A: No, the lungs can't regenerate. You can take out 75% to 80% of the liver and it will regenerate, but not the lungs. After a lobectomy, your mediastinum (a space in the thorax in the middle of the chest) and diaphragm will shift a little, so there won't be a space left where the lobe was taken out.
As described above, the lung has the capacity to regenerate, especially the lung epithelium, a process that is dependent on the survival of suitable progenitor cells located within a viable distance of the damage site.
Recent studies have shown that the respiratory system has an extensive ability to respond to injury and regenerate lost or damaged cells. The unperturbed adult lung is remarkably quiescent, but after insult or injury progenitor populations can be activated or remaining cells can re-enter the cell cycle.
There are three lobes on the right lung and two on the left lung. You can survive without all of the lobes, and in some cases, you can survive with only one lung. Lung removal surgeries may involve removal of part of one or more lobes, or all of one to three lobes.
Most people can get by with only one lung instead of two, if needed. Usually, one lung can provide enough oxygen and remove enough carbon dioxide, unless the other lung is damaged.
After the surgery, your body adjusts to make up for the missing section. The remaining healthy lung tissue expands to fill the space and the other lung may shift toward the side of the removed lobe.
In patients with early-stage non–small cell lung cancer (NSCLC), lobectomy achieves the best long-term survival. Yet, successful operations for stages I and II lung cancer are associated with a 5-year survival of only 40% to 70%. Thus, treatment is often palliative rather than curative.
Despite the limited number of patients in our series, we believe that a second lung lobectomy is a feasible technique, with zero mortality but with significant morbidity.
Resection of the upper lobe of left lung is the most difficult procedure in lobectomy. The vessels in this area have multiple branches and variations.
It is common to feel tired for 6 to 8 weeks after surgery. Your chest may hurt and be swollen for up to 6 weeks. It may ache or feel stiff for up to 3 months. For up to 3 months, you may also feel tightness, itching, numbness, or tingling around the cut (incision) the doctor made.
Normally lungs have the ability to repair and regenerate as they are constantly exposed to pollution and microbes from the external environment. The next phase in this research would be to determine whether harnessing the Hippo pathway can help promote the lung's natural ability to regenerate after injury.
Your lungs are self-cleaning, which means they will gradually heal and regenerate on their own after you quit smoking. However, there are certain lifestyle behaviors you can practice to try and accelerate the rate at which your lungs heal.
In general, you may be able to return to work without required lifting around two weeks from discharge. You should take four weeks to recover for jobs that require lifting or after a thoracotomy.
Your lungs are a remarkable organ system that, in some instances, have the ability to repair themselves over time. After quitting smoking, your lungs begin to slowly heal and regenerate. The speed at which they heal all depends on how long you smoked and how much damage is present.
Each resection of lung tissue leads to a decrease in lung function and according to our study in pulmectomy up to 44%, and lobectomy and up to 22% compared to preoperative values which should be taken into account in preoperative assessment.
Scientists at the University of Texas Medical Branch in Galveston have succeeded in growing human lungs in the laboratory, using components from the lungs of deceased children.
Brunelli and colleagues found in their series that 90-day mortality was not much higher than 30-day mortality after VATS lobectomy. In hospital/30-day mortality rate was 1.9%.
Objective: Lobectomy is a standard treatment for stage I non-small cell lung cancer, but a significant proportion of patients are considered at high risk for complications, including mortality, after lobectomy and might not be candidates. Identifying who is at risk is important and in evolution.
The risks of this procedure may include: Infection. Air in the space between the lung covering (pleural space) that causes the lung to collapse (pneumothorax) Bleeding.
Having a lobe removed is a very painful process that requires one to be very patient about the time it takes to recover. From the surgery to the months during recovery, I was given various forms of pain relief that never got rid of the pain but certainly helped get me through the process.
The very good long term results are presented including the 10-year and 20-year survival rate. Two patients are still alive after 30 and 34 years respectively. One patient is alive 29 years after a lobectomy and 13 years after a contralateral lobectomy for a new primary cancer.
These data show that lung volume can be completely recovered after lobectomy for congenital lobar emphysema in infancy. The volume increase occurs on the operated side, and probably represents tissue growth rather than simple distension.
While many people regard lung cancer surgery as a means to "cut out the cancer," one of the primary aims of the surgery is to restore or improve the quality of life. And, despite what some may think, people can live normal, active lives even when part or all of a lung is removed.
