A coronary artery fistula was surgically ligated in a 38-year-old woman via a left anterior mini-thoracotomy without the use of cardiopulmonary bypass. In selected cases, this surgical approach can provide an excellent surgical exposure for coronary artery fistula ligation. It also offers an excellent cosmetic result and shorter hospital stay.

The operation for esophageal cancer is both complex and challenging, and may be associated with significant morbidity and mortality compared to other oncologic surgeries. Minimally invasive surgeries have been applied on various kinds of surgery to enhance better recovery with minimal surgical complications. But for the esophageal cancer, it has not been actively applied yet. With improvement in instrumentations and increasing experience with endoscopic surgical techniques, minimally invasive surgical approaches to esophageal cancer are being explored to determine feasibility, results and potential advantages. We experienced eight cases of minimally invasive surgery for esophageal cancer and report here focusing on surgical techniques and tips.

Pectus excavatum is rare, but it is the most common type of sternal congenital disorder. There are many surgical methods to correct pectus excavatum such as the Ravitch method, Wada method, Silastic mold method, and the Nuss operation. We report a case of minimal invasive surgery for pectus excavatum using a polyvinyl alcohol sponge.

Background: Recent trends suggest that minimally invasive cardiac surgery reduces postoperative morbidity and offers a cosmetic benefit. This study was performed to evaluate the CPB time, ACC time, OP time, ICU stay and postoperative hospital stay following a lower partial sternotomy and those of the median sternotomy. Material and Method: A group of 26 adult patients who underwent cardiac surgery through lower partial sternotomy from August 1997 to July 1999(A group) were compared to 45 adult patients who underwent cardiac surgery through median sternotomy from January 1996 to July 1997(B group). The mean ages(46.4$\pm$14.6 years, A group and 46.8$\pm$13.2 years, B group) were similar. Operations were performed with central cannula and antegrade/retrograde blood cardioplegia. Result: There was no death in each group. No differences were found in CPB time, ACC time, OP time, ICU stay and postoperative hospital stay. Postoperative complications were sternal splitting in a patient in group A and a patient with bleeding that required reoperation and a patient with delayed wound closure in group B. Conclusion: The lower partial sternotomy offered a cosmetic benefit, but does not significantly reduced the length of operative time and hospital stay. Minimally invasive cardiac surgery will be applied increasing because of the suggested advantage and choosing a proper operative technique will be helpful.

Mediastinal lymph node dissection is a method that increases the long term survival of patients with an esophageal carcinoma. However, dissection of the left mediastinal lymph node is almost impossible, as it is not easy to see. Herein, a left mediastinal lymph node dissection, with thoracoscopy through a cervical incision wound during minimal invasive esophageal surgery, is reported.

Recently, the incidence of Achilles tendon rupture has been increasing with an increase in the elderly and the sports population. Various kinds of surgical options have been introduced up to now. Among them, the traditional open repair is most commonly used despite the risk of re-rupture or post-operative infections, which in turn can impair the blood flow to the Achilles tendon. Therefore, minimally invasive methods to overcome these complications have been studied with excellent outcomes.

Various minimally invasive repair techniques have been performed for acute Achilles tendon rupture. Despite this, it is difficult to use these techniques in common practice because of the necessity of special instruments. We propose a novel minimal invasive technique using sponge holding forceps, which are commonly used in the operating room for the acute Achilles tendon rupture.

The purpose of this study is to analyze, durability of motor effort after finishing rehabilitation program and the influence from the isotonic lumbar region extension exercise after an operation according to the different operation way in invasive degrees. We selected randomly 80 patients who have no complication and musculoskeletal system diseases with finishing the 12 weeks' rehabilitation program after getting laser discectomy, but fail to conservative treatment, about Lumbar HNP, and divided into minimal invasive groups 38 and invasive groups 42 for study. As the results, in minimal invasive group, after finishing cure and 6 months later, the degree of hold muscle of women is much better than that of men. but in Invasive group, that of men is better than that of women, in case of women, the $0^{\circ}$ and $72^{\circ}$ in lumbar flexion angle have weaken or no improvement than before beginning exercise. and muscle force in $72^{\circ}$ in lumbar flexion angle increased to all men and women than before beginning exercise in Minimal invasive group. but in invasive group. it decreased. When analyze the lapsed time in Minimal invasive group, the groups who start the exercise within 3 months are better than the groups who start the exercise above 3 months after an operation the hold muscle degree all angles after finishing cure and 6 months later. Meanwhile, in invasive group, the groups who start the exercise within 3 months are better than the groups who start the exercise above 3 months after an operation about the hold muscle degree in 36-72 of lumbar flexion angle but 0-36 are not good after finishing cure and 6 months later. When analyze BMI in Minimal invasive group, the normal groups are better than the overweight groups about hold muscle degree in all angles after finishing cure and 6 months later.

Background Hyaluronic acid fillers can be manufactured using various processes. They have multiple properties, including their concentration, degree of modification, and rheological data. Cohesion is one such property to evaluate gel integrity; however, there is no standardized method for calculating this parameter. This study aimed to evaluate different tests for calculating hyaluronic acid cohesion and discuss the importance of hyaluronic acid cohesion as a consideration when selecting fillers. Methods The cohesion levels of five different hyaluronic acid fillers with different rheological properties were evaluated and compared using the drop weight, compression, tack, and dispersion time tests. Results The cohesion tests yielded different results in the samples. Samples 2 and 4 showed approximately two times the number of droplets when compared with Sample 5 in drop weight test. Samples 1, 2, 3, and 4 were superior to Sample 5 in tack test. Samples 1, 2, and 3 showed cohesive appearances at 95 seconds in most cases in dispersion test. Rheological test results did not reflect the measures of cohesion. Conclusion Although there are no definite standardized tests to evaluate the cohesion of hyaluronic acid fillers, our proposed tests showed similar results for different hyaluronic acid filler products. Further studies are needed to evaluate the cohesion of hyaluronic acid fillers and determine the clinical use of this distinguishing characteristic for clinicians selecting the product of choice. Level of evidence statement: These data are Level IV evidence.
