Application and usefulness of a new eight‐wire basket catheter for endoscopic extraction of small common bile duct stones: A retrospective multicenter study
Abstract Objectives Distally located small common bile duct stones are often difficult to treat or grasp endoscopically.

| Summary: | Abstract Objectives Distally located small common bile duct stones are often difficult to treat or grasp endoscopically. Therefore, multiple devices, such as baskets or balloon catheters, are frequently used in such cases. However, it is desirable to use a single device for stone extraction from the perspective of cost‐effectiveness. In this multicenter study, we evaluated the efficacy of a new eight‐wire basket catheter for extracting small (≤10 mm) common bile duct stones. Methods We retrospectively analyzed the records of 144 patients who underwent stone extraction using the eight‐wire basket catheter for common bile duct stones ≤10 mm. The success rate of complete stone extraction and the risk factors for the difficulty in stone extraction with the eight‐wire catheter alone were mainly evaluated. Results The success rate of stone extraction with the eight‐wire catheter alone was 86.1%. The final rate of complete stone extraction was 98.0%. The mean of the maximum diameter of the common bile duct and the largest stone dimension were 10.5 ± 3.5, and 5.1 ± 2.1 mm, respectively. Common bile duct diameter ≥12 mm and stone diameter ≥6 mm were identified as independent risk factors for the difficulty in stone extraction with the eight‐wire catheter alone. Conclusions The success rate of the new eight‐wire basket for small common bile duct stone extraction was acceptable. The device is beneficial and could be used from the start for the extraction of small stones < 6 mm. |
