Summary
Defecography effectively identifies various anorectal disorders, revealing abnormalities like rectocele and rectal intussusception in patients with constipation and defecation issues.
Area of Science:
- Gastroenterology
- Radiology
- Colorectal Surgery
Background:
- Anorectal disorders present a range of symptoms impacting defecation.
- Accurate diagnosis is crucial for effective treatment of these conditions.
Purpose of the Study:
- To evaluate the utility of defecography in diagnosing anorectal disorders.
- To identify common defecographic findings in patients with constipation and other defecation abnormalities.
Main Methods:
- Retrospective analysis of 27 patients undergoing defecography between June 1989 and February 1999.
- Assessment of anorectal angle (at rest and straining), rectal configuration abnormalities (rectocele, intussusception, infolding, ulceration), and pelvic floor descent.
Main Results:
- Abnormalities were common, including abnormal anorectal angle (5 cases), rectocele (15 cases), rectal intussusception (3 cases), infolding (11 cases), ulceration (7 cases), and anal canal constriction (1 case).
- Constipation was the most frequent indication (24 patients).
Conclusions:
- Defecography is a valuable imaging tool for demonstrating diverse rectal abnormalities in patients with anorectal disorders.
- The study highlights the prevalence of specific findings such as rectocele and rectal infolding.

01:25Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.

01:25Assessment 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.

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...

01:25Endoscopic 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:
01:23Lower 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...
