CPT® Code 43510

The procedure described by CPT® Code 43510 is known as gastrotomy with esophageal dilation and insertion of a permanent intraluminal tube, such as a Celestin or Mousseaux-Barbin tube. This surgical intervention is primarily indicated for patients suffering from advanced esophageal cancer, particularly in cases where traditional methods, such as transoral endoscopic approaches, have failed to pass a tube through the esophagus. The procedure involves making an incision in the abdomen to access the stomach, which is then incised to facilitate the dilation of the esophagus. A balloon catheter is introduced to the site of the esophageal stenosis, where it is inflated to widen the narrowed segment. This inflation process may be repeated multiple times to achieve the desired diameter of dilation. Alternatively, a series of progressively larger tubes can be inserted through the stomach to the affected area to achieve the necessary dilation. Once the esophagus has been adequately dilated, a permanent intraluminal tube is placed to ensure the esophagus remains open and functional. Finally, the stomach incision is closed, followed by the closure of the abdominal incision in layers, ensuring proper healing and recovery.
