ASGE DDW Videos from Around the World | 2025-MAGNETIC BEAD EMBEDDED IN THE ABDOMINAL CAVITY SUCCESSFULLY RETRIEVED BY ENDOSCOPY

Video Transcription

I am Dr. Li from Guangdong Province People's Hospital. I will present this video titled  Magnetic Beat Embedded in the Abdominal Cavity  Successfully Retrieved by Endoscopy.  A two-year-old boy experienced appetite loss  accompanied by recurrent coughing and  expectoration for one year.  Abdominal radiography disclosed a circular, bead-like, high-density shadow in the upper abdominal region.  Eleven magnetic beads were successfully extracted via gastroscopy in local hospital.  Abdominal x-ray later reviewed one remained in a fixed position. This boy underwent a  gastroscopy in our hospital revealing a scar on the lesser curvature of the  antrium without any foreign body visible within the stomach.  Subsequent endoscopic  ultrasound identified a strong  echoic image outside the gastric wall at the side of the  anterial scar.  Firstly, we used a dual knife to mark the scar of the gastric anterium.  After the  submucosal injection was completed, the circular pre-incision was  completed along the marker point and  the submucosal section was gradually performed.  The scar is obvious here.  After entering the  submucosa, the position of the magnetic beads is difficult to confirm.  Therefore, we use a homemade guidance device to locate the magnetic beads and  then continue to cut the scar tissue at the location.  After the magnetic beads are exposed, the surrounding tissue is stripped along the magnetic beads.  And finally, the magnetic beads are removed using an endoscopic retrieval extractor.  After removal, the wound did not break through the serosal layer into the abdominal cavity. So we used titanium clips to seal the wound.  This is the magnetic beads and a small magnetic was embedded into an endoscopic retrieval net and introduced into the cavity for bead location.  Post-operative x-ray showed no perforation and residual magnetic beads. One month after operation, gastroscopy showed that the wound healed well.  To our knowledge, this is the first case of magnetic beads embedded in the abdominal cavity of infant, which was successfully retrieved only with endoscopy.  This innovative magnetic guidance device could provide accurate location and endoscopic full thickness resection provide a minimally invasive alternative in such circumstances.

Video Summary

Dr. Li, from Guangdong Province People's Hospital, presents a case where a two-year-old boy, who experienced appetite loss and coughing, had a bead-like shadow found in his abdomen. Eleven magnetic beads were initially removed via gastroscopy, but one remained. At Dr. Li's hospital, endoscopic ultrasound located the bead outside the gastric wall. A dual knife marked the scar, and a homemade guidance device helped locate and remove the bead. The wound was sealed with titanium clips, showing no perforation. This innovative endoscopic approach, being minimally invasive, successfully retrieved the embedded bead in an infant without complications.
