What is a likely benefit of sparing lung tissue during resection?

• A. Improved postoperative pulmonary function
• B. Increased recurrence
• C. Longer hospital stay
• D. Higher complication rate

Answer: (A)

Preserving lung tissue during resection keeps more functional lung units intact, which directly supports better postoperative lung function. When less parenchyma is removed, there is more surface area for gas exchange and maintained chest wall mechanics, helping maintain vital capacity and diffusion after surgery. That translates into improved spirometry results, less postoperative dyspnea, and a smoother recovery. The other outcomes aren’t benefits of sparing tissue: sparing tissue does not inherently increase cancer recurrence and, while hospital stay and complication rates depend on many factors, preserving lung parenchyma is aimed at maintaining function and improving recovery rather than worsening outcomes.
