A wedge resection of the lung is called a wedge resection in which the lung is cut at an angle like a cake. Usually the lung tissue is removed without growing back, but the effect of the resection on lung function also depends on the size of the resection. After wedge resection of the lung, there may be a portion of the cavity. This cavity may be filled by the remaining lung expansion or by the surrounding organs, such as the thorax collapsing downward or the mediastinum moving downward and the diaphragm lifting upward, but the organ damage will not regenerate. Of course some patients say that the stomach can be operated on the stomach can be large due to the volume of the stomach after the patient has eaten, the volume of the lungs generally will not be larger, but only compensatory with the original about the same, that is, the area is large, about the same, but not regrowth. So the patient has lung surgery, the lung tissue shrinkage and reduction are normal and will not affect the overall lung function. Pulmonary wedge resection, because the resection area is relatively small, so generally will not have much impact on lung function, sometimes the patient appears wheezing, a little suffocating, mainly because of psychological factors.
