Colonoscopies are widely available, but there are cases where insertion can be difficult, even for experienced endoscopists. EC-760XP/L, a new ultrasmall-diameter long scope, may be useful in such cases. This single-center retrospective study included 39 cases where colonoscope insertion was difficult even when previously conducted by an experienced endoscopist. The primary outcome was the cecal intubation time using EC-760XP/L compared to the time used in a previous examination with a standard scope. The secondary outcomes were the cecum intubation rate, intestinal cleanliness level, adenoma detection rate, polyp detection rate, sedative use rate, occurrence of adverse events, and pain experience. A comparison of cecal intubation times between EC-760XP/L and the standard scope showed that insertion times were significantly lower with EC-760XP/L (9.5 min) compared to the standard scope (19 min) (p < 0.01). The standard scope achieved cecal intubation in 30 cases (76.9%), whereas EC-760XP/L reached the cecum in all cases (p < 0.01). Pain was observed in 3 cases (8.3%) with the EC-760XP/L, which was significantly lower than the 22 cases (56.4%) with the standard scope (p < 0.01). In conclusion, EC-760XP/L proved to be useful in cases where colonoscope insertion was difficult.
结肠镜检查广泛可用，但在某些情况下，即使是经验丰富的内镜医生也难以插入。EC-760XP/L 是一种新型的超小直径长内镜，在这种情况下可能会很有用。这项单中心回顾性研究纳入了 39 例即使由经验丰富的内镜医生进行也难以插入结肠镜的病例。主要结局是使用 EC-760XP/L 与之前使用标准内镜检查时的盲肠插管时间。次要结局是盲肠插管率、肠道清洁度水平、腺瘤检出率、息肉检出率、镇静剂使用率、不良事件发生率和疼痛体验。EC-760XP/L 与标准内镜相比，盲肠插管时间明显更短（EC-760XP/L 为 9.5 分钟，标准内镜为 19 分钟）（p<0.01）。标准内镜在 30 例（76.9%）中成功插管，而 EC-760XP/L 在所有病例中均到达盲肠（p<0.01）。EC-760XP/L 组有 3 例（8.3%）出现疼痛，明显低于标准内镜组的 22 例（56.4%）（p<0.01）。总之，EC-760XP/L 在结肠镜插入困难的情况下是有用的。
