Abstract
BACKGROUND No proven treatment after the development of primary graft dysfunction (PGD) is currently available. Here, we established a novel strategy of in vivo lung perfusion (IVLP) for the treatment of PGD. IVLP involves the application of an in vivo isolated perfusion circuit to an implanted lung. This study aimed to explore the effectiveness of IVLP vs conventional post-lung transplant (LTx) extracorporeal membrane oxygenation (ECMO) treatment using an experimental swine LTx PGD model. METHODS After 1.5-hour warm ischemia of the donor lungs, a left LTx was performed. Following the confirmation of PGD development, pigs were divided into 3 groups (n = 5 each): control (no intervention), ECMO, and IVLP. After 2 hours of treatment, a 4-hour functional assessment was conducted, and samples were obtained. RESULTS Significantly better oxygenation was achieved in the IVLP group (p ≤ 0.001). Recovery was confirmed immediately and maintained during the following 4-hour observation. The IVLP group also demonstrated better lung compliance than the control group (p = 0.045). A histologic evaluation showed that the lung injury score and terminal deoxynucleotidyl transferase dUTP nick end labeling assay showed significantly fewer injuries and a better result in the wet-to-dry weight ratio in the IVLP group. CONCLUSIONS A 2-hour IVLP is technically feasible and allows for prompt recovery from PGD after LTx. The posttransplant short-duration IVLP strategy can complement or overcome the limitations of the current practice for donor assessment and PGD management.

Abstract
An 80-year-old woman with a history of left breast cancer complained of dysphagia. At the age of 67 years, she had undergone a left modified radical mastectomy, chemotherapy, and endocrine therapy for left breast cancer. Six years after adjuvant therapy completion, she developed dysphagia. Chest CT showed only midesophageal stenosis. Endoscopic examination revealed whole circumferential stenosis without mucosal abnormality located 25 cm from the incisors, and a biopsy showed histologically normal mucosa. Endoscopic balloon dilatation was performed 5 times in 1 year and 3 months. Subsequently, a biopsy specimen revealed adenocarcinoma, which suggested metastasis from the previous breast cancer. One month after the initiation of tamoxifen administration, dyspnea due to pleural effusion was encountered. We treated this via pleural adhesion therapy and changed the treatment to paclitaxel plus bevacizumab combination therapy. She continued paclitaxel plus bevacizumab therapy for 1 year and 4 months without any signs of recurrence.

Abstract
Esophagectomy and pancreatectomy are recognized as highly invasive procedures with relatively high complication rates; therefore, careful indication decisions are required. The depth of tumors invading adjacent organs, such as the aorta, vertebral body, and trachea, is defined as T4, and are estimated to have a low survival rate even after treatment. Conversely, pancreatic invasion of esophageal cancer is uncommon and not clearly defined as T4. Thus, it is often difficult to decide on a treatment strategy for locally advanced esophageal cancer. In this study, we describe three cases of esophagectomy with combined resection of the pancreas and spleen for esophageal cancer or esophagogastric junction cancer with invasion of the pancreatic body or tail. To the best of our knowledge, this is the first report of esophagectomy and combined resection of the pancreas and spleen in multiple patients from a single institution.

Abstract
BACKGROUND The esophagus has no serosa; therefore, esophageal cancer may quickly invade its adjacent organs. In recent years, reports of conversion surgery (CS) and salvage surgery (SS) have described resection of esophageal cancer previously considered unresectable, with the addition of intensive preoperative chemotherapy or chemoradiotherapy. Currently, there is no established method for determining whether tumor excision is possible. Additionally, differences in surgical approaches between facilities may influence outcome after resection. However, the option for resection is considered a significant factor in determining a patient's prognosis. METHODS Patients who were diagnosed with advanced-stage (T3 or higher) squamous cell carcinoma of the esophagus and subsequently underwent resection with CS or SS were included in the study. Resection was performed through a small thoracotomy using a thoracoscope. Clinicopathologic factors, such as complete resection rate (R0) and prognosis, were investigated. RESULTS A total of 49 surgeries were conducted: 39 CS and 10 SS cases. The male-to-female ratio was 37:12. R0:R1:R2 equals 42:3:4, and the R0 resection rate was 85.7%. The 5-year survival rates for CS and SS cases were 69.2% and 32.1%, respectively. The 5-year survival rates for R0, R1, and R2 resections were 63.4%, 0.0%, and 25.0%, and those for R0 and R1 + 2 resections were 63.4% and 14.3%, respectively, indicating that the prognosis for R0 resection cases was significantly better (P = 0.001 and P = 0.001, respectively). Regarding chemotherapy for CS, 29 patients received 5-FU and cisplatin therapy, whereas 10 patients received 5-FU, cisplatin, and docetaxel (DCF) therapy. After 2015, the ratio of DCF was significantly high, and the R0 resection rate was 100% in patients who received DCF therapy. CONCLUSIONS In this study, a satisfactory R0 rate was achieved using the magnifying effect of the thoracoscope while ensuring safety during thoracotomy. TRIAL REGISTRATION This was a single-center cohort study wherein clinical data were retrospectively registered. This study was approved by the Chiba Cancer Center review board (H29-262). All procedures adhered to the ethical standards of the responsible committee on human experimentation and the Helsinki Declaration of 1964 and its later amendments.

