Background Anterior cervical disk fusion (ACDF) is a common surgical approach for the treatment of cervical spine pathology. Esophageal perforations, though uncommon, are a devastating complication of this surgery. The objective of this paper is to assess the success of different treatment approaches for the management of esophageal/pharyngeal injury after ACDF. Methods Given the absence of prospective trials, the review includes institutional case reports and case series from 1985–2020 in the English language literature. Only cases of esophageal/pharyngeal injury in the setting of anterior cervical hardware were considered for study inclusion. For purposes of this study, treatment success is defined as resumption of oral intake. Results The database review identified 76 distinct series that meet criteria for study inclusion, with 173 patients available for analysis. A heterogeneous array of treatments was used for the management of pharyngoesophageal injuries after ACDF ranging from observation to complex free tissue reconstruction, with varying degrees of treatment success reported. We identified a number of factors, specifically duration of injury from initial ACDF procedure, which may impact the complexity of treatment required to maximize likelihood of treatment success. Conclusions Pharyngoesophageal injuries, albeit rare, are a serious and often complex complication after ACDF procedures. We propose a detailed algorithmic approach to guide decision making if faced with this clinical challenge. The huge variability in how these patients are treated emphasizes the potential utility of future multiinstitutional studies.

The rate of cervical spinal fusion has been increasing significantly. However, there is a paucity of literature describing trends based on surgical approach using complete population databases. We investigated the approach-based trends in epidemiology, indications, and in-hospital outcomes of cervical spinal fusion.New York's Statewide Planning and Research Cooperative System database was queried to identify patients who underwent primary subaxial cervical fusion from 1997 to 2012. Demographic and clinical information was obtained. Subgroup analyses were performed based on surgical approach: anterior (A), posterior (P), and circumferential (C).A total of 87,045 cervical fusions were included. Over the study period, the population-adjusted annual fusion rate increased from 23.7 to 50.6 per 100,000 population (P0.001). A fusion was most common (85.2%), followed by P (12.3%), and C (2.5%). Mean ages were 49.8 ± 11.9, 59.9 ± 15.2, and 55.1 ± 14.5 years (P0.001), respectively. Although rates remained steady among younger patients, they increased for older patients. Overall, degenerative conditions were the predominant indications for surgery and increased in rate over time. The mean length of stay was: A, 3.1 ± 10.5; P, 9.1 ± 14.1; and C, 14.1 ± 22.5 days (P0.001). Rates of in-hospital complications were A, 3.0%; P, 10.5%; and C, 18.9% (P0.001), and mortality was A, 0.3%, P, 1.8%, and C, 2.5% (P0.001).The rate of subaxial spinal fusions increased 114% from 1997 to 2012 in New York State. Rates remained stable in younger patients but increased in the older population. Preoperative indications and postoperative courses differed significantly among the various approaches, with patients undergoing anterior fusion having better short-term outcomes.
