Thoracic enhanced recovery with ambulation after surgery: a 6-year experience.

OBJECTIVES: Our institution implemented a protocol known as thoracic enhanced recovery with ambulation after surgery (T-ERAS) in thoracic operations. The objective was early ambulation starting in the postoperative ambulatory care unit. METHODS: Video-assisted thoracoscopic surgery lobectomy patients are placed on a chair in the preoperative area and then walked to the operating room. Postoperatively, patients are placed on a chair as soon as possible. Our target ambulation goal was 250 feet within 1 h of extubation. Patients then walk to their hospital room. T-ERAS adoption and outcomes were compared to a pre-T-ERAS period, in addition to the comparing early and late T-ERAS cohorts. RESULTS: Over 6 years, 304 patients on T-ERAS underwent a planned video-assisted thoracoscopic surgery lobectomy. Median age was 67 years (range 41-87 years). The target goal was achieved in 187 of 304 (61.5%) patients and 277 of 304 (91.1%) patients ambulated 250 feet at any time in the postoperative ambulatory care unit. The T-ERAS period had a median length of stay of 1 day vs 2 days in the pre-T-ERAS period (P < 0.001). There were low rates of pneumonia (2/304, 0.7%), atrial fibrillation (12/304, 4.0%) and no postoperative mortalities for T-ERAS. The target goal was achieved at a greater rate in the late (92/132, 72.0%) versus early (28/75, 37%) T-ERAS cohort. The mean time to ambulation was reduced in the late cohort (46-81 min). CONCLUSIONS: Early postoperative ambulation was feasible and considered key in achieving low morbidity after video-assisted thoracoscopic surgery lobectomy. Adoption of T-ERAS improved over time. Further studies will help define adoptability at other sites and validate impact on improving outcomes.

Using an epidemiological framework and bovine spongiform encephalopathy investigation questionnaire to investigate suspect bovine spongiform encephalopathy cases: an example from a bovine spongiform encephalopathy case in Ireland in 2015.

In several EU member states, bovine spongiform encephalopathy (BSE) cases have been identified in cattle born after the reinforced ban (BARB cases), for reasons that are not entirely clear. Epidemiological investigation of these cases has proved challenging. The European Food Safety Authority recently recommended the collection of a predefined set of epidemiological data from BSE suspects and confirmed BSE cases to aid future investigations. In this study, we present an epidemiological framework and BSE investigation questionnaire to aid the investigation of suspect BSE cases, and illustrate its application during the investigation of a BSE case in Ireland in 2015. It is recommended that the framework and questionnaire are used concurrently: the framework provides structure and focus, whereas the questionnaire (with 135 questions) aids data collection. The framework focuses on confirmation and discrimination, estimating the date and location of exposure, and determining the method/source of exposure. The BSE case in Ireland in 2015 was a BARB case born in 2010. It was identified with classical BSE at an authorised knackery as part of Ireland's targeted active surveillance programme for BSE. No definitive source of infection with the BSE agent could be attributed in this case.

Thoracic surgery in octogenarians: CVTSA/Inova Fairfax hospital experience, 1990 to 2009.

With an increasing proportion of U.S. individuals 80 years of age or older, the authors examined their surgical experience with octogenarians undergoing major, curative-intent thoracic surgery. Between January 1, 1990, and September 1, 2009, 102 octogenarians underwent curative-intent resection for nonsmall cell carcinoma of the lung (NSCCL), esophageal carcinoma (EC), or related surgery for thoracic esophageal perforation (EP). Analysis and reporting followed the guidelines of the Nationwide Inpatient Sample database study (1994 to 2003). Eighty-six patients underwent curative-intent resection for NSCCL, 12 for EC, and four for surgery for EP. Hospital and 30-day mortalities were 0 per cent. Overall 1-, 2-, and 5-year survival rates were: 78, 58, and 32 per cent. Within the NSCCL cohort, minimally invasive exposures (video-assisted thoracic surgery [VATS] and video thoracoscopy [VT]) were associated with fewer and shorter duration of air leaks, leading to shorter length of stay. Since we began using minimally invasive exposure for NSCCL in 2007, the percentage of octogenarians discharged within 5 days of surgery has increased from 35.5 to 66.7 per cent (P = 0.01), and the percentage of patients discharged within 3 days of surgery has increased from 8.1 to 33.3 per cent (P = 0.006). Of 24 patients undergoing surgery for NSCCL since 2007, 18 (75%) underwent minimally invasive (VATS or VT) exposures, of which 15 patients (83.3%) were discharged home within 5 days and eight (44.4%) within 3 days of their procedure. Excellent, short- and longer-term results can be achieved in elderly patients if risks, exposures, and resections are appropriately matched to patient performance.