Abstract
BACKGROUND Anomalous bifurcation of the right superior pulmonary vein is an important anomaly that should be recognized not only in respiratory and cardiac surgeries, but also in esophageal surgery for the safe performance of surgery. We report a case in which thoracoscopic esophagectomy was safely performed using preoperative three-dimensional computed tomography (3D CT) imaging. CASE PRESENTATION An 81-year-old male patient received an upper gastrointestinal endoscopy, which revealed a 20-cm incisor at the entrance, 43-cm EGJ, and 30-mm large type 1 + IIc lesion between the 23-cm and 26-cm incisors; biopsy showed squamous cell carcinoma (SCC). Contrast-enhanced CT showed wall thickening in the anterior wall of the upper thoracic esophagus, without evidence of multi-organ invasion or lymph node metastasis. In addition, a break in the right pulmonary vein passing dorsal to the right main bronchus and flowing directly into the left atrium was observed, and 3D CT was performed preoperatively to confirm the 3D positioning. Positron emission tomography (PET)-CT showed a high degree of accumulation (SUVmax 19.95) in the upper thoracic esophagus. The patient was diagnosed with upper thoracic esophageal cancer, cT2N0M0 cStage II, and underwent thoracoscopic subtotal esophagectomy (three-region dissection) and gastric tube reconstruction. The dorsal inflow of the pulmonary vein in the right main bronchus, which was recognized on preoperative CT, was confirmed and preserved. The pathological diagnosis was basaloid squamous cell carcinoma, pT1b(SM1)N0(0/58)M0 pStage I. The postoperative course was uneventful, and the patient was discharged on postoperative day 20. CONCLUSIONS The anomalous bifurcation of the pulmonary vein in the right upper lobe area required attention because of its potential to cause massive bleeding and difficulty in securing the operative field if misidentified and damaged during surgery. Although it is not frequently encountered, it is the bifurcation anomaly that esophageal surgeons must bear in mind due to its severe consequences. Preoperative image-reading and intraoperative manipulation of this vessel are imperative for surgical safety.

Abstract
BACKGROUND/AIM We evaluated the efficacy of "the tumor immune microenvironment (TIME) classification" for predicting clinical response to immune checkpoint inhibitors (ICIs) in patients with non-small cell lung cancer (NSCLC). In addition, we aimed to evaluate the "modified TIME classification", which adds the vascular endothelial growth factor (VEGF) status to TIME. MATERIALS AND METHODS Programmed cell death receptor ligand-1 (PD-L1), CD8 T cell tumor-infiltrating lymphocytes (CD8+TILs) count and VEGF expression analyses were performed using immuno - histochemistry in 44 patients who had undergone ICI monotherapy. RESULTS Regarding TIME classification, type-I (PD-L1 high and CD8+TILs high) had a significantly higher response than the other types. Using the modified TIME classification, type-IA (PD-L1 high, CD8+TILs high, and VEGF low) had a significantly higher response than the other types. CONCLUSION The modified TIME classification, which adds tumor VEGF expression to "the TIME classification", could be useful in predicting clinical response to ICI monotherapy.

