Abstract INTRODUCTION High-grade spondylolisthesis is a relatively uncommon condition. The optimal surgical approach for management remains debatable. Although in-situ fusion is preferred due to its lower risk of neural injury, it does not correct spinal alignment. In contrast, reduction corrects the deformity and provides a high rate of fusion, but has the potential for high rates of neural injury. We herein report our experience and surgical outcomes following minimally invasive versus open management of intermediate- to high-grade spondylolisthesis. METHODS A multicenter, retrospective cohort analysis of adult patients aged more than 18 yr with grade II or higher spondylolisthesis, who underwent surgery from January 2008 until February 2019, was performed. RESULTS Sixty-two patients were included in the final analysis. A total of 41 patients were treated with an open approach and 21 with a minimally invasive surgical approach (MIS). More specifically, 18 patients underwent in-situ fusion, 11 underwent MIS reduction, and 33 had an open reduction. The total rate of complications was 40.3%. The rate of complications in the MIS group was 52.3% compared to 34.1% in the open surgery group (P = .166). The rate of complications was 27.8% in the in-situ fusion group, 72.7% in the MIS-reduction group, and 36.4% in the open-reduction group. Our comparisons of the rate of complications in the no-reduction group vs the MIS-reduction group, and the MIS-reduction group vs the open-reduction group were statistically significant (P = .027 and P = .07, respectively). However, there was no statistically significant difference between the rate of complications in the no-reduction group vs the open-reduction group (P = .757), nor between the rate of complications in the MIS group vs the open surgery group (P = .166). CONCLUSION MIS reduction is associated with a high rate of complications in the management of high-grade spondylolisthesis.

Abstract BACKGROUND Osteoblastomas are locally aggressive bone tumors typically affecting the posterior elements of the vertebral column. The treatment of choice is total surgical resection, traditionally through an open laminectomy, often with facetectomy and fusion when the lesion is in the foramen. OBJECTIVE To seek an alternative to open surgery, allowing quick and full functional recovery, to meet the youth and athlete population's specific surgical goals. In this population especially, open surgery can be associated with significant impairment and morbidity. METHODS  We report a pediatric case of posterior L5 osteoblastoma completely removed using a facet-sparing and fusion-avoiding contralateral foraminal minimally invasive approach using a tubular retractor system. A 12-yr-old male competitive tennis player presented with progressive right L5 lumbosciatica. Computed tomography scan and magnetic resonance imaging revealed a lesion of the right L5 pedicle, facet, and vertebral body with significant foraminal soft-tissue extension. Being unfit for percutaneous radiofrequency ablation, the patient underwent a minimally invasive biopsy and resection using an 18-mm-wide METRx nonexpandable tubular retractor (Medtronic) through a contralateral approach, sparing the facet and avoiding fusion surgery. RESULTS Postoperative imaging showed residual tumor. The patient was reoperated in a similar fashion with complete tumor removal. His symptoms resolved completely postoperatively. He resumed tennis within 4 mo and remains symptom- and tumor-free at 12-mo follow-up. CONCLUSION Minimally invasive contralateral facet-sparing resection of a pediatric lumbar osteoblastoma is an alternative to standard technique and is associated with significant advantages for young athletes, such as quick and full functional recovery, along with avoidance of fusion when the facet joint is involved.

Abstract Background Lumbar interbody fusion is a standard technique for treating degenerative lumbar disorders involving instability. Due to its invasiveness, a minimally invasive technique, extraforaminal lumbar interbody fusion (ELIF), was introduced. On surgically approaching posterolaterally, the posterior muscles and spinal canal are barely invaded. Despite its theoretical advantage, ELIF is technically demanding and has not been popularised. Therefore, we developed a microendoscopy-assisted ELIF (mELIF) technique which was designed to be safe and less invasive. Here, we aimed to report on the surgical technique and clinical results. Methods Using a posterolateral approach similar to that of lateral disc herniation surgery, a tubular retractor, 16 or 18 mm in diameter, was placed at the lateral aspect of the facet joint. The facet joint was partially excised, and the disc space was cleaned. A cage and local bone graft were inserted into the disc space. All disc-related procedures were performed under microendoscopy. The spinal canal was not invaded. Bilateral percutaneous screw-rod constructs were inserted and fixed. Results Fifty-five patients underwent the procedure. The Oswestry Disability Index and visual analogue scale scores greatly improved. Over 90% of the patients obtained excellent or good results based on Macnab’s criteria. There were neither major adverse clinical effects nor the need for additional surgery. Conclusions mELIF is minimally invasive because the spinal canal and posterior muscles are barely invaded. It produces good clinical results with fewer complications. This technique can be applied in most single-level spondylodesis cases, including those involving L5/S1 disorders.

Abstract Background The aim of this study was to analyze overall survival in endometrial cancer patients’ FIGO stages I-III in relation to surgical approach; minimally invasive (MIS) or open surgery (laparotomy). Methods A population-based retrospective study of 7275 endometrial cancer patients included in the Swedish Quality Registry for Gynecologic Cancer diagnosed from 2010 to 2018. Cox proportional hazard models were used in univariable and multivariable survival analyses. Results In univariable analysis open surgery was associated with worse overall survival compared with MIS hazard ratio, HR, 1.39 (95% CI 1.18–1.63) while in the multivariable analysis, surgical approach (MIS vs open surgery) was not associated with overall survival after adjustment for known risk factors (HR 1.12, 95% CI 0.95–1.32). Higher FIGO stage, non-endometrioid histology, non-diploid tumors, lymphovascular space invasion and increasing age were independent risk factors for overall survival. Conclusion The minimal invasive or open surgical approach did not show any impact on survival for patients with endometrial cancer stages I-III when known prognostic risk factors were included in the multivariable analyses.

Despite there already being many studies on robotic surgery as a minimally invasive approach for non-small-cell lung cancer (NSCLC) patients, the use of this technique for stage III disease is still poorly described. These are the preliminary results of our prospective study on the safety and effectiveness of robotic approaches in patients with locally advanced NSCLC in terms of postoperative complications and oncological outcomes. Since 2016, we prospectively investigated 19 consecutive patients with NSCLC stage IIIA-pN2 (diagnosed by EBUS-TBNA) who underwent lobectomy and radical lymph node dissection with robotic approaches after induction treatment. Furthermore, we matched a case-control study with 46 patients treated with open surgery during the same period of time, with similar age, comorbidities, clinical stage and tumor size. The individual matched population was composed of 16 robot-assisted thoracic surgeries and 16 patients who underwent open surgery. The median time range of resection was inferior in the open group compared to robotic lobectomy (243 vs. 161 min; p < 0.001). Lymph node resection and positivity were not significantly different (p = 0.96 and p = 0.57, respectively). Moreover, no difference was observed for PFS (p = 0.16) or OS (p = 0.41). In conclusion, we demonstrated that the early outcomes and oncological results of N2-patients after robotic lobectomy were similar to those who had open surgery. Considering the advantages of minimally invasive surgery, robot-assisted lobectomy appears to be a safe approach to patients with locally advanced diseases.
