The diagnosis and treatment of obscure gastrointestinal bleeding using total enteroscopy with double balloon enteroscopy / 中华消化内镜杂志

ABSTRACT

Objective To investigate the feasibility and application value of total enteroscopy with double balloon enteroscopy(DBE)for diagnosis and treatment of patients with obscure gastrointestinal bleeding(OGIB). Methods The clinical and endoscopic data of patients underwent DBE for OGIB in the Department of Gastroenterology,Remin Hospital of Wuhan University from January 2010 to December 2015 were retrospectively analyzed. Results Total enteroscopy was indicated in 36.3%(136/375)of patients. The success rate was 86.0%(117/136)and complication rate was 1.5%(2/136). Negative findings,non-small bowel lesions and small bowel lesions were detected in 44.4%(52/117), 6.8%(8/117), and 48.7%(57/117)of patients with total enteroscopy. Re-bleeding occurred in 8.9%(4/45)of patients with negative total enteroscopy,while 1 small bowel mesenchymoma and 1 gastric fundus Dieulafoy′s lesion were revealed subsequently. Re-bleeding occurred in 33.3%(5/15)of patients with incomplete enteroscopy,and 1 small bowel polyp and 1 small bowel angiectasis were revealed subsequently. Conclusion DBE can complete total enteroscopy within one day and provide important clinical information of OGIB. Non-small bowel lesions,small bowel lesion missed by DBE and potential bleeding lesions in small bowel beyond the reach of DBE should be considered in patients with negative enteroscopy.
