Key Takeaways
- Sawong Kevin and his brother Tom were conjoined twins born in Papua New Guinea, sharing a liver, parts of the gastrointestinal tract, and major blood vessels.
- Tom had a severe congenital heart defect, only one kidney, and underdeveloped lungs, making his survival impossible without Sawong’s support.
- A multidisciplinary team from Sydney Children’s Hospital, Westmead, traveled to Port Moresby, assessed the twins, and arranged an urgent air‑lift to Australia for separation surgery.
- The eight‑hour operation revealed additional shared vessels; Tom died immediately after separation, while Sawong emerged stable and is now thriving.
- The family hopes the case will spotlight the need for improved neonatal and surgical services in Papua New Guinea, where infant mortality remains far higher than in Australia.
Background of the Conjoined Twins
Sawong Kevin and his brother Tom were born in October in a remote area of Papua New Guinea, joined at the chest, abdomen, and pelvis. Their mother, Fetima Tinggar, described the twins as a source of joy despite the extraordinary medical challenge they presented. The boys were immediately recognized as a rare case of thoraco‑omphalopagus conjoined twins, a condition that occurs roughly once every decade in a surgeon’s career. Their shared anatomy meant that any attempt to keep them together would inevitably lead to fatal complications for both infants.
Medical Challenges and Shared Anatomy
Imaging and clinical examination revealed that the twins shared a liver, portions of their gastrointestinal tract, and several major blood vessels. Tom’s upper body appeared cyanotic while the lower half was pink, a puzzling sign that reflected his compromised circulation. He also suffered from a congenital heart defect, possessed only one kidney, and had markedly underdeveloped lungs, forcing Sawong to perform the work of two bodies—Sawong’s heart beat rapidly, he breathed fast, and he appeared constantly hungry as he supplied oxygen and nutrients for both. These findings indicated that Tom’s anomalies were incompatible with independent life.
Decision to Separate and Prognosis
After days of careful evaluation, Dr. Gordon Thomas and his team concluded that separation was the only viable option, despite the high risk. They explained to the parents that if the twins remained united, both would die; if separated, Sawong had a realistic chance of survival while Tom’s prognosis was grim. The parents, though devastated by the prospect of losing one son, consented to the transfer to Sydney, trusting that the medical team could give Sawong the best opportunity to thrive.
International Response and Planning
The rarity of the case attracted attention from hospitals and governments in Germany, India, and Australia. A specialist team from Children’s Hospital, Westmead—including pediatric transplant surgeon Dr. Thomas and neonatologist/retrieval specialist Tracey Lutz—was invited to Port Moresby to assess the twins. Working with limited local equipment, they performed scans, drew detailed diagrams, and built a comprehensive surgical plan, anticipating unexpected findings during the operation.
Transport to Sydney
A LifeFlight aircraft retrieved the twins from Port Moresby for the urgent transfer to Sydney. The flight lasted over five hours, during which the crew had to monitor both infants continuously, adjusting cabin pressure to avoid exacerbating Tom’s breathing difficulties. Specialized neonatal equipment was used to stabilize the twins en route, and the medical team remained prepared for any sudden deterioration in either child’s condition.
Pre‑operative Assessment in Hospital
Upon arrival at Children’s Hospital, Westmead, the team discovered that the twins’ condition was more critical than anticipated, necessitating an immediate separation. The surgeons reviewed the shared vasculature, noting that the anatomy was even more complex than initially visualized, with additional major blood vessels and intricate hepatic connections. Contingency plans were made for unforeseen structures that might be encountered once the incision began.
The Separation Surgery
The marathon operation lasted eight hours and involved five specialist surgeons, a large team of anesthetists, surgical nurses, and support staff. As the surgeons proceeded, they discovered that the twins shared more major blood vessels than originally identified, and the liver anatomy presented unique challenges. Despite these surprises, the team meticulously divided the shared organs, ensuring adequate blood flow to Sawong while attempting to preserve as much function as possible for Tom.
Immediate Outcome and Loss of Tom
Tom succumbed almost instantly after the separation, his tiny lungs and congenital heart defect unable to sustain life without Sawong’s support. Fetima Tinggar described the loss as an open wound, expressing profound grief but also acknowledging that Tom’s sacrifice allowed Sawong to survive. The medical team, while saddened by the outcome, recognized that the separation had given Sawong a chance at life that would not have existed otherwise.
Sawong’s Recovery and Hospital Life
In the days following surgery, Sawong showed remarkable resilience. He began to feed well, his heart rate stabilized, and his breathing became regular. Hospital staff noted his wide eyes and charismatic smile, describing him as a “superstar” who brightened the wards. Dr. Thomas remarked that Sawong was doing far better than expected, and that his recovery represented the ultimate reward for the team’s effort.
Family Perspective and Future Plans
Fetima and Kevin Mitiam remain focused on Sawong’s ongoing care, expressing hope that he will continue to thrive. They plan to return to Papua New Guinea in the coming weeks, confident that Sawong’s condition can be managed locally with appropriate follow‑up. The family emphasized that they will always feel a debt of gratitude to the Sydney medical team and that a place for Sawong will remain at Children’s Hospital should he ever need further specialized intervention.
Broader Implications for Papua New Guinea Health Care
The case underscores the stark disparities in medical resources between Papua New Guinea and affluent nations like Australia. With an infant mortality rate roughly ten times higher than Australia’s, PNG’s public health system struggles to provide even basic neonatal care, let alone complex surgical separations. Dr. Glen Mola, a leading obstetrician in Port Moresby, recently urged families to postpone pregnancies due to overrun maternity wards, highlighting the urgent need for investment in maternal and child health services. The family’s wish is that their sons’ story will inspire improvements, ensuring that future children receive timely, life‑saving care closer to home.
