BackgroundSoft coagulation using the VIO soft coagulation system is used to treat minor lung air leaks during pulmonary resection in Japan. We previously reported that it has a similar effect as the air leak treatment with fibrin glue. We evaluated the efficacy of soft coagulation using the VIO soft coagulation system for lung air leakage during pulmonary resection.MethodsIntraoperative air leaks from the interlobar lung parenchyma were observed in 42 of the 283 patients who underwent video-assisted thoracoscopic surgery lobectomy between 2016 and 2018. We retrospectively reviewed these 42 patients who were treated using the VIO soft coagulation system for air leaks. We classified the air leaks in to grades using the Macchiarini scale score and evaluated the surgical outcomes of air leak treatment.Results Air leaks from the interlobar lung parenchyma having Macchiarini scale scores 1, 2, and 3 occurred in 8, 17, and 17 patients, respectively. In all the 8 patients with score 1 air leaks (100%), the air leaks could be controlled using the VIO soft coagulation system alone, and none had delayed pneumothorax requiring intervention. Of the score 2 and 3 air leaks, 52.9% and 35.3% were controlled using the VIO soft coagulation system alone, respectively.Conclusions Macchiarini scale score 1 air leaks from the interlobar lung parenchyma could be well controlled using the VIO soft coagulation system. Therefore, soft coagulation with this system may be an alternative method for treating minor air leaks during pulmonary resection surgery.

“… 10 , 11 The major advantages of RATS are the unobstructed field of view provided by high-precision 3D images and the excellent operability provided by the robot arms, which enable precise movement in a narrow surgical field. 8 These features of RATS allow thorough LN dissection, which is technically demanding, relatively easy. However, limited and conflicting perioperative outcomes have been reported for different cohorts.…”

Background
Soft coagulation using the VIO soft coagulation system is used to treat minor lung air leaks during pulmonary resection in Japan. We previously reported that it has a similar effect as the air leak treatment with fibrin glue. We evaluated the efficacy of soft coagulation using the VIO soft coagulation system for lung air leakage during pulmonary resection.
Methods
Intraoperative air leaks from the interlobar lung parenchyma were observed in 42 of the 283 patients who underwent video-assisted thoracoscopic surgery lobectomy between 2016 and 2018. We retrospectively reviewed these 42 patients who were treated using the VIO soft coagulation system for air leaks. We classified the air leaks in to grades using the Macchiarini scale score and evaluated the surgical outcomes of air leak treatment.
Results
Air leaks from the interlobar lung parenchyma having Macchiarini scale scores 1, 2, and 3 occurred in 8, 17, and 17 patients, respectively. In all the 8 patients with score 1 air leaks (100%), the air leaks could be controlled using the VIO soft coagulation system alone, and none had delayed pneumothorax requiring intervention. Of the score 2 and 3 air leaks, 52.9% and 35.3% were controlled using the VIO soft coagulation system alone, respectively.
Conclusions
Macchiarini scale score 1 air leaks from the interlobar lung parenchyma could be well controlled using the VIO soft coagulation system. Therefore, soft coagulation with this system may be an alternative method for treating minor air leaks during pulmonary resection surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
