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.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

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:

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...

Summary
This summary is machine-generated.

Inadequate bowel preparation affects colonoscopy quality for many. This review found device-assisted methods and oral sennosides offer higher success rates for salvage strategies in colon cleansing.

Published on: August 1, 2019

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Medical Research

Background:

  • Adequate bowel preparation is crucial for high-quality colonoscopy.
  • A significant percentage of patients experience inadequate bowel preparation.
  • Salvage strategies are needed to improve colon cleansing effectiveness.

Purpose of the Study:

  • To identify and evaluate evidence on salvage strategies for inadequate bowel preparation.
  • To determine the success rates of various rescue approaches.

Main Methods:

  • A literature search was conducted using Medline and Google Scholar.
  • Studies published in English were included.
  • Success rates of salvage approaches were calculated and pooled.

Main Results:

  • Overall adequate colon cleaning was achieved in 79.3% of patients across 17 studies (2,167 patients).
  • Success rates varied by approach: oral high-volume polyethylene glycol (PEG) at 78.1%, low-volume PEG at 75.3%, oral sennosides at 82.5%, and device-assisted preparation at 84.6%.

Conclusions:

  • Nearly 20% of patients do not achieve effective bowel cleansing.
  • Multiple salvage strategies exist, but none consistently ensure adequate preparation for all patients.
  • Device-assisted and sennoside-based approaches show promising success rates.
