The haustra (sg.: haustrum) of the colon are the small pouches caused by sacculation (sac formation), which give the colon its segmented appearance. The teniae coli run the length of the colon. A proposed explanation for the existence of haustra is that the colon becomes sacculated between the teniae coli because the taenia coli are shorter ...
Leadpipe colon is a term used in radiology to describe a specific, characteristic appearance of the colon, typically seen on barium enema radiographs. The term is associated with a rigid, non-distensible colon that has lost its normal haustral folds, presenting a smooth, tubular, or "pipe-like" appearance. [ 1 ]
If an enterocele/sigmoidocele, or prolapse of the rectum/colon, is also present, the surgical treatment will take this concurrent condition into account while planning and performing the repairs. [2] Estrogen that is administered vaginally before surgical repair can strengthen the vaginal tissue providing a more successful outcome when mesh or ...
Site of action: colon; Onset of action: 6–10 hours; Examples: senna, bisacodyl [3] Prolonged use of stimulant laxatives can create drug dependence by damaging the colon's haustral folds, making users less able to move feces through their colon on their own. A study of patients with chronic constipation found that 28% of chronic stimulant ...
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]
The gastrocolic reflex or gastrocolic response is a physiological reflex that controls the motility, or peristalsis, of the gastrointestinal tract following a meal. It involves an increase in motility of the colon consisting primarily of giant migrating contractions, in response to stretch in the stomach following ingestion and byproducts of digestion entering the small intestine.

Traditional serrated adenoma seen under microscopy with H&E stain, showing serrated crypts. SPS may occur with one of two phenotypes: distal or proximal. [6] The distal phenotype may demonstrate numerous small polyps in the distal colon and rectum, whereas the proximal phenotype may be characterized by relatively fewer, but larger polyps in the proximal colon (cecum, ascending colon, etc.). [6]
The signs and symptoms of colorectal cancer depend on the location of the tumor in the bowel, and whether it has spread elsewhere in the body ().The classic warning signs include: worsening constipation, blood in the stool, decrease in stool caliber (thickness), loss of appetite, loss of weight, and nausea or vomiting in someone over 50 years old.