Abstract
BACKGROUND Although there are many studies on primary esophageal adenocarcinoma arising from Barrett's esophagus or ectopic gastric mucosa, reports on adenocarcinoma arising from esophageal cardiac glands are extremely rare. Herein, we report a case of mid-thoracic cancer antigen 19-9 (CA 19-9)-producing primary esophageal adenocarcinoma, which presumably originated from the cardiac glands. CASE PRESENTATION A 74-year-old man was referred to our department with advanced esophageal cancer, which initially presented with dyspepsia. Serum levels of cancer antigen 19-9 (CA 19-9) were elevated (724.89 U/ml). Upper gastrointestinal endoscopy revealed a type 2 tumor on the posterior wall of the mid-thoracic esophagus approximately 29-32 cm from the incisor. Mucosal biopsy was consistent with a diagnosis of adenocarcinoma. Contrast-enhanced computed tomography showed a circumferential wall thickening in the mid-thoracic esophagus without enlarged lymph nodes or distant metastasis. Positron emission tomography-computed tomography showed accumulation in the primary tumor, but no evidence of lymph node or distant metastasis. According to these findings, the adenocarcinoma was staged as cT3N0M0, thereby, requiring subtotal esophagectomy with lymph node dissection. Postoperative course was uneventful. Histopathologic analysis revealed a 50 × 40 mm moderately differentiated adenocarcinoma with invasion to the thoracic duct and lymph node metastasis at #108(1/4), #109R(1/3), and #109L(1/3). After surgery, the stage was revised to moderately differentiated pT4apN2pM0 (pStage III). Immunostaining revealed expression of CA19-9 and suggested esophageal cardiac gland origin of the tumor. Three months after the surgery, the patient showed no recurrence and is undergoing outpatient observation. CONCLUSIONS We experienced a case of mid-thoracic CA19-9-producing primary esophageal adenocarcinoma, which was presumed to have originated in the esophageal cardiac glands. Due to the scarcity of studies regarding this condition, specific management needs to be further clarified.

Abstract
We present 2 cases of "hybrid lung transplant," which included sequentially implanting a living lobar graft to 1 side and a cadaveric graft to the other side. This procedure was approved by the institutional review board at Okayama University Hospital. The 2 recipients were diagnosed with severe idiopathic pulmonary fibrosis, and living donor lobar lung transplant was considered; however, 2 appropriate donors were not available. Therefore, we accepted extended criteria donor lungs with a partial pressure of oxygen/fraction of inspired oxygen ratio of <251 mm Hg. However, 1 of the 2 patients developed grade 2 primary graft dysfunction. The living donor lobar lung had a low volume but was in good condition, which contributed to the patient's recovery after primary graft dysfunction during the perioperative period. The other patient's status of bronchiolitis obliterans syndrome had gradually progressed to grade 3, and only the living donor lung was functioning at that time. However, both patients are alive 5.5 and 4.2 years after lung transplant, respectively. Hybrid lung transplantation may increase patients' chances of receiving transplants because patients are not likely to survive while waiting for ideal donor lungs to become available.

Abstract
PURPOSE Anti-human leukocyte antigen (HLA) immunoglobulin (Ig) M production stimulated by an alloantigen is sensitive, making IgM a novel potential marker of allorejection after organ transplantation. This study examined the relationship between the serum levels of anti-HLA IgM early after clinical lung transplantation (LTx) and the post-transplant outcomes. METHODS Thirty-one consecutive patients who underwent deceased LTx were included. Immunoreactivity against HLA was retrospectively analyzed by measuring the anti-HLA IgM levels in the serum sampled for the first 14 days after LTx. The flow panel reactive antibody technique was used. The ratio of the anti-class I IgM level at each day to baseline was obtained, and the peak IgM level was determined for each case. The correlation between the peak IgM level and subsequent development of acute rejection (AR), chronic lung allograft dysfunction (CLAD), and survival outcomes were examined. RESULTS The peak IgM level was a significant risk factor for AR within 90 days in univariate and multivariate analyses. In the long term, the patients with positive IgM (peak level > 1.8) tended to have a poorer CLAD-free and overall survival than those with negative IgM. CONCLUSION Elevation of anti-HLA IgM levels early after LTx may be correlated with a higher incidence of rejection and negative clinical outcomes.

