“…It is an acquired pouch which is located proximally to the upper esophageal sphincter, usually on the posterior hypopharyngeal wall [4]. Pharyngoesophageal diverticulum is mostly found among elderly people who are in their 70s or 80s, and only a few authors have reported it as a much rarer complication of anterior spine surgery [5][6][7][8][9][10].…”

Pharyngoesophageal diverticulum: a delayed complication of anterior cervical spine surgery

et al. 2010

View full text Add to dashboard Cite

Pharyngoesophageal diverticulum after anterior cervical spine surgery is a rarely reported but potentially life-threatening complication. A case report of pharyngoesophageal diverticulum 7 years after anterior cervical spine surgery is presented. The patient suffered from dysphagia, odynophagia, recurrent fever, weight loss, and also an impressive bulging in the neck with swallowing. After careful examination and preparation, he underwent revision surgery via an open procedure, had the implants removed, pouch excised, and esophagus reconstructed reinforced by a sternohyoid muscle flap as well as an omohyoid muscle flap. The post-operative period was uneventful, and he experienced a satisfactory recovery. At last follow up, 2.5 years post surgery, the patient remained symptom free. Upon review of the literature, only six such previous reports with seven cases were found. Diagnostic tools, possible mechanism, correlative factors and treatment are discussed. This patient was fortunate that although his symptoms developed long after the initial anterior cervical operation and the pouch grew impressively large almost perforating, he still recovered well. It again proves the necessity of long-term X-ray follow up, and also reminds the surgeons to be alert of the possibility of esophageal injury even when the esophageal symptoms are mild and occur long after the initial operation.

Late prevertebral abscess with sinus following anterior cervical corpectomy and fusion

et al. 2015

Anterior cervical discectomy/corpectomy and fusion is performed in degenerative, traumatic and neoplastic etiologies of the cervical spine. This procedure is highly successful and associated with fewer complications. The rates of early and late postoperative infection have been reported to be between 0.1% and 1.6%, the late infections are being very rare. We report a rare case of a 30-year-old HIV negative, non-diabetic male who developed a late prevertebral cervical abscess with discharging sinus over posterior triangle of neck 3 years after an anterior cervical C6 corpectomy with fibular grafting and buttress screw fixation performed elsewhere for traumatic fracture C6 vertebra. The abscess was drained using radical neck dissection approach with complete excision of sinus track and removal of the infected implant. On culture, the organism was found to be beta-hemolytic streptococci, for which appropriate antibiotics were administered postoperatively. The sinus tract completely healed in 3 months time. Late infection as a complication of anterior cervical spine surgeries is rare and is associated with esophageal perforation, implant migration, seeding of the deep prevertebral space with oropharyngeal flora, or from surgical site/bacteremia or with Zenker's diverticulum. Few cases have been reported till date, but none have presented with a sinus tract. We present a case of delayed prevertebral abscess after cervical spine instrumentation that followed abnormal path causing sinus track to be developed in the site (the posterior triangle of the neck) other than previous incision site. Exploring both triangles of the neck using radical neck dissection approach was essential for complete excision of sinus track, removal of screw and debridement.

“…Ba, Allis, and Sood identified the physical findings of a pharyngeal diverticulum after ACDF to be dense scar tissue and adhesions in the prevertebral fascia around the diverticula [2, 5, 8]. This delayed esophageal injury following ACDF is often attributed to erosion from a screw migrating and piercing the pharynx.…”

We present a rare complication of endoscopic staple repair of a pharyngeal diverticulum related to prior anterior cervical spine surgery. A 70-year-old male developed a symptomatic pharyngeal diverticulum 2 years after an anterior cervical fusion that was repaired via endoscopic stapler-assisted diverticulectomy. He initially had improvement of his symptoms after the stapler-assisted approach. Three years later, the patient presented with dysphagia and was found to have erosion of the cervical hardware into the pharyngeal lumen at the site of the prior repair. We present the first reported case of late hardware erosion into a pharyngeal diverticulum after endoscopic stapler repair.