Thoracic esophageal perforations.

The authors review their experience with thoracic esophageal perforation at Inova Fairfax Hospital, June 1, 1988, to March 1, 2009. With the exception of 6 patients with occult perforation, all of whom survived with nonoperative therapy, aggressive surgical intervention was the standard approach. Among patients treated aggressively with surgery within 24 hours of perforation, hospital survival was 97 per cent versus 89 per cent for patients treated aggressively surgically after 24 hours. In the absence of phlegmon, implacable obstruction, or delay, primary repair resulted in 100 per cent survival. Where phlegmon or resolute obstruction existed, resection and reconstruction resulted in 96 per cent survival. Even when patients were deemed too ill to undergo surgery, cervical diversion was 100 per cent effective in eradicating continuing leak and achieved 89 per cent survival. Endoesophageal stenting was applied as primary treatment or secondarily such as where leak complicated primary repair. When stenting was used as the initial and primary treatment modality, survival was 88 per cent. Targeted drainage was helpful on occasion as an adjunct to initial therapies. Comfort measures alone were appropriate when clinical circumstances merited no effort at resuscitation. Finally, survivors were asked to self-categorize their ability to swallow; 95 per cent responded good to excellent.

Multimodality treatment for esophageal malignancy: the roles of surgery and neoadjuvant therapy.

The best curative treatment for esophageal malignancy remains controversial. In 2003, we presented our institution's experience with 124 patients treated from 1990 to 2001. Here we update that experience with an additional 6 years' data. A total of 221 patients underwent surgical resection from 1990 to 2007; 128 had up-front surgery, 88 underwent surgery after neoadjuvant radiation and chemotherapy (NARCS), and five underwent surgery after neoadjuvant, single-agent therapy. Principle outcomes of interest were 30-day and in-hospital mortality as well 3- and 5-year survival rates. Overall 3- and 5-year survival rates were 38 and 33 per cent. NARCS achieved complete pathologic result in 32 per cent of patients with corresponding 3- and 5-year survival rates of 58 and 53 per cent. The 3- and 5-year survival rates for all patients undergoing NARCS were 36 and 31 per cent versus 24 and 18 per cent for patients with up-front surgery for anything over Stage I disease (P = 0.01). The 3- and 5-year survival rates for patients with up-front resection of Stage I disease were 78 and 70 per cent. Overall, 30-day and in-hospital mortalities were 1.8 and 2.3 per cent. Since January 1, 2000, hospital mortality has been less than 0.8 per cent. We prefer NARCS for malignancy of the esophagus, except in those patients with high-grade dysplasia (carcinoma in situ), suspected Stage I disease, poor performance status, or urgent/emergent circumstances.

Late stage (III and IV) non-small cell cancer of the lung: results of surgical resection at Inova Fairfax Hospital.

One hundred forty-two patients underwent surgery and related treatment for advanced stage (III, IV) non-small cell cancer of the lung. One hundred seventeen patients underwent up-front surgery, with a hospital mortality rate of 1.7% (2/117). Kaplan-Meier 5-year survival in this group was 31% (+/- 5). Twenty-five patients underwent neoadjuvant therapy followed by surgical resection, with respective rates of hospital mortality, complete pathologic response, and major pathologic response of 0%, 16%, and 64%. Kaplan-Meier 5-year survival in this latter group was 34% (+/- 11). Of the 16 patients undergoing neoadjuvant therapy who had complete pathologic response or significant downstaging from stage III disease, Kaplan-Meier 5-year survival was 61% (+/- 15). Three clinical observations of interest emerged regarding survival. First, in those patients with postresection FEV1 < 1.0 L, hospital mortality rate was 20%, and there were no 5-year survivors (P < 0.0001). Second, where neoadjuvant therapy was associated with complete pathologic response or significant downstaging of disease, there was a trend for improved survival in the downstaged group, but it did not reach statistical significance (P = 0.14). Third, adjuvant therapy was associated with improved 5-year survival (P = 0.03), particularly for combination chemotherapy and radiotherapy (P = 0.02).

A pragmatic and successful approach to treating nonsmall-cell lung carcinoma.

