Impact factors in biliary atresia
'Looking at the problem of biliary atresia from the vantage point of 30 years' experience with the lesion, we can say with certainty that the jaundiced baby who has had no extrahepatic bile duct has been the most disappointing patient for the surgeon in the whole realm of lesions theoretically correctable by a surgical procedure.'1
After early descriptions in the 18th and 19th centuries, surgical results were first reported in the early 20th century, and prior to the 1950s, survival of infants with biliary atresia was rare, the natural sequence being the development of cirrhosis with death from intractable liver failure.
In the 1960s, an undercredited physicist from Harvard, Thomas Kuhn, wrote his book The Structure of Scientific Revolutions wherein he introduces the world to 'paradigms' and 'paradigm shifts'. Two physicians have revolutionised the management and long-term survival of infants with biliary atresia, these being Morio Kasai and Thomas Starzl. Their interventions, the Kasai portoenterostomy and liver transplantation, respectively, represent 'paradigm shifts' in the management of biliary atresia, converting a uniformly fatal condition to one with a survival rate in excess of 80%.
Prior to Kuhn's 1962 book, science was considered a 'rational endeavour in which knowledge is achieved through painstaking, day-to-day accumulation of data, facts, and minor discoveries'. Kuhn referred to this traditional approach as 'normal science'. By comparison with Kasai and Starzl, and without minimising their exemplary contributions, perhaps the work of other researchers on the pathophysiology, advances in surgical technique, choleretics, steroids and antibiotics, are just 'normal science'?
Whatever one feels about people's respective contributions to this spectrum of progress, this special supplement of the South
African Medical Journal210 will hopefully provide useful insights into this enigmatic disease - from presentation, investigation and confirmation of diagnosis; through operative technique and perioperative care; and when this 'fails', empowering you as the clinician to care for your patient, hopefully bridging them to liver transplantation and ongoing survival.
