A survey of robotic surgery training curricula in general surgery residency programs: How close are we to a standardized curriculum?

BACKGROUND: Robotic surgery is increasingly adopted into surgical practice, but it remains unclear what level of robotic training general surgery residents receive. The purpose of our study was to assess the variation in robotic surgery training amongst general surgery residency programs in the United States. METHODS: A web-based survey was sent to 277 general surgery residency programs to determine characteristics of resident experience and training in robotic surgery. RESULTS: A total of 114 (41%) programs responded. 92% (n = 105) have residents participating in robotic surgeries; 68%(n = 71) of which have a robotics curriculum, 44%(n = 46) track residents' robotic experience, and 55%(n = 58) offer formal recognition of training completion. Responses from university-affiliated (n = 83) and independent (n = 31) programs were not significantly different. CONCLUSIONS: Many general surgery residencies offer robotic surgery experience, but vary widely in requisite components, formal credentialing, and case tracking. There is a need to adopt a standardized training curriculum and document resident competency.

Predictors of Mortality in Patients with Penetrating Inferior Vena Cava Injuries Surviving to the Operating Room.

Inferior vena cava (IVC) injuries are associated with significant morbidity and mortality. To identify clinical factors associated with mortality in patients undergoing operative intervention for penetrating IVC injuries, a retrospective review of 98 patients was performed, excluding blunt injuries (n = 20) and deaths before surgery (n = 16). The overall mortality was 58 per cent. Nonsurvivors more commonly presented with hypotension (50% vs 23%, P = 0.03) and underwent resuscitative thoracotomy more frequently (42% vs 4%, P = 0.01). Retrohepatic injuries were more common among nonsurvivors (P = 0.04). There was no difference in the use of ligation (7% vs 17%, P = 0.29) or the massive transfusion protocol (35% vs 25%, P = 0.41). On multivariate analysis, after controlling for mechanism of injury, admission hypotension, Glasgow Coma Scale score , preoperative cumulative fluids, resuscitative thoracotomy , absence of spontaneous tamponade, and location of IVC injury, the only independent predictor of mortality was the absence of spontaneous tamponade at the time of laparotomy (odds ratio = 5.4, 95% confidence interval: 1.11-25.95; P = 0.04). Penetrating IVC injuries continue to be associated with a high mortality, particularly among patients with free intraabdominal hemorrhage at laparotomy. Large multicenter studies are required to define the optimal resuscitative and operative management techniques in these severely injured patients.

The impact of a massive transfusion protocol on outcomes among patients with abdominal aortic injuries.

BACKGROUND: Injuries of the abdominal aorta are uncommon and associated with a high mortality. The purpose of this study was to examine the impact of an institutional massive transfusion protocol (MTP) on outcomes in patients with injuries of the abdominal aorta. METHODS: A 12.5-year retrospective analysis of a Level 1 trauma center database to identify patients with abdominal aortic injuries was conducted. Demographics, associated injuries and severity, operative procedures, resuscitation requirements, and outcomes were compared among patients before and after implementation of an MTP. RESULTS: Of the 46 patients with abdominal aortic injuries, 29 (63%) were in the pre-MTP group and 17 (37%) were in the post-MTP group. The mean age of the entire cohort was 32 ± 17 years and the two most common mechanisms of injury were gunshot wounds (63%) followed by motor vehicle collisions (24%). Thirteen patients (28%) underwent an emergency department thoracotomy and 11 patients (24%) sustained concomitant inferior vena cava injuries. There was a significant reduction in the volume of pre- and intraoperative crystalloids administered between the pre- and post-MTP groups. Intraoperatively, the use of tranexamic acid was increased in the post-MTP group (P < 0.001). A statistically significant difference in achievement of a low packed red blood cells to fresh frozen plasma ratio was observed for the post- versus the pre-MTP group (88% vs. 30%, P = 0.015). Overall survival was improved among post- versus pre-MTP patients (47% vs. 14%, P = 0.03). CONCLUSIONS: Abdominal aortic injuries continue to represent a challenge and remain associated with a high mortality. Modern improvements in damage control resuscitation techniques including implementation of an institutional MTP may improve outcomes in patients with these injuries.
