Laparoscopic surgery is a well-established alternative to open surgery across disciplines. However, in veterinary medicine, laparoscopic surgery in dogs was rarely reported because of small abdominal size for multiple ports insertion. The concept of single-incision laparoscopic surgery (SILS) is to perform the entire laparoscopic operation through a single incision rather than conventional multiple small skin incisions. Indirect evidence of potential benefits of SILS, decreases operative morbidity related to reduction in port size, already exists. Therefore, this study was performed to evaluate the safety and feasibility of the modified form of SILS using flexible endoscope in Cholecystectomy before clinical adoption. A 2 cm single periumbilical incision was performed, and flexible endoscope was introduced into the abdominal cavity. A laparoscopic grasper was inserted into the abdominal cavity for the traction of gall bladder. Cystic duct and artery were ligated by 5 mm Hem-o-lok$^{(R)}$. Then, gall bladder was dissected and resected from the liver with 5 mm Autonomy Laparo-Angle Maryland dissector and endoscopic needle knife. Resected gall bladder was wrapped by using specimen pouch and was retrieved through abdominal incision from the cavity. All three gall bladders were successfully removed. Hematological changes were not observed during examination periods. No leakage sign was identified at necropsy. The flexible endoscope, as distinct from conventional rigid laparoscope, allows the visualization from various angles and the wide range of motion, result in less crowding.

심폐바이패스를 사용하지 않고 심장박동 상태에서 시행하는 관상동맥 우회수술은 심 비대와 좌심실 기능저하가 동반된 협증심 환자에서는 심장 뒤쪽에 위치한 관상동맥에 대한 접근이 어렵고 수술 중 혈역학적으로 불안정하여 시행하기에 어려운 경우가 많다. 우심실 보조장치 하의 심장박동 상태에서 시행하는 관상동맥 우회수술은 대동맥의 삽관을 피하고, 심폐바이패스의 합병증을 줄일 수 있으며, 심장 뒤쪽에 위치한 혈관의 문합시에도 안정된 혈역학적 상태를 유지 할 수 있어 고위험군 환자에게 도움을 줄 수 있다. 좌심실 기능저하와 심 비대가 동반된 환자에서 우심실 보조장치 하의 심장박동 상태에서 시행한 관상동맥 우회수술을 2례 시행하여 좋은 결과를 얻어 보고하고자 한다.

More than 120 surgical methods for the correction of hallux valgus deformities have been reported. For the correction of moderate to severe hallux valgus deformities with aesthetic demands, minimally invasive surgery at the proximal area can be considered. This paper reports a case of moderate hallux valgus deformity treated by a minimally invasive proximal transverse metatarsal osteotomy followed by intramedullary plate fixation.

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.

A postoperative hallux varus deformity is a dreaded complication of hallux valgus surgery. Several surgical options have been introduced to overcome this problem. This paper reports an uncommon case of a 68-year-old female patient who presented with a postoperative hallux varus deformity combined with a rupture of the flexor hallucis longus (FHL) tendon. She was treated successfully by a minimally invasive correctional osteotomy with open tenorrhaphy. With experience in treating this complicated case, it was noted that FHL could be transected during the trans-articular adductor tenotomy. Hence, extra caution is needed when the degree of hallux valgus deformity is excessive. To the best of the author's knowledge, correctional valgization osteotomy for a postoperative hallux varus deformity in a minimally invasive manner has not been reported. This case report is expected to benefit surgeons and their patients with severe hallux valgus deformity.

A 65-year-old patient who underwent total thyroidectomy 10 years ago was suspected of having a parathyroid adenoma, and minimally invasive parathyroidectomy was planned. Preoperative ultrasonography(USG) and 99mTc MIBI scan indicated a left lower parathyroid lesion. In the first operation, intraoperative parathyroid hormone monitoring (IOPTH) was not possible due to hospital circumstances. Although no adenomatous lesion was found in the expected surgical field, surgery was completed after removing lesions around the left lower parathyroid gland. However, post-surgery, parathyroid hormone did not decrease at all, so a second operation was performed with IOPTH preparation. In the second operation, intraoperative ultrasonography was performed, and a suspected adenoma lesion was removed from the left upper lesion. He has been under follow-up for 3 years without complications. Surgeon-peformed intraoperative USG and preoperative scintigraphy had advantages in determining the localization of parathyroid lesion even withiout IOPTH.

