Outpatient anterior cervical discectomy and fusion for cervical disk disease: a prospective consecutive series of 96 patients.

OBJECTIVES: To evaluate surgical complications and clinical outcome in a consecutive series of 96 patients undergoing anterior cervical discectomy and fusion (ACDF) for cervical disk degeneration (CDD) in an outpatient setting. METHODS: Pre-, per-, and postoperative data on patients undergoing single- or two-level outpatient ACDF at the private Oslofjord Clinic were prospectively collected. RESULTS: This study includes 96 consecutive patients with a mean age of 49.1 years. 36/96 had a two-level ACDF. Mean postoperative observation time before discharge was 350 min, and 95/96 were successfully discharged either to their home or to a hotel on the day of surgery. The surgical mortality was 0%, while the surgical morbidity rate was 5.2%. Two (2.1%) patients developed postoperative hematoma, 2 (2.1%) patients experienced postoperative dysphagia, and 1 (1%) experienced deterioration of neurological function. Radicular pain, neck pain, and headache decreased significantly after surgery. 91% of patients were satisfied with the surgery, according to the NASSQ. CONCLUSION: ACDF in carefully selected patients with CDD appears to be safe in the outpatient setting, provided a sufficient postoperative observation period. The clinical outcome and patient satisfaction of outpatients are comparable to that of inpatients.

Surgical mortality and complications leading to reoperation in 318 consecutive posterior decompressions for cervical spondylotic myelopathy.

OBJECTIVE: To determine surgical mortality, incidence of surgery-related neurological deterioration and incidence of postoperative infection or hematoma requiring reoperation in a consecutive series of 318 patients surgically treated with laminectomy or laminoplasty for cervical spondylotic myelopathy (CSM). MATERIALS AND METHODS: This is a retrospective study of 318 consecutive patients treated with laminectomy or laminoplasty for CSM at Oslo University Hospital in the time period 2003-2008. The defined neurosurgical catchment area for OUS is the southeast region of Norway with 2.7 mill inhabitants. The patient charts were systematically reviewed, focusing primarily on operative notes, postoperative (po) complications, such as po deterioration of neurological function, po hematoma and po infection and neurological function at most recent follow-up. RESULTS: The mean age was 64 years (range 29-90 years). Laminectomy was performed in 310/318 (97.5%) and laminoplasty in 8/318 (2.5%) of the patients. The incidence of laminectomy/laminoplasty for CSM was 2.0/100,000 inhabitants per year. The surgical mortality was 0%, and 37 (11.6%) patients had a deterioration of neurological function in the immediate postoperative period. Four (1.3%) patients were reoperated because of po hematoma. We found a statistically significant association between po hematoma and previous posterior neck surgery and American Association of Anaesthetists (ASA) score. Five (1.6%) patients were reoperated because of postoperative infection. Univariate logistic regression analysis showed a statistically significant association between po infection and the number of levels decompressed. CONCLUSIONS: The incidence of laminectomy/laminoplasty for CSM is 2.0/100,000 inhabitants per year. Surgical mortality, postoperative hematoma and postoperative infection are rare complications of laminectomy/laminoplasty for CSM. Neurological deterioration is not an uncommon complication after posterior decompression for CSM.

Immediate (0-6 h), early (6-72 h) and late (>72 h) complications after anterior cervical discectomy with fusion for cervical disc degeneration; discharge six hours after operation is feasible.

OBJECTIVES: The introduction of minimally invasive techniques and total intravenous anaesthesia has led to reports of the performance of anterior cervical discectomy and fusion as an outpatient. The safety of this approach, requires information about the complications presenting within this period. The aim of this study was to assess the rates and types of immediate (0-6 h), early (6-72 h) and late (>72 h) complications after anterior cervical discectomy with fusion. METHODS: We prospectively studied complications after anterior cervical discectomy with fusion in patients with degenerative cervical disc disease. There were 390 consecutive operations: 278 fused with autologous iliac crest bone graft and 112 with a PEEK (Polyetheretherketone) graft. RESULTS: No patient died. Thirty seven patients (9%) experienced one or more complications that could be related to the operation. These presented in the immediate, early and late periods in 17, 1 and 19 patients, respectively. Thus, 18/37 complications were detected before discharge from the neurosurgical department 48-72 h after operation and of these 17 (4.2%) were detected within the first 6 h after surgery. Each of the five potentially life-threatening neck hematomas was detected within 6 h (immediate). CONCLUSIONS: After anterior cervical discectomy and fusion, a 6 h postoperative observation period followed by discharge from the neurosurgical unit is likely to be as safe as observation as an inpatient for a longer period.