Abstract
PURPOSE The scheduled administration of intravenous acetaminophen (scheduled-IV-AcA) is one of the more effective multimodal analgesic approaches for postoperative pain in abdominal/orthopedic surgeries. However, there is little evidence concerning scheduled-IV-AcA after general thoracic surgery, especially when limited to video-assisted thoracoscopic surgery (VATS). We investigated the efficacy of scheduled-IV-AcA administration in patients after undergoing VATS. METHODS Ninety-nine patients who underwent VATS lobectomy or segmentectomy via an 8-cm access window and 1 camera port were retrospectively reviewed by categorizing them into groups either with scheduled-IV-AcA (Group AcA: n = 29) or without it (Group non-AcA: n = 70). Group AcA received 1 g of IV-AcA every 6 h from the end of the operation until the end of POD2. Postoperative pain was measured using a numeric rating scale (NRS) three times per day until discharge. RESULTS NRS scores were significantly lower in Group AcA with motion (on POD1 to the first point of POD2) than in Group non-AcA. Group non-AcA was also more likely to use additional analgesics than Group AcA (39% vs. 17%, p = 0.058). CONCLUSIONS Scheduled-IV-AcA administration is a safe and effective multimodal analgesic approach in patients undergoing VATS pulmonary resection via an 8-cm access window.

Abstract
PURPOSE Sarcomas are among the most refractory malignant tumors and often recur as pulmonary metastasis. Although the presence of a high neutrophil-to-lymphocyte ratio (NLR) has been associated with the prognosis of several malignancies, the relationship between the NLR and sarcoma with pulmonary metastasis is unclear. We investigated the impact of the NLR in patients who underwent surgical resection for metastatic lung tumors from various sarcomas. METHODS The subjects of this retrospective study were 158 patients with metastatic lung tumors from various sarcomas, who underwent initial pulmonary metastasectomy between 2006 and 2015. We examined the clinicopathological variables, including the NLR and the characteristics of surgical procedures. Survival was estimated by the Kaplan-Meier method and prognostic factors were evaluated by multivariate analysis. RESULTS Multivariate analysis revealed significantly better survival of the group with an NLR < 2.26 immediately before the most recent pulmonary metastasectomy, in addition to such factors as the largest resected lesion being < 22 mm, a disease-free interval of > 2 years, and 3 or more pulmonary metastasectomies. CONCLUSION The NLR immediately before the most recent pulmonary metastasectomy is a novel independent prognostic factor, which may be helpful when considering repeated pulmonary metastasectomy.

Abstract
BACKGROUND Lung transplantation (LTx) is still limited by the shortage of suitable donor lungs. Developing flexible surgical procedures can help to increase the chances of LTx by unfolding recipient-to-donor matching options based on the pre-existing organ allocation concept. We report a case in which a successful left-to-right inverted LTx was completed using the interposition of a pericardial conduit for pulmonary venous anastomosis. CASE PRESENTATION A left lung graft was offered to a 59-year-old male who had idiopathic pulmonary fibrosis with predominant damage in the right lung. He had been prescribed bed rest with constant oxygen inhalation through an oxymizer pendant and had been on the waiting list for 20 months. Considering the condition of the patient (LAS 34.3) and the scarcity of domestic organ offers, the patient was highly likely to be incapable of tolerating any additional waiting time for another donor organ if he was unable to accept the presently reported offer of a left lung. Eventually, we decided to transplant the left donor lung into the right thorax of the recipient. Because of the anterior-posterior position gap of the hilar structures, the cuff lengths of the pulmonary veins had to be adjusted. The patient did not develop any anastomotic complications after the transplantation. CONCLUSIONS A left-to-right inverted LTx is technically feasible using an autologous pericardial conduit for pulmonary venous anastomosis in selected cases. This technique provides the potential benefit of resolving challenging situations in which surgeons must deal with a patient's urgency and the logistical limitations of organ allocation.

Abstract
BACKGROUND Lung transplantation (LT) is a reliable therapeutic option for end-stage pulmonary lymphangioleiomyomatosis (LAM). Long-term outcome of LAM recipients after LT remains unknown. The aim of this study was to describe the outcomes of LT for LAM with a long-term follow-up, comparing those for other diseases in the same period. METHODS We retrospectively reviewed consecutive 145 LT recipients between 1998 and 2015 at Okayama University Hospital with minimum 3-year follow-up. RESULTS Twelve LAM recipients including nine sporadic-LAM and three tuberous sclerosis complex -LAM were identified. Nine of 12 underwent bilateral LT including four living-donor lobar LT. There was no significant difference in overall survival between the two groups. (P = 0.15). Chronic lung allograft dysfunction free survival rate in LAM compared with other diseases tended to be better (P = 0.058). However, the rate of requiring hemodialysis was significantly higher in LAM recipients than in the recipients of other diseases (P = 0.047). Notably, 8 of 12 (67%) LAM patients encountered LAM-related complication including chylothorax and pneumothorax, seven (58%) had proliferative diseases consisting of renal angiomyolipoma and recurrent LAM. Nine patients required mTOR inhibitors for LAM-related problems, contributing to improved control of LAM-related problems. While all nine recipients of bilateral LT have still survived, two patients died of diseases in their native lungs and one required re-LT among three recipients of single LT. CONCLUSION Although the rates of LAM-related complications were unexpectedly high in the long term, LT is a feasible therapeutic option for patients with advanced pulmonary LAM.

