Cholecystitis01:20

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...

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 Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

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...
Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Area of Science:

  • Hepatology
  • Gastroenterology
  • Oncology

Background:

  • Primary sclerosing cholangitis (PSC) is associated with a 10% risk of developing cholangiocarcinoma.
  • Currently, no specific risk factors, imaging, or serum markers reliably identify early cholangiocarcinoma in PSC patients.

Purpose of the Study:

  • To review the current understanding and diagnostic approaches for malignancies in patients with primary sclerosing cholangitis.
  • To highlight the importance of early detection and management strategies for associated cancers.

Main Methods:

  • Review of existing literature and clinical guidelines regarding PSC and associated malignancies.
  • Discussion of diagnostic tools, including endoscopic retrograde cholangiography (ERC) with brush cytology.
  • Consideration of treatment modalities like liver transplantation and surgical interventions.

Main Results:

  • Cholangiocarcinoma complicates PSC in approximately 10% of cases, with limited early diagnostic tools available.
  • Endoscopic retrograde cholangiography with brush cytology is recommended for suspected cholangiocarcinoma.
  • Gallbladder polyps in PSC patients are frequently malignant, warranting a liberal approach to cholecystectomy.
  • Hepatocellular carcinoma occurs in 2%-4% of end-stage liver disease patients.
  • Inflammatory bowel disease patients with PSC are at increased risk for colorectal neoplasia, necessitating surveillance colonoscopies.

Conclusions:

  • Early diagnosis of cholangiocarcinoma in PSC remains challenging, emphasizing the need for improved biomarkers.
  • Epigenetic markers show promise as potential biomarkers for early malignancy detection in PSC.
  • Proactive surveillance and timely intervention, including cholecystectomy and consideration for transplantation, are crucial for managing PSC-associated cancers.
