What is foregut duplication cyst?
INTRODUCTION: Foregut duplication cysts are rare congenital malformations during neonatal period. They are frequently asymptomatic, but may cause respiratory distress due to compression of airways. They are usually found in the right posterior mediastinum in retrocardiac position.
What causes duplication cysts?
The partial or abortive twinning theory explains the occurrence of these duplication cysts is due to incomplete twinning of the alimentary tract.
How rare is a duplication cyst?
Gastric duplication cysts are a rare phenomenon and account for only 2–9% of all gastrointestinal duplications [1]. The majority is circular, non-communicating and surrounded by a smooth muscular coat. They can be found anywhere in the stomach, with the majority being located on the greater curvature.
Are duplication cysts cancerous?
Occasionally, these cysts are asymptomatic, and can be found incidentally in adulthood. Duplication cysts can rarely turn malignant, and a few such cases have been reported.
What is a foregut cyst?
Foregut cysts can be defined as closed epithelium-lined sacs developing abnormally in the thorax from the primitive developing upper gut and respiratory tract.
What are the organs of the foregut?
Foregut gives rise to the esophagus, stomach, liver, gallbladder, bile ducts, pancreas and proximal duodenum.
What causes cysts to form?
Cysts develop when the protein is trapped below the skin because of disruption to the skin or to a hair follicle. These cysts may develop for a number of reasons, but trauma to the skin is typically thought to be the main cause. When numerous, an underlying genetic disorder such as Gardner syndrome may be the cause.
What is a Tailgut duplication cyst?
Tailgut duplication cyst (retro-rectal cystic hamartoma) is a rare congenital developmental lesion arising from post-natal primitive gut remnants. Tailgut cysts are found more commonly in middle-aged females. It may be asymptomatic or symptomatic in complicated cases.
What is a GI duplication?
Gastrointestinal tract duplication cysts are rare congenital gastrointestinal malformation in young patients and adults. They consist of foregut duplication cysts, small bowel duplication cysts, and large bowel duplication cysts.
What is a duodenal cyst?
Duodenal duplication cysts constitute a rare congenital anomaly of the gastrointestinal tract. A recent meta-analysis of the literature between 1999 and 2009 reported a total of 47 cases of duodenal duplication cysts. 3. They form during the embryonic development of the human digestive organs.
What is an enteric duplication cyst?
Enteric duplication cysts (EDCs) are rare congenital malformations formed during the embryonic development of the digestive tract. They are usually detected prenatally or in the first years of life.
What is the purpose of foregut?
4.1. The foregut, or oesophagus, transfers ingesta from the mouth to the stomach or directly to the intestines of those species lacking this structure. It may also serve as a temporary site for food storage in reptiles or birds, where it is known as the crop.
What is the function of the foregut?
In adult vertebrates, the foregut is primarily for ingestion and partial digestion of food. In certain animals such as birds with crops, the foregut thus also functions for temporary storage of food.
Where is the most common site of intestinal duplication?
The most common site of duplication is the jejunum and ileum followed by the esophagus, stomach, duodenum, and colon. Intestinal duplications usually manifest in the 1st or 2nd year of life. Duplications can be asymptomatic or cause obstructive symptoms, chronic pain, gastrointestinal bleeding, or abdominal mass.
What is a duodenal duplication cyst?
What is gut signature?
The gut signature sign is an ultrasound term used to describe the appearance of the gastrointestinal wall.
