Current New Approach in Thoracoscopic Surgery: Non-Intubated Uniportal Video-Assisted Thoracoscopic Surgery (Ni-Univats)
(Mdpi, 2025) Agar, Mehmet; Gulcek, Ilham; Kalkan, Muhammed; Ulutas, Hakki; Celik, Muhammet Reha; Aksu, Ahmet; Cakmak, Muharrem
Background and Objectives: Non-intubated uniportal video-assisted thoracoscopic surgery (NI-UniVATS) is a minimally invasive technique performed using a single port, allowing the entire surgical procedure to be completed with spontaneous breathing without the need for general anesthesia. Materials and Methods: This retrospective study included 51 patients who underwent NI-UniVATS between 2020 and 2023. The intraoperative and postoperative data of patients who underwent NI-UniVATS were evaluated. Results: Among the cases, 37 (72.5%) were male, and 14 (46.6%) were female, with a mean age of 47.73 +/- 20.43 years (range: 18-78 years). The mean operative time was 25.92 +/- 7.31 min. No perioperative complications were observed in any patient. The mean postoperative hospital stay was 4.17 +/- 1.76 days (range: 2-9 days). A right hemithoracic approach was performed in 28 patients (54.9%), whereas a left hemithoracic approach was used in 23 patients (45.1%). The procedures performed included wedge resection in 27 patients (52.9%), biopsy in 22 patients (43.1%), pericardial window creation in one patient (2%), and intrathoracic foreign body removal in one patient (2%). Conclusions: NI-UniVATS allows for safer surgery by preventing the adverse effects and complications associated with general anesthesia. NI-UniVATS can be recommended as a safe and feasible approach for both minor and major thoracic procedures.
The first uniportal VATS sleeve lobectomy in Türkiye: A case report
(2024) Hakkı ULUTAŞ; Gülçek, İlham; Kalkan, Muhammed
In recent years, video-assisted thoracic surgery (VATS) has become the gold standard approach in the surgical treatment of early-stage non-small cell lung cancer. Especially in cases of central tumors, sleeve lobectomies that preserve parenchyma and respiratory reserves are performed instead of pneumonectomies by experienced clinics. Here, we present the first case of uniportal VATS right bronchial sleeve upper lobectomy for right main bronchial invasion in Turkey, which was successfully performed in August 2022. A patient diagnosed with laryngeal carcinoma who had been in remission for 5 years complained of a cough. Computed thoracic tomography showed hilar peribronchial thickening and an endobronchial lesion (EBL) extending from the right upper lobe bronchus to the main bronchus, almost completely obstructing the upper lobe bronchus. Bronchoscopy revealed that the right upper lobe entrance was obstructed with EBL, and its distance to the carina was 1.6 cm. Bronchoscopic biopsy revealed squamous cell carcinoma. The thorax was entered through an incision of approximately 3 cm in the right fifth intercostal space. First, the right upper lobe pulmonary arteries and superior pulmonary vein were dissected and cut. The main bronchus was divided until the intermediate bronchus. With the help of an endoscissor, the main and intermediate bronchus were incised with appropriate surgical margins, and the lobectomy material was removed. Both macroscopic appearance and frozen and microscopic main and intermediate bronchus surgical margin tumor negativity were confirmed. One suture was passed through the lateral cartilage from the inside out, and the needle was fixed to the posterior pleura. Membranous and cartilage parts were continuously anastomosed with a double-needle 3/0 prolene suture at 2–3 mm intervals. Pathological evaluation confirmed squamous cell carcinoma with a tumor diameter of 1.7 cm, hilar 1/11 lymph node metastasis, and negative surgical margin. Adhering to oncologic principles, sleeve resections, which are difficult even with the currently known open techniques, can be performed effectively and safely with uniportal VATS in experienced centers.

Utilising Uniportal Video-Assisted Thoracoscopic Surgery for Pericardial Window: A 12-Year Single-Centre Experience in the Diagnosis and Treatment of Pericardial Effusion
(Wolters Kluwer Medknow Publications, 2025) Agar, Mehmet; Gulcek, Ilham; Kalkan, Muhammed; Ulutas, Hakki; Celik, Muhammet Reha
Introduction:Uniportal video-assisted thoracoscopic surgery (Uni-VATS) is an effective minimally invasive technique for pericardial drainage, biopsy and window creation in cases of pericardial effusion (PE).Patients and Methods:This retrospective study evaluated 73 patients with PE who underwent pericardial window procedures between 2012 and 2024. Intraoperative and post-operative data related to Uni-VATS were assessed.Results:The mean age of the patients was 53.79 +/- 17.79 years (10-82 years), with 34 (46.6%) females and 39 (53.4%) males. The mean volume of pericardial fluid drained after window creation was 446.23 +/- 199.81 cc (75-1100 cc). The mean operation time was 42.87 +/- 12.79 min, and chest drain removal occurred after an average of 1.8 +/- 1.2 days. The mean duration until discharge or referral to the follow-up clinic was 5.98 +/- 2.14 days. In addition to the pericardial window procedure, pleural biopsy was performed in 12 patients, mediastinal mass biopsy in eight patients and wedge resection for parenchymal nodules in six patients. Microbiologic and virologic cultures of the fluids were negative in all cases. Among the 41 patients with benign cytology, pericardial biopsy results indicated tuberculosis in four patients (5.4%), amyloidosis in one patient (1.3%) and chronic or subacute nonspecific pericarditis in the remaining patients.Conclusion:Uni-VATS is a novel and safe technique that may be the preferred choice for pericardial window due to its diagnostic and therapeutic efficacy, ability to perform simultaneous procedures, favourable impact on operation duration/hospital stay, low complication rates and superiority compared to traditional methods.
