Methods. Thoracoscopic lobectomy was attempted in 110 consecutive patients (age, 35 to 81years) with tumors that were judged to be amenable to lobectomy over a 26-month period. Exclusion criteria included tumors greater than 5 cm in diameter, T3 tumors, endobronchial tumors visible at bronchoscopy, the use of induction therapy, extensive N1 disease on computed tomographic scan, and N2 disease at mediastinoscopy. The procedures were performed without rib spreading using two ports and included anatomic hilar dissection and individual vessel stapling.
Results. Thoracoscopic lobectomy and mediastinal lymph dissection was successfully performed in 108 patients (98.2%); 2 patients required conversion to thoracotomy to control bleeding in the setting of dense hilar adenopathy. There were no intraoperative deaths and 4 perioperative deaths (3.6%) caused by pneumonia and associated adult respiratory distress syndrome (3 patients) and stroke (1 patient). Major complications included pneumonia (5 patients), stroke (1 patient), and return to the operating room to revise the bronchial closure (1 patient). Minor complications included prolonged air leak (6 patients), atrial fibrillation (4 patients), blood transfusion (2 patients) and ileus (1 patient). Median time to chest tube removal was 3 days, and median length of stay was 3 days.
Conclusions. Thoracoscopic lobectomy is a safe and effective strategy for patients with early stage lung cancer. Long-term follow-up is required to determine if recurrence rate and 5-year survival are comparable with thoracotomy for lobectomy.

There are significant questions that remain unanswered among those surgeons who have not accepted TL as an appropriate oncologic procedure. Concerns include possible selection bias in the studies, the absence of large randomized, prospective trials, the lack of standardization of operative techniques to achieve a thoracoscopic lobectomy, questionable oncologic efficacy, and differences in whether mediastinoscopy, lymph node dissection, or sampling is performed in the available studies [1318].
This series reflects the experience with thoracoscopic lobectomy at a large, academic teaching institution by a single surgeon, using a standardized technique and limiting the operation to clinical stage I lung cancer patients. The objective of this study was to evaluate the technique for safety and efficacy in a large group of patients that could be followed up long-term in our thoracic oncology clinic.

Operative technique
All patients underwent bronchoscopy and mediastinoscopy, with frozen section of biopsy specimens, before proceeding with the thoracoscopic procedure. After mediastinoscopy, single lung anesthesia is established using a dual lumen endotracheal tube or bronchial blocker. The patient is turned to the lateral decubitus position and secured to prevent neurologic injury. Before sterile preparation and draping, the chest is marked for placement of thoracoscopic incisions.
We use two incisions: (1) a camera port in the seventh or eighth intercostal space in the midaxillary line (2 cm), and (2) an access port placed anteriorly in the fifth or sixth intercostal space (4.5 cm). Self-retaining retractors are not used. Additional incisions may be used, either posteriorly or superiorly, to provide optimal access for hilar dissection, retraction, and control of the pulmonary vascular structures. The anterior incision is positioned to provide adequate thoracoscopic visualization of the entire thorax, and most importantly, of the anterior hilar structures. Before making the anterior incision, evidence of unresectability, such as parietal pleural involvement, should be excluded. This anterior incision, in the fifth or sixth intercostal space, should be placed where the intercostal spaces are the widest and should be aligned with the major fissure. A 4- to 5-cm incision is this location allows access for multiple thoracoscopic instruments simultaneously, and provides for removal of the lobe in a protective specimen bag without difficulty.
After the placement of the anterior incision, the surgeon performs thoracoscopic exploration, division of the pulmonary ligament, and hilar mobilization. If a malignant diagnosis has not been achieved preoperatively, thoracoscopic wedge resection is performed using an automatic stapling device, such as the EndoGIA (US Surgical, Norwalk, CT), and the specimen is removed in a protective bag. After frozen section confirms a malignant diagnosis, thoracoscopic lobectomy may then be completed. In patients in which the lesions are located close to hilar structures, lobectomy is required to obtain diagnosis.
Mediastinal lymph node dissection may be performed at this point or may be deferred until the lobectomy has been completed. On the right, paratracheal lymph nodes (levels 2 and 4) are resected en bloc and separated on the back table. The subcarinal station (level 7) is resected after reflecting the lung anteriorly, exposing the inferior margin of the right main stem bronchus and carina. On the left, the aortopulmonary window lymph nodes and the anterior aortic nodes (levels 5 and 6) are dissected separately, with attention to preserving the recurrent laryngeal nerve. The subcarinal nodal station is more difficult to approach from the left side, but is accomplished with mobilization of the left inferior pulmonary vein.
Postoperative care
After the procedure, patients are taken to a cardiothoracic recovery area briefly; then they are transferred to a monitored cardiothoracic step-down unit for the remainder of their stay. The majority of patients do not receive epidural analgesia. Epidurals have been selectively used for some debilitated patients with other medical comorbidities, which would make it unlikely that they would resume normal activities in the immediate postoperative period; this population accounted for less than 10% of the patients. All other patients receive paravertebral blockade (T3 to T10) with 0.25% bupivicaine before operative induction and postoperative patient-controlled analgesia with intravenous narcotics for 24 hours. Pain symptoms are subsequently managed with oral narcotics depending on the severity of their pain symptoms. Ketorolac (Roche Laboratories) is also given for 24 hours postoperatively to patients without contraindications such as renal dysfunction, peptic ulcer disease, platelet dysfunction or bleeding diathesis. Chest tubes are removed after demonstrating no air leaks and less than 150 mL of fluid output for 24 hours.
Patient follow-up
Patients are seen in the clinic 2 weeks after discharge. They are subsequently followed-up at 4-month intervals for the first year with chest x-rays in the clinic, and annually thereafter. Data were collected on each patient including lobe resected, final pathologic stage and histology, time to chest tube removal, discharge from the hospital, complications, need for transfusion, reoperation, readmission, and tumor recurrence.

