ARTICLE HIGHLIGHTS
Research background
There are three different methods for the management of disorders in the distant part of small bowel: Double-balloon enteroscopy (DBE), single-balloon enteroscopy (SBE), and spiral enteroscopy (SE).
Research motivation
The efficacy of the three methods in terms of diagnostic and therapeutic yield rates, total enteroscopy rate, depth of maximal insertion, time to maximum insertion, and examination time remains unclear.
Research objectives
We aimed to compare the efficacy of DBE, SBE, and SE for the management of small bowel diseases.
Research methods
We searched randomized controlled trials and prospective studies in MEDLINE, PubMed, Embase, Cochrane Library, and Chinese CQVIP database. Statistical analyses were performed via RevMan software.
Research results
The diagnostic and therapeutic yields did not differ significantly when comparing DBE with SE and DBE with SBE. Total enteroscopy, examination time, time to maximum insertion, and depth of maximal insertion were similar between SBE and DBE. DBE was superior to SE with regard to depth of maximal insertion, with longer time to maximum insertion and examination time.
Research conclusions
DBE and SBE may have similar clinical outcomes. Compared with DBE, SE seems to have similar diagnostic and therapeutic yields, but shorter procedural time in cost of less depth of insertion.
Research perspectives
SE needs further evaluation vs SBE. DBE is recommended for complete enteroscopy.
