Successive Suture Device for Gastrointestinal Endoscopes

Background/Aims: Recently, treatment using an endoscopic device is actively being developed. Techniques for incision and bleeding control have been developed, but endoscopic suturing remains to be perfected. Using an endoscopic suturing technique, a variety of diseases could be managed noninvasively. We have attempted to use a new endoscopic suturing device which enables a continuous suture using a flexible upper endoscope. Methods: A suturing device was designed where a semicircular needle could sew through tissue by rotation making a continuous suture possible. Results: We successfully sutured the stomach tissue of a dog using an optimized suturing device model. Conclusions: The initial model was found to have some problems. However, we hope to develop a continuous suturing device for flexible upper endoscope procedures in Korea.
