Abstract
Background
Intraoperative tumor localization often is difficult during laparoscopic surgery for early-stage upper gastrointestinal tumors.
Method
This study enrolled 15 patients undergoing laparoscopic gastrectomy. A magnetic marking clip–detecting system was used to apply a marking clip to the tumor site during preoperative gastroscopy, and to detect a marking magnetic body.
Results
In a basic ex vivo study, the mean permeance rate on the gastric wall serosal surface was 0.97 ± 0.01. Magnetic flux densities required for exploration were 52.6 mT on the gastric wall serosal surface and 312.4 mT 10 mm away from the surface. In a clinical study, the mean distance between the detected tumor site and the clip along the longitudinal axis was 8.3 ± 3.2 mm. The mean detection time was 5.7 ± 2.3 min.
Conclusion
The magnetic marking clip–detecting system may be useful for tumor site detection during laparoscopic gastrectomy.
