RESUMO
OBJECTIVE: To describe our experience with lung transplantation (LTx) from donors ≥70 years and compare short and long-term outcomes to a propensity-matched cohort of donors <70 years. BACKGROUND: Although extended-criteria donors have been widely used to enlarge the donor pool, the experience with LTx from older donors (≥70 years) remains limited. METHODS: All single-center bilateral LTx between 2010 and 2020 were retrospectively analyzed. Matching (1:1) was performed for the donor (type, sex, smoking history, x-ray abnormalities, partial pressure of oxygen/fraction of inspired oxygen ratio, and time on ventilator) and recipient characteristics (age, sex, LTx indication, perioperative extracorporeal life support, and cytomegalovirus mismatch). Primary graft dysfunction grade-3, 5-year patient, and chronic lung allograft dysfunction-free survival were analyzed. RESULTS: Out of 647 bilateral LTx, 69 were performed from donors ≥70 years. The mean age in the older donor cohort was 74 years (range: 70-84 years) versus 49 years (range: 12-69 years) in the matched younger group. No significant differences were observed in the length of ventilatory support, intensive care unit, or hospital stay. Primary graft dysfunction-3 was 26% in the older group versus 29% in younger donor recipients ( P = 0.85). Reintervention rate was comparable (29% vs 16%; P = 0.10). Follow-up bronchoscopy revealed no difference in bronchial anastomotic complications ( P = 1.00). Five-year patient and chronic lung allograft dysfunction-free survivals were 73.6% versus 73.1% ( P = 0.72) and 51.5% versus 59.2% ( P = 0.41), respectively. CONCLUSIONS: LTx from selected donors ≥70 years is feasible and safe, yielding comparable short and long-term outcomes in a propensity-matched analysis with younger donors (<70 years).

BACKGROUND: Esophageal cancer surgery outcomes benefit from higher hospital volumes. Despite the evidence, organization of national health care often is complex and depends on various factors. The volume-outcome results of this population-based study supported national health policy measures regarding concentration of esophageal resections in Belgium. METHODS: The Belgian Cancer Registry (BCR) database was linked to administrative data on cancer treatment. All Belgian patients with newly diagnosed esophageal cancer in 2008-2018 undergoing resection were allocated to the hospital at which surgery was performed. The study assessed hospital volume association with 90-day mortality and 5-year overall survival, classifying average annual hospital volume of resections as low (LV, <6), medium (MV, 6-19), or high (HV, ≥20) and as a continuous covariate in the regression models. RESULTS: The study included 4156 patients who had surgery in 79 hospitals (2 HV hospitals [37% of all surgeries], 12 MV hospitals [30% of all surgeries], and 65 LV hospitals [33% of all surgeries]). Adjusted 90-day mortality in HV hospitals was lower than in LV hospitals (odds ratio [OR], 0.37; 95% CI, 0.21-0.65; p = 0.001). Case-mix adjusted 5-year survival was superior in HV versus LV (hazard ratio [HR], 0.43; 95% CI, 0.31-0.60; p < 0.001). The continuous model demonstrated a lower 90-day mortality (OR, 0.40; 95% CI, 0.23-0.71; p = 0.002) and a superior 5-year survival (HR, 0.45; 95% CI, 0.33-0.63; p < 0.001) in hospitals with volumes of 40 or more resections annually. CONCLUSION: Population-based data from the BCR confirmed a strong volume-outcome association for esophageal resections. Improved 5-year survival in centers with annual volumes of 20 or more resections was driven mainly by the achievement of superior 90-day mortality. These findings supported centralization of esophageal resections in Belgium.

BACKGROUND: Different surgical techniques exist in the treatment of giant and complex hiatal hernia. The aim of this study was to identify the role of the Belsey Mark IV (BMIV) antireflux procedure in the era of minimally invasive techniques. METHODS: A single-center, retrospective cohort study was conducted. All patients who underwent an elective BMIV procedure aged 18 years or older, during a 15-year period (January 1, 2002 until December 31, 2016), were included. Demographics, pre-, per- and postoperative data were analyzed. Three groups were compared. Group A: BMIV as first procedure-group B: BMIV as a second procedure (first redo intervention)-group C: patients who had two or more previous antireflux interventions. RESULTS: A total of 216 patients were included for analysis (group A n = 127; group B n = 51; group C n = 38). Median follow-up in groups A, B and C was 28, 48 and 56 months, respectively. Patients in group A were older and had a higher American Society of Anesthesiologists score compared to groups B and C. There was zero mortality in all groups. The severe complication rate of 7.9% in group A was higher compared with the 2.9% in group B and 3.9% in group C. Long-term outcome showed true recurrence, defined as both radiographic recurrence as well as associated symptoms, in 9.5% of cases in group A, 24.5% in group B and 44.7% in group C. CONCLUSIONS: The BMIV procedure is a safe procedure with good results, moreover in the aging and comorbid patient with primary repair of a giant hiatal hernia.

