3482 Endoscopic removal of impacted sharp foreign body in esophagus.

Background/Aims: Sharp impacted esophageal foreign bodies can be very difficult to manage. When attempting to remove such objects inappropriately, life threatening complications, such as perforation can occur. Therefore, surgical intervention generally affords a safer approach. The aim of this study is to evaluate the safety and efficacy of endoscopic removal of impacted sharp esophageal foreign bodies using dilation method with oral side balloon. Methods: Total of 17 patients(Male 6, Female 11) with impacted sharp esophageal foreign bodies underwent endoscopic extraction. The following technique was successfully performed at our hospital(Figure A,B). Oral side balloon(Top Co. Japan) for esophageal variceal sclerotherapy was attached on the distal part of endoscope. Under local anesthesia, endoscope was inserted near the proximal part of the esophageal foreign body. Then, oral side balloon was gradually dilated. Dilataion of proximal part of esophagus made it possible to release the impacted sharp foreign body from the esophageal wall. Results: The types of foreign bodies were fish bones(10 case), and press-through packages(7 cases). Endoscopic removal was successful in all 17 cases without complications such as perforation. Conclusion: This method using oral side balloon is safe and effective in removing impacted sharp esophageal foreign bodies avoiding surgery and possible perforation.
