[Clinical experience with automated percutaneous diskectomy].

Percutaneous automated aspiration discectomy (Nucleotome, Surgical Dynamics) is a new procedure for treating herniated lumbar discs. In a series of 35 patients, followed-up after 6 months, the overall success rate was 74%. 19 patients resumed work 4 weeks after surgery. In 6 patients the interventions were judged as failures and required reoperation (laminectomies). All the patients obtained complete relief. Meticulous selection of patients for percutaneous lumbar discectomy is the key to success. No intra-operative or post-operative complications occurred.

Percutaneous diskectomy.

Automated percutaneous diskectomy and manual percutaneous diskectomy (PCD) have gained recent popularity as alternatives to traditional surgical diskectomy or microdiskectomy. Initial reports of morbidity seem low. The rates of infection, and neurologic and vascular complications appear comparable or less than the morbidity associated with surgical diskectomy or microdiskectomy. However, inconsistent reports of the efficacy of PCD may cause more concern about overuse than about the morbidity.

A comparison of the effects of automated percutaneous diskectomy and conventional diskectomy on intradiscal pressure, disk geometry, and stiffness.

Diskectomy, chemonucleolysis, percutaneous diskectomy, and laser ablation are used to treat patients with sciatica. The effects of percutaneous diskectomy on the intradiscal pressure of the human disk are not known. Our aims were to determine (a) whether removal of nucleus through automated percutaneous diskectomy significantly reduces intradiscal pressure without altering the disk geometry and stiffness, and if so, how much nucleus removal is required to achieve these goals; and (b) whether the effects of conventional diskectomy on these same parameters are equivalent to removal of nucleus through automated percutaneous diskectomy. Cyclic compressive loads of 20-900 N were applied to lumbar disks. Conventional diskectomy or automated percutaneous diskectomy (performed for 40 min with biomechanical measurements made four times at 10-min intervals) was then performed under zero load and the specimens retested under the same cyclic compressive loading. There were significant (p < 0.01) decreases in intradiscal pressure (by 7% under 900 N) after 10 min of automated percutaneous lumbar diskectomy. There were no further significant decreases in pressure during the next 30 min of percutaneous diskectomy. There were also significant decreases in pressure due to a puncture hole made with the Nucleotome trephine alone, without removal of disk material, and there was no difference in pressure after trephining alone and after percutaneous diskectomy. Decreases in disk height were significant, ranging from 5% at 10 min to 7% at 40 min of treatment. There were equivalent decreases in intradiscal pressure and disk height due to removal of similar amounts of nucleus during conventional diskectomy and during 40 min of percutaneous diskectomy.(ABSTRACT TRUNCATED AT 250 WORDS)

Far-lateral disk herniation: treatment by automated percutaneous diskectomy.

Automated percutaneous diskectomy has certain advantages over other surgical approaches to the treatment of far-lateral disk herniation; primarily, the procedure can be performed under local anesthesia without soft-tissue disruption. We describe four patients with far-lateral herniations who were successfully treated with the procedure.

Lumbar percutaneous diskectomy.

The lumbar percutaneous diskectomy is a new procedure for the treatment of herniated lumbar intervertebral disks that have not advanced to sequestration, fibrosis, or osteophyte formation. The procedure is done under local anesthesia, and there is no entrance into the spinal canal.

Percutaneous diskectomy for disk space infections.

To diagnose and treat intervertebral disk space infection, we used percutaneous diskectomy in four patients to harvest a large amount of disk material and to decompress and lavage the infected disk space with a broad spectrum antibiotic solution. This treatment regimen rapidly diminished pain and shortened the acute clinical course of the process. The long-term course in this small number of patients, however, appears not to have been altered.

Percutaneous diskectomy in the treatment of pediatric lumbar disk disease.

Intervertebral lumbar disk herniation in children and adolescents is rare. The incidence varies between 0.8% and 3.8% of all disks treated surgically. The uncertainty concerning operative or conservative treatment of this rare clinical entity has led to considering the use of atraumatic techniques, such as chemonucleolysis or percutaneous diskectomy. We report the unusual case of an 11-year-old girl with herniated disk at the L4-5 level treated by percutaneous diskectomy. This is, to our knowledge, the first case of a child treated by this technique. The technical simplicity, the minimal trauma it causes, and the excellent clinical result show that percutaneous diskectomy is a reasonable therapeutic alternative in the treatment of juvenile disks.

[Automated endoscopic percutaneous diskectomy in the treatment of lumbar disk hernia].

