Magnetic compression anastomosis to restore biliary tract continuity after obstruction following major abdominal trauma: A case report

Figure 1 The surgical planning of abdominal sinus-duodenal magnetic compression anastomosis. A: Magnetic resonance cholangiopancreatography; B: Schematic illustration of the placement process of daughter magnet and parent magnet; C: The parent and daughter magnets are in apposition; D: The magnets were expelled and abdominal sinus-duodenal anastomosis was established. DM: Daughter magnet; PM: Parent magnet.

Figure 2 Endoscopic procedure. A: The parent magnet (PM) enters the duodenum; B: The PM is shown in X-ray; C: The daughter magnet (DM) is inserted through the abdominal sinus; D: X-ray shows that the DM is attracted to the PM. DM: Daughter magnet; PM: Parent magnet.

Figure 3 Postoperative abdominal imaging data. A: The state of the magnets one day after the operation; B: The state of the magnets three days after the operation; C: The magnets expelled from the body; D: Biliary stent has been placed at the abdominal sinus-duodenal magnetic anastomosis. DM: Daughter magnet; PM: Parent magnet.
