Correlation between 10-meter walking speed and exercise capacity in patients with surgical resection for lung cancer.

Surgical resection for lung cancer adversely impacts exercise capacity. The 6-minute walk test (6MinWT) and cardiopulmonary exercise test (CPET) are commonly used to assess exercise capacity. However, these tests are difficult to use clinically because they must be performed by a trained technician using specialized equipment according to a prescribed method.

Fate of contralateral asymptomatic bullae in patients with primary spontaneous pneumothorax.

Objectives: This retrospective cohort study aimed to analyse the impact of asymptomatic blebs/bullae on the occurrence of primary spontaneous pneumothorax (PSP) by monitoring the natural course of contralateral blebs/bullae in patients with ipsilateral pneumothorax.

Methods: From January 2003 to December 2017, 1055 patients [age 19.6 ± 3.

Fate of spontaneous pneumothorax from middle to old age: how to overcome an irritating recurrence?

Background: The causes and treatment of pneumothorax in older patients are different from those in younger patients. However, studies on this topic are limited thus; pneumothorax in older patients is often inadequately managed. The purpose of this research was to investigate the characteristics of pneumothorax in patients over 45 years old, understand patterns of management and factors of recurrence, and propose reasonable guidelines for the treatment of older patients.

Stent Thrombosis After Short-term Discontinuation of Ticagrelor for Coronary Artery Bypass Grafting.

The optimum antithrombotic strategy before open heart surgery in patients with recently implanted coronary stents has not been clearly established because of lack of clinical evidence. This report describes a case of stent thrombosis in a patient who discontinued a P2Y inhibitor (ticagrelor) for 3 days before coronary artery bypass grafting. The period of withdrawal of antiplatelet drugs before coronary artery bypass grafting should be minimized in patients with recently implanted drug-eluting coronary stents to prevent stent thrombosis.

Do Blebs or Bullae on High-Resolution Computed Tomography Predict Ipsilateral Recurrence in Young Patients at the First Episode of Primary Spontaneous Pneumothorax?

Background: The relationship between the size of bullae and pneumothorax recurrence is controversial. The aim of this study was to retrospectively evaluate the role of blebs or bullae in predicting ipsilateral recurrence in young patients experiencing their first episode of primary spontaneous pneumothorax (PSP) who underwent conservative treatment.

Methods: A total of 299 cases of first-episode PSP were analyzed.

Diaphragmatic hernia with isolated shoulder pain evoked by surfeit.

Bochdalek hernia in adult is extremely rare, so symptoms or indications of surgery are not reported enough. Here we report a case of small-sized Bochdalek hernia with isolated shoulder pain that resolved after surgical reduction of hernia. A 25-year-old man with diaphragmatic mass was referred to out-patient clinic.

Robot-assisted laparoscopic surgery versus conventional laparoscopic surgery in randomized controlled trials: A systematic review and meta-analysis.

Importance: This review provides a comprehensive comparison of treatment outcomes between robot-assisted laparoscopic surgery (RLS) and conventional laparoscopic surgery (CLS) based on randomly-controlled trials (RCTs).

Objectives: We employed RCTs to provide a systematic review that will enable the relevant community to weigh the effectiveness and efficacy of surgical robotics in controversial fields on surgical procedures both overall and on each individual surgical procedure.

Evidence Review: A search was conducted for RCTs in PubMed, EMBASE, and Cochrane databases from 1981 to 2016.

Pulmonary resection for patients with multidrug-resistant tuberculosis based on survival outcomes: a systematic review and meta-analysis.

We investigated the survival benefit of pulmonary resection for patients with multidrug-resistant tuberculosis. To weigh the survival benefit of pulmonary resection for patients with multidrug-resistant tuberculosis who have undergone surgical treatment combined with medical chemotherapy compared with medical chemotherapy alone, we did a meta-analysis of available studies containing a hazard ratio for pulmonary resection. Among 1726 articles, 6 clinical reports, with a mean sample size of 47 patients per report, met the inclusion criteria.
