BACKGROUND: Patients who underwent lobectomy resection are prone to hypoxemia, and the vast majority present with type I respiratory failure. Thus, improvement of hypoxemia is one of the most important factors to facilitate postoperative recovery of patients. In this study, the superiority-inferiority of different oxygen inhalation methods were compared with high-flow nasal oxygen therapy (HFNO), noninvasive mechanical ventilation (NIMV) and nasal oxygen breath (NOB) in patients with hypoxemia after single-port video-assisted thoracoscopic (VATS) lobectomy, and the clinical efficacy of HFNO in these patients was further investigated. METHODS: A total of 180 patients from the Second Affiliated Hospital of Soochow University in China with hypoxemia who accepting single-port VATS lobectomy from June 2021 to March 2022 were randomly divided into three groups (n=60), which were treated with HFNO, NIMV and NOB, respectively. The results of arterial blood gas analysis, patient's comfort score and incidence of complications were observed before, 1 h, 6 h-12 h and after use. Statistical analyses were conducted using statistical program for social sciences 25.0 (SPSS 25.0), and P<0.05 was considered as statistical significance. RESULTS: For patients with hypoxemia after accepting single-port VATS lobectomy, HFNO was no less effective than NIMV (P=0.333), and both of whom could fast increase patients' partial pressure of oxygen/fraction of inspiration O₂ (PaO₂/FiO₂) compared to NOB (P<0.001). Besides, HFNO shows a great advantage in comfort degree and stay length (P<0.001, P=0.004), and incidence of complications were slightly lower than other groups (P=0.232). But it is worthy to note that HFNO is still slightly less effective than NIMV in patients with postoperative hypoxemia accompanied by elevated partial pressure of carbon dioxide (PaCO₂). CONCLUSIONS For patients with hypoxemia who accepting single-port VATS lobectomy, HFNO can be used as the first choice. However, for patients with postoperative hypoxemia accompanied by elevated PaCO₂, NIMV is still recommended to improve oxygenation.

Lung volume reduction loop uses bronchoscopic lung volume reduction(BLVR) technology to compress and collapse the necrotic emphysema tissue and exhaust the internal gas to achieve the purpose of lung volume reduction to treat emphysema. After the lung volume reduction loop is implanted into the human body, the compressed part of the lung tissue tends to expand with breathing, which makes the lung volume reduction loop expand into a linear trend periodically. Fatigue resistance is one of the most important performance indexes of the lung volume reduction loop. In the paper, Z-direction vibration fatigue machine was used to simulate the changes of human respiratory cycle movement to test the fatigue performance of lung volume reduction loop, which can provide some reference for the test method of in vitro fatigue performance of lung volume reduction related products in the future.

In recent years, the incidence and detection rate of lung cancer have gradually increased, and segmentectomy has been increasingly used to treat early non-small cell lung cancer. Some scholars believe that segmentectomy is more conducive to the preservation of postoperative lung function than lobectomy. Some studies have found that the two surgical methods have little difference in postoperative cost retention. This article deals with segmentectomy and lobectomy. A review of related studies on postoperative pulmonary function changes.

OBJECTIVETo investigate the operation of lung transplantation for end-stage emphysema.

METHODSFrom September 2002 to February 2005, 9 patients with chronic obstructive pulmonary disease (COPD) underwent lung transplantation. The types of surgery included single lung transplantation in 2 patients, lung transplantation with asynchronous contralateral lung volume reduction (one week later) in 1, single lung transplantation with synchronized contralateral lung volume reduction in 4, and bilateral sequential lung transplantation without cardiopulmonary bypass in 2.

RESULTSThe volume of chest drainage was more than 2000 ml at the first postoperative day in 2 patients, one was reoperated for hemostasis and another was successfully responded to conservative therapy. The ventilation time was ranged from 3 to 22 days postoperatively. Two patients were received tracheotomy. Seven patients achieved good results, two of them had returned to work, and 1 patient had lived for 30 months. One patient was died of severe acute rejection (4A) at 15th postoperative day and 1 succumbed to multisystem organ failure due to severe bacterial infection combine fungal infection.

CONCLUSIONEnd-stage emphysema is an indication for single lung transplantation. Single lung transplantation with contralateral lung volume reduction is a good way to utilize donor. If patient suffered from infection, double-lung transplantation should be considered first.

BACKGROUND AND OBJECTIVEVideo-assisted thoracoscopic surgery (VATS) has been widely used in the diagnosis and treatment of chest diseases. The aim of this study was to explore the feasibility and clinical value of lobectomy with single utility port complete VATS.

METHODSFrom September 2009 to December 2009, 21 cases underwent lobectomy with single utility port complete VATS. Of 21 patients, right upper lobectomy was 12 cases, left lower lobectomy 5 cases, right lower lobectomy 2 cases, left upper lobectomy 1 case, right middle lobectomy 1 case.

RESULTSThe operation process were smooth in all patients and without conversion to thoracotomy. The mean operative time was (132.7 +/- 16.2) min and the mean intraoperative blood loss was (110.5 +/- 24.6) mL. The average chest tube drainage time was (3.1 +/- 1.3) d, and the mean hospitalization day was (5.2 +/- 3.2) d. All patients recovered smoothly and without severe complications. There were no post-operative deaths.

CONCLUSIONLobectomy with single utility port VATS is technically feasible and has the advantages of minimal invasive and rapid recovery.

A 20 year-old woman was admitted to our clinic complaining of dyspnea, cough, chest pain and pleural effusion. The diagnosis of pulmonary hydatid cyst was made on the basis of parasitology laboratory findings, computed tomographic results and chest radiographic findings. A giant pulmonary hydatid cyst (33x14x12 cm) was located in the left lower lobe, which involved more than 90% of the lobe. The patient was treated surgically using cystotomy and capitonnage. This is a case of a giant pulmonary hydatid cyst published in the literature, which was surgically treated without a lobectomy, by preserving the lung parenchyma.
