Invasive Techniques

Intradural, extramedullary schwannomas have long been treated with open midline incision, laminectomy, and dural opening to expose and resect the lesion. While this technique is well established, today new surgical techniques can be utilized to perform the same procedure while minimizing pain, size of incision, and trauma to adjacent tissues. In cases of intradural surgery, minimally invasive surgery limits the degree of soft tissue disruption. As a result, there is significant decreased dead space within the surgical cavity that may decrease the rate of CSF leak complications. Minimally invasive techniques have continuously improved over the years and have reached a point where they can be used for intradural surgeries. In this case presentation, we demonstrate a minimally invasive approach to the lumbar spine with resection of an intradural schwannoma. Surgical techniques and the nuances of the minimally invasive approach to intradural tumors compared to the standard open procedure will be discussed.

Abstract BACKGROUND: Although minimally invasive surgery for intradural tumors offers the potential benefits of less postoperative pain, a quicker recovery, and the avoidance of long-term instability from multilevel laminectomy, there are concerns over whether one can safely and effectively remove intradural extramedullary tumors in a fashion comparable to open techniques and whether the advantages of minimally invasive surgery are clinically significant. OBJECTIVE: To review our early experience with minimally invasive techniques for intradural extramedullary tumors of the spine. METHODS: Thirteen intradural tumors (1 cervical, 6 thoracic, 6 lumbar) in 11 patients were operated on using a muscle-splitting, tube-assisted paramedian oblique approach with hemilaminectomy to access the spinal canal while preserving the spinous process and ligaments. Fluoroscopy and navigation were used to determine the surgical level in all thoracic and lumbar cases. RESULTS: Satisfactory tumor resection using standard microsurgical techniques was achieved in all but 1 case using a minimally invasive approach. Surgical time and intraoperative blood loss were favorable compared with our open technique cases. There was no postoperative morbidity with the minimally invasive approach, although in 2 patients with tumors in the mid- and upper thoracic spine, the surgical incision was inaccurately placed by 1 level. In 1 case, the approach was converted to open when the tumor could not be found, and postoperatively there was a cerebrospinal fluid leak with infection that required readmission. CONCLUSION: Intradural extramedullary tumors can be safely and effectively removed using minimally invasive techniques. The pros and cons of minimally invasive vs open surgery are discussed.

Abstract Intradural extramedullary spinal tumors were historically managed through traditional midline approaches. Although conventional laminectomy or laminoplasty provides a wide tumor and spinal cord exposure, they may cause prolonged postoperative neck pain and late kyphosis deformity. Minimally invasive ipsilateral hemilaminectomy preserves midline structures, reduces the paraspinal muscle disruption, and could avoid postoperative kyphosis deformity. A safe tumor resection through this approach could be complicated in large sized or anteromedullary located lesions. We present a surgical video of C3 antero located meningioma removed en bloc through a minimally invasive approach.

Introduction. Harold Hirschsprung, a physician at Queen Louise Children’s Hospital of Copenhagen, first described the disease that now bears his name, at the Pediatric Congress of Berlin in 1886. Since then there have been countless debates on the optimal surgical approach. This paper aims both to recap the main classical surgical techniques: Swenson, Duhamel and Soave, but the main focus is on minimally invasive techniques. Surgical techniques. In the last 25 years, the treatment for Hirschsprung disease has progressed. If classically the preferred treatment was in 2-3 stages, now the definitive intervention is per primam in most cases, thus avoiding the morbidity associated with stomas. In 1995, Georgeson describes the minimally invasive approach using laparoscopy, and then in 1998, De la Torre et al, describes the first transanal endorectal pull-through (TERPT), unattended laparoscopically. Discussions. The initial discussions were linked to comparing processes in a single stage with ones in 2 or 3 stages, finding similar results, it is now a question of comparing open techniques with minimally invasive and even minimally invasive techniques with each other, endeavoring to establish whether laparoscopically assisted approach is needed or if the transanal one is enough. Conclusion. Usually shorter forms of Hirschsprung disease are treated strictly using the transanal technique, for the forms involving the left and transverse colon laparoscopically assisted transanal pull-through is used, while for the ascending colon and for the total aganglionosis the laparoscopically assisted Duhamel procedure is preferred.

AimsAiming to reduce the numbers of high risk autopsies, we use a minimally invasive approach. HIV/hepatitis C virus (HCV)-positive coronial referrals, mainly intravenous drug abusers, have full autopsy only if external examination, toxicology and/or postmortem CT scan do not provide the cause of death. In this study, we review and validate this protocol.Methods and results62 HIV/HCV-positive subjects were investigated. All had external examination, 59 toxicology and 24 CT. In 42/62, this minimally invasive approach provided a cause of death. Invasive autopsy was required in 20/62, CT/toxicology being inconclusive, giving a potential rather than definite cause of death. Autopsy findings provided the cause of death in 6/20; in the remainder, a negative autopsy allowed more weight to be given to toxicological results previously regarded as inconclusive. In order to validate selection of cases for invasive autopsy using history, external examination and toxicology, a separate group of 57 non-infectious full autopsies were analysed. These were consecutive cases in which there was a history that suggested drug abuse. A review pathologist, provided only with clinical summary, external findings and toxicology, formulated a cause of death. This formulation was compared with the original cause of death, based on full autopsy. The review pathologist correctly identified a drug-related death or requirement for full autopsy in 56/57 cases. In one case, diagnosed as cocaine toxicity by the review pathologist, autopsy additionally revealed subarachnoid haemorrhage and Berry aneurysm.ConclusionsThese findings support the use of minimally invasive techniques in high risk autopsies, which result in a two-thirds reduction in full postmortems.

