There is no specific insertion method for patients who previously underwent an incomplete colonoscopy. No multicenter prospective study using a double-balloon endoscope (DBE) for total colonoscopy was previously performed.
To demonstrate the effectiveness and safety of using short DBEs in patients who previously underwent incomplete colonoscopies.
A multicenter, prospective trial.
Four tertiary care academic centers and 6 community hospitals.
Patients with a history of incomplete colonoscopy, ages 20 to 79 years, were included. Exclusion criteria were colonoscopy performed by endoscopists with experience in fewer than 1000 cases, history of colectomy, poor bowel preparation, inflammatory bowel disease, active bowel obstruction, and active bleeding.
Total colonoscopies using short DBEs were attempted in all patients.
Primary endpoint was the cecal intubation rate. Secondary endpoints were time to cecal intubation, complications, and tolerability.
A total of 110 patients (62 males, median age 66.5 years) were included. Fifty-four patients had a history of abdominal surgery. The cecal intubation rate was 100% (110/110). Median intubation time was 12 minutes (range 4-47 minutes). Mild mucosal tears without symptoms occurred in 1 patient. For 64.5% of patients, intravenous sedatives and/or analgesics were used during examinations. Based on questionnaires, 50.9% had no pain, 31.8% slight pain, and 17.3% tolerable pain. Moreover, 96.4% of patients answered that their examination was more comfortable than their previous colonoscopy.
Uncontrolled trial.
The use of a short DBE is an effective and safe method for total colonoscopy in patients who previously underwent incomplete colonoscopies. (

对于先前接受过不完全结肠镜检查的患者，尚无特定的插入方法。以前没有使用双球囊内镜（DBE）进行全结肠镜检查的多中心前瞻性研究。
证明在先前接受过不完全结肠镜检查的患者中使用短 DBE 的有效性和安全性。
多中心前瞻性试验。
四家三级保健学术中心和六家社区医院。
年龄在 20 至 79 岁之间，有不完全结肠镜检查史的患者入选。排除标准为接受结肠镜检查的内镜医师经验少于 1000 例，结肠切除术史，肠道准备不佳，炎症性肠病，活动性肠梗阻和活动性出血。
所有患者均尝试使用短 DBE 进行全结肠镜检查。
主要终点是盲肠插管率。次要终点是盲肠插管时间，并发症和耐受性。
共有 110 名患者（62 名男性，中位年龄 66.5 岁）入选。54 例有腹部手术史。盲肠插管率为 100％（110/110）。中位插管时间为 12 分钟（范围 4-47 分钟）。1 例患者出现轻度黏膜撕裂，但无明显症状。在检查过程中，64.5％的患者使用了静脉镇静剂和/或镇痛药。根据问卷调查，50.9％的患者没有疼痛，31.8％的患者有轻微疼痛，17.3％的患者可以忍受疼痛。此外，96.4％的患者回答说他们的检查比以前的结肠镜检查更舒适。
未对照试验。
对于先前接受过不完全结肠镜检查的患者，使用短 DBE 进行全结肠镜检查是一种有效且安全的方法。（
