Introduction
Common causes of gallbladder problems in newborns include congenital developmental abnormalities, biliary obstruction, infections, metabolic disorders, and bile stasis, most of which are associated with congenital factors or early bodily abnormalities. If a newborn exhibits persistent jaundice, abdominal distension, or vomiting, prompt medical evaluation is recommended. Congenital abnormalities in gallbladder shape or structure may be present.

1. Congenital developmental abnormalities:先天性发育异常: Structural or morphological anomalies of the gallbladder present at birth—such as absence of the gallbladder, an abnormally small gallbladder, or gallbladder wall thickening—can impair bile storage and excretion, representing a major congenital cause of neonatal gallbladder issues.
2. Biliary obstruction: Conditions such as biliary atresia or bile duct stenosis obstruct bile outflow, leading to bile accumulation within the gallbladder, which may result in gallbladder dilation or inflammation. This constitutes an urgent gallbladder-related condition requiring prompt intervention in newborns.
3. Infection factors: Intrauterine or postnatal bacterial or viral infections—such as cytomegalovirus or Escherichia coli—can invade the gallbladder or biliary system, causing cholecystitis, often accompanied by systemic signs of infection.
4. Metabolic disease effects: Inherited metabolic disorders, such as cystic fibrosis or glycogen storage diseases, can alter bile production or composition, indirectly leading to gallbladder dysfunction, typically accompanied by symptoms affecting other organ systems.
5. Bile stasis: Due to immature liver function in newborns, inappropriate feeding, or abnormal enterohepatic circulation, bile may accumulate in the gallbladder, resulting in abnormal gallbladder filling. This condition may gradually improve with development.
Treatment must be tailored according to the underlying cause; obstructive conditions may require surgical intervention, while infectious causes necessitate anti-infective therapy. Care should include appropriate feeding practices to avoid under- or over-feeding, monitoring for changes in jaundice, maintaining abdominal warmth, and supporting recovery of gallbladder function.
