Results of total colonoscopy in the diagnosis of polyps. Case studies in Villavicencio, Colombia

Revista de la Facultad de Medicina, 2017
Introduction: Any elevation above the normal plane of the colonic mucosa is considered a polypoid projection. As age increases, polyps are more likely to be found; in addition, polyps larger than 1 cm of diameter may potentially lead to a malignant ...

Roux‐en‐Y gastrojejunostomy and jejunojejunostomy for pyloric obstruction bypass in a horse and a foal

Equine Veterinary Journal, EarlyView.
Abstract Background Gastric outflow obstruction in horses is a rare but challenging condition, often resulting from either congenital anomalies or acquired lesions such as chronic ulceration or pyloric polyps. Conventional surgical bypass procedures, including gastrojejunostomy (GJ) or gastroduodenostomy and less commonly duodenojejunostomy, can ...

A Different Kind of Colon Polyp

Gastroenterology, 2012
Question: An asymptomatic, 74-year-old woman with type 2 diabetes was referred for endoscopic colorectal cancer screening. Colonoscopy revealed a 30-mm, polypoid, firm lesion in the transverse colon (Figure A), a 20-mm similar lesion in the cecum (Figure B), and a 12-mm lesion in the ascending colon. The polyps were not suggestive of adenomatous tissue

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

International Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

Artificial Intelligence in Colonoscopy Surveillance for Lynch Syndrome: Emerging Evidence, Lessons Learned From Average‐Risk Populations, and Future Directions

International Journal of Cancer, EarlyView.
ABSTRACT Lynch syndrome (LS) is the most common hereditary colorectal cancer (CRC) syndrome and is characterized by an accelerated adenoma‐carcinoma sequence, a relatively higher prevalence of flat and subtle CRC precursor lesions, and exceptionally high adenoma miss rates despite intensive colonoscopy surveillance.

The Importance of CT Pneumocolon in Detecting Colonic Lesions

Diyala Journal of Medicine, 2021
Background: Colonic masses are clinically important because some of them are malignant and others have a tendency to become malignant such as polyps. CT pneumocolon may have a role in the evaluation and diagnosis of these masses.

Rising Incidence and Mortality of Colorectal Cancer Among Younger Adults: A Population‐Based Study in Taiwan, 1994–2018

International Journal of Cancer, EarlyView.
Colorectal cancer incidence and mortality have increased in the Asia‐Pacific region over the past three decades. This population‐based study in Taiwan suggests a shift of the colorectal cancer burden towards the younger generations. An age–period–cohort model revealed higher annual increases in incidence (3.58%) and mortality (1.0%) rates among ...

Immunohistochemical characterization of the proliferative activity in epithelial and stromal cells of distal colonic polyps

Zaporožskij Medicinskij Žurnal
Colorectal cancer (CRC) remains a leading cause of cancer-related mortality worldwide. Colonic polyps are known to be potential precursors to CRC. Evaluating cellular proliferative activity across various polyp types and normal mucosa is essential for ...

Colorectal Cancer Screening in Hereditary and Familial High‐Risk Populations: Best Practices and Future Directions

International Journal of Cancer, EarlyView.
ABSTRACT Colorectal cancer (CRC) remains a leading cause of cancer‐related morbidity and mortality worldwide yet is largely preventable through effective screening and surveillance. While most CRC cases are sporadic, a substantial proportion occur in individuals at increased risk due to hereditary cancer syndromes or family history who require tailored

Evaluation of Mutation Risk Using Patient‐Derived Organoids in Patients With Lynch Syndrome

International Journal of Cancer, EarlyView.
ABSTRACT Lynch syndrome (LS) is a hereditary cancer predisposition syndrome caused by germline mutation of DNA mismatch repair (MMR) genes, most notably associated with colorectal cancer. Although LS patients face high risk of CRC, risk can vary even among those with the same pathogenic MMR germline mutations. We suggest a functional assay platform for
