Polyglycolic acid (PGA) sheets with fibrin glue are reportedly effective in preventing
post-procedural bleeding in gastric endoscopic submucosal dissection (ESD) [1]
[2]
[3]
[4]. However, it is challenging to deliver and place the PGA sheet over the target ulcer
in the correct position as the sheet is easily crumpled.
We have developed an innovative and reliable delivery method by sewing the circumferential
margin of the PGA sheet with a polydioxanone suture (suture size 0), which creates
tension and prevents the PGA sheet from crumpling during delivery ([Fig. 1]; [Video 1]). An important step is that the start and end points of the suture must intersect
in order to secure it ([Fig. 1 a]). The polydioxanone suture is not only absorbable but also thick enough to create
sufficient tension.

suture (needle length 36 mm, suture size 0).
Video 1 A novel method is demonstrated to deliver a polyglycolic acid sheet to a postendoscopic
submucosal dissection ulcer without crumpling on passage through the esophagus and
overtube.
An 81-year-old man was referred to our hospital for ESD treatment of a 20-mm early
gastric neoplasm in the mid-body of the stomach ([Fig. 2 a]). The lesion was successfully resected ([Fig. 2 b, c]), resulting in a 40-mm post-ESD ulcer. A PGA sheet equipped with a polydioxanone
suture that had been prepared as described above was applied to the ulcer. Forceps
were used to grasp the point of suture intersection. As a result, the shape of the
PGA sheet was maintained, even as it passed through the overtube and esophagus, and
the sheet was delivered and placed in the correct position within 2 minutes ([Fig. 2 d, e]). A second-look endoscopy performed on the day after the ESD showed that the PGA
sheet had remained in place ([Fig. 2 f]). The patient was discharged without any complications.

The PGA sheet equipped with a polydioxanone suture is a simple and reliable method
that can be applied to any ulcer size to increase the success rate and efficiency
of PGA sheet placement.
