Assessment of the Rectum and Anus01:25

Assessment of the Rectum and Anus

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.

Skin Cancer01:30

Skin Cancer

Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
Basal Cell Carcinoma (BCC): BCC is the most common type of skin cancer, accounting for about 80% of cases. It typically develops in...

Summary
This summary is machine-generated.

Tattooing polyps 10 mm or larger during colonoscopy is recommended for patients in the national bowel cancer screening programme. This practice improves the localization of potentially invasive colorectal cancer, enhancing patient outcomes.

Area of Science:

  • Gastroenterology
  • Oncology
  • Endoscopic procedures

Background:

  • Current guidelines for colonoscopy polyp tattooing lack size-specific recommendations.
  • Endoscopists rely on polyp appearance and size to determine the need for future localization.
  • This study addresses the relationship between polyp size and invasive colorectal cancer to refine tattooing practices.

Purpose of the Study:

  • To determine the relationship between endoscopic polyp size and invasive colorectal cancer.
  • To inform tattooing practices for the national bowel cancer screening programme (BCSP).
  • To establish evidence-based criteria for polyp tattooing during colonoscopy.

Main Methods:

  • Retrospective analysis of BCSP patients who underwent polypectomy between 2008-2010.
  • Data collected from a hospital endoscopic database and electronic patient records.
  • Inclusion of histology data to assess polyp malignancy and dysplasia.

Main Results:

  • A total of 269 polypectomies were performed on 165 patients.
  • The risk of invasive malignancy increased significantly with polyp size: 0.7% (<10 mm), 2.4% (10-19 mm), and 13% (>20 mm).
  • Only 23% of polyps were tattooed, with malignant or high-grade dysplasia polyps frequently missed.

Conclusions:

  • Endoscopic polyp size is a significant predictor of invasive colorectal cancer risk in BCSP patients.
  • A polyp size of 10 mm or greater is associated with a statistically significant increase in cancer risk.
  • Recommendation to tattoo all polyps measuring 10 mm or larger to improve detection and management.