Abstract
OBJECTIVE In lung transplantation, unexpected pulmonary emboli, including thrombi and fat, have been observed with high probability and are associated with potential primary graft dysfunction. We evaluated a new perfusion method using warm retrograde flushing that removes more fat than conventional cold retrograde flushing. METHODS We developed a novel porcine donor model for pulmonary fat embolism by administering autologous fat in the left pulmonary artery. The left pulmonary artery and the left superior and inferior pulmonary veins were cannulated for flushing and collecting these solutions. After flushing, the left lung was reperfused under observation for 3 h. Two groups underwent warm and cold additional retrograde flush (WS; warm solution group, CS; cold solution group). RESULTS The fat removal rate in the antegrade flush was equal in both groups (3.0 ± 0.6% vs 3.0 ± 0.4%, p = 0.46); however, the rate was significantly greater in the WS group in retrograde flush (25.2 ± 3.2% vs 8.0 ± 1.4%, p = 0.01). Histology with Oil Red O staining and its software analysis showed more residual fat in the CS group (0.12 ± 0.01% vs 0.38 ± 0.07%, p = 0.01). There was no significant difference in the pulmonary function and hemodynamics during the 3-h period after reperfusion. CONCLUSION Warm retrograde perfusion can remove more fat from lung grafts with fat embolism in a porcine donor model.

Abstract
Ischemia-reperfusion injury (IRI) after lung transplantation mainly contributes to the development of primary graft dysfunction. The Sprouty-related EVH1-domain-containing (SPRED) protein family inhibits the mitogen activated protein kinase/extracellular-signal-regulated kinase (MAPK/ERK) pathway. Our study was aimed at examining the role of SPRED2 in IRI in mice that received orthotopic lung transplantation. Syngeneic mouse lung transplantation was performed in wild-type C57BL/6 J (WT) mice and Spred2 knockout (Spred2-/-) mice on the C57BL/6 J background from the WT donor. Four hours after reperfusion, blood gas analysis was performed, and lung grafts were sacrificed and analyzed. By using arterial oxygen tension measurements and histological evaluation using Lung Injury Score, we revealed more severe IRI in the grafts transplanted to Spred2-/- recipients, which manifested as exacerbated airway epithelial cell damage, interstitial edema with hemorrhage and neutrophil infiltration. Intragraft ERK1/2 activation and expression levels of proinflammatory cytokines and chemokines in Spred2-/- recipients were higher than those in WT recipients. SPRED2 plays an important role in protecting the lungs from IRI in lung transplantation recipients. We suggest that focused treatments suppressing the activity of the MAPK/ERK pathway in transplantation recipients could be the potential therapeutic option for the prevention of lung IRI.

Abstract
OBJECTIVES The role of intraoperative cardiopulmonary bypass (CPB) in lung transplant (LTx) surgery is controversial. CPB enables slow pulmonary reperfusion and initial ventilation with low oxygen concentrations, both theoretically protective of transplanted lungs. In this study, we explored clinical outcomes following extended criteria donor LTx surgery implementing a thoroughly protective allograft reperfusion strategy using CPB. METHODS Thirty-nine consecutive adult patients who underwent bilateral LTx with elective CPB and protective allograft reperfusion were reviewed. Bilaterally implanted lungs were reperfused simultaneously, via slow CPB flow reduction and initial ventilation with 21% oxygen and nitric oxide, followed by a brief modified ultrafiltration. During weaning from CPB, mean pulmonary arterial pressure was strictly maintained at 10-15 mmHg by controlling CPB and pulmonary flow. The clinical outcomes in 23 patients who received lungs from extended criteria donors (ECD group) were elucidated and compared to 16 patients undergoing LTx from standard criteria donors (SCD group). RESULTS No life-threatening deterioration was observed to graft functionality during the first 72 h after LTx in the ECD group; however, only one patient required post-transplant extracorporeal membrane oxygenation. In three of 23 ECD LTx patients (12%), surgical revision for bleeding was required. Survival outcomes for the ECD group were favorable, with 100% survival at 6-months, 87.0% at 1-year, and 80.7% at 5-years. Outcomes in the ECD group were comparable to those in the SCD group. CONCLUSIONS Despite a certain extent of risk associated with full-dose heparinization, use of CPB does not undermine survival outcomes after ECD LTx surgery if protective allograft reperfusion is securely performed.

