What is a enteric duplication cyst?
Enteric duplication cysts are rare congenital malformations that can occur at any point along the digestive tract, most commonly the small bowel. They are characterized by the presence of an outer layer of smooth muscle and an inner lining of mucosa that may resemble any portion of the digestive tract.
What is duplication cyst mean?
Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract. They may be cystic or tubular in conformation.
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. Herein, we present the case of a patient who had a malignancy found to arise in a duodenal duplication cyst.
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.
What is duodenal duplication?
Duodenal duplication, a rare congenital malformation, can also be observed in adulthood. Although it can be cystic or tubular, communicating or non-communicating, cystic and non-communicating forms are the most common. Several complications, such as obstruction, bleeding, perforation and pancreatitis, may result.
How are mesenteric cysts treated?
The preferred treatment of mesenteric cysts is enucleation, [18, 8, 24, 5] though intestinal resection is frequently required to ensure that the remaining bowel is viable. Bowel resection may be required in 50-60% of children with mesenteric cysts, whereas resection is necessary in about one third of adults.
What is 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 are the symptoms of a mesenteric cysts?
Mesenteric cysts are often asymptomatic and discovered as an incidental finding from radiological investigations, but may present with acute or chronic abdominal pain (55%-81%), palpable mass (44%-61%), distension (17%-61%), nausea and vomiting (45%), constipation (27%) and diarrhoea (6%)[1].
What causes mesenteric cyst?
Mesenteric cysts, described by Benevenni in 1507, arise from duodenal to sigmoid mesentery. They generally cause non-specific symptoms or rarely rupture, tort and obstruct. They result from lymphatic malformation, occult trauma or infection.
What happens during duplication?
Duplication Duplication is a type of mutation that involves the production of one or more copies of a gene or region of a chromosome. Gene and chromosome duplications occur in all organisms, though they are especially prominent among plants. Gene duplication is an important mechanism by which evolution occurs.
What does duplicating efforts mean?
If you say that there has been duplication of something, you mean that someone has done a task unnecessarily because it has already been done before.
What is the definition of an intestinal duplication?
Intestinal Duplications (also called Intestinal Tract Duplications, duplication cysts, foregut duplications, esophageal duplications, others) Definition: An abnormal portion of intestine which is attached to or intrinsic with the normal bowel. The cyst or duplicated bowel is typically lined with intestinal mucosa,…
What kind of cyst is an enteric duplication cyst?
Enteric duplication cysts are elongated, tubular, or spherical cystic masses, usually unilocular and anechoic (Fig. 24.3). Multiple septations and “sludge” may be seen (Table 24.2). The location and mass effect on adjacent bowel can suggest the diagnosis.
How is the diagnosis of Enteric duplication made?
Diagnosis is made with ultrasound and/or contrast studies, which may show a filling defect. Ultrasound can be used prenatally, leading to early treatment postnatally ( Laje et al., 2010 ). CT and MRI may be used to define the location and size of the duplication.
What are the characteristics of a duplication cyst?
Duplications may vary widely in size and length. They may be spherical or tubular in appearance. The duplications must posses a well-developed layer of smooth muscle and a mucous membrane lining derived from some part of the GI tract. Exact incidence is unknown.
