Summary Introduction Peroral plication of the esophagus (POPE) can reduce sump size and improve symptoms in end-stage achalasia. However, its long-term efficacy and safety are unknown. Methods Patients with end-stage achalasia who underwent POPE at our institution (2016–2024) were identified. Data were abstracted for patient demographics, procedural details, and clinical and radiographic outcomes. Results Twelve patients underwent POPE. The technical success rate was 100%, with mean procedural time of 57 minutes and without adverse events. Symptomatic improvement occurred in 75% of patients (mean follow-up of 15 months), while 86% had radiographic improvement in sump size. Repeat POPE in 6 (50%) patients a mean of 2.6 years after index POPE and a third POPE in four (33%) patients a mean of 3.1 years later was performed, with similar technical success rates and outcomes to the index POPE. Conclusions POPE is a safe and repeatable long-term therapeutic option in end-stage achalasia.

Abstract OBJECTIVES To estimate gender disparities among first and last authorships in cardiothoracic randomized controlled trials (RCTs) and association of gender with publications in high-impact journals. METHODS PubMed/MEDLINE database was searched from 1 January 2014 to 31 December 2020 using R statistical software via the ‘easyPubMed’ package to retrieve pertinent data. The ‘gender’ package was utilized to determine gender using the United States Social Security Administration Baby Name Data. The percentage of female first and last authors were computed along with determining the uniqueness of the names. The association of gender and publication in high-impact peer-reviewed journals was delineated. Jonckheere’s trend was computed. RESULTS The database search retrieved a total of 4820 RCTs, of which gender was encoded for the first author in 3247 (67%) RCTs, among which 911 (28%) studies had women as first authors, with a similar trend across 7 years (P = 0.23). Gender was encoded for the last author of 3204 (66%) RCTs, of which 622 (19%) studies had women as last authors, with a similar trend across 7 years (P = 0.45). A total of 627 studies were published in high-impact-factor journals, among which 79 (16%) studies had female first authors and 67 (13%) studies had female last authors. CONCLUSIONS There is an obvious gender disparity of first and last authors in cardiothoracic surgery-related RCTs, with a similar trend across 7 years. However, the post-hoc analysis did demonstrate a positive trend with an increase in the number of female first authors, demonstrating progress.

Summary: The latissimus dorsi muscle is the workhorse flap for intrathoracic reconstruction. Prior thoracotomy, which divides the latissimus dorsi muscle, limits the muscle’s intrathoracic reach. We present our experience using the distal portion of the muscle for intrathoracic reconstruction based off an intercostal vessel. We also demonstrate the ability of this intercostal perforator to allow for chimeric flap elevation with a separate skin paddle, depending on the branching pattern of the intercostal vessels. This study provides a case series of three consecutive patients, treated between September 2021 and June 2022. The intrathoracic pathology addressed in these patients are bronchopleural fistula, aortoesophageal fistula, and bronchoesophageal fistula. All patients had the resolution of symptoms related to intrathoracic fistulae and did not experience recurrence. This novel pedicled muscle flap can be an additional option for patients with prior thoracotomy and avoids the morbidity which can be seen with the serratus or rectus abdominis muscle flaps.

Every effort must be made by the leaders in our field, as well as by every individual cardiothoracic surgeon, to assure equal opportunity for all cardiothoracic surgeons, regardless of race, gender or any other sociodemographic source of bias. Every effort must be made by every surgeon, not just those in particular leadership roles. Opportunities for advancement must be equal in multiple domains, including clinical practice, patient referral, clinical leadership, academic leadership, institutional leadership and leadership in professional medical and surgical societies. Such actions to minimize bias and promote inclusivity will also ensure that cardiothoracic surgical care is provided by a workforce that represents the diversity of patients whom we serve. In the final analysis, it is an absolute fact that gender differences in payments to cardiothoracic surgeons are absolutely unacceptable and cannot be tolerated.

