obstructive Jaundice

Obstructive jaundice, also called surgical jaundice, occurs when mechanical blockage prevents bile flow from the liver to the duodenum, with gallstones accounting for approximately 90% of extrahepatic causes and pancreatic head carcinoma being the most important malignant etiology. The clinical distinction between benign and malignant obstruction is critical, as Courvoisier's law reminds us that painless jaundice with a palpable non-tender gallbladder suggests malignant distal biliary obstruction rather than stones, while the presence of Charcot's triad or Reynolds' pentad indicates cholangitis requiring urgent intervention. Medical students must recognize that prompt diagnosis through cholestatic liver function patterns and appropriate imaging followed by timely management, whether ERCP for stones or surgical staging for malignancy, directly impacts patient outcomes and prevents life-threatening complications such as ascending cholangitis and sepsis.
