Purpose: Breast implant ruptures and displacement are problematic complications after augmentation mammoplasty. The authors report a patient whose cohesive silicone gel implant ruptured and migrated into the pleural cavity after augmentation mammoplasty. Methods: A 23-year-old female had received augmentation mammoplasty at a local clinic a week before visiting our hospital. When the patient's doctor performed a breast massage on the sixth postoperative day, the left breast became flattened. The doctor suspected a breast implant rupture and performed revision surgery. The implant, however, was not found in the submuscular pocket and no definite chest wall defect was found in the operative field. The doctor suspected implant migration into the pleural cavity, and after inserting a new breast implant, the doctor referred the patient to our hospital for further evaluation. The patient's vital signs were stable and she showed no specific symptoms except mild, intermittent pain in the left chest. A CT scan revealed the ruptured implant in the left pleural cavity and passive atelectasis. Results: The intrapleurally migrated ruptured implant was removed by video-assisted thoracic surgery (VATS). There were no adhesions but there was mild inflammation of the pleura. No definite laceration of the pleura was found. The patient was discharged on the first day after the operation without any complications. Conclusion: Surgeons should be aware that breast implants can rupture anytime and the injury to the chest wall, which may displace the breast implant into the pleural cavity, can happen during submuscular pocket dissection and implant insertion.

Background: Major intraoperative hemorrhage reportedly predicts unfavorable survival outcomes following surgical resection for esophageal carcinoma (EC). However, the factors predicting the amount of blood lost during thoracoscopic esophagectomy have yet to be sufficiently studied. We sought to identify risk factors for excessive blood loss during video-assisted thoracoscopic surgery (VATS) for EC. Methods: Using simple and multiple linear regression models, we performed retrospective analyses of the associations between clinicopathological/surgical factors and estimated hemorrhagic volume in 168 consecutive patients who underwent VATS-type esophagectomy for EC. Results: The median blood loss amount was 225 mL (interquartile range, 126-380 mL). Abdominal laparotomy (p<0.001), thoracic duct resection (p=0.014), and division of the azygos arch (p<0.001) were significantly related to high volumes of blood loss. Body mass index and operative duration, as continuous variables, were also correlated positively with blood loss volume in simple linear regression. The multiple linear regression analysis identified prolonged operative duration (p<0.001), open laparotomy approach (p=0.003), azygos arch division (p=0.005), and high body mass index (p=0.014) as independent predictors of higher hemorrhage amounts during VATS esophagectomy. Conclusion: As well as body mass index, operation-related factors such as operative duration, open laparotomy, and division of the azygos arch were independently predictive of estimated blood loss during VATS esophagectomy for EC. Laparoscopic abdominal procedures and azygos arch preservation might be minimally invasive options that would potentially reduce intraoperative hemorrhage, although oncological radicality remains an important consideration.

Background: Pleural symphysis is regarded as an important treatment option in reducing recurrence rates after surgical treatment of spontaneous pneumothorax. However, there is much debate over the best method for achieving pleural symphysis. We retrospectively compared apical pleurectomy (AP) with mechanical pleural abrasion (MPA). Material and Method: Between January 2000 and December 2007, 83 patients underwent video-assisted thoracoscopic surgery (VATS) for spontaneous pneumothorax. In addition to wedge resection of bullae, MPA was performed in 21 patients (group A) and AP in 62 patients (group B). Result: There were no significant differences in age, gender and site of pneumothorax between the two groups. Operative time was $97{\pm}44$ minutes in group A and $77{\pm}18$ minutes in group B (p>0.05). The mean amount of pleural drainage through the chest tube on the first postoperative day was $156{\pm}87 cc$ in group A and $147{\pm}87 cc$ in group B (p>0.05). There was no mortality or significant morbidity in all patients with the exception of reoperation for bleeding in two patients in group B. In the postoperative course, there were no statistical differences between the two groups in the rate of residual air space, air leak and indwelling time of chest tube, and hospital stay. Mean follow up time was $31.7{\pm}25.3$ months, and the recurrence rate of pneumothorax was 9.5% (2/21) in group A and 6.5% (4/62) in group B, without statistical significance. Conclusion: AP was no more advantageous than MPA in terms of operative time, postoperative course and prevention of recurrent pneumothorax. Therefore, complete resection of bullae and existence of residual bullae are more important factors in reducing the incidence of recurrent pneumothorax than pleural symphysis.

