Perioperative Outcomes of Thoracoscopic Reoperations for Clinical Recurrence of Pulmonary Malignancy

The utility of thoracoscopic lung surgery is well established, however, reoperation for pulmonary resections has not been thoroughly studied. We sought to evaluate patient perioperative outcomes following redo thoracoscopic pulmonary resections for malignancy by comparing first and second ipsilateral operations. We included patients undergoing redo thoracoscopic pulmonary resections for clinically recurrent disease following prior lung resection for malignancy from January 1, 2011 to May 31, 2019. Nonmalignant indications were excluded. We analyzed type of procedure, diagnosis, rate of conversion to open, estimated blood loss, operating time, margin status, length of stay and complications. Forty-one patients met our inclusion criteria. The median age was 68 years (range 13-84) and 20 were women. Redo operations had longer lengths of stay with a trend toward higher rate of conversion to thoracotomy, but other perioperative outcomes were similar. No difference in outcomes was seen when patients were grouped by indication for reoperation (recurrence, multiple primaries, and metastasis) or approach of first operation (VATS vs open). However, patients undergoing an anatomic resection after a prior anatomic resection had more complications, higher blood loss, higher rate of conversions to thoracotomy, significantly longer length of stay and longer operative times than nonanatomic resections. Thoracoscopic reoperation for recurrent, metachronous, or metastatic cancer to the lung is a reasonable approach. However, the surgeon must recognize and counsel patients that in patients undergoing a redo anatomic resection, thoracoscopic reoperations are more difficult with more adverse outcomes.
