Surgery is the main treatment modality with high morbidity and mortality. Recently, the magnetic compression anastomosis (MCA) technique was employed in such cases with low complication rates. Aims To evaluate the effectiveness of the MCA in completely obstructed BBS. Methods 21 MCA procedures were performed in 19 patients with completely obstructed BBS. All patients had percutaneous biliary access. Magnets were located to the proximal side of the obstruction via percutaneous biliary sheath and the distal side endoscopically. The procedure was terminated as the magnets attracted. Either self-expandable fully covered metallic stent and/or a growing number of plastic stents were introduced after recanalization was achieved. Result A total number of 19 patients with completely obstructed BBS resulting from cholecystectomy or liver transplant underwent 21 MCA procedures. Among those, 19 (90.5%) interventions were successful. The median stricture length that had been measured after magnet attraction was 4 mm (range 1-10 mm). The median magnet coupling time in successful cases was 9 days (range 4-27 days). No correlation was found between magnet coupling time and stricture length (p = 0.27). Complications were observed in 6 (cholangitis:1, magnet migration:2, magnet entrapment:3) of 19 successful MCA procedures. Fifteen of the 19 successful procedures had at least a period of stent-free follow-up. Recurrence of stenosis occurred in 7 procedures, of which 4 remained stent-free with retreatment. Eventually, 12 procedures had stent-free last status. Conclusions MCA is an effective and safe treatment option in completely obstructed BBS. Further studies are required for procedural standardization.en10.1007/s10620-022-07381-3info:eu-repo/semantics/closedAccessBiliary Tract Diseases; Magnets; Extrahepatic Biliary Stasis; Surgical Anastomosis; CholestasisBile-Duct Stenosis; Liver-Transplantation; Current Diagnosis; ManagementArticle671049064918350504302-s2.0-85123120335WOS:000744857400001Q1Q3
