3D visualization and 3D printing in abnormal gastrointestinal system manifestations of situs ambiguus

摘要

Situs ambiguus is a rare congenital condition whereby sufferers have abnormally positioned viscera ( , ). In such cases, it is dangerous to perform traditional diagnostic examinations, such as colonoscopy, thus anatomy is explored through invasive surgeries instead. By reconstructing a patient’s viscera three-dimensionally, it is possible to trace the physical origins of the patient’s symptoms, while eliminating the necessity for invasive surgery. We present a case of situs ambiguus with use of a combination of different approaches including 3D visualizations and patient-specific 3D printing technique to assist clinical diagnosis and patient management. This case highlights the potential value of utilising the latest visualization tools in the diagnostic assessment of complicated pathologies.
