Is ileocecal valve intubation essential for routine colonoscopic examination?

Area of Science:

• Gastroenterology
• Endoscopy
• Diagnostic Yield

Background:

• Routine colonoscopies are performed to assess various gastrointestinal conditions.
• The diagnostic value of terminal ileum intubation during these procedures is not always fully utilized.

Purpose of the Study:

• To evaluate the diagnostic yield of terminal ileum intubation during routine colonoscopies.
• To determine the incidence of abnormalities in the terminal ileum in a large patient cohort.

Main Methods:

• A prospective study involving 1310 patients undergoing colonoscopy.
• Terminal ileum intubation was routinely performed, with data on intubation rates, time, and findings collected.
• Endoscopic and histopathologic evaluations of the terminal ileum were conducted.

Main Results:

• Successful terminal ileum intubation was achieved in 90.2% of cases.
• Endoscopic abnormalities were detected in 6% of patients, significantly more in symptomatic individuals (7%) versus asymptomatic (3.3%).
• Histopathologic examination revealed significant findings in 22 cases, including 12 diagnoses of Crohn's disease.

Conclusions:

• Terminal ileum intubation during colonoscopy offers significant diagnostic value, particularly in symptomatic patients.
• The procedure is recommended for patients presenting with chronic diarrhea, iron-deficiency anemia, abdominal pain, or suspected inflammatory bowel disease.
