ABSTRACT

BACKGROUND: In recent years, single-port video-assisted thoracoscopic surgery (VATS) for lobectomy in non-small cell lung cancer (NSCLC) patients has become increasingly common. The objective of this study was to compare the feasibility and safety of single-port and triple-port VATS lobectomy. METHODS: A total of 73 patients with NSCLC who underwent VATS lobectomy from December 2011 to August 2016 were retrospectively reviewed, including 47 in the triple-port group and 26 in the single-port group. Statistical analysis was performed after propensity score matching. Patients were matched on a 1-to-1 basis. RESULTS: Operative time and intraoperative blood loss in the triple-port group and the single-port group were similar (189.4±50.8 minutes vs. 205.4±50.6 minutes, p=0.259; 286.5±531.0 mL vs. 314.6±513.1 mL, p=0.813). There were no cases of morbidity or mortality. No significant differences in complications or the total number of dissected lymph nodes were found between the 2 groups. In the single-port group, more mediastinal lymph nodes were dissected than in the triple-port group (1.7±0.6 vs. 1.2±0.5, p=0.011). Both groups had 1 patient with bronchopleural fistula. Chest tube duration and postoperative hospital stay were shorter in the single-port group than in the triple-port group (8.7±5.1 days vs. 6.2±6.6 days, p=0.130; 11.7±6.1 days vs. 9.5±6.4 days, p=0.226). However, the differences were not statistically significant. In the single-port group, the rate of conversion to multi-port VATS lobectomy was 11.5% (3 of 26). The rates of conversion to open thoracotomy in the triple-port and single-port groups were 7.7% and 3.8%, respectively (p=1.000). CONCLUSION: In comparison with the triple-port group, single-port VATS lobectomy showed similar results in safety and efficacy, indicating that single-port VATS lobectomy is a feasible and safe option for lung cancer patients.

ABSTRACT

Broncho-pleural fistula (BPF) and esophago-pleural fistula (EPF) after pulmonary resection are challenging to manage. BPF is controlled by irrigation and sterilization, but such therapy is not sufficient to promote closure of EPF, which usually requires surgical management. However, it is generally difficult to select an appropriate surgical method for closure of BPF and EPF. Here, we report a case of concomitant BPF and EPF after left completion pneumonectomy, in which both fistulas were closed through a right thoracotomy.

ABSTRACT

BACKGROUND: The management of contralateral bullae incidentally found in radiological studies is controversial, largely due to the unpredictability of the natural course of incidentally found contralateral bullae. This study aimed to identify the factors associated with the contralateral occurrence of primary spontaneous pneumothorax (PSP), and to characterize the outcomes of contralateral bullae incidentally found in radiological studies. METHODS: From January 2005 to December 2008, 285 patients were admitted to our institution for PSP, and the patients underwent follow-up until August 2012. The relationships between the following variables and contralateral pneumothorax occurrence were evaluated: age, sex, smoking history, body mass index, ipsilateral recurrence, ipsilateral bullae size, the number of ipsilateral bullae, contralateral bullae size, and the number of contralateral bullae. RESULTS: The study group consisted of 233 males and 29 females. The mean age and mean body index of the patients were 23.85+/-9.50 years and 19.63+/-2.50 kg/m2. Contralateral PSP occurred in 26 patients. The five-year contralateral PSP occurrence- free survival rate was 64.3% in patients in whom contralateral bullae were found. CONCLUSION: The occurrence of contralateral PSP was associated with younger age, ipsilateral recurrence, and the presence of contralateral bullae. Contralateral PSP occurrence was more common in young patients and patients with recurrent PSP. Single-stage bilateral surgery should be considered if an operation is needed in young patients, patients with recurrent pneumothorax, and patients with contralateral bullae.

ABSTRACT

BACKGROUND: The development of diagnostic techniques and an awareness of health examinations can bring about an early diagnosis of lung cancer. However, appropriate postoperative management and adjuvant chemotherapy remain under debate in postoperative therapeutic strategy. The present study was conducted to assess the clinicopathologic factors that influence recurrence and prognosis after complete resection of lung cancer. METHODS: The present study analyzed 62 patients with lung cancer who underwent complete resection of diagnosed adenocarcinoma between 1994 and 2007. In addition to conventional factors, which include staging factor and histological evaluation, the present study also performed univariate and multivariate analyses to consider claudin, a cell adhesion molecule, as a prognostic factor by immunohistochemical staining. RESULTS: There was no correlation between conventional factors, including lymphatic and vascular invasion, and recurrence. However, there was a significant correlation between high expression of claudin 4 and cancer recurrence. In particular, there was a correlation between high expressions of claudin 1, 4, and 5 and a reduction of disease-free survival. CONCLUSION: Increased expressions of claudin 4 were negative prognostic factors in adenocarcinoma of the lung and thus could be used to identify high-risk patients for adjuvant chemotherapy, even if they had early-stage lung cancer. The present findings collectively suggest that consideration of claudin as a prognostic factor in the active postoperative treatment in patients at high risk will lead to better therapeutic outcomes with fewer side effects.

