibility and usability concerns prevalent in many healthcare environments, particularly in sub-Saharan Africa where traditional solutions may not be available.
In rigorous laboratory evaluations, the SimpleSilo has demonstrated remarkable performance, boasting a fluid leakage rate of only 0.02 milliliters per hour—on par with the more expensive alternatives. The device’s design has proven resilient against repeated sterilization methods, ensuring both safety and durability during its use. This testing is critical, demonstrating that the SimpleSilo can withstand the demands of real-world applications without compromising its efficacy.
The success of the SimpleSilo was further corroborated through in vitro experiments, most notably utilizing cow intestines within a mock abdominal environment. The device effectively achieved a 50% reduction of the intestines back into the cavity over three days, thereby matching the treatment outcomes typically associated with costly commercial silo bags. This data underscores the potential of the SimpleSilo to serve as a viable option in clinical settings, fulfilling the dual goals of economic and medical efficacy.
Notably, pediatric surgeons in Kenya have already begun to implement the SimpleSilo in actual patient care scenarios, reporting favorable outcomes that could herald a new chapter in the treatment of gastroschisis in low-resource settings. This clinical application reinforces the concept that the SimpleSilo is not just a theoretical solution; it is a practical intervention poised to save lives in contexts where high-cost medical devices are inaccessible.
The overarching goal of this initiative, as articulated by Bindi Naik-Mathuria, a pediatric surgeon and corresponding author of the study, is to bridge the survival gap between high-resource and low-resource settings. By making effective treatment options available and affordable, the SimpleSilo stands as a beacon of hope for many families facing the dire circumstances presented by gastroschisis.
As research moves forward, a formal clinical trial in East Africa is currently in development, aimed at further validating the SimpleSilo’s effectiveness in real-world applications. Should the results of these trials remain positive, the research team is keen to disseminate open-source instructions for the SimpleSilo, thereby empowering hospitals worldwide to manufacture their own devices. In doing so, the initiative aspires to transform healthcare delivery for infants at risk of gastroschisis in diverse environments.
The collaborative nature of this project is a testament to the power of interdisciplinarity in solving pressing global health issues. It serves as an inspiring example of how innovative engineering solutions can emerge from global collaboration and educational initiatives, particularly undergraduate projects aimed at improving health technologies. Meaghan Bond, a building lecturer and senior design engineer at Rice360, has remarked on the significance of harnessing accessible manufacturing methods and existing materials already in use in many hospitals, further illustrating the capacity for simple solutions to create profound impact.
The SimpleSilo project exemplifies a broader movement towards thinking differently about life-saving medical solutions. It highlights the necessity of contextually aware engineering and underscores the belief that even the most daunting healthcare challenges can be addressed when creativity and collaborative effort are emphasized. With the potential to close the survival gap for babies born with gastroschisis, the SimpleSilo could truly become a cornerstone of pediatric surgical care in low-resource environments, proving that thoughtful innovation can indeed save lives.
As the landscape of global health continues to evolve, the SimpleSilo’s ability to provide an affordable, effective, and easily manufacturable treatment for gastroschisis embodies the future of medical technology in resource-limited settings. Success in deploying this device could pave the way for new strategies to tackle similar healthcare disparities, reinforcing the importance of developing solutions that work within the constraints of available resources while maximizing impact.
The project is funded by Rice University, Rice360, and its generous supporters, showcasing the vital role of funding in driving meaningful research and practical applications that can transform lives in underserved communities.
