Chronic Pancreatitis II: Collaborative Care01:29

Chronic Pancreatitis II: Collaborative Care

The management of chronic pancreatitis is multifaceted, involving a comprehensive approach that includes thorough assessment, diagnostic testing, and a variety of management strategies.

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...
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...
Endoscopic Procedures V: ERCP01:26

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Chronic Pancreatitis II: Pathophysiology01:21

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: Introduction01:25

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

Primary sclerosing cholangitis (PSC) involves bile duct destruction, potentially leading to liver failure. Endoscopic therapy for dominant strictures in PSC may improve patient outcomes and survival.

Area of Science:

  • Hepatology
  • Gastroenterology
  • Radiology

Background:

  • Primary sclerosing cholangitis (PSC) causes progressive bile duct destruction, leading to end-stage liver disease.
  • Diagnosis relies on cholangiography showing multifocal strictures and dilation; magnetic resonance cholangiography is accurate but limited in early stages.
  • Dominant strictures develop in up to 60% of PSC patients, complicating diagnosis and distinguishing from cholangiocarcinoma.

Purpose of the Study:

  • To review the diagnosis and management of dominant strictures in primary sclerosing cholangitis.
  • To evaluate the role of endoscopic therapy in symptomatic patients with dominant strictures.

Main Methods:

  • Review of cholangiographic findings in PSC patients.
  • Analysis of clinical presentations, including jaundice, pruritus, and cholangitis.
  • Assessment of endoscopic retrograde cholangiography (ERC) and magnetic resonance cholangiography accuracy.
  • Evaluation of outcomes following endoscopic dilation and stenting for dominant strictures.

Main Results:

  • Dominant strictures are common in PSC, occurring in up to 60% of patients, and can be present even in asymptomatic individuals.
  • Distinguishing PSC from cholangiocarcinoma remains challenging despite combined diagnostic modalities.
  • Endoscopic dilation with or without stenting has shown clinical and radiographic improvement in patients with symptomatic dominant strictures.

Conclusions:

  • Dominant strictures are a significant complication of PSC requiring careful evaluation.
  • Endoscopic therapy is a viable option for managing symptomatic dominant strictures in PSC.
  • Evidence suggests endoscopic therapy may improve survival in PSC patients with dominant strictures.