Abstract Purpose: This phase Ib/2 trial investigated pembrolizumab-containing trimodality therapy in patients with gastroesophageal junction (GEJ) adenocarcinoma. Patients and Methods: Patients with GEJ adenocarcinoma (cT1–3NanyM0) received neoadjuvant pembrolizumab-containing chemoradiation (CROSS regimen) followed by surgical resection and adjuvant pembrolizumab. The primary endpoints were tolerability in the first 16 patients and pathologic complete response [pCR (ypT0N0)]. Secondary endpoints included progression-free survival (PFS) and overall survival (OS). An independent propensity-score-matched cohort (treated with CROSS without immunotherapy) was used for comparison. Exploratory analyses included immune biomarkers in the tumor microenvironment (TME) and plasma. Results: We enrolled 31 eligible patients, of whom 29 received all expected doses of neoadjuvant pembrolizumab and 28 underwent R0 resection. Safety endpoints were met. The primary efficacy endpoint was not met [7/31 (22.6%) achieved pCR]. Patients with high [i.e., combined positive score (CPS) ≥ 10] baseline expression of programmed death (PD)-L1 in the TME had a significantly higher pCR rate than those with low expression [50.0% (4/8) vs. 13.6% (3/22); P = 0.046]. Patients with high PD-L1 expression also experienced longer PFS and OS than propensity-score-matched patients. Among trial patients with PD-L1 CPS < 10, unprespecified analysis explored whether extracellular vesicles (EV) could identify further responders: an elevated plasma level of PD-L1–expressing EVs was significantly associated with higher pCR. Conclusions: Adding pembrolizumab to trimodality therapy showed acceptable tolerability but did not meet the pre-specified pCR endpoint. Exploratory analyses suggested that high PD-L1 expression in the TME and/or on EVs may identify patients most likely to achieve tumor response.

Device infection is a major potential complication following ventricular assist device implantation and can lead to devastating consequences. The treatment options are few and often challenging to implement. The most durable option may require device exchange to obtain adequate source control. Due to the prolonged support times offered by the new left ventricular assist devices (LVADs), there is concern that the number of patients that will eventually require repeated device exchanges for device infection will increase. The benefit of medical antibiotic therapy alone is limited and is frequently unsuccessful. Surgical treatment strategies that improve outcomes by eliminating the infection and by preventing infection recurrence are needed. We report a case of a third-time LVAD exchange (4th device implant) for device infection within eight years of the index implant, and we briefly discuss the role of the greater omentum in the surgical treatment of this complication.

e18634 Background: Informed patients have better health outcomes. In a study of 1,057 patient encounters with 3,552 clinical decisions, only 9% resulted in informed medical decisions.The complexity of treatments and patients' limitations in health literacy (especially common in underserved communities) make it difficult for patients to engage in SDM. In 2017, A Breath of Hope Lung Foundation introduced An Animated Patient’s Guide to Lung Cancer (APG), an online resource aimed at improving patient knowledge. Methods: APG consists of animations, expert FAQ videos, slide shows, infographics, patient-experience videos, knowledge-assessment tools, and learner feedback. Video views, duration of use, and learner responses to multiple-choice questions on the APG website were collected for 33 months – through August 2020. Total APG views, most frequently viewed animations and expert videos were monitored on the website and on YouTube, to measure learner responses to outcome-based questions, and learner intent-to-implement changes. Results: 212,336 total views: 142,998 unique visitors: 59% from U.S. and 41% from 50 other countries. Unique U.S. visitors: 43,872 patients, 16,030 caregivers, and 7,593 health providers. 94% reported they will ‘use new information to better self-manage their lung cancer’ (n = 277); 98% ‘will discuss information learned with their doctor’ (n = 455), and 93% ‘plan to discuss treatment options with their doctor’ (n = 272). Conclusions: Multimedia ‘animated’ formats of learning tailored to the needs and learning styles of lung cancer patients provides effective learning, informed patients, increased management skills, and improved engagement in shared decision making.

