| Inflammatory diseases1 | 92 (48.4%) | 23 (25.0%) | 83 (90.2%) | <0.05 |

1Inflammatory diseases include ulcers/erosions (n = 78), Crohn's disease (n = 10), intestinal tuberculosis (n = 2), ulcerative colitis (n = 1), and inflammatory bowel disease (n = 1).
2Gastrointestinal tumors/polyps include neoplasm (n = 3), gastrointestinal stromal tumors (n = 14), lymphoma (n = 3), metastatic tumors (n = 2), pancreatic tumor (n = 1), gastrointestinal carcinoma (n = 7), leiomyoma (n = 1), multiple prominences (n = 1), polyps (n = 6), Peutz-Jeghers syndrome (n = 2), and familial polyposis (n = 1).
3Four of the sixteen patients were Meckel's diverticulum.
4Others include incomplete intestinal obstruction (n = 2), intestinal bleeding (n = 1), ancylostomiasis (n = 1), connective tissue disease (n = 1), anaphylactoid purpura (n = 1), ileal duplication (n = 1), pancreatitis (n = 2), and functional gastrointestinal disorders (n = 13).
5As the diagnostic yield of DBE for diverticulum was 100% and was considered to be constant quantity in SPSS, χ 2-test was not applicable.