ABSTRACT

BACKGROUND: The aim of this study was to determine the survival rate of patients with non-small cell lung cancer (NSCLC) who were preoperatively diagnosed with a negative N2 lymph node, but postoperatively confirmed as a positive N2 node based on a pathological evaluation. MATERIALS AND METHODS: The hospital records of 248 patients from 1994 to 2009 with resected primary NSCLC who were preoperatively diagnosed with negative N2 lymph node, were retrospectively reviewed. Of these, after surgery, there were 148 (59.7%) patients with pathological N0, 54 (21.8%) with pathological N1 and 46 (18.5%) with pathological N2. RESULTS: The median follow-up period was 24 months (range, 1 to 132 months). The 5-year disease free survival rates were 60% in pN0, 44% in pN1, and 29% in pN2. The 5-year overall survival rates were 63.1% in pN0, 51.9% in pN1, and 33.5% in pN2. There were no statistically significant differences between pN1 and pN2 (p=0.326 and p=0.106, respectively). Thirty-three (71.7%) of the 46 pN2 patients had single-zone metastasis, and 13 patients (28.3%) had multiple-zone metastases over the two nodal zone metastasis. There were no statistical differences in the 5-year disease free survival rate and the 5-year overall survival rates between the two groups. CONCLUSION: The 5-year disease free survival and the overall survival rate of the patients with unsuspected N2 disease were statistically similar with that of the patients with pathological N1 disease. There was no statistically significant difference between the patients with a single-zone metastasis and a multiple zone metastasis.

ABSTRACT

BACKGROUND: Tuberculous abscess of the chest wall is a very rare disease. Few articles have reported on it and those that have enrolled few patients. To determine the characteristics of this disease and to suggest an optimal treatment strategy, we reviewed patients treated by surgical management. MATERIALS AND METHODS: Between October 1981 and December 2009, 68 patients treated by surgical management for a tuberculous abscess of the chest wall were reviewed retrospectively. RESULTS: Of 33 men and 35 women, 31 patients had a current or previous history of tuberculosis. The main complaints were chest pain, a palpable mass, pus discharge, and coughing. A preoperative bacteriologic diagnosis was performed in 12 patients. Abscess excision was performed in 54 cases, abscess cavity excision and partial rib resection in 13, and abscess excision and partial sternum and clavicle excision in 1 case. Postoperative wound infection was noted in 16 patients and a secondary operation was performed in 1 patient. Recurrence occurred in 5 patients (7.35%). Reoperation with abscess excision and partial rib resection was performed in all of the 5 cases. CONCLUSION: Complete excision of the abscess and primary closure of the wound with obliteration of space would decrease postoperative complications. Anti-tuberculosis medication may reduce the chance of recurrence.

ABSTRACT

Leiomyosarcoma of the mediastinum and primary leiomyosarcoma of the spine are exceedingly rare. In most cases, spinal leiomyosarcoma is metastatic. In this report, we describe the case of a 58-year-old man who presented with a large leiomyosarcoma of the posterior mediastinum that extended into the adjacent spinal canal. The tumor was completely resected from the mediastinum, but only subtotally removed from the spinal canal because the spinal mass had tightly invaded the spinal cord. Because the patient's postoperative condition was poor, no adjuvant radiotherapy or chemotherapy was administered. He expired 3 months after the surgery due to relapse; the spinal and mediastinal tumor remained at the preoperative size.

