Background: Recently transilluminated powered phlebectomy was introduced and used as a method of surgical treatment for varicose vein in lower extremities. The advantage of transilluminated powered phlebectomy are minimal scar and good cosmetic effect. However, the disadvantages of transilluminated powered phlebectomy is that a high priced Trivex system must be used which increases the patient's expenses. Therefore, we performed a transilluminated powered phlebectomy using an existing arthroscopic equipment instead of Trivex system and observed the effect of treatment and efficiency of the treatment. Material and Method: From March, 2000 to February, 2003, 78 patients (113 limbs) underwent transilluminated powered phlebectomy with an arthroscopic equipment. Patient's disease history, the number of operative scars and complications were reviewed. Result: The operation was performed in 133 limbs of the 78 patients (34 men, 44 women) and the age of patients were ranged from 16 to 72 years with mean age of 41.8 years. Operative time ranged from 20 to 65 minutes (average 48.7 minutes) per limb. The number of operative scar per limb from 2 to 7 (average 4.9). Postoperative complications are transient ecchymosis (78 cases) that desappeared spontaneously, edema persisting longer than 3 weeks (6 cases), remnant varicose vein (4 cases), skin perforation during operative procedure (2 cases), and contact dermatitis due to compression stocking (4 cases) The mean hospitalization day was 3.09 days. Subjective mean satisfaction degree of operation by the patients using a visual analogue scale was 92.6%. Conclusion: Our findings demonstrated that transilluminated powered phleectomy using arthroscopic equipment was possible and had good cosmetic results with acceptable complications.

Local control is the important prognostic factor in cancer treatment because local control decrease the relative risk of metastatic spread and inclose distant metastasis free suwival. IORT is the modality which could increase local control without incressing complication, combined with curative operation. Eventhough we could achieve significant deacreased local failure by IORT and curative resection, it should not be committed as a main treatment modality without proving acceptable complications. Therapeutic Radiology Department of Yeungnam University Medical Center have tried 58 IORT from June 15, 1988, and performed 53 IORT En patients with gastric cancer. No local failure has been reported by regular follow up so far. Nine cases ($17\%$) of treatment related complicaiton were reported including intestinal obstrution, hemorrhage, sepsis, and bone marrow depression. These complications could be comparable to Jo's $25.2\%$ (chemotherapy + operation), Kim's $18\%$ (chemotherapy only in inoperable patients), because our treatment regimen is consisted of IORT (1500 cGy), external irradiation (--4500 cGy) and extensive chemotherapy(FAM, 5FU + MMC, BACOP).

From September 1994 to October 1995, we are reporting clinical results of 67 patients whom underwent video-assisted trio rabic surgery(VATS). 1. They were diagnosed as spontaneous pneumothorax In )5, diffuse interstitial lung disease in 9, empyema in 7, hemothorax in 5, malignant pleural effusion in 3, hyperhidrosis in 3, foreign body in chest cavity in 2, mesothelioma in 1, miliary tuberculosis in 1 and organizing pneumonia in 12. In pneumothorax, bullectomy in 33 and open bellectoiny in 2 due to pleural adhesion was done Hemostasis in 5, irrigation in 7, foreign body removal in 2, talcum powder insufrlation in 3, sympathectomy 3 as done. Thoracoscopic biopsy watt done In 12 3. For pneumothorax, operation was indicated as recurrent pneumothorax in 18, persistent air leak in 12, visible bullae In chest X-ray in 5. 4 Thoracoscopic biopsy was done in 12. They were interstitial pulmonary fibrosis in 9, miliary tuberculosis in 1, mesothelioma in 1, and organizing pneumonia in 1 .Among interstitial pulmonary fibrosis, usual interstitial pneumonia were 2 and diffuse interstitial pneumonia were 7. 5. Wo complication was found in 6) patients among 67 patients. The complication was found in 4 patients (2 persistent air leak, 2 contralateral lung atelectasis). We concluded that VATS was safe and beneficial in reducing postoperative complication and the role of thoracic surgery will increase markefdly.

