The ability to place sutures under EUS control might allow development of a new type of transluminal endosurgery. The aim of this study was to develop endoscopic methods for suturing to variable predetermined depths in the wall of the GI tract and to allow fixation of adjacent hollow organs under EUS control.
A suturing device was constructed for suturing under EUS control to any desired depth. Sutures can also be placed into hollow or solid organs within 5 cm of the endoscope tip. The device allows multiple sutures to be placed without withdrawing the endoscope. Stitching, knot-tying, and thread-cutting are achieved through a 2.8-mm accessory channel.
Multiple (>100) sutures were placed in predetermined gut wall layers in pigs. Sutures were placed in the gallbladder (n = 7) and small intestine (n = 8) to fix the gallbladder/small intestine to the stomach and allow traction for the insertion of stents and other devices through the 2 lumens.
A new method for stitching under flexible EUS control is described. This technology was used to place sutures at precise depths in the GI tract. It allowed fixation of other organs to the accessible GI tract for various purposes including delivery of stents and devices for creating anastomoses.
在超声内镜（EUS）控制下放置缝线的能力可能会促成一种新型腔内手术的发展。本研究的目的是开发在内镜下将缝线缝合至胃肠道壁不同预定深度的方法，并在EUS控制下实现相邻中空器官的固定。
构建了一种用于在EUS控制下缝合至任何所需深度的缝合装置。缝线也可放置在内镜尖端5厘米范围内的中空或实体器官中。该装置允许在不拔出内镜的情况下放置多根缝线。通过一个2.8毫米的附件通道完成缝合、打结和剪线操作。
在猪的预定肠壁层中放置了多根（>100）缝线。在胆囊（n = 7）和小肠（n = 8）中放置缝线，将胆囊/小肠固定于胃，以便通过两个腔道牵引插入支架和其他装置。
描述了一种在柔性EUS控制下进行缝合的新方法。该技术用于在胃肠道中精确深度处放置缝线。它可将其他器官固定于可及的胃肠道，用于多种目的，包括输送支架以及创建吻合口的装置。
