Novel use of a percutaneous endoscopic gastrostomy tube fastener for securing silicone tracheal stents in patients with benign proximal airway obstruction

J Bronchology Interv Pulmonol. 2012 Apr;19(2):121-5. doi: 10.1097/LBR.0b013e318251e238.


Background: Benign tracheal obstruction occurs for a variety of reasons. Bronchoscopic intervention includes silicone stent placement, which effectively maintains airway patency. Stent migration is a common complication, particularly when placed in the proximal trachea. We used a novel technique of securing tracheal stents with a percutaneous endoscopic gastrostomy tube fastener (PEG-TF) to prevent stent migration. The purpose of this study was to determine the feasibility of securing silicone stents in the proximal trachea with PEG-TF.

Methods: Silicone stents were placed under general anesthesia by rigid bronchoscopy in 7 consecutive patients with inoperable benign proximal tracheal obstruction. PEG-TFs were placed under sterile conditions with direct bronchoscopic visualization. A needle was inserted through the anterior neck and silicone stent wall allowing stylet introduction of a T-fastener into the interior of the stent. The T-fastener was secured externally by a metal clamp and cotton pledget at the surface of the neck. Patients had routine outpatient follow-up and covered the external portion of the PEG-TF with a waterproof dressing when showering.

Results: All 7 PEG-TFs were placed without complications. The PEG-TFs were left in for 1 to 25 weeks. Complications of the PEG-TF included localized cellulitis and suture breakage. No stent migration occurred while the fastener was in place. Two stents were removed within 2 weeks due to patient's difficulty tolerating the stent.

Conclusions: Securing silicone stents in the proximal trachea is feasible and may prevent stent migration, but further study and possible modification of the PEG-TF device are needed.
