Abstract:
Small bowel endoscopy, including small bowel capsule endoscopy (SBCE) and balloon‐assisted endoscopy (BAE), is useful for small bowel bleeding (SBB) assessment. However, the specific management strategy for overt SBB is not well established. This meta‐analysis aimed to evaluate the pooled diagnostic yields (DYs) and therapeutic yields (TYs) of small bowel endoscopy in overt SBB and to determine the optimal endoscopy timing. Methods A comprehensive literature search was performed of studies examining the DY and/or TY of small bowel endoscopy in overt SBB. Data on the DY, TY, and timing of small bowel endoscopy were extracted, pooled, and analyzed. The pooled DY and TY of small bowel endoscopy for patients with overt SBB were calculated. Meta‐regression and subgroup analysis were performed. Results Twenty‐two studies were included. The pooled DY was 65.2% and 74.0% for SBCE and BAE, respectively. The pooled TY of SBCE and BAE was 55.9% and 35.8%, respectively. A meta‐regression model showed that the timing of endoscopy was significantly associated with the DY of BAE and the TY of SBCE and BAE. Conclusions Small bowel capsule endoscopy and BAE would be useful diagnostic and therapeutic modalities in overt SBB. According to the subgroup analysis, in which the TY seemed to be higher within 2 days after bleeding for SBCE and BAE, the optimal timing of endoscopy would be within 2 days.
