Successful separation of xiphoomphalopagus twins
Summary
This case study details the successful separation of xiphoomphalopagus twins, conjoined from the xiphoid process to the umbilicus, including a shared liver and independent digestive tracts. Both infants survived and are thriving post-surgery.
Area of Science:
- Pediatric Surgery
- Congenital Anomalies
- Twin Studies
Background:
- Xiphoomphalopagus conjoined twins present unique surgical challenges due to shared anatomy.
- Early diagnosis and intervention are crucial for improving outcomes in conjoined twins.
Observation:
- A pair of female xiphoomphalopagus twins, delivered at 35 weeks gestation, were conjoined from the xiphoid process to the umbilicus.
- Infant A had a ventricular septal defect (VSD); both shared a fused liver but had independent biliary and alimentary systems.
- Radiological imaging confirmed fused liver and separate digestive tracts.
Findings:
- Surgical separation at 1.5 months revealed fused xiphoid processes, costal cartilages, and a single, merged liver.
- The liver was divided using electrocautery, and abdominal wall closure required relaxation incisions.
- Post-operative complications included wound dehiscence and infection, managed with full-thickness dead-foetus homografts.
Implications:
- This case highlights the feasibility of surgical separation for complex xiphoomphalopagus twins with significant organ fusion.
- Successful management of post-operative complications, including wound healing with homografts, is critical for survival.
- Long-term survival and well-being of separated conjoined twins are achievable with comprehensive surgical and medical care.