Anastomotic leakage after esophagectomy is one of the most feared complications, which results in increased morbidity and mortality. Our aim was to evaluate the impact of a powered circular stapler on complications after esophagectomy with intrathoracic anastomosis for esophageal cancer. Between May 2019 and July 2021, all consecutive oesophagectomies for cancer with intrathoracic anastomosis in a high-volume center were included in this retrospective study. Surgeons were free to choose either a manual or a powered circular stapler. Preoperative characteristics and postoperative complications were recorded in a prospective database, according to EsoData. Propensity score matching (age, body mass index, Eastern cooperative oncology group (ECOG) performance and neoadjuvant therapy) was conducted to reduce potential confounding. We included 128 patients. Powered and manual circular staplers were used in 62 and 66 patients, respectively. Fewer anastomotic leakages were observed with the powered stapler group (OR = 7.3 (95%CI: 1.58-33.7); [3.2% (n = 2) vs 19.7% (n = 13), respectively; p = 0.004]). After propensity score matching, this remained statistically significant (OR = 8.5 (95%CI: 1.80-40.1); [4.1% (n = 2) vs 20.4% (n = 10), respectively; p = 0.013]). Additionally, anastomotic diameter was significantly higher with the powered stapler (median: 29 mm (63.3%) vs 25 mm (57.1%), respectively; p < 0.0001). There was no significant difference in comprehensive complication index (p = 0.146). A decreased mean length of stay was observed in the powered stapler group (11.1 vs 18.7 days respectively; p = 0.022). Postoperative anastomotic leakage after esophageal resection was significantly reduced after the introduction of the powered circular stapler, consequently resulting in a reduced length of stay. Further evaluation on long-term strictures and quality of life are warranted to support these results.

BACKGROUND: Due to the SARS-COV2 pandemic-related restrictions the 2020 Belgian Surgical Week (BSW) was organized as a virtual congress, being the first surgical, virtual congress in Belgium. Since this was a new experience and probably not the last, we aim to share our experience to assist other professionals in organizing their virtual events. METHODS: The 'BSW-light' was organized by the RBSS in collaboration with a Professional Congress Organizer (PCO), which is described in detail. Analytical data of the event were provided by the PCO and a UEMS 'live educational events participant evaluation form' based survey was sent out to all registered participants, using google forms, to evaluate the event. RESULTS: During 2 days, 78 prerecorded presentations were broadcasted in 2 virtual conference rooms, each followed by a live Q & A session. The plenary session on the third day contained 8 live presentations, both from Belgium and from abroad. A total of 503 people registered for the congress, of whom 224 trainees. Each session attracted 158 visitors on average, each spending an average of 73 min. Attendees were satisfied with the technical aspect of the virtual congress, but they preferred an event that is at least partially live. CONCLUSION: Although the 'BSW-light' proved to be successful, a preference to meet in real life remained. However, given its potential, we should keep an open mind towards integrating the advantages of a virtual meeting into a live event.

Primary graft dysfunction (PGD) is a major obstacle after lung transplantation (LTx), associated with increased early morbidity and mortality. Studies in liver and kidney transplantation revealed prolonged anastomosis time (AT) as an independent risk factor for impaired short- and long-term outcomes. We investigated if AT during LTx is a risk factor for PGD. In this retrospective single-center cohort study, we included all first double lung transplantations between 2008 and 2016. The association of AT with any PGD grade 3 (PGD3) within the first 72 h post-transplant was analyzed by univariable and multivariable logistic regression analysis. Data on AT and PGD was available for 427 patients of which 130 (30.2%) developed PGD3. AT was independently associated with the development of any PGD3 ≤72 h in uni- (odds ratio [OR] per 10 min 1.293, 95% confidence interval [CI 1.136-1.471], p < .0001) and multivariable (OR 1.205, 95% CI [1.022-1.421], p = .03) logistic regression analysis. There was no evidence that the relation between AT and PGD3 differed between lung recipients from donation after brain death versus donation after circulatory death donors. This study identified AT as an independent risk factor for the development of PGD3 post-LTx. We suggest that the implantation time should be kept short and the lung cooled to decrease PGD-related morbidity and mortality post-LTx.