239 Background: After trastuzumab (T) approval for advanced HER2-positive E/GEJ-AC, HER2 testing has increased in patients (pts) with resectable disease. Neoadjuvant carboplatin/paclitaxel chemoradiation (nCP-CRT) is a common therapy approach. We performed the largest evaluation, to our knowledge, of the prognostic impact of HER2 in E/GEJ-AC pts treated with nCP-CRT. Methods: We retrospectively reviewed medical records of all trimodality-eligible (T2+ or N+) pts with E/GEJ-AC who started nCP-CRT (usually 50.4 Gy) with planned surgery at Mayo Clinic (2014-2019). HER2 was tested using standard criteria for HER2 positivity (ie, immunohistochemistry 3+ or amplification by in situ hybridization). Clinicopathologic data and time to recurrence (TTR), disease free survival (DFS), overall survival (OS), survival after recurrence (SAR), and pathologic complete response (pCR – ie, no residual tumor in primary or nodes) were collected. Kaplan Meier and multivariate Cox analysis were used. Results: Of 161 consecutive eligible pts, HER2 status was available in 107 pts (HER2-positive n=26, HER2-negative n=81) of whom n=82 had surgery and n=19 had pCR. Most tumors were clinical T3 (80%) or N+ (81%), histologic grade 3 of 3 (62%). HER2 positivity was significantly associated with lower grade, but not with age, clinical T or N, or ECOG performance status (PS). A similar proportion of HER2-positive ( vs negative) pts had surgery. Among pts who had surgery, pCR rates were lower in HER2-positive ( vs negative) pts (11% [2/19] vs 27% [17/63]). After a median follow up of 23 mo, DFS and TTR were significantly shorter in HER2 positive ( vs negative) pts, independent of other pretreatment covariables (Table). Yet OS was comparable. Lung recurrence was enriched in HER2 positive ( vs negative) pts. Among pts with recurrence, SAR was longer in HER2-positive vs -negative pts. A total of 53% (10/19) of previously HER2-positive pts received T-based therapy after recurrence, and these pts were the drivers of favorable SAR (median 22 mo in n=10 HER2-positive pts who received T vs 11 mo in n=9 HER2-positive pts who did not receive T vs 11 mo in n=40 HER2-negative pts; P log-rank=.01). Conclusions: HER2 positivity ( vs negativity) is independently associated with shorter TTR and DFS, but more comparable OS. The adverse association of HER2 on tumor response and TTR may have been largely overcome through enhanced survival after recurrence, although OS data are maturing. These data may have implications for the design of endpoints in future curative-intent anti-HER2 trials. [Table: see text]

There are limited data regarding the surgical management of primary pulmonary artery sarcomas (PPAS) because of their rarity and complicated diagnostic history. The objective of this study was to analyze our institution’s long-term surgical management outcomes for PPAS in the absence of a care pathway. From May 1997 to June 2013, 8 patients (mean age 60.6 ± 11.8 years; range, 40-73 years; 5 women and 3 men) underwent surgical intervention for PPAS at our institution. The most common computed tomography finding was a luminal filling defect obstructing the pulmonary artery (PA), without evidence of extraluminal extension. Three patients underwent debulking/pulmonary endarterectomy alone and 5 patients underwent a more radical resection with PA patch angioplasty, PA resection and reconstruction, pulmonary valve replacement, and unilateral pneumonectomy. The mean postoperative survival in this series was 3.8 ± 3.6 years (range, 1-11.9 years), with 2 radical surgical resection patients alive at 4.9 and 11.9 years, respectively. For those patients with incomplete resection, 3-dimensional (3D) models were created to demonstrate the advantage of a preoperative guide for a more complete resection and what it would entail. Six patients had local recurrences with mean disease-free interval of 14 ± 10.9 months (range, 2 months-2.5 years), and 2 patients with re-resections had an overall postoperative survival of 2.8 and 11.9 years, respectively. In our small cohort of PPAS, patients treated with radical surgical resection had better survival. The small number of PPAS cases in this series makes proving this association unlikely but warrants consideration.
