Lung segmental resection is arguably safer than lung wedge resection because it has a lower probability of postoperative recurrence.
Lung segmentectomy is an operation that removes an entire lung segment, each of which has separate blood vessels and bronchial tubes. Lung segmentectomy removes an entire complete and independent unit, and therefore has a smaller postoperative recurrence rate; whereas lung wedge resection removes only a wedge-shaped area around the lesion, and although wedge resection removes a smaller area than segmentectomy, it has a higher postoperative recurrence rate.
Since segmental resection has a smaller postoperative recurrence rate than pulmonary wedge resection, it is safer. However, segmental lung resections are generally more difficult to perform, and lung wedge resections are generally only indicated for smaller lesions located peripherally, whereas segmental lung resections can be indicated for lesions located closer to the center.
If lung resection is required, follow your doctor’s instructions.
