Abstract
AIM: To assess diagnostic value of capsule endoscopy (CE) combined with computed tomography enterography (CTE) for small bowel diseases.
METHODS: One hundred and fourteen patients with suspected small bowel diseases underwent CE and CTE examinations (interval time 2-7 d). The diagnostic accuracy for small bowel diseases was compared between CE and CTE, based on pathological or follow-up results. The diagnostic accuracy of combined CE and CTE was also estimated.
RESULTS: The symptoms of enrolled patients included obscure gastrointestinal bleeding (OGIB, 35 cases), unexplained abdominal pain (32 cases), suspected Crohn's disease (29 cases) and unexplained weight loss (18 cases). For OGIB, CE had a higher diagnostic accuracy than CTE (51.4% vs 40.0%, P < 0.05). The diagnostic accuracy reached 57.1% when the two methods were combined. For unexplained abdominal pain, diagnostic accuracy was comparable between CE and CTE (46.9% vs 40.6%, P > 0.05). The diagnostic accuracy reached 59.3% when the two methods were combined, which was higher than that of CE or CTE alone. For suspected Crohn's disease, CE had a higher diagnostic accuracy than CTE (86.2% vs 65.5%, P < 0.05). The diagnostic accuracy reached 93.1% when the two methods were combined, which was higher than that of CTE alone.
CONCLUSION: Both CE and CTE prove to be effective procedures for patients with suspected small bowel disease, but the diagnostic value of CE is higher than that of CTE for OGIB and suspected Crohn's disease. The combination of CE and CTE may be a better strategy.
