Surgical and general complications in 2,961 Japanese patients with cervical spondylotic myelopathy: Comparison of different age groups

Abstract

Abstract:Introduction: Details of surgical and general complications for patients with cervical spondylotic myelopathy (CSM) are still uncertain. The purpose of this study was to describe surgeries and their complications among Japanese patients with CSM. Methods: The Japanese Society for Spine Surgery and Related Research performed a nationwide survey on spine surgery and complications in 2011. Data of patients with 2,961 CSM >40 years old were included. The clinicopathological variables were basic demographic and clinical information, surgical information, and surgical and general complications. To examine the influence of age, variables were compared among three age groups: patients 40-64 (n=1,123), 65-74 (n=966), and ! 75 (n=872) years of age. Results: The study included 1,970 males and 991 females and the mean age was 64.3 years old. There were 168 anterior (5.7%) and 2,770 posterior (94.2%) approach surgeries. The vast majority of patients with CSM were treated using the posterior approach, 89.4% of whom had decompression surgery only. Anterior surgeries were more common in the younger age group, but posterior surgeries were equally distributed. The incidence of total complications including surgical/general complications was similar for the anterior (16/168; 9.5%) and posterior (295/2,770; 10.6%) approaches. No patient died on the operating table, but four patients (0.1%) died within one month after surgery. No association was detected between complications and age, comorbidity, and other surgical factors. The incidence of complications was similar for the different age groups. However general complications were predominantly observed in the older group and those who had instrumented surgery. Conclusions: The results indicate that the indication and surgical performance for patients with CSM is favorable in Japan, despite the super-aging population. Few serious complications were reported in this study. However, more detailed informed consent about surgical and, in particular, general complications is necessary for the older patients with CSM.

Serum oxidative stress influences neurological recovery after surgery to treat acutely worsening symptoms of compression myelopathy: a cross-sectional human study

“…Acutely worsening symptoms of compression myelopathy result in severe neurological deficits with poor functional recovery [2]. To date, early surgical treatment is recommended as the only valid therapy for compression myelopathy, and the surgical outcome is relatively favorable [3]. However, in some cases, sufficient improvement in neurological function is not achieved [4].…”

Delayed surgical site infection after posterior cervical instrumented surgery in a patient with atopic dermatitis: a case report

“…Surgical site infection after spinal fusion surgery is a relatively common complication 12 , 13 ) . Once surgical site infection occurs following instrumented spinal surgery, it requires long-term antibiotic coverage, prolonged hospital stays, and multiple surgeries for debridement or drainage.…”

Postoperative neck symptoms of posterior approach for cervical compressive myelopathy: Expansive open-door laminoplasty vs. segmental partial laminectomy

“…However, selecting which procedure to employ remains controversial. Generally, anterior surgeries are performed if myelopathy is present at one or two compressive segments of the spinal cord, while posterior surgeries, such as laminoplasty, are performed regardless of the number of compressive segments 10,11) . Regarding a case in which anterior OPLL occupies more than 60% of the spinal canal, an increasing number of reports have demonstrated better outcomes of anterior procedures than posterior procedures.…”

“…There are various operation procedures and a surgical strategy should be selected according to individual patient condition and needs 12 -16) . Laminoplasty is the most commonly performed posterior procedure 11) . Numerous laminoplasty procedures have been developed for the treatment of cervical compressive myelopathy.…”
