Background: Intraoperative fluid management based on pulse pressure variation has shown potential to reduce postoperative pulmonary complications (PPCs) and improve clinical outcomes in various surgical settings. However, its efficacy and safety have not been assessed in patients undergoing thoracic surgery with one-lung ventilation. Methods: Patients scheduled for pulmonary lobectomy using uniportal video-assisted thoracic surgery approach were randomly assigned to two groups. In the PPV group, fluid administration was guided by the pulse pressure variation parameter, while in the near-zero group, it was guided by conventional hemodynamic parameters. The primary outcome was the partial pressure of oxygen (PaO2)/ fraction of inspired oxygen (FiO2) ratio 15 min after extubation. The secondary outcomes included extubation time, the incidence of postoperative pulmonary complications in the first three postoperative days, and the length of hospital stay. Results: The PaO2/FiO2 ratio did not differ between the two groups (364.48 ± 38.06 vs. 359.21 ± 36.95; p = 0.51), although patients in the PPV group (n = 44) received a larger amount of both crystalloids (1145 ± 470.21 vs. 890 ± 459.31, p = 0.01) and colloids (162.5 ± 278.31 vs 18.18 ± 94.68, p = 0.002) compared to the near-zero group (n = 44). No differences were found in extubation time, type and number of PPCs, and length of hospital stay. Conclusions: PPV-guided fluid management in thoracic surgery requiring one-lung ventilation does not improve pulmonary gas exchange as measured by the PaO2/FiO2 ratio and does not seem to offer clinical benefits. Additionally, it results in increased fluid administration compared to fluid management based on conventional hemodynamic parameters. [ABSTRACT FROM AUTHOR]

Simple Summary: Uniportal video-assisted thoracoscopic segmentectomy is one of the most minimally invasive surgeries for early-stage lung cancer. However, mastering this technique requires high levels of skill and experience, especially in complex cases. This article reviews previous research on uniportal video-assisted thoracoscopic segmentectomy, including indications, instrument selection, tumor marking, intersegmental plane identification, lymph node dissection, and surgical videos. Twenty years have passed since uniportal video-assisted thoracoscopic surgery (VATS) was first reported. Several reports have already proven the minimal invasiveness of uniportal VATS. In addition, two large clinical trials recently demonstrated the benefits of segmentectomy for small peripheral early-stage non-small cell lung cancer. Uniportal VATS segmentectomy is considered the most beneficial minimally invasive surgery for patients with early-stage lung cancer. However, a high level of skill and experience are required to achieve this goal. Only a few reports have discussed specific techniques, particularly for complex segmentectomies. In this Special Issue, we reviewed previous reports on uniportal VATS segmentectomy regarding the indications, instrument selection, marking of the tumor location, methods of intersegmental plane identification, and lymph node dissection, including our own techniques with video content.

Objective: To determine the postoperative outcomes of video-assisted thoracoscopic single port surgery (VATS) in the treatment of pleural empyema. Methods: This case series was conducted at Department of thoracic Surgery, Karachi. It was 16 months study from September 2020 to January 2022. Total 170 patients of both genders were included. Informed and written consent was taken from all included patients. Complete history and thorough clinical examination of patients were obtained. All operations were employing one lung ventilation, general anesthesia, and a double-lumen endotracheal tube. Each and every patient was followed up till 4 weeks to assess the postoperative outcomes. Data was compiled and analyzed using SPSS-21. Results: In this study mean age was 56.9±17.7 years. Out of 170 patients, 97 (57%) were male and 73 (43%) female. The postoperative outcomes of U-VATS in the treatment of pleural empyema were determined, mean operation time was 130.0±64.6minutes, mean pain score at first post-operative day was 2 ± 1.6, the mean duration of pain was 2.5±2.1 days, mean pain score after removal of chest tube was 0.33±0.9 and mean cosmetic score was 2.45±0.4. Postoperative paresthesia was observed in 9 (5.3%) cases, no wound infection was observed and satisfactory re-expansion of lung was noted in 154 (90.5%) cases. Conclusion: Even in stages 1 and 2 of the condition, pleural empyema can be effectively treated with U-VATS, and the procedure has relevant postoperative outcomes in terms of reduced discomfort, less complications, and aesthetic improvements.