Parenteral nutrition (PN) is recommended in patients nutritionally at risk and unable to receive oral or enteral nutrition. A standardized electronic PN order format could enhance appropriate PN prescribing. We developed the OLIVE TREE (Offering guidance and Learning to prescribers to Initiate PN using a Validated Electronic decision TREE), embedded in our electronic health record. We aimed to evaluate its validity and impact on physicians' prescribing behavior. A non-randomized before-after study was carried out in a tertiary care center. The OLIVE TREE comprises 120 individual items. A process validation was performed to determine interrater agreement between a pharmacist and the treating physician. To estimate the proportion of patients for whom the OLIVE TREE had an effective and potential impact on physicians' prescribing behavior, a proof of concept study was conducted. The proportion of patients for whom PN was averted and the proportion of decisions not in line with the recommendation were also calculated. The process validation in 20 patients resulted in an interrater agreement of 95.0%. The proof of concept in 73 patients resulted in an effective and potential impact on prescribing behavior in 50.7% and 79.5% of these patients, respectively. Initiation of PN was not averted and recommendations of the OLIVE TREE were overruled in 42.5% of the patients. Our newly developed OLIVE TREE has a good process validity. A substantial impact on prescribing behavior was observed, although initiation of PN was not avoided. In the next phase, the decision tree will be implemented hospital-wide.

BACKGROUND: Belgium was one of the first European countries affected by the first wave of the Covid-19 epidemic after Italy and France and has the highest rate of Covid-19-related deaths. Very few studies have evaluated the impact of the pandemic on surgical activity on a large scale. The primary objective of this national survey was to evaluate the impact of the first wave of the Covid-19 pandemic on surgical activities (elective non-oncological and oncological) in Belgian hospitals. METHODS: A nationwide, multicenter survey was conducted in Belgium by the Royal Belgian Surgical Society (RBSS) board. The questionnaire focused on digestive surgical activity at different time points: period 1 (P1), before the epidemic; period 2 (P2), lockdown; and period 3 (P3), after stabilization of the epidemic. RESULTS: The participation rate in the survey was 28.2% (24 out of 85 solicited hospitals), including 15 (62.5%) from the French speaking part of Belgium and 9 (37.5%) from the Flemish speaking part. Eighteen (75%) were non-academic and 6 (25%) were academic hospitals. All surgical activities were impacted by the Covid-19 pandemic except for the number of cholecystectomies. No statistical differences were observed between regions or according to the type of hospital. CONCLUSIONS: Our national survey confirms that the COVID-19 outbreak has severely impacted in-person consultations and surgical activity for benign and malignant disease and for acute appendicitis. However, procedures for benign disease were much more affected than those for malignancies.

The optimal perioperative fluid management during esophagectomy is still not clear. Liberal regimens have been associated with higher morbidity and respiratory complications. Restrictive regimens might raise concerns for kidney function and increase the need to associate vasopressors. The aim of this study was to investigate retrospectively the perioperative fluid administration during esophagectomy and to correlate this with postoperative respiratory outcome. All patients who underwent esophagectomy between January and December 2016 were retrospectively analyzed. Patient characteristics, type of surgery and postoperative course were reviewed. Fluid administration and vasopressor use were calculated intraoperatively and during the postoperative stay at the recovery unit. Fluid overload was defined as a positive fluid balance of more than 125 mL/m2/h during the first 24 hours. Patients were divided in 3 groups: GRP0 (no fluid overload/no vasopressors); GRP1 (no fluid overload/need for vasopressors); GRP2 (fluid overload with/without vasopressors). Postoperative complications were prospectively recorded according to Esophagectomy Complications Consensus Group criteria. A total of 103 patients were analyzed: 35 (34%) GRP0, 50 (49%) GRP1 and 18 (17%) GRP2. No significant differences were found for age, treatment (neoadjuvant vs. primary), type of surgery (open/minimally invasive), histology nor comorbidities. There were significant (P ≤ 0.001) differences in fluid balance/m2/h (75 ± 21 mL; 86 ± 22 mL and 144 ± 20 mL) across GRP0, GRP1 and GRP2, respectively. We found differences in respiratory complications (GRP0 (20%) versus GRP1 (42%; P = 0.034) and GRP0 (20%) versus GRP2 (61%; P = 0.002)) and "Comprehensive Complications Index" (GRP0 (20.5) versus GRP1 (34.6; P = 0.015) and GRP0 (20.5) versus GRP2 (35.1; P = 0.009)). Multivariable analysis (binary logistic regression) for "any respiratory complication" was performed. Patients who received fluid overload (GRP2) had a 10.24 times higher risk to develop postoperative respiratory complications. When patients received vasopressors alone (GRP1), the chances of developing these complications were 3.57 times higher compared to GRP0. Among patients undergoing esophagectomy, there is a wide variety in the administration of fluid during the first 24 hours. There was a higher incidence of respiratory complications when patients received higher amounts of fluid or when vasopressors were used. We believe that a personalized and protocolized fluid administration algorithm should be implemented and that individual risk factors should be identified.

