Most polyps are benign and do not need to be removed. Surgical removal of the gallbladder (cholecystectomy) is recommended when a gallbladder polyp larger than 1 cm is found, even if the person has no symptoms clearly related to the polyp. Laparoscopic surgery is an option for small or solitary polyps. [citation needed]
A polyp is an abnormal growth of tissue projecting from a mucous membrane. If it is attached to the surface by a narrow elongated stalk, it is said to be pedunculated; if it is attached without a stalk, it is said to be sessile. Polyps are commonly found in the colon, stomach, nose, ear, sinus(es), urinary bladder, and uterus.
Rokitansky–Aschoff sinuses are pseudodiverticula or pockets in the wall of the gallbladder.They may be microscopic or macroscopic. Histologically, they are outpouchings of gallbladder mucosa into the gallbladder muscle layer and subserosal tissue as a result of hyperplasia and herniation of epithelial cells through the fibromuscular layer of the gallbladder wall.
The serrated polyposis syndrome (SPS) is a relatively rare condition characterized by multiple and/or large serrated polyps of the colon. Serrated polyps include SSLs, hyperplastic polyps, and traditional serrated adenomas. Diagnosis of this disease is made by the fulfillment of any of the World Health Organization's (WHO) clinical criteria. [4]
Cancer of the gallbladder may also be found incidentally after surgical removal of the gallbladder, with 1–3% of cancers identified in this way. Gallbladder polyps are mostly benign growths or lesions resembling growths that form in the gallbladder wall, [26] and are only associated with cancer when they are larger in size (>1 cm). [21]
The types of polyps found in SPS include sessile serrated adenomas/polyps, traditional serrated adenomas, and hyperplastic polyps. SPS occurs in two phenotypes: proximal and distal. Proximal SPS has a greater risk of CRC than distal SPS. The vast majority of cases may be managed with colonoscopy with removal polyps (polypectomy). Polyp removal ...
These usually begin appearing before age 20, but the term juvenile refers to the type of polyp (i.e. benign hamartoma, as opposed to adenoma for example), not to the age of the affected person. [1] While the majority of the polyps found in juvenile polyposis syndrome are non- neoplastic , hamartomatous , self-limiting and benign, there is an ...
The localized form is a single mass, typically in the fundus, that protrudes into the lumen of the gallbladder in the form of a polyp. [5] [6] The segmental form is characterized by its annular (ring-shaped) distribution of adenomyomatosis in the body of the gallbladder, often giving it an hourglass-like appearance. [5] [6]
