Objective Adverse events such as bile leakage and bleeding are among the issues that need to be resolved in EUS-guided choledochoduodenostomy (EUS-CDS). To overcome this problem, we developed a new EUS-CDS technique using a 19-G Franseen needle without tract dilation. This study aimed to evaluate the safety and efficacy of the new EUS-CDS technique.
Methods This single-center retrospective study included 20 consecutive patients who underwent EUS-CDS for primary drainage using a 19-G Franseen needle between March 2020 and May 2023. The primary endpoint was the technical success rate of EUS-CDS without tract dilation.
Results The technical success rate of EUS-CDS was 20/20 (100%). None of the patients required any additional tract dilation, such as by using a balloon or electric cautery. The median procedure time was 7.8 (range, 3.2-19.4) min. No early adverse events were observed.
Conclusion The 19-G Franseen needle appeared to have a sufficient dilatory effect during puncturing. This EUS-CDS technique appears to be safe and effective and has the advantages of no adverse events and it is also a simplified procedure, which suggests its potential for widespread use in primary drainage.
