Perioperative Course
INTRAOPERATIVE COMPLICATIONS
Each patient underwent side-to-side MS DI without intraoperative complications. Initially, the MADS laparoscopic positioning device was used to advance the distal magnet to the ileum, but this maneuver was found to be better accomplished using the traction of a single MS magnet directed by laparoscopic forceps. Following successful pairing of the DI magnets (Fig. Patient radiograph of magnet alignment and fusion in the right upper quadrant, postoperative day 1. Note the presence of marking clips at 250 cm on the magnet sideTotal mean side-to-side MS DI operative time was 138.4 ± 12.4 SEM minutes (median 129.0; min 114.0, max 185.0) including a mean 57.0 ± 15.2 min (median 49.0; 28.0, 115.0) to position the distal magnet at the ligament of Treitz; 60.0 ± 2.7 min (median 59.0; 54.0, 68.0) to direct the magnet to the ileal position; and 13.4 ± 4.7 min (median 10.0; 2.0, 30.0) to appose distal and proximal magnets for fusion. Procedure segment time estimates represent the early operative learning curve and instrumentation. The mean time to magnet expulsion was 58.2 ± 12.5 days.
