Project description:Video Video 1 A 35-mm laterally spreading tumor partially infiltrated the interior portion of the diverticular orifice in the ascending colon. Glycerol and hyaluronate solution were injected into the submucosa to maintain adequate mucosal elevation. Mucosal incision and submucosal dissection were performed using a DualKnife and insulation-tipped knife from the anal side; however, safe submucosal dissection was challenging with these knives because of severe fibrosis and abundant blood vessels in the diverticulum. Therefore, to improve the visibility of the submucosa, a scissor-type knife and a multiloop traction device was used to facilitate the submucosal dissection. Finally, en bloc resection was achieved in 117 minutes without adverse events. A part of the diverticular defect after endoscopic submucosal dissection was clipped to prevent delayed perforation.

Spray coagulation reduces the use of hemostatic forceps for intraoperative bleeding in gastric endoscopic submucosal dissection.

Project description:AimsDuring intraoperative bleeding in endoscopic submucosal dissection (ESD), switching to spray coagulation may be beneficial compared with the continuous use of swift coagulation and can reduce the need for hemostatic forceps. We retrospectively assessed the effectiveness of spray modes on intraoperative bleeding during gastric ESD.Methods and resultsA total of 316 bleeding events (156 in the Swift group and 160 in the Spray group) were consecutively recorded. In the Swift group, hemostasis was performed using the swift mode with a retracted tip of the needle-type knife, followed by the hemostatic forceps. In the Spray group, bleeding was treated in a stepwise manner: the swift mode, the spray mode, and the hemostatic forceps. All bleeding events were assigned to one of two groups by an endoscopist who retrospectively reviewed the videos. We compared the use of hemostatic forceps, the total hemostatic time, and the cumulative hemostasis rate between the two groups.The use of hemostatic forceps was significantly lower in the Spray group than in the Swift group (32.7% vs. 13.8%, P < 0.001). There was no significant difference in the total hemostatic time (Swift group, 20 s.; Spray group, 16 s.; P = 0.42), whereas the cumulative hemostasis rate with the knife was significantly higher in the Spray group (P = 0.007).ConclusionThe results suggested that spray coagulation from the tip of the needle-type knife could reduce the use of hemostatic forceps. In gastric ESD, spray coagulation may facilitate the hemostasis of intraoperative bleeding.

Project description:Video 1Patient with a history of gastric ectopic pancreas and epigastric pain. We illustrate the endoscopic submucosal dissection of the ectopic pancreas using a new traction device, the ProdiGi traction wire. Using this device, we were able to resect the lesion en bloc with no adverse events.