The technique for bronchial stump suturing following lung resection which is currently applied in the Department of Thoracic Surgery at the University Hospitals Leuven, Belgium owes its name to the Dutch surgeon Dr. Klinkenbergh (1891-1985). A true pioneer of cardiothoracic surgery in Europe, Dr. Klinkenbergh dedicated himself to the surgical treatment of pulmonary tuberculosis. His work was praised by his peers for his precision and the reasoning behind every gesture. The Klinkenbergh technique consists in performing two running sutures which cross each other 'in the same manner as the laces of a shoe' to close the bronchus, limiting the occurrence of broncho-pleural fistulas. In our experience with more than 100 patients in the last 5 years (2016-2020) who underwent open pneumonectomy for benign or malignant disease, less than 2% developed post-operative broncho-pleural fistulas.

AIMS: In thymic carcinomas, focal clear cell change is a frequent finding. In addition to a prominent, diffuse clear cell morphology, some of these carcinomas show an exuberant hyalinised extracellular matrix, and therefore probably represent a separate entity. However, a characteristic genomic alteration remains elusive. We hypothesised that, analogous to hyalinising clear cell carcinomas of the salivary gland, hyalinising clear cell carcinomas of the thymus might also harbour EWSR1 translocations. METHODS AND RESULTS: We identified nine archived cases of thymic carcinoma with focal clear cell features and two cases that showed remarkable hyalinised stroma and prominent, diffuse clear cell morphology. These two cases expressed p40 and were negative for Pax8, CD5, and CD117. Programmed death-ligand 1 was highly positive in one case (70%), and negative in the other one. EWSR1 translocation was identified in both cases of hyalinising clear cell carcinoma, and was absent in all nine carcinomas that showed clear cell features without substantial hyalinisation. In one of the EWSR1-translocated cases, a fusion between exon 13 and exon 6 of EWSR1 and ATF1, respectively was identified by next-generation sequencing. CONCLUSIONS: These findings suggest that the EWSR1 translocation and possibly the EWSR1-ATF1 fusion might be unifying genomic alterations for thymic clear cell carcinomas with prominent hyalinised stroma, for which we propose the term 'hyalinising clear cell carcinoma of the thymus'. Because the immunophenotype is unspecific, testing for the EWSR1 translocation might be helpful in discriminating this entity from other thymic neoplasms or metastases, in particular those with clear cell change.

Transplant type for end-stage pulmonary vascular disease remains debatable. We compared recipient outcome after heart-lung (HLT) versus double-lung (DLT) transplantation. Single-center analysis (38 HLT-30 DLT; 1991-2014) for different causes of precapillary pulmonary hypertension (PH): idiopathic (22); heritable (two); drug-induced (nine); hepato-portal (one); connective tissue disease (four); congenital heart disease (CHD) (24); chronic thromboembolic PH (six). HLT decreased from 91.7% [1991-1995] to 21.4% [2010-2014]. Re-intervention for bleeding was higher after HLT; (P = 0.06) while primary graft dysfunction grades 2 and 3 occurred more after DLT; (P < 0.0001). Graft survival at 90 days, 1, 5, 10, and 15 years was 93%, 83%, 70%, 47%, and 35% for DLT vs. 82%, 74%, 61%, 48%, and 30% for HLT, respectively (log-rank P = 0.89). Graft survival improved over time: 100%, 93%, 87%, 72%, and 72% in [2010-2014] vs. 75%, 58%, 42%, 33%, and 33% in [1991-1995], respectively; P = 0.03. No difference in chronic lung allograft dysfunction (CLAD)-free survival was observed: 80% & 28% for DLT vs. 75% & 28% for HLT after 5 and 10 years, respectively; P = 0.49. Primary graft dysfunction in PH patients was lower after HLT compared to DLT. Nonetheless, overall graft and CLAD-free survival were comparable and improved over time with growing experience. DLT remains our preferred procedure for all forms of precapillary PH, except in patients with complex CHD.

