Diagnosis and management of pharyngoesophageal stenosis: A comprehensive approach to prophylactic, endoscopic, and reconstructive treatment options

BACKGROUND

Pharyngoesophageal stenosis (PES) is a serious complication that substantially impacts functional outcomes and quality of life (QOL) for up to a third of head and neck cancer patients who undergo radiotherapy. Dysphagia is often multifactorial in nature and is a devastating complication of treatment that impacts patients' QOL, general health and overall wellbeing. The authors detail the clinical presentation, risk factors, imaging characteristics, preventive measures, and multimodality treatment options for PES.

METHODS

The authors present a comprehensive management algorithm for PES, including treatment by dilation, stenting, spray cryotherapy and dilation, and reconstructive treatment options utilizing different pedicled and free flaps.

RESULTS

The authors advocate for a thorough assessment of the extent and degree of pharyngoesophageal involvement of PES to determine the optimal management strategy.

CONCLUSIONS

The development of post treatment dysphagia requires appropriate imaging and biopsy, when indicated, to rule out the presence of persistent/recurrent cancer. Multidisciplinary management by a team of physicians well-versed in the range of diagnostic and therapeutic interventions available for PES is critical to its successful management.

The Sternocleidomastoid Myocutaneous Flap: A Laryngeal Preservation Option for Total Hypopharyngoesophageal Stenosis

Complete hypopharyngoesophageal (HPE) stenosis is rare and a challenging condition to treat. When endoscopic therapy fails, total laryngectomy with or without pharyngeal reconstruction is usually performed. We present a retrospective case series involving 3 patients with complete HPE stenosis who failed endoscopic repair and were gastrostomy dependent. All were managed successfully with the sternocleidomastoid myocutaneous (SCM) flap. A temporary fistula occurred in 1 patient. Hospitalization ranged from 5 to 15 days, patients resumed oral intake from 21 to 82 days postoperatively, and their gastrostomy tubes were removed from 28 to 165 days postoperatively. We suggest that the SCM flap is a laryngeal preservation option for reconstruction of complete HPE stenosis when endoscopic techniques fail. This flap allows HPE repair and reconstruction within the same surgical field, imposes no significant donor site morbidity, and affords good functional and cosmetic outcomes.
