To compare the clinical outcome of double-balloon colonoscopy (DBC) with conventional colonoscopy (CC) for colon evaluation performed by an unskilled colonoscopist.
Between June 2008 and November 2008, 1544 colonoscopies were performed in our hospital. Fifty-eight patients, (29 male and 29 female ; 19-86 years; mean age, 63 years) involving 60 intubations, were enrolled in this study and were assigned randomly to the DBC or CC group. One first-year GI fellow was enrolled and performed these 60 consecutive colonoscopies (30 DBCs, 30 CCs). Completion rate of colonoscopy, cecal intubation time, and rate of analgesic agent usage were analyzed.
Completion of DBC was 100% (30/30), while completion of CC was 73% (22/30). There was a statistically significant difference (p < 0.05). The mean cecal intubation time was 36.2 +/- 14.4 minutes (DBC) and 36.5 +/- 15.2 minutes (CC). There was no statistically significant difference. Analgesic agent was used with 19 intubations (63%) (DBC) and with 27 intubations (90%) (CC) (p < 0.05).
For inexpert endoscopists, using DBC has a higher rate of effectiveness than using CC and can decrease the discomfort of patients during colonoscopic procedures.
比较非熟练结肠镜检查者使用双气囊结肠镜（DBC）和传统结肠镜（CC）进行结肠评估的临床结果。
2008年6月至2008年11月期间，我院共进行了1544例结肠镜检查。本研究纳入了58例患者（29例男性和29例女性；年龄19 - 86岁，平均年龄63岁），涉及60次插管，并将其随机分配至DBC组或CC组。一名第一年的胃肠病学住院医师参与并连续进行了这60次结肠镜检查（30次DBC，30次CC）。分析了结肠镜检查的完成率、盲肠插管时间和镇痛药使用比例。
DBC的完成率为100%（30/30），而CC的完成率为73%（22/30）。两者存在统计学显著差异（p < 0.05）。平均盲肠插管时间为36.2±14.4分钟（DBC）和36.5±15.2分钟（CC）。无统计学显著差异。DBC组19次插管（63%）使用了镇痛药，CC组27次插管（90%）使用了镇痛药（p < 0.05）。
对于不熟练的内镜医师，使用DBC比使用CC具有更高的成功率，并且可以减轻结肠镜检查过程中患者的不适。