BACKGROUND: Neoadjuvant treatment followed by esophagectomy is standard practice in locally advanced esophageal cancer. However, not all patients who started neoadjuvant treatment will undergo esophageal resection. The purpose of our study was to investigate the group of patients, scheduled for neoadjuvant treatment followed by esophagectomy, who never made it to esophageal resection. METHODS: We retrospectively analyzed patients treated between 2002 and 2015 for locally advanced esophageal cancer, who did not undergo esophagectomy after neoadjuvant treatment. Subanalysis was performed according to time period (2002-2010 versus 2011-2015) and histology (adenocarcinoma versus squamous cell carcinoma). RESULTS: In 114 of 679 patients (16.8%), surgery was not performed after neoadjuvant treatment. Reasons for cancelation were disease progression (50 patients, 43.9%), poor general condition (26 patients, 22.8%), irresectability (14 patients, 12.3%), patients' own decision (15 patients, 13.2%), and death during neoadjuvant treatment (9 patients, 7.9%). In the second time period, there were less irresectable tumors (17.7% versus 5.8%; p = 0.044). Median overall survival was not different over time (9.2 versus 12.5 months; p = 0.937). Irresectability (p = 0.032), patients' refusal (p = 0.012), and poor general condition (p = 0.002) were more frequent as reasons for cancelation in squamous cell carcinoma patients. Median overall survival was, respectively, 12.5 and 9.9 months for adenocarcinoma and squamous cell carcinoma patients (p = 0.441). The majority of patients refusing surgery had a clinical complete response (73.3%). They had a median overall survival of 33.2 months. CONCLUSIONS: One in six patients starting neoadjuvant treatment for locally advanced esophageal cancer never made it to esophagectomy, more than half of them for oncological reasons, but also 1.3% because of death during treatment. Over time, irresectability as reason decreased. As a result, the relative weight of medical inoperability increased, indicating the importance of upfront testing of medical operability. Cancelation of surgery was significantly more common in patients with a squamous cell carcinoma, and this histology seems to represent a more complex oncological and functional entity. Refusal of esophagectomy based on clinical complete response showed a significant survival benefit compared to those who did not undergo esophagectomy because of other reasons.

INTRODUCTION: A new hypermetabolic lesion on 18FDG-PET/CT after neo-adjuvant chemoradiotherapy for distal esophageal cancer can be a hepatic metastasis and should be examined carefully before esophagectomy. CASE-REPORT: We present a case of acute and nodular radiation-induced injury of the left liver after neo-adjuvant chemoradiotherapy for distal esophageal cancer, which resembles a hepatic metastasis on 18FDG-PET/CT. Acute and nodular radiation hepatitis (RH) can be a potential cause of false-positive findings of malignancy and therefore exclude patients who could benefit from esophagectomy. CONCLUSION: 18FDG-PET/CT images should therefore carefully be interpreted and compared with the radiation beams, dose distribution and eventually clarified by DW-MR imaging.

Esophageal wall rupture after EUS-FNA for mediastinal staging is a severe complication. Here we describe the management of two patients with esophageal wall rupture and the presence of empyema. Management was in both cases surgical and consisted of a decortication via thoracotomy. Postoperative IV antibiotics and parenteral nutrition were continued until the first negative X-ray with gastrografin. Both patients recovered and left the hospital in good condition and with oral intake.

