Background: Conventional thoracoscopic thoracic sympathectomy or sympathicotomy is an effective method in treating localized hyperhidrosis; however, this may result in a postoperatively embarrassing compensatory hyperhidrosis or facial anhidrosis in the treatment of palmar hyperhidrosis. We modified the conventional sympathicotomy by limiting the extent of nerve transection. The purpose of this study was to assess the result of the limited thoracoscopic sympathetic nerve transection in hyperhidrosis. Material and Method: From May to August 1998, 17 patients underwent limited transection of the sympathetic nerve. For 9 patients with facial hyperhidrosis, we transected only the interganglionic fiber between the first and the second ganglion, whereas the conventional method cuts two interganglionic fibers. Eight patients with palmar hyperhidrosis underwent limited transection of the interganglionic fiber between the second and third ganglion. Result: Sixteen patients had improved symptom postoperatively. There was a recurred facial sweating in 1 patient 1 month after the operation. Among the 9 facial hyperhidrosis patients, postoperative compensatory hyperhidrosis was severe in 4, moderate in 4 and minimal in 1. But in 8 cases of palmar hyperhidrosis compensatory hyperhidrosis was moderate in 3, and minimal in 1, none in 4. Facial sweating was not disturbed postoperatively in all of the palmar hyperhidrosis patients. Conclusion: Limited sympathetic nerve transection is a practical and less invasive method for the treatment of localized hyperhidrosis and may reduce the incidence of compensatory truncal hyperhidrosis and facial anhidrosis in case of palmar hyperhidrosis.
Since Endoscopic ultrasound (EUS) was introduced in the 1980s, EUS has evolved from a diagnostic tool to a therapeutic modality for patients with pancreatic neoplasms. Traditionally, treatment policy of pancreatic benign neoplasms (PBN) has been a dichotomous approach to observation or surgery. However, EUS guided treatment provides an alternative option with minimally invasiveness for patients with PBN. This review aimed to provide the role of EUS guided treatment for PBN.

Oral mucocele is a common exophytic lesion resulting from the accumulation of saliva due to pathological changes in the minor salivary glands. It is typically asymptomatic and painless and characterized by semipermeable, fluctuant nodules. General treatment methods for mucocele include surgical excision, marsupialization, cryosurgery, and steroid injection. This case report presents the treatment of oral mucocele using micro-marsupialization and a tying method as minimally invasive techniques rather than surgical treatment. Based on this case report, it is suggested that micro-marsupialization and the tying method can be used as alternative methods for the treatment of oral mucocele infants and children with behavioral control problems.

Purpose : Although local recurrence rates of stomach cancer after radiocal surgery have been reported in the range of $30-70\%$, the role of postoperative adjuvant therapy has not been established. We report the result of radiotherapy in resected stomach cancer with positive surgical margin to elucidate the role of postoperative radiotherapy. Materials and Methods : From June 1991 to August 1996, twenty five patients with positive surgical margins after radical gastrectomy were treated with postoperative radiotherapy and chemotherapy. Median dose of radiation was 55.8Gy and the range was 44.6-59.4Gy. Second cycle of chemotherapy was delivered concurrently with radiation and total number of six cycles were delivered. Twenty three had adenocarcinoma and the other two had leiornyosarcoma. The numbers of patients with stage I B, II, III A, III B, and IV were 1, 2, 11, 10 and 1 respectively. Positive margins at distal end of the stomach were in 17 patients and proximal in 5. The other three patients had positive margin at the sites of adjacent organ invasion Minimum and median follow-up periods were 12 months and 18 months, respectively, Results : Twenty-four of 25 patients received prescribed radiation dose and RTOG grade 3 toxicity of UGI tract was observed in 3, all of which were weight loss more than $15\%$ of their pretreatment weight. But hematemesis. melena, intestinal obstruction or grade 4 toxicity were not found. Locoregional failure within the radiation field was observed in 7 patients, and distant metastasis in 10 patients. Sites of locoregional recurrences involve anastomosis/remnant stomach in 3, tumor bed/duodenal stump in 3, regional lymph node in 1 patient Peritoneal seeding occurred in 6, liver metastases months and median disease free survival time was 26 months. Stages andradiation dose were not significant prognostic factors for locoregional in 2, and distant nodes in 2 patients. Four year disease specificsurvival rate was $40\%$ and disease free survival was $48\%$. Median survival was 35 failures. Conculsion : Although all patients in this study had positive surgical margins, locoregional failure rate was $28\%$, and 4 year disease specific survival rate was $40\%$. Considering small number of patients and relatively short follow-up period, it is not certain that postoperative radiotherapy lowered locoregional recurrences. but we could find a Possibility of the role of postoperative radiotherapy in Patients with high risk factors.
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.

