One magnet was inserted through a percutaneous transhepatic biliary drainage pathway, while the other was advanced through an alternative route. After magnet approximation and recanalization, an internal catheter or fully covered self-expandable metal stent (FCSEMS) was placed across the newly formed tract for about 6 months. Patients were followed for a median of 75.2 months to assess complications and BBS recurrence.<\/jats:p>\n                  <jats:p>Of 113 patients who underwent MCA, technical success was achieved in 106 (93.8%) and clinical success in 105 (92.9%). One patient developed mild MCA-related cholangitis, which improved with conservative management. No MCA-related mortality or other major complications occurred. During follow-up, 14.3% had recurrence at a median of 23.7 months (range 3.3\u201364.9) after catheter or stent removal. No patients required surgical intervention during the study period.
