Fast-tracking protocols or postoperative care computerized algorithms have been shown to reduce hospital LOS and reduce costs for patients. who undergo both open and VATS procedures The ability to fast-track is not governed by the type of procedure (closed versus open), but rather by patient characteristics and the mindset of the operating surgeon and the postoperative care team. While use of protocols enhance the ability of many physicians to fast-track many different types of patients, it is a mistake to force these protocols on all patients because, if not modified, they can lead to increased complications, readmissions, and low patient and family satisfaction. By carefully analyzing surgical results using accurate prospective databases, the types of patients who fail fast-tracking and the reasons they fail can be identified. Specific changes to the postoperative algorithms can be implemented and these alterations can lead to improved outcomes. For example, we have shown that by using pain pumps instead of epidurals in elderly patients we can improve outcomes and still fast-track octogenarians with minimal morbidity and high patient satisfaction. We have also shown that the use of increased physical therapy and respiratory treatments (important parts of the care of all patients after pulmonary resection, but a limited resource in most hospitals) may also lead to improved surgical results for those with low FEV1% and DLCO%. Although fast-tracking protocols cannot be applied to all, the vast majority of patients who undergo elective pulmonary resection, even those at high risk, can undergo safe, efficient and cost-saving care by way of preset postoperative algorithms after VATS or thoracotomy procedures. When the typical daily events are communicated each morning and the planned date of discharge is reinforced with the patient and family before surgery and each day in the hospital on rounds, most patients can be safely fast-tracked with high satisfaction and outstanding results.

BACKGROUND: Air leaks remain the most common pulmonary complication after elective pulmonary resection, yet their assessment, unlike other clinical bedside indicators, remains analogue and not digital. METHODS: This prospective randomized study compared a digital air leak system with the current analogue air leak system in 100 patients that underwent elective pulmonary resection. RESULTS: The digital and analogue patient groups each had 50 patients. Pulmonary function, types of pulmonary resection, number of chest tubes, and pathology were not statistically different between the groups. The digital system confirmed the air leak status in 5 patients that were equivocal on the analogue system. The ability to assess the air leak status continuously afforded quicker chest tube removal in the digital group (mean, 3.1 vs 3.9 days, p = 0.034) and reduced hospital stay (mean, 3.3 vs 4.0 days, p = 0.055). Three patients were discharged home with the device, without complications. CONCLUSIONS: The digital and continuous measurement of air leaks instead of the currently used static analogue systems reduces hospital length of stay by more accurately and reproducibly measuring air leaks. This leads to quicker chest tube management decisions because the average size of an air leak during the last several hours can be determined. Intrapleural pressure curves may also help predict the optimal chest tube setting for each patient's air leak and eliminate the need for chest roentgenograms. Further studies on the pleural pressure curves and this device are needed.

BACKGROUND: The objective of this study was to determine the survival of patients who have completely resected, nonsmall-cell, stage IIIA, lung cancer from unsuspected (nonimaged) N2 disease who received adjuvant chemotherapy. METHODS: This is a retrospective cohort study using a prospective database. All patients underwent positron emission tomography scan and computed tomography scan with contrast, R0 resection with complete thoracic lymphadenectomy, and had unsuspected, pathologic N2 NSCLC. RESULTS: Between June 1998 and December 2007, there were 148 patients (89 men). The most common pulmonary resection was right upper lobectomy in 67 patients (48%), and the most common lymph node station for unsuspected N2 diseased was 4R. One hundred and thirty-seven patients (93%) received adjuvant chemotherapy and 13% received postoperative radiation as well. The overall 2- and 5-year survivals were 58% and 35%, respectively. The 5-year survival for the 98 patients with single lymph node disease compared with patients with multiple nodal involvement was 40% versus 25%, respectively (p = 0.028). The number of lymph nodes involved (p = 0.032) was an independent predictors of survival on multivariate analysis. Median follow-up was 54 months. CONCLUSIONS: The 5-year survival of patients with unsuspected N2 disease who undergo complete resection, followed by adjuvant therapy, is 35%. Patients with single station N2 disease fare better. The role for mediastinoscopy, endoscopic esophageal ultrasound with fine-needle aspirate, or endobronchial ultrasound in patients who are negative by positron emission tomography and computed tomography is unknown, since the benefit of neoadjuvant therapy in these patients is also unproven. A randomized study is needed.

