Total neopharyngeal stenosis following pharyngolaryngo-oesophagectomy with gastric interposition: Successful recanalisation using a transcervical radiologically guided technique.

Introduction: Pharyngo-oesophageal stricturing is common following treatment of head and neck cancers. Absolute dysphagia secondary to total stenosis, although rare, is particularly debilitating and presents a significant therapeutic challenge. We present a strategy for managing total neopharyngeal stenosis following pharyngolaryngo-oesophagectomy (PLOG).

Presentation Of Case: A 71-year-old female developed total neopharyngeal stenosis following PLOG with gastric interposition for squamous cell carcinoma of the proximal cervical oesophagus/post-cricoid. A transcervical, percutaneous, radiologically guided procedure was performed to restore lumenal patency, which enabled resumption of oral feeding.

Discussion: Established treatments for pharyngo-oesophageal strictures are frequently limited by complications in patients with complex strictures or total stenoses. Whilst several interventions have been described, recent interest has focussed on combined antegrade/retrograde endoscopic procedures dilating a pre-existing gastrostomy site for access. This was not possible in our patient due to the surgically altered anatomy which posed a unique therapeutic challenge.

Conclusion: This is the first reported percutaneous, transcervical, radiologically guided technique to treat neopharyngeal stenosis following PLOG. It demonstrates a novel and efficacious approach which may be considered in the management of this rare but significant complication.
