ABSTRACT
GOALS: To compare the diagnostic yield and cost-consequences of 2 strategies, screening regardless of symptoms versus case finding (CF), using a point-of-care test (POCT), for the detection of celiac disease (CD) in primary care, to bridge the diagnostic gap of CD in adults. MATERIALS AND METHODS: All subjects under 75 years of age who consecutively went to their general practitioners' offices were offered POCT for anti-transglutaminase immunoglobulin A antibodies. The POCT was performed on all subjects who agreed, and then a systematic search for symptoms or conditions associated with higher risk for CD was performed, immediately after the test but before knowing the test results. The 2 resulting groups were: (a) POCT positive and (b) symptomatic subject at CF. Subjects were defined as symptomatic at CF in the presence of 1 or more symptoms. All POCT-positive or symptomatic subjects at CF were referred to the CD Centers for confirmation of CD. Data on resource consumption were gathered from patients' charts. Cost of examinations, and diagnostic and laboratory tests were estimated with regional outpatient tariffs (Sicily), and a price of &OV0556;2.5 was used for each POCT. RESULTS: Of a total of 2197 subjects who agreed to participate in the study, 36 (1.6%) and 671 (30.5%) were POCT positive and symptomatic at CF, respectively. The yield from the screening and CF was 5 new celiac patients. The total cost and mean cost for each new CD case were &OV0556;7497.35 and &OV0556;1499.47 for the POCT screening strategy, and &OV0556;9855.14 and &OV0556;1971.03 for the CF strategy, respectively. Assuming consecutive use of both strategies, performing POCT only in symptomatic subjects at CF, the calculated yield would be 4 new diagnoses with a total cost of &OV0556;2345.84 and a mean cost of &OV0556;586.46 for each newly diagnosed patient. Only 1 patient was celiac despite a negative POCT. CONCLUSIONS: Testing symptomatic subjects at CF only by POCT seems the most cost-effective strategy to bridge the diagnostic gap of adult CD in primary care.

INTRODUCTION: Device-assisted enteroscopy is a new endoscopic technique for the evaluation of small bowel in adults and children. Data in pediatric population are limited. This review aims to identify diagnostic and therapeutic benefits of enteroscopy in children. METHODS: We have analysed paediatric literature on device-assisted enteroscopy focusing on indications, technical aspects and complications, with attention given to adult publications that may be applicable to the paediatric population. RESULTS: Obscure gastrointestinal bleeding, Crohn's disease and small bowel polyps are the main indications of enteroscopy in children. Device-assisted enteroscopy has high diagnostic yield for the main paediatric indications, but MR-enterography and capsule endoscopy should be used beforehand in diagnostic work-up to better identify candidates for enteroscopy and to improve its diagnostic and therapeutic yield. Major complications are rare and mostly related to therapeutic procedures. CONCLUSION: Despite limited data in the paediatric population, device-assisted enteroscopy represents a useful and safe endoscopic technique in children. Its use, combined with MR-enterography and capsule endoscopy, allows identification and treatment of many of the small bowel paediatric diseases with a low risk of complications.