Abstract Objective This study aimed to explore the feasibility and advantages of a modified chest tube suture-fixation technique in uniportal video-assisted thoracic surgery for pulmonary resection. Methods A retrospective analysis was conducted on 116 patients who underwent uniportal video-assisted thoracic surgery (U-VATS) for lung diseases in Zhengzhou People’s Hospital between October 2019 and October 2021. Patients were stratified into two groups based on the applied suture-fixation methods, i.e., 72 patients in the active group and 44 patients in the control group. The two groups were subsequently compared in the terms of gender, age, operation method, indwelling time of chest tube, postoperative pain score, chest tube removal time, wound healing grade, length of hospital stay, incision healing grade, and patient satisfaction. Results There was no significant difference between the two groups in terms of gender, age, operation method, indwelling time of chest tube, postoperative pain score, and length of hospital stay (P = 0.167, 0.185, 0.085, 0.051, 0.927, and 0.362, respectively). However, the chest tube removal time, incision healing grade, and incision scar satisfaction in the active group were significantly better compared with those of the control group (P =

However, the chest tube removal time, incision healing grade, and incision scar satisfaction in the active group were significantly better compared with those of the control group (P = < 0.001, 0.033, and < 0.001, respectively). Conclusion: In summary, the new suture-fixation approach can minimize the number of stitches, and time necessary for chest tube removal process, and avoid the pain experienced when removing the drainage tube. This method is more feasible, has better incision conditions, and provides a convenient tube removal, making it more suitable to patients. [ABSTRACT FROM AUTHOR]

• Ectopic thyroid tissue is a rare entity. • Few cases of ectopic thoracic thyroid resected by uniportal VATS have been described in the literature. • Uniportal VATS has demonstrated its feasibility and safety compared to conventional techniques by several advantages. Ectopic thyroid tissue is a rare entity, and accounts for approximately 1% of all mediastinal tumours. It is a differential diagnosis of the mediastinum tumors or metastatic deposits from an orthotopic gland, as well as other benign or malignant masses. Although most cases are asymptomatic and discovered incidently by imaging, symptoms related to tumor size and its compression of adjacent structures may also appear which necessites explorations and lead to diagnosis. This is a 59-year-old women, followed for glaucoma and operated for bilateral congenital cataract reffered to our structure by the service of pnemology for a right laterotracheal mediastinal mass. The patient presented respiratory symptoms over four months, and the physical examination found patient in good condition with PS 0 and normal vital signs, a poor oral health was noticed. The CT scann showed a left basal opacity and a right laterotracheal mediastinal mass at the upper right mediastinum, pushing forward the superior vena cava and compressing the trachea on the contralateral side, with well-defined borders and without signs of infiltration of adjacent structure. The brochoscopy was perfomed which showed the yellowish granulous aspect and the pathophysiology revealed a pulmonary actinomycosis. The patient was treated with antibiotic based on parenteral infusion of penicillin G at 20 million / day for 6 weeks relayed by oral administration of 3 g / day for 3 months with a good response and the left basal opacity disappeared on the CT control but the mediastinal mass persisted. After multidisciplinary concertation, the mediastinoscopy was perfomed and has revealed an ectopic thyroid which was removed by Uniportal Videoassisted Thoracoscopic Surgery (U-VATS) approach. The first case of ectopic thyroid gland was described by Hickman in 1869, since a few cases have been reported by the literature. Its prevalence is about 1 per 100 000–300 000 people, rising to 1 per 4000–8000 patients with thyroid disease. The main techniques indicated in the management of undetermined lesions of the anterior mediastinum, are midline exploratory sternotomy, anterior lateral thoracotomy and VATS. U-VATS has demonstrated its feasibility and safety compared to conventional techniques by several advantages. Ectopic mediastinal thyroid is an unusual presentation of thyroid pathology. Complete surgical resection remains a therapeutic and a key diagnosis. The aim of this study is to prouve the feasibility, efficiency and efficacity of U-VATS approach as minimally invasive thoracic surgery for mediastinal mass resection. [ABSTRACT FROM AUTHOR]
