Self-administered disposable micro-enemas before outpatient sigmoidoscopy
Journal of the Royal Society of Medicine
|November 1, 1996
Summary
Mailing micro-enemas before rigid sigmoidoscopy significantly improves diagnostic yield by ensuring adequate bowel preparation. This simple intervention enhances visualization and reduces examination limitations caused by faeces, saving patient reattendances.
Area of Science:
- Gastroenterology
- Colorectal Surgery
- Diagnostic Imaging
Background:
- Rigid sigmoidoscopy is crucial for diagnosing colorectal carcinomas.
- Faecal presence and recto-sigmoid bend negotiation are key limitations.
- Effective bowel preparation is essential for diagnostic accuracy.
Purpose of the Study:
- To evaluate the efficacy of pre-procedure micro-enema administration for improving rigid sigmoidoscopy.
- To assess the impact of micro-enemas on bowel preparation quality and diagnostic yield.
- To determine if micro-enemas reduce examination limitations and subsequent reattendances.
Main Methods:
- A prospective study comparing 78 unprepared patients with 101 patients receiving a mailed Microlax enema.
- Patients self-administered enemas before outpatient appointments.
- Bowel preparation grade, sigmoidoscope height, and faecal limitation were recorded.
Main Results:
- Adequate visualization was achieved in 88% of enema recipients versus 53% of unprepared patients (P < 0.001).
- Micro-enema use significantly increased the height achieved by the sigmoidoscope.
- The percentage of sigmoidoscopies not limited by faeces was significantly higher in the enema group.
Conclusions:
- Mailed micro-enemas are a cost-effective method to enhance rigid sigmoidoscopy diagnostic yield.
- This intervention improves bowel preparation, visualization, and procedure success.
- Utilizing micro-enemas can reduce the need for patient reattendance.

01:26Imaging 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...

01:29Endoscopic Procedures I: Esophagogastroduodenoscopy
An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

01:25Endoscopic 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:
01:28Endoscopic Procedures III: Video Capsule Endoscopy
Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...
01:26Endoscopic 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...

01:23Lower GI Series: Barium Enema
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...
