Abstract:
Background/Aims:Dilation of the tract before stent deployment is a challenging step in endoscopic ultrasound-guided pancreatic duct drainage (EUS-PDD). In this study, we examined the effectiveness and safety of a novel spiral dilator, Tornus ES (Asahi Intec), for EUS-PDD.
Methods:This was a retrospective, single-arm, observational study at Aichi Cancer Center Hospital. The punctured tract was dilated using a Tornus ES dilator in all EUS-PDD cases. Our primary endpoint was the technical success rate of initial tract dilation. Technical success was defined as successful fistula dilation using a Tornus ES followed by successful stent insertion. Secondary endpoints were procedure times and early adverse events.
Results:A total of 12 patients were included between December 2021 and March 2023. EUS-PDD was performed in 11 patients for post-pancreaticoduodenectomy anastomotic strictures and one patient with pancreatitis with duodenal perforation. The technical success rates of stent insertion and fistula dilation using a Tornus ES dilator was 100%. The median procedure time was 24 minutes. No remarkable adverse events related to the procedure were observed, apart from fever, which occurred in 2 patients.
Conclusions:Tract dilation in EUS-PDD using a Tornus ES is effective and safe.
