Application of a double-balloon method to remove button battery at the entrance of esophagus in a 17-month-old child: a case report.

Background: Since children have strong desire for exploration and poor safety awareness, foreign body impaction in the digestive tract is one of the most common critical conditions in children. Due to the popularity of electronic products, button battery ingestion by mistake is also increasing in children. Button battery impaction in the esophagus can cause serious complications such as esophageal cauterization and perforation in a short time. Therefore, more active treatment strategies should be taken once button battery ingestion occurs. Surgical treatment is traumatic and prone to cause various complications, so removal of foreign body retained in the esophagus under endoscopy is the preferred strategy.
Case Presentation: We introduced a new method to remove the button battery retained in the esophagus of a 17-month-old child. Soon after the patient arrived at the hospital, we actively arranged endoscopic surgery. After the gastroscope entered the esophageal inlet, we first cleaned up the esophageal residues, and then, the button battery was exposed. The surrounding esophageal mucosa showed a little cauterization-like damage. We tried to remove the foreign body using foreign body forceps first, but failed after repeated attempts. Then, we tried to use a disposable balloon to assist in dragging the foreign body, but because the patient was younger with narrower esophagus and the drag resistance of the foreign body was abnormally large, this method also did not work. Violent dragging may cause tearing and perforation of the esophagus. Hence, we used a columnar balloon to help expand the esophagus and successfully removed the button battery at the entrance of the esophagus. For this new method, the columnar balloon was used to expand the esophagus and the button battery was clamped with foreign body forceps, and then, the foreign body was dragged by a disposable stone removal balloon. Because two types of balloons were used, it was named double-balloon method.
Conclusions: For the foreign body retained in the esophagus of younger children, the double -balloon method is recommended when the foreign body cannot be removed by traditional methods.
