Brief summary

The purpose of this study is to determine what effect intraoperative topical steroids have on reducing swallowing difficulty following Anterior Cervical Discectomy and Fusion surgery.

Detailed description

Background: Dysphagia is a serious post-operative concern in patients following anterior cervical surgery. Although many experts have acknowledged that dysphagia is often incompletely understood and defined, there is a significant amount of literature to support the significance of this clinical entity. This is the first randomized study to examine the use of topical steroids for the prevention of dysphagia postoperatively after anterior cervical discectomy and fusion. Study Design: This study is a single site, double blinded randomized control trial. All individuals undergoing 2-4 level ACDF that meet the inclusion criteria will be randomized to either: 1. treatment arm or 2. control arm. Both arms will undergo their planned surgeries and will receive the exact same procedure and standard of care as if they were not enrolled in a study. The only difference is that the treatment arm will receive 40 mg of Methylprednisolone Acetate delivered with one Hemostatic Matrix Kit injectable delivery vehicle prior to closure in the prevertebral soft tissues. The control group will receive only Hemostatic Matrix Kit prior to closure in the prevertebral soft tissues. Outcomes: Patients will be asked to fill out questionnaires that assess dysphagia, general swallowing difficulty, and how neck pain impacts their quality of life. Additionally Radiographic images will be obtained at set time points to evaluate soft tissue inflammation and bony fusion.

Interventions

Methylprednisolone Acetate is a corticosteroid known to reduce swelling and inflammation.

OTHERHemostatic Matrix Kit

Hemostatic Matrix Kits help prevent uncontrollable bleeding in a operative site during a procedure.

A summated EAT-10 total score ranges from 0 to 40, with a score ≥ 3 indicative of OD. Modified Eat-10 : Eat-10 questionnaire without questions 1 (My swallowing problem has caused me to lose weight) and 2 (My swallowing problem interferes with my ability to go out for meals) to be applicable during hospitalization. Eat-10 interpretation: Score ranging from 0 to 40 (best-worst) * each question response is 0-4, 0=no problem and 4=severe problem; score is a summation of each question's response Modified EAT-10 interpretation: Score ranging from 0 to 32 (best-worst) * each question response is 0-4, 0=no problem and 4=severe problem; score is a summation of each question's response

Change in Pre-vertebral Soft Tissue Swelling Over 1 YearPre-Op, Post-Op Day 1, Week 4-6, 3 Months, 6 Months, 12 MonthsWe are unable to report this outcome measure because soft tissue swelling was not assessed. The PI deemed it would not be included for this study as there is not a clinical or research standard to do so, nor is there normative data over time to compare against. Thus, data were not collected.
Fusion Rate12 Months1. Flex-Ex X-rays 2. Bony bridging on a CT scan 3. Obvious bony remodeling on lateral X-ray
Adverse Event12 monthAdverse Event (AE) following surgical treatment. Adverse event were classified by severity based on the AO-ISSG criteria and treatment required: Mild: Observed, medication, consult, X-ray. Essentially any management that was quick and easy and could be done at bedside Moderate: ICU admission, re-intubation, complication that had a documented prolonged hospital stay, medical procedure (such as flexible endoscopy), re-presentation to ED Severe: Inpatient re-admission, return to OR for any reason, mortality, failed OR. AE were also categorize as Surgery-site related or unrelated adverse event. Finally, AE were also categorize as potentially related to steroid use (example: leukocytosis, pseudoarthrosis, or wound complications)

Adverse Event

Adverse Event (AE) following surgical treatment. Adverse event were classified by severity based on the AO-ISSG criteria and treatment required: Mild: Observed, medication, consult, X-ray. Essentially any management that was quick and easy and could be done at bedside Moderate: ICU admission, re-intubation, complication that had a documented prolonged hospital stay, medical procedure (such as flexible endoscopy), re-presentation to ED Severe: Inpatient re-admission, return to OR for any reason, mortality, failed OR. AE were also categorize as Surgery-site related or unrelated adverse event. Finally, AE were also categorize as potentially related to steroid use (example: leukocytosis, pseudoarthrosis, or wound complications)

We are unable to report this outcome measure because soft tissue swelling was not assessed. The PI deemed it would not be included for this study as there is not a clinical or research standard to do so, nor is there normative data over time to compare against. Thus, data were not collected.

Patient Reported Swallowing Difficulty Over 1 Year

The Eating Assessment Tool (EAT-10) is used to screen for self-perceived oropharyngeal dysphagia (OD) in community-dwelling elders. A summated EAT-10 total score ranges from 0 to 40, with a score ≥ 3 indicative of OD. Modified Eat-10 : Eat-10 questionnaire without questions 1 (My swallowing problem has caused me to lose weight) and 2 (My swallowing problem interferes with my ability to go out for meals) to be applicable during hospitalization. Eat-10 interpretation: Score ranging from 0 to 40 (best-worst) * each question response is 0-4, 0=no problem and 4=severe problem; score is a summation of each question's response Modified EAT-10 interpretation: Score ranging from 0 to 32 (best-worst) * each question response is 0-4, 0=no problem and 4=severe problem; score is a summation of each question's response
