Intraoperative localization of XXXX in the early stages using a magnetic marking clip detector system (MMCDS).

@entity5 @entity1 @entity29 @entity14
BACKGROUND: In the laparoscopic surgical treatment of early stage @entity14 , intraoperative @entity5 site identification is often difficult. We developed a novel marking method using a magnetic marking clip and a modified magnetometer system. METHODS: We applied magnetic marking clips at the @entity5 site during preoperative colonoscopy and identified the clip site with a magnetic marking clip detector system (MMCDS) of our design. Eleven @entity1 who underwent laparoscopic colectomy were studied. RESULTS: In a basic ex vivo study, magnetic bodies of more than 300 mT magnetic force were easily detected with a 100% detection ratio. In a clinical study, the marking site was detected in all 11 @entity1 . The mean length between the detected site and clip along the @entity29 was 14.1 mm (SD 5.6). The mean detection time was 2.4 min (SD 0.2). CONCLUSION: MMCDS accurately identifies @entity5 sites. This method may be useful for @entity5 site identification during laparoscopic colectomy.