Despite a worldwide need to expand the lung donor pool, approximately 75% of lung offers are not accepted for transplantation. We investigated the impact of liberalizing lung donor acceptance criteria during the last decade on the number of effective transplants and early and late outcomes in our center. All 514 consecutive lung transplants (LTx) performed between Jan 2000 and Oct 2011 were included. Donors were classified as matching standard criteria (SCD; n = 159) or extended criteria (ECD; n = 272) in case they fulfilled at least one of the following criteria: age >55 years, PaO2 /FiO2 at PEEP 5 cmH2 O < 300 mmHg at time of offer, presence of abnormalities on chest X-ray, smoking history, presence of aspiration, presence of chest trauma, or donation after circulatory death. Outcome parameters were primary graft dysfunction (PGD) grade at 0, 12, 24, and 48 h after LTx, time to extubation, stay in intensive care unit (ICU), early and late infection, acute rejection and bronchiolitis obliterans syndrome (BOS), and survival. Two hundred and seventy-two recipients (63.1%) received ECD lungs. PGD grade at T0 was similar between groups, while at T12 (<0.01), T24 (<0.01), and T48 (<0.05), PGD3 was observed more often in ECDs. ICU stay (P < 0.05) was longer in ECDs compared with SCDs. Time to extubation, respiratory infections, acute rejection, lymphocytic bronchiolitis, BOS, and survival were not different between groups. Accepting ECDs contributed in increasing the number of lung transplants performed in our center. Although this lung donor strategy has an impact on early postoperative outcome, liberalizing criteria did not influence long-term outcome after LTx.

OBJECTIVE: To clarify the biologic behavior of esophageal signet ring cell (SRC) carcinomas of the esophagus and gastroesophageal junction (GEJ). To evaluate the accuracy of pretreatment biopsies in diagnosing true SRC carcinoma. BACKGROUND: In contrast with gastric cancer, little is known about the biologic behavior and prognosis of SRC. METHODS: All adenocarcinomas (ADC) of the esophagus and GEJ-patients undergoing primary resection between 1990 and 2009 were included (n = 920). Specimens containing SRCs (n = 114) were classified according to World Health Organization criteria (>50% SRC or <50% SRC). RESULTS: Thirty-two patients showed more than 50% SRC and 71 patients showed less than 50% SRC. Overall cancer-specific 5-year survival was worse for SRC (22.4%, P < 0.0001) and for SRC > 50% (13.6%, P = 0.0001) compared with ADC. Complete resection was achieved in 86.5% of patients (n = 697) in ADC, 69.5% (n = 57) in SRC < 50%, and 78.1% (n = 25) in SRC > 50% (vs ADC, respectively, P < 0.0001 and P = 0.1801). In 379 pN + R0 patients, the median number of positive lymph nodes was comparable between ADC and SRC < 50% (4 vs 5, P = 0.207) or SRC > 50% (4 vs 8, P = 0.077). Compared with ADC, SRC > 50% showed more pN3's (30% vs 61%, P = 0.006), higher recurrence (56% vs 42% for ADC, P = 0.003), and local-regional recurrences (29% vs 16%, P = 0.002). Pretreatment biopsies were unreliable to define the presence of SRC > 50% (sensitivity = 56.3%, positive predictive value = 43.9%). CONCLUSIONS: SRCs are aggressive neoplasms associated with poorer prognosis than other ADCs after primary esophagectomy. Because our data suggest that pretreatment biopsies failed to reliably define presence of SRC > 50%, presence of SRCs in pretreatment biopsies seems to be of no use to define treatment strategy or prognosis.

