RESUMO
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.
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.

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
Background: Extracorporeal life support (ECLS) is not routinely used at our center during sequential single-lung transplantation (LTx), but is restricted to anticipate and overcome hemodynamic and respiratory problems occurring peri-operatively. In this retrospective descriptive cohort study, we aim to describe our single-center experience with ECLS in LTx, analyzing ECLS-related complications. Methods: All transplantations with peri-operative ECLS use [2010-2020] were retrospectively analyzed. Multi-organ and heart-lung transplantation were excluded. Demographics, support type and indications are described. Complications are categorized according to the underlying nature and type. Data are presented as median [interquartile range (IQR)]. Kaplan-Meier was used for survival analysis. Results: The overall use of ECLS was 22% (156/703 patients) with a mean age of 52 years (IQR, 36-59 years). Transplant indications in ECLS cohort were interstitial lung disease (38%; n=60), chronic obstructive pulmonary disease (COPD) (19%; n=29), cystic fibrosis (17%; n=26) and others (26%; n=41). Per indication, 94% (15/16) of pulmonary arterial hypertension patients required ECLS, whereas only 8% (29/382) of COPD patients did. In 16% (25/156) of supported patients, veno-venous extracorporeal membrane oxygenation was initiated, while 77% (120/156) required veno-arterial support, and 7% (11/156) cardiopulmonary bypass. Thirty-day mortality was 6% (9/156). Sixteen percent (25/156) of patients were bridged to transplantation on ECLS and 24% (37/156) required post-operative support. Main reasons to use ECLS were intra-operative hemodynamic instability (53%; n=82), ventilation/oxygenation problems (22%; n=34) and reperfusion edema (17%; n=26). Overall incidence of patients with at least one ECLS-related complication was 67% (n=104). Most common complications were hemothorax (25%; n=39), need for continuous renal replacement therapy (19%; n=30), and thromboembolism (14%; n=22). Conclusions: ECLS was required in 22% of LTxs, with a reported ECLS-related complication rate of 67%, of which the most common was hemothorax. Larger databases are needed to further analyze complications and develop tailored deployment strategies for ECLS-use in LTx.
RESUMO
Background: Lung re-transplantation (re-LTx) is the only therapeutic option for selected patients with advanced allograft dysfunction. This study aims to describe our center's experience to illustrate the feasibility and safety of off-pump re-LTx avoiding clamshell incision. Methods: We performed a retrospective analysis of 42 patients who underwent bilateral re-LTx between 2007 and 2021. Patients were classified according to their surgical approach and extracorporeal life support (ECLS)-use. Demographics, surgical technique, and short- and long-term outcomes were compared between groups. Continuous data were examined with an independent-sample t-test or non-parametric test. Pearson's chi-squared and Fisher's exact were used to analyze categorical data. Results: Twenty-six patients (61.9%) underwent re-LTx by anterior thoracotomy without ECLS. Compared to the more invasive approach (thoracotomy with ECLS and clamshell with/without ECLS, n=16, 38.1%), clamshell-avoiding off-pump re-LTx patients had a shorter operative time (471.6±111.2 vs. 704.0±273.4 min, P=0.010) and less frequent grade 3 primary graft dysfunction (PGD-3) at 72 h (7.7% vs. 37.5%, P=0.038). No significant difference was found in PGD-3 incidence within 72 h, mechanical ventilation, intensive care unit (ICU) and hospital stay, and the incidence of reoperation within 90 days between groups (P>0.05). In the long-term, the clamshell-avoiding and off-pump approach resulted in similar 1- and 5-year patient survival vs. the more invasive approach. Conclusions: Our experience shows that clamshell-avoiding off-pump re-LTx is feasible and safe in selected patients on a case-by-case evaluation.
RESUMO
Pectus carinatum is characterized by a protruding sternum. This deformity can be surgically corrected through the minimally invasive Abramson technique. In this procedure, a presternal metal correctional bar, secured to rib-attached stabilizers, is implanted to redress the sternum to a neutral position. To anticipate the intended position of the sternum, manual compression is applied over the sternal deformity. We describe a modified version of the Abramson procedure, encompassing a table-mounted PectusAssist™ System which generates a constant mechanical compression over the protruding sternum. The PectusAssist™ System, most importantly, eliminates the necessity of manually applying repetitive pressure on the deformity, and therefore maintains a more stable sternal position. This will ensure accuracy of the template used to bend the bar into its desired configuration. The modification we propose also simplifies presternal tunnel creation as the two bilateral retromuscular tunnels, that need to be connected presternally, are potentially better aligned due to a more stable and reduced position of the sternum. The PectusAssist™ System makes the procedure less labor intensive and reduces variability without interfering with the safety of the procedure. Therefore, we advise standard use of the PectusAssist™ System during minimally invasive repair of pectus carinatum by the Abramson procedure.
RESUMO
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.