Results of the conventional lumbar disc herniation surgery are not always satisfactory, in spite of the progress made in microsurgical technique. For that reason neurosurgeons started looking for an alternative method of treatment. A combination of the percutaneous posterolateral approach, which was used in chemonucleolysis, accompanied by the development of diagnostics, surgical techniques and technology of medical instruments, are important stages in the development of automatic endoscopic percutaneous diskectomy. The aim of percutaneous diskectomy is derived from pathophysiological principles, i.e. it is based on the reduction of nucleus pulposus volume, namely on the lowering of intradiscal pressure, under the condition that the anulus fibrosus continuity has been preserved. In the past three years 132 patients have been treated with this method with the success rate of 81%. We consider this method to be the best way to the final goal which can be called the protective lumbar disc surgery.

Percutaneous diskectomy for lumbar disk herniation. A preliminary report.

Percutaneous diskectomy is a new method for reducing lumbar disk herniation. This procedure is simple, safe, and only semiinvasive since it causes no direct damage to the dura or nerve roots. This technique employs a nucleotome (blunt-tipped, suction-cutting probe) with a rotating electric shaver (3 mm in diameter) that was specially developed for this procedure. It was applied to 117 patients with lumbar disk herniation whose sciatica had not been relieved by conservative treatments. The results of the technique were considered effective in 94 patients (80.3%). The improvements were even more marked in patients with protrusion or prolapse type herniation. Reviewed with postoperative examinations using magnetic resonance imaging (MRI), excision of the herniated disk, resulting in decompression of the nerve root, may be correlated with the relief of symptoms.

Retrorenal colon: implications for percutaneous diskectomy.

It has been recommended that computed tomography (CT) with the patient prone be performed in every patient undergoing percutaneous diskectomy; this would enable detection of a retrorenal location of the colon, which could interfere with the percutaneous procedure. In this evaluation of 346 prone CT studies, only one patient (0.29%) was found to have retrorenal or retropsoas bowel that would have been perforated at diskectomy. Because of this extremely low prevalence, the performance of prone CT in every patient undergoing percutaneous lumbar diskectomy is not believed to be necessary.

Automated percutaneous diskectomy: initial patient experience. Work in progress.

A new method has been developed for percutaneously decompressing herniated lumbar disks. The method entails gaining access to the disk space through the use of an introduction system and a cannula. A 2-mm aspiration probe called a Nucleotome is then placed through the cannula into the disk space, and the nucleus pulposus is aspirated. Thirty-six patients have undergone the procedure, with a successful result in 31. There were no significant complications encountered, and the procedure is now being done on an outpatient basis. These preliminary results indicate that automated percutaneous diskectomy has the potential to replace laminectomy in the treatment of uncomplicated herniated disks.

[The results of percutaneous diskectomy. The course of pain, work capacity and therapy failure].

In a prospective study extending from November 1989 to December 1992 percutaneous discectomy was carried out in 50 patients (26 men, 24 women, mean age 41 [19-73] years). The aim of the study was to ascertain the efficacy of this new mode of treatment, and its indications. The patients selected for the procedure had chronic, therapy-resistant lumboradicular pain syndrome of at least six weeks' duration; imaging procedure had to show a "bulging disc" and neurological deficits had to be no more than minor. During the subsequent follow up period of 22 +/- 9.6 months 35 of the 50 patients did not require any further surgery; 24 of them (69%) resumed full work while seven (20%) regained partial (50%) working capacity. However, the operation proved ineffective in four of these 35 patients (11%). Fourteen of the 50 patients (28%) had persistent pain and required revision by open classical discectomy; seven of them resumed full work and one regained 50% working capacity. The most frequent findings at this revision were stenosis of the subarticular recess in combination with persistent forward bulging of the longitudinal ligament and anulus fibrosus (n = 7), calcification of the posterior longitudinal ligament (n = 1) and an intervertebral disc sequestrum which gave a false negative results on discography (n = 2). In another case there was a genuine recurrence 35 months after a successful percutaneous procedure; this was treated successfully by open operation. When performed at the level L5/S1, the procedure gave unsatisfactory results in five out of six cases.(ABSTRACT TRUNCATED AT 250 WORDS)

[Automated percutaneous diskectomy. Indication, technique and results after 2 years].

Automated percutaneous lumbar discectomy (APLD) is a new method for the treatment of herniated lumbar disc. Since 1988 it is introduced in Germany. Until December 1989 the operation has been performed in 45 patients at the department of orthopaedic surgery, University of Kiel. The 2-years experiences with the new method are reported in this paper. Careful selection of patients provides excellent or good results in 70%, in 18% the method fails.

Percutaneous diskectomy in the treatment of herniated lumbar disks.

APLD and the minimally invasive approach to spine surgery has stood the test of time successfully. With the advent of new imaging technologies to aid in the guidance of spine procedures, such as three-dimensional ultrasound, interventional MR imaging, and fluoroscopic CT, and the development of flexible instruments that can be navigated within the disk, the stage is now set for major breakthroughs in the treatment of herniated lumbar disks (i.e., the minimally invasive removal of extruded and free disk fragments). With the active role of radiologists and sophisticated imaging, minimally invasive spinal intervention has a bright and exciting future.
