摘要
总胆管和肝内胆管结石一般通过内窥镜取出。1, 2 其中一个原因是，由于工作通道的长度和大小，可用于球囊肠镜的设备有限。据报道，一种具有独特螺旋形状的新型取石篮（VolticCatch V；日本东京奥林巴斯医疗系统公司；图 1）可用于使用工作通道直径为 3.7 毫米的结肠镜为 SAA 患者取出胆管结石。之前使用 0.018 英寸导丝的 VolticCatch V 型无法通过短型单气囊肠镜（SIF-H290S；奥林巴斯医疗系统公司）直径为 3.2 毫米、长 152 厘米的工作通道，例如在困难的情况下无法形成环路，但改进后的型号可以通过（图 2）。我们报告了两例 SAA 患者使用这种带有 0.018 英寸导丝的取石篮成功取出胆管结石的病例，由于其独特的形状，可能成为 SAA 患者取出小胆管结石的首选。插入线圈鞘时，0.018 英寸导丝在曲线上受到的阻力很大（箭头）。(b）改进模型：线圈鞘的顶部为圆形，尾部为方形。插入线圈鞘时，0.018 英寸导丝在曲线上的阻力减弱。患者因胃癌接受了全胃切除术，并进行了 Roux-en-Y 重建。使用 SIF-H290S 进行了内镜逆行胰胆管造影术（ERCP）。胆管造影显示多处缺损。我们使用了机械碎石机和球囊导管，但结石滑过了靠近乳头的篮子和球囊。因此，在将导丝从 0.025 英寸改为 0.018 英寸后，我们使用了一种新型篮筐。在另一个病例中，一名 25 岁的女性因先天性胆道扩张接受了胆总管空肠吻合术。ERCP使用SIF-H290S进行取石。胆管造影显示右肝管缺损。我们使用带有 0.018 英寸导丝的新型篮子，轻松取出了肝内胆管结石。
The extraction of difficult bile duct stones in a patient with surgically altered anatomy using a novel retrieval basket and a short-type single-balloon enteroscopy
Sekine and colleagues report successful stone extraction using a novel retrieval basket and a short-type single-balloon enteroscope in a patient with surgically altered anatomy. Its unique shape makes the basket with a 0.018-inch guidewire the first choice for removal of small bile duct stones in patients with surgically altered anatomy.
