Persistent left superior vena cava (PLSVC) is the most common anomalous thoracic venous drainage. A PLSVC usually drains into the right atrium through a dilated coronary sinus. It is rare that a ...PLSVC flows directly into the left atrium, and even rarer that it connects to the left upper pulmonary vein (LUPV). We report a case, wherein the LUPV connected to both the PLSVC and the left atrium.
Completion lobectomy long after segmentectomy in the same lobe is extremely difficult because of severe adhesions around hilar structures, especially in cases involving video-assisted thoracoscopic ...surgery (VATS) completion lobectomy. We report and compare the surgical outcomes of patients who underwent VATS or thoracotomy completion lobectomy long after radical segmentectomy for lung cancer.
We retrospectively evaluated the surgical outcomes of completion lobectomies performed at our institute long after radical segmentectomies for lung cancer in the same lobe. The efficacy and safety of VATS completion lobectomy was compared to that of thoracotomy completion lobectomy.
Ten of 228 patients who underwent radical segmentectomy for lung cancer between 2009 and 2018 underwent completion lobectomy at least a month after segmentectomy; five patients underwent VATS completion lobectomy. None of the patients underwent VATS left upper completion lobectomy, and conversion to thoracotomy was required in one patient. There were no significant differences between VATS and thoracotomy completion lobectomies in the median operative times (VATS 295 min, thoracotomy 339 min, p = 0.55), intraoperative blood loss volumes (VATS 350 mL, thoracotomy 500 mL, p = 0.84), intervals between initial segmentectomy and completion lobectomy (VATS 40 months, thoracotomy 48 months, p = 0.55), and number of patients with pulmonary artery injury (VATS 1, thoracotomy 2, p = 0.49). There was no operation-related mortality.
VATS completion lobectomy long after segmentectomy for lung cancer could be performed without fatal complications unless severe adhesions are observed around each main pulmonary artery.
Purpose
Mediastinal node dissection (MND) is an integral component of the surgical treatment for non-small cell lung cancer (NSCLC). Although video-assisted thoracoscopic surgery (VATS) has been used ...increasingly for lung cancer treatment, the accuracy of by VATS MND still remains controversial. We reviewed the surgical results of VATS MND for NSCLC.
Methods
A systematic review of literature was performed, and articles that fully described the surgical procedure, devices, and results of VATS MND were selected to compare the efficacy of MND by VATS and thoracotomy.
Results
Various techniques and equipments have been shown to perform adequate MND, but there is an argument as to the method of estimation of the accuracy of MND. Most of the recent studies showed that the nodal upstaging and number of dissected nodes are significantly lower by VATS than after thoracotomy. Oppositely, some studies showed VATS noninferiority in these issues. Complications such as chylothorax, pleural effusion, bleeding, and nerve damage were similar in both groups.
Conclusions
Although ND by VATS remains controversial, VATS MND is becoming easier and more feasible owing to the development of more advanced endoscopic cameras and equipments. We should learn further to become more adept at performing adequate ND by VATS.
Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic, progressive fibrosing interstitial pneumonia of unknown cause. IPF is associated with an increased risk of lung cancer, ...and lung cancer patients with IPF undergoing pulmonary resection for non-small cell lung cancer have increased postoperative morbidity and mortality. Especially, postoperative acute exacerbation of IPF (AEIPF) causes fatal status and long-term outcomes are worse than for patients without IPF, although certain subgroups have a good long-term outcome. A comprehensive review of the current literature pertaining to AEIPF and the late phase outcome after the context of a surgical intervention was performed.
Combined resection of a phrenic nerve is occasionally required in T3 primary lung carcinomas invading the phrenic nerve to completely remove a malignant tumour, resulting in diaphragmatic paralysis. ...We describe the first case of thoracoscopic lobectomy and diaphragmatic plication as a one-stage surgery for lung cancer invading the phrenic nerve.
A 56-year-old woman with a T3N0M0 primary adenosquamous carcinoma in the left upper lobe presented with suspicious invasion to the anterior mediastinal fat tissue and left phrenic nerve and underwent left upper lobectomy, node dissection, and partial resection of the anterior mediastinal fat tissue with the left phrenic nerve. Furthermore, thoracoscopic diaphragmatic plication was performed as a concomitant procedure. The patient's postoperative course was favourable, without any complications, and respiratory function was preserved for 1 year postoperatively.
