In cases with a double lesion, medial facetectomy is performed in parallel, and so the risk of instability is high following CIPA at the L5-S1 level due to facet joint disruption or post-operative spondylolysis. Accordingly, in the present study, the authors aimed to introduce the extreme lateral and interlaminar approach (ELIA), which can minimize facetectomy to prevent postoperative instability in cases with a double disc herniation at the L5-S1 level, and to compare the approach with the conventional CIPA procedure.</p><elsevierMultimedia ident="fig0005"></elsevierMultimedia><elsevierMultimedia ident="fig0010"></elsevierMultimedia></span><span id="sec0010" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0075">Material and methods</span><p id="par0010" class="elsevierStylePara elsevierViewall">The authors reviewed the medical charts of patients who underwent a procedure for a double disc herniation at the lumbosacral level (lumbar 5-sacral 1) between March 2012 and February 2016 at the study hospital.

And the procedure was done under general anesthesia. First, the herniated disc material was removed in the intracanal area using the standard interlaminar approach. To prevent postsurgical spondylolysis that can occur due to excessive laminotomy, laminotomy at L5 was minimized as much as possible. All the procedure of laminotomy and discectomy were performed by using surgical microscope. Decompression at the S1 root was confirmed by performing laminotomy in the upper portion of the sacral laminar. Subsequently, an extreme lateral approach (ELA) was performed to decompress the L5 root pressured in the intervertebral foramen. The angle at which to access the intervertebral foramen without violating the facet joint and the appropriate location for making the skin incision were determined using a preoperative MRI image. The skin incision was performed approximately 7–9<span class="elsevierStyleHsp" style=""></span>cm away from the midline (<a class="elsevierStyleCrossRefs" href="#fig0015">Figs. 3 and 4</a>). While the approach angle was roughly estimated, the paraspinal muscle was obliquely dissected and then the facet joints at L4-5 and L5-S1 were examined. Afterwards, a self-retaining Magana retractor was used and the isthmus at L5 was examined by sufficiently dissecting the muscle. In the absence of facet joint hypertrophy, access at an oblique angle enabled the examination of the lower portion of the facet joint, where the root was passing through, via muscle and ligament dissection. The L5 root was immediately examined through a sufficient and careful dissection of the ligaments. To prevent L5 nerve root injury during dissection of the intervertebral ligament, we started dissection at the caudal portion where L5 nerve root did not exist. Upper portion, especially at the junction of L5 transverse process and isthmus, L5 nerve root usually passes through. After finding out perineural fat zone, we did meticulous dissection to check L5 root and L5 pedicle. After the L5 root and L5 pedicle were examined, the root was carefully retracted to examine the herniated disc material and then, the disc material was removed (<a class="elsevierStyleCrossRef" href="#fig0025">Fig. 5</a>). For complete root decompression, the sacral ala was partially removed in the extraforaminal area and finally, the freely moving root was examined. If hypertrophy due to arthropathy in the facet joint was present, only a partial removal of the lower portion of S1 superior facet provided sufficient visibility. In some cases, visibility at the skin incision site was obstructed by the iliac bone, in which case a small portion of the iliac bone was removed to obtain visibility at the site.</p><elsevierMultimedia ident="fig0015"></elsevierMultimedia><elsevierMultimedia ident="fig0020"></elsevierMultimedia><elsevierMultimedia ident="fig0025"></elsevierMultimedia></span></span><span id="sec0025" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0090">Results</span><p id="par0025" class="elsevierStylePara elsevierViewall">A total of 35 patients underwent CIPA or ELIA at the study hospital to treat a double disc herniation at the L5-S1 level between March 2012 and February 2016.

In the ELIA group, there were a total of 11 patients (three men and eight women) and the mean age was 63.0 (±13.9) years, while in the CIPA group, there were a total of 24 patients (11 men and 13 women) (<a class="elsevierStyleCrossRef" href="#tbl0005">Table 1</a>). The mean follow-up length was 11.1 (±4.7) months in the ELIA group and 18.3 (±10.1) months in the CIPA group. The mean operation time was 88.8<span class="elsevierStyleHsp" style=""></span>min (±14.5) in ELIA and 86.8<span class="elsevierStyleHsp" style=""></span>min (±10.1) (<span class="elsevierStyleItalic">p</span>: 0.652). The preoperative K-ODI score was 34.1 (±3.3) months in the ELIA group and 32.4 (±4.0) months in the CIPA group (<span class="elsevierStyleItalic">p</span>: 0.23). Postoperative K-ODI scores in the ELIA and the CIPA groups were 8.2 (±4.1) and 8.1 (±3.2) (<span class="elsevierStyleItalic">p</span>: 0.97) at month one; 6.4 (±2.1) and 7.1 (±3.5) (<span class="elsevierStyleItalic">p</span>: 0.54) at month two; and 5.3 (±2.4) and 8.4 (±6.4) (<span class="elsevierStyleItalic">p</span>: 0.005) at month three, respectively. Thus, only the postoperative K-ODI scores at month three showed a significant between-group difference.

