Colonic polypectomy is the removal of colorectal polyps in order to prevent them from turning cancerous.. Method of removing a polyp with a snare. Gastrointestinal polyps can be removed endoscopically through colonoscopy or esophagogastroduodenoscopy, or surgically if the polyp is too large to be removed endoscopically.
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 ]
Once an adenomatous polyp is identified during colonoscopy, there are several methods of removal, including using a snare or a heating device. [22] Colonoscopies are preferred over sigmoidoscopies because they allow the examination of the entire colon and can detect polyps in the upper colon, where more than half of polyps occur.

Polyps are either pedunculated (attached to the intestinal wall by a stalk) or sessile (grow directly from the wall). [5] [6]: 1342 In addition to the gross appearance categorization, they are further divided by their histologic appearance as tubular adenoma which are tubular glands, villous adenoma which are long finger like projections on the surface, and tubulovillous adenoma which has ...
A total of 15 people who underwent colonoscopy (0.13%) had major bleeding after polyp removal. None of the participants experienced a colon perforation due to colonoscopy. After 10 years, an intention-to-screen analysis showed a significant relative risk reduction of 18% in the risk of colorectal cancer (0.98% in the invited group vs. 1.20% in ...
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]
However, by 1988, an easy to use applicator delivery system was developed, and a functional reloadable endoclip system was described. [2] This consisted of a stainless steel clip (of size approximately 6 mm long and 1.2 mm wide at the prongs) with a metal deployment device (that could be used to insert the clip into the endoscopic camera, and ...
Gardner's syndrome (also known as Gardner syndrome, familial polyposis of the colon, [1] or familial colorectal polyposis [2]) is a subtype of familial adenomatous polyposis (FAP). 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 ]
