A multicenter, prospective trial of total colonoscopy using a short double-balloon endoscope in patients with previous incomplete colonoscopy

Regional center for complex colonoscopy: yield of neoplasia in patients with prior incomplete colonoscopy

“…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.…”

Assessment of the impact of technical factors on the quality of colonoscopy – a preliminary report

“…Some studies attempted to investigate the possible influence of different instruments on cecal intubation rate and time [6]. The difference in adenoma detection rate was studied too, but using different types of endoscopes (instruments of different generations: high resolution vs. standard resolution [10,11] or standard instruments vs. instruments with the ability to use additional techniques such as narrow band imaging (NBI), auto fluorescence imaging (AFI), or retrograde viewing [12][13][14][15][16][17]). …”

When Colonoscopy Fails… Refer, Repeat, and Succeed

“…The success rate of cecal intubation ranges between 85.7 and 100% with adenoma detection rates between 11.8 and 54.2%, in keeping with the data from the current study. There is large heterogeneity in study populations and endoscopic techniques with many studies of small volume (7–70) and often using balloon enteroscope or other special endoscopes [4-6]. Rex and colleagues clearly show that most repeat examinations can be safely completed with standard paediatric or adult colonoscopes, with gastroscopes used in 11%, primarily in situations such as severe stenotic or fixed acutely angulated diverticular disease.…”
