Abstract
OBJECTIVE For small-sized recipients of lung transplantation, the time span for organ reception from standard donors is generally longer than for normal-sized patients. Despite its underuse, lobar reduction may be a concrete option for these patients. This study aims to assess early and long-term outcomes associated with lobar reduction in lung transplantation. METHODS A retrospective study was performed on 608 consecutive lung transplantations at 2 centers between January 2005 and August 2019 (559 standard lung transplantations [standard transplantation] and 49 with lobar reduction [lung transplantation group]). A propensity-score weighting approach was used to account for potential confounding related to patients' nonrandom allocation to the 2 intervention groups. The effects of the intervention on postoperative outcomes were assessed with a weighted regression approach. RESULTS The propensity score was estimated on 571 patients (522 in standard transplantation group and 49 in lung transplantation group). In terms of early outcomes, the lung transplantation group showed a higher percentage of severe primary graft dysfunction at 0 hours and reported longer intensive care unit stay than the standard transplantation group. No other differences in terms of morbidity, mortality, mechanical ventilation time, hospital stay, and anastomotic complications were observed. Although the lung transplantation group showed worse long-term pulmonary function, the 2 populations had comparable survival outcomes. CONCLUSIONS The use of lobar reduction showed early and long-term results comparable to those after standard lung transplantation. Although a higher rate of early severe primary graft dysfunction and slightly reduced respiratory function were detected in the lobar group, these did not affect patients' morbidity and survival.

Santos Silva J, Olland A, Massard G, Falcoz PE. Does lobar or size-reduced lung transplantation offer satisfactory early and late outcomes? Interact Cardiovasc Thorac Surg 2021; 31:93-97. [PMID: 32588059 DOI: 10.1093/icvts/ivaa051] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2019] [Revised: 07/09/2019] [Accepted: 02/26/2020] [Indexed: 11/15/2022] Open
Abstract
A best evidence topic was constructed according to a structured protocol. The question addressed was whether size-reduced or lobar lung transplantation (LLTx) offers the same benefit as classic lung transplantation (LTx). Of the 147 papers found using the reported search, 9 were selected to provide the best evidence. Details of the studies regarding authors, date, journal, country of publication, study type, group studied, relevant outcomes and results are given. All studies reported survival rates of LLTx and most compared it with classical LTx. No statistical differences were reported in medium term and long term. Two of the studies reported a higher incidence of postoperative complications, such as the need for cardiopulmonary bypass, reperfusion oedema or primary graft dysfunction, and longer intubation or intensive care unit stay times. Although the largest study showed a significantly worse 1-year survival in LLTx, a sub-analysis considering patients successfully discharged showed similar outcomes at 1, 3 and 5 years when compared with classic LTx patients. We conclude that LLTx is a valid therapeutic option for recipients with significant donor size mismatch, offering similar outcomes as classical LTx in the medium term and long term.

Lobar lung transplantation from deceased donors: A systematic review. World J Transplant 2017; 7:70-80. [PMID: 28280698 PMCID: PMC5324031 DOI: 10.5500/wjt.v7.i1.70] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/30/2016] [Revised: 08/12/2016] [Accepted: 12/28/2016] [Indexed: 02/05/2023] Open
Abstract
AIM To systematically review reports on deceased-donor-lobar lung transplantation (ddLLTx) and uniformly describe size matching using the donor-to-recipient predicted-total lung-capacity (pTLC) ratio.
METHODS We set out to systematically review reports on ddLLTx and uniformly describe size matching using the donor-to-recipient pTLC ratio and to summarize reported one-year survival data of ddLLTx and conventional-LTx. We searched in PubMed, CINAHL via EBSCO, Cochrane Database of Systematic Reviews via Wiley (CDSR), Database of Abstracts of Reviews of Effects via Wiley (DARE), Cochrane Central Register of Controlled Trials via Wiley (CENTRAL), Scopus (which includes EMBASE abstracts), and Web of Science for original reports on ddLLTx.
RESULTS Nine observational cohort studies reporting on 301 ddLLTx met our inclusion criteria for systematic review of size matching, and eight for describing one-year-survival. The ddLLTx-group was often characterized by high acuity; however there was heterogeneity in transplant indications and pre-operative characteristics between studies. Data to calculate the pTLC ratio was available for 242 ddLLTx (80%). The mean pTLCratio before lobar resection was 1.25 ± 0.3 and the transplanted pTLCratio after lobar resection was 0.76 ± 0.2. One-year survival in the ddLLTx-group ranged from 50%-100%, compared to 72%-88% in the conventional-LTx group. In the largest study ddLLTx (n = 138) was associated with a lower one-year-survival compared to conventional-LTx (n = 539) (65.1% vs 84.1%, P < 0.001).
CONCLUSION Further investigations of optimal donor-to-recipient size matching parameters for ddLLTx could improve outcomes of this important surgical option.

