What procedure is performed for infants presenting with jaundice beyond 14 days of age?

The procedure indicated for infants presenting with jaundice beyond 14 days of age is the Kasai procedure. This surgical intervention is primarily aimed at addressing biliary atresia, a condition in which the bile ducts are absent or damaged, leading to obstructive jaundice due to the accumulation of bile. The Kasai procedure involves creating a direct connection between the liver and the small intestine (jejunum) to allow bile to drain properly and alleviate the symptoms of jaundice.

Infants diagnosed with jaundice after 14 days require careful evaluation for underlying conditions, with biliary atresia being a leading cause. The timely execution of the Kasai procedure can improve liver function and decrease the risk of subsequent complications, such as liver failure or the need for a liver transplant.

In contrast, other procedures listed are not suitable for this particular situation; for example, percutaneous biliary drainage is more appropriate for adults with obstructive jaundice rather than infants with congenital conditions. Laparoscopic cholecystectomy is typically performed for gallbladder pathology but does not address the underlying issue of biliary atresia. Lastly, hepaticojejunostomy is usually reserved for conditions related to bile duct injury or resection rather than as a first-line
