Efficacy of duodenal bulb biopsy for diagnosis of celiac disease: a systematic review and meta-analysis.

Although duodenal biopsy is considered the "gold standard" for diagnosis of celiac disease, the optimal location of biopsy within the small bowel for diagnosis remains unclear. The primary aim of this study was to perform a structured systematic review and meta-analysis to evaluate the diagnostic utility of endoscopic duodenal bulb biopsy for celiac disease. Searches of PubMed, EMBASE, Web of Science, and Cochrane Library databases were performed from 2000 through December 2017.