ABSTRACT

BACKGROUND: The aim of this study is to investigate the clinical characteristics and management of intrathoracic bronchogenic cysts. MATERIALS AND METHODS: Twenty-four (n=24) patients with intrathoracic bronchogenic cysts were treated surgically between August 1990 and December 2009 at our institution. Patients were divided into two groups by bronchogenic cyst location: mediastinal or intrapulmonary. Symptoms at diagnosis, radiologic findings, locations, surgical methods, pathological findings, and surgical outcomes were investigated retrospectively from consecutive patient medical records. RESULTS: There were 12 females (50.0%). The mean age was 26.8 (range, 5 to 64) years. The mean follow-up period was 27.3 (range, 1 to 121) months. There were 15 (62.5%) mediastinal and 9 (37.5%) intrapulmonary bronchogenic cysts. Symptoms occurred in 8 patients with mediastinal bronchogenic cysts (53.3%) and 5 patients with intrapulmonary bronchogenic cysts (55.6%) (p=1.000). On computed tomography (CT), 7 patients (46.7%) showed homogenous solid masses in mediastinal bronchogenic cysts and five (55.6%) patients exhibited heterogeneous cystic masses with air-fluid levels in intrapulmonary bronchogenic cystic masses. Open thoracotomy was performed in 17 (70.8%) patients, and video-assisted thoracic surgery was performed in 7 (29.2%) patients. On pathological findings, there were 16 (66.7%) complicated cysts, and in 13 symptomatic patients, 11 (84.6%) patients had complicated cysts. There was no operative death in this study. During the follow-up period, no recurrence was detected. CONCLUSION: Intrathoracic bronchogenic cysts have a wide variety of clinical characteristics and radiologic findings. Even though some patients do not experience symptoms and signs caused by bronchogenic cysts, serious symptoms and complications may develop with the passage of time.

ABSTRACT

An azygos vein aneurysm is a very rare cause of a posterior mediastinal mass. Once the diagnosis has been confirmed, no treatment is usually required. However, the aneurysm can thrombose, and this may lead pulmonary thromboembolism, or the aneurysm may rupture. In these instances, the excision of the mass is recommended. Video-assisted thoracic surgery techniques have considerably improved. If it is necessary to remove the aneurysm, video-assisted thoracic surgery may be a good option for surgical treatment. We report a case of an aneurysm of the azygos arch that was successfully resected by video-assisted thoracic surgery.

ABSTRACT

Lymphoepithelioma-like carcinoma (LELC) of the lung is a very rare tumor. Originally described in the nasopharynx as lymphoepithelioma, this carcinoma has also been found in the stomach, esophagus, thymus, cervix, urinary bladder, skin, and salivary glands. Histologically, it is an undifferentiated carcinoma that has a syncytial appearance with tumor cells and is infiltrated by numerous lymphocytes, macrophages, and plasma cells. LELC of the lung occurs more commonly in Asians, particularly Chinese. Many studies have reported the association between Epstein-Barr virus (EBV) and LELC of the lung in Asian patients. A 45-year-old man had a solitary pulmonary nodule on a routine chest X-ray examination. As a malignant tumor was suspected, surgical resection was performed to establish the correct diagnosis. The pathology of the excised tumor demonstrated LELC of the lung. This is the first report of LELC of the lung in Korea.

ABSTRACT

Bronchogenic cysts are developmental foregut anomalies usually located within the mediastinum or lung parenchyma. An isolated bronchogenic cyst of the diaphragm is very rare. Our case was a 56-year-old female patient who presented with pleuritic chest pain in her right chest. Chest and abdominal computed tomography revealed a large lobulated cystic mass that was accompanied with pleural effusion in the right lower hemithorax. The tumor showed focally calcified areas in the wall and abutted against the diaphragm. We performed complete excision of the cyst including a portion of the diaphragm attached to it. The pathological diagnosis was established as the bronchogenic cyst originating from the diaphragm. We report this case with a review of the literature.

ABSTRACT

BACKGROUND: Video-assisted thoracic sympathicotomy plays an important for the treatment of essential hyperhidrosis. Patients are usually satisfied with the surgical outcome at the early post-operative period, but suffer recurrence and compensatory sweating in the late post-operative period. There are many sympathicotomy methods to minimize recurrence and compensatory sweating. We compared the outcome of sympathicotomy methods above the third rib (R3) and the fourth rib (R4) with regards to symptoms, satisfaction, recurrence, and compensatory palmar and axillary hyperhydrosis. MATERIALS AND METHODS: From January 1999 to April 2009, 39 cases of thoracoscopic sympathicotomy at the third rib (R3), and 94 cases of thoracoscopic sympathicotomy at the fourth rib (R4) for palmar and axillary hyperhidrosis were compared for early and late post-operative satisfaction, compensatory sweating and recurrence. RESULTS: There was no sex or age difference between groups. Early satisfaction was 94.9% and 98.9% in the R3 group and R4 group, respectively. There was no difference in early satisfaction (94.9% in R3 and 98.9% in R4), late satisfaction (84.6% in R3 and 89.4% in R4), or recurrence (17.9% in R3 and 17.0% in R4) between groups. There was significant difference in compensatory sweating (71.8% in R3 and 33% in R4, p=0.002). CONCLUSION: R4 sympathicotomy demonstrated superior efficacy in the treatment of compensatory sweating compared to R3 in palmar and/or axillary hyperhidrosis.

