“…While endoclips were successfully used to gather the mucosa around the fistula after filling the fistula with PGA sheets [7,13], such a procedure carries a risk of inducing incomplete closure. Recently, more powerful closure devices, such as the over-the-scope-clipping system and the endoscopic suturing technology, have been developed and demonstrated the availability for GI fistula closure in spite of concerns, including the technical difficulty, cost and long-term outcomes [16][17][18][19][20]. Such alternative techniques in combination with filling PGA sheets can help improve the long-term outcomes if these devices come to be easily and generally used in terms of technique and cost.…”

Background: This retrospective study aimed to investigate the suitable indications, methodology and long-term effect of the closure of gastrointestinal (GI) fistulas using polyglycolic acid (PGA) sheets and fibrin glue (FG) and to evaluate the usefulness of a delivery technique using a guidewire. Methods: It involved 10 applications in six patients (median age 73 (range 53-78) years old, three men) with GI fistulas. A guidewire was introduced endoscopically or percutaneously into the fistula beyond the opposite orifice of the fistula with radiologic control. A tapered catheter was inserted over the guidewire, and the fistula was cleaned with an adequate quantity of saline. Subsequently, a small piece of PGA sheet was skewered onto the guidewire at the center and then pushed using the tapered catheter over the guidewire and delivered into the fistula. In cases of endoscopic procedure, the mucosa around the fistula was ablated, and the orifice of the fistula along with the surrounding mucosa was shielded with a piece of PGA sheet fixed with hemoclips and FG. Results: Technical success of fistula closure was achieved in all applications, and no complications were observed after the procedure. The long-term occlusion of the fistula was ultimately achieved in four of six patients at 202-654 days (median duration, 244 days) after the last procedure with one or two applications. Conclusions: The closure of GI fistulas using PGA sheets and FG demonstrated long-term efficacy for upper GI fistula of a certain length, and the filling technique using a guidewire ensured a safe smooth procedure.

“…Suturing and knotting in traditional Natural Orifice Transluminal Endoscopic Surgery (NOTES) is mainly done by endoscopy and human hands. 1 In NOTES, suturing is usually made with purse strings, which are easy to operate, the surface after suturing is smooth and promotes healing. Currently, the purse-string method is implemented with titanium clips, which are easily operated and accurately positioned.…”

Background: Suturing and knotting in Natural Orifice Transluminal Endoscopic Surgery (NOTES) requires the robot not only to be able to work with multiple manipulators but also to have a high degree of dexterity. However, little attention has been paid to the design and enhancement of dexterity in multi-manipulated robots. Methods:In this paper, the dexterity of a new dual-manipulator collaborative continuum robot in collaborative space is analyzed and enhanced. A kinematic model of the continuum robot was developed. The dexterity function of the robot is evaluated based on the concepts of the low-Degree-of-Freedom Jacobian matrix.Then an Adaptive Parameter Gray Wolf Coupled Cuckoo Optimization Algorithm with faster convergence and higher accuracy is innovatively proposed to optimize the objective function. Finally, experiments demonstrate that the dexterity of the optimized continuum robot is enhanced. Results:The optimization results show that the optimized dexterity is 24.91% better than the initial state. Conclusion:Through the work of this paper, the robot for NOTES can perform suturing and knot more dexterously, which has significant implications for the treatment of digestive tract diseases.
