Surgeons increasingly use robot-assisted minimally invasive surgery for a variety of medical conditions. For hospitals, the acquisition and maintenance of a robot requires a significant investment, but financial returns are not linked to any improvement in long-term patient outcomes in the current reimbursement environment. Kidney cancer provides a useful case study for evaluating the long-term value that this innovation can provide. Kidney cancer is generally treated through partial or radical nephrectomy, with evidence favoring the former procedure for appropriate patients. We found that robot-assisted surgery increased access to partial nephrectomy and that partial nephrectomy reduced mortality and renal failure. The value of the benefits of robot-assisted minimally invasive surgery to patients, in terms of quality-adjusted life-years gained, outweighed the health care and surgical costs to patients and payers by a ratio of five to one. In addition, we found no evidence that the availability of robot-assisted minimally invasive surgery increased the likelihood that inappropriate patients received partial nephrectomy.

Introduction Patients undergoing emergent surgical procedures after penetrating trauma can benefit from postoperative imaging studies to identify potential missed injuries or indications to additional surgery. Aim of this study is to describe postoperative imaging findings in patients who underwent emergent operation for thoracic gunshot wounds (GSWs) and the subsequent need for further surgery, diagnostic evaluations or consults. Methods Patients who survived to receive imaging evaluation after emergency surgery for penetrating chest trauma in a level I trauma center between 2017 and 2021 were included. Results of postoperative diagnostic evaluation were screened to determine their impact on the subsequent management. Results Overall, 125 patients admitted with a thoracic GSW underwent an emergent surgical procedure and 29 survived to receive postoperative imaging and were included. Postoperative CT-scan was performed in 26 (89.6%) patients, echocardiography in 8 (27.5%). Other tests included esophagoscopy (1) and bronchoscopy (1). Impact on management of abnormal imaging included a new indication to surgery or additional procedures in 7 cases and need for additional imaging or consults in other 8 cases. Bone fractures and lung injuries were more often diagnosed on postoperative CT-scan. In 3 patients, abnormal echocardiographic findings led to a second cardiac operation. Conclusion Following emergency surgery for penetrating trauma, completion of injury assessment with CT-scan can lead to identification of missed or additional injuries, while other imaging is indicated according to operative findings. In this study, 24.1% had additional surgical pathology identified by postoperative imaging while others had findings requiring additional studies or specialist consult evaluations.
