Colonoscopy-induced ischemic colitis in patients without risk factors

Area of Science:

• Gastroenterology
• Vascular Medicine
• Colorectal Surgery

Background:

• Ischemic colitis is the most frequent type of intestinal ischemia.
• It typically affects the elderly and those with predisposing vascular or systemic conditions.
• Risk factors include vascular occlusion, shock, certain medications, and hematologic disorders.

Observation:

• This report presents two rare cases of ischemic colitis.
• These cases occurred after routine screening colonoscopies.
• Notably, the patients lacked pre-existing risk factors for ischemia.

Findings:

• Colonoscopy, while generally safe, can be a rare trigger for ischemic colitis.
• The mechanism in patients without risk factors remains unclear.
• This suggests a need for vigilance even in low-risk individuals.

Implications:

• Highlights a potential, albeit rare, complication of colonoscopy.
• May prompt further investigation into the pathogenesis of post-colonoscopy ischemic colitis.
• Underscores the importance of considering ischemic colitis in patients presenting with abdominal pain post-procedure, regardless of traditional risk factors.
