Abstract
INTRODUCTION The standard technique for Ivor Lewis minimally invasive esophagectomy involves a two-stage approach necessitating repositioning mid-procedure. TECHNIQUE We describe our technique for a one-stage hand-assisted minimally invasive esophagectomy that allows sequential access to the chest and abdomen within the same surgical field, eliminating the need for repositioning. The patient is positioned in a "corkscrew" configuration with the abdomen supine and the chest rotated to the left to allow access to the right chest. The abdomen and chest are prepped into a single operative field. This technique allows sequential access to the abdomen for gastric mobilization, chest for division of the esophagus, abdomen for construction of the gastric conduit, and chest for intrathoracic anastomosis. CONCLUSION This approach enables extracorporeal construction of the conduit, which helps ensure a clear distal margin on the specimen and facilitates conduit length by placing the stomach on stretch during stapling.

Abstract
BACKGROUND Esophagectomy is a complex operation in which outcomes are profoundly influenced by operative experience and volume. We report the effects of experience and innovation on outcomes in minimally invasive esophagectomy. METHODS Esophageal resections for cancer from 2007 to 2016 at Levine Cancer Institute at Carolinas Medical Center (Charlotte, NC) were reviewed. During this time, three changes in technique were made to improve outcomes: vascular evaluation of the gastric conduit to improve anastomotic healing (beginning at case #63), one-stage approach to permit access to abdomen and chest through one draped surgical field (case #82), and adoption of a lung-protective anesthetic protocol (case #101). Mortality, operative time, complications, and length of stay were analyzed relative to these interventions using GLM regression. RESULTS 200 patients underwent minimally invasive esophagectomy. There were no mortalities at 30 days, and no change in mortality rate at 60 and 90 days. Anastomotic leak decreased significantly after the introduction of intraoperative vascular evaluation of the gastric conduit (3.6 vs 19.4%). Operative time decreased with adoption of a one-stage approach (416 vs 536 min). Pulmonary complications decreased coincident with a change in anesthetic technique (pneumonia 6 vs 28%). Lymph node harvest increased over time. Length of stay was driven primarily by complications and decreased with operative experience. CONCLUSIONS Postoperative complications, operative time, and length of stay decreased with case experience and alterations in surgical and anesthetic technique. We believe that adoption of the techniques and technology described herein can reduce complications, reduce hospital stay, and improve patient outcomes.

Abstract
BACKGROUND Anastomotic leak following esophagectomy is associated with significant morbidity and mortality. As hospital length of stay decreases, the timely diagnosis of leak becomes more important. We evaluated CT esophagram, white blood count (WBC), and drain amylase levels in the early detection of anastomotic leak. METHODS The diagnostic performance of CT esophagram, drain amylase >800 IU/L, and WBC >12,000/µL within the first 10 days after surgery in predicting leak at any time after esophagectomy was calculated. RESULTS Anastomotic leak occurred in 13 patients (13%). CT esophagram performed within 10 days of surgery diagnosed six of these leaks with a sensitivity of 0.54. Elevation in drain amylase level within 10 days of surgery diagnosed anastomotic leak with a sensitivity of 0.38. When the CT esophagram and drain amylase were combined, the sensitivity rose to 0.69 with a specificity of 0.98. WBC elevation had a sensitivity of 0.92, with a specificity of 0.34. Among 30 patients with normal drain amylase and a normal WBC, one developed an anastomotic leak. CONCLUSIONS Drain amylase adds to the sensitivity of CT esophagram in the early detection of anastomotic leak. Selected patients with normal drain amylase levels and normal WBC may be able to safely forgo CT esophagram.

Abstract
We report our initial experience with minimally-invasive esophagectomy in 32 patients at Carolinas Medical Center, a community academic medical center. Indications for surgery were adenocarcinoma in 27, squamous cell carcinoma in 3, and benign stricture in 2. Transthoracic Ivor-Lewis esophagectomy with laparoscopy and thoracoscopy was performed in 28, a 3-stage esophagectomy in 3, and transhaital esophagectomy in 1. There was no operative mortality and median hospital stay was 10.5 days for patients treated with minimally invasive esophagectomy. This compares with an operative mortality of 8.9% and median hospital stay of 17 days for open esophagectomy in our institution.

Abstract
With the general increase in human lifespan, cardiac surgeons are faced with treating an increasing number of elderly patients. The aim of our study was to investigate whether advanced age poses an increased risk for major morbidity and mortality with repair of acute type A aortic dissection. Between 2000 and 2008, 119 patients underwent emergency operation for acute type A aortic dissection at two institutions; 90 were younger than 70 years of age and 29 patients were 70 years or older. Major morbidity, operative and 5-year actuarial survival were compared between groups. The operative mortality rates were comparable between the two groups (18.9% in patients <70 years vs. 24.1% for patients >or=70 years, P=0.6). There was no difference in the rates of reoperation for bleeding (<70 years 31.7% vs. 14.3% for >or=70 years, P=0.09), stroke (18.9% for those <70 years vs. 20.7% for those >or=70 years, P=0.79), acute renal failure (22.2% for those <70 years vs. 17.2% for those >or=70 years, P=0.79) or prolonged ventilation (34.4% for those <70 years vs. 24.1% for those >or=70 years, P=0.36) between the two groups. Actuarial 5-year survival rates were 77% for patients <70 years vs. 59% for patients >or=70 years (P=0.07). The mortality for patients who presented with hemodynamic instability was markedly higher (10 out of 14 patients, 71.4%) compared with the mortality of those who presented with stable hemodynamics (21 out of 88 patients, 23.9%, P<0.001), regardless of age group. No significant differences in operative mortality, major morbidity and actuarial 5-year survival were observed between patients >or=70 years and younger patients although there was a trend toward a lower actuarial 5-year survival in older patients. Surgery for type A acute aortic dissection in patients 70 years or older can be performed with acceptable outcomes. Hemodynamic instability portends a poor prognosis, regardless of age.

