Use of a detachable snare with polyglycolic acid sheets in a simple and novel shielding method for post-endoscopic submucosal dissection ulcers
Many reports have described a shielding method involving the use of polyglycolic acid (PGA) sheets and fibrin glue as a means to prevent post-endoscopic submucosal dissection (ESD) complications [1] [2] [3] [4] [5]. During this procedure, however, a PGA sheet under little tension easily shrinks when exposed to mucus. Therefore, appropriate PGA sheet delivery is required to keep the sheet dry and maintain its shape.
We demonstrate a simple and novel shielding method with autologous fibrin glue and a PGA sheet ([Video 1]). We performed gastric ESD for a 20-mm lesion at the lesser curvature of the body. The size of post-ESD ulcer was 40 × 30 mm ([Fig. 1]). The equipment used consisted of a PGA sheet (NV-M-015G; Gunze, Kyoto, Japan) and a detachable snare (HX-400U-30; Olympus, Tokyo, Japan) ([Fig. 2 a]). First, a PGA sheet was cut to the size of the endoscopic detachable snare (65 × 40 mm) and four points on the PGA sheet were connected to the snare using silk thread ([Fig. 2 b]). The sheet was captured by an endoscopic clip (ROCC-D-26-235-C; Micro-Tech, Nanjing, China) and anchored using clips around the sides of the gastric floor. This method resulted in the ulcer being fully covered by a single PGA sheet ([Fig. 3 a]). The fixed PGA sheet then had autologous fibrinogen and thrombin sprayed onto it simultaneously to bond it. The procedure time was 5 minutes. Follow-up endoscopy the day after the ESD showed full coverage of the ulcer by the PGA sheet ([Fig. 3 b]).
Video 1 A single polyglycolic acid (PGA) sheet of 65 × 40 mm is easily and quickly applied to a post-endoscopic submucosal dissection ulcer using a detachable snare.

In this method, the detachable snare prevents the sheet from shrinking, even when it comes into contact with mucus. Moreover, this novel shielding method is a more rapid procedure because it allows a large size sheet (65 mm) to be applied in one go. In our study, we found that, using this method, a large PGA sheet can be easily applied to a post-ESD ulcer in a short time.
