Background: Pulmonary metastasectomy in patients with pulmonary metastases from primary colorectal cancer seems to improve survival in properly selected patients. Therefore, pulmonary metastasectomy has been incorporated widely into the management of colorectal pulmonary metastases. Generally, in patients presenting with primary colorectal cancer and synchronous pulmonary metastases, the primary colorectal cancer is resected first, followed by pulmonary metastasectomy during a second-stage procedure. In the current paper we describe our pilot experience with laparoscopic resection of primary colorectal cancer and thoracoscopic pulmonary metastasectomy during the same operative session.
Patients and methods: The results of two patients who underwent laparoscopic resection of primary colorectal cancer and thoracoscopic pulmonary metastasectomy during the same operative session are described.
Results: Both patients were healthy women, 60 and 81 years old, respectively, and without severe comorbidities. In both patients, the colorectal resection was performed first by a laparoscopic approach. Subsequently, thoracoscopic resection of a single pulmonary metastasis followed in both patients. The operative procedure and postoperative course were uneventful and the patients could be discharged within 1 week after surgery. Both the primary colorectal cancer and the pulmonary metastasis were radically removed in both patients. Current follow-up, 14 and 8 months after surgery, respectively, showed no signs of disease recurrence on computed tomographic scan of the abdomen and chest in both patients.
Conclusion: The outcome in these two patients suggests that simultaneous resection of primary colorectal cancer and pulmonary metastasectomy using minimal invasive surgery is safe and might lead to both a decrease in costs and benefit to patients. This simultaneous approach could therefore be considered as an alternative for a two-stage approach in properly selected patients. However, these results should be validated in a larger series.