Purpose: Primary bone tumors of hindfoot are uncommon compared with other locations, and there have been few large-group studies. This study was designed to analyze the characteristics and the clinical results of the primary bone tumors of hindfoot. Materials and Methods: Forty five cases in 44 patients who have been diagnosed from 1989 to 2011 were reviewed. The minimum follow-up period was 1 year. We retrospectively reviewed the medical records and images. Results: Twenty six cases were male and 18 cases were female. Mean follow-up period was 33.1 months and mean age was 25.1 years. Forty four cases were benign and 1 case was malignant. Thirty six cases occurred in calcaneus and 9 cases were in talus. The most common benign bone tumor was simple bone cyst (20 cases), followed by intraosseous lipoma (12 cases), and chondroblastoma (4 cases). In calcaneus, there were 18 cases of simple bone cyst, and 12 cases of intrasosseous lipoma. In talus, there were 3 cases of chondroblastoma, 2 cases of simple bone cyst, and 2 cases of intraossesous ganglion. Many patients with hindfoot bone tumors presented with pain, but some were found accidentally. Patients received surgical procedures, such as curettage and bone graft, open reduction and internal fixation, tumor resection, and below knee amputation. Conclusion: Primary bone tumors of hindfoot are rare and can be misdiagnosed as ankle sprain or contusion. Although most are benign, malignant tumors cannot be ruled out, so early diagnosis and appropriate treatment is important.

Background: A chest computed-tomography has become more prevalent so that it is more common to detect small sized pulmonary nodules that have not been found in previous simple chest x-ray. If those detected nodules are undersized or located in pulmonary parenchyma, it is difficult to accomplish a biopsy since it is vulnerable to explore them either grossly or digitally. Thus, in our hospital, a thoracoscopic pulmonary wedge resection was performed after locating a lesion by means of hook wire with CT-guided. Material and Method: 31 patients (17 males and 14 female patients) from December in 2006 to June in 2010 became our subjects; their 34 pulmonary nodules were subjected to the thoracoscopic pulmonary wedge resection after locating a lesion by means of hook wire with CT-guided. Also we analyzed a possibility of hook wire dislocation, a frequency of conversion to open thoracotomy, time consumed to operation after location of a lesion, operation time, post operation complication, and histological diagnosis of the lesion. Result: 12 of 34 cases were ground glass lesion, whereas 22 cases of them were solitary pulmonary lesion. The median value of the lesion was 8mm in size (range: 3 to 23 mm), while the median value was 12.5 mm in depth (range: 1 to 34 mm). The median value of time consumed from location of the lesion to anesthetic induction was 86.5 minutes (41~473 minutes); furthermore the mean value of operation time was 103 minutes (25~345 minutes). Intrathoracic wire dislocation was found in one case, but a target lesion was successfully excised. Open thoracotomy was performed in four cases due to pleural adhesion. However, there was no case of conversion to open thoracotomy due to failure to detect a target lesion. In histological diagnosis, metastatic cancer were found in 15 cases, which were the most common, primary lung cancer were in 9 cases, non-specific inflammation were in 3 cases, tuberculosis inflammation were in 2 cases, lymph nodes were in 2 cases, active tuberculosis were in 1 case, atypical adenomatous hyperplasia was in 1 case and normal lung parenchymal finding was in 1 case, respectively. Conclusion: In our hospital, in order to accomplish a precise histological diagnosis of ground-glass lesion and pulmonary nodules in lung parenchyma, location of pulmonary nodules were exactly located with hook wire under chest computed-tomography, which was followed by lung biopsy. We concluded that this was an accurate, minimally invasive and valuable method to minimize the complications and increase of cost of medical service provided.

