Biliary obstruction with pruritus

Biliary obstruction with pruritus refers to severe cutaneous itching that arises as a clinical complication of impaired or blocked bile flow within the hepatobiliary system It affects pediatric and adult populations experiencing mechanical or inflammatory blockage of intrahepatic or extrahepatic bile ducts, commonly stemming from choledocholithiasis, strictures, or biliary and pancreatic neoplasms Pathophysiologically, the restriction of normal bile drainage causes systemic cholestasis and the r...

It affects pediatric and adult populations experiencing mechanical or inflammatory blockage of intrahepatic or extrahepatic bile ducts, commonly stemming from choledocholithiasis, strictures, or biliary and pancreatic neoplasms

It affects pediatric and adult populations experiencing mechanical or inflammatory blockage of intrahepatic or extrahepatic bile ducts, commonly stemming from choledocholithiasis, strictures, or biliary and pancreatic neoplasms These accumulating substances stimulate peripheral sensory neurons and central neurohumoral pathways, manifesting clinically as persistent, often intractable itching characteristically prominent on the palms and soles without primary cutaneous lesions

Pathophysiologically, the restriction of normal bile drainage causes systemic cholestasis and the retrograde accumulation of pruritogenic substances—such as bile acids, lysophosphatidic acid, and endogenous opioids—in the circulation and tissues These accumulating substances stimulate peripheral sensory neurons and central neurohumoral pathways, manifesting clinically as persistent, often intractable itching characteristically prominent on the palms and soles without primary cutaneous lesions
