Lung-sparing surgery is relatively safe with few complications. In this study, the incidence of remnant lung lesions (a drawback of segmentectomy) was low. Thus, segmental resection affords results similar to those of lobectomy in patients with prenatally diagnosed CLM. Furthermore, segmental resection can preserve lung volume, thereby maintaining later pulmonary function. Therefore, elective segmental resection performed after precise identification of the lesions' locations may be highly beneficial for CLM patients.
Background: Recently, the use of extracorporeal membrane oxygenation (ECMO) in noncardiac surgery, such as thoracic surgery, has increased. However, there have been no studies on the mortality and incidence of intraoperative cardiac arrest with or without ECMO during thoracic surgery. Methods: Between January 2011 and October 2018, 63 patients received ECMO support during thoracic surgery. All patients who applied ECMO from starting at any time before surgery to the day of surgery were included. Patients were divided into the emergency ECMO group and the non-emergency ECMO group according to the timing of ECMO. We compared the factors related to 30 day mortality using Cox regression analysis. Results: The emergency ECMO and non-emergency ECMO groups comprised 27 and 36 patients, respectively. On the operation day, cardiopulmonary resuscitation (CPR) was a very important result, and only occurred in the emergency ECMO group (n = 20, 74.1% vs. 0%, p < 0.001). The most common cause of ECMO indication was the CPR in the emergency ECMO group and respiratory failure in the non-emergency ECMO group. There were significant differences in 30 day mortality between the emergency ECMO group and the non-emergency ECMO group (n = 12, 44.4% vs. n = 3, 8.3%, p = 0.001). The Kaplan–Meier analysis curve for 30 day mortality showed that the emergency ECMO group had a significantly higher rate of 30 day mortality than the non-emergency ECMO group (X2 = 14.7, p < 0.001). Conclusions: A lower incidence of intraoperative cardiac arrest occurred in the non-emergency ECMO group than in the emergency ECMO group. Moreover, 30 day mortality was associated with emergency ECMO.
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.