Purpose: We evaluated oncologic outcomes of chondrosarcomas and analyzed the disease-free survival rate of chondrosarcomas according to the various factors. Materials and Methods: We performed a retrospective study for the disease-free survival rate of 48 chondrosarcomas, 44 of which underwent surgical treatment and followed up more than 18 months since 1993, and in the remaining 4 cases, the patients died before 18 months after surgery. The vsariables were location, tumor volume, histologic grade, stage, age at presentation and treatment performed. The mean follow up period was 43.8 months (1-196 months). Results: The overall disease-free survival rate was 77.1% at mean 43.8 month follow up. The 5 year- and 10 year disease-free survival rates were 64% and 58% respectively. The histologic grade, stage, age at presentation revealed statistical significance on disease-free survival. All 9 patients treated with extended curettage for grade 1 central chondrosarcomas revealed disease-free survival with excellent functional outcome. Conclusion: The disease-free survival rate of chondrosarcomas mainly depended on histologic grade, stage and age at presentation. Local recurrence and distant metastasis also revealed statistically significant differences of disease-free survival rate. Comparing to wide resection, extended curettage for low-grade central chondrosarcomas in extremities were efficient methods with similar survival rate and less functional losses and complications.

Purpose: Interferon-${\alpha}2b$ using immunotherapy of malignant melanoma is known to increase the microscopic enemies that remain after surgical resection of the tumor to prevent recurrence, disease-free survival and overall survival. Authors in patients with malignant melanoma after surgical resection and high-dose interferon-${\alpha}$ immunotherapy treated group of disease-free survival and overall survival compared with the results of the treatment of immune therapy to a preliminary report. Materials and Methods: From February 2010 to October 2012 at our institution between being diagnosed with malignant melanoma after surgical immunotherapy treated patients were analyzed. Patients was evaluated using the stage AJCC stage IIA 3 cases, IIB 1 cases, IV 1 were as follows. Follow-up period of at least 7 months, and a maximum of 32 months. As maintenance therapy after the first induction therapy group underwent immunotherapy interferon-${\alpha}$ of body-surface area per 200,000 IU five times in a week for 4 weeks sedentary and body surface area a total of 48 weeks per week to 100,000 IU three times subcutaneously. These patients for local recurrence and metastases, and distant metastasis were investigated disease-free survival was investigated. Results: Interferon-evaluation through follow-up chest computed tomography (CT) and positron emission computed tomography (PET CT) in patients who underwent the ${\alpha}$ immunotherapy results above both local recurrence and metastases without evidence of distant metastases. Conclusion: The high-dose ${\alpha}2b$ immunotherapy performed in patients to prevent the local recurrence of the tumor and metastasis to the current or future ultimate survival and disease-free survival improvement achieved is additional study and follow-up will be needed.
The use of laser in the treatment of soft tissue minimizes hemorrhage, provides better view of the operating field, and thereby minimizes operating time. Also, there will be far less post-operative swelling, pain and scar formation, and sterilizing effect are shown in some portions of the wound site. All these advantages of laser therapy contribute to its widespread use in the field of medicine and dentistry. Regarding such facts, we used CO2 laser of different watts in gingivectomy for white rats to compare initial healing process. For the control group, the least amount of output in performing gingivectomy(4watts) was offered, and for the experimental group, 6watts was given. Animals were sacrificed on the second, third days, 1 weeks, 2 weeks, and 3 weeks after operation, and their specimens were histologically analyzed. The following results were obtained: 1. Blood clot of small size was observed in both the control and experimental groups after two days, and no more thereafter. 2. In both the control and experimental groups, the inflammation zone size was the greatest after two days, and it decreased gradually to become almost invisble by the second week. The experimental group showed larger size of inflammation zone during second and third days: however, there was no difference after one week. 3. Granulation tissue in both the control and experimental groups showed gradual maturation with time, and by the second week, it was almost replaced by normal connective tissue. By the third week, complete healing pattern was observed. The experimental group showed larger granulation tissue than the control group until the third day, but there was no significant difference after one week. 4. In both the control and experimental groups, gingival epithelialization began on the second day. After one week, regeneration of rete peg and partial formation of junctional epithelium were observed: by the second week, keratinization of oral sulcular epithelium began, and it was completed by the third week.