BACKGROUND: The current gold standard for treatment of locally advanced esophageal adenocarcinoma is neoadjuvant chemotherapy or chemoradiotherapy followed by surgery. The shift toward neoadjuvant chemoradiotherapy (nCRT) was driven by the Chemoradiotherapy for Oesophageal Cancer Followed by Surgery Study (CROSS) trial. This study reassessed, in daily practice, the presumed advantage of nCRT followed by surgery on long-term survival compared with primary surgery, in a group of all adenocarcinomas treated through a transthoracic approach with extensive 2-field lymphadenectomy. METHODS: This retrospective cohort study with propensity score-matched analysis included all surgically treated patients between 2000 and 2018 with locally advanced adenocarcinoma (cT1/2 N+ or cT3/4 N0/+). For appropriate comparison, exclusion criteria of the CROSS trial were applied. Patients were matched on age, Charlson comorbidity score, clinical tumor length, and lymph node status. The primary end point was 5-year overall survival. RESULTS: There were 473 eligible patients who underwent primary surgery (225 patients) or nCRT + surgery (248 patients). After propensity score-matched analysis, 149 matched cases were defined in each group for analysis. There was no significant difference after 5 years between the matched groups in median overall survival (32.5 and 35.0 months, P = .41) and median disease-free survival (14.3 and 13.5 months, P = .16). nCRT was associated with significantly more postoperative complications (mean Comprehensive Complication Index score: 21.0 vs 30.5, P < .0001) and longer mean stay in the hospital (14.0 vs 18.2 days, P = .05) and intensive care unit (11.7 vs 37.7 days, P = .05). CONCLUSIONS: Our propensity score-matched results indicate that primary surgery, performed through transthoracic approach with extensive 2-field lymphadenectomy, can offer a comparable overall and disease-free survival after 5 years, with potentially fewer postoperative complications and shorter hospital and intensive care unit stay compared with nCRT followed by surgery.

BACKGROUND: Brain metastases after esophagectomy are rare. Moreover, a diagnostic uncertainty remains as pathology is rarely obtained and radiological features can show similarities to primary brain tumors. Our aim was to demonstrate the diagnostic uncertainty and identify risk factors associated with brain tumors (BT) after esophagectomy with curative intent. METHODS: All patients who underwent an esophagectomy with curative intent from 2000 to 2019 were reviewed. Diagnostics and characteristics of BT were analyzed. Multivariable logistic and cox regression were performed to determine factors associated with development of BT and survival, respectively. RESULTS: In total, 2131 patients underwent esophagectomy with curative intent, of which 72 patients (3.4%) developed BT. Pathological diagnosis was obtained in 26 patients (1.2%), of which 2 patients were diagnosed with glioblastoma. On multivariate analysis, radiotherapy (OR, 7.71; 95%CI: 2.66-22.34, p < 0.001) was associated with an increased risk of BT and early-stage tumors (OR, 0.29; 95%CI: 0.10-0.90, p = 0.004) with a decreased risk of BT. Median overall survival was 7.4 months (95%CI: 4.80-9.96). BT treated with curative intent (surgery or stereotactic radiation) had a significantly better median overall survival (16 months; 95%CI: 11.3-20.7) compared to those without (3.7 months; 95%CI: 0.9-6.6, p < 0.001) CONCLUSIONS: Advanced stage tumors and radiotherapy seem related to the development of brain tumors after esophagectomy with curative intent. However, an important diagnostic uncertainty remains in these patients as pathological diagnosis is only obtained in a minority of cases. Tissue confirmation can be useful to inform a patient-tailored multimodality treatment strategy in select patient.

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).

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: 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: 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.

