However, some endoscopists are concerned about the potential risk of adverse events. Bile peritonitis due to bile leakage through the fistula is one of the possible adverse events following EUS\u2010HGS. Recently, a novel laser\u2010cut type partially covered self\u2010expandable metal stent (PCSEMS), which is a dedicated stent for EUS\u2010HGS, has become available. This stent has an uncovered part, despite it being a laser\u2010cut type stent, along with a flared end. In addition, it uses a 7\u2010Fr stent delivery. Therefore, tract dilation might not be needed to deploy the stent, which might reduce the incidence of stent migration. In this study, the safety of EUS\u2010HGS using this novel laser\u2010cut type PCSEMS was evaluated by assessing technical success, which was defined as successful stent deployment, and clinical success, which was defined as reduction in serum total bilirubin levels by 50% and resolution of symptoms related to biliary tract obstruction within 2\u00a0weeks. Five patients with unresectable malignant biliary obstruction underwent EUS\u2010HGS using the novel stent. Stent deployment was successfully performed without tract dilation in four patients, although tract dilation using a balloon catheter was needed in one patient. Clinical success was obtained in all patients, and adverse events including abdominal pain and bile peritonitis were not observed in any of the patients. EUS\u2010HGS without tract dilation can be safely performed using a novel laser\u2010cut type PCSEMS. A prospective comparative study evaluating this stent versus conventional stents is needed to corroborate our results.<\/jats:p>","DOI":"10.1111\/den.14077","type":"journal-article","created":{"date-parts":[[2021,7,28]],"date-time":"2021-07-28T09:01:27Z","timestamp":1627462887000},"page":"1188-1193","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Endoscopic
