Lung cancer can be classified into two main types: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC, the most common of the two types, is a group of cancers including squamous cell carcinoma, adenocarcinoma and large cell carcinoma.{{Cite web |date=2011-02-02 |title=Non-small cell lung cancer |url=https://www.cancer.gov/publications/dictionaries/cancer-terms/def/non-small-cell-lung-cancer |access-date=2023-04-09 |website=www.cancer.gov |language=en}} SCLC is highly aggressive and consists of small ovoid cells.{{Cite web |title=Small Cell Lung Carcinoma - MeSH - NCBI |url=https://www.ncbi.nlm.nih.gov/mesh/?term=%22Carcinoma,+Small-Cell+Lung%22%5BMeSH+Terms%5D |access-date=2023-04-09 |website=www.ncbi.nlm.nih.gov}} Surgical resection is used curatively in stage I-III NSCLC and palliatively in stage IV.{{Cite book |url=https://www.worldcat.org/oclc/1119743695 |title=Sugarbaker's adult chest surgery |date=2020 |others=David J Sugarbaker |isbn=978-1-260-02694-8 |edition=3rd |location=New York |oclc=1119743695}}

A pneumothorax, also known as a collapsed lung, is a collection of air outside the lung in the pleural cavity. Depending on etiology, a pneumothorax is classified as spontaneous, traumatic and iatrogenic. A spontaneous pneumothorax is further classified as primary and secondary, with the former occurring in individuals with no clinical lung disease and the latter occurring as a complication of preexisting lung disease.{{Cite journal |last1=Sahn |first1=Steven A. |last2=Heffner |first2=John E. |date=2000-03-23 |title=Spontaneous Pneumothorax |url=http://www.nejm.org/doi/abs/10.1056/NEJM200003233421207 |journal=New England Journal of Medicine |language=en |volume=342 |issue=12 |pages=868–874 |doi=10.1056/NEJM200003233421207 |pmid=10727592 |issn=0028-4793}}

Chronic obstructive pulmonary disease (COPD) is a group of diseases that results in airflow blockage and therefore cause breathing-related issues. COPD includes emphysema as well as chronic bronchitis.{{Cite web |date=2023-03-20 |title=Chronic Obstructive Pulmonary Disease (COPD) {{!}} CDC |url=https://www.cdc.gov/copd/index.html |access-date=2023-03-28 |website=www.cdc.gov |language=en-us}}

Cystic fibrosis is a genetic disease, caused by a mutation that results in defects in movement of salt and water in and out of cells which can cause sticky mucus in the body’s tubes and passageways such as in the lungs.{{Cite web |date=2017-10-23 |title=Cystic fibrosis |url=https://www.nhs.uk/conditions/cystic-fibrosis/ |access-date=2023-03-28 |website=nhs.uk |language=en}}

Pulmonary hypertension occurs as a result of excess pressure in the blood vessels from the heart to the lungs. An increased amount of muscle in the walls of the blood vessels to the lung is prominent in cases with pulmonary hypertension. Although there are treatments such as oxygen therapy and medicine that is given to reduce swelling, lung transplantation may be necessary in some extreme cases.{{Cite web |last=CDC |date=2019-12-03 |title=Pulmonary Hypertension {{!}} cdc.gov |url=https://www.cdc.gov/heartdisease/pulmonary_hypertension.htm |access-date=2023-04-09 |website=Centers for Disease Control and Prevention |language=en-us}}

Idiopathic pulmonary fibrosis causes the lungs to become scarred which results in a difficulty in breathing. The causes are of this disease is still not fully known, however, prevention methods include self-care such as stopping smoking and exercising. Medicines such as pirfenidone and nintedanib are also commonly used in order to reduce the rate of scarring in the lungs. Lung transplantation is effective in certain cases, however this depends on the availability of healthy donor lungs.{{Cite web |date=2017-10-23 |title=Idiopathic pulmonary fibrosis |url=https://www.nhs.uk/conditions/idiopathic-pulmonary-fibrosis/ |access-date=2023-03-28 |website=nhs.uk |language=en}}

Anatomic resections refer to procedures where a section of the lung is removed with respect to lobar or segmental anatomy.{{Citation |title=3 Minute Papers: Lobectomy vs Segmentectomy for Lung Cancer | date=26 May 2022 |url=https://www.youtube.com/watch?v=qMb0km2twtk |access-date=2023-03-28 |language=en}} These include pneumonectomies, lobectomies and segmentectomies and are commonly used for the treatment of NSCLC. Preoperative evaluations for resections include cancer staging via a chest CT scan and PET scan, followed by assessments of pulmonary reserve volume and cardiac function to determine the amount of lung tissue that can be safely removed without developing pulmonary insufficiency.{{Cite book |url=https://www.worldcat.org/oclc/793914018 |title=Fischer's mastery of surgery |date=2011 |publisher=Wolters Kluwer Health/Lippincott Williams & Wilkins |others=Josef E.

