“…Although robot assistance is thought to facilitate intracorporeal laparoscopic sewing [16], this remains the most demanding skill in minimally invasive surgery [17]. For this reason, several devices for extracorporeal [18] and intracorporeal stitching and knotting have been developed [19][20][21] that greatly facilitate the placing of interrupted sutures. For urinary diversions, however, running sutures are essential.…”

What's known on the subject? and What does the study add?• The EndoSew ® prototype was first tested in a porcine model several years ago. The investigators found it both simple to master and reliable, its greatest advantage being a 2.4-fold time saving compared with straight laparoscopic suturing. In addition to that publication, there is a single case report describing the performance of an open EndoSew ® suture to close parts (16 cm) of an ileal neobladder. The time for suturing the 16 cm ileum was 25 min, which is in line with our experience. The knowledge on this subject is limited to these two publications.• We report on the first consecutive series of ileal conduits performed in humans using the novel prototype sewing device EndoSew ® . The study shows that the beginning and the end of the suture process represent the critical procedural steps. It also shows that, overall, the prototype sewing machine has the potential to facilitate the intracorporeal suturing required in reconstructive urology for construction of urinary diversions. Objective• To evaluate the feasibility and safety of the novel prototype sewing device EndoSew ® in placing an extracorporeal resorbable running suture for ileal conduits. Patients and Methods• We conducted a prospective single-centre pilot study of 10 consecutive patients undergoing ileal conduit, in whom the proximal end of the ileal conduit was closed extracorporeally using an EndoSew ® running suture. • The primary endpoint was the safety of the device and the feasibility of the sewing procedure which was defined as a complete watertight running suture line accomplished by EndoSew ® only. Watertightness was assessed using methylene blue intraoperatively and by loopography on postoperative days 7 and 14.• Secondary endpoints were the time requirements and complications Յ30 days after surgery. Results• A complete EndoSew ® running suture was feasible in nine patients; the suture had to be abandoned in one patient because of mechanical failure.• In three patients, two additional single freehand stitches were needed to anchor the thread and to seal tiny leaks. Consequently, all suture lines in 6/10 patients were watertight with EndoSew ® suturing alone and in 10/10 patients after additional freehand stitches.• The median (range) sewing time was 5.5 (3-10) min and the median (range) suture length was 4.5 (2-5.5) cm.• There were no suture-related complications. Conclusions• The EndoSew ® procedure is both feasible and safe.• After additional freehand stitches in four patients all sutures were watertight.• With further technical refinements, EndoSew ® has the potential to facilitate the intracorporeal construction of urinary diversions.

“…Unfortunately, the slow adoption of LSKT can be attributed, in part, to limitations with laparoscopic technology [ 6 ]. Learning the traditional LSKT technique in a two-dimensional environment, particularly with restricted visibility and limited angles, can be an arduous and frustrating experience for inexperienced surgeons [ 7 ]. Despite the availability of numerous LSKT techniques, many of them cannot ensure sufficient knot stability.…”

“…Indeed, throughout the years, several devices, robotic systems, and alternatives to suturing have been developed, in order to allow easier and quicker knot tying. [10][11][12][13][14][15][16][17][18] Su2ura Approximation (Anchora Medical Ltd) is a novel device developed to utilize the insertion of anchors threaded with stitches to bypass the standard passing of a needle from one side of the tissue to the other as performed in traditional suturing (Figure 1; Supp Figure 1). This anchor feature allows a single action placement of a suture for easier MIS suturing, which is intended to help surgeons on a variety of MIS skill levels.…”

One of the challenging aspects of minimal invasive surgery (MIS) is intracorporal suturing, which can be significantly time-consuming. Therefore, there is a rising need for devices that can facilitate the suturing procedure in MIS. Su2ura Approximation Device (Su2ura Approximation) is a novel device developed to utilize the insertion of anchors threaded with stitches to allow a single action placement of a suture. The objective of this study was to evaluate the long-term safety and tissue approximation of Su2ura Approximation in comparison to Endo Stitch + Surgidac sutures in female domestic pigs. All incision sites were successfully closed by both methods. Firm consolidation within and around the incision site was noted in several animals in both treatment groups, which corresponded histopathologically to islands of ectopic cartilage or bone spicules within the fibrotic scar. These changes reflect heterotopic ossification that is commonly seen in the healing of abdominal operation sites in pigs. No other abnormal findings were observed throughout the study period. In conclusion, the use of Su2ura Approximation under the present experimental conditions revealed no safety concerns.
