Summary
Patients with advanced colorectal polyps show poor understanding of their cancer risk and family screening needs. Endoscopists are key to improving this knowledge for better colorectal cancer prevention.
Area of Science:
- Gastroenterology
- Oncology
- Public Health
Background:
- Advanced colorectal polyps increase personal and familial risk of colorectal neoplasia.
- Professional guidelines recommend intensive surveillance and earlier screening for relatives.
- Understanding patient and family risk perception is crucial for adherence to guidelines.
Purpose of the Study:
- To assess knowledge of personal and familial colorectal cancer (CRC) risk among patients with advanced polyps.
- To evaluate awareness of recommended surveillance and screening protocols.
- To identify predictors of accurate knowledge regarding CRC risk and recommendations.
Main Methods:
- An online survey assessed knowledge and risk perception related to CRC.
- The survey included 37 items, expert-reviewed and pilot-tested.
- Data from 137 patients under 60 with advanced polyps were analyzed using regression.
Main Results:
- Only 28.5% recognized their polyp as precancerous; 54.8% felt at higher CRC risk.
- Awareness of family member risk (40.1%) and need for earlier screening (38.0%) was low.
- Endoscopists were the primary information source, but few recommended family screening.
Conclusions:
- Patients with advanced colorectal polyps demonstrate inadequate knowledge of personal and familial CRC risks and guidelines.
- Endoscopists play a vital role in educating patients and their families about CRC risks and screening.
- Targeted educational interventions by endoscopists can improve risk communication and adherence to surveillance.

01:25Assessment of the Rectum and Anus
940
Evaluating the rectum and anus plays a crucial role in conducting a thorough physical examination of the gastrointestinal system. Although it may be uncomfortable and often embarrassing for the patient, it holds immense diagnostic value, particularly in detecting gastrointestinal diseases and abnormalities. This guide will explain how to perform this assessment using inspection and palpation methods.

02:59Cancer Prevention
7.5K
Several factors can increase the risk of cancer in an individual. About 50% of cancer cases can be prevented by adopting a healthy lifestyle, regular exercise, eating healthy, and following a modest cancer prevention diet. Epidemiological studies have consistently shown that populations with vegetable and fruit-rich diets have reduced the incidence of cancer. On the other hand, populations who have a diet rich in animal fat, red meat, junk food, or high calories are predisposed to cancer.

01:21Barrett Esophagus-I: Introduction
497
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

483
The colon, or large intestine, is the final segment of the digestive system. Its primary functions include absorbing water and vitamins produced by gut bacteria and transforming waste from liquid to solid to form stool. In adults, the large intestine is approximately 5 feet long and consists of four main sections:

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
