Double balloon enteroscopy: is it efficacious and safe in a community setting?

AIM
Double balloon enteroscopy (DBE) has been extensively used in tertiary referral centers but little literature exists on the efficacy, complications and outcomes of patients undergoing DBE in the community setting. We present our findings regarding the use of DBE in a community hospital.


METHODS
From March 2007 to January 2011, 88 DBE procedures were performed on 66 patients. Indications included evaluation anemia/gastrointestinal bleed, small bowel IBD and dilation of strictures. Video-capsule endoscopy (VCE) was used prior to DBE in 43 of the 66 patients prior to DBE evaluation.


RESULTS
The mean age was 62 years. Thirty-two patients were female, 15 were African-American; 44 antegrade and 44 retrograde DBEs were performed. The mean time per antegrade DBE was 107.4±30.0 minutes with a distance of 318.4±152.9 cm reached past the pylorus. The mean time per lower DBE was 100.7±27.3 minutes with 168.9±109.1 cm meters past the ileocecal valve reached. Endoscopic therapy in the form of electrocautery to ablate bleeding sources was performed in 20 patients (30.3%), biopsy in 17 patients (25.8%) and dilation of Crohn's-related small bowel strictures in 4 (6.1%). 43 VCEs with pathology noted were performed prior to DBE, with findings endoscopically confirmed in 32 cases (74.4%). In 3 cases the DBE showed findings not noted on VCE.


CONCLUSION
DBE appears to be equally safe and effective when performed in the community setting as compared to a tertiary referral center with a comparable yield, efficacy, and complication rate.
