Robotic compared with laparoscopic cholecystectomy: A propensity matched analysis.

Background: As robotic surgery becomes more ubiquitous, determining clinical benefit is necessary to justify the cost and time investment required to become proficient. We hypothesized that robotic cholecystectomy would be associated with improved clinical outcomes but also increased cost as compared with standard laparoscopic cholecystectomy.

Materials And Methods: All patients undergoing robotic or laparoscopic cholecystectomy at a single academic hospital between 2007 and 2017 were identified using an institutional clinical data repository.

Inguinal hernia repair: is there a benefit to using the robot?

Background: The number of robotic surgical procedures performed yearly is constantly rising, due to improved dexterity and visualization capabilities compared with conventional methods. We hypothesized that outcomes after robotic-assisted inguinal hernia repair would not be significantly different from outcomes after laparoscopic or open repair.

Methods: All patients undergoing inguinal hernia repair between 2012 and 2016 were identified using institutional American College of Surgeons National Surgical Quality Improvement Program data.

Sex- and diagnosis-dependent differences in mortality and admission cytokine levels among patients admitted for intensive care.

Objectives: To investigate the role of sex on cytokine expression and mortality in critically ill patients.

Design: A cohort of patients admitted to were enrolled and followed over a 5-year period.

Setting: Two university-affiliated hospital surgical and trauma ICUs.

Differences in morbidity and mortality with percutaneous versus open surgical drainage of postoperative intra-abdominal infections: a review of 686 cases.

Intra-abdominal infections following surgical procedures result from organ-space surgical site infections, visceral perforations, or anastomotic leaks. We hypothesized that open surgical drainage is associated with increased patient morbidity and mortality compared with percutaneous drainage. A single-institution, prospectively collected database over a 13-year period revealed 2776 intra-abdominal infections, 686 of which required an intervention after the index operation.

Common complications in the surgical intensive care unit.

Surgical and trauma intensive care units provide the facilities, resources, and personnel needed to care for patients who have been severely injured, present with acute surgical emergencies, require prolonged and complex elective surgical procedures, or have severe underlying medical conditions. Correcting the immediately evident physiologic derangement is only the first step in the care of these patients, because in many cases their prognosis and ultimate outcome will depend on whether additional insults accrued during their intensive care unit and hospital stay will prevent them from a full recovery. The nature, number, and complexity of the interventions used to provide advanced support requires a unique attention to the concept of patient safety, particularly when the population involved is that most vulnerable to injury and with the least amount of physiologic reserve to recover from it.

Does preoperative ejection fraction predict operative mortality with left ventricular restoration?

Background: Ischemic cardiomyopathy and aneurysmal disease have been treated surgically with coronary artery bypass grafting in the past. The Dor technique for left ventricular restoration has demonstrated improved outcomes in patients with ischemic, akinetic ventricles. Our hypothesis was that even marked reduction in preoperative cardiac function (ejection fraction < .
