The slim scope has an outer diameter of 7.9\u200amm, an accessory channel diameter of 3.2\u200amm, and a downward bending angle of 160 degrees.

The median lesion size was 15\u00a0mm (2\u201340\u00a0mm), and the median procedure time was 30 min (5\u2013105 min). Various strategies, including\u00a0multiple tunnels, pocket creation,\u200b and\u00a0endoscopic intermuscular dissection, were employed.<\/jats:p>\n                  <jats:p>The novel slim gastroscope is feasible for endoscopic submucosal dissection\u00a0in many locations including the pharynx and duodenum and in certain complex lesions (large gastric lesions, rectal lesions with deep submucosal invasion, and circumferential esophageal lesions).