Thoracoscopic one-stage lobectomy and diaphragmatic plication for T3 lung cancer invading the phrenic nerve is effective for preservation of postoperative pulmonary function.
Objective: It remains controversial whether video-assisted thoracoscopic surgery (VATS) major pulmonary resection (VMPR) with systematic node dissection (SND) is a feasible approach for clinical N0 ...and pathological N2 non-small cell lung cancer (cN0-pN2 NSCLC). We compared the clinical outcome of patients who underwent VMPR with SND for cN0-pN2 NSCLC with the outcome of patients who underwent MPR with SND by thoracotomy. We conducted this study to determine the feasibility of VMPR for cN0 and pN2 NSCLC patients and intraoperative node staging by node sampling. Methods: Between 1997 and 2006, 770 patients underwent MPR with SND for NSCLC, wherein 450 patients had VMPR and 320 were subjected to open thoracotomy. There were 673 clinical N0 patients. Among them, we retrospectively reviewed 69 patients (10.3%) with cN0-pN2 NSCLC of which the greatest tumor dimension ranged from 20 to 50 mm. These patients were divided into two groups: 37 patients under group V, who underwent VMPR, and 32 patients under group T, who underwent MPR by thoracotomy, for cN0-pN2 NSCLC. The majority of the patients underwent postoperative chemotherapy. Results: There were no differences between the two groups regarding preoperative data or the number of nodes dissected. The rate of nodal metastasis (number of metastatic nodes/number of dissected nodes) was similar between the two groups (group V vs group T, 0.24 vs 0.24 in total nodes dissected, 0.24 vs 0.23 in mediastinal nodes dissected). The 3-year and 5-year recurrence-free survivals were similar (60.9% vs 49.6% and 60.9% vs 49.6%), as well. Most of the pattern of recurrence was due to remote metastasis. In like manner, the 3-year and 5-year survivals were similar (67.6% vs 57.7% and 45.4% vs 41.1%). Conclusions: This study demonstrates that VMPR with SND is a feasible surgical therapy for cN0-pN2 NSCLC without loss of curability. It is unnecessary to convert the VATS approach to thoracotomy in order to do SND even if pN2 disease is revealed during VMPR.

Spontaneous thymic hemorrhage in a normal thymus in neonates and infants has been reported in the literature. Only one case of spontaneous thymic hemorrhage in an adult has been reported to our ...knowledge. We herein report the case of an adult who had a cardiac operation 26 years previously and who was on anticoagulation. He experienced acute hemorrhage in a normal thymus, and this was not thought to be attributable to an accidental cause such as trauma or to hypertension.
Abstract
OBJECTIVES
Spontaneous pneumothorax (SP) results from the rupture of blebs or bullae. It has been suggested that changes in weather conditions may trigger the onset of SP. Our aim was to ...examine the association between the onset of primary SP with weather changes in the general population in Sapporo, Japan.
METHODS
From January 2008 through September 2013, 345 consecutive cases with a diagnosis of primary SP were reviewed. All cases of primary SP developed in the area within 40 km from the Sapporo District Meteorological Observatory. Climatic measurements were obtained from the Observatory, which included 1-h readings of weather conditions. Logistic regression model was used to obtain predicted risks for the onset of SP with respect to weather conditions.
RESULTS
SP occurred significantly when the atmospheric pressure decreased by − 18 hPa or less during 96 h before the survey date (odds ratio = 1.379, P = 0.026), when the pressure increased by 15 hPa or more during 72 h before the survey date (odds ratio = 1.095, P = 0.007) and when maximum fluctuation in atmospheric pressure over 22 hPa was observed during 96 h before the survey date (odds ratio = 1.519, P = 0.001). Other weather conditions, including the presence of thunderstorms, were not significantly correlated with the onset of pneumothorax.
CONCLUSIONS
Changes in atmospheric pressure influence the onset of SP. Future studies on the relationship between the onset of SP and weather conditions on days other than before the onset and with large number of patients may enable us to predict the onset of SP in various regions and weather conditions.