A pneumonectomy is the surgical removal of an entire lung. Due to the high morbidity and mortality of the procedure, its viability for treating lung cancer is a subject of debate.{{Cite journal |last1=Gu |first1=Chang |last2=Wang |first2=Rui |last3=Pan |first3=Xufeng |last4=Huang |first4=Qingyuan |last5=Luo |first5=Jizhuang |last6=Zheng |first6=Jiajie |last7=Wang |first7=Yiyang |last8=Shi |first8=Jianxin |last9=Chen |first9=Haiquan |date=2017-07-05 |title=Comprehensive study of prognostic risk factors of patients underwent pneumonectomy |url=https://www.jcancer.org/v08p2097.htm |journal=Journal of Cancer |language=en |volume=8 |issue=11 |pages=2097–2103 |doi=10.7150/jca.19454 |issn=1837-9664 |pmc=5559972 |pmid=28819411}} However, pneumonectomies are still used for lung carcinomas that are large and centrally located or have invaded the interlobar fissures. Another indication for the use this procedure is lung destruction due to chronic infections.

During a pneumonectomy, the pleural cavity is accessed through a thoracotomy. With direct access to the tumour, the need for pneumonectomy is reassessed. After surgeons decide to proceed with the procedure, the hilar structures are dissected sequentially. The pulmonary artery, then the pulmonary veins, are divided via stapling. Next, the main bronchus is divided using a scalpel and the lung is removed from the pleural cavity. The bronchial stump is subsequently closed by polyglactin sutures. Finally, mediastinal lymph nodes are dissected.

A lobectomy is the surgical removal of one of the five lung lobes (right upper, right middle, right lower, left upper and left lower lobes).{{Cite web |last=American Lung Association |title=Lobectomy |url=https://www.lung.org/lung-health-diseases/lung-procedures-and-tests/lobectomy |access-date=2023-03-28 |website=www.lung.org |language=en}} Lobectomies are the most common type of lung surgery and the standard operation for most NSCLC patients.{{Cite journal |last1=Bendixen |first1=Morten |last2=Jørgensen |first2=Ole Dan |last3=Kronborg |first3=Christian |last4=Andersen |first4=Claus |last5=Licht |first5=Peter Bjørn |date=2016-06-01 |title=Postoperative pain and quality of life after lobectomy via video-assisted thoracoscopic surgery or anterolateral thoracotomy for early stage lung cancer: a randomised controlled trial |url=https://www.thelancet.com/journals/lanonc/article/PIIS1470-2045(16)00173-X/fulltext |journal=The Lancet Oncology |language=English |volume=17 |issue=6 |pages=836–844 |doi=10.1016/S1470-2045(16)00173-X |issn=1470-2045 |pmid=27160473}} Though specific surgical techniques vary for each lobe, the general workflow is identical. The lobe to be resected is first visualized through thoracotomy or thoracoscopy. Next, the surrounding lymph nodes are harvested to check for metastasis. After confirmation that no metastasis has taken place, the vasculature of the lobe is controlled by blood vessel division using a stapler. Stapling is also used to divide the lobar bronchus and subsequently separate the lobe along the lung fissure(s). After the lobe is removed, lymph node dissection is completed.

Specific considerations exist for certain lobes. Right middle lobectomies are not usually carried out alone and are instead part of a bilobectomy alongside a right upper or lower lobectomy. Left upper lobectomies require additional caution to avoid arterial branches from the fissure and proximal pulmonary artery. Another risk is the proximity of the recurrent laryngeal nerve to the upper mediastinal lymph nodes, which increases its risk of injury during lymph node dissection.{{Cite journal |last1=Chai |first1=Young Jun |last2=Lee |first2=Jung-Man |last3=Seong |first3=Yong Won |last4=Moon |first4=Hyeon Jong |date=2020-03-13 |title=Application of Continuous Intraoperative Neuromonitoring During VATS Lobectomy for Left Lung Cancer to Prevent Recurrent Laryngeal Nerve Injury |journal=Scientific Reports |language=en |volume=10 |issue=1 |pages=4636 |doi=10.1038/s41598-020-61500-6 |issn=2045-2322 |pmc=7069963 |pmid=32170087|bibcode=2020NatSR..10.4636C }} Thus, a swallowing study is required if nerve damage is suspected postoperatively.