Aprotinin in cardiac surgery patients: is the risk worth the benefit? Eur J Cardiothorac Surg 2009; 36:869-75. [PMID: 19782574 DOI: 10.1016/j.ejcts.2009.04.053] [Citation(s) in RCA: 19] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2008] [Revised: 04/07/2009] [Accepted: 04/09/2009] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Aprotinin is the only Food and Drug Administration-approved agent to reduce haemorrhage related to cardiac surgery and its safety and efficacy has been extensively studied. Our study sought to compare the efficacy, early and late mortality and major morbidity associated with aprotinin compared with e-aminocaproic acid (EACA) in cardiac surgery operations. METHODS Between January 2002 and December 2006, 2101 patients underwent coronary artery bypass grafting (CABG), valve surgery or CABG and valve surgery in our institution with the use of aprotinin (1898 patients) or EACA (203 patients). Logistic regression and propensity score analysis were used to adjust for imbalances in the patients' preoperative characteristics. The propensity score-adjusted sample included 570 patients who received aprotinin and 114 who received EACA (1-5 matching). RESULTS Operative mortality was higher in the aprotinin group in univariate (aprotinin 4.3% vs EACA 1%, p=0.023) but not propensity score-adjusted multivariate analysis (4% vs 0.9%, p=0.16). In propensity score-adjusted analysis, aprotinin was also associated with a lower rate of blood transfusion (38.8% vs 50%, p=0.04), a lower rate of haemorrhage-related re-exploration (3.7% vs 7.9%, p=0.04) and a higher risk of in-hospital cardiac arrest (3.7% vs 0%, p=0.03) and a marginally but not statistically significantly higher risk of acute renal failure (6.8% vs 2.6%, p=0.09). In Cox proportional hazards regression analysis, the risk of late death was higher in the aprotinin compared to EACA group (hazard ratio=4.33, 95% confidence interval (CI)=1.60-11.67, p=0.004). CONCLUSION Aprotinin decreases the rate of postoperative blood transfusion and haemorrhage-related re-exploration, but increases the risk of in-hospital cardiac arrest and late mortality after cardiac surgery when compared to EACA. Cumulative evidence suggests that the risk associated with aprotinin may not be worth the haemostatic benefit.

Can timing of tracheal extubation predict improved outcomes after cardiac surgery? HSR PROCEEDINGS IN INTENSIVE CARE & CARDIOVASCULAR ANESTHESIA 2009; 1:39-47.

Abstract
INTRODUCTION Early tracheal extubation is a common goal after cardiac surgery. Our study aims to examine whether timing of tracheal extubation predicts improved postoperative outcomes and late survival after cardiac surgery. We also evaluated the optimal timing of extubation and its association with better postoperative outcomes. METHODS Between 2002 and 2006, 1164 patients underwent early tracheal extubation (<6 hours after surgery) and 1571 had conventional extubation (>6 hours after surgery). Propensity score adjustment and multivariable logistic regression analysis were used to adjust for imbalances in the patients' preoperative characteristics. Receiver operating characteristic curves (ROC) were used to identify the best timing of extubation and improved postoperative outcomes. Cox regression analysis was used to identify whether early extubation is a risk factor for decreased late mortality. RESULTS Results - Early extubation was associated with lower propensity score-adjusted rate of operative mortality (Odds Ratio =0.55, 95% Confidence Intervals =0.31-0.98, p=0.043). Extubation within 9 hours emerged as the best predictor of improved postoperative morbidity and mortality (sensitivity =85.5%, specificity =52.7%, accuracy =64.5%). Early extubation also predicted decreased late mortality (Hazard Ratio =0.45, 95% Confidence Intervals 0.31-0.67, p<0.001). CONCLUSIONS Early extubation may predict improved outcomes after cardiac surgery. Extubation within 9 hours after surgery was the best predictor of uncomplicated recovery after cardiac surgery. Those patients intubated longer than 16 hours have a poorer postoperative prognosis. Early extubation predicts prolonged survival up to 16 months after surgery.

Continuous quality improvement program and major morbidity after cardiac surgery. Am J Cardiol 2008; 102:772-7.

