Benign lung tumors compose a heterogeneous group of solid growths that present variations in clinical features, depending on whether the origin is within the bronchus on lung parenchyma or from visceral pleura. Benign tumors of the lung are relatively uncommon, and series are to be found in the literature and the classification of benign tumors of the lung continues to be controversial because of disagreement concerning the origin and prognosis of many common lesions. We adopt Liebows original classification but excluded bronchial adenoma which no longer considered as benign tumor and added pulmonary A-V fistula and congenital cystic adenomatoid malformation. We analyzed 61 cases of benign tumors which were composed of 16 original Korean cases and 45 cases which were reported on journal of Thoracic & Cardiovascular Surgery. The results were. [1] Incidence; Of 61 cases, chondromatous hamartoma was 2 cases [41 %], congenital cystic adenomatoid malformation 10 cases [16.4 %], pulmonary A-V fistula 5 cases [8.1 %], sclerosing hemangioma 4 cases [6.5 %], teratoma, plasma cell granuloma & mesothelioma were 3 cases [4.9%], Castlemans disease 2 cases [3.3%], and mucous gland adenoma, paraganglioma, and leiomyoma 1 case [1.6 %]. [2] Age & Sex distribution; Male 30 cases and female 31 cases. Mean age was 31.4 years old. [3] Main symptom; was coughing, 32.8%, and no symptom, 24.6%. [4] Sixty eight percentage of chest film showed mass density, and 4 cases showed calcification, 2 cases had lobulation. [5] Size of mass was large and multiple mass was 2 cases. Endobronchial tumors were 9 cases, 14.9 %. [6] Three cases of endobronchial tumor were preoperatively diagnosed by bronchoscopy and 2 cases of pulmonary A-V fistula were diagnosed by pulmonary arteriography. [7] Seven cases, 11.5%, had associating diseases such as bronchogenic cyst, thymic cyst, Schwannoma, situs inversus, bronchiectasis and bronchogenic carcinoma. [8] Minor resection such as excision 8i: wedge resection were 15 cases, 26.2 %, and 6 cases, 75.4 %, of lobectomy were performed including 5 cases of pneumonectomy 5 cases had. [9] Postoperative complications; One case, 1.6 %, expired due to respiratory insufficiency. Two cases had re-operation due to bleeding and hemoptysis.

The spontaneous pneumothorax occurs subsequent to a disruption in the continuity of the visceral pleura with escape of free air into the pleural space included primary & secondary pneumothorax that is unrelated to identifiable etiologies such as trauma. In. the 33 year period 1960 to 1993, the 230 cases of open thoracotomy were carried out for definitive treatment of spontaneous pneumothorax, at the Dept. of Thoracic & Cardiovascular Surgery, National Medical Center, Seoul, Korea. There were 193 men & 37 women. They ranged in age from 15 years old to 72 years old. The lesion site was on the right side in 117 and on the left in 97, the 16 cases were in bilateral lesions.Surgical indications included recurrence in 98 cases, persistent air leak in 68 cases, nonexpansion of the lung 37 cases, roentgenologically apparent bullae & blebs in 23 cases, bilateral lesions in 16 cases,combined hemothorax & prevent for recurrence in each 2 cases. The types of operation were bullectomy in 207 cases, wedge resection in 13 cases, decortication & B.P.F. closure in 6 cases,lobectomy in 2 cases, pneumonectomy, plication in each I case. The post operative complication developed in 18 cases[7.8 %], there was I case of death due to sepsis. We believed that open thoracotomy with resection or obliteration of blebs & pleurodes is provided the best protection against recurrence.

Purpose: This study aimed to identify the feasibility of the maximum standardized uptake value (SUVmax) on baseline 18F-fluorodeoxyglucose positron emission tomography-computed tomography (FDG PET/CT) as a predictive factor for prognosis in early stage primary lung cancer treated with stereotactic body radiotherapy (SBRT). Materials and Methods: Twenty-seven T1-3N0M0 primary lung cancer patients treated with curative SBRT between 2010 and 2018 were retrospectively evaluated. Four patients (14.8%) treated with SBRT to address residual tumor after wedge resection and one patient (3.7%) with local recurrence after resection were included. The SUVmax at baseline PET/CT was assessed to determine its relationship with prognosis after SBRT. Patients were divided into two groups based on maximum SUVmax on pre-treatment FDG PET/CT, estimated by receiver operating characteristic curve. Results: The median follow-up period was 17.7 months (range, 2.3 to 60.0 months). The actuarial 2-year local control, progression-free survival (PFS), and overall survival were 80.4%, 66.0%, and 78.2%, respectively. With regard to failure patterns, 5 patients exhibited local failure (in-field failure, 18.5%), 1 (3.7%) experienced regional nodal relapse, and other 2 (7.4%) developed distant failure. SUVmax was significantly correlated with progression (p = 0.08, optimal cut-off point SUVmax > 5.1). PFS was significantly influenced by pretreatment SUVmax (SUVmax > 5.1 vs. SUVmax ≤ 5.1; p = 0.012) and T stage (T1 vs. T2-3; p = 0.012). Conclusion: SUVmax at pre-treatment FDG PET/CT demonstrated a predictive value for PFS after SBRT for lung cancer.

