Comparison of Single- Versus Double-Balloon Assisted-Colonoscopy for Colon Examination After Previous Incomplete Standard Colonoscopy

Abstract

For patients with incomplete conventional colonoscopy, SBC and DBC offer high cecal intubation rates as well as detection of additional polyps and therapeutic capability. Either SBC or DBC can be considered after incomplete conventional colonoscopy.

Double-balloon endoscopy

“…This might better reflect the real common daily practice than other studies reporting the experience of only one or a few performing endoscopists. Our findings on caecal intubation confirm the results of previous retrospective and prospective studies on DBE [14][15][16][17][18][19]23] with caecal intubation rates of 88-95%. Recently a 100% success rate of caecal intubation using a short double-balloon endoscope in 110 patients was reported [21].…”

“…Various other endoscopes were tested to complete the colonoscopy: paediatric colonoscopes [10], gastroscopes [11], variable stiffness colonoscopes [12] and push enteroscopes [13], as well as magnet-imaging-enhanced colonoscopy [14]. In recent years balloon-assisted endoscopy, double balloon as well as single balloon, has also been applied [8,[14][15][16][17][18][19][20][21][22][23]. The double-balloon endoscope was originally designed to overcome the problem of looping when inserting the endoscope into the small intestine [24].…”

Single- Versus Double-Balloon-Assisted Colonoscopy After Previous Incomplete Standard Colonoscopy

“…Comparative analysis of SBC versus DBC following incomplete colonoscopy may be necessary both for the endoscopists who have to choose between SBC and DBC and for endoscopy centers which have to determine one platform for SBC or DBC. While SBC required less time than DBC, the difference was not statistically significant in the current study [24]. However, a larger randomized controlled trial may be warranted to clarify any difference in performance outcomes between SBC and DBC after an incomplete colonoscopy.…”

“…For a balloon-assisted colonoscopy, two types of balloon enteroscopes are available; the double-balloon enteroscope developed by Yamamoto et al [16], and the single-balloon enteroscope developed by Tsujikawa et al [17]. The reported success rates of single-(SBC) or doubleballoon-assisted colonoscopy (DBC) in patients with previous incomplete conventional colonoscopy range from 88 to 100 % [18][19][20][21][22][23].In the current issue of Digestive Diseases and Sciences, Dzeletovic et al [24] compared the performance outcomes of SBC and DBC in patients with previous incomplete conventional colonoscopy. In this study, the authors retrospectively reviewed 26 cases of SBC and 27 cases of DBC in patients whom underwent failed conventional colonoscopy.…”