Abstract
The aim of this study was to investigate how a continuous quality improvement (CQI) program affected major morbidity and postoperative outcomes after cardiac surgery. Patients were divided into 2 groups: those who underwent surgery (coronary artery bypass grafting, isolated valve surgery, or coronary artery bypass grafting and valve surgery) after the establishment of a CQI program (from January 2005 to December 2006, n = 922) and those who underwent surgery beforehand (from January 2002 to December 2003, n = 1,289). Patients who had surgery in 2004, when the system and processes were reengineered, were not included in the analysis. Outcomes compared between the 2 groups included (1) acute renal failure, (2) stroke, (3) sepsis, (4) hemorrhage-related reexploration, (5) cardiac tamponade, (6) mediastinitis, and (7) prolonged length of stay. Logistic regression analysis and propensity score adjustment were used to adjust for imbalances in the patients' preoperative characteristics. After propensity score adjustment, CQI was found to decrease the rate of sepsis (odds ratio [OR] 0.5, 95% confidence interval [CI] 0.3 to 0.9, p = 0.02) and cardiac tamponade (OR 0.2, 95% CI 0.04 to 0.8, p = 0.02) but to only marginally decrease the rate of acute renal failure (OR 0.7, 95% CI 0.5 to 1.0, p = 0.07). CQI did not emerge as an independent risk factor for hemorrhage-related reexploration, prolonged length of stay, mediastinitis, or stroke in either multivariate logistic regression analysis or propensity score adjustment. In conclusion, the systematic implementation of a CQI program and the application of multidisciplinary protocols decrease sepsis and cardiac tamponade after cardiac surgery.

Abstract
BACKGROUND Early changes in sternal perfusion were studied after midline sternotomy and different methods of mammary artery (MA) harvesting. METHODS Our observations were made in the swine model after midline sternotomy. In group 1 (6 animals), after unilateral skeletonized MA harvesting, (99m)Tc particles were injected intravenously. In group 2 (7 animals), after unilateral mammary artery and vein harvesting (semiskeletonized technique), (99m)Tc particles were injected intravenously. In group 3 (5 animals), after skeletonized bilateral MA harvesting, 99mTc particles were injected into the intercostal musculature lateral to the sternal border. In groups 1 to 3, sternal samples were analyzed using gamma counting. In group 4 (6 animals), unilateral skeletonized MA harvesting was performed. In group 5 (5 animals), the MA was harvested unilaterally using the semiskeletonized technique. In groups 4 and 5, sternal blood flow was assessed using thermography. Data were collected in all groups for 5 hours postoperatively. RESULTS Both radioactive and thermographic flow measurements showed a statistically significant decrease in sternal blood flow on the side of harvested mammary vessels, regardless of harvesting technique. Radioactivity of the devascularized hemisterni on the side of intramuscular particle injection was substantially higher than in the contralateral half, confirming the role of diffusion in sternal nourishment. The distal sternal segments were least perfused by the MA. CONCLUSIONS There is an acute reduction of sternal perfusion during the early postoperative period, even if collaterals are preserved by skeletonized MA harvesting. Diffusion plays an important role in sternal nourishment, particularly of the xiphoid, and even more so after MA harvesting.

Abstract
The extracranial carotid artery is the most common site for peripheral vascular procedures. Although the association of carotid disease and neurologic dysfunction was understood by the ancient Greeks, over 1700 years would pass before the relevant anatomy was described. In the 16th and 17th centuries, attempts at treatment of carotid injury and aneurysm by ligation were met with extremely high rates of stroke and death. It is not until the mid 20th century, with the introduction of carotid angiography and improved vascular surgical techniques, that the era of reconstructive carotid surgery begins. We present a synopsis of the history of carotid surgery from ancient times to present day.

Abstract
When pulmonary embolism occurs in the presence of a patent foramen ovale the sudden increase in the right heart pressure can open the defect and could cause right to left atrial shunting. This may further aggravate the already existing hypoxemia, and the direct communication between the venous and the arterial circulation increases the risk of paradoxical embolization. In this paper we present a case of postoperative pulmonary embolization in a patient with patent foramen ovale, and the effects of these co-existing conditions are reviewed. In the cardiac surgical literature such a complication has not yet been described.

Abstract
Symptomatic bronchogenic cysts should be completely resected because of uncertainties in diagnosis, to prevent recurrence, and to avoid late complications. Infrequently, these cysts may involve the proximal tracheobronchial tree. Often such cysts are incompletely excised with less than optimal results. A case of a patient with a bronchogenic cyst involving the wall of the right mainstem bronchus is presented. The cyst was completely excised and the bronchus repaired using a pedicled pericardial flap. The procedure may serve as the preferred method of reconstruction in such circumstances.

Abstract
Since antiquity, clinicians have observed that maggots can provide debridement of necrotic wounds, but the therapeutic use has declined since the advent of aseptic wound management and antibiotics. In certain difficult wounds, the use of maggots for debridement may have a role. If so, the larvae must be prepared prospectively to control the bacterial population of the insect's intestinal tract and integument. The mechanism of wound debridement by maggots includes the secretion of proteolytic enzymes and antibacterial substances. A case of infestation of a necrotic wound in a patient with cancer of the head and neck is presented including the entomological identification and description of the maggots.
