New transillumination auxiliary technique for peroral endoscopic myotomy

Double-scope per oral endoscopic myotomy (POEM): a prospective randomized controlled trial

“…Double-scope POEM was performed as above, but with the addition of a second endoscope, similar to the technique described by Baldaque-Silva [19]. Immediately following completion of the myotomy, a 5.4-/5.8-mmdiameter neonatal gastroscope (GIF-XP290N, Olympus, Japan) was introduced into the stomach to obtain a retroflex view of the gastric cardia, while the dissecting scope was placed at the end of the submucosal tunnel and used to transilluminate.…”

“…A final technique, first published by Baldaque-Silva in 2014 [19], utilizes a second endoscope to obtain a retroflexed view of the gastric cardia and determine the extent of submucosal dissection by transillumination. The advantage of this technique is that it can be performed with a standard endoscopy tower and requires only basic endoscopy skills.…”

The East in the West

“…It is expected that the good results of different Portuguese centers in gastric ESD cases will soon lead to the implementation of ESD in esophageal and colorectal superficial lesions. Portugal may be the new frontier in the development of ESD and of other advanced endoscopic techniques in the West [10]. That may be accomplished by a centralization of ESDs in highvolume centers and by a collaboration between different hospitals in order to establish the new standards on ESD in the West and to promote the development of new advanced techniques.…”

Peroral endoscopic myotomy: a literature review and the first UK case series

“…Using transillumination of the paediatric gastroscope in the submucosal tunnel, the extent of the submucosal tunnel on the gastric side of the LOS is confirmed. 20 This was used in four challenging cases because of previous treatment and one with significant fibrosis.…”
