Jaundice

Jaundice

Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...

Diseases of the Liver and Gallbladder

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

Cholecystitis

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Hepatic Portal System

Hepatic Portal System

The hepatic portal system, a critical part of our circulatory framework, transports nutrient-laden, deoxygenated blood from the gastrointestinal tract and spleen to the liver. This ingenious system plays an indispensable role in maintaining our body's metabolic equilibrium.
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is responsible...

Chronic Pancreatitis II: Pathophysiology

Chronic Pancreatitis II: Pathophysiology

Chronic pancreatitis is a progressive and irreversible inflammation of the pancreas, most often caused by long-term alcohol abuse, but it can also be related to ductal obstruction, smoking, or genetic factors.Chronic pancreatitis occurs when the pancreas is repeatedly exposed to harmful agents like alcohol, smoking, ductal obstruction, or genetic predisposition. These factors lead to the release of toxic metabolites and inflammatory cytokines, sustaining chronic inflammation in the pancreatic...

Chronic Pancreatitis I: Introduction

Chronic Pancreatitis I: Introduction

Chronic pancreatitis is a long-standing, relapsing inflammation of the pancreas, characterized by irreversible damage to the gland. It results in progressive destruction of the pancreatic parenchyma, fibrosis, and eventual loss of both exocrine and endocrine function. The disease may evolve gradually after multiple episodes of acute pancreatitis or develop independently.EtiologyChronic pancreatitis can arise from a variety of causes:Alcohol use is the leading cause, accounting for 70–80% of...

Summary

This summary is machine-generated.

A rare aberrant bile duct variation masked a Klatskin tumor in a patient presenting with elevated liver enzymes, not jaundice. This case highlights the diagnostic challenges posed by unusual biliary anatomy in cholangiocarcinoma detection.

Area of Science:

Hepatobiliary Surgery
Gastroenterology
Surgical Oncology

Background:

Cholangiocarcinoma (CC) is a common biliary tract malignancy, often diagnosed at advanced, unresectable stages.
Nonspecific symptoms and painless jaundice typically signal CC, delaying early diagnosis.
Extrahepatic localization is common for CC.

Observation:

A 67-year-old woman presented with persistently elevated liver function tests.
Diagnostic imaging revealed a Klatskin tumor (type II).
The patient had a complete biliary drainage via an aberrant bile duct, notably without jaundice.

Findings:

The aberrant bile duct, a rare anatomical variation (present in <5% of the population), directly drained the right posterior bile duct into the common bile duct.
This aberrant anatomy concealed significant intrahepatic cholestasis and obscured the diagnosis of the Klatskin tumor.
Surgical intervention involved a right hepatic trisegmentectomy following liver volume augmentation via preoperative vein embolization.

Implications:

Aberrant bile ducts can mask severe intrahepatic cholestasis and hinder the diagnosis of cholangiocarcinoma.
This case underscores the importance of considering rare anatomical variations in the differential diagnosis of biliary tract abnormalities.
Early recognition of such variations is crucial for timely and effective management of Klatskin tumors.
