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.
Rectal Inspection
Begin by inspecting the perianal and anal areas for color, texture, rashes,...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the colonic...

Serum Laboratory Studies, Stool Test, Breath Test

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...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and solid...
Endoscopic Procedures II: Colonoscopy01:25

Endoscopic Procedures II: Colonoscopy

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:

Summary

A single fecal occult blood test (FOBT) in colonoscopy surveillance detected significant colorectal neoplasia in nearly 50% of participants. This method appears to identify additional pathology, improving colorectal cancer surveillance.

Area of Science:

  • Gastroenterology
  • Oncology
  • Preventive Medicine

Background:

  • Colonoscopic surveillance is crucial for high-risk individuals to prevent colorectal cancer.
  • Debate exists regarding optimal surveillance intervals and the detection rate of colorectal cancer within screening programs.

Purpose of the Study:

  • To evaluate if an interval fecal occult blood test (FOBT) aids in detecting significant neoplasia during colonoscopic surveillance.
  • To assess participant interest in interval screening and identify missed or rapidly developing lesions.

Main Methods:

  • Patients in a colonoscopic surveillance program underwent an immunochemical FOBT (Inform).
  • Positive FOBT results triggered a follow-up colonoscopy.
  • Significant neoplasia included colorectal cancer, large or complex adenomas, high-grade dysplasia, or multiple adenomas.

Main Results:

  • Nearly 50% of invited patients (47.8%) completed the FOBT.
  • 1.8% of FOBT completers were diagnosed with significant neoplastic lesions, including six colorectal cancers and eight adenomas.
  • Positive FOBT results led to the detection of additional pathology.

Conclusions:

  • An immunochemical FOBT is a viable tool for interval screening in colonoscopic surveillance programs.
  • This approach demonstrates a notable participation rate and detects significant colorectal neoplasia, particularly in patients with a history of polyps.
