There are several types of minimally invasive approaches for thymectomy, of which the transpleural approach by video-assisted thoracoscopic surgery is particularly useful. In this approach, thymectomy is performed from either side of the thoracic cage. Thoracic surgeons should be familiar with the principles of the procedure, the anatomy of the region, and surgical strategies for successful thymectomy. The details of transpleural thymectomy are discussed herein.

Totally robotic esophagectomy is performed using a robotic technique without additional thoracoscopy or laparoscopy. However, most robotic esophagectomies are currently performed in a hybrid form combining robotic and other endoscopic techniques. Laparoscopic stomach mobilization and thoracoscopic esophagogastric anastomosis are commonly used methods in robotic esophagectomy. In this paper, totally robotic esophagectomy without thoracoscopic or laparoscopic assistance is presented.

Local treatment for tumors has developed from extended radical surgery to function preserving surgery on the basis of modern biology. With the development of minimally invasive technique, it changed to be minimal-invasive surgery. And nowadays technical revolution made non-invasive surgery possible with appearance of several kinds of non-surgical knives such as gamma knife, cyber knife, and HIFU (high intensity focused ultrasound) knife. In this article, history, HIFU machine and treatment procedure, histological change and its mechanism, clinical applications, advantage, disadvantage, and future prospect of extracorporeal high intensity focused ultrasound therapy using HIFU knife will be reviewed.

Background: Kyphoplasty is a minimally invasive procedure that can stabilize osteoporotic and neoplastic vertebral fractures. We retrospectively evaluated the clinical outcomes of kyphoplasty for the treatment of vertebral compression fractures in cancer patients. Methods: We reviewed the clinical data of 27 cancer patients who were treated with kyphoplasty (55 vertebral bodies) between May 2003 and Feb 2008. The clinical parameters, using a visual analog 10 point scale (VAS) and the mobility scores, as well as consumption of analgesic, were evaluated preoperatively and at 1 week after kyphoplasty. Results: A total 55 cases of thoracic and lumbar kyphoplasties were performed without complications. The mean age of the patients was 66 years. All the patients experienced a significant improvement in their subjective pain and mobility immediately after the procedures. The pain scores (VAS), mobility scores and other functional evaluations using the Oswestry disability score and the SF-36 showed significant differences between the pre- and postoperational conditions. Conclusions: Kyphoplasty is an effective, minimally invasive procedure that can relieve the pain of patients with vertebral compression fractures and these fractures are the result of metastasis.

Background: Nucleoplasty is a minimally invasive spinal surgery using a $Coblation^{(R)}$ technique that creates small voids within the disc. The purpose of this study was to evaluate the efficacy of cervical nucleoplasty in patients with cervical disc disorder. Methods: Between March 2008 and December 2009, 22 patients with cervical disc disorders were treated with cervical nucleoplasty after failed conservative treatment. All procedures were performed under local anesthesia, and fluoroscopic guidance and voids were created in the disc with the $Perc^{TM}$ DC Spine $Wand^{TM}$. Clinical outcomes were evaluated by the Modified Macnab criteria and VAS score at preprocedure, postprocedure 1 month, and 6 months. Results: Six patients had one, eight patients had two and eight patients had three discs treated; a total of 46 procedures was performed. Mean VAS reduced from 9.3 at preprocedure to 3.7 at postprocedure 1 month and to 3.4 at postprocedure 6 months. There was no significant complication related to the procedure within the first month. Outcomes were good or excellent in 17/22 (77.3%) cases. Postprocedure magnetic resonance imaging was acquired in two patients after two months showing morphologic evidence of volume reduction of protruded disc material in one patient but not in the other. Conclusions: Percutaneous decompression with a nucleoplasty using a $Coblation^{(R)}$ technique in the treatment of cervical disc disorder is a safe, minimally-invasive and less uncomfortable procedure, with an excellent short-term clinical outcome.

Transoral microsurgery has come a long way as a go-to surgical intervention technique for head and neck cancers. This minimally invasive procedure had gained acceptance through comparative clinical studies against radical neck surgical procedures, radiotherapy, and chemotherapy. Laser technology has vastly improved the oncological outcomes of this procedure and brought about an appreciation of transoral laser surgery (TLM) as a mainstay for re-sectioning malignant tumors along the throat. As an established procedure, TLM has undergone several upgrades regarding the different energy devices used for cutting, ablation, and hemostasis. Continued advances in automation have eventually led to surgical robotics, resulting in the emergence of transoral robotic surgery (TORS) as a viable advanced alternative for TLM. Similarly, expansions and enhancements (image-based guidance, fluorescence spectroscopy, and advanced robotic system) have also been investigated as potential upgrades for TORS. This paper reviews a selection of publications on the significant technological advancements to TLM and TORS over the past five years.

Abdominal aortic aneurysm (AAA) can be defined as an abnormal, progressive dilatation of the abdominal aorta, carrying a substantial risk for fatal aneurysmal rupture. Endovascular aneurysmal repair (EVAR) for AAA is a minimally invasive endovascular procedure that involves the placement of a bifurcated or tubular stent-graft over the AAA to exclude the aneurysm from arterial circulation. In contrast to open surgical repair, EVAR only requires a stab incision, shorter procedure time, and early recovery. Although EVAR seems to be an attractive solution with many advantages for AAA repair, there are detailed requirements and many important aspects should be understood before the procedure. In this comprehensive review, fundamental information regarding AAA and EVAR is presented.

Background: Frontal sinus fractures are relatively rare. Their surgical management significantly differs depending on whether the posterior wall is invaded and the clinical features vary. A bicoronal incision or endoscopic approach can be used. However, the minimally invasive approach has been attracting attention, leading us to introduce a simple and effective surgical method using multiple-threaded Kirschner wires. Methods: All patients had isolated anterior wall fractures without nasofrontal duct impairment. The depth from the skin to the posterior wall was measured using computed tomography to prevent injury. The edge of the bone segment on the skin was marked, a threaded Kirschner wire was inserted into the center of the bone segment, and multiple Kirschner wires were gently reduced simultaneously. Results: Surgery was performed on 11 patients. Among them, seven patients required additional support for appropriate fracture reduction. Therefore, a periosteal elevator was used as an adjunct through a small sub-brow incision because the reduction was incomplete with the Kirschner wire alone. The reduction results were confirmed using facial bone computed tomography 1 to 3 days postoperatively. The follow-up period was 3 to 12 months. Conclusion: The patients had no complications and were satisfied with the surgical results. Here we demonstrated an easy and successful procedure to reduce a pure anterior wall frontal sinus fracture via non-invasive threaded Kirschner wire reduction.
