Inflammatory Bowel Disease I: Ulcerative Colitis01:27

Inflammatory Bowel Disease I: Ulcerative Colitis

1.3K
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Liver Histology01:27

Liver Histology

5.3K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Histology of the Small Intestine

4.4K
The small intestine exhibits a unique histological structure that significantly enhances its function in digestion and nutrient absorption. These structures include circular folds, villi, and various specialized cells that collectively facilitate the digestion of food.
The intestinal lining features transverse folds called circular folds, each housing fingerlike projections known as intestinal villi. These villi are covered by a layer of simple columnar epithelium, also referred to as...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

867
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...

Inflammatory Bowel Disease II: Crohn's Disease

1.4K
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Chronic Pancreatitis I: Introduction01:24

Chronic Pancreatitis I: Introduction

830
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:

  • Gastroenterology and Hepatology
  • Surgical Pathology

Background:

  • Ulcerative colitis (UC) is a chronic inflammatory bowel disease.
  • Liver involvement is a known extraintestinal manifestation of UC.
  • The spectrum and severity of hepatic histological changes in UC patients undergoing surgery require further elucidation.

Purpose of the Study:

  • To assess the prevalence and nature of liver histological changes in patients with ulcerative colitis undergoing radical excisional surgery.
  • To determine the association between the severity of liver damage and the activity of colitis.
  • To evaluate the impact of liver damage on post-operative prognosis.

Main Methods:

  • Operative liver biopsies were obtained from 58 consecutive patients undergoing surgery for ulcerative colitis.
  • Histopathological examination of liver tissue was performed to identify specific changes.
  • Correlation analysis was conducted between histological findings, colitis severity, and post-operative outcomes.

Main Results:

  • Increased portal tract cellularity (83%) and fatty infiltration (83%) were the most common findings.
  • Focal necrosis was observed in 47% of patients, and early cirrhosis in 2%.
  • Severe liver damage was significantly associated with severe active colitis and poorer post-operative prognosis.

Conclusions:

  • Liver biopsy in ulcerative colitis patients undergoing surgery frequently reveals significant histological abnormalities.
  • The extent of liver damage correlates with colitis severity and impacts surgical outcomes.
  • Understanding these hepatic changes is crucial for managing ulcerative colitis patients and predicting post-operative recovery.
