Core Tip

Core Tip: Magnetic compression anastomosis is a minimally invasive technique that creates a new lumen by compressing tissue between paired magnets until a tract forms and matures. The strongest clinical evidence exists for completely obstructed benign biliary strictures in which guidewire passage is not possible. Key determinants of successful outcomes include short stricture length, stable magnet alignment, appropriate compression force, and structured postprocedural calibration with dilation or temporary stenting. Although magnetic compression anastomosis is promising, it currently relies mainly on observational studies, and further prospective research is needed to establish standardized indications and long-term outcomes.
