Adenomas of the major duodenal papilla, also known as ampullary adenomas, can occur sporadically or in the context of genetic syndromes such as familial adenoma-tous polyposis (FAP).

2023年1月26日 · A duodenal adenoma is a non-cancerous type of polyp that starts in a part of the small intestine called the duodenum. It is considered a precancerous condition because it can turn into a type of cancer called adenocarcinoma over time.

2019年3月28日 · Duodenal adenomas (DAs) are the most frequently encountered polyps of the duodenum, at times associated with genetic syndromes and predominantly classified according to their location as non-ampullary or ampulllary.

2017年2月28日 · In this article, all practical points on how best to perform duodenal adenoma resection and data on follow-up are reviewed. Duodenal adenomas are often incidentally detected during routine upper endoscopies, yet data regarding effective management are scarce.

FA-K Duodenal polyps can originate from the mucosa (eg, adenomas) or the submucosa (eg, carcinoids); or, duodenal polyps can be hamartomas (eg, Brunner gland hyperplasia; Figures 1A, 2A, and 3A). Rarely, metastatic disease from breast, lung, or renal cancer can be seen in the duodenum as a polyp.

2024年11月15日 · Nonampullary duodenal adenomas associated with familial adenomatous polyposis should be considered for endoscopic resection based on size (≥1 cm), morphologic characteristics, advanced histology (ie, high-grade dysplasia), …

2024年3月22日 · Duodenal polyps can be categorized into various types, including hyperplastic polyps, adenomas, hamartomas, lymphoid polyps, and neuroendocrine tumors. Understanding these different types is crucial for proper diagnosis and treatment.

1 ESGE recommends that all duodenal adenomas should be considered for endoscopic resection as progression to invasive carcinoma is highly likely. Strong recommendation, low quality evidence. 2 ESGE recommends performance of a colonoscopy, if that has not yet been done, in cases of duodenal adenoma. Strong recommendation, low quality evidence.

2024年8月1日 · A nonampullary duodenal adenoma is a non-cancerous polyp that starts in the duodenum of the small intestine. It is considered a precancerous condition because it can turn into a type of cancer called adenocarcinoma over time.

Ampullary and non ampullary polyps of the duodenum are diagnosed within and outside genetic syndromes. Adenomas are the most common encountered lesions although hyperplastic polyps and other mucosal tumours also occur. Optimal method of ER depends upon a range of factors including lesion location, size and morphology.
