Double-balloon enteroscopy: Experience with an innovative endoscopic technique at the Hospital Universitario de la Fundación Santa Fe de Bogotá

Introduction and aims: Double-balloon enteroscopy is a recently introduced endoscopic method that enables complete visualization of the small bowel, as well as biopsy sampling and therapeutic interventions in that part of the intestine. The aim of the present study was to describe the experience acquired at our hospital to determine the characteristics of the patients that underwent the procedure.

Materials and methods: A descriptive, cross-sectional study was conducted on all patients above 18 years of age admitted to the Hospital Universitario de la Fundación Santa Fe de Bogotá for double-balloon enteroscopy, within the time frame of January 2013 to December 2017.

Results: The study sample included 93 procedures in 73 patients. Mean patient age was 57.91 years, with a similar number of men and women. There were no severe complications. The most frequent indication for the enteroscopy was gastrointestinal bleeding (overt or occult), presenting in 49.46% of the patients, followed by chronic diarrhea (16.13%). Video capsule endoscopy was the previous study most frequently performed (53.76%). Anterograde double-balloon enteroscopy was carried out in 49 patients and 44 patients underwent the retrograde procedure. A total of 86.02% of the enteroscopies were diagnostic procedures and 13.98% were therapeutic. Normal enteroscopy was the most frequent finding (59.68%), followed by the presence of ulcers (15.05%).

Conclusions: Our results were similar to those reported worldwide, with respect to indications, insertion route, and insertion depth, and there were no severe complications.