OBJECTIVEHemangioblastomas are benign, highly vascularized tumors that can occur sporadically or as part of von Hippel-Lindau (VHL) disease. Traditionally, spinal hemangioblastomas have been surgically treated via an open approach. In recent years, however, minimally invasive techniques using tubular retractors have been increasingly applied in spine surgery. Such procedures involve less tissue trauma but are also particularly demanding for the surgeon, especially in cases of highly vascular tumors such as hemangioblastomas. The object of this study was to evaluate the safety and efficacy of minimally invasive resection of selected spinal hemangioblastomas.METHODSThe authors conducted a retrospective single-center study of all patients who, between January 2010 and January 2018, had been operated on for spinal hemangioblastoma via a minimally invasive approach performed at the surgeon’s discretion. The surgical technique is described and the pre- and postoperative neurological and imaging results were analyzed descriptively. The primary outcome was the postoperative compared to preoperative neurological condition (McCormick grade). The secondary outcomes were the extent of tumor resection and postoperative complications.RESULTSEighteen patients, 12 female and 6 male, harboring a total of 19 spinal hemangioblastomas underwent surgery in the study period. Seventeen patients had stable neurological findings with stable or improved McCormick grades (94.5%) at a mean of 4.3 months after surgery. One (5.5%) of the 18 patients developed progressive neurological symptoms with a worsened McCormick grade that did not improve in the long-term follow-up. Sixteen of the 18 patients had VHL disease, whereas 2 patients had sporadic spinal hemangioblastomas. In all patients, postoperative MRI showed complete resection of the tumors. No other surgery-related perioperative or postoperative complications were recorded.CONCLUSIONSA minimally invasive approach for the resection of selected spinal hemangioblastomas is safe and allows complete tumor resection with good clinical results in experienced hands.

The right anterior mini-incision has emerged as an effective minimally invasive approach for adult aortic root and valve operations. However, adoption of minimally invasive techniques has been limited in congenital heart surgery. We report a case of anomalous aortic origin of the right coronary artery repair performed through this approach. Following successful right coronary artery unroofing, the patient had an uncomplicated postoperative hospitalization.

AbstractMedian sternotomy incision has shown to be a safe and efficacious approach in patients who require thoracic aortic interventions and still represents the gold-standard access. Nevertheless, over the last decade, less invasive techniques have gained wider clinical application in cardiac surgery becoming the first-choice approach to treat heart valve diseases, in experienced centers. The popularization of less invasive techniques coupled with an increased patient demand for less invasive therapies has motivated aortic surgeons to apply minimally invasive approaches to more challenging procedures, such as aortic root replacement and arch repair. However, technical demands and the paucity of available clinical data have still limited the widespread adoption of minimally invasive thoracic aortic interventions. This review aimed to assess and comment on the surgical techniques and the current evidence on mini thoracic aortic surgery.

Object Resection of spinal tumors traditionally requires bilateral subperiosteal muscle stripping, extensive laminectomy, and, in cases of foraminal extension, partial or radical facetectomy. Fusion is often warranted in cases of facetectomy to prevent deformity, pain, and neurological deterioration. Recent reports have demonstrated safety and efficacy of mini-open removal of these tumors using expandable tubular retractors. The authors report their experience with the minimally invasive removal of extradural foraminal and intradural-extramedullary tumors using the nonexpandable tubular retractor. Methods A retrospective chart review of consecutive patients who underwent minimally invasive resection of spinal tumors at Notre Dame Hospital was performed. Results Between December 2005 and March 2012, 13 patients underwent minimally invasive removal of spinal tumors at Notre Dame Hospital, Montreal. There were 6 men and 7 women with a mean age of 55 years (range 20–80 years). There were 2 lumbar and 2 thoracic intradural-extramedullary tumors and 7 thoracic and 2 lumbar extradural foraminal tumors. Gross-total resection was achieved in 12 patients. Subtotal resection (90%) was attained in 1 patient because the tumor capsule was adherent to the diaphragm. The average duration of surgery was 189 minutes (range 75–540 minutes), and the average blood loss was 219 ml (range 25–500 ml). There were no major procedure-related complications. Pathological analysis revealed benign schwannoma in 8 patients and meningioma, metastasis, plasmacytoma, osteoid osteoma, and hemangiopericytoma in 1 patient each. The average equivalent dose of postoperative narcotics after surgery was 66.3 mg of morphine. The average length of hospitalization was 66 hours (range 24–144 hours). All working patients returned to normal activities within 4 weeks. The average MRI and clinical follow-up were 13 and 21 months, respectively (range 2–68 months). At last follow-up, 92% of patients had improvement or resolution of pain with a visual analog scale score that improved from 7.8 to 1.2. All patients with neurological impairment improved. The American Spinal Injury Association grade improved in all but 1 patient. Conclusions Intradural-extramedullary and extradural tumors can be completely and safely resected through a minimally invasive approach using the nonexpandable tubular retractor. This approach may be associated with even less tissue destruction than mini-open techniques, translating into a quicker functional recovery. In cases of foraminal tumors, by eliminating the need for facetectomy, this minimally invasive approach may decrease the incidence of postoperative deformity and eliminate the need for adjunctive fusion surgery.
