Clinical consequences of videocapsule endoscopy in GI bleeding and Crohn's disease.

BACKGROUND: Videocapsule endoscopy (VCE) has a high diagnostic yield in the analysis of GI bleeding and Crohn's disease. Little information is available on the impact of VCE findings on clinical care. OBJECTIVE: Assess the impact of VCE findings on clinical management and outcome. DESIGN: Retrospective descriptive study. SETTING: General hospital. PATIENTS: VCE was performed in 150 patients for GI bleeding (n = 97), Crohn's disease (n = 36), and miscellaneous reasons (n = 17). MAIN OUTCOME MEASUREMENTS: Clinical consequences were evaluated by using a questionnaire and were divided into change of management or unchanged management. Change of medication, endoscopic procedures, surgical procedures, other consequences, and avoidance of additional investigations were considered a change of management. For all patients, an assessment of the actual clinical condition and the most recent Hb level were registered. RESULTS: A definite diagnosis was established in 34%, a probable diagnosis in 34%, and no diagnosis in 32%. Management was changed in 38% of patients, increasing to 59% if a definite diagnosis was established at VCE. No relation between change of management and clinical improvement or increased Hb level could be established. LIMITATIONS: The start of ethinylestradiol/norethisterone in case of telangiectasia was considered a change of management, although controversy on the rationale of this treatment exists. A more detailed and objective evaluation of the clinical condition should be performed to assess the clinical outcome. CONCLUSIONS: VCE findings have a serious impact on clinical practice. VCE in particular leads to a change of management in 59% of the patients in whom a definite diagnosis is established.

Detection of small-bowel neuroendocrine tumors by video capsule endoscopy.

OBJECTIVES: Carcinoid tumors are the most common GI neuroendocrine tumors (NET). They often originate in the small intestine. The primary tumor is often difficult to locate, and resection in an early phase is recommended to prevent complications. This study evaluated the value of videocapsule endoscopy (VCE) in the detection of small-intestinal primary carcinoid tumor. DESIGN: Prospective descriptive study. SETTING: Tertiary referral center. PATIENTS: Twenty consecutive patients (13 men, 7 women; 60.5 +/- 9.3 years) with metastatic NET of unknown primary tumor. INTERVENTIONS: All patients underwent CT, enteroclysis, nuclear imaging, and VCE of the small bowel. RESULTS: CTs and enteroclysis did not detect a primary small-intestinal carcinoid tumor. Nuclear imaging demonstrated abnormalities in the abdominal area in 13 patients but was unable to relate this to an intestinal localization in any patient. VCE revealed a small-intestinal tumor in 9 patients. Three other patients showed external compression and erosions. At surgery, 5 patients had a small-intestinal carcinoid tumor, and, in 2 patients, a small-intestinal ischemic segment was present. LIMITATIONS: The number of false-positive VCE findings was not clear, because not all patients underwent surgery. The absence of abnormalities at VCE in patients with abnormalities at nuclear imaging might be related to the presence of carcinoid tumor restricted to the mesenterium or to a false-negative VCE. CONCLUSIONS: VCE had a high diagnostic yield of 45% for identification of primary small-intestinal carcinoid tumors. Although nuclear imaging had a comparable diagnostic yield, it could not differentiate between intestinal and mesenterial localization of the carcinoid.