Several surgical techniques have been introduced in the treatment of double lumbar disc herniation. The simplest is to remove the intracanal disc material following the interlaminar approach and then to remove the disc material of the foraminal lesion following extended medial facetectomy.<a class="elsevierStyleCrossRefs" href="#bib0175"><span class="elsevierStyleSup">6,11–13</span></a> However, in this approach, the extra foraminal lesion is not accessible and, even though an attempt is made to remove the disc material of the foraminal lesion, it is highly likely for some to be left behind. Another disadvantage is that if medial facetectomy is excessively performed, the risk of instability is high due to postoperative spondylolysis or facet disruption.<a class="elsevierStyleCrossRefs" href="#bib0170"><span class="elsevierStyleSup">5,14–16</span></a> Accordingly, some authors have recommended performing total facetectomy in parallel.<a class="elsevierStyleCrossRefs" href="#bib0170"><span class="elsevierStyleSup">5,6,13,16</span></a> However, this approach has also been criticized because of a high risk of postoperative instability or chronic pain after surgery. Thus, there are authors who recommend performing intervertebral fusion surgery after total facetectomy to treat double lumbar disc herniation.<a class="elsevierStyleCrossRefs" href="#bib0170"><span class="elsevierStyleSup">5,17</span></a> Notably, though, fusion surgery takes a relatively long time and causes a large amount of blood loss, increasing the risk for various complications. It is also expensive. For direct access to the foramen, pars interarticularis fenestration has been introduced by Di Lorenzo and colleagues,<a class="elsevierStyleCrossRef" href="#bib0235"><span class="elsevierStyleSup">18</span></a> but this approach is disadvantageous in that only limited exposure is possible, and that there is a concern about a postoperative fracture of the pars.<a class="elsevierStyleCrossRef" href="#bib0240"><span class="elsevierStyleSup">19</span></a> Hence, the CIPA approach was introduced by some authors, and many advantages of the approach have been highlighted.<a class="elsevierStyleCrossRefs" href="#bib0180"><span class="elsevierStyleSup">7,8,20,21</span></a> In CIPA, the transversing root and the exiting root are simultaneously visible, and the lesion can be removed without destroying the facet joint, resulting in a low likelihood of postoperative instability. Particularly, the paraisthmic approach is a very useful surgical technique, as access to the foramen is possible only with a partial removal of the superior-lateral portion of the facet joint.<a class="elsevierStyleCrossRefs" href="#bib0255"><span class="elsevierStyleSup">22–25</span></a> However, the problem is that when this approach is used at the L5-S1 level, excessive facetectomy or excessive removal of isthmus can happen.<a class="elsevierStyleCrossRefs" href="#bib0275"><span class="elsevierStyleSup">26–28</span></a> The lateral pars at L5 are located up to the outer portion of the intervertebral foramen, unlike those at other levels, and thus, an excessive removal of isthmus is necessary to completely expose the foramen.<a class="elsevierStyleCrossRefs" href="#bib0285"><span class="elsevierStyleSup">28,29</span></a> In contrast, in the paraisthmic approach, a foramen lesion can easily be resolved without removing isthmus because at upper lumbar levels such as at L2-3 or L3-4, isthmuses are located further in relative to the intervertebral foramen (<a class="elsevierStyleCrossRef" href="#fig0010">Fig. 2</a>). However, this is not the case in some lesions at L4-5 and most lesions at L5-S1. Accordingly, for lesions at the L5-S1 level, the authors attempted to remove foraminal or extraforaminal disc materials without performing lateral facetectomy or removing isthmus by using an extreme lateral approach. With the ELIA approach, it was possible to resolve most lesions without involving the facet joint, and excellent outcomes on pain and K-ODI was observed during the follow-up in comparison with following the CIPA approach. Even in cases with facet arthropathy, access was possible through minimal superior facet undercutting, and the facet joint was never involved. With respect to reoperation, 31.4% of patients