Robot-Assisted Lobectomy for Early-Stage Lung Cancer: Report of 100 Consecutive Cases

BACKGROUND Robotics can facilitate dissection during video-assisted thoracoscopic (VATS) lobectomy. This study describes a hybrid minimally invasive lobectomy procedure consisting of two phases: robotic vascular, hilar, and mediastinal dissection, and then VATS lobectomy. METHODS Over a 54-month period, 100 consecutive patients with stage I and II (T1 or T2N0, and T1 or T2N1) lung cancer (42 men, 58 women; mean age 65 +/- 8 years) underwent robotic VATS lobectomy. RESULTS Lobectomies were right upper (29), right middle (7), right lower (17), left upper (31), and left lower (16). Mean operating room time was 216 +/- 27 minutes. Tumor type was adenocarcinoma (57), squamous cell carcinoma (25), 7 adenosquamous carcinoma (7), bronchoalveolar (3), large cell (1), poorly differentiated (3), carcinoid (2), mucoepidermoid (1), spindle cell (1). Pathologic upstaging was noted in 17 patients (10 to stage IIB, 7 to stage IIIA). There was no emergent conversion to a thoracotomy. Median hospitalization was 4 days. Complications included atrial fibrillation (13), atelectasis (5), prolonged air leak (4), pleural effusion (3), pulmonary embolus (3), incisional bleeding (1), hydropneumothorax (1), dural leak (1), liver failure (1), pneumonia (1), respiratory failure (1), and cardiopulmonary arrest (1). There was no intraoperative death. Postoperative mortality was 3%. There were no deaths among the last 80 patients. At a median follow-up of 32 months (range, 1 to 59), 1 patient (1%) died of his cancer, 6 (6%) had distant metastases, and 2 (2%) had a second lung primary cancer. There was no local recurrence. CONCLUSIONS Robotics are feasible for mediastinal, hilar, and pulmonary vascular dissection during VATS lobectomy.

Spontaneous pneumomediastinum: Diagnostic and therapeutic interventions

ObjectivesThe objective of this case series is to review our experience with spontaneous pneumomediastinum, review the available literature, and refine the current clinical approach to this uncommon condition.MethodsThe case notes of all patients admitted to the George Washington University Medical Center with spontaneous pneumomediastinum from April 2005 to June 2008 were retrospectively reviewed, indentifying seventeen patients on whom various data was collected and analyzed.ResultsThe typical patient is a young man. The commonest presenting complaint is chest pain. Odynophagia and subcutaneous emphysema are common. Leucocytosis is uncommon. The need for swallow studies, antibiotics, and prolonged hospitalization is uncommon. Most patients have no recurrences or sequelae on long-term follow-up.ConclusionSpontaneous pneumomediastinum is an uncommon, self-limiting condition. Due to concerns for the integrity of the aero-digestive tract, the finding of spontaneous pneumomediastinum usually results in unnecessary radiological investigations, dietary restriction and antibiotic administration with prolonged hospitalization.

Outpatient management of post-pneumonectomy and post-lobectomy empyema using the vacuum-assisted closure system

PurposeThe conventional management of a post-pneumonectomy (PPE) and post-lobectomy empyema (PLE) necessitates an open window, wound packing, frequent wound debridement, and prolonged hospitalization. We studied the feasibility of outpatient therapy in this patient population using the vacuum-assisted closure (VAC) therapy system.MethodsFrom September 2005 to November 2007, six patients with PPE and PLE with or without a bronchopleural fistula underwent outpatient therapy using a VAC system. After debridement and closure of the bronchial fistula, a VAC system was applied and the patient was discharged. The patient returned for debridement under anesthesia and VAC replacement every 7–10 days. Once the pleural space was cleaned, the residual space was obliterated, and the wound was closed over suction catheters. Of the six patients, two developed recurrent infection after the closure that required repeated VAC dressings and flap closures.ResultsThe outpatient use of the VAC system in patients with PPE and PLE avoided the need for any daily painful dressing changes and significantly decreased the total length of hospitalization and the time to closure of the empyema space, and thus increased the overall patient satisfaction.ConclusionsOur results suggest that outpatient VAC therapy of PPE and PLE is feasible and beneficial.

Novel thoracoscopic approach to posterior mediastinal goiters: report of two cases

Trans-cervical resection of posterior mediastinal goiters is usually very difficult, requiring a high thoracotomy. Until recently, using conventional video-assisted thoracoscopic surgery to resect such tumors has been technically difficult and unsafe. By virtue of 3 dimensional visualization, greater dexterity, and more accurate dissection, the Da Vinci robot, for the first time, enables a completely minimally invasive approach to the posterior superior mediastinum.

Robotic-assisted treatment of celiac artery compression syndrome: Report of a case and review of the literature

The surgical management of celiac artery compression syndrome (CACS) is controversial. Controversies include the appropriate surgical technique, the surgical approach, and the utility of postoperative stents. The literature is reviewed, and a case of CACS is presented in which a robotic‐assisted division of the median arcuate ligament (MAL) was performed.

Robot-Assisted Thoracoscopic Resection of Intralobar Sequestration

In this paper, we report the first case of a robot-assisted thoracoscopic resection of intralobar sequestration. By virtue of greater dexterity and three-dimensional visualization, the da Vinci robot enables a safer, more precise dissection of sequestered tissue in the face of chronic inflammatory adhesions than conventional video-assisted thoracoscopic surgery does. Thus, in expert hands, such robotic technology is likely to result in less bleeding complications and less conversions to open surgery in cases of sequestration.

Novel thoracoscopic approach to difficult posterior mediastinal tumors

Thoracoscopic resection is the preferred treatment of posterior mediastinal tumors. However, thoracotomy may be necessary if the tumors are large or adherent; if they are demonstrate invasion or intraspinal growth; or if they are located in the superoposterior mediastinum or posterior costodiaphragmatic angle. We describe a case of a large, adherent posterior costodiaphragmatic mediastinal mass that would have been otherwise difficult to resect thoracoscopically if it were not for the three-dimensional visualization, greater dexterity, and accurate dissection offered by the Da Vinci robot.