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: Organ transplantation is hampered by shortage of suitable organs. In countries with a legal framework, organ donation following euthanasia is an option labeled "donation after cardio-circulatory death category V" (DCD-V). We describe our experience with lung transplantation (LTx) after euthanasia and evaluate post-transplant outcome using a matched comparison to DCD-III (withdrawal from life-sustaining therapy) and donation after brain death (DBD). METHODS: All bilateral LTx between 2007 and 2020 were retrospectively analyzed. Matching was performed for recipient age and gender, indication for LTx, mean pulmonary artery pressure, extracorporeal life support, and donor age, which resulted in 1:2 DCD-III and 1:3 DBD matching. Primary graft dysfunction (PGD), chronic lung allograft dysfunction (CLAD), and patient survival were analyzed. RESULTS: A total of 769 LTx were performed of which 22 from DCD-V donors (2.9%). Thirteen women and 9 men expressed their wish to become organ donor after euthanasia. Euthanasia request was granted for irremediable neuromuscular (N = 9) or psychiatric (N = 8) disorder or unbearable and unrecoverable pain (N = 5). PGD (grade 3, within 72 hours post-transplant) was 23.8% in the DCD-V cohort, which is comparable to DCD-III (27.9%; p = 1.00) and DBD (32.3%; p = .59). CLAD-free 3- and 5-year survival were 86.4% and 62.8%, respectively, and comparable to DCD-III (74.4% and 60.0%; p = .62) and DBD (72.6% and 55.5%; p = .32). Five-year patient survival was 90.9%, not significantly different from both DCD-III (86.0%; p = 1.00) and DBD (78.1%; p = .36). CONCLUSIONS: We observed that LTx with DCD-V allografts is feasible and safe, yielding no evidence for differences in short- and long-term outcome compared to matched cohorts of DCD-III and DBD.

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.

BACKGROUND: The aim of this review is to provide an overview of the outcomes after minimally invasive pectus cartinatum repair (MIRPC) by the Abramson method to determine its effectiveness. METHODS: The PubMed and Embase databases were systematically searched. Data concerning subjective postoperative esthetic outcomes after initial surgery and bar removal were extracted. In addition, data on recurrence, complications, operative times, blood loss, post-operative pain, length of hospital stay, planned time to bar removal and reasons for early bar removal were extracted. The postoperative esthetic result, was selected as primary outcome since the primary indication for repair in pectus carinatum is of cosmetic nature. RESULTS: Six cohort studies were included based on eligibility criteria, enrolling a total of 396 patients. Qualitative synthesis showed excellent to satisfactory esthetic results in nearly all patients after correctional bar placement (99.5%, n = 183/184). A high satisfaction rate of 91.0% (n = 190/209) was found in patients after bar removal. Recurrence rates were low with an incidence of 3.0% (n = 5/168). The cumulative postoperative complication rate was 26.5% (n = 105/396), of whom 25% required surgical re-intervention. There were no cases of mortality. CONCLUSIONS: Minimally invasive repair of pectus carinatum through the Abramson method is effective and safe. Its efficacy is demonstrated by the excellent to satisfactory esthetic results in 99.5% and 91.0% of patients after respectively correctional bar placement and implant removal. Future studies should aim to compare different treatment options for pectus carinatum in order to elucidate the approach of choice for different patient groups.

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.

BACKGROUND/PURPOSE: Among patients suspected of pectus excavatum, visual examination is a key aspect of diagnosis and, moreover, guides work-up and treatment strategy. This study evaluated the inter-observer and intra-observer agreement of visual examination and diagnosis of pectus excavatum among experts. METHODS: Three-dimensional surface images of consecutive patients suspected of pectus excavatum were reviewed in a multi-center setting. Interactive three-dimensional images were evaluated for the presence of pectus excavatum, asymmetry, flaring, depth of deformity, cranial onset, overall severity and morphological subtype through a questionnaire. Observers were blinded to all clinical patient information, completing the questionnaire twice per subject. Agreement was analyzed by kappa statistics. RESULTS: Fifty-eight subjects with a median age of 15.5 years (interquartile range: 14.1-18.2) were evaluated by 5 (cardio)thoracic surgeons. Pectus excavatum was visually diagnosed in 55% to 95% of cases by different surgeons, revealing considerable inter-observer differences (kappa: 0.50; 95%-confidence interval [CI]: 0.41-0.58). All other items demonstrated inter-observer kappa's of 0.25-0.37. Intra-observer analyses evaluating the presence of pectus excavatum demonstrated a kappa of 0.81 (95%-CI: 0.72-0.91), while all other items showed intra-observer kappa's of 0.36-0.68. CONCLUSIONS: Visual examination and diagnosis of pectus excavatum yields considerable inter-observer and intra-observer disagreements. As this variation in judgement could impact work-up and treatment strategy, objective standardization is urged. LEVELS OF EVIDENCE: III.
