The 'penny pincher': a new technique for fast and safe removal of esophageal coins

Considerable debate surrounds the choice of technique for the removal of esophageal coins: endoscopic extraction versus dislodgement with a Foley balloon versus dislodgement using bougienage. The "penny-pincher" (PP) technique was developed as an alternative, incorporating the main advantages of these various approaches.

The PP technique is based on the insertion of a fluoroscopically guided device that consists of a grasping endoscopic forceps covered by a soft rubber catheter. The forceps provides a firm hold on the coin. The catheter protects the oropharynx and aligns the device with the coin. Once the tip of the catheter is close to the upper edge of the coin, the previously retracted radiopaque prongs of the grasping forceps are deployed and the edge of the coin firmly grasped and extracted. The procedure is done without anesthesia or sedation.

Twenty coins were removed from 19 consecutive children with a mean age of 34 months. Average lip-to-lip removal (including fluoroscopy) time was 41 seconds. There were no complications, and all patients were discharged shortly after coin removal.

The penny-pincher method for the removal of upper esophageal coins combines the simplicity, speed, and cost effectiveness of balloon catheter or bougie coin dislodgement with the safety and secure grasping of endoscopic or forceps removal.
