Abstract:
Objective To evaluate the risk factors,treatment and follow-up of capsule retentions after capsule endoscopy examination.Methods A total of 1 100 capsule enteroscopic examinations,performed at our hospital from October 2006 to March 2013,were retrospectively studied.The positive findings of lesions, clinical indications of capsule endoscopy,treatment and follow-ups were recorded.Results The incidence of capsule retentions was 1.18%(n =13).The rates of capsule retentions in OGIB,suspected Crohn′s disease (CD),known CD,suspected tumors and chronic abdominal pain were 0.95%,4.0%,10.5%,7.1% and 0.3%,respectively.In 11 patients,the capsule was removed by means of double-balloon enteroscopy,the cap-sule was removed surgically in one patient,and spontaneous expulsion occurred in another patient after 1 year of treatment.Risk factors for capsule retention were known or suspected CD and suspected tumor(OR =11.44, P =0.02;OR =5.59,P =0.02),and suspected tumor was also a risk factor(OR =7.42,P =0.04).Conclu-sion Capsule endoscopy is a safe procedure with low risk of capsule retentions.Advantages and disadvantages of capsule endoscopy examinations should be considered carefully when high-risk patients are involved.
