Double incision and snare resection in symptomatic Zenker's diverticulum: a modification of the stag beetle knife technique

Gölder et al.

Fig. 1 Treatment of Zenker's diverticulum using the double incision and snare resection method. a, b A soft diverticuloscope is introduced at the beginning of the procedure to expose the diverticular bridge for further treatment. c, d Double incision on two opposite sides of the cricopharyngeal bar (c left side, d right side incision). e – h Mucosa and muscle fibers in between the double incision are resected with a polypectomy snare. i, j All transvers fibers of the musculus cricopharyngeus are carefully cut through, and a wider opening towards the esophageal lumen could obtained.

Kitagawa et al.

Fig. 5 Endoscopic images of the same intramucosal gastric carcinoma (case #3) showing: a a red depressed lesion (arrow) in the cardia; b magnifying blue-laser imaging; c magnifying linked color imaging with indigo carmine dye, in which an irregular microsurface pattern and irregular microvascular pattern are vividly seen.

Stent-over-sponge (SOS): a novel technique complementing endosponge therapy for foregut leaks and perforations

Valli et al.

Fig. 1 The stent-over-sponge (SOS) treatment, a combination of endosponge and self-expandable metal stent (SEMS), is shown in patient #10. a Computed tomography (CT) scan showing a large abscess cavity before sponge treatment. b – f Endoscopic views showing: b the abscess cavity with a surgical drain in situ; c the intracavitary endosponge before overstenting; d the endosponge tube going into the cavity on the left, with the lumen on the right; e SEMS overstenting with a nasojejunal feeding tube in position; f vital granulation tissue within the cavity after endosponge and SEMS removal.

Underwater endoscopic mucosal resection for superficial nonampullary duodenal adenomas

Yamasaki et al.

Fig. 1 Underwater endoscopic mucosal resection (UEMR) for a duodenal adenoma of 8mm. a Upper gastrointestinal endoscopy showed a slightly elevated lesion, 8mm in size, in the second portion of the duodenum. b A Captivator II snare was opened above the lesion. c The mucosal defect after UEMR. d Complete closure with endoclips.
