Gallbladder01:17

Gallbladder

2.8K
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

Gastritis-II: Pathophysiology

1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Gastritis-I: Introduction and Types

3.1K
Gastritis, defined by the inflammation or irritation of the stomach lining or gastric mucosa, manifests in several distinct forms: acute, chronic, reactive, and a specific subtype known as autoimmune metaplastic atrophic gastritis.
Acute gastritis presents as a sudden inflammation triggered by various stressors to the stomach lining, such as exposure to corrosive agents, local irritants like aspirin and other NSAIDs, alcohol consumption, radiation therapy, physical trauma, severe burns, sepsis,...

Gastric Emptying01:16

Gastric Emptying

4.6K
Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...

Summary

A rare case of gastric heterotopia extensively involving the gallbladder was documented in a 17-year-old female. This condition was linked to peptic ulceration within the abnormal gastric tissue, a complication observed in only one prior reported instance.

Area of Science:

  • Gastroenterology
  • Pathology
  • Surgical Case Reports

Background:

  • Gastric heterotopia, the presence of gastric tissue outside the stomach, is a rare congenital anomaly.
  • While gastric heterotopia can occur in various locations, involvement of the gallbladder is exceptionally uncommon.
  • Peptic ulceration in heterotopic gastric mucosa is a known but infrequent complication.

Purpose of the Study:

  • To report a unique case of extensive gastric heterotopia involving the gallbladder in a young female.
  • To highlight the association of peptic ulceration with this rare condition.
  • To compare the extent of this case with previously documented instances of gastric heterotopia in the gallbladder.

Main Methods:

  • Case presentation of a 17-year-old female with symptomatic gastric heterotopia.

  • Review of relevant medical literature on gastric heterotopia involving the gallbladder.
  • Histopathological examination of the resected specimen.

    • Main Results:

    • The patient presented with extensive gastric heterotopia within the gallbladder.
    • Peptic ulceration was identified in the heterotopic gastric mucosa.
    • The observed extent of gastric heterotopia in this case surpassed that of previously reported cases.

    Conclusions:

    • Extensive gastric heterotopia of the gallbladder is an exceedingly rare condition.
    • The presence of peptic ulceration in heterotopic gastric mucosa, even in the gallbladder, is a significant clinical finding.
    • This case underscores the importance of considering rare pathologies in the differential diagnosis of gallbladder abnormalities.
