Background Both robotic pulmonary operations and anatomic segmentectomy are being increasingly performed. The largest published series of anatomic robotic segmentectomy comprises 35 patients, and the specific details of port placement are poorly understood. Methods This is a review of a consecutive series of patients from a single surgeon's prospective database. All patients in the study were scheduled to undergo robotic anatomic segmentectomy. Results Between February 2010 and December 2014, 100 patients went to the operating room for a planned pulmonary segmentectomy. A robotic approach was chosen for all. Seven patients underwent conversion to robotic lobectomy, and the remaining 93 patients had an anatomic robotic segmentectomy. There were no conversions to thoracotomy. Indications for resection were lung cancer in 79 patients, metastatic lesions in 10 patients, fungal infections in 4 patients, and other conditions in 7 patients. The median age was 69 years, and 50 patients were men. The median blood loss was 20 mL (range, 10-120 mL), the median number of lymph nodes removed was 19, the median operative time was 1.28 hours (88 minutes), the median length of stay was 3 days, and major morbidity occurred in 2 patients (pneumonia in both). All had undergone R0 resection. There were no 30- or 90-day mortalities. Of the 79 patients with lung cancer, the median follow-up was 30 months, and 3 patients (3.4%) had recurrence in the operated lobe. Overall survival was 95% at 30 months. Conclusions Completely portal robotic anatomic segmentectomy is safe and effective and offers outstanding intraoperative 30-day and 90-day results. The recurrence rate is approximately 3% at 2.5 years.
