“…With the continuous progress of medical technology, the "minimally invasive" and "precision" of surgery have always been the common goal and direction of doctors and patients. 23 Safe and effective labeling methods can help operators operate more accurately. This study aims to explore and verify the application possibility of magnetic materials and magnetic detectors for preoperative labeling of gastric cancer and preliminarily confirm that this method is feasible, effective, and safe.…”

Objective: Preoperative labeling of gastric cancer is an important means to determine the surgical margin. At present, there are many commonly used labeling methods. However, which is more accurate and has fewer complications remains to be studied. Through animal experiments, this study explored the feasibility, accuracy, and safety of a magnetic detector combined with magnetic beads for the preoperative labeling of gastric cancer.Methods: A total of 10 beagle dogs were included in the study. Each dog was randomly labeled with magnetic beads in the gastric body and antrum. After labeling, the magnetic detector was used to explore the gastric serosa surface, and the positioning titanium clip was released at the detected magnetic bead. The main monitoring index was to measure the distance between the labeled magnetic beads and the positioning titanium clamped. The secondary indexes were detection time, magnetic induction intensity, magnetic bead shedding rate, mucosal injury rate, bleeding, and leukocyte and C-reactive protein levels before and 24 hours after the operation.Results: All 10 beagle dogs completed the marking and exploration successfully. The average distance between the magnetic beads and the positioning titanium clip in 20 cases was 5.90 ± 2.36 mm. The average detection time was 1.60 ± 0.69 min, and the average magnetic induction intensity was 3.76 ± 1.11 mT. No magnetic beads were found to fall off, 1 case had a mild mucosal injury, and 2 cases had a small amount of bleeding when releasing the positioning titanium clip. The white blood cells before and 24 hours after the operation were 7.43 ± 0.94(×10 9 /L) versus 7.79 ± 0.67(×10 9 /L) (P = 0.34). The C-reactive protein before and 24 hours after the operation were 5.24 ± 0.97 µg/mL versus 5.95 ± 1.02 µg/mL (P = 0.13). Conclusion:A magnetic detector combined with magnetic beads for gastric cancer labeling is feasible, accurate, and safe. It is expected to be further applied in the clinic.
