Introduction:

Asia's healthcare systems are among the most diverse in the world. While advanced minimally invasive surgery (MIS) is routine in major metropolitan hospitals, millions of people living in rural and underserved regions continue to face limited access to safe surgical care. High equipment costs, infrastructure requirements, workforce shortages, and long travel distances often force patients to choose between delayed treatment, open surgery, and no surgery at all.

As countries across Asia strive toward universal health coverage, there is growing recognition that surgical innovation must be affordable, scalable, and adapted to local realities. This has given rise to a new generation of frugal, minimally invasive technologies designed specifically for resource-constrained environments.

Rather than attempting to replicate expensive Western surgical ecosystems, these innovations rethink surgery from first principles, eliminating unnecessary complexity while preserving safety and effectiveness. Emerging largely from India and increasingly adopted across Asia and Africa, frugal MIS technologies are demonstrating that high-quality surgery can be delivered at lower cost, with lower energy consumption and broader accessibility.

The Access Challenge

The Lancet Commission on Global Surgery highlighted that billions of people worldwide lack access to safe, affordable surgical care. Across Asia, the challenge is particularly evident in rural districts where hospitals often struggle with unreliable electricity, limited biomedical engineering support, shortages of specialist anaesthesia providers, and constrained budgets.

Conventional laparoscopic surgery requires carbon dioxide insufflation systems, laparoscopic towers, high-powered light sources, specialised monitors, and a steady supply chain for maintenance and consumables. These requirements make deployment difficult outside major urban centres.

For many district hospitals, the result is a continued reliance on open surgery, leading to longer hospital stays, increased postoperative pain, delayed return to work, and higher indirect costs for patients and families.

Gas Insufflation-Less Laparoscopic Surgery (GILLS)

One of the most significant frugal innovations emerging from Asia is Gas Insufflation-Less Laparoscopic Surgery (GILLS), developed and implemented in rural India.

Traditional laparoscopy relies on carbon dioxide pneumoperitoneum to create a working space within the abdomen. GILLS replaces this with a simple mechanical abdominal wall lift system that elevates the abdominal wall without requiring gas insufflation.

The concept may appear simple, but its implications are profound.

By eliminating carbon dioxide insufflation, hospitals avoid the costs and logistics associated with gas cylinders and insufflators. Procedures can frequently be performed under spinal anaesthesia rather than general anaesthesia, reducing both costs and workforce requirements while improving access in settings where anaesthesia specialists may be limited.

Clinical studies have demonstrated that gasless laparoscopy can achieve outcomes comparable to conventional laparoscopy for selected procedures while maintaining acceptable complication and conversion rates. Researchers have also demonstrated its cost-effectiveness in rural hospitals and its ability to expand access to minimally invasive surgery where conventional systems are difficult to sustain.

Perhaps most importantly, GILLS allows surgeons to combine familiar open surgical instruments with laparoscopic techniques, reducing barriers to adoption and shortening the learning curve.

Portable Imaging: Beyond the Laparoscopic Tower

Visualisation remains central to minimally invasive surgery. However, conventional laparoscopic towers are among the most expensive and energy-intensive components of the surgical ecosystem.

To address this challenge, innovators have developed portable digital imaging systems such as the Laptop Cystoscope and the newer Dual Digital Scope platform. These systems replace bulky tower infrastructure with compact digital cameras powered directly through a laptop, tablet, or smartphone.

The result is a plug-and-play imaging solution that dramatically reduces equipment costs and power consumption.

Images can be displayed on standard monitors, projectors, or smart televisions, making the technology suitable for district hospitals, outreach programmes, and mobile surgical units. The systems can be used for cystoscopy, laparoscopy, training, and other endoscopic applications.

Importantly, the Laptop Cystoscope has been recognised in the WHO Compendium of Innovative Health Technologies for Low-Resource Settings, highlighting its potential to improve access to endoscopic services in underserved regions.

Rethinking Surgical Training

Technology alone does not improve surgical access. Skilled healthcare professionals remain essential.

One of the biggest barriers to expanding minimally invasive surgery is the concentration of training opportunities within urban academic centres. Rural surgeons often face significant costs and workforce disruption when required to travel for extended training programmes.
To overcome this, realistic full-procedural simulators that replicate complete surgical procedures rather than isolated technical tasks are available.

These simulators allow trainees to practice Caesarean sections, gasless laparoscopy, cystoscopy, appendicectomy, ovarian surgery, and other procedures using the same instruments employed in real clinical settings.

Unlike many high-cost virtual reality systems, frugal simulators are affordable, repairable, and designed for repeated use. Their portability enables training in rural hospitals, ensuring that surgeons learn in the environments where they will ultimately practice.

Clinical and Economic Benefits

Evidence from implementation programmes demonstrates that frugal MIS technologies can generate substantial clinical and economic benefits.

Patients benefit from smaller incisions, reduced postoperative pain, shorter hospital stays, and faster return to work. Hospitals benefit from lower equipment costs, reduced maintenance requirements, and improved utilisation of operating rooms.

Several rural hospitals that have implemented gasless laparoscopy have reported substantial increases in surgical volumes following training programmes. By enabling local treatment, these innovations reduce costly referrals and decrease the financial burden on patients who would otherwise need to travel long distances to tertiary centres.

For health systems operating under increasing financial pressure, such technologies represent an opportunity to expand services without major capital investments.

The Future of Frugal MIS in Asia

The next phase of development is likely to involve integration with tele-mentoring, artificial intelligence, cloud-based learning platforms, and regional manufacturing ecosystems.

India is emerging as a major hub for frugal medical innovation, with increasing opportunities to export technologies and training models to other low- and middle-income countries. Similar approaches could support healthcare delivery across Southeast Asia, South Asia, and the Pacific region.

The broader lesson extends beyond surgery itself. Frugal innovation demonstrates that healthcare technology does not need to be expensive to be effective. By focusing on local needs, resource efficiency, and practical implementation, innovators can create solutions that deliver both clinical excellence and economic sustainability.

Conclusion

Frugal minimally invasive devices such as Gas Insufflation-Less Laparoscopic Surgery (GILLS), portable digital endoscopy platforms, and realistic procedural simulators are transforming surgical care across Asia. They reduce dependence on expensive infrastructure, expand access to underserved populations, support environmental sustainability, and strengthen local healthcare capacity.

For healthcare leaders seeking scalable solutions to improve surgical access, these innovations offer more than cost savings—they provide a blueprint for a more equitable, resilient, and sustainable future for surgical care across the region.