Abstract
BACKGROUND Idiopathic pulmonary fibrosis (IPF) is a chronically progressive lung disease with exceptionally poor prognosis. While lung transplantation (LTx) is considered the last-resort therapeutic option, dismal waitlist mortality still hampers the salvage of patients with IPF. Pirfenidone, originally designed for IPF treatment, has increasingly been utilized. This study aimed to evaluate whether Pirfenidone could influence outcomes of patients with IPF on the Japanese LTx waitlist. METHODS This retrospective single-center cohort study included 25 consecutive patients with IPF who were registered as LTx candidates at our institution between July 1999 and August 2016. Patients with a history of pretransplant Pirfenidone therapy (Pirfenidone group) were compared with those with no history (non-Pirfenidone group). RESULTS In total, 6 (24%) patients received Pirfenidone as pretransplant therapy for 45.2 (range, 18.6-66.8) months. During the treatment period, the Pirfenidone group achieved a significant reduction in the decline rate of the forced vital capacity (-6.2% vs. -0.3%, p = 0.04) and a lower lung allocation score (31 vs. 41, p = 0.013) compared with the non-Pirfenidone group. The Pirfenidone group exhibited 100% waitlist survival three years after registration that was comparable to other indications, and 66% of the patients were still alive at the time of organ availability. No patient in the Pirfenidone group developed Pirfenidone-related surgical complications postoperatively. CONCLUSIONS Patients with IPF successfully managed with long-term Pirfenidone therapy achieved favorable outcomes after LTx registration, comparable to other patients with LTx indications. The tolerability to antifibrotic therapy can be a predictor of waitlist survival.

Abstract
Donor-derived cell-free DNA (dd-cf-DNA) has been shown to be an informative biomarker of rejection after lung transplantation (LT) from deceased donors. However, in living-donor lobar LT, because small grafts from blood relatives are implanted with short ischemic times, the detection of dd-cf-DNA might be challenging. Our study was aimed at examining the role of dd-cf-DNA measurement in the diagnosis of primary graft dysfunction and acute rejection early after living-donor lobar LT. Immediately after LT, marked increase of the plasma dd-cf-DNA levels was noted, with the levels subsequently reaching a plateau with the resolution of primary graft dysfunction. Increased plasma levels of dd-cf-DNA were significantly correlated with decreased oxygenation immediately (p = 0.022) and at 72 hours (p = 0.046) after LT. Significantly higher plasma dd-cf-DNA levels were observed in patients with acute rejection (median, 12.0%) than in those with infection (median, 4.2%) (p = 0.028) or in a stable condition (median, 1.1%) (p = 0.001). Thus, measurement of the plasma levels of dd-cf-DNA might be useful to monitor the severity of primary graft dysfunction, and plasma dd-cf-DNA could be a potential biomarker for the diagnosis of acute rejection after LT.

Abstract
PURPOSE Airway complications (ACs) after living-donor lobar lung transplantation (LDLLT) could have different features from those after cadaveric lung transplantation (CLT). We conducted this study to compare the characteristics of ACs after LDLLT vs. those after CLT and investigate their impact on outcomes. METHODS We reviewed, retrospectively, data on 163 recipients of lung transplantation, including 83 recipients of LDLLT and 80 recipients of CLT. RESULTS The incidence of ACs did not differ between LDLLT and CLT. The initial type of AC after LDLLT was limited to stenosis in all eight patients, whereas that after CLT consisted of stenosis in three patients and necrosis in ten patients (p = 0.0034). ACs after LDLLT necessitated significantly earlier initiation of treatment than those after CLT (p = 0.032). The overall survival rate of LDLLT recipients with an AC was significantly lower than that of those without an AC (p = 0.030), whereas the overall survival rate was comparable between CLT recipients with and those without ACs (p = 0.25). CONCLUSION ACs after LDLLT, limited to bronchial stenosis, require significantly earlier treatment and have a greater adverse impact on survival than ACs after CLT.

