摘要
Colonoscopy is a risk factor for colon ischemia.The colon is susceptible to ischemia due to its minor blood flow compared to other abdominal organs;the etiology of colon ischemia after colonoscopy is multifactorial.The causative mechanisms include splanchnic circulation impairment,bowel preparation,drugs used for sedation,bowel wall ischemia due to insufflation/barotrauma,and introduction of the endoscope.Gastroenterologists must be aware of this condition and its risk factors for risk minimization,early diagnosis,and proper treatment.
