Repeat pulmonary resection for lung malignancies does not affect the postoperative complications: a retrospective...

Area of Science:

• Thoracic Surgery
• Surgical Oncology
• Pulmonary Medicine

Background:

• Repeat pulmonary resection (RPR) is performed for multiple lung cancers, including non-small cell lung cancer and metastatic lung tumors.
• While prognostic benefits are reported, the risks associated with RPR require thorough analysis.

Purpose of the Study:

• To analyze the risks and postoperative complications associated with repeat pulmonary resection (RPR).
• To identify factors influencing postoperative complications in patients undergoing RPR.

Main Methods:

• Analysis of 41 patients who underwent complete resection for lung malignancies between 2010 and 2019.
• Evaluation of the relationship between postoperative complications (Clavien-Dindo classification) and preoperative/perioperative factors.
• Comparison of complication rates between ipsilateral and contralateral RPR.

Main Results:

• The overall postoperative complication rate was 29% for both the first and second operations.
• No significant factors for increased complications were found in multivariate analysis, though longer operation times (>2 hours) at the second operation showed a trend towards increased complications.
• Operation time was significantly longer in the ipsilateral group compared to the contralateral group, with a trend towards longer wound length.

Conclusions:

• Repeat pulmonary resection (RPR) is a safe and feasible procedure.
• RPR is not associated with an increased rate of postoperative complications, even when performed on the ipsilateral side.