Abstract
Five articles and an editorial on interventional pneumology were published in Archivos de Bronconeumología. Two of these articles deal with bronchoscopy, one with lung biopsy with cryoprobes, one with thermoplasty in asthma and the last with tracheobronchomalacia. We also review several publications in international journals, with special emphasis on endobronchial ultrasound. Four original articles on idiopathic pulmonary fibrosis were published in Archivos de Bronconeumología: one special article comparing two treatments and a Cochrane systematic review on the efficacy of non-steroidal drugs in this disease. Finally, we highlight studies in lung transplantation, consisting of 14 publications from different continents and with highly diverse contents: one editorial, one letter to the editor, one procedures manual and nine international publications on donor characteristics, various types of complications, experimental results in the field of preservation, and the casuistics obtained in distinct diseases in which transplantation is an option.

Abstract
OBJECTIVES We report our experience of lobar lung transplantations (LLTs) in patients with small thoracic volume. METHODS Since 1988, 50 LLTs were done for cystic fibrosis (n=35), fibrosis (n=7), bronchiectasis (n=3), emphysema (n=3) and lymphangiomyomatosis (n=2). There were 44 females and 6 males (mean age 31±13 years, mean size 155±5.5 cm and mean predicted total lung capacity (TLC) 4463±598 ml). Mean ratio between donor and recipient-predicted TLC was 1.65±0.26. Six patients were listed in high emergency, 2 of them on ECMO as a bridge to transplantation. Forty middle/lower right lobe with left lower LLT, four bilateral lower LLT and six split left lung LLT were performed through a clamshell incision (n=12) or a bilateral antero-lateral thoracotomy (n=38), with epidural analgesia in 17 cases. Thirty-two patients were transplanted under circulatory support (CPB n=16, veno-arterial ECMO n=16). In 11 cases, the right venous anastomosis was enlarged by a pericardial cuff. Ischaemic time was 4.4±1.2 h for the first lobe and 6.1±1.3 h for the second. RESULTS Median mechanical ventilation weaning time was 10.5 (1-136) days. Four patients were extubated in the operating room. Ten patients needed ECMO for primary graft dysfunction. In-hospital mortality was 28% related to sepsis (n=6), PGD (n=3), haemorrhage (n=2), broncho-vascular fistula (n=1), and multiorgan failure (n=2). Eight patients required endoscopic treatments for airway complications. Mean best FEV1 was 72±16% of the theoretical value. The actuarial 3-year and 5-year survival rates were 60 and 46%, respectively. CONCLUSIONS LLTs are a reliable solution and can be performed with satisfactory functional results and survival rates.

Abstract
Lung transplantation is a well-established treatment option for selected patients with end-stage lung disease, leading to improved survival and improved quality of life. The last 20 years have seen a steady growth in number of lung transplantation procedures performed worldwide. The increase in clinical activity has been associated with tremendous progress in the understanding of cellular and molecular processes that limit both short- and long-term outcomes. This review gives a comprehensive overview of the current status of lung transplantation for the referring physician. It demonstrates that careful selection of potential recipients, optimisation of their condition prior to transplant, use of carefully assessed donor organs, excellent surgery and meticulous long-term follow-up are all essential ingredients in determining a successful outcome.

Abstract
Among patients with end-stage lung disease awaiting lung transplantation, pediatric and small adult patients have a significantly lower chance of getting size-matched pulmonary grafts in time because of the severe scarcity of small donors. It is our strategy to perform lobar lung transplantations in small recipients with restrictive pulmonary disease once their clinical status demands urgent transplantation. Here we describe our surgical technique and discuss the benefits and risks of this procedure.
