While robot-assisted thoracic surgery (RATS) simplifies needle handling compared to video-assisted thoracic surgery (VATS), ligation remains challenging due to the lack of tactile feedback. To ensure closure of the bronchial segment by ligation in robotic surgery, we started a preliminary study to use dual barbed sutures that do not require ligation and clips for ligature fixation after the approval from the Ethics Committee of Mie University Hospital. We performed this procedure in five patients from January 2024 to present. Postoperative bronchoscopy, performed in four of the five patients, confirmed the bronchial stump was well closed in all cases, with no evidence of bronchopleural fistula( BPF). However, two patients experienced prolonged hospitalization due to midlobar torsion and prolonged air leakage requiring pleurodesis, respectively. The preliminary results suggest that this novel technique provides reliable bronchial stump closure in RATS. We plan to conduct a larger cohort study with long-term follow-up to further confirm the safety and long-term BPF rate.</p>","PeriodicalId":17841,"journal":{"name":"Kyobu geka.

To date, reports on robotic-assisted thoracic surgery (RATS) sleeve lobectomy are limited, with most literature focusing on right upper lobe reconstructions. Notably, even Cerfolio's landmark reports do not detail bronchial wedge resection or sleeve lobectomy of the middle and lower lobes. Using a 0° scope with an upward-viewing technique allows for the observation of target bronchi in the middle and lower lobes from a low intrathoracic angle. Although the interlobar pulmonary artery often obstructs the bronchial view in this approach, strategic retraction of the artery and lung parenchyma creates sufficient space for precise robotic anastomosis. The robotic platform provides a three-dimensional (3D) magnified view and enhanced dexterity, facilitating complex suturing even in narrow spaces. This surgical approach and the specific tips for field exposure may facilitate the wider adoption of minimally invasive bronchoplasty across various institutions.</p>","PeriodicalId":17841,"journal":{"name":"Kyobu geka.
