Left Upper Lobectomy vs Trisegmentectomy for Lung Cancer: A Propensity Score-Matched Comparison.

Background: The left upper division (segments I-III) and the lingula (segments IV and V) are analogous to the right upper and middle lobes, respectively. Whereas bilobectomy for right upper lobe tumors is rare, left upper division tumors are often resected by left upper lobectomy (LUL) rather than by left upper trisegmentectomy (LU3S). To assess safety and oncologic efficacy of LUL vs LU3S, we compared short- and long-term outcomes after both procedures.

Predictors of prolonged hospital stay after segmentectomy.

Objective: Segmentectomy is becoming the standard of care for small, peripheral non-small cell lung cancer. To improve perioperative management in this population, this study aims to identify factors influencing hospital length of stay after segmentectomy.

Methods: Patients who underwent segmentectomy for any indication between January 2018 and May 2023 were identified using a prospectively maintained institutional database.

Complete anatomic segmentectomy shows improved oncologic outcomes compared to incomplete anatomic segmentectomy.

Objectives: To compare oncologic outcomes after segmentectomy with division of segmental bronchus, artery and vein (complete anatomic segmentectomy) versus segmentectomy with division of <3 segmental structures (incomplete anatomic segmentectomy).

Methods: We conducted a single-centre, retrospective analysis of patients undergoing segmentectomy from March 2005 to May 2020. Operative reports were audited to classify procedures as complete or incomplete anatomic segmentectomy.

Time between imaging and surgery is not a risk factor for upstaging of clinical stage IA non-small-cell lung cancer.

Objectives: The timing of preoperative imaging in patients with lung cancer is a debated topic, as there are limited data on cancer progression during the interval between clinical staging by imaging and pathological staging after resection. We quantified disease progression during this interval in patients with early stage non-small-cell lung cancer (NSCLC) to better understand if its length impacts upstaging.

Methods: We retrospectively reviewed our institutional database to identify patients who underwent surgery for clinically staged T1N0M0 NSCLC from January 2015 through September 2022.

Spontaneous pneumomediastinum in COVID-19 patients. Case series.

Spontaneous pneumomediastinum is defined as the presence of free air within the mediastinum without an apparent cause such as chest trauma. It is a benign, self-limiting condition that is conservatively treated. Clinical diagnosis is based on two symptoms: chest pain and dyspnea; and on a particular sign: subcutaneous emphysema.

Absence of an Additional Metabolic Effect of Body Contour Surgery in Patients With Massive Weight Loss After Laparoscopic Roux-En-Y Gastric Bypass.

Introduction: Body contour surgery (BCS) is a combination of soft tissue resections that have proven to be an effective treatment for the aesthetic and functional problems related to massive weight loss (MWL). There are no studies analyzing the metabolic effect of large volume adipose tissue flap resection in patients with MWL after bariatric surgery.

Methods: This study was a retrospective review of adults who underwent BCS after gastric bypass.

Clinical Characteristics and Mortality of Influenza A H1N1 and Influenza-Like Illness in Mexico City in the 2013-2014 Winter Season.

Background: The 2013-2014 influenza season in Mexico City was severe and mainly due to influenza A H1N1, as was the 2009 pandemic.

Objective: To describe features of the outbreak and to compare the characteristics of patients with and without viral identification.

Methods: We reviewed the medical charts of all individuals with influenza or influenza-like illness admitted to a referral hospital for respiratory diseases in Mexico City from January 2013 to March 2014, whether influenza virus was identified or not.