Angiomyolipoma is a benign tumor composed of varying proportions of smooth muscle cells, blood vessels, and adipose tissue that most commonly occurs in the kidney. Sporadic lesions and lesions arising in the setting of the tuberous sclerosis complex have been reported in extrarenal sites. We present the case of an incidentally discovered angiomyolipoma in the anterior mediastinum. Thymoma was suspected clinically, and the lesion was composed mainly of spindled-to-epithelioid cells arranged in a histologic pattern reminiscent of hemangiopericytoma, a pattern that has been described in thymoma. Immunohistochemical stains revealed positivity for smooth muscle actin and HMB-45, revealing the expression of smooth muscle and melanocytic markers characteristic of angiomyolipoma and other lesions in the PEComa family.

OBJECTIVE: Examination of factors that may contribute to racial disparity among those with lung cancer has been thwarted by heterogeneous treatment and staging strategies, limited national registry and socioeconomic and follow-up data. This study examines a decades worth of data to better elucidate these factors in a cohort staged or treated using homogeneous algorithms. METHODS: A nested case-control study of patients with non-small cell lung cancer (NSCLC). White patients were matched 4:1 to African American patients on age, gender, comorbidities, performance status, and stage. All patients underwent clinical and pathologic staging by one physician using similar staged-based treatment algorithms. Socioeconomic status was assessed by annual income per capita, insurance status, and education level. The primary outcome was survival rate. RESULTS: Among the 930 patients in this series, African Americans were more likely to be smokers (p < 0.001), have a lower per-capita annual income (p = 0.016), greater delay to treatment (p = 0.023), and less likely to agree to neo-adjuvant therapy (p < 0.001). Whites had better 5-year overall survival than African Americans for stage I (84% versus 78%, p = 0.037), stage II (52% versus 44%, p = 0.041), and stage III (32% versus 20%, p = 0.008) NSCLC. However, this survival advantage disappeared for earlier stages of NSCLC (I and II) when adjusted for socioeconomic status and smoking status. The survival advantage for stage IIIa was lost when adjusted for neo-adjuvant chemoradiotherapy. African American men had the worst survival of all subgroups independent of socioeconomic status. CONCLUSIONS: Given uniform staging, treatment, and socioeconomic status the overall survival rates for African American and White patients with NSLC are similar.

BACKGROUND: Patients with calcified mediastinal lymph nodes who have hemoptysis or lithoptysis represent a challenging therapeutic dilemma. METHODS: We performed a retrospective review of a prospective clinic and operative database between January 1998 and December 2006. All patients had calcified mediastinal lymph nodes, symptoms or complications from these nodes, or both. RESULTS: There were 50 patients (23 men). Thirty-eight (76%) were symptomatic, which included hemoptysis in 11, persistent cough in 8, and recurrent pneumonia in 5, and all underwent rigid bronchoscopy. Thirty-four (89%) of the 38 symptomatic patients had stones eroding into the airway (broncholiths), and 2 had an airway esophageal fistula. The most common location of the broncholith was in the bronchus intermedius (n = 19). Endoscopic removal of the broncholith was performed in 29 patients and was successful in all. Elective thoracotomy with lymph node curettage, removal, or both was performed in 5 patients. These 5 patients had no significant morbidity and no operative mortality. Patients remained symptom free (median follow-up, 2.3 years; range, 8-42 months). Twelve asymptomatic patients with calcified lymph nodes were followed with serial computed tomographic scans and remain asymptomatic (median follow-up, 3.1 years). CONCLUSIONS: Broncholiths that are not fixed to the airway can be safely removed with rigid and flexible bronchoscopic equipment. Thoracotomy with broncholithectomy is also safe and effective and is reserved for symptomatic lesions that cannot be removed bronchoscopically or for lesions that cause airway esophageal fistulas. Calcified nodes in asymptomatic patients are not an indication for intervention.

BACKGROUND: The pain of thoracotomy may be related to trauma to the intercostal nerves. METHODS: This was a prospective randomized study of 160 patients. All patients had a functioning epidural, similar type and size thoracotomy, an intercostal muscle flap (ICM) harvested before rib spreading, inferior rib drilling, and postoperative pain management. In one group, the ICM was left intact distally and it dangled (D group); the ICM in the other was cut distally (C group). Pain was assessed using multiple pain scores. Outcomes assessed were qualitative and quantitative pain scores, number of ribs broken, spirometric values, analgesic use, and return to baseline activity for postoperative days 1 to 5 and weeks 2, 3, 4, 8, and 12. RESULTS: The D group had 85 patients and the C group, 75. The groups had similar demographics, types of procedures, and histology. Intrahospital pain scores were similar; however, at postoperative weeks 3, 4, 8, and 12, the D group had significantly lower mean numeric pain scores and was using fewer analgesics (p < 0.05 for all). At 12 weeks, patients in the D group were more likely to have returned to baseline activity (p = 0.002). CONCLUSIONS: An ICM flap reduces pain. Harvesting and then leaving the ICM flap intact instead of cutting it before rib spreading further reduced thoracotomy pain. This technique, when added to rib drilling, leads to reduced pain on postoperative weeks 3 to 12, to quicker return to baseline activity, and lessens the need for analgesics.

