Multicenter Study
The importance of patient-specific preoperative factors: an analysis of the society of thoracic surgeons congenital heart surgery database.
The most common forms of risk adjustment for pediatric and congenital heart surgery used today are based mainly on the estimated risk of mortality of the primary procedure of the operation. The goals of this analysis were to assess the association of patient-specific preoperative factors with mortality and to determine which of these preoperative factors to include in future pediatric and congenital cardiac surgical risk models. ⋯ Current STS-CHSD risk adjustment is based on estimated risk of mortality of the primary procedure of the operation as well as age, weight, and prematurity. The inclusion of additional patient-specific preoperative factors in risk models for pediatric and congenital cardiac surgery could lead to increased precision in predicting risk of operative mortality and comparison of observed to expected outcomes.

Quantifying the safety benefits of wedge resection: a society of thoracic surgery database propensity-matched analysis.
Wedge resection is often used instead of anatomic resection in an attempt to mitigate perioperative risk. In propensity-matched populations, we sought to compare the perioperative outcomes of patients undergoing wedge resection with those undergoing anatomic resection. ⋯ Wedge resection has a 37% lower mortality and 50% lower major morbidity rate than anatomic resection in these propensity-matched populations. The mortality benefit is most apparent in patients with forced expiratory volume in 1 second less than 85% predicted. These perioperative benefits must be carefully weighed against the increase in locoregional recurrence and possible decrease in long-term survival associated with the use of wedge resection for primary lung cancers.

Integrated positron emission tomography (PET) with computed tomography (CT) is a useful modality to investigate lymph node metastases for non-small cell lung cancer, but is less sensitive for normal-sized lymph nodes. We sometimes encounter cases with radiologically normal lymph nodes and unsuspected mediastinal metastases detected by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). However, few studies have investigated staging in patients with radiologically normal mediastina, and the accuracy of EBUS-TBNA staging for radiologically normal mediastina and hila is unclear. ⋯ The overall rate of unsuspected N2 was not low. EBUS-TBNA was accurate and feasible for preoperative mediastinal nodal staging of non-small cell lung cancer with both CT-negative and PET/CT-negative lymph nodes. The sensitivity of EBUS-TBNA for radiologically normal mediastina and hila was low. Further investigations are required.

Randomized Controlled Trial Multicenter Study
Long-term follow-up of high-risk patients in the National Emphysema Treatment Trial.
The National Emphysema Treatment Trial (NETT) was a randomized clinical trial designed to compare lung volume reduction surgery (LVRS) with maximal medical care for patients with severe emphysema. The trial was halted early for a subgroup of patients with severe lung disease. We report longer term follow-up for this high-risk subgroup. ⋯ The NETT was stopped early for high-risk patients with severe lung disease. Longer term follow-up suggests that surgical patients in this high-risk subgroup ultimately achieved comparable outcomes. The high risk of death within 30 days of the surgery may discourage use of the procedure for high-risk patients despite the potential for better long-term outcomes.

Postoperative lobar torsion is a rare and life-threatening complication. Several previous cases have been treated with completion lobectomy. We report successful surgical repair of middle lobar torsion after upper lobectomy. ⋯ The surface of the middle lobe appeared congestive, but its surface color, elasticity, and compliance improved 1 h after detorsion. We preserved the middle lobar function and prescribed warfarin for pulmonary vein thrombosis. When preserving a twisted lobe, it is important to consider the damage to the twisted lung, risk of thrombosis, and residual pulmonary function.
