An anal/rectal abscess is a pus-filled lump around the anus (the opening of the rectum to the outside of the body) or the rectum (the portion of the gastrointestinal tract that begins at the end of the colon and ends at the anus).
The sigmoid colon is the part of the large intestine that is closest to the rectum and anus. When the sigmoid colon is longer than usual and coils onto itself, it is known as a redundant sigmoid colon.
Superior mesenteric artery (SMA) syndrome describes a rare condition when the duodenum (the part of the small intestine that connects to the stomach) is compressed between two arteries (blood vessels that carry blood away from the heart) – the aorta (main artery of the body) and the superior mesenteric artery (which branches off of the aorta).
Thickened gastric folds (TGF) are a common finding on radiological imaging. TGF can be a manifestation of various diseases, with possible causes ranging from inflammatory to malignant conditions.
The common bile duct is a tube that carries bile (fluid that helps with fat digestion) from the liver and gallbladder through the pancreas. Biliary stricture, also known as bile duct stricture, occurs when the bile duct gets smaller or narrower. A narrow bile duct makes it difficult for bile to pass from the liver to the small bowel which can lead to difficulty in digesting food, especially fats.
Rectal duplication cysts are rare, congenital (present from birth) malformations of the gastrointestinal tract.
