Serrated lesions and serrated polyposis syndrome.

[Serrated polyps and serrated polyposis syndrome].

Serrated polyps of the colorectum are a heterogeneous group of lesions with potential malignant transformation through the «serrated pathway» of carcinogenesis. The discovery of these lesions has been a paradigm shift in the concept of the adenoma-carcinoma sequence, so that up to 30% of tumors develop through this pathway. The main factors associated with an increased risk of malignancy in ser...

A Case with Serrated Polyposis Syndrome Controlled by Multiple Applications of Endoscopic Mucosal Resection and Endoscopic Submucosal Dissection

BACKGROUND Serrated polyposis syndrome (SPS) is characterized by numerous hyperplastic polyps and sessile serrated adenoma/polyp (SSA/P) in the large intestine. SSA/P is known to transform into malignant lesions through the serrated pathway instead of the adenoma-carcinoma sequence. Early diagnosis with lower gastrointestinal endoscopy and early treatment are now considered to be essential. CAS...

Serrated polyposis syndrome associated with long-standing inflammatory bowel disease.

Inflammatory bowel disease (IBD) patients are at an increased risk of developing colorectal cancer (CRC), which is thought to develop via the adenoma-carcinoma pathway. Since the discovery of the serrated carcinogenesis pathway and serrated polyposis syndrome (SPS), the incidence of carcinomas arising from serrated lesions in IBD patients has increased. We report three cases of long-standing IB...

Reassessment colonoscopy to diagnose serrated polyposis syndrome in a colorectal cancer screening population.

Background and study aims Serrated polyposis syndrome (SPS) is a high risk condition for colorectal cancer (CRC). Surveillance strategies for patients with serrated lesions remain controversial. We aimed to evaluate a diagnostic strategy to detect SPS consistently during reassessment colonoscopy in patients with proximal serrated lesions. Methods This was a retrospective study of all individual...

British Society of Gastroenterology position statement on serrated polyps in the colon and rectum

Serrated polyps have been recognised in the last decade as important premalignant lesions accounting for between 15% and 30% of colorectal cancers. There is therefore a clinical need for guidance on how to manage these lesions; however, the evidence base is limited. A working group was commission by the British Society of Gastroenterology (BSG) Endoscopy section to review the available evidence...