Background: This study was aimed at analyzing the preoperative conditions post-operative results indication and methods of surgical closure of patent ducturs arterio년 in prematures low birth weight infants and neonates. Patients and Methods: We retro-spectively studied two groups of patients (prematures group and neonates group) who underwent surgical closure of the patent ductus arteriosus between March 1995 and June 1998. Results: The premature group consisted of 9 patients(3 males and 6 females) Their mean gestational period was 30.7 weeks(ranging from 26 weeks to 33 weeks) mean age 27.8 days(11 days to 55 days) and mean body weight 1.56 kg. Prominent preoperative symptoms were dependency on mechanical ventilation generalized edema and hepatomegaly. We performed PDA ligation via thoracotomy in all premature patients. The neonate group consisted of 16 patients and their mean body weight was 3.75 kg. Major symptoms of this group was tachypnea and intercostal retraction resistant to medical treatment. We performed video-assisted PDA clipping to them all. There were no postoperative complications or operation-related mortality in both groups. Comparing the ratio of size of PDA(mm)/body weight(kg) the ratio of premature group (ligation through thoracotomy) was higher than that of neonate group ( video-assisted clipping) that is 3,89:1.21(p=0.03) Conclusion : We conclude that the surgical closure of PDA can be a safe method of treatment for prematures low birth weight infants and neonates with compromised general conditions. Choice of surgical technique depends on the surgeon's preference but there was a tend-ency to choose the ligation method through thoracotomy for patients with small body weight and large PDA.

Pulmonary alveolar proteinosis (PAP) is a rare disease in children characterized by intra-alveolar accumulation of surfactant proteins, which severely reduces gaseous exchange. Whole lung lavage (WLL) is the preferred technique for the treatment of severe PAP. Herein, we present a pediatric case of PAP treated with WLL. An 11-year-old boy was admitted with the chief complaint of a dry cough lasting 6 months. He developed symptoms of dyspnea on exertion and had difficulty in climbing stairs. He was ultimately diagnosed with PAP through video-assisted thoracoscopic lung biopsy. As first-line of treatment for PAP, he underwent therapeutic WLL for each of his lungs on separate days. After a brief recovery, his symptoms gradually worsened; therefore, he underwent a second WLL. This is the first pediatric case of PAP relapse despite successful WLL in Korea.

Video-assisted thoracoscopic surgery (VATS) for decortication or debridement in the management of empyema thoracis has increased the available treatment options but requires validation. We present and evaluate our technique and experience with thoracoscopic management of pleural empyema, irrespective of chronicity. Material and Method : VATS debridement or decortication was performed with endoscopic shaver system in 40 consecutive patients presented with pleural space infections. A retrospective review was performed and the effect of this technique on perioperative outcome was assessed. Result : VATS evacuation of infected pleural fluid and decortication was successfully performed in 35 of 40 patients. The mean duration of preoperative symptoms before referral was 23$\pm$1.8 days. The mean duration of hospitalization before transfer was 13.5$\pm$1.5 days. Blood loss was 250 to 200 mL. Intercostal drainage was required for 5$\pm$3 days. The postoperative hospital stay was 5 $\pm$0.7 days. There were no operative mortalities. Conclusion : Video-assisted evacuation of infected pleural fluid and decortication is an effective modality in the management of the fibropurulent stage of empyema. An organized empyema should be approached thoracosco-pically, but may require open decortication.

We hereby report a case on bronchogenic cyst which is initially non-infected, then becomes infected after bronchoscopic ultrasound (US)-guided transesophageal fine-needle aspiration (FNA). The non-infected bronchogenic cyst appears to be filled with relatively echogenic materials on US, and the aspirate is a whitish jelly-like fluid. Upon contrast-enhanced MRI of the infected bronchogenic cyst, a T1-weighted image shows low signal intensity and a T2-weighted image shows high signal intensity, with no enhancements of the cyst contents, but enhancements of the thickened cystic wall. The patient then undergo video-assisted thoracic surgery 14 days after the FNA. The cystic mass is known to be completely removed, and the aspirate is yellowish and purulent. To understand the image findings that pertain to the gross appearance of the cyst contents will help to diagnose bronchogenic cysts in the future.

Background: The purpose of this study was to identify factors associated with recurrent pneumothorax after wedge resection in primary spontaneous pneumothorax in our hospital. Material and Method: Two hundred thirty-five consecutive patient (98% males; mean age, $23.9{\pm}4.5$ years) who had undergone video-assisted thoracoscopic surgery (VATS) were reviewed retrospectively. The two groups were divided as follows: group A, non-recurrent patients (225 patients [96%]); and group B, recurrent group (10 patients [4%]); the risk factors were compared between the two groups. The single and multiple factors that influenced the recurrence rate were analyzed using Cox's proportional hazard model. Result: There were no significant differences between the recurrent and non-recurrent groups in terms of gender, smoking, site of recurrence, degree of collapse, operative time, and number or weight of resected bullae. The recurrence rate was significantly more common in the following: younger ages, increased height/weight ratio, longer initial air leakage period, and shorter duration of chest drainage. Early aggressive exercise (<30 days) of patients after wedge resection increased the tendency for recurrence. Conclusion: Thoracoscopic wedge resection does not have a higher recurrence rate than open thoracotomy. However, young age, height/weight ratio, continuous air, and duration of chest tube placement were risk factors for a recurrent pneumothorax.

