A novel self‐assembling hemostatic agent as an effective therapeutic tool for intracavitary bleeding from peripancreatic fluid collection after endoscopic ultrasonography‐guided drainage using a lumen‐apposing metal stent

EUS‐guided drainage using a lumen‐apposing metal stent (LAMS) has demonstrated promising clinical efficacy for peripancreatic fluid collection. However, intracavitary bleeding has been reported after LAMS placement. Yamamoto et al. reported endoscopic hemostasis using hemostatic gel for intracavitary bleeding.
