Newly anchor deployment suturing device - current status and future perspectives-

Introduction -Endoscopic Full-thickness suturing is still challenging and we are engaging the new device from concept through development and assessing this functionality and efficacy.
The divice-The anchor deployment suturing device is designed to suture full-thickness through an endoscope channel. The sutures are achieved using threaded anchors with a reduced friction mechanism which enables easier tightening. The sutures are deployed in a simple and intuitive operation and this device enables the deployment of any number of sutures.
Materials and methods-The suturing for four locations in a pig model were conducted under anesthesia. The grasper was operated to grasp the sub-serosa tissue without penetrating the wall and a first anchor was deployed, full-thickness. The same procedure was performed as needed until each suture was completed. Z patterns suturing assuming closure and U patterns suturing assuming sleeve gastroplasty were attempted at the antrum, greater curvature, fundus, and duodenal bulb. After the last anchor was deployed, the suturing device was pulled out and the thread was cut using the cinch deployment mechanism.
Results-The abdominal cavity was accessed via a midline incision. All anchors were full-thickness. No leak and no puncture injuries were seen.
Conclusions-These preliminary findings demonstrate the potential for simple and safe full-thickness suture deployment. Such an instrument could revolutionize the suturing options.
