“…We previously reported that the use of a colonoscope with an outer diameter of 9.2 mm and an effective length of 1600 mm (CF-PQ260L ® , Olympus Co., Tokyo, Japan) allowed total colonoscopy to be performed in the majority of patients in whom scope insertion was precluded by an elongated colon and adhesions [13] . Preliminary studies have suggested that the use of a guide-wire-directed endoscope or a spiral overtube can facilitate colonoscope insertion when difficulty is en-useful [21] . In addition to diagnostic procedures such as biopsy, SBE allowed colorectal polyps to be endoscopically resected with no problems or complications.…”

AIM:To evaluate the clinical usefulness of singleballoon endoscopy (SBE) in patients in whom a colonoscope was technically difficult to insert previously. METHODS:The study group comprised 15 patients (8 men and 7 women) who underwent SBE for colonoscopy (30 sessions). The number of SBE sessions was 1 in 7 patients, 2 in 5 patients, 3 in 1 patient, 4 in 1 patient, and 6 in 1 patient. In all patients, total colonoscopy was previously unsuccessful. The reasons for difficulty in scope passage were an elongated colon in 6 patients, severe intestinal adhesions after open surgery in 4, an elongated colon and severe intestinal adhesions in 2, a left inguinal hernia in 2, and multiple diverticulosis of the sigmoid colon in 1. Three endoscopists were responsible for SBE. The technique for inserting SBE in the colon was basically similar to that in the small intestine. The effectiveness of SBE was assessed on the basis of the success rate of total colonoscopy and the presence or absence of complications. We also evaluated the diagnostic and treatment outcomes of colonoscopic examinations with SBE. RESULTS:Total colonoscopy was successfully accomplished in all sessions. The mean insertion time to the cecum was 22.9 ± 8.9 min (range 9 to 40). Abnormalities were found during 21 sessions of SBE. The most common abnormality was colorectal polyps (20 sessions), followed by radiation colitis (3 sessions) and diverticular disease of the colon (3 sessions). Colorectal polyps were resected endoscopically in 15 sessions. A total of 42 polyps were resected endoscopically, using snare polypectomy in 32 lesions, hot biopsy in 7 lesions, and endoscopic mucosal resection in 3 lesions. Fifty-six colorectal polyps were newly diagnosed on colonoscopic examination with SBE. Histopathologically, these lesions included 2 intramucosal cancers, 42 tubular adenomas, and 2 tubulovillous adenomas. The mean examination time was 48.2 ± 20.0 min (range 25 to 90). Colonoscopic examination or endoscopic treatment with SBE was not associated with any serious complications.CONCLUSION: SBE is a useful and safe procedure in patients in whom a colonoscope is technically difficult to insert.

“…Balloon endoscopy has previously been reported to be useful for colonoscopy in patients with a history of difficulty in colonoscope insertion [16][17][18][19][20][21][22][23] . Most studies used a DBE, but two studies conducted in the United State and Holland reported the results of SBE [22,23] .…”

“…9 Some previous studies have described techniques and yields of repeat colonoscopy in patients with prior incomplete colonoscopies 6,[16][17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] . Our series has several strengths, including its large size (this series accounts for more than half of all reported cases) and referral of all cases from other gastroenterologists and surgeons.…”

“…There have been many case reports describing the utility of BE for completion of colonoscopy after an incomplete examination with a conventional colonoscope [5][6][7][8] . BE is useful because it can hold and shorten a complicated and elongated bowel segment, and therefore can be used in patients with difficult colonoscopies.…”

Key words: difficult colonoscopy, single balloon enteroscopy, large intestine Abbreviations: BE, balloon enteroscopy; SBE, single balloon enteroscopy; CT, computed tomography Balloon enteroscopy (Be) was originally developed for observation of the deep small intestine, and has recently been utilized for difficult cases of total colonoscopy due to reasons such as adhesions and elongation. In this report, we present our experience with single balloon enteroscopy (sBe) to facilitate successful colonoscopy when standard techniques failed. In two cases, early colon cancers were detected in the cecum by sBe and were removed endoscopically or surgically. a third case is discussed in which sBe was attempted but was ultimately not successful. In that case, total colonoscopy was not performed because of looping in the sigmoid and transverse colon. a fourth case in which sBe was performed in order to remove colonic gas in a patient with megacolon. In that case, total colonoscopy could not be completed because the sBe balloon could not "grab" the dilated colon and therefore could not advance. sBe is a useful adjunct to standard colonoscopy in challenging cases, but has limitations and does not always ensure success.

Double-balloon colonoscopy after failed conventional colonoscopy: a pilot series with a new instrument

Abstract: Double-balloon colonoscopy enables full colonic examination in almost all patients with a previous incomplete colonoscopy. The overtube should be used in most cases. The use of fluoroscopic assessment of scope progression could be reduced further with increasing experience.
