De acuerdo a la definición de la OMS se estableció el diagnóstico de síndrome de poliposis serrada (SPS) por la presencia de más de 20 pólipos serrados de cualquier tamaño distribuidos a lo largo del colon. Debido a la multiplicidad de lesiones de gran tamaño a predominio de colon derecho y a la topografía de uno de ellos a nivel del orificio apendicular, que condiciona su

Serrated Polyposis Syndrome in a Single-Center 10-Year Experience
AIMS Serrated polyposis syndrome is a disease that is often missed in the clinical setting and is associated with colorectal cancer. We investigated the prevalence of SPS and the association between colorectal or other cancers in a 10-year, retrospective data analysis. METHODS We reviewed complete colonoscopy data obtained from January 2005 through January 2015 at a health-screening centre. S...
متن کاملSerrated polyposis: colonic phenotype, extracolonic features, and familial risk in a large cohort.
BACKGROUND Serrated polyposis is a poorly understood and likely underdiagnosed condition. Little is known regarding the colorectal cancer risk, extracolonic phenotype, and cause of serrated polyposis. OBJECTIVE The aim of this study is to describe the clinical and family history features of a large cohort of individuals with serrated polyposis. DESIGN This is a retrospective cohort study fr...
متن کاملSerrated 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...
متن کامل[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...
متن کاملDevelopment of invasive colon cancer with microsatellite instability in a patient with hyperplastic polyposis syndrome.
The serrated pathway has recently been proposed as a route for the development of colorectal cancer with microsatellite instability. Hyperplastic polyposis syndrome is a rare syndrome defined by the presence of numerous serrated polyps, with a high risk of developing into colorectal cancer. We present here a case of hyperplastic polyposis syndrome developing into colorectal cancer with microsat...
متن کاملA 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...