Purpose: To analyze the outcome of distal tibia fracture treated with the Distal Tibia LCP with combination of interfragmentary screw. Materials and Methods: Between January 2008 and March 2012, data of 34 patients with fracture of distal tibia treated with the Distal Tibia LCP with or without combination of interfragmentary screws were reviewed. There were 17 males and 17 females with an average age of 51.8 years (range, 18~77 years). Radiographic union time and time from surgery until ability to full weight bearing were measured and compared. Callus index was measured as quotient of callus thickness and diameter of corticalis both in AP and sagittal direction. Results: 12 fractures were treated with interfragmentary screws and 22 fractures were treated with bridging plate alone. In interfragmentary fixation group, time to full weight bearing was 14 weeks versus 15.75 weeks without screw. Callus index at bearing was not significantly lesser in patients with screw compated with those without, but callus index difference at posterative 4weeks was sigficant. Radiologic union time was 11.3 weeks in interfragmentary fixation group and 12.58 weeks without screw. Conclusion: The osteosynthesis with the Distal tibia LCP with combination of interfragmentary screw seems to be more stable in postoperative 4weeks than Distal tibia LCP alone, expecting to earlier ROM exercise and rehabilitation.

The incidence of rotator cuff tear is increasing rapidly due to the aging of the population and the advancement of radiological diagnosis, and so on. Recently, arthroscopic rotator cuff repair is common way of surgery, and the surgical outcome is comparable to open rotator cuff repair. Arthroscopic repair is one of the minimally invasive procedures itself and may have additional benefits of postoperative pain reduction and early functional recovery. Recently, there has been increasing interest in various methods for improving the functional recovery of patients after arthroscopic shoulder surgery. Various protocols of functional recovery after arthroscopic shoulder surgery are classified by the postoperative period, and they are being studied actively and improved at each stage. On the other hand, there are a range of methods according to the postoperative period, rehabilitation stage, characteristics of individual patients, degree of rotator cuff tear, and underlying disease. Therefore, for functional recovery after arthroscopic rotator cuff repair, it is essential to establish proper regimens for functional recovery.

Background: The significance of MIDCAB is emerging topics recently as OPCAB is going to be universalized, and long-term outcome of bypass graft surgery was proved to be more excellent than balloon dilation or stent insertion. We report our MIDCAB results in 73 patients in the last three years. Material and Method: Retrospective analysis of medical records was done from November 1, 2000 through November 31, 2003. There were 47 males and 26 females ranging in age from 31 years to 79 years (average $61.3\pm9.8$ years). Observation periods after operative procedures were 10 to 1238 days (average $763\pm319.8$ days). Left longitudinal parasternal incision as a standard procedure was done to approach the heart after dissection of the left internal thoracic artery by partial or total resection of 3rd to 5th ribs. Result: Of those patients, 46 patients were transferred to ICU after extubation at operation room and 58 patients were extubated within 3 hours after operation. Average ICU staying periods was $26.8\pm11.5$ hours. Follow-up angiography during admission was done in 36 patients and showed 100% patency. Only one patient died on the 10$^{th}$ post operative day because of sudden CVA. Complications included wound problems in 4 patients, and constructing pericardial window using thoracoscopy due to continuous pericardial effusion in 1. Permanent pacemaker was inserted in one patient owing to sick sinus syndrome. In one patient with recurrence of angina 8 months after operation, stenosis at anastomic site was found and improved with balloon dilatation. Conclusion: We were satisfied with our results of MIDCAB in single and multi-vessel coronary artery disease. These results have made the cardiologists tried to operate positively and we expect widening operative indications including hybrid revascularization.