ABSTRACT

BACKGROUND:Thoracoscpic sympathicotomy is an effective treatment for essential hyperhidrosis. Patients are generally satisfied with the surgery at the early post operative period, but they suffer from recurrence and compensatory sweating at the late post operative period. There are many sympathicotomy methods for minimizing recurrence and the compensatory sweating. We compared the outcome from between the R3 and R4 sympathicotomy methods for the symptoms, satisfaction, recurrence and compensatory sweating. MATERIAL AND METHOD: From January 1999 to July 2007, 39 cases of thoracoscopic sympathicotomy at the 3rd rib (R3) and 72 cases of thoracoscopic sympathicotomy at the 4th rib (R4) for treating palmar hyperhidrosis were compared for the early and late satisfaction, the compensatory sweating and recurrence. RESULT: There is no difference of gender and age for the 2 groups. Early satisfaction was reported by 94.9% of the R3 patients and by 98.7% of the R4 patients. 84.6% of the R3 patients reported late satisfaction and 87.5% of the R4 patients reported late satisfaction. There were no significant differences between the groups for the early and late satisfaction. But there was a difference between the groups for compensatory sweating (23.1% in the R3 group and 9.7% in the R4 group (p=0.020)). The reoperation rate due to recurrence was 5.1% in the R3 group and 4.2% in the R4 group. There was no significant difference between the groups for recurrence. CONCLUSION: R4 sympathicotomy has excellent therapeutic results for compensatory sweating as compared to R3 sympathicotomy for treating palmar hyperhidrosis.

ABSTRACT

PURPOSE : To determine the etiology of distant metastasis that was a major factor in the death of a patient with early stage non-small cell lung cancer (NSCLC). Recent studies have suggested that UFT may be effective adjuvant chemotherapy for completely resected early stage NSCLC. This study was designed to clarify the feasibility of UFT adjuvant chemotherapy in early stage NSCLC. MATERIALS AND METHODS : We administered UFT adjuvant chemotherapy for 24 months to patients with completely resected stage I NSCLC from January 2003 to January 2007 and compared the results in patients who did not receive UFT. The control group was recruited between March 1992 and December 2003. The UFT group was followed until death or the study cut-off date (20 October 2007). The control group was followed until September 2004. RESULTS : The UFT group was comprised of 28 patients. In the UFT group, 18 patients had adenocarcinomas and 10 patients had squamous cell carcinomas. The control group was comprised of 91 patients. In the control group, 34 patients had adenocarcinomas and 57 patients had squamous cell carcinomas. Thirty-five patients in the control group recurred (38.5%) and 9 patients in the UFT group (32%) recurred. CONCLUSION : The oral administration of UFT adjuvant chemotherapy was well-tolerated long-term without severe complications. Especially in stage I NSCLC, there was an improvement in the survival rate in patients treated with UFT, even though there was no statistical difference compared to the control group. Additional studies will be necessary to demonstrate the clinical significance of UFT treatment in early NSCLC

ABSTRACT

BACKGROUND: Primary malignant lymphoma of the lung is a very rare neoplasm. Although the prognosis of lymphoma is favorable, the clinical features, prognostic factors and management have not been clearly defined. MATERIAL AND METHOD: We retrospectively reviewed the records of 8 patients we managed between 1994 and 2006. They all had malignant lymphoma on the pathologic examination of the lung with no evidence of mediastinal adenopathy and extrathoracic disease, and no past history of lymphoma. RESULT: The study group consisted of 3 males and 5 female patients with a mean age of 53.9 years. Three patients were asymtomatic and 5 patients were seen with pulmonary or systemic symptoms. The diagnostic methods were 3 CT needle aspiration biopsies, 1 bronchoscopic biopsy and 4 surgical methods (wedge resection, lobectomy). There were 3 patients with MALT lymphoma, two with diffuse large B-cell lymphoma, two with small lymphocytic lymphom, and one with follicular lymphoma. The 8 patients were treated with a variety of modalities, including surgery, chemotherapy, radiotherapy and combination therapy. The 8 patients have survived for a median follow-up of 38 months. CONCLUSION: Although this entity of lymphoma appears to have a good prognosis, further clinical experience and long-term follow-up are needed to identify its clinical features, prognostic factors and management.

