چکیده

Aim. To compare the efficacy of using computed tomography enteroclysis/enterography (CTE), capsule endoscopy (CE), and CTE with CE for diagnosing tumor lesions in the small intestine. Materials and Methods. We included 98 patients who underwent CE during the observation period and were subjected to CTE at our hospital from April 2008 to May 2014. Results. CTE had a significantly higher sensitivity than CE (84.6% versus 46.2%, P = 0.039), but there were no significant differences in specificity, positive or negative predictive values, or diagnostic accuracy rates. The sensitivity of CTE/CE was 100%, again significantly higher than that of CE (P = 0.002). The difference in specificity between CTE/CE and CE was not significant, but there were significant differences in positive predictive values (100% for CTE/CE versus 66.7% for CE, P = 0.012), negative predictive values (100% versus 92.1%, P = 0.008), and diagnostic accuracy rate (100% versus 89.8%, P = 0.001). The diagnostic accuracy rate was also significantly higher in CTE/CE versus CTE (100% versus 95.9%, P = 0.043). Conclusion. Our findings suggested that a combination of CTE and CE was useful for screening tumor lesions in the small intestine. This trial is registered with number UMIN000016154.

The Usefulness of Capsule Endoscopy for Small Bowel Tumors

Video capsule endoscopy (VCE) has expanded the range of endoscopic examination of the small bowel. The clinical application of VCE is mainly for obscure gastrointestinal bleeding (OGIB) and small bowel tumor is one of the clinically significant diagnoses of VCE, often requiring subsequent invasive interventions. Small bowel tumors are detected with a frequency of around 4% with VCE in indicatio...

Capsule Endoscopy for Crohn's Disease: Current Status of Diagnosis and Management

Crohn's disease (CD) is an idiopathic inflammatory bowel disease involving the small and/or large intestine. More than 50% of Western CD patients and up to 88% of Asian CD patients may have small intestinal involvement. Video capsule endoscopy (VCE) has a higher diagnostic yield than small bowel barium radiography and computed tomography enterography for the detection of small intestinal involv...

Meckel's diverticulum detected by computed tomographic enterography: report of 3 cases and review of the literature.

Meckel's diverticulum is a common anomaly of the small intestine and occasionally presents as obscure gastrointestinal hemorrhage. Before operation, it is difficult to diagnose by imaging, especially in adults. Conventional abdominal computed tomography and endoscopy have limitations for the diagnosis of Meckel's diverticulum. Diagnostic methods in patients with small bowel lesions include ente...

Effectiveness of Capsule Endoscopy Compared with Other Diagnostic Modalities in Patients with Small Bowel Crohn’s Disease: A Meta-Analysis

Background/Aims As a result of the rapid development of medical diagnostic tools, physicians require concrete evidence to evaluate the effectiveness of the tools. We aimed to investigate the effectiveness and additional diagnostic benefits of capsule endoscopy (CE) in patients with small bowel Crohn's disease (CD). Methods We performed a systematic search of databases, including MEDLINE, EMBA...

INFLAMMATORY BOWEL DISEASE Small bowel involvement in Crohn’s disease: a prospective comparison of wireless capsule endoscopy and computed tomography enteroclysis

Background: Wireless capsule endoscopy (WCE) offers endoscopic access to the small bowel and may therefore change diagnostic and therapeutic strategies in small bowel diseases. Aim: The aim of this prospective study was to validate the gain in information and therapeutic impact of WCE in patients with Crohn’s disease. Methods: Fifty six consecutive patients with Crohn’s disease underwent comput...