A sleeve lobectomy is a lobectomy that is coupled with the removal of a part of the main bronchus. The ends of the bronchus are then rejoined to reattach any remaining lung lobes.{{Cite web |date=2011-02-02 |title=Sleeve lobectomy |url=https://www.cancer.gov/publications/dictionaries/cancer-terms/def/sleeve-lobectomy |access-date=2023-04-12 |website=www.cancer.gov |language=en}} This procedure is performed in lieu of pneumonectomy when surgeons determine the removal of the entire lung to be unnecessary for centrally located tumours.

Segmentectomies are the surgical removal of bronchopulmonary segments and often involve the removal of two adjacent segments. The pulmonary arterial branches to the segments are first identified then divided. Next, stapling is used to divide the segmental bronchi and separate the segments from the lung. Compared to lobectomies, this procedure has higher survivability for stage 1A patients with tumours ≤ 2 cm in diameter.{{Cite journal |last1=Saji |first1=Hisashi |last2=Okada |first2=Morihito |last3=Tsuboi |first3=Masahiro |last4=Nakajima |first4=Ryu |last5=Suzuki |first5=Kenji |last6=Aokage |first6=Keiju |last7=Aoki |first7=Tadashi |last8=Okami |first8=Jiro |last9=Yoshino |first9=Ichiro |last10=Ito |first10=Hiroyuki |last11=Okumura |first11=Norihito |last12=Yamaguchi |first12=Masafumi |last13=Ikeda |first13=Norihiko |last14=Wakabayashi |first14=Masashi |last15=Nakamura |first15=Kenichi |date=2022-04-23 |title=Segmentectomy versus lobectomy in small-sized peripheral non-small-cell lung cancer (JCOG0802/WJOG4607L): a multicentre, open-label, phase 3, randomised, controlled, non-inferiority trial |url=https://pubmed.ncbi.nlm.nih.gov/35461558/ |journal=Lancet |volume=399 |issue=10335 |pages=1607–1617 |doi=10.1016/S0140-6736(21)02333-3 |issn=1474-547X |pmid=35461558|s2cid=248303647 }}

Non-anatomic resections refer to the removal of lung tissue without respect to lobar or segmental anatomy. They can be used to treat a variety of lung diseases such as NSCLC and tuberculosis.

A wedge resection is the non-anatomic removal of a triangular-shaped piece of tissue from the lungs. The utility of wedge resection in NSCLC is disputed. Wedge resection is currently used in NSCLC patients with low pulmonary function, or for pulmonary tuberculosis patients with multiple lesions which do not respect intersegmental boundaries.

A bleb resection is the surgical removal of one or more blebs, small collections of air between the lung and visceral pleura. Blebs may combine to form larger cysts named bullae. The rupture of blebs or bullae results in air leaking into the pleural space, causing a spontaneous pneumothorax. In most cases, patients will be unaware of blebs until they are detected by CT scans or cause noticeable symptoms such as chest pain.{{Cite web |title=Lung Blebs: Causes, Risks, and Treatment Options - Ezra |url=https://ezra.com/blog/what-is-a-lung-bleb |access-date=2023-03-28 |website=ezra.com |language=en}}

Bleb resections may be done via mini-thoracotomy or thoracoscopy. After inspection of the chest cavity, identified blebs are removed via dissection and stapling. To prevent future bleb formation, this procedure is often accompanied by pleurodesis.{{Cite book |last=LoCicero |first=Joseph |url=https://www.worldcat.org/oclc/1109787261 |title=Shields' General Thoracic Surgery |date=2018 |publisher=Wolters Kluwer |isbn=978-1-4963-7231-4 |edition=8th |location=Philadelphia |oclc=1109787261}}

