Single-balloon enteroscopy in management of small-bowel disorders.

Abstract

Device-assisted enteroscopy including single-balloon enteroscopy (SBE) allows direct visualization of the small bowel and has good safety and efficacy in experienced hands. Our study is aimed to share our single-centre experience of SBE in diagnosing and treating small-bowel disorders. We reviewed the prospectively collected data (from December 2016 to December 2019) of 180 consecutive anterograde and/or retrograde procedures. Analysis of baseline characteristics, endoscopic findings, and diagnostic and therapeutic rates was done. SBE was done in 158 patients with a median age of 55years (range, 13-94years) for suspected small-bowel lesions. Dual enteroscopy (anterograde plus retrograde) was done in 22 patients (13.92%). The indication for the procedure was obscure gastrointestinal bleeding in 129 (71.66%), chronic unexplained abdominal pain in 20 (11.11%), suspected small-bowel abnormality in the form of narrowing and/or mass on imaging in 10 (5.5%), chronic diarrhea in 9 (5%), unexplained iron deficiency anemia in 9 (5%), and retained capsule in 2 (1.11%). The most common finding was ulcer, which was noted in 45 (25%) patients followed by stricture in 8 (4.44%) and both ulcers and strictures in 6 (3.33%) patients. SBE was normal in 61 (33.88%) patients. SBE gave a diagnosis in 66.11% while in 28.43% cases, therapeutic intervention was done. Minor complications like bleeding were noted in 3 patients and mild acute pancreatitis in 2 patients. Jejunal perforation requiring surgical intervention was noted in 1 patient. SBE is a safe and effective procedure in diagnosing and treating small-bowel diseases.
