Risks of perforation and bleeding
Endoscopic intervention on the colon carries a risk of structural damage. Particular caution must be exercised when performing therapeutic manipulations, specifically the coagulation of bleeding vessels, as excessive thermal exposure sharply increases the likelihood of organ wall perforation.
In acute inflammatory bowel processes, performing endoscopy is strictly inadvisable due to the critically high risk of bowel rupture. In such situations, contrast-enhanced computed tomography becomes the method of choice. Resuming endoscopic examination is permitted only one month after the acute phase of inflammation has completely subsided.
Diagnostic features in bowel pathologies
In chronic inflammatory processes, endoscopic examination aims at early detection of tumors and verification of inflammatory bowel diseases. During the examination, morphological verification via mucosal biopsy sampling is a mandatory standard.
Radiological methods are also actively employed to assess the digestive tract state. Magnetic resonance imaging and contrast-enhanced computed tomography are used to detect severe complications such as:
- abdominal abscesses and infiltrates;
- enteroenteric fistulas;
- perforations and strictures.
Quality of care criteria
Standards for examining patients with severe bowel pathologies (e.g., Crohn's disease) require a comprehensive approach. At the primary stage, an examination by a gastroenterologist or coloproctologist is mandatory, including a digital rectal examination in the presence of perianal lesions or fistulas.
The instrumental examination stage necessarily includes colonoscopy with mandatory visualization of the terminal ileum. In cases of discrepancy between the clinical picture of massive bleeding and sparse endoscopic findings, re-analysis of video recordings or repeat procedures is used to accurately locate the source.
Safety rule: "Do not touch an acutely inflamed organ with a probe for a month, and coagulate wisely!"
Class and exam questions
Why is colonoscopy contraindicated in acute inflammatory bowel diseases?
This is due to the high risk of perforation of the thinned and inflamed bowel wall. In such cases, contrast-enhanced CT is performed, and endoscopy is postponed for at least a month.
What are the main therapeutic capabilities of colonoscopy in bleeding?
The method allows for coagulation or clipping of the bleeding vessel, but coagulation should be used with caution.
Which part of the bowel must be examined during colonoscopy according to care standards?
A mandatory condition is the visualization of the terminal ileum.