BACKGROUND: Subcutaneous emphysema (SE) after pulmonary resection is troublesome and has been poorly studied. METHODS: A retrospective review was made of a prospective database. Patients who underwent pulmonary resection and in whom clinically detected SE were studied. RESULTS: Of 4,023 patients between January 1999 and June 2006, 255 patients (6.3%) had clinically apparent SE. Predictors of developing SE by multivariate analysis were preoperative forced expiratory volume of air in 1 second (FEV(1)%) less than 50%, having an air leak, and having had a previous thoracotomy. Despite maximizing chest tube suction, 85 patients (33%) had recalcitrant SE. These patients with recalcitrant SE were more likely to have a lower median FEV(1)% (p = 0.037), a previous ipsilateral thoracotomy, and have undergone a lobectomy (p < 0.001). Recently, 64 of the 85 patients underwent single-incision, video-assisted thorascopic surgery with pneumolysis and chest tube placement, which successfully resolved the SE within 24 hours in all patients except 1. These 64 patients had a significantly shorter hospital stay (6 versus 9 days, p = 0.02) and less time with recalcitrant SE than the other 21 patients. CONCLUSIONS: Subcutaneous emphysema is more likely in patients who have an FEV(1)% less than 50% and who undergo a redo thoracotomy. Recalcitrant SE emphysema (SE that persists despite increasing chest tube suction) is more likely in patients who undergo lobectomy and is best treated by video-assisted thorascopic surgery with pneumolysis between the leaking lung, which is usually partially adhered to the previously opened intercostal space. This directs the air leak back into the pleural space and out of the subcutaneous space. This procedure shortens the duration of SE and hospital stay.

BACKGROUND: The purpose of this study was to investigate differences in epidemiology, types of presentation, time between diagnosis and treatment, tumor characteristics, and survival in patients 45 years or younger with non-small cell lung cancer. METHODS: A nested case-control study was conducted during 7 years using a prospective database of patients with non-small cell lung cancer. Younger patients (<45 years of age) were matched 1:2 with older patients for stage, sex, performance status, and type of resection. RESULTS: There were 762 patients (254 were <45 years old, 508 controls were older). The median time from initial symptom to thoracic surgical consultation was significantly longer for those younger than 45 years (6.5 versus 2.8 weeks; p < 0.001). Younger patients were more likely to be symptomatic at the time of diagnosis (89% versus 68%; p < 0.001) and less likely to be smokers (45% versus 78%; p < 0.001). Kaplan-Meier analysis showed the time between diagnosis and treatment, symptoms, maximum standardized uptake value on positron emission tomography, and smoking status impacted survival. Only symptoms and smoking status impacted survival on Cox proportional hazards survival analysis among completely resected patients; 5-year survival was lower in the younger group compared with the older group (51% versus 62%; p = 0.037). CONCLUSIONS: Despite similar stages and tumor characteristics patients younger than 45 years of age with non-small cell lung cancer have a significantly worse prognosis than older patients. Although they are more likely to be symptomatic, younger patients have a greater delay in seeking thoracic surgical care. These data should be considered in the treatment strategy offered to younger patients with non-small cell lung cancer.

BACKGROUND: EUS-guided FNA is commonly performed to sample peri-intestinal targets such as the pancreas, lymph nodes, and the left adrenal gland. To our knowledge, EUS-guided FNA of the right adrenal gland has not been reported. OBJECTIVE: Our purpose was to determine the feasibility and success in sampling an enlarged right adrenal gland. STUDY DESIGN: Observational study. SETTING: Tertiary referral center. PATIENTS: Consecutive patients that underwent EUS-guided FNA of the right adrenal gland. RESULTS: Over a span of 3.5 years, 4 patients underwent transduodenal EUS-guided FNA of the right adrenal gland with a curvilinear echoendoscope. Four passes were performed in all cases, and the diagnosis was rendered on the first pass. The posterior wall of the descending duodenum was the port of entry of the needle. Three of the patients had metastatic lung cancer to the right adrenal gland; one was proven by surgical histopathologic examination. One patient had a benign aspirate consistent with angiomyolipoma. None of the patients had any minor or major complications. LIMITATIONS: Observational study, small sample size. CONCLUSIONS: Transduodenal EUS-guided FNA of the right adrenal gland is feasible and safe. Future large-scale studies are needed to replicate our findings and to determine the rate of successful identification and sampling of the right adrenal gland with the curvilinear echoendoscope.