A pneumothorax is commonly treated with needle aspiration of air followed by chest tube drainage. In the case of a recurrent pneumothorax, pleurodesis may be used to prevent further air accumulation.{{Citation |last1=McKnight |first1=Catherine L. |title=Pneumothorax |date=2023 |url=http://www.ncbi.nlm.nih.gov/books/NBK441885/ |work=StatPearls |access-date=2023-03-28 |place=Treasure Island (FL) |publisher=StatPearls Publishing |pmid=28722915 |last2=Burns |first2=Bracken}}

Pleurodesis is the obliteration of the pleural space, achieved by adhering the visceral pleura on the lung surface to the costal pleura of the chest wall. Adhesion is caused by inflammation and subsequent scarring of the pleural layers. Inflammation may be induced by either physical or chemical irritation. The former is commonly used in younger patients and involves surgical abrasion. The latter involves the instillation of chemical sclerosant, usually sterile talc, via a chest tube. Other sclerosing agents include tetracycline and bleomycin. After sclerosant instillation, the patient may be moved through various positions to ensure even distribution. Due to the pain of this operation, it is accompanied by local anaesthesia. Pleurodesis is also used in recurrent pleural effusion, a common result of lung cancer.{{Cite book |url=https://www.worldcat.org/oclc/795352247 |title=Oxford handbook of respiratory medicine |date=2009 |publisher=Oxford University Press |others=Stephen Chapman, Inc Ovid Technologies |isbn=978-0-19-156275-4 |edition=2nd |location=New York |oclc=795352247}}

Lung transplant is defined as ‘an operation to remove and replace a diseased lung with a healthy human lung from a donor. A donor is most commonly known to be a deceased person, however, in very rare cases a section of the lung that is required for a patient can be transplanted from a living donor. Lung transplants are usually required when a patient has advanced lung disease whereby the disease is also unresponsive to other methods of treatment. Another significant reason for a lung transplant to be considered as a necessary option is if the patients’ life expectancy is predicted to be under three years without the lung transplant procedure taking place. Typical conditions that are treated with a lung transplant include COPD, cystic fibrosis, pulmonary hypertension and idiopathic pulmonary fibrosis.{{Cite web |date=2018-10-03 |title=Lung transplant |url=https://www.nhs.uk/conditions/lung-transplant/ |access-date=2023-03-28 |website=nhs.uk |language=en}}

Methods for the preservation of donor lungs are imperative in order to increase availability of lungs for transplantation which therefore increases the efficacy of the treatment as more available lungs for transplantation leads to more people being applicable to undergo the treatment/transplantation. Before an organ is removed from the donor for transplantation, the donor organ is commonly flushed free of blood with a preservation solution that is prepared to be ice-cold which also contains essential elements such as electrolytes and nutrients. Furthermore, when the organ is removed from the donor, it is packaged in wet ice for preservation of the organ.{{Cite web |title=Organ Transplantation Process |url=https://www.nyp.org/transplant/organ-donation/organ-transplant-process |access-date=2023-03-28 |website=NewYork-Presbyterian |language=en}} A therapy called ex-vivo lung perfusion that is commonly used for the donor lung just before transplantation provides an enhancement of the quality of the organ and can potentially make previously unsuitable organs, safe for transplantation.{{Cite web |title=Ex Vivo Lung Perfusion (EVLP) |url=https://www.pennmedicine.org/for-patients-and-visitors/find-a-program-or-service/transplant-institute/lung-transplant/lung-transplant-process/ex-vivo-lung-perfusion#:~:text=Ex%20vivo%20lung%20perfusion%20(EVLP)%20is%20an%20innovative%20therapy%20applied,previously%20unsuitable%20safe%20for%20transplant |access-date=2023-03-28 |website=www.pennmedicine.org}}

A pneumonectomy comes with its own risks whereby the most common complications are cardiac arrhythmia as well as atrial fibrillation (or flutter), which commonly occurs in the first three days following the surgery. Furthermore, additional risks following this surgery include: cardiac herniation, pulmonary complications (e.g. pneumonia), bronchopleural fistula, pulmonary oedema, multi-organ dysfunction, acute lung injury, acute respiratory distress syndrome (ARDS) and postoperative acute kidney injury.{{Citation |last1=Beshara |first1=Michael |title=Pneumonectomy |date=2023 |url=http://www.ncbi.nlm.nih.gov/books/NBK555969/ |work=StatPearls |access-date=2023-04-13 |place=Treasure Island (FL) |publisher=StatPearls Publishing |pmid=32310429 |last2=Bora |first2=Vaibhav}}

Lobectomies share many of the complications that come with a pneumonectomy.

