AI Article Synopsis

  • The study focuses on the use of multiport thoracoscopic surgery as a minimally invasive option for treating mediastinal tumors, with specific criteria for surgery based on tumor size and invasion.
  • They began utilizing one port surgery in 2017 and robot-assisted techniques in 2018, reviewing data from 269 patients over 12 years.
  • Results showed that while operating time and blood loss were significantly lower in one port surgery compared to the other methods, all approaches have expanded, providing more options for less invasive procedures.

Article Abstract

We have been performing multiport thoracoscopic surgery as a minimally invasive procedure for mediastinal tumors. The criteria for thoracoscopic surgery are as follow;tumor under 6 cm without invasion of great vessels, chest wall, or lung. We started one port surgery since 2017 and robot-assisted thoracoscopic surgery since 2018. We retrospectively reviewed these three approaches for mediastinal tumor for 12 years. 269 patients underwent surgery for mediastinal tumor, 141 patients by multiport surgery, 21 patients by one port surgery, and 38 patients by robot-assisted thoracoscopic surgery. Of 203 patients with anterior mediastinal tumors, 141 patients underwent thymectomy for thymic tumors (72 patients by multiport surgery, 9 patients by one port surgery, 17 patients by robot-assisted thoracoscopic surgery, and 43 patients by open surgery). There was no difference in tumor size, but the operating time and blood loss were significantly less in one port surgery than in multiport surgery or robot-assisted thoracoscopic surgery. The approaches have become more diverse, with a wider choice of surgical techniques, allowing us to offer more radical minimally invasive surgeries.

Objective: To investigate the efficacy of the SaCo videolaryngeal mask airway (VLMA) in combination with a bronchial blocker in patients undergoing minimally invasive thoracoscopic surgery.

Methods: A retrospective analysis was conducted on the clinical data of 120 patients who underwent minimally invasive thoracoscopic surgery from January 2022 to December 2023. Patients were grouped based on their treatment methods: 68 patients who received the SaCo VLMA combined with a bronchial blocker intraoperatively were designated as the L group, while 52 patients who received a tracheal tube combined with a bronchial blocker intraoperatively were designated as the E group.

Objective: Chronic post-surgical pain (CPSP) following thoracoscopic lung cancer surgery is a common and challenging complication. Identifying risk factors and predictive markers is essential for improving patient outcome.

Methods: In this retrospective case-control study, the clinical data from 106 patients with non-small cell lung cancer (NSCLC) who underwent thoracoscopic radical resection between January 2021 and December 2023 were comprehensively analyzed.

Pulmonary cavernous hemangioma: a case report.

Department of Medical Imaging, Baoji Central Hospital, Baoji, China.

Background: Cavernous hemangiomas can occur in various internal organs like the liver, kidney, bladder, and skin, or even in subcutaneous tissues. However, they rarely occur in the lungs, making pulmonary cavernous hemangiomas (PCH) an uncommon finding. Herein, we report a rare case of pulmonary cavernous hemangioma that was surgically resected.

Objectives: The study's goal is to find out if there is a link between the results of the 6-minute walk test (6MWT) done before surgery and the chance of getting pneumonia after surgery in people with stage I lung cancer who are having a video-assisted thoracoscopic lobectomy.

Methods: We conducted a retrospective analysis on data from 194 patients with lung cancer who underwent VATS lung resection between January 2020 and August 2023. We assessed the preoperative 6MWT findings and the likelihood of developing postoperative pneumonia using a logistic regression model.

Mediastinal lymphangiomas are rare benign tumors arising from lymphatic system malformations, most commonly seen in pediatric populations. In adults, they are exceedingly rare and present diagnostic challenges due to nonspecific symptoms and imaging overlap with other mediastinal masses. Diagnosis is typically based on imaging, including CT and MRI, with histopathology confirming the diagnosis.
