Abstract

Insights

Biliary microlithiasis, often presenting as calcium bilirubinate granules, is common in acute pancreatitis of suspected biliary origin. Early endoscopic sphincterotomy may prevent recurrent pancreatitis episodes.

Area of Science:

  • Gastroenterology
  • Hepatology
  • Endoscopic Procedures

Background:

  • Biliary microlithiasis diagnosis in acute pancreatitis often occurs weeks to months post-episode.
  • This study investigated microlithiasis during the acute phase via urgent ERCP.

Purpose of the Study:

  • To determine the prevalence of biliary microlithiasis in acute pancreatitis of suspected biliary origin during the acute phase.
  • To assess the efficacy of endoscopic sphincterotomy in preventing recurrent pancreatitis.

Main Methods:

  • Fifteen patients with acute pancreatitis of suspected biliary origin were analyzed.
  • Exclusion criteria included presence of gallstones and confirmed non-biliary etiology.
  • Bile analysis for microlithiasis was performed via urgent ERCP within 24 hours of admission.

Main Results:

  • Microlithiasis was detected in 80% of patients, primarily as calcium bilirubinate granules.
  • Three patients died from organ failure post-sphincterotomy.
  • Among the remaining 12 patients, 2 developed gallbladder stones and 1 had cholecystitis during a 30-month follow-up.
  • No recurrent pancreatitis episodes were observed during follow-up.

Conclusions:

  • Biliary microlithiasis is highly prevalent in the acute phase of pancreatitis of suspected biliary origin.
  • Endoscopic sphincterotomy demonstrated a protective effect against recurrent acute pancreatitis episodes.

Acute Pancreatitis II: Clinical Manifestations and Management

Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

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...
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 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...
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...
Acute Pancreatitis I: Introduction01:25

Acute Pancreatitis I: Introduction

Acute pancreatitis is the sudden inflammation of the pancreas caused by the early activation of digestive enzymes, leading to the autodigestion of pancreatic tissue. This results in local inflammation and, in severe cases, systemic complications.EtiologyUnderstanding the underlying causes is crucial, as identifying the etiology guides treatment and anticipates complications. Acute pancreatitis can be triggered by various factors, typically grouped into the following clinical categories.Biliary...
