Summary
Anterior cervical spine surgery (ACSS) can lead to pharyngoesophageal diverticula, a type of traction diverticulum. Surgical management is recommended for these rare, scar-tissue-related esophageal complications.
Area of Science:
- Otolaryngology
- Neurosurgery
- Gastroenterology
Background:
- Pharyngoesophageal diverticula are rare complications following anterior cervical spine surgery (ACSS).
- These diverticula are thought to be traction diverticula, caused by scar tissue formation after surgery.
Observation:
- Three patients with ACSS-related pharyngoesophageal diverticula were identified (2008-2020).
- Patients presented with symptoms related to esophageal obstruction.
- One patient experienced recurrent diverticulum formation despite surgical intervention.
Findings:
- ACSS-related diverticula appear to be traction diverticula, caused by scar tissue formation.
- Dense scar tissue adheres the pharyngoesophageal mucosa to the anterior cervical spine hardware.
- These differ pathologically from Zenker's diverticulum.
Implications:
- Early recognition and aggressive surgical management are essential for ACSS-related pharyngoesophageal diverticula.
- This condition requires a distinct approach compared to other esophageal diverticula.
- Further research into preventative strategies may be warranted.
