A 57-year-old woman underwent endoscopic sleeve gastroplasty using an endoscopic suturing device attached to a single-channel adult gastroscope. During the second bite, both the needle driver opening function and anchor exchange mechanism failed. This resulted in impaction of the device in the gastric wall and a “red-out” that obscured the visual field. An ultra-slim gastroscope was inserted transorally, enabling visualization of the impacted device ([Fig. 1], [Video 1]). A needle knife was passed through the channel port of the endoscopic suturing system and used to transect through the entrapped gastric tissue. Mini-forceps inserted through the ultra-slim gastroscope were used by a second endoscopist to manipulate the needle-knife catheter to extend the incision laterally and down to the level of the needle driver, thereby releasing the impacted device from the gastric wall ([Fig. 2]).

Ex-vivo examination revealed that the suture needle had become embedded between the anchor exchange catheter and the channel of the endoscopic suturing device ([Fig. 3]). This caused a misalignment between the needle driver and anchor exchange. Although misalignment occurs in 8.4 % of cases [2], it can be salvaged by retracting the anchor exchange a few centimeters before re-engaging the needle driver. In our case, the lodged suture needle created a fixed misalignment that could not be rectified. We show that a needle knife can be used safely to free an impacted device under direct endoscopic visualization, preventing the need for emergency surgical intervention.
