“…The balloon attached to the sliding tube was inflated to grip the intestine, and both the scope and the sliding tube were withdrawn in tandem to shorten the intestine. By repeating these steps, the endoscope was inserted deeper into the intestine [4][5][6] . To insert the endoscope into the large intestine, the abdomen was compressed manually or body position was changed as required.…”

“…First, double-balloon endoscopy (DBE) was developed by Yamamoto et al [3] . Subsequently, single-balloon endoscopy (SBE) was developed and applied clinically [4][5][6] . A balloon at the tip of a sliding tube or an overtube is inflated to grip the intestine, and both the scope and the sliding tube are simultaneously withdrawn, thus shortening the intestine.…”

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.

AIM:To investigate the safety and efficacy of endoscopic band ligation (EBL) for bleeding lesions in the small bowel.METHODS: This is a retrospective study evaluating EBL in six consecutive patients (three males, three females, 46-86 years of age) treated between May 2009 and February 2014: duodenal vascular ectasia; 1, jejunal bleeding diverticulum; 1, ileal Dieulafoy's lesion; 1 and ileal bleeding diverticula; 3. The success of the initial hemostasis was evaluated, and patients were observed for early rebleeding (within 30 d after EBL), and complications such as perforation and abscess formation. Follow-up endoscopies were performed in four patients. RESULTS:Initial hemostasis was successfully achieved with EBL in all six patients. Eversion was not sufficient in four diverticular lesions. Early rebleeding occurred three days after EBL in one ileal diverticulum, and a repeat endoscopy revealed dislodgement of the O-band and ulcer formation at the banded site. This rebleeding was managed conservatively. Late rebleeding occurred in this case (13 and 21 mo after initial EBL), and re-EBL was performed. Follow-up endoscopies revealed scar formation and the disappearance of vascular lesions at the banded site in the case with a duodenal bleeding lesion, and unresolved ileal diverticula in three cases. Surgery or transarterial embolization was not required without any complications during the median follow-up period of 45 (range, 2-83) mo. CONCLUSION:EBL is a safe and effective endoscopic treatment for hemostasis of bleeding lesions in the small bowel.© 2014 Baishideng Publishing Group Inc. All rights reserved.Key words: Endoscopic band ligation; Small bowel; Diverticular hemorrhage; Jejunal bleeding; Ileal bleeding; Therapeutic endoscopy; Hemostasis Core tip: There have been few reports regarding the use of endoscopic band ligation (EBL) for the treatment of bleeding lesions in the small intestine. The present study demonstrates safe and effective use of EBL to treat six patients with small bowel lesions including, duodenal vascular ectasia, ileal Dieulafoy's lesion, and jejunal and ileal bleeding diverticula. Although the bleeding was successfully managed in all patients, those with diverticular bleeding in the small bowel should be closely monitored after an initial EBL.

“…Nevertheless, it does enable us to provide a diagnosis in a large number of patients with undi- agnosed gastrointestinal bleeding, and it gives us the opportunity to treat bleeding, especially in vascular lesions. An alternative approach involves single-balloon enteroscopy (16,17), which enables us to explore a greater length of the small intestine, albeit with less efficacy than with the double-balloon technique.…”
