PPCS is caused by an electrocautery-induced injury to the wall of the colon that occurs during removal of colon polyps. [3] PPCS occurs when the electric current extends beyond the mucosa, entering the muscularis propria and serosa, resulting in a full thickness (transmural) burn injury. [ 1 ]
The size of the ulcers is usually 0.5–4 cm. [5] The lesion is most often located on the anterior (front) or lateral (side) rectal wall, centered on a rectal fold, [1] usually 10 cm from the anal verge. [8] Less commonly there may be ulcers in the anal canal or even in the sigmoid colon. [5]
A colorectal polyp is a polyp (fleshy growth) occurring on the lining of the colon or rectum. [1] Untreated colorectal polyps can develop into colorectal cancer. [2] Colorectal polyps are often classified by their behaviour (i.e. benign vs. malignant) or cause (e.g. as a consequence of inflammatory bowel disease).
Gardner syndrome is an autosomal dominant form of polyposis characterized by the presence of multiple polyps in the colon together with tumors outside the colon. [3] The extracolonic tumors may include osteomas of the skull, thyroid cancer , epidermoid cysts , fibromas , [ 4 ] as well as the occurrence of desmoid tumors in approximately 15% of ...
A sessile serrated lesion (SSL) is a premalignant flat (or sessile) lesion of the colon, predominantly seen in the cecum and ascending colon. SSLs are thought to lead to colorectal cancer through the (alternate) serrated pathway. [1] [2] This differs from most colorectal cancer, which arises from mutations starting with inactivation of the APC ...
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]
Colorectal surgery is a field in medicine dealing with disorders of the rectum, anus, and colon. [1] The field is also known as proctology , but this term is now used infrequently within medicine and is most often employed to identify practices relating to the anus and rectum in particular.
Fundic gland polyposis is a medical syndrome where the fundus and the body of the stomach develop many fundic gland polyps.The condition has been described both in patients with familial adenomatous polyposis (FAP) and attenuated variants (AFAP), and in patients in whom it occurs sporadically.
