Median sternotomy incision is world-widely used for open heart surgery, especially in valvular heart disease. But recently, minimally invasive approach by the right parasternal incision for valvular heart disease was introduced with the many merits by small incision. We experienced 1 case of mitral valve repalcement by right parasternal incision and extended transseptal approach. This technique has no specific compli ations or problems compared with the median sternotomy and was proven by the excellent exposure. Cosmetically, the patient was satisfied with the incision.

Tubular retractor system as a minimally invasive surgery (MIS) technique has many advantages over other conventional MIS techniques. It offers direct visualization of the operative field, anatomical familiarity to spine surgeons, and minimizing tissue trauma. With technical advancement, many spinal pathologies are being treated using this system. Namely, herniated discs, lumbar and cervical stenosis, synovial cysts, lumbar instability, trauma, and even some intraspinal tumors have all been treated through tubular retractor system. Flexible arm and easy change of the tube direction are particularly useful in contralateral spinal decompression from an ipsilateral approach. Careful attention to surgical technique through narrow space will ensure that complications are minimized and will provide improved outcomes. However, understanding detailed anatomies and keeping precise surgical orientation are essential for this technique. Authors present the technical feasibility and initial results of use a tubular retractor system as a minimally invasive technique for variaties of spinal disorders with a review of literature.

Various operative techniques are available for the treatment of craniosynostosis. The patient's age at presentation is one of the most important factors in the determination of the surgical modality. Minimally invasive suturectomy and postoperative helmet therapy may be performed for relatively young infants, whose age is younger than 6 months. It relies upon the potential for rapid brain growth in this age group. Its minimal invasiveness is also advantageous. In this article, we review the advantages and limitations of minimally invasive suturectomy followed by helmet therapy for the treatment of craniosynostosis.

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.

A 43-year-old man with symptomatic hypertrophic obstructive cardiomyopathy (HOCM) was admitted to our hospital with aggravated exertional dyspnea and successfully treated with robotic transmitral septal myectomy. Minimally invasive transmitral septal myectomy may be a feasible surgical option for the treatment of HOCM in selected cases as an alternative to transaortic myectomy.

We report the case of a patient with mitral regurgitation complicated by type B dissection and Marfan syndrome (MFS) who was managed successfully with minimally invasive mitral valve repair. Without type A aortic dissection or aortic root dilation, MFS patients may develop mitral valve regurgitation, as in this case, and need valve surgery to improve their symptoms and long-term survival. However, it is not clear that a full sternotomy and prophylactic aortic surgery are necessary. Although retrograde perfusion to the dissected aorta is controversial, our approach minimizes the risk of future anticipated aortic surgery in MFS patients.

A 73-year-old woman who underwent combined bioprosthetic mitral valve replacement, tricuspid ring annuloplasty, and coronary artery bypass grafting 12 years previously visited our clinic due to aggravated dyspnea caused by structural valve deterioration of the mitral prosthesis. Because aortic or femoral artery cannulation and cross-clamping would have a high risk of stroke owing to severe calcification of the ascending aorta and ilio-femoral vessels, and because there was a risk of redo sternotomy due to the patent bypass grafts, a comprehensive approach including axillary artery cannulation, a minimally invasive right thoracotomy approach, and a clampless hypothermic fibrillatory arrest technique was used during redo mitral valve replacement.

To improve the cosmetic results of removing epidermal cysts, minimally invasive methods have been proposed. We proposed a new minimally invasive method that completely removes a cyst through a small hole made by a $CO_2$ laser. Twenty-five patients with epidermal cysts, which were 0.5 to 1.5 cm in diameter, non-inflamed, and freely movable, were treated. All of the patients were satisfied with the cosmetic results. This method is simple and results in minimal scarring and low recurrence rates without complications.

The market sales of fresh-cut fruit and vegetables have grown rapidly in recent decades as a result of changes in consumer trend. Choosing the proper pretreatment of fruit and vegetables before minimally processing is very important because appearance is the most fundamental factors affecting the quality of fresh-cut products. This review describes the biochemical bases for color changes of fruit and vegetables including browning, discoloration, and color changes of carrots and alliums. Understanding pathway of pigments in minimally processed fruit and vegetable and preventing the way of color change should be emphasized for successive packaging system. This review also describes pretreatment of fresh-cut fruit and vegetables to improve the prolonging the shelf-life and maintenance of its qualities.

Recently, minimally invasive approach via limited incision becomes one of the rapidly developing strategy in cardiac surgery as it gives less surgical trauma and is more satisfactory to the patients in respect to operative scar although the surgical technique is more demanding. Here, we report two cases of aortic valve replacement via limited transsternal incision. The methodology is described with review of the relevant literature.
