Assessment of the Rectum and Anus

2.0K
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,...

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

636
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...

Lower GI Series: Barium Enema

2.7K
A Barium Enema, or a lower GI series, is a specialized radiographic examination designed to visualize the lower gastrointestinal tract, specifically the colon and rectum. This procedure is instrumental in diagnosing various conditions such as colorectal cancer, polyps, diverticulosis, and inflammatory bowel disease.
Procedure Details
The examination begins by inserting a lubricated rectal tube into the patient's rectum to administer a radiopaque barium solution. The barium flow is carefully...

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:

Area of Science:

  • Gastroenterology
  • Radiology
  • Pelvic Floor Disorders

Background:

  • Obstructed defecation syndrome (ODS) presents diagnostic challenges.
  • It affects a significant subset of patients with chronic constipation.
  • Traditional evaluation methods for ODS can be difficult.

Purpose of the Study:

  • To evaluate the utility of Magnetic Resonance Defecography (MRD) in diagnosing ODS.
  • To identify common pelvic floor abnormalities in ODS patients.
  • To discuss the technique, findings, and limitations of MRD for ODS.

Main Methods:

  • Retrospective review of 192 consecutive patients undergoing MRD.
  • Data collected between January 2011 and January 2012.
  • Analysis of MRD scans and patient records.

Main Results:

  • MRD identified various pelvic floor dysfunctions in ODS patients.
  • Common findings included abnormal descent, rectoceles, and rectorectal intussusceptions.
  • Combinations of pathologies were frequently observed.

Conclusions:

  • MRD is a valuable tool for evaluating patients with ODS.
  • It effectively visualizes multiple pelvic floor abnormalities.
  • Understanding MRD findings is crucial for ODS patient management.
