Lumen Reconstruction Using a Nelaton Catheter as a Mold for Esophageal Constriction and Perforation in a Cat

Abstract

A 6-year-old male neutered domestic cat presented with esophageal obstruction and underwent endoscopic balloon dilation; however, the esophagus was perforated during the procedure. Thoracotomy was performed to enable visualization of the condition of the esophagus. Extensive esophageal stenosis was observed, and it was considered impossible to remove the stenosis and anastomose the esophagus. Therefore, a Nelaton catheter (NC) was passed through the lumen of the stenosis site and was used as a mold to maintain the esophageal lumen, enabling the passage of saliva. The NC was left in place in the esophagus for 3 months while the cat was fed through a gastrostomy tube. After removal of the NC, the cat was able to eat soft food without regurgitation and/or vomiting, and has survived for more than 3 years. The use of a NC to reconstruct the esophageal lumen may be a good option in a cat with life-threatening esophageal constriction.
