BACKGROUND Conventional lesion-up colorectal ESD has the potential risk of iatrogenic perforation due to the knife's direction toward the muscular layer of the bowel wall. If we rotate the endoscope to the proper position, the mucosal flap is easy to be lifted down by tip attachment and the knife is easy to approach the proper dissection plane, which may prevent the perforation and facilitate difficult ESD. METHODS We aimed to retrospectively assess the safety and efficacy of this rotating technique compared with the conventional lesion-up dissection regardless of shape, location, or size of the tumor, and investigated in short- and long-term outcomes following the ESD procedure. RESULTS 41 lesions were enrolled into rotating technique group and 37 lesions in lesion-up group. The dissection speed was significantly faster in the rotating technique group (p = 0.023). R0 resection rate was significantly higher in rotating technique group (p = 0.008). The rate of perioperative complication was significantly higher in lesion-up method group (p = 0.003). Local recurrence was higher in lesion-up group (p = 0.001). Recurrence-free rate was higher in rotating technique group (p = 0.018). CONCLUSION The endoscope rotating is a useful technique for difficult colorectal ESD due to easy approaching the proper dissection plane. This technique also increases the rate of en bloc resections, R0 resections regardless of size, shape, and location and improves dissection speed without increasing the incidence of adverse events.

内窥镜旋转技术对结直肠内镜困难的黏膜下剥离非常有用。

背景技术由于刀朝向肠壁的肌肉层的方向,传统的病灶向上的结直肠ESD具有潜在的医源性穿孔的风险。如果我们将内窥镜旋转到合适的位置,则粘膜瓣很容易通过尖端连接器提起,并且刀很容易接近正确的解剖平面,这可能会阻止穿孔并导致难以进行的ESD。方法我们旨在回顾性评估这种旋转技术与常规病变向上剥离术的安全性和有效性,无论其形状,位置或肿瘤大小如何,并在ESD手术后进行短期和长期预后调查。结果旋转技术组41例,向上病变组37例。旋转技术组的解剖速度明显更快(p = 0.023)。旋转技术组的R0切除率显着更高(p = 0.008)。病灶向上方法组的围手术期并发症发生率明显更高(p = 0.003)。病变部位组的局部复发率更高(p = 0.001)。旋转技术组的无复发率更高(p = 0.018)。结论内窥镜旋转是一种易于解决的结直肠ESD有用的技术,因为它容易接近正确的解剖平面。该技术还可以提高整体切除率,R0切除率,而与大小,形状和位置无关,并且可以提高解剖速度,而不会增加不良事件的发生率。病灶向上方法组的围手术期并发症发生率明显更高(p = 0.003)。病变部位组的局部复发率更高(p = 0.001)。旋转技术组的无复发率更高(p = 0.018)。结论内窥镜旋转是一种易于解决的结直肠ESD有用的技术,因为它容易接近正确的解剖平面。该技术还可以提高整体切除率,R0切除率,而与大小,形状和位置无关,并且可以提高解剖速度,而不会增加不良事件的发生率。病灶向上方法组的围手术期并发症发生率明显更高(p = 0.003)。病变部位组的局部复发率更高(p = 0.001)。旋转技术组的无复发率更高(p = 0.018)。结论内窥镜旋转是一种易于解决的结直肠ESD有用的技术,因为它容易接近正确的解剖平面。该技术还可以提高整体切除率,R0切除率,而与大小,形状和位置无关,并且可以提高解剖速度,而不会增加不良事件的发生率。结论内窥镜旋转是一种易于解决的结直肠ESD有用的技术,因为它容易接近正确的解剖平面。该技术还可以提高整体切除率,R0切除率,而与大小,形状和位置无关,并且可以提高解剖速度,而不会增加不良事件的发生率。结论内窥镜旋转是一种易于解决的结直肠ESD有用的技术,因为它容易接近正确的解剖平面。该技术还可以提高整体切除率,R0切除率,而与大小,形状和位置无关,并且可以提高解剖速度,而不会增加不良事件的发生率。