Similar to other anatomic resections, cardiac arrhythmia is a major complication for segmentectomy. Additionally, hemorrhage in the pleural cavity may occur due to injury to the pulmonary artery or its branches. Patients may also develop a contralateral pneumothorax, necessitating the placement of a chest tube to eliminate air within the pleural cavity.{{Cite web |title=Lung Segmentectomy and Limited Pulmonary Resection Technique: Segmentectomy, Lesser Lung Resection (Wedge Resection), Complications |url=https://emedicine.medscape.com/article/1894257-technique |access-date=2023-04-12 |website=emedicine.medscape.com |language=en}}

Lung surgeries can be perceived as invasive procedures that may cause side effects such as bruising, swelling, numbness, pain, scarring and infection. However, new methods such as video-assisted thoracoscopic surgery (VATS) provide a minimally invasive method which can eliminate diseased parts of the lungs and lymph nodes. A development of thoracoscopy, VATS utilizes small, high-resolution cameras which are inserted into the chest through small incisions. This grants surgeons a high degree of visibility into the pleural cavity despite making smaller incisions, resulting in quicker patient recovery.{{Cite journal |last1=Lim |first1=Eric |last2=Batchelor |first2=Tim J.P. |last3=Dunning |first3=Joel |last4=Shackcloth |first4=Michael |last5=Anikin |first5=Vladimir |last6=Naidu |first6=Babu |last7=Belcher |first7=Elizabeth |last8=Loubani |first8=Mahmoud |last9=Zamvar |first9=Vipin |last10=Harris |first10=Rosie A. |last11=Dabner |first11=Lucy |last12=McKeon |first12=Holly E. |last13=Paramasivan |first13=Sangeetha |last14=Realpe |first14=Alba |last15=Elliott |first15=Daisy |date=2022-02-22 |title=Video-Assisted Thoracoscopic or Open Lobectomy in Early-Stage Lung Cancer |url=https://evidence.nejm.org/doi/10.1056/EVIDoa2100016 |journal=NEJM Evidence |language=en |volume=1 |issue=3 |pages=EVIDoa2100016 |doi=10.1056/EVIDoa2100016 |pmid=38319202 |s2cid=246049827 |issn=2766-5526}}

Moreover, treatment for lung cancer has been further developed with the use of robotic surgery as a method for treatment. This method involves the use of robotic arms which are manipulated by a surgeon at a console, enabling more precise movements and providing the surgeon with 3D vision of the surgical site.{{Citation |last=Szegedi |first=Laszlo L. |title=Chapter 52 - Robotic Thoracic Surgery |date=2022-01-01 |url=https://www.sciencedirect.com/science/article/pii/B9780323713016000524 |work=Cohen's Comprehensive Thoracic Anesthesia |pages=757–765 |editor-last=Cohen |editor-first=Edmond |access-date=2023-04-10 |place=Philadelphia |publisher=Elsevier |language=en |doi=10.1016/b978-0-323-71301-6.00052-4 |isbn=978-0-323-71301-6|s2cid=240009708 }} Similar to VATS, robotic surgery has also been found to be minimally invasive and is extremely useful for removing certain parts of lung tissue that are diseased as well as surrounding lymph nodes.{{Cite web |last=Association |first=American Lung |title=Robotic Thoracic Surgery |url=https://www.lung.org/lung-health-diseases/lung-procedures-and-tests/robotic-thoracic-surgery |access-date=2023-03-28 |website=www.lung.org |language=en}} However, comparisons of current robotic methods with VATS have shown no significant differences in patient outcome.{{Cite journal |last1=Agzarian |first1=John |last2=Fahim |first2=Christine |last3=Shargall |first3=Yaron |last4=Yasufuku |first4=Kazuhiro |last5=Waddell |first5=Thomas K. |last6=Hanna |first6=Waël C. |date=2016-03-01 |title=The Use of Robotic-Assisted Thoracic Surgery for Lung Resection: A Comprehensive Systematic Review |url=https://www.semthorcardiovascsurg.com/article/S1043-0679(16)00018-6/fulltext |journal=Seminars in Thoracic and Cardiovascular Surgery |language=English |volume=28 |issue=1 |pages=182–192 |doi=10.1053/j.semtcvs.2016.01.004 |issn=1043-0679 |pmid=27568159}}