Background: Lung transplantations are highly complex procedures, often conducted in frail patients. Through the addition of immunosuppressants, healing can be compromised, primarily leading to the development of bronchopleural fistulas. Although esophageal fistulas (EFs) after lung transplantation remain rare, they are associated with significant morbidity. We aimed to investigate the clinical presentation, diagnostic approaches, and treatment strategies of EF after lung transplantation. Methods: All patients who developed EF after lung transplantation at the University Hospitals Leuven between January 2019 and March 2022 were retrospectively reviewed and the clinical presentations, diagnostic approaches, and treatment strategies were summarized. Results: Among 212 lung transplantation patients, 5 patients (2.4%) developed EF. Three patients were male and median age was 39 y (range, 34-63). Intraoperative circulatory support was required in 3 patients, with 2 needing continued support postoperatively. Bipolar energy devices were consistently used for mediastinal hemostasis. All EFs were right-sided. Median time to diagnosis was 28 d (range, 12-48) and 80% of EFs presented as recurrent respiratory infections or empyema. Diagnosis was made through computed tomography (nâ =â 3) or esophagogastroscopy (nâ =â 2). Surgical repair with muscle flap covering achieved an 80% success rate. All patients achieved complete resolution, with only 1 patient experiencing a fatal outcome during a complicated EF-related recovery. Conclusion: Although EF after lung transplantation remains rare, vigilance is crucial, particularly in cases of right-sided intrathoracic infection. Moreover, caution must be exercised when applying thermal energy in the mediastinal area to prevent EF development and mitigate the risk of major morbidity. Timely diagnosis and surgical intervention can yield favorable outcomes.
RESUMO
OBJECTIVES: Lung volume reduction surgery (LVRS) is an established therapeutic option for advanced emphysema. To improve patients' safety and reduce complications, an enhanced recovery protocol (ERP) was implemented. This study aims to describe and evaluate the short-term outcome of this ERP. METHODS: This retrospective single-centre study included all consecutive LVRS patients (1 January 2017 until 15 September 2020). An ERP for LVRS was implemented and stepwise optimised from 1 August 2019, it consisted of changes in pre-, peri- and postoperative care pathways. Patients were compared before and after implementation of ERP. Primary outcome was incidence of postoperative complications (Clavien-Dindo), and secondary outcomes included chest tube duration, incidence of prolonged air leak (PAL), length of stay (LOS) and 90-day mortality. Lung function and exercise capacity were evaluated at 3 and 6 months post-LVRS. RESULTS: Seventy-six LVRS patients were included (pre-ERP: n=41, ERP: n=35). The ERP cohort presented with lower incidence of postoperative complications (42% vs 83%, P=0.0002), shorter chest tube duration (4 vs 12 days, P<0.0001) with a lower incidence of PAL (21% vs 61%, P=0.0005) and shorter LOS (6 vs 14 days, P<0.0001). No in-hospital mortality occurred in the ERP cohort versus 4 pre-ERP. Postoperative forced expiratory volume in 1 s was higher in the ERP cohort compared to pre-ERP at 3 months (1.35 vs 1.02 l) and at 6 months (1.31 vs 1.01 l). CONCLUSIONS: Implementation of ERP as part of a comprehensive reconceptualisation towards LVRS, demonstrated fewer postoperative complications, including PAL, resulting in reduced LOS. Improved short-term functional outcomes were observed at 3 and 6 months.

Introduction: Compared with traditional static ice storage, controlled hypothermic storage (CHS) at 4-10°C may attenuate cold-induced lung injury between procurement and implantation. In this study, we describe the first European lung transplant (LTx) experience with a portable CHS device. Methods: A prospective observational study was conducted of all consecutively performed LTx following CHS (11 November 2022 and 31 January 2024) at two European high-volume centers. The LUNGguard device was used for CHS. The preservation details, total ischemic time, and early postoperative outcomes are described. The data are presented as median (range: minimum-maximum) values. Results: A total of 36 patients underwent LTx (i.e., 33 bilateral, 2 single LTx, and 1 lobar). The median age was 61 (15-68) years; 58% of the patients were male; 28% of the transplantations had high-urgency status; and 22% were indicated as donation after circulatory death. In 47% of the patients, extracorporeal membrane oxygenation (ECMO) was used for perioperative support. The indications for using the CHS device were overnight bridging (n = 26), remote procurement (n = 4), rescue allocation (n = 2), logistics (n = 2), feasibility (n = 1), and extended-criteria donor (n = 1). The CHS temperature was 6.5°C (3.7°C-9.3°C). The preservation times were 11 h 18 (2 h 42-17 h 9) and 13 h 40 (4 h 5-19 h 36) for the first and second implanted lungs, respectively, whereas the total ischemic times were 13 h 38 (4 h 51-19 h 44) and 15 h 41 (5 h 54-22 h 48), respectively. The primary graft dysfunction grade 3 (PGD3) incidence rates were 33.3% within 72 h and 2.8% at 72 h. Intensive care unit stay was 8 (4-62)â days, and the hospital stay was 28 (13-87)â days. At the last follow-up [139 (7-446)â days], three patients were still hospitalized. One patient died on postoperative day 7 due to ECMO failure. In-hospital Clavien-Dindo complications of 3b were observed in six (17%) patients, and 4a in seven (19%). Conclusion: CHS seems safe and feasible despite the high-risk recipient and donor profiles, as well as extended preservation times. PGD3 at 72â h was observed in 2.8% of the patients. This technology could postpone LTx to daytime working hours. Larger cohorts and longer-term outcomes are required to confirm these observations.
