Congenital lobar emphysema (CLE) is defined as the hyperinflation of pulmonary lobes due to obstruction of the flow of air via a known or unknown etiology, which causes pressure symptoms in the adjacent organs. CLE is mainly diagnosed in the neonatal period, and very few adult cases have been reported. Here we report a 34-year-old male with muscular dystrophy who was diagnosed with CLE on examination. He underwent a right lower lobectomy via 3-portal completely video-assisted thoracoscopic surgery, and his symptoms improved. Thoracoscopic surgery helped preserve the respiratory muscles and led to the improvement of respiratory function in this patient.

Lung transplant recipients are often complicated by immunosuppressant-induced nephropathy, which may require renal replacement therapy. We report a case of unilateral lung edema and pulmonary hypertension due to arteriovenous fistula placement in a patient with unilateral chronic lung allograft dysfunction after bilateral living-donor lobar lung transplantation. Lung transplant recipients with limited residual vascular beds, such as lobar graft or severe deviation in lung perfusion, are vulnerable to the acute increase in blood flow due to arteriovenous fistula placement and can easily develop pulmonary edema regardless of the left ventricular function. Hence, careful volume control is required.

<title>Abstract</title><sec>
<title>Background</title>
Idiopathic multicentric Castleman disease (iMCD) is a rare polyclonal lymphoproliferative disease caused by the overrepresentation of interleukin-6 (IL-6). Tocilizumab (TCZ) is a humanized monoclonal antibody that binds to the IL-6 receptor and is approved for the treatment of iMCD. The efficacy and tolerability of TCZ in patients with iMCD undergoing lung transplantation (LTx) remain unknown.

</sec><sec>
<title>Case presentation</title>
We present the case of a 48-year-old iMCD patient with end-stage lung disease (ESLD) who was successfully treated with cadaveric single-LTx. Intravenous TCZ was used to stabilize the iMCD patient every 2 weeks, except for withdrawal immediately after LTx. At 32 month post-transplant, the patient remained asymptomatic without evidence of rejection, development of de novo donor-specific antibody (DSA), and recurrent iMCD in the native lung.

</sec><sec>
<title>Conclusions</title>
Single-LTx can be a feasible treatment option for ESLD caused by iMCD. TCZ can be used safely and may be beneficial in recipients with iMCD, and TCZ in combination with usual immunosuppression can be helpful in stabilizing iMCD patients pre- and post-LTx.

Pulmonary enteric adenocarcinoma (PEAC) is a rare subtype of lung cancer that should be differentiated from colorectal cancer metastasis. Little is known about its genetic background. An 84-year-old male with adenocarcinoma of the lung underwent left upper lobectomy. The histology of the surgical specimen was suggestive of PEAC. Gastrointestinal and colorectal fiberscopy revealed no evidence of colorectal cancer. Next-generation sequencing of the tumor identified a G469V substitution in serine/threonine-protein kinase B-raf (BRAF). Based on the higher prevalence of the G469 substitution in BRAF-mutant lung adenocarcinoma than in BRAFmutant colorectal cancer, the tumor likely originated from the lung. Identification of mutational genotype may be of some help in distinguishing PEAC from the lung metastasis of colorectal cancer.

OBJECTIVE: Although living-donor lobar lung transplantation (LDLLT) enables an intermediate survival similar to cadaveric lung transplantation, the long-term outcome remains unknown. We examined the long-term outcomes of 30 patients who received LDLLT more than 16 years previously. METHODS: We retrospectively reviewed the clinical data of 30 patients who underwent LDLLT (bilateral LDLLT, 29 patients; single LDLLT, 1 pediatric patient) between October 1998 and April 2004. RESULTS: LDLLT was performed for 25 female and 5 male patients ranging in age from 8 to 55 years. The diagnoses included pulmonary hypertension (n = 11), pulmonary fibrosis (n = 7), bronchiolitis obliterans (n = 5), and others (n = 7). At a median follow-up of 205 months, 22 patients were alive and 8 were dead. The causes of death were infection (n = 3), malignancy (n = 2), acute rejection (n = 2), and chronic lung allograft dysfunction (CLAD; n = 1). Unilateral CLAD occurred in 17 patients (56.7%), but only 1 of these patients subsequently developed bilateral CLAD. Two patients underwent bilateral cadaveric lung retransplantations. The 5-, 10-, and 15-year CLAD-free survival rates were 80.0%, 62.8%, and 44.3%, respectively. Malignancy occurred in 7 patients. Two of 5 patients with chronic kidney disease requiring hemodialysis underwent living-donor kidney transplantation. The 5-, 10-, and 15-year overall survival rates were 96.7%, 86.7%, and 73.3%, respectively. CONCLUSIONS: Although only 2 lobes are implanted, LDLLT provides encouraging long-term outcomes. In patients with unilateral CLAD, the functioning contralateral graft might contribute to a favorable long-term outcome.

