Inflammatory Bowel Disease V: Surgical Management

246
Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
Here are some common surgical interventions for IBD:

Histology of the Large Intestine01:26

Histology of the Large Intestine

1.9K
The large intestine, a vital component of the gastrointestinal tract, is structured with four main layers: the mucosa, submucosa, muscularis, and serosa. Each layer performs a distinct role in facilitating the smooth functioning of the large intestine.
The innermost mucosa layer comprises simple columnar epithelium, lamina propria, and muscularis mucosae. This layer is primarily populated with absorptive cells, tasked with water absorption, and goblet cells, responsible for secreting mucus to...

Histology of the Small Intestine

2.0K
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...

Histology of the Gastrointestinal (GI) Tract01:20

Histology of the Gastrointestinal (GI) Tract

1.9K
The GI tract, from beginning to end, is made up of four continuous tissue layers that adjust their structure according to their specific roles. These layers, from innermost to outermost, are known as the mucosa, submucosa, muscularis, and serosa, which are continuous with the mesentery.
The mucosa is sometimes called a mucous membrane due to its mucus-secreting features. This membrane is composed of epithelium, which directly interacts with ingested substances, and the lamina propria, a layer...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

565
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...

Stomach Histology01:26

Stomach Histology

1.9K
The stomach comprises several layers that work together to facilitate digestion and protect the organ. The outermost layer is called the serosa, which provides support and protection to the stomach. The muscularis externa layer is responsible for the mechanical breakdown of food by contracting and moving the stomach. The submucosa layer, located beneath the muscularis externa, contains connective tissue, blood vessels, nerves, and glands that secrete mucus and other substances essential for...

Area of Science:

  • Gastroenterology
  • Pediatric Surgery
  • Developmental Biology

Background:

  • Congenital pouch colon (CPC) is a rare congenital anomaly, frequently associated with anorectal malformations.
  • Diagnosis is typically made in neonates, and early intervention is crucial to prevent complications.
  • Limited research exists on the detailed histopathological characteristics of CPC.

Purpose of the Study:

  • To present the histopathological features of congenital pouch colon in two cases with diverse associated anomalies.
  • To investigate the immunohistochemical findings, including calretinin and c-Kit staining.
  • To describe unique histological findings such as cystitis glandularis, intestinal metaplasia, and an additional muscle layer.

Main Methods:

  • Case report analysis of two neonates diagnosed with congenital pouch colon.
  • Histopathological examination of surgical specimens.
  • Immunohistochemical staining using calretinin and c-Kit antibodies.

Main Results:

  • Both cases exhibited a paucity of ganglion cells and intrinsic nerve fibers, with occasional punctate positivity for calretinin.
  • Immunohistochemistry for c-Kit revealed a reduced number of interstitial cells of Cajal.
  • Case 1 showed cystitis glandularis with intestinal metaplasia, while Case 2 presented with an additional muscle layer.

Conclusions:

  • The identified novel histopathological features provide further characterization of congenital pouch colon.
  • These findings may offer insights into the pathogenesis of the pouch and its associated clinical manifestations.
  • Further research into these histological details could enhance understanding and management of CPC.
