Clinical course of obstructive jaundice associated with operated meconium peritonitis in neonates
1Department of Pediatric Surgery, Graduate School of Medical Science, Kyoto Prefectural University of Medicine, Kyoto, Japan.
Background/Purpose:
Meconium peritonitis (MP) may induce prolonged cholestasis after laparotomy. In this study, we investigated the postoperative clinical course of MP retrospectively and discuss the relationship between MP and the development of obstructive jaundice, including biliary atresia (BA).
Patients And Methods:
Between 1979 and 2008, 23 infants with MP underwent laparotomy at our institution. Eleven of the 23 infants (47.8%) developed obstructive jaundice postoperatively. The medical charts of these 11 infants were reviewed.
Results:
The causative disease underlying MP included jejunoileal atresia in 10 and cloacal anomaly in 1. Of these 11 infants, 4 had acholic stools. Nine of the 11 improved with conservative management including an expectant approach, choleretic agents, and exchange blood transfusion. To differentiate the diagnosis from BA, open cholangiography was required in 2 cases following negative HIDA scintigraphy and a small gallbladder on ultrasonography. One of these 2 cases was diagnosed as BA and underwent hepatic portoeneterostomy simultaneously, after which the infant became jaundice free.
Conclusions:
Postoperative cholestasis after MP was a transient condition in most cases. However, ultrasonography and HIDA scintigraphy should be performed to differentiate BA in infants with MP who show prolonged jaundice with acholic stools.
Insights
Meconium peritonitis (MP) can cause prolonged jaundice in infants. Most cases resolve with conservative treatment, but imaging is crucial to rule out biliary atresia (BA) in persistent cases.
Area of Science:
- Pediatric Surgery
- Neonatal Gastroenterology
- Hepatology
Background:
- Meconium peritonitis (MP) is a rare neonatal condition that can lead to prolonged cholestasis post-laparotomy.
- Obstructive jaundice, including biliary atresia (BA), is a potential complication in infants with MP.
Purpose of the Study:
- To retrospectively analyze the clinical course of infants with MP.
- To investigate the association between MP and the development of obstructive jaundice.
- To differentiate MP-associated jaundice from biliary atresia (BA).
Main Methods:
- Retrospective review of 23 infants with MP who underwent laparotomy between 1979 and 2008.
- Analysis of clinical data for 11 infants who developed postoperative obstructive jaundice.
- Utilized ultrasonography, HIDA scintigraphy, and open cholangiography for diagnosis.
Main Results:
- Of 23 infants with MP, 11 (47.8%) developed obstructive jaundice.
- Jejunoileal atresia was the underlying cause in 10 infants; cloacal anomaly in 1.
- Nine of 11 infants improved with conservative management; 2 required further investigation for BA.
Conclusions:
- Postoperative cholestasis following meconium peritonitis is typically transient.
- Ultrasonography and HIDA scintigraphy are essential to differentiate BA in infants with MP and prolonged jaundice with acholic stools.
