Minimally Invasive Surgery (MIS) is surgery of the chest, abdomen, spine and pelvis, done with the aid of a viewing scope, and specially designed instruments. Benefits of minimally invasive surgery are less pain, less need for post-surgical pain medication, less scarring and less likelihood for incisional complications. Since the late 1980's, minimally invasive surgery has gained widespread acceptance because of the such advantages. However there are significant disadvantages which have, to date, limited the applications for these promising techniques. The reasons are limited degree-of-freedom, reduced dexterity and the lack of tactile feeling. To overcome such disadvantages many researchers have endeavored to develop robotic systems. Even though some robot aided systems achieved success and commercialized, there still remain many thing to be improved. In this paper, the robotic system which can mimic whole motions of a human arm by adding additional DOF is presented. The suggested design is expected to provide surgeons with improved dexterity during minimally invasive surgery.

Recently, an increasing interest in less invasive surgery has led to the advent of laparoendoscopic single-site surgery (LESS) and natural orifice transluminal endoscopic surgery (NOTES). LESS and NOTES could be technically challenging, but available literature has demonstrated the feasibility and safety of LESS for benign gynecologic diseases. However, the evidence is not strong enough to recommend the use of LESS over that of conventional multiport laparoscopic surgery (MLS). As per the results of the most recently published meta-analysis, the majority of surgical outcomes are equivalent between LESS and MLS, except for the longer operative time in LESS for both adnexal surgery and hysterectomy. Although an increasing number of studies have reported on robotic LESS, NOTES, and LESS for gynecologic malignancy, definite conclusions have not been drawn owing to the lack of sufficient information.

The establishment of minimally invasive surgery is a complex and difficult task. Video-assisted thoracic surgery (VATS) refers to a minimally invasive surgical technique that represents a less invasive approach to thoracic surgery using thoracoscopy. For lung cancer or esophageal cancer surgery, planning and establishing a team for minimally invasive surgery for the first time is not a simple task. Technical advances in surgical devices and the enhanced skill of surgeons are cornerstones of the development of minimally invasive surgery. Here, we review the meaning of minimally invasive thoracic surgery and discuss how to establish a team approach for VATS procedures.

Minimally invasive surgery (MIS) has several advantages over conventional open surgery. Less pain, less morbidity, early recovery and better cosmetic outcomes are well-known benefits of MIS. However, indications of MIS are highly dependent on the experience of surgeon and the disease status, In the benign diseases with less surgical complexity, MIS can be performed relatively and safely. However. in advanced malignant diseases which require more complex surgical manipulation, the of patients and the principles of oncologic surgery should be considered before the selection of surgical methods, MIS would be performed more and more with aid or technologic advancement. However, long-term result with equivalent oncologic outcomes to open surgery is necessary to be one of standard surgical treatments in thoracic surgery.

Although the incidence of descending necrotizing mediastinitis(DNM) is low, this is a serious disease because it"s mortality have been reported to be as high as 40∼50%. Currently, many authors have emphasized aggressive surgical approaches rather than medical treatment alone. We report good results in 2 DNM patients treated by less invasive approach with video-assisted thoracoscopic surgery, Less invasive methods with video-assisted thoracoscopic surgery can reduce hospital stay and morbidity if effective drainage can be achieved in selected DNM patients.

With the marked decrease in operative mortality in simple heart diseases there have been several reports on the minimally invasive and cosmetic techniques including submammary incision right parasternal approach right anterolateral thoracotomy partial sternotomy and subxiphoid approach. We report here subxiphoid approach without sternotomy for the repair of atrial septal defect as the procedure that has less invasive technique and more cosmetic effect.

Surgical treatment of the degenerative disc disease has evolved from traditional open spine surgery to minimally invasive spine surgery including endoscopic spine surgery. Constant improvement in the imaging modality especially with introduction of the magnetic resonance imaging, it is possible to identify culprit degenerated disc segment and again with the discography it is possible to diagnose the pain generator and pathological degenerated disc very precisely and its treatment with minimally invasive approach. With improvements in the optics, high resolution camera, light source, high speed burr, irrigation pump etc, minimally invasive spine surgeries can be performed with various endoscopic techniques for lumbar, cervical and thoracic regions. Advantages of endoscopic spine surgeries are less tissue dissection and muscle trauma, reduced blood loss, less damage to the epidural blood supply and consequent epidural fibrosis and scarring, reduced hospital stay, early functional recovery and improvement in the quality of life & better cosmesis. With precise indication, proper diagnosis and good training, the endoscopic spine surgery can give equally good result as open spine surgery. Initially, endoscopic technique was restricted to the lumbar region but now it also can be used for cervical and thoracic disc herniations. Previously endoscopy was used for disc herniations which were contained without migration but now days it is used for highly up and down migrated disc herniations as well. Use of endoscopic technique in lumbar region was restricted to disc herniations but gradually it is also used for spinal canal stenosis and endoscopic assisted fusion surgeries. Endoscopic spine surgery can play important role in the treatment of adolescent disc herniations especially for the persons who engage in the competitive sports and the athletes where less tissue trauma, cosmesis and early functional recovery is desirable. From simple chemonucleolysis to current day endoscopic procedures the history of minimally invasive spine surgery is interesting. Appropriate indications, clear imaging prior to surgery and preplanning are keys to successful outcome. In this article basic procedures of percutaneous endoscopic lumbar discectomy through transforaminal and interlaminar routes, percutaneous endoscopic cervical discectomy, percutaneous endoscopic posterior cervical foraminotomy and percutaneous endoscopic thoracic discectomy are discussed.

Percutaneous coronary intervention including intracoronary stenting is currently an accepted treatment modality in the treatment of coronary artery disease and is widely performed to treat the patient with multivessel disease with decreased morbidities and less cost compared with conventional coronary rtery bypass grafting(CABG), Repeated interventions due to restenosis even after successful angioplasty are the major disadvantage of the angioplsty especially when the lesion is located inthe left anterior descending artery(LAD) Recently CABG through left anterior small thoracotomy using the left internal thoracic artery to revascularize the LAD territory without cardiopulmonary bypass so called Minimally Invasive Direct Coronary Artery Bypass(MIDCAB) was intrduced and performed with comparable early outcomes. In this regard the integrated approach with percutaneous coronary intervention and minimally invasive direct coronary artery bypass surgery so called 'Hybrid CABG' was suggested to be an effective treatment in suitable patients with multivessel coronary artery disease. We report three cases of Hybrid CABG.

Traditionally, the main strategy of treatment of the head and neck cancer was en bloc resection including adjacent normal tissues through wide incision. However, the procedures may leave severe functional deficit such as swallowing difficulty, aspiration, and wide neck scar. Therefore, many attempts have been made up to minimize these morbidities. Of them, the minimal invasive approach such as transoral laser microsurgery (TLM) and transoral robot surgery (TORS) have been spolighted as a sensible strategy for organ preservation of the head and neck cancer patients. Results of TLM are equivalent to those obtained by conventional surgery, with considerably less morbidity, less hospital time and better postoperative function. Oncologic results of TLM are equivalent to conventional surgery. TORS are safe, feasible, and promising but oncologic safety is not yet verified. This article covers to current application of TLM and TORS, their advantages and limitations, and future direction.
