Unsuccessful Open thoracotomy too remove left lower lung lobe - 1265387

The surgeon was unable to respect the bottom right lung for the top one saying that it was like cutting through concrete. However he was able to respect to bottom lobe for the diaphragm and perform talc poudre to prevent re-fusion.
Bottom line, the surgery was unsuccessful and my brother died six months late after refusing chemo therapy.

What the surgeon did not make clear...why were the two lobes cemented as to be unresected for one another

Sincerely, glenglne