Pulmonary resectlon has evolved as the treatment of choice in certain pulmonary tuberculosis cases. This study represents an analysis of 640 cases of pulmonary resections between March, 1953 and August, 1966 and 370 cases of 13 years follow-up results at the 36th Army Hospital. 1] The ages ranged from 20 to 45 years and all cases were males. 2] The extent of disease revealed 116 Far advanced, 472 Moderate advanced and 52 Minimal Cases. 3] The extent of resections were 373 lobectomies, 130 segmental resections, 58 pneumonectomies,25 multlple lobectomies, 25 lobectomies with thoracoplasties, 22 lobectomies with segmental resections, and 7 wedge resections. 4] The postoperative complications occurred in 71 cases[11.09 percent]. Of these complications,bronchopleural fistula occurred in 13 cases [2.03 percent]. 5] The early operative mortality within 24 hours was 2.0 percent and late mortality within 6 months was 1.4 percent, a total mortality from all causes of 3.4 percent: 15.5 percent following pneumonectomy, 2.1 percent following lobectomy, 1.5 percent following segmental resectlon. 6] All 370 patients were followed for periods ranging from 6 months to 5 years and 5 years to 13 years. Of these former group of 241 patients, 73.3 percent of the cases had returned to full active llfe and remained well, while 15.4 percent were still under treatment. Of these latter group of 129 patients, 76.0 percent of the cases were well and 4.7 percent were still under treatment. 7] In the follow-up results according to extent of disease, the cure rate was greatest in cases of minimal group and lowest in cases of far advanced group. 8] In the results by extent of resection, the cure rate was greatest in cases of lobectomy group. 9] Through the all follow-up periods, 11 patents [3.0 percent] were died. Of these, 3 were suicide and 8 were unknown causes.

The current, retrospective study aimed to assess the short-term prognosis and postoperative complications associated with the surgical correction of elongated soft palate using harmonic scalpel and to compare the postoperative complications associated with the application of harmonic scalpel and traditional surgery using Metzenbaum scissors. Harmonic scalpel was used to perform staphylectomy in 21 dogs. A total of ten dogs underwent sacculectomy; six dogs with harmonic scalpel and four dogs using Metzenbaum scissors. Stenotic nares were corrected by wedge resection. Postoperative complications were recorded through monitoring and radiographic examinations. Telephone interviews were conducted on the first, third, and seventh day after discharge and continued until the resolution of postoperative complications. Postoperative edema at the surgical site was identified and mitigated within a day or two. Snoring and dyspnea improved dramatically in the group that underwent staphylectomy alone. Moreover, three dogs presented with postoperative gastrointestinal complications, especially retching. The symptoms persisted for seven days and ten days in two dogs that underwent sacculectomy with harmonic scalpel and for two days in one dog that underwent sacculectomy with Metzenbaum scissors. The clinical signs and symptoms of brachycephalic syndrome disappeared without recurrence. Harmonic scalpel provides a hemostatic effect during staphylectomy, is convenient, and does not cause postoperative complications. Conversely, the use of harmonic scalpel during sacculectomy necessitated a longer period for the resolution of complications without any significant hemostatic efficacy, compared to traditional surgery.

Pulmonary hamartoma is often incidental, asymptomatic finding on routine chest roentgenogram. It has been considered a congenital malformation. Since the original description by Albrecht in 1908, it has been classified into two types, a small, fibrocartilaginous mass in adults, and a cystic lobar mass in infants. We experienced two cases of pulmonary hamartoma which proved to be the adult form of hamartoma. One was located in left upper lobe of a 58 year old male patient, the other was located in the perihilar region of the right middle lobe of a 38 year old male patient. The former case was treated by wedge resection: the latter by right middle lobectomy and the postoperative courses of both cases were very good and without complication.

Gastric glomus tumor is a rare mesenchymal tumor that originates from modified smooth muscle cells of the glomus body. Glomus tumors are commonly observed in peripheral soft tissue, such as dennis or subungal region, but rarely in the gastrointestinal tract. A 39-year-old woman was admitted due to epigastric soreness. Upper gastrointestinal endoscopy revealed a subepithelial mass measuring 3.5 cm with central ulceration at the lesser curvature-posterior wall of the antrum. Characteristically, contrast enhanced abdominal computed tomography scan demonstrated high enhancement of the submucosal mass up to the same level of the abdominal aorta in the arterial phase; this enhancement persisted to delayed phase. Due to the risk of bleeding and malignancy, wedge resection of the submucosal tumor was performed. Histologic findings were compatible with a glomus tumor.