There were 22 complications documented in 21 patients (19.1%). Complications included air leak lasting longer than 7 days (6 patients), pneumonia (5 patients), atrial fibrillation (4 patients), lower extremity vascular insufficiency (2 patients), hemorrhage greater than 500 mL (2 patients), aspiration (1 patient), and stroke (1 patient). In another patient, the left upper lobe bronchus was narrowed during left lower lobectomy, which required subsequent bronchoplasty repair; the patient recovered with no further complications.
The median time to chest tube removal was 3 days (range, 1 to 53 days). The median length of stay was 3 days (range, 1 to 75 days). There were 2 patient readmissions in the group within 30 days of operation (1.8%). One patient was readmitted for ileus and the other for elective reoperation, who underwent thoracoscopic right lower lobectomy. Initial frozen section pathology showed mediastinal lymph nodes were all negative, but final pathology showed metastatic focus in a level 7 lymph node, as well as a concern that the tumor had crossed the fissure into the middle lobe. After counseling, the patient underwent thoracotomy for completion bilobectomy. There was no residual disease identified in the middle lobe, and further mediastinal lymph node dissection was entirely negative.
There were 4 deaths in the series during their postoperative hospital stay (3.6%). Three of the deaths were secondary to pneumonia and associated adult respiratory distress syndrome; the fourth death was caused by a massive postoperative stroke. There have been 2 additional deaths in the series, at approximately 2 months after resection and 1 year after resection from unrelated medical conditions.
The final pathologic diagnoses of the patients in this series are profiled in Table 1. Of the 110 patients in this series with preoperatively presumed lung cancer, 90 patients had pathologically confirmed lung cancer after their operation. Of the 90 patients with primary lung cancer, 79 were pathologic stage I (90%) (Table 3). Of the 11 patients who were upstaged from clinical stage I based on their operative pathology specimens, 5 patients were upstaged to stage II, and 3 were upstaged to stage IIIA. Three additional patients were upstaged to IIIB because of T4 tumor status secondary to satellite nodules in the resected lobe. At this time, there has been only 1 patient with documented recurrence (distant) in the 90 patients with lung cancer that underwent TL (1.1%).

The oncologic efficacy of TL lobectomy should be judged by the ability to achieve complete anatomic resection and to perform adequate mediastinal lymph node staging. TL provides complete and magnified visualization or the entire thorax, and the technique of TL involves individual vessel dissection and division. In this series, complete anatomic resection (with full hilar and mediastinal nodal dissection) was achieved in all patients. The completeness of resection, as measured by recurrence rate, is outstanding, as there are no local recurrences with a median follow-up of 16 months. There is one distant recurrence, involving a patient with a cerebral metastasis that was diagnosed 5 months after resection. It is also noteworthy that although studies have reported port site recurrences and dissemination of tumor from TL [19], we have not had any in our series.
Inadequate sampling and staging is considered by some surgeons and oncologists to be the greatest potential flaw of TL, as inadequate staging precludes appropriate treatment [2023]. In this group of patients with clinical stage I lung cancer, mediastinal lymph node dissection was accomplished in all, and 11 patients (12.5%) were upstaged based on operative findings and final pathology. The methods of lymph node dissection used in thoracoscopy are no different than the methods we use during open thoracotomy. As noted, all of our patients undergo bronchoscopy and mediastinoscopy before TL to appropriately define the extent of the disease.
The mortality rate in our series of 3.6% is comparable with other series [4, 5, 24, 25] and includes all patients regardless of comorbidities. Although we have not included objective data with regard to each of these patients, the series includes a large percentage of patients with compromised pulmonary function and significant conditions of comorbidity. Some authors have advocated TL for higher risk patients because of the potential limited physiologic stress associated with TL [25]. Although there is limited data on appropriate selection criteria for TL compared with open thoracotomy, we have noted favorable overall mortality in our patients regardless of their associated medical conditions.
As with other studies available with this technique [1, 7, 12, 13, 16], our series also demonstrates that patients had a short time to chest tube removal (median of 3 days) and short length of stay (median of 3 days), with a low readmission rate (2.8%). Though not objectively documented, as some other studies have shown [10, 11], our experience has provided us with the general impression that these patients experience less postoperative pain and need for narcotics compared with patients who underwent open operations concurrently on the service.
Finally, this experience at a large, academic teaching center has demonstrated TL to be a reproducible procedure with a high success rate (98.2%) and low overall complication rate (19.1%). This complication rate compares favorably with other thoracoscopic lobectomy series in the literature [1, 5, 7, 25]. It should be noted that the majority of cases were performed with assistance of cardiothoracic surgery residents. Because of the large volume of patients on our general thoracic surgery service, residents are active participants in the procedures and become facile with the procedure during their training. As this procedure becomes more common, we believe it should be readily teachable to surgeons with laparoscopic and thoracoscopic training, leading to more widespread use.
As this technique has been in existence for less than a decade, further long-term outcome studies are required to document its utility as an appropriate oncologic procedure. Sugi and colleagues [8] have reported 5-year follow-up data on a small series of TL patients and found recurrence and survival data to be excellent in stage I lung cancer patients. As experience continues to accumulate in the United States and other countries, we will be able to compare this technique with thoracotomy in larger series.
