Usefulness of cap-assisted colonoscopy during colonoscopic EMR: a randomized, controlled trial

New Developments in Mechanical Enhancement of Colonoscopy: Cuffs, Caps and Rings

“…Three studies including 2 prospective RCTs [7,8] and 1 retrospective study [9] , all from Germany describing the EC were included for the review. Six prospective RCTs, 1 each from Germany [10] , Hong Kong [11] , Netherlands [12] , US [13] , South Korea [14] , Australia [15] and 1 retrospective study from Hong Kong [16] describing the CAC were included for the review. One multicenter (Netherlands, Israel and US) RCT describing ERC was also included [17] .…”

“…Diagnostic colonoscopies included, but were not limited to symptoms of abdominal pain and evaluation of anemia [7][8][9] . Regular colonoscopies with technical difficulty in polyp resection [14] or failure of cecum intubation [16] were also included.…”

“…Prior to the prep, subjects in Frieling et al [10] , Lee et al [11] and Park et al [14] were on a 3-day low residue diet and then given 4 liters of MoviPrep or 90 ml of phospho soda [10,11] . Tee et al [15] used a 1-day clear diet, sodium phosphate or picosulfate-based prep with 8 h of fasting.…”

“…The mean dose of diazepam used in both CAC and RC was 2.6 mg (±2.6). Midazolam and fentanyl were used in 4 studies [13][14][15]17] . Other agents like meperidine [14] , propofol [15] and hyoscine butylbromide [15] as an antispasmodic were also used.…”

“…Midazolam and fentanyl were used in 4 studies [13][14][15]17] . Other agents like meperidine [14] , propofol [15] and hyoscine butylbromide [15] as an antispasmodic were also used. All studies discussed above showed no significant differences in the dose of anesthetic and analgesic needed between the 2 groups of colonoscopies except for Floer et al [7] , where a median dose of 150 mg of propofol was used in the EC subgroup versus 170 mg in the SC subgroup which was statistically significant.…”
