Abstract:
Objective To evaluate the clinical effect of capsule endoscopy(CE)followed by a directed double-balloon enteroscopy(DBE)in diagnosis of patients with suspected small bowel disease.Methods Two hundred and ninety-nine consecutive patients with obscure gastrointestinal bleeding or other various indications for CE examination were analyzed.DBE was recommended after negative or indeterminate evaluation on CE.The diagnostic and follow-up data were collected and analyzed.Resails A total of 296 patients completed CE examination.Of whorn,138(46.6%)cases had positive findings,68(23.0%)cases were suspected for small bowel disease and 90(30.4%)cases had negative finding,Those who were suspected(45 cases)and negative(7 cases)for CE examination were performed DBE examination and small bowel lesions were found in 31 cases and 1 case,respectively.The false-negative diagnosis was probably made by DBE in 8 patients,whereas no false-positive case was found by DBE.The false-negative diagnosis was probably made by CE in 2 patients,whereas 8 false-positive cases were found by CE.With the results of CE examination,lesions were found by only one-side procedure of DBE in 90.3%(28/31)of patients.The results that followed up for median 17 months indicated that 93.5% of patients with positive findings by DBE were received optimal therapy.Both CE and DBE procedures were well tolerated and no severe complications occurred.Conclusions The detection rate of sinall bowel lesions with CE was high,whereas the indetermination of CE findings was also significant.Majority of suspected findings by CE may be further confirmed by DBE.The strategy that start with CE and followed by DBE may increase diagnostic yield in patients with suspected small bowel disease and improve the prognosis.