Although the formation of fistula between esophagus and adjacent organ is a known complication of the self-expanding esophageal stent, only a few cases of surgically treated bronchoesophageal fistula have been reported. Increasing application of endoscopic stent for benign esophageal strictures increases the chance for this type of delayed complication. We experienced a case of bronchoesophageal fistula caused by esophageal stent for which we performed fistulectomy and Ivor Lewis operation simultaneously. To the best of our knowledge, this is the first report on the successful surgical treatment of this complication in Korea.

Laryngeal framework surgery comprises medialization laryngoplasty and arytenoid adduction. Since their introduction in the 1970s, these procedures have become standard treatments for vocal fold paralysis and glottal incompetence. However, frequency of laryngeal framework surgery is conjectured to relatively decrease along with the introduction of injection laryngoplasty. In this manuscript, indications for laryngeal framework surgery were highlighted in contrast to those of injection laryngoplasty. The authors introduced the basic concepts and principles as well as surgical techniques of laryngeal framework surgery. Even though the incidence of major and/or minor complications after laryngeal framework surgery is not high, surgeons should be well aware of its possible complications and they should be familiar with tips and know-how to avoid or cope with complications.

Laryngomicrosurgery is common procedure applying to benign laryngeal lesion. Suspension of the laryngoscope is a vital component of Laryngomicrosurgery. Suspension laryngoscopy allows for bimanual surgery and a stable operating platform. Little information is known about oropharyngeal & vocal fold complications of suspension laryngoscopy. Because laryngomicrosurgery is dependent upon suspension laryngoscopy, surgeons should fully understand the risks of suspension laryngoscopy to properly educate and care for patients undergoing suspension laryngoscopy. That is problem to allow otolaryngologist is embarrassing, for voice restoration surgery are not satisfied with the results. The authors reviewed mechanical and phonological complications after laryngomicrosurgery.

Patients over 15 years of age who have undergone a surgical correction of congenital heart disease at Kyungpook University Hospital during the period of January 1990 through October 1994 have been reviewed . One hundred forty three, 22.4 % of 628 operations, which have repaired congenital heart diseases during this period were adult patients. There were 23 patients under 20 years of age, 58 between 20∼29 years, 34 between 30∼39 years, 18 between 40∼49 years, and 10 between 50∼59 years. The most common defects were atrial septal defects which accounted for 73 cases (51.1 %) and other common anomalies were ven- tricular septal defects (57 cases, 39.9 %), tetralogy of Falloffs(4 cases, 2.8%) in order of incidence. There were 10 non-fatal operative complications (6.9 %) but there was no operative mortality. This study shows the incidence of operable congenital heart diseases in adults and the fact that it could be corrected surgically with low mortality and morbidity.

Thoracic sympathectomy is the radical and definite treatment of palmar hyperhidrosis. From January 1992 to March 1997, 4 patients with recurrent hyperhidrosis underwent resympathectomy via VATS at the Department of General Thoracic and Cardiovacular Surgery, Young Dong Severance Hospital. There were 2 men and 2 women and mean age was 20.0 years. There were moderate to severe adhesions at previous resection site but no thoracotomies were performed. There was no sweating on palms in all cases and all patients were greatly 5,Btisfied with those results postoperatively. In conclusion, recurrent hyperhidrosis was successfully treated with resympathectomy via VATS. In order to prevent recurrence and minimize the postoperative complication, the proper localization of the 2nd sympathetic ganglion and the radical excision of anatomical variation including Kuntz fiber are needed.

Although current surgical techniques have reduced the incidence of malunion, it is still observed because of the complexity of the fracture or associated injuries. Osteotomy is needed when the amount of malunion is expected to result in an overload of cartilage and instability of the joint. Preoperative planning is essential when performing an osteotomy for malunion. Inadequate planning can result in serious complications, such as iatrogenic malalignment, intraoperative fracture, postoperative recurrence of deformity, or soft tissue injuries. In addition, a poor functional result can occur secondary to poor patient selection. This review article includes the surgical indications and planning to correct malunion. Various methods of corrective osteotomy are described according to the kinds of plane and fixation implants.
