Diagnostic laparoscopy in prolonged jaundice.

BACKGROUND

The early diagnosis of surgical jaundice in a neonate is an important step for the surgical success in extrahepatic biliary atresia. Diagnostic laparoscopy, as in many areas in surgery, is included in the conventional diagnostic methods of extrahepatic biliary atresia.

METHODS

Since 1992, 24 infants with prolonged jaundice, in whom extrahepatic biliary atresia and neonatal hepatitis could not be differentiated with conventional diagnostic interventions, have been evaluated laparoscopically.

RESULTS

A coarse, irregular, greenish-brown liver with some degree of fine angiomatous development and an atretic gallbladder are the findings of laparoscopic evaluation in an infant with extrahepatic biliary atresia. However, in neonatal hepatitis, the liver is smooth, sharp-edged, and chocolate brown in color, and simultaneously performed cholangiography should show the passage of the contrast material both into the proximal biliary tracts and the intestinal system. In this series, 10 of 24 cases were proved to be neonatal hepatitis diagnosed by laparoscopy, so unnecessary laparotomy was avoided in 42% of the cases.

CONCLUSION

When the diagnostic laparoscopy, in which the liver and the gallbladder are directly visualized, is combined with the cholangiographic examination, the most accurate and earlier diagnosis in an infant with prolonged jaundice can be achieved, and the important period of time for the surgical success in extrahepatic biliary atresia will be minimally wasted.
