Enteric duplication cysts, sometimes simply called duplication cysts, are rare congenital malformations of the gastrointestinal tract. [1] They most frequently occur in the small intestine, particularly the ileum, but can occur anywhere along the gastrointestinal tract. [1] They may be cystic or tubular in conformation. [2]
Cystoisospora belli, previously known as Isospora belli, is a parasite that causes an intestinal disease known as cystoisosporiasis. [1] This protozoan parasite is opportunistic in immune suppressed human hosts. [2] It primarily exists in the epithelial cells of the small intestine, and develops in the cell cytoplasm. [2]
However it is not as sensitive or accurate in diagnosis as the other tests available. It is important to distinguish the E. histolytica cyst from the cysts of nonpathogenic intestinal protozoa such as Entamoeba coli by its appearance. E. histolytica cysts have a maximum of four nuclei, while the commensal Entamoeba coli cyst has up
A cyst is the environmentally stable stage of the parasite, that facilitates transmission between hosts. [8] The infection process in the host begins with the ingestion of cysts, which pass through the stomach into the first part of small intestine, or the duodenum.
Cystojejunostomy: In this procedure a connection is created between the cyst and the small intestine so that the cyst fluid directly into the small intestine. [14] Cystoduodenostomy: In this procedure a connection is created between the duodenum (the first part of the intestine) and the cyst to allow drainage of the cyst content into duodenum. [15]
The small intestine or small bowel is an organ in the gastrointestinal tract where most of the absorption of nutrients from food takes place. It lies between the stomach and large intestine, and receives bile and pancreatic juice through the pancreatic duct to aid in digestion. The small intestine is about 5.5 metres (18 feet) long and folds ...
A branchial cyst, according to the Cleveland Clinic, is a small fluid-filled sac that may look like a lump under the skin on the side of the neck. It is considered one of the most common neck mass ...
The parasite is transmitted by environmentally hardy cysts (oocysts) that, once ingested, exist in the small intestine and result in an infection of intestinal epithelial tissue. [7] Transmission by ingestion or inhalation of coughed-on fomites is a second, less likely route of infection.
