Cholestasis means reduced or stopped bile flow. It is a clinical concept used to describe a pattern of disease affecting bile formation or bile drainage. It is commonly used in hepatology and gastroenterology when interpreting liver tests and jaundice. It can reflect problems inside the liver or blockage in the bile ducts outside the liver.

Biliary Colic is a clinical term for episodic pain that typically comes from transient blockage of bile flow from the gallbladder. It is most often discussed in the setting of gallstones (cholelithiasis) and right upper quadrant abdominal pain. Clinicians use it as a symptom pattern to guide evaluation, imaging choices, and risk assessment. It is common in emergency, primary care, and gastroenterology/hepatobiliary surgery discussions.

Gallbladder Sludge is a mixture of tiny particles that collect in bile inside the gallbladder. It is most often seen as a finding on right upper quadrant ultrasound imaging. It can be an incidental (unexpected) discovery or a clue in evaluating biliary pain or pancreatitis. In clinical practice, it is discussed as part of hepatobiliary (liver and bile duct) assessment.

Necrotizing Pancreatitis is a severe form of acute pancreatitis in which part of the pancreas and/or surrounding tissue loses blood supply and dies (necrosis). It is most often discussed in hospital-based gastroenterology, critical care, radiology, and GI surgery settings. The term is used to describe a specific complication pattern that can change monitoring, imaging, and intervention planning. It is primarily a clinical and radiologic diagnosis, not a single test or procedure.

Pancreatic Necrosis means death of pancreatic tissue or nearby fat due to severe inflammation. It is most often discussed as a complication of acute pancreatitis. Clinicians use the term to describe a specific pattern seen on imaging and clinical course. It matters because necrotic (dead) tissue can drive organ dysfunction and may become infected.

Intraductal papillary mucinous neoplasm (IPMN) is a type of pancreatic cystic tumor that arises from the pancreatic ducts. It produces mucin (a thick, mucus-like substance) and can dilate the pancreatic ductal system. IPMN is commonly discussed in gastroenterology, pancreatic surgery, radiology, and pathology. It matters because some IPMN lesions can progress to invasive pancreatic cancer over time.

A Pancreatic Cyst is a fluid-filled sac within or on the pancreas. It is often found on abdominal imaging done for other reasons. Some pancreatic cysts are benign, while others have malignant potential. The term is commonly used in gastroenterology, radiology, and pancreatic surgery.

A Hyperplastic Gastric Polyp is a common, usually benign growth that forms on the lining of the stomach. It develops from “reactive” (repair-type) changes in the stomach’s mucosa, often in the setting of chronic inflammation. Clinicians most often identify it during upper endoscopy performed for symptoms or anemia workups. It matters because it can bleed, coexist with other gastric conditions, or rarely contain precancerous change.

A Fundic Gland Polyp is a small growth that arises from the acid-secreting gland lining of the stomach. It is most often found in the gastric fundus and body during upper endoscopy. Many are discovered incidentally when endoscopy is performed for common upper gastrointestinal symptoms.

Gastric Polyps are raised lesions that project from the lining of the stomach. They are usually found during upper endoscopy performed for symptoms or screening. Most are benign, but some have dysplasia (precancer) or cancer risk depending on type. Clinicians use biopsy and histology (microscopic diagnosis) to classify them.
