Abstract
Background: The advent of double-balloon enteroscopy has enabled more accurate diagnosis and treatment of
small bowel disorders. Single-balloon enteroscopy permits visualization of the entire small intestine less often than
does double-balloon enteroscopy. However, the relative clinical advantages of the 2 methods remain controversial.
This study therefore aimed to identify the indications for and therapeutic impact of performing single-balloon
enteroscopy.
Methods: We retrospectively reviewed prospectively collected data from adults who underwent single-balloon
enteroscopy from January 2007 through November 2011 and analyzed their baseline characteristics, endoscopic
findings, pathological diagnoses, and clinical outcomes.
Results: A total of 145 procedures were performed in 116 patients with a mean age of 58.1 ± 17.7 years (range,
18–89 years). The most common indications for performing single-balloon enteroscopy were overt gastrointestinal
(GI) bleeding, chronic diarrhea, and occult GI bleeding, accounting for 57.9%, 12.4%, and 9.7% of the patients,
respectively. The area of interest was achieved in 80.7% of the cases, with a 5.5% rate of technical failure. An overall
positive finding was detected in 65.5% of the cases, of which 33.8% were ulcers and erosions; 8.3%, masses; and
3.4%, angiodysplasia. The diagnostic yields were 42.9%, 52.4%, 78.6%, 50.0%, and 25.0% for patients with overt
GI bleeding, occult GI bleeding, abdominal pain, chronic diarrhea, and abnormal imaging results, respectively.
Therapeutic procedures were performed in 11% of patients with GI bleeding and achieved a therapeutic yield of
14.6% with a minor complication rate of 11.7%.
Conclusions: Single-balloon enteroscopy was effective for the diagnosis and treatment of small bowel disorders,
especially in patients who presented with abdominal pain, GI bleeding, or focal abnormalities on imaging scans.
