What does a fold in the colon mean?

Description. The haustra of the colon are the small pouches caused by sacculation, which give the colon its segmented appearance. The semilunar folds of the colon are produced by the contractions of the colon, visible as crescent-shaped folds between the haustra. Text by Antoine Micheau, MD - Copyright IMAIOS.

What mucosal folds are present in colon?

The mucosa of the colon is devoid of villi that characterize the small intestine but contains crypts of Lieberkühn (which are larger than those found in the ileum) and crescentic folds (plicae circulares) that correspond to the external sacculations termed haustra.

What causes a fold in the stomach?

Enlarged or giant gastric folds are due to diffuse mucosal hypertrophy, which may be due to a hyperplastic or nonhyperplastic gastropathy. Hyperplastic gastropathy – The gastric epithelial cells that compose the oxyntic glands become hyperplastic and give rise to giant mucosal folds.

What causes folds in esophagus?

The folds probably represent areas of heaped-up or crinkled mucosa, due to simultaneous longitudinal scarring from reflux esophagitis. Between 10 to 20% of patients with reflux esophagitis develop peptic strictures as a result of circumferential scarring of the distal esophagus.

Does the large intestine have folds?

The mucosa of the large intestine does not have folds comparable to the plicae circularis, except in the rectum. Also, the intestinal villi are absent beyond the ileocecal valve. The mucosa of the colon is lined by a simple columnar epithelium with a thin brush border and numerous goblet cells.

What is normal mucosa in colon?

Normal Appearance

Normal colonic mucosa is pale pink, smooth, and glistening, and submucosal blood vessels are commonly seen throughout the colon (see Figures 6-6, A; 6-11; 6-12; and 6-13, A-B).

Is esophageal stricture life threatening?

Many patients need more than one dilation over time to keep the esophagus wide enough for food to pass through. In rare cases, severe and untreated esophageal strictures can cause perforations (small rips), which can be life-threatening.

What is the function of haustra?

Haustra are saccules in the colon that give it its segmented appearance. Haustral contraction is activated by the presence of chyme and serves to move food slowly to the next haustra, along with mixing the chyme to help with water absorption.

Can you feel pain in your colon?

The colon is another name for the large intestine. It is an important part of the digestive system. Sometimes, a person can experience pain in this area. Inflammation, irritation, and obstruction in the colon can all cause pain, which a person will typically feel as abdominal pain.
