title: Endoscopic marking clip with an IC tag and receiving antenna to detect localization during laparoscopic surgery.
abstract: Conventional tattooing using India ink for preoperative marking during colonoscopy has been widely used. However, the ink used in this method can spread into the abdominal cavity and induce peritonitis. Therefore, we developed a new marking method using an endoscopic clip with an integrated circuit (IC) tag to accurately identify an objective location. We applied the novel method in laparoscopic surgery using a porcine model and also evaluated it with resected human gastrointestinal tissue.
  
  
  
  We placed an endoscopic clip with an IC tag through a forceps aperture in the gastrointestinal tract, by using a porcine surgery model. After the endoscopic procedure, we performed laparoscopic surgery and approached the receiving antenna in the abdominal cavity to detect the IC tag through the porcine intestine. In an ex vivo examination with human colon tissues, the clip with the IC tag was placed on the mucosal surface to determine its ability to be detected. The receiving antenna near the serosal side of the human colon segment accurately detected the clip with the IC tag.
  
  
  
  We detected the clip with an IC tag with a detection device, by using a laparoscopic surgery model in vivo. We also confirmed its usefulness in five of five (100 %) human colon tissue samples tested ex vivo.
  
  
  
  We developed a novel marking device using an IC tag to identify an objective location. We successfully demonstrated the usefulness of the clip with the IC tag and the antenna device used for its detection in a porcin laparoscopic surgery model and in resected human colon tissue.