Video assisted thoracic sympathectomy or sympathicotomy is a safe and effective therapy for the treatment of palmar hyperhidrosis with immediate symptomatic imporvement. However the degree of satisfaction may diminish with time due to cmpensatory sweating or excessive hand dryness. Therefore by comparing and assessing the degree of symptomatic improvement or compensatory sweating following sympathectomy or sympathicotomy at various levels we aim to determine the optimal level of sympathetic nerve block which will result in minimal side effects and maximal benefit. Material and Method: Among 194 patients having undergone video assisted thoracic sympathectomy or sympathicotomy between January 1996 and June 1999, 137 patients who responded to either telephone interview or questionnaire were included in the current study. The patients were divided into three groups. Group I(n=61) ; patients having undergone T2,3,4 sympathectomy group II(35) ; patients having undergone T2 sympathicotomy and group III(41) ; patients having undergone limited T2 sympathicotomy which consist of block of interganglionic neuronal fiber on the third rib. The parameters studied comprised of pre- and post-operative palmar temperature change treatment satisfaction the degree of compensatory sweating or discomfort from palmar dryness postoperative complication and changes in plantar sweating Result : There was no difference in age and sex among the groups and the mean postoperative elevation in palmar temperature was 21.59$^{\circ}C$ without any differences among the groups. Patients expressing satisfaction were 65.6%, 62.9% and 90.24% in groups I, II and III, respectively(p<0.05) Moderate to severe compensatory sweating was present in 65.6% 51.4%, and 24.39%, in group I, II, and III, respectively(p<0.05) Slight but comfortable amount of palmar humidness was expressed in decreasing order group III(41.6%) group I(24.6%) and group II(5.7%) (p<0.05) Ineffectiveness or recurrence was present in 5patients in group I(8.2%) 1 patient in group II(2.9%) and none in group III. With regards to plantar sweating decrease in sweating was expressed in 43 patients(31.4%) while similar degree of sweating in 61 patients(44.5%) and increase in sweating in another 33 patinets(24.1%) Conclusion : Limited T2 sympathicotomy resection of the lower interganglionic neuronal fiber of the second sympathetic ganglion on the third rib showed immediate effect in palmar hyperhidrosis and caused lesser compensatory sweating and hand dryness.

In patients with pleural adhesion, video-assisted thoracic surgery (VATS) has been regarded as a contra- indication. When such adhesions were found during a thoracoscopic trial, the thoracotomy proceeded with for fear of parenchymal Injury and bleeding. We had a question whether or not thoracoscopic surgery should be done in such pleural adhesions. Of the 226 consecutive thoracoscopic surgeries from Jul. 1992 through Sep. 1995, pleural adhesions were detected intraoperatively in 50 cases (22.1%): a detailed breakdown is as follows: pneumothorax (16 cases), pleural disease (15), benign pulmonary nodule(7), mediastinal mass(5), hyperhidrosis (2), diffuse parenchymal or interstitial lung disease (2), bronchiectasis(2), and primary lung cancer(1). We classified pleural adhesions according to their extent and severity. Extent is categorized as the involved area of the lung: degree 1, II, or III; severity is given one of four grades: mild, moderate, severe, or ve y severe. In cases of very severe severity requiring decortication, the possibility of VATS was excluded. Of the 50 cases, mild adhesions were detected in 15 cases(30.0%), moderate in 29 (58.0%), and severe in 6 (12.0%). As for the extent of the adhesions, 8 cases (16.0%) were categorized as degree 1, 32 cases (64. 0%) as degree II, and 10 cases (20.0%) as degree III. For patients with pleural adhesions, the operation time, the chest tube indwelling time, and the postoperative hospital stay were all longer than for patients in the non-adhesion group. Postoperative complications, namely prolonged air-leakage and pleural drain- age, were more common (18.0% and 6.0%, respectively) than in the non-adhesion group (5.1% and 1.7%, respectively). Only two bronchiectatic patients (4%) were converted to an open thoracotomy because of in- ability to control bleeding. Although complications were encountered more frequently in the group with adhesions, patients were still able to enjoy the benefi s of thoracoscopic surgery. It is advisable to proceed with thoracoscopic surgery even in cases of unpredicted pleural adhesions.
