Core Tip

Core Tip: We used magnetic compression anastomosis (MCA) technology to reconstruct the esophagus. The anastomosis time of the MCA group was shorter than that of the hand-sewn group (7.5 ± 1.0 min vs 12.5 ± 1.8 min, P < 0.01). One month after the surgeries, the mean weight of the dogs in the hand-sewn group had decreased more than that of the dogs in the MCA group (11.63 ± 0.71 kg vs 12.73 ± 0.80 kg, P < 0.05). At 3 mo and 6 mo after the operation, the dogs’ weights were similar between the two groups. MCA is an effective and safe method for esophageal reconstruction. This study shows that MCA technology may be applied to human esophageal reconstruction, provided these favorable results are confirmed by more publications.