Lung cancer is the single leading cause of cancer deaths for men and women combined. Nonsmall-cell lung carcinoma (NSCLC), which results largely from smoking tobacco, accounts for 87% of all lung cancer cases. Methods of patient selection, preoperative and intraoperative care, and postoperative outcomes for patients with NSCLC who were treated from 1991 through 2003 at Inova Fairfax Hospital are discussed. All patients were treated with surgery, some selectively and progressively with a combination of preoperative neoadjuvant therapy, to try to downstage the disease to make complete resection feasible. Outcomes from this data collection period match or exceed the best results for treatment of late-stage (ie, III and IV) disease reported anywhere to date.

Multimodality treatment for esophageal cancer: the role of surgery and neoadjuvant therapy.

Treatment of esophageal cancer has traditionally included surgery as the initial modality. Neoadjuvant chemoradiation therapy has been introduced with the goal of downstaging tumors before surgical resection; however, its role in esophageal cancer remains controversial. We report 116 patients who underwent esophagogastrectomy with reconstruction for carcinoma of the esophagus or esophagogastric junction over a 10-year period (January 1, 1990 to June 1, 2001). Forty patients underwent neoadjuvant radiation and chemotherapy followed by surgery. Hospital mortality in this group was 7.5 per cent, complete pathologic response (CPR) was 37.5 per cent, and overall 3- and 5-year survival rates were 47 and 38 per cent. Five-year survival in the 15 patients with CPR was 85 per cent. Five patients underwent neoadjuvant single-agent therapy (four chemotherapy and one radiation) followed by surgery, and none survived to 3 years. Seventy-one patients underwent surgery without neoadjuvant therapy. Hospital mortality in this group was 1.4 per cent, with 3- and 5-year survival of 21 and 17 per cent--a decreased long-term survival compared with the neoadjuvant therapy group despite the observation that patients who underwent neoadjuvant therapy had a larger tumor size on presentation (5.5 +/- 0.4 cm vs 3.8 +/- 0.2 cm; P = 0.002). Squamous cell carcinomas seemed to be more responsive to neoadjuvant radiation and chemotherapy followed by surgery than were adenocarcinomas, with a CPR of 44.4 versus 35.5 per cent; however, 5-year survival rates in these complete responders were not significantly different (100% and 78%, respectively; P = 0.97). We report that esophagogastrectomy in conjunction with neoadjuvant therapy results in increased survival compared with surgery without neoadjuvant therapy (P < 0.01), although there may be an increased perioperative mortality associated with neoadjuvant therapy. Further studies are needed to evaluate the role of preoperative chemoradiation and to better identify the pretreatment characteristics of patients with a complete pathological response.

Thoracic esophageal perforations.

BACKGROUND: Recognition of the importance of early diagnosis and aggressive, definitive surgical intervention has brought about a dramatic decline in mortality related to distal esophageal perforation. METHODS: We retrospectively analyzed all cases of thoracic esophageal perforation diagnosed at our hospital from September 1, 1979, through April 1, 2001. The study group consisted of 62 patients (43 men) with a mean age of 58.8 years (range, 20-92 yr). RESULTS: In the group of 39 patients with early diagnosis (< or = 24 h), hospital survival was 87%, which increased to 93% when early diagnosis was combined with aggressive surgical treatment Among the 23 patients with late diagnosis (> 24 h), survival approached 70%. Yet, in patients who were treated aggressively with surgery, survival was almost 90% despite delayed diagnosis. CONCLUSION: We recommend aggressive, definitive surgery for thoracic esophageal perforations, whether diagnosed early or late. A variety of options are discussed with regard to complicated presentations.

Mediastinal staging of non-small cell lung carcinoma using computed and positron-emission tomography.

BACKGROUND: We evaluated the accuracy of computed tomography (CT) and positron-emission tomography (PET) in the mediastinal staging of non-small cell lung cancer. METHODS: Between May 14, 1999, and November 28, 2000, computerized tomography (CT) and positron-emission tomography (PET) were used to clinically stage 94 consecutive patients with non-small cell carcinoma of the lung (NSCCL). All patients underwent subsequent surgical staging with mediastinoscopy, anterior mediastinotomy, and/or thoracotomy with mediastinal lymphadenectomy. RESULTS: Overall accuracy was the same for both procedures. False-negative results occurred 3 times more often with CT; false-positive results occurred twice as often with PET. Sensitivity and specificity were 64% and 94%, respectively, for CT, versus 88% and 86%, respectively, for PET. Positive and negative predictive values were 80% and 88%, respectively, for CT, versus 71% and 95%, respectively, for PET. CONCLUSION: In addition to routine use of CT, PET seems to achieve high negative predictive value in the evaluation of mediastinal disease; PET seems particularly helpful in assessing absence of tumor in bulky nodes after neoadjuvant chemotherapy and/or radiotherapy.