ABSTRACT

BACKGROUND: Perforation of the esophagus is a deadly injury that requires expert management for survival. The mediastinal contamination with microorganisms, gastric acid, and digestive enzymes results in a mediastinitis that is often fatal if untreated. MATERIAL AND METHOD: Between January 1990 and June 2004, 38 patients with esophageal perforation were treated in our hospital. Retrospective review of these cases has been performed. RESULT: There were 28 males and 10 females. The mean age was 43.84+/-18.89 years (range 1~73 years). Spontaneous rupture was found in 34% of perforations, iatrogenic perforation in 32% and traumatic perforation in 34%. Perforation occurred in the cervical esophagus in 8 cases, thoracic esophagus in 29 and abdominal esophagus in 1. In the cervical esophageal perforation, managements were primary closure in 8 and drainage in 2. In the thoracic esophageal perforation, managements were primary closure in 14, resection in 3 and conservative management in 12. The mortality rate was 25% in cervical esophageal perforation and 34.5% in thoracic esophageal perforation. We revealed risk factor of esophageal perforation to be peropertaive septic condition (p=0.005). CONCLUSION: Most important risk factor of esophageal perforation was preoperative septic condition. Preoperative prompt and aggressive preoperative treatment may improve the survival rate of esophageal perforation.

ABSTRACT

PURPOSE: Overexpression of COX-2, an enzyme responsible fro the synthesis of prostaglandins, is well linked to human chronic lung diseases. The mechanism by which COX-2 expression is increased or enhanced in cancer cells remains largely unknown. Any compound which can reduce COX-2 expression may be considered as an anti-cancer agent. MATERIALS AND METHODS: Leptomycin B (LMB) is a metabolite of Streptomyces and a specific inhibitor of CRM1 nuclear export receptor. A549 is a human lung cancer cell line. To evaluate the effect of LMB on COX-2 expression induced by IL-1beta, a pro-inflammatory cytokine, in A549 cells, Western blot and RT-PCR assays were applied to measure COX-2 protein and mRNA expressions in response to IL-1beta, respectively. Luciferase experiments were done to measure promoter activity of COX-2, NF-kappaB or AP-1. CRM1 siRNA trasfection experiment was performed to knock-down endogenous CRM1. Biochemical protein fractionation method was also carried out to see intracellular localization of proteins. RESULTS: LMB at 9 nM strongly suppressed IL-1beta-induced expression of COX-2 protein that was attributable to decreased COX-2 transcript and promoter activity, but not mRNA stability. Distinctly, knock-down of CRM1 had no effect on COX-2 expression by IL-1beta. Moreover, LMB did not affect IL-1beta-induced phosphorylation of ERK-1/2, JNK- 1/2, and p38 MAPK or AP-1 promoter activity. In contrast, LMB blocked IL-1beta- mediated cytosolic IkappaB-alpha degradation, p65 NF-kappaB nuclear translocation, and NF-kappaB promoter activity. CONCLUSION: LMB potently down-regulates IL-1beta- induced COX-2 at transcriptional level in A549 cells, in part, through modulation of the IkappaB-alpha/NF-kappaB pathway but independent of CRM1, MAPKs and AP-1.

ABSTRACT

Antireflux surgery has been indicated in gastroesophageal reflux disease (GERD) that does not respond to medical treatments. Although the most commonly performed operation is Nissen fundoplication, Belsey Mark IV fundoplication is indicated for more complicated cases, such as, in cases of a failed Nissen operation or a long lasting hiatal hernia. Here, we report a case of Belsey Mark IV fundoplication for a failed Nissen fundoplication. The infant developed frequent times of aspiration pneumonia after initial Nissen for a hiatal hernia with GERD during the newborn period. At 15 months of age, a 2nd Nissen operation was attempted, but fundoplication was not available because of excessive mesenteric adherence to the liver and cardia. Therefore, Belsey Mark IV fundoplication was performed via trans-thoracic approach, which can provide full esophageal mobilization and better visualization of the herniated fundus and the surrounding tissues. Subsequently, she has shown an improved general condition without GERD.
