|June 8, 2017
Summary
Screening colonoscopy is a low-risk procedure, with rare complications like bleeding and perforation. This study assessed complications within four weeks of screening colonoscopy, finding the overall risk to be minimal.
Area of Science:
- Gastroenterology
- Public Health
- Medical Screening
Background:
- Screening colonoscopy has been available in Germany since 2002.
- Data on complications occurring after colonoscopy remain limited.
- Previous reports indicate complications during colonoscopy are infrequent.
Purpose of the Study:
- To determine the frequency of complications associated with screening colonoscopy.
- To assess complications occurring during and up to four weeks post-procedure.
- To provide comprehensive data on the safety of screening colonoscopy.
Main Methods:
- A cohort of 5527 individuals undergoing screening colonoscopy in Saarland, Germany (2010-2013) was studied.
- Participant questionnaires and medical record reviews were used to validate self-reported complications.
- Mortality follow-up was conducted for non-responders to the questionnaire.
Main Results:
- Among 5252 participants, 16 cases of bleeding (0.30%) and 4 cases of perforation (0.08%) were confirmed.
- Hospitalization due to bleeding occurred in 0.095% and perforation in 0.04% of cases.
- No deaths within three months of colonoscopy were attributed to the procedure.
Conclusions:
- The risk of complications from screening colonoscopy is low.
- This low risk profile is maintained even when considering a four-week post-procedure observation period.
- The study confirms the safety of screening colonoscopy in a large cohort.

923
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:

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
518
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...

01:25Assessment of the Rectum and Anus
1.5K
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.

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...

Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
