Rupture of the spleen after colonoscopy: a life-threatening complication.
During colonoscopy, the risk of injuring the spleen or other viscera except the colon is negligible. We report here a patient in whom spleen rupture did complicate the very early course of colonoscopy, but this remains an extremely rare complication with no more than 50 cases so far described. Diagnosis may be difficult, and the risk of spleen rupture seems to be greatest within 24 hours of colonoscopy. Mechanisms leading to spleen injury in the setting of colonoscopy are unclear; however, direct trauma, colon distension by insufflated air, and the excessive traction on the splenocolic ligament may be involved. Patients with splenomegaly and those with preexisting adhesions are at greater risk for this complication. Patients complaining of persistent abdominal pain after colonoscopy should be closely monitored and aggressively investigated for the suspect of spleen injury and rupture.
