Video-Assisted Thoracic Surgery Sleeve Lobectomy: A Case Series

Ali Mahtabifard; Clark Fuller; Robert J. McKenna

BACKGROUND As thoracic surgery moves towards more minimally invasive procedures, such as video-assisted thoracic surgery (VATS) lobectomy, conversion from a VATS to open thoracotomy has been required for a sleeve resection. This article reports a large experience of VATS sleeve lobectomy. METHODS We reviewed our thoracic surgery database of more than 1500 VATS lobectomies for VATS sleeve resections. Preoperative, operative, and perioperative outcome variables, including morbidity and mortality were examined. RESULTS Identified were 13 patients (median age, 59 years; range, 16 to 82 years) who underwent VATS sleeve lobectomy. There were no conversions to thoracotomy. Diagnoses included non-small cell lung cancer in 8 patients, typical carcinoid in 4, and metastatic sarcoma in 1 patient. Median tumor size was 2.1 cm (range, 0 to 6.6 cm). Median data were operative time, 167 minutes (range, 90 to 300 minutes); blood loss, 250 mL (range, 75 to 800 mL); chest tube drainage, 692 mL (range, 459 to 1590 mL); and chest tube duration, 3 days (range, 2 to 6 days). Median intensive care unit stay was 0 days (range, 0 to 4 days), and median hospital stay was 3 days (range, 2 to 8 days). No complications occurred in 9 patients (69%). Morbidity in the remaining 4 patients included 1 patient each with atrial fibrillation, anastomotic stricture, reintubation, and bronchial tear requiring repair. There were no deaths at 30 days. CONCLUSIONS In experienced centers, VATS sleeve lobectomy is possible with acceptable morbidity and mortality as well as short length of stay.

Wedge Resection and Brachytherapy for Lung Cancer in Patients With Poor Pulmonary Function

BACKGROUND Although lobectomy is the standard for lung cancer because a wedge resection has a 3 to 5 times greater incidence of local recurrence, poor pulmonary function may preclude lobectomy. For these patients, low-dose-rate brachytherapy has recently been used to decrease local recurrence after sublobar resection. Current techniques expose operating room personnel and patient contacts to unnecessary radioactivity risks. We present our technique of sublobar resection combined with afterload catheters for high-dose-rate brachytherapy for patient benefit with minimal risk to others. METHODS Forty-eight patients (25 women, 23 men) underwent wedge resection, node dissection, and brachytherapy. A remote-afterloading high-dose-rate unit for radiation produced a median dose of 2450 cGy (350 cGy per fraction over 7 fractions twice daily for 4 days). The dose was prescribed to 1 cm deep to the stapled line. Biologically, this dose is approximately 5000 cGy and above (180 cGy/d equivalent) at the depth of 5 mm in reference to the resection margin. RESULTS Two patients died. The length of mean stay was 5.5 days (median, 5 days). Complications included prolonged air leak in 5 patients, atrial fibrillation in 5, pneumonia in 3, trapped lung in 2, and 1 each with empyema, bleeding, and recurrent laryngeal nerve injury. Three patients required a blood transfusion. Within the follow-up of 1 to 27 months, there were four recurrences. CONCLUSIONS Wedge resection and brachytherapy appears to be a reasonable treatment for patients with lung cancer and pulmonary function that prohibits a lobectomy.

BackgroundThis study was designed to assess the prevalence of smoking at time of lung cancer diagnosis in a surgical patient cohort referred for cardiothoracic surgery.MethodsRetrospective study of lung cancer patients (n = 626) referred to three cardiothoracic surgeons at a tertiary care medical center in Southern California from January 2006 to December 2008. Relationships among years of smoking cessation, smoking status, and tumor histology were analyzed with Chi-square tests.ResultsSeventy-seven percent (482) had a smoking history while 11.3% (71) were current smokers. The length of smoking cessation to cancer diagnosis was <1 year for 56 (13.6%), 1-10 years for 110 (26.8%), 11-20 years for 87 (21.2%), 21-30 years for 66 (16.1%), 31-40 years for 44 (10.7%), 41-50 years for 40 (9.7%) and 51-60 years for 8 (1.9%). The mean cessation was 18.1 ± 15.7 years (n = 411 former smokers). Fifty-nine percent had stage 1 disease and 68.0% had adenocarcinoma. Squamous cell carcinoma was more prevalent in smokers (15.6% vs. 8.3%, p = 0.028); adenocarcinoma was more prevalent in never-smokers (79.9% versus 64.3%, p = 0.0004). The prevalence of adenocarcinoma varied inversely with pack year (p < 0.0001) and directly with years of smoking cessation (p = 0.0005).ConclusionsIn a surgical lung cancer cohort, the majority of patients were smoking abstinent greater than one decade before the diagnosis of lung cancer.

Photodynamic Therapy Followed by Thoracoscopic Sleeve Lobectomy for Locally Advanced Lung Cancer

Daniel T. DeArmond; Ali Mahtabifard; Clark Fuller; Robert J. McKenna

Photodynamic therapy is an effective technique for debulking endobronchial tumors over an acceptably short time-course; however, to be effective, numerous treatment cycles may be required to achieve the desired results. We present a case in which photodynamic therapy was used with curative intent to downsize an obstructing endobronchial non-small cell lung cancer in advance of resection via video-assisted thoracoscopic surgery with right upper lobe sleeve lobectomy.
