As cardiothoracic surgeons, we face frequent challenges to our well-being and our ability to function as our best selves. Building personal resilience is an important way to help us manage these challenges. Here, the authors outline the scope of the problem, the consequences of burnout, and offer 4 strategies to train ourselves to be more resilient: (1) Pursuit of fulfillment, (2) Cultivation of community and belonging, (3) Mitigation of microstresses and avoiding feelings of overwhelm, and (4) Building a "resilience bank account.

Objectives: We aimed to evaluate how the current working climate of cardiothoracic surgery and burnout experienced by cardiothoracic surgeons influences their spouses and significant others (SOs).

Methods: A 33-question well-being survey was developed by the American Association for Thoracic Surgery Wellness Committee and distributed by e-mail to the SOs of cardiothoracic surgeons and to all surgeon registrants of the 2020 and 2021 American Association for Thoracic Surgery Annual Meetings with a request to share it with their SO. The 5-item Likert-scale survey questions were dichotomized, and associations were determined by χ or independent samples t tests, as appropriate.

The day-to-day life of a cardiothoracic surgeon and other high-stakes occupations is riddled with chronic stress punctuated by acute, sometimes life-threatening, crises. Additional stress from the realms of a surgeon's personal life can add to the silent burden surgeons often carry. The tolls paid for poor management of the cumulative stress load can impact surgeons and their patients, leading to errors of clinical judgment, burnout, early departures from practice, health issues, and substance abuse.

Objective: The primary aim of this trial was to assess the feasibility of minimally invasive esophagectomy (MIE) in a multi-institutional setting.

Background: Esophagectomy is an important, potentially curative treatment for localized esophageal cancer, but is a complex operation. MIE may decrease the morbidity and mortality of resection, and single-institution studies have demonstrated successful outcomes with MIE.

Background: Social disparities permeate non-small cell lung cancer (NSCLC) treatment, yet little is known about the effect of insurance status on the delivery of guideline surgical treatment for early-stage (I or II) NSCLC.

Methods: We used the California Cancer Registry (1996 through 2008) to identify patients 50 to 94 years old with early-stage NSCLC. We used logistic regression models to assess whether or not insurance status (private insurance, Medicare, Medicaid, no insurance, and unknown) had an effect on whether or not a lobectomy (or bilobectomy) is performed.

Background: Mediastinal staging in patients with non-small cell lung cancer (NSCLC) with endobronchial ultrasound-guided fine-needle aspiration (EBUS-FNA) requires a high negative predictive value (NPV) (ie, low false negative rate). We provide a conservative calculation of NPV that calls for caution in the interpretation of EBUS results.

Methods: We retrospectively analyzed our prospectively gathered database (January 2007 to November 2011) to include NSCLC patients who underwent EBUS-FNA for mediastinal staging.

The optimal operative management of giant paraesophageal hiatal hernias continues to evolve, with recent series reporting promising results with minimally invasive approaches. The laparoscopic repair of a giant paraesophageal hernia is one of the more challenging cases a minimally invasive surgeon may perform. Our technical approach to this procedure involves a consistent emphasis on several key operative points: circumferential sac dissection with maintenance of crural integrity; extensive mediastinal esophageal dissection; crural closure with pledgeted sutures; wedge Collis gastroplasty for shortened esophagus; 3-stitch fundoplication incorporating esophageal tissue with each bite; additional sutures securing the top of the fundoplication to the crura; and biologic mesh buttressing.

Background: Esophageal stents provide immediate palliation of malignant dysphagia; however, radiotherapy (RT) is a superior long-term option. We review the outcomes of combined esophageal stenting and RT for patients with malignant dysphagia.

Methods: We retrospectively reviewed patients with esophageal stents placed for palliation of malignant dysphagia from esophageal stricture, esophageal extrinsic compression, or malignant tracheoesophageal fistula (TEF).

We present the current optimal uses and limitations of positron emission tomography/computed tomography (PET/CT) as it relates to the diagnosis and staging of non-small cell lung cancer (NSCLC). PET/CT demonstrates increased accuracy in the workup of solitary pulmonary nodules for malignancy compared with CT alone, and we discuss its benefits and limitations. We review pitfalls in measured standardized uptake values of lung lesions caused by respiratory artifacts, the lower sensitivity for detection of small lung nodules on non-breath-hold CT, and the benefits of obtaining an additional diagnostic CT for the maximum sensitivity of lung nodule detection.
