Combined Anterior Osteophytectomy and Cricopharyngeal Myotomy for Treatment of DISH-Associated Dysphagia

Diffuse Idiopathic Skeletal Hyperostosis (DISH)-Phagia: A Case Report and Review of Literature of a Rare Disease Manifestation

Diffuse idiopathic skeletal hyperostosis (DISH), also called Forestier disease, is a clinical entity characterized by ossification of the anterolateral ligaments of the spine. DISH is more commonly diagnosed in older males, with an estimated prevalence of 42% in patients older than 65 years. As the disease affects predominantly the thoracic spine, dysphagia is a rare presentation of this entity observed in only 0.6-1.0% of the cases. We present a clinical case of an 84-year-old male with complaints of progressive dysphagia and foreign body sensation within one year of evolution. Computed tomography imaging revealed an anterior C4-C5 osteophyte compressing the posterior hypopharyngeal wall. Flexible endoscopy revealed a deformed and stenotic hypopharynx. The patient underwent surgical treatment with anterior cervical osteophyte resection using the Smith-Robinson approach. The patient showed significant improvement in preoperative symptoms, and no recurrence was detected at six months of follow-up. We also aim to discuss the clinical and radiological characteristics of the disease, as well as the crucial steps for a correct diagnosis and treatment of this rare disease.

Diffuse Idiopathic Skeletal Hyperostosis (DISH): Role of Logopedic Rehabilitation in Dysphagia

Forestier's disease is a systemic, degenerative metabolic condition, which is still insufficiently investigated and understood, characterized by the progressive ossification of the ligaments and entheses. This case describes a 63-year-old man admitted to our department after several years of failed attempts to obtain a definitive diagnosis presenting with a painless mass in the pre-auricular region, gradually worsening dysphonia, severe dysphagia relating to solids, stiffness, and mild pain at the back of the neck. After performing further diagnostic tests, in addition to a pleomorphic adenoma, the simultaneous presence of diffuse spondylarthrosis on the cervical spine was highlighted, with beak-like osteophytes at C2-C5 resulting in esophageal compression. Given the absence of upper digestive endoscopy abnormalities, we initiated an intense logopedic and postural rehabilitative treatment, which led to a significant improvement in the patient's dysphagia symptoms. In addition, we limited the use of medical therapy to solely indomethacin in order to control the osteophytic process.

Diffuse idiopathic skeletal hyperostosis of the cervical spine causing dysphagia and airway obstruction: an updated systematic review

BACKGROUND AND CONTEXT

Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by growing ossifications of spinal entheses and tendons, which may cause trachea and esophagus compression when located anteriorly in the cervical spine.

PURPOSE

Our previous systematic review on the epidemiological and clinical knowledge of dysphagia and airway obstruction caused by cervical DISH was updated, with a focus on (surgical) treatment and outcomes.

STUDY DESIGN

A systematic review of the literature was performed.

METHODS

Publications in Medline and EMBASE from July 2010 to June 2021 were searched. Two investigators performed data extraction and study specific quality assessment.

RESULTS

A total of 138 articles (112 case reports and 26 case series) were included, describing 419 patients with dysphagia and/or airway obstruction. The mean age of the patient group was 67.3 years (range: 35-91 years), and 85.4% was male. An evident increase of published cases was observed within the last decade. Surgical treatment was chosen for 66% of patients with the anterolateral approach most commonly used. The total complication rate after surgery was 22.1%, with 12.7% occurring within 1 month after intervention. Improvement of dysphagia was observed in 95.5% of operated patients. After a mean follow-up of 3.7 years (range: 0.4-9.0 years), dysphagia recurred in 12 surgically treated patients (4%), of which five patients had osteophyte regrowth.

CONCLUSIONS

The number of published cases of dysphagia in patients with DISH has doubled in the last decade compared to our previous review. Yet, randomized studies or guidelines on the treatment or prevention on recurrence are lacking. Surgical treatment is effective and has low (major) complication rates. Common trends established across the cases in our study may help improve our understanding and management of dysphagia and airway obstruction in cervical DISH.
