Objective: This study evaluated the surgical and long-term patient-reported quality of life outcomes of patients undergoing esophagectomy with gastric advancement. Methods: A retrospective review was performed of all patients undergoing esophagectomy with gastric advancement from 2005 to 2016. Quality of life outcomes were evaluated using the European Organization for research and treatment of cancer quality of life questionnaire - esophageal cancer module (QLQ-OES18), which covered 10 symptom scales: dysphagia, trouble swallowing saliva, choking when swallowing, eating, dry mouth, trouble with taste, trouble with coughing, trouble speaking, reflux, and pain. Results: A total of 129 patients were followed up to 16 years (791.3 patient-years). The median age was 63.5 (IQR 55.9-69.3) years, and 79.9% were male. Eighty-six percentage (111/129) of patients had esophageal malignancy as their operative indication. Median survival was 7.1 years, with patients with benign disease experiencing longer postoperative survival ( P = .006). The response rate to QLQ-OES18 surveys was 53.7% (22/41; median follow-up: 10.4 years). Patients who experienced early postoperative complications were more likely to report trouble with coughing ( P = .032) than those who did not experience early complications. However, postoperative leaks were not associated with worsened QOL. Of note, age ≥ 65 years, obesity status, surgical indication, location of the primary esophageal lesion, tumor stage, and the occurrence of delayed postoperative complications were not associated with long-term QOL (all P > .05). Conclusion: Patients undergoing esophagectomy with gastric advancement generally had good quality of life 10 years postoperatively, though early postoperative complications and gender appeared to influence symptom burden. These findings may improve pre and postoperative patient counseling.

Background. Retained hemothorax (RH) is a common problem in cardiothoracic and trauma surgery. We aimed to determine the optimum agitation technique to enhance thrombus dissolution and drainage and to apply the technique to a porcine-retained hemothorax. Methods. Three agitation techniques were tested: flush irrigation, ultrasound, and vibration. We used the techniques in a benchtop model with tissue plasminogen activator (tPA) and pig hemothorax with tPA. We used the most promising technique vibration in a pig hemothorax without tPA. Statistics. We used 2-sample t tests for each comparison and Cohen d tests to calculate effect size (ES). Results. In the benchtop model, mean drainages in the agitation group and control group and the ES were flush irrigation, 42%, 28%, and 2.91 ( P = .10); ultrasound, 35%, 27%, and .76 ( P = .30); and vibration, 28%, 19%, and 1.14 ( P = .04). In the pig hemothorax with tPA, mean drainages and the ES of each agitation technique compared with control (58%) were flush irrigation, 80% and 1.14 ( P = .37); ultrasound, 80% and 2.11 ( P = .17); and vibration, 95% and 3.98 ( P = .06). In the pig hemothorax model without tPA, mean drainages of the vibration technique and control group were 50% and 43% (ES = .29; P = .65). Discussion. In vitro studies suggested flush irrigation had the greatest effect, whereas only vibration was significantly different vs the respective controls. In vivo with tPA, vibration showed promising but not statistically significant results. Results of in vivo experiments without tPA were negative. Conclusion. Agitation techniques, in combination with tPA, may enhance drainage of hemothorax.

AbstractBackgroundA relative contraindication for lung transplant (LT) is coronary disease burden sufficient to cause risk of myocardial infarction after LT. We analyzed cause of death and outcomes of our LT patients with coronary artery disease (CAD).MethodsInpatient records from March 1, 2004, to January 31, 2015, were retrospectively examined and data of 306 LTs extracted. Twenty‐five patients without coronary angiography (CA) and 7 with redo LTs were excluded. The other 274 patients were divided into 2 groups: CAD (n = 116) and no CAD (n = 158). Patients with prior revascularization or coronary stenosis >10% were placed into the CAD group.ResultsThe CAD group was older and had more male patients, greater history of smoking and hypertension, and greater proportion of patients with interstitial lung disease than the no‐CAD group. CAD patients were more likely to receive a single‐lung transplant. Death of cardiac causes occurred for 2 patients (1.7%) in the CAD group and for 1 patient (0.6%) in the no‐CAD group (P = 0.39).ConclusionsThis analysis shows that compared with patients who have no CAD, patients with CAD have different demographic characteristics and receive more single‐lung transplants. Incidence of death of cardiac causes is rare.