PURPOSE: Post-transplant lymphoproliferative disorder (PTLD) is a major complication of lung transplantation (LTx). However, few studies on PTLD in Asian populations have been reported. We explored the characteristics of Japanese PTLD cases after LTx. METHODS: We retrospectively reviewed 195 cases of LTx at our institute. We summarized the clinical experiences of 7 PTLD cases and analyzed the patient characteristics and survival outcomes of patients with (n = 7) and without (n = 188) PTLD. RESULTS: All PTLD patients were taking corticosteroids preoperatively (p = 0.0030), and the duration of preoperative corticosteroid therapy was significantly longer in the PTLD group (p = 0.0064) than in the non-PTLD group. The overall survival after LTx was significantly worse in the PTLD group (p = 0.027) than in the non-PLTD group. Among the three patients who died within 1 year after the PTLD onset, two died of opportunistic infections without residual PTLD lesions. Chronic lung allograft dysfunction (CLAD) or bronchiolitis obliterans at an autopsy were diagnosed after PTLD treatment in four cases. CONCLUSIONS: Long-term preoperative corticosteroid therapy may be a risk factor for PTLD after LTx. Opportunistic infections are lethal complications of PTLD, regardless of the effectiveness of PTLD treatment. CLAD occurs at a high rate after PTLD treatment, and close monitoring is required.

Background: Massive blood transfusion compensating hemorrhage during lung transplantation (LT) results in primary graft dysfunction (PGD) and worse outcomes after LT. Collateral vessels in the perihilar mediastinal pleura could be the source of hemorrhage during LT in patients with pulmonary hypertension (PH). The purpose of this study was to examine the effect of closure with hemoclips of the vessels in the perihilar mediastinal pleura on the risk of intraoperative hemorrhage and outcomes after LT in patients with PH. Methods: We retrospectively reviewed 80 patients who underwent LT, including 13 patients with primary PH, 29 patients with secondary PH, and 38 patients with non-PH. Results: The median number of hemoclips was significantly higher in the primary PH group than in the non-PH group (P=0.0045) or secondary PH group (P=0.0060). The intraoperative blood loss, transfusion volume, maximum PGD grade, and the 30-day and 90-day mortality rates in the primary PH group were equivalent to those in the other two groups. Conclusions: Meticulous closure of collateral vessels in the perihilar mediastinal pleura during LT in patients with primary PH allowed intraoperative hemorrhage to be controlled and might be associated with acceptable mortality rate in these patients similar to that of LT in patients with other diseases.

PURPOSE: The prognostic nutritional index (PNI), calculated based on the serum albumin levels and the total lymphocyte count, has been identified as a predictor of clinical outcomes in various fields of surgery. In this study, we investigated the relationship between the PNI and the lung allocation score (LAS) as well as the impact of the PNI on the outcomes of both cadaveric lung transplantation (CLT) and living-donor lobar lung transplantation (LDLLT). METHODS: We reviewed retrospective data for 127 recipients of lung transplantation (LT), including 71 recipients of CLT and 56 recipients of LDLLT. RESULTS: The PNI was correlated significantly and negatively with the LAS (r = - 0.40, P = 0.0000037). Multivariate analysis revealed that age (P = 0.00093), BMI (P = 0.00087), and PNI (P = 0.0046) were independent prognostic factors of a worse outcome after LT. In a subgroup analysis, survival after both CLT (P = 0.015) and LDLLT (P = 0.041) was significantly worse in the low PNI group than in the high PNI group. CONCLUSION: Preoperative nutritional evaluations using the PNI can assist with the assessment of disease severity in LT recipients and may predict survival after both CLT and LDLLT.