Abstract
Pneumatosis intestinalis, which could complicate a spectrum of clinical conditions ranging from benign to life-threatening, is a rarely encountered complication after lung transplantation (LT). We describe two cases in which PI developed as a complication following LT for pulmonary graft-versus-host disease (GVHD) after hematopoietic stem cell transplantation (HSCT). In addition to the long-term immunosuppression administered for pulmonary GVHD, the intense immunosuppression needed after LT might increase the risk of PI in lung transplant recipients after HSCT. Conservative therapy should be considered for the treatment of PI developing after LT.

Abstract
BACKGROUND Lung transplants have produced very favorable outcomes for patients with interstitial lung disease (ILD) in Japan. However, because of the severe donor lung shortage, patients must wait approximately 2.5 years before they can undergo transplantation and many candidates die before allocation. We reveal the clinical characteristics of Japanese patients with ILD who are candidates for lung transplants and the risk factors for early death while on the waiting list. METHODS We retrospectively reviewed the clinical data of patients registered in the Japan Organ Transplant Network from Okayama University Hospital who are candidates for cadaveric lung transplants for ILD between 1999 and 2015. RESULTS Fifty-three patients with ILD were included (24 patients with idiopathic pulmonary fibrosis and 29 others). They had severe pulmonary dysfunction and low exercise tolerability. The median waiting time for transplantation was 462 days, and 22 patients died before allocation. Patients who died before 462 days without undergoing transplantation had more severe dyspnea, shorter 6-minute walk distance (6MWD), and lower performance status than those who waited ≥462 days. CONCLUSIONS Japanese candidates for cadaveric lung transplants for ILD have severe pulmonary dysfunction. Severe dyspnea, short 6MWD, and low performance status are risk factors for early death while on the waiting list.

Abstract
Stent placement is an essential treatment for airway diseases. Although self-expandable metallic stents and silicone stents are commonly applied for the treatment of airway diseases, these stents are unsuitable for the treatment of small airway diseases encountered in pediatric patients and lung transplant recipients with airway complications. Currently, only vascular balloon-expandable metallic stents are available for the treatment of small airway diseases; however, little research has been conducted on the use of these stents in this field. We have launched a prospective feasibility study to clarify the safety and efficacy of balloon-expandable metallic stents for the treatment of airway diseases.

Abstract
The first case of dural metastasis occurred in a 60s years old woman, who presented with bone metastasis to the right breast. Nine months later, disorientation and left hemiplegia developed, the right coronal bone metastasis enlarged, and dural metastases were detected close to the tumor, as observed by using cranial magnetic resonance imaging (MRI). Whole brain radiation and chemotherapy(weekly paclitaxel)were administered. The right coronal bone metastasis reduced remarkably, and the dural metastases almost disappeared, as observed on a cranial MRI scan. The second case of dural metastasis occurred in a 50s years old woman who presented with multiple bone metastases. Extensive bone metastases to the skull and dural metastases to the side of the head were observed on cranial MRI scans. Subsequently, the patient experienced a severe headache, and whole brain radiation and pharmacotherapy with anastrozole and trastuzumab were administered. Cranial MRI revealed that the skull bone metastasis reduced and the dural metastases almost disappeared. We report that radiotherapy and pharmacotherapy were effective in these 2 cases of dural metastases of breast cancer.

Abstract
Monitoring the blood pump and the oxygen gas flow meter are important maneuvers at the initiation of cardiopulmonary bypass (CPB). We present a novel system, designed to improve safety in the heart-lung machine by linking the control of blood flow and the oxygen gas flow meter. This system uses a mass flow controller to provide and control oxygen flow based on the ventilation-perfusion (V/Q) ratio, using the electronic signal of the blood flow. We tested the system, in vitro and in vivo, and examined the resulting level of blood oxygenation. When extracorporeal circulation was initiated, the oxygen flow was instantly linked to the circulating blood flow, providing an adequate V/Q ratio; the partial pressure of oxygen in the blood was maintained at a normal level. Although we have yet to confirm the safety of this system in clinical trials, the new safety assist device can automatically supply oxygen to the oxygenator at the beginning of CPB.