in the CIPA group underwent reoperation, whereas none did so in the ELIA group. Of course, the follow-up period was relatively short and statistical significance was not obtained, but the authors believe that the statistics are meaningful in their own right. The study has limitations in that it was a retrospective study, and its sample size was relatively small. And the total follow-up period was relatively short. And there were not exact records about last follow-up outcome. It was because of retrospective study. In the future, an effort should be made to derive more meaningful outcomes by using a larger sample and by observing patients for a longer follow-up period.</p><p id="par0035" class="elsevierStylePara elsevierViewall">In the treatment of L5-S1 double disc herniation, the ELIA surgical approach showed better outcomes than the CIPA surgical approach did with respect to pain and K-ODI during a mid-term follow-up examination conducted three months post-operation.</p></span><span id="sec0035" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0100">Funding</span><p id="par0040" class="elsevierStylePara elsevierViewall">This research did not receive any specific grant from funding agencies in the public, commercial, or not-for-profit sectors.</p></span><span id="sec0040" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0105">Conflicts of interest</span><p id="par0045" class="elsevierStylePara elsevierViewall">The authors have no conflicts of interest to declare.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:12 [ 0 => array:3 [ "identificador" => "xres1155336" "titulo" => "Abstract" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0005" "titulo" => "Introduction and objectives" ] 1 => array:2 [ "identificador" => "abst0010" "titulo" => "Patients and methods" ] 2 => array:2 [ "identificador" => "abst0015" "titulo" => "Results" ] 3 => array:2 [ "identificador" => "abst0020" "titulo" => "Conclusions" ] ] ] 1 => array:2 [ "identificador" => "xpalclavsec1082900" "titulo" => "Keywords" ] 2 => array:2 [ "identificador" => "xpalclavsec1082899" "titulo" => "Abbreviations" ] 3 => array:3 [ "identificador" => "xres1155337" "titulo" => "Resumen" "secciones" => array:4 [ 0 => array:2 [ "identificador" => "abst0025" "titulo" => "Introducción y Objetivos" ] 1 => array:2 [ "identificador" => "abst0030" "titulo" => "Pacientes y Métodos" ] 2 => array:2 [ "identificador" => "abst0035" "titulo" => "Resultados" ] 3 => array:2 [ "identificador" => "abst0040" "titulo" => "Conclusiones" ] ] ] 4 => array:2 [ "identificador" => "xpalclavsec1082898" "titulo" => "Palabras clave" ] 5 => array:2 [ "identificador" => "sec0005" "titulo" => "Introduction" ] 6 => array:3 [ "identificador" => "sec0010" "titulo" => "Material and methods" "secciones" => array:2 [ 0 => array:2 [ "identificador" => "sec0015" "titulo" => "Statistical analysis" ] 1 => array:2 [ "identificador" => "sec0020" "titulo" => "Surgical technique" ] ] ] 7 => array:2 [ "identificador" => "sec0025" "titulo" => "Results" ] 8 => array:2 [ "identificador" => "sec0030" "titulo" => "Discussion" ] 9 => array:2 [ "identificador" => "sec0035" "titulo" => "Funding" ] 10 => array:2 [ "identificador" => "sec0040" "titulo" => "Conflicts of interest" ] 11 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2018-04-30" "fechaAceptado" => "2018-07-29" "PalabrasClave" => array:2 [ "en" => array:2 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec1082900" "palabras" => array:4 [ 0 => "Combined approach" 1 => "Disc herniation" 2 => "Lumbosacral junction" 3 => "Lumbar" ] ] 1 => array:4 [ "clase" => "abr" "titulo" => "Abbreviations" "identificador" => "xpalclavsec1082899" "palabras" => array:6 [ 0 => "ELIA" 1 => "CIPA" 2 => "CT" 3 => "MRI" 4 => "K-ODI" 5 => "NRS" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec1082898" "palabras" => array:4 [ 0 => "Abordaje combinado" 1 => "Hernia discal" 2 => "Unión lumbosacra" 3 => "Lumbar" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:3 [ "titulo" => "Abstract" "resumen" => "<span id="abst0005" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0010">Introduction and objectives</span><p id="spar0005" class="elsevierStyleSimplePara elsevierViewall">There are several approaches for double disc herniation consisting of an intracanal and foraminal lesion.
