BACKGROUND: China is a high-incidence area of lung cancer, and its morbidity and mortality were the highest in malignant tumors. At present, the popularization of low-dose computed tomography (CT) examination has significantly improved the detection rate of early lung cancer, anatomical segmentectomy is currently widely used early in non-small cell lung cancer (NSCLC) and those who cannot tolerate lobectomy in patients with lung cancer. However, the anatomical structure of segment and its surgical operation is relatively complex, lead to segmentectomy has a high risk and difficulty...

A wild-caught, research-naïve, adult male mustached tamarin (Saguinus mystax) experienced sudden onset of bilateral hindlimb paresis. Physical examination established the presence of paralysis and the lack of femoral pulses and deep pain in both legs. There were no signs of external trauma and, due to a poor prognosis, euthanasia was elected. Necropsy findings included pleural effusion, partial pulmonary atelectasis and congestion, dilatatory cardiomyopathy, a renal hemorrhagic infarct, and a thromboembolus located at the trifurcation of the distal abdominal aorta...

BACKGROUND: Predicted postoperative FEV1 (ppoFEV1) must be estimated preoperatively prior to surgery for non-small cell lung cancer (NSCLC). We evaluated a lung volumetry approach based on chest computed tomography (CT). METHODS: A prospective study was conducted over a period of one year in eligible lung cancer patients to evaluate the difference between ppoFEV1 and the 3-month postoperative FEV1 (poFEV1). Patients in whom CT was performed in another hospital and those with factors influencing poFEV1, such as atelectasis, pleural effusion, pneumothorax, or pneumonia, were excluded...

Mechanical ventilation (MV) is critical in the management of many patients with the acute respiratory distress syndrome (ARDS). However, MV can also cause ventilator-induced lung injury (VILI). The selection of an appropriate tidal volume is an essential part of a lung-protective MV strategy. Since the publication of a large randomized clinical trial demonstrating the benefit of lower tidal volumes, the use of tidal volumes of 6 mL/kg predicted body weight (PBW, based on sex and height) has been recommended in clinical practice guidelines...

Radiotherapy, particularly the target delineation of cancer based on scanned images, plays a key role in the planning of cancer treatment. Recently, diffusion-weighted magnetic resonance imaging (DW-MRI) has emerged as a prospective superior procedure compared with intensified computed tomography (CT) and positron emission tomography (PET) in the target delineation of cancer. However, the implication of DW-MRI in lung cancer, the leading cause of cancer-associated mortality worldwide, has not been extensively evaluated...

Pulmonary hamartomas are rare benign tumors consisting of multiple mesenchymal cell lines like cartilage, bone and fat. We discuss an interesting case of a 53-year-old male patient, who was referred to our clinic for persistent cough. Chest X-ray revealed a left suprahilar density associated with plate like atelectasis, which on chest CT was found to be a densely calcified nodule, causing narrowing of the left upper lobe (LUL) bronchus with calcified bilateral hilar lymph nodes. A bronchoscopy revealed a smooth endobronchial mass with calcification, which was removed...

AIM: Interstitial lung disease (ILD) in infants represents a rare and heterogenous group of disorders, distinct from those occurring in adults. In recent years a new entity within this category is being recognized, namely filamin A (FLNA) mutation related lung disease. Our aims are to describe the clinical and radiological course of patients with this disease entity to aid clinicians in the prognostic counseling and management of similar patients they may encounter. METHOD: A retrospective case note review was conducted of all patients treated at our institution (a specialist tertiary referral childrens' center) for genetically confirmed FLNA mutation related lung disease...

BACKGROUND: Flexible bronchoscopy (FB) is commonly performed to assess, diagnose, and treat patients with respiratory disease, and is typically performed via transnasal or transoral approaches. FB can be performed via tracheal tubes in patients with tracheostomies; however, the safety and technical feasibility has not been established. The present study evaluates the safety and feasibility of performing FB via tracheal tubes. MATERIALS AND METHODS: A total of 45 patients underwent 56 procedures involving FB via tracheal tubes at a single institution from November 2013 to November 2014 and were included in this retrospective case series...

Objective and importance Mounier Kuhn syndrome is usually diagnosed in adulthood, and only a few cases have been described in childhood. Clinical presentation We present the case of a seven-year-old boy suffering from recurrent pneumonia and atelectasis. Intervention Previously performed chest X-rays showed bilateral hyperinflation and tracheobronchomegaly. Chest computed tomography (CT) confirmed the presence of distal enlargement of trachea and bronchi. Tracheobronchomegaly associated with recurrent respiratory tract infections is consistent with Mounier Kuhn syndrome...

Arterial oxygen partial pressure can increase during inspiration and decrease during expiration in the presence of a variable shunt fraction, such as with cyclical atelectasis, but it is generally presumed to remain constant within a respiratory cycle in the healthy lung. We measured arterial oxygen partial pressure continuously with a fast intra-vascular sensor in the carotid artery of anaesthetized, mechanically ventilated pigs, without lung injury. Here we demonstrate that arterial oxygen partial pressure shows respiratory oscillations in the uninjured pig lung, in the absence of cyclical atelectasis (as determined with dynamic computed tomography), with oscillation amplitudes that exceeded 50 mmHg, depending on the conditions of mechanical ventilation...

Robotic-assisted laparoscopic radical prostatectomy (RARP) needs a steep Trendelenburg position and a relatively high CO2 insufflation pressure, and patients undergoing RARP are usually elderly. These factors make intraoperative ventilatory care difficult and increase the risk of perioperative pulmonary complications. The aim was to determine the efficacy of recruitment manoeuvre (RM) on perioperative pulmonary complications in elderly patients undergoing RARP. A total of 60 elderly patients scheduled for elective RARP were randomly allocated to two groups after induction of anaesthesia; positive end expiratory pressure (PEEP) was applied during the operation without RM in the control group (group C) and after RM in the recruitment group (group R)...

BACKGROUND: Gastrointestinal carcinoid tumours, despite their low malignant potential, frequently metastasize to the liver. While liver resection improves survival and provides symptomatic relief, multifocal bilobar disease complicates surgical management. METHOD: All patients with carcinoid liver secondaries managed by resection from 1990-2015 were identified from a prospective departmental database. Demographic data, operative management, morbidity using the Accordion classification and mortality were analysed...

BACKGROUND: The burden of HIV/AIDS in Sub-Saharan Africa has presented unusual and challenging acute surgical problems across all specialties. Thoraco-abdominal surgery cuts through muscle and thereby disrupts the normal anatomy and activity of the respiratory muscles leading to reduced lung volumes and putting the patients at greater risk of developing post-operative pulmonary complications (PPCs). PPCs remain an important cause of post-operative morbidity, mortality, and impacts on the long-term outcomes of patients post hospital discharge...
