OBJECTIVE The use of the da Vinci Robot has been fast growing in general surgery in the United States over the past decade. While the financial cost of robot-assisted procedures has been studied, there has been limited research on the educational cost of the robotic approach on general surgery trainees, and their surgical skills. DESIGN Analysis of anonymous educational survey responses collected from residents, in addition to case logs which were used as a retrospective review for the 5 years preceding the survey. SETTING One thousand bed, tertiary care hospital general surgery residency program. PARTICIPANTS Twenty-four enrolled general surgery residents in 2018. RESULTS There has been a rapid expansion in the use of robotics in general surgery. In 2017 the total number of general surgery cases using the da Vinci robot increased 6 fold over that in 2013 (23 cases in 2013, 136 in 2017), while both open and laparoscopic procedures have witnessed about a 33% drop in the case volume during those years. Almost all residents would prefer a residency program which offers the da Vinci robot for care and training (95%), however, 38% of general surgery residents reported that the presence of robotic-assisted surgery had a “detrimental” effect on their surgical training. Senior residents were more likely to report a “detrimental” effect (56% vs 27%). A third of the residents believe that robotic surgery is impeding their ability to learn open and laparoscopic surgical techniques, and only 25% denied a negative impact. Senior residents are more likely to report this negative impact (67% vs 13%). CONCLUSIONS Reforms in residency curricula need to be in place to accommodate the expansion of the use of the robotic platform in general surgery. A subjective survey of the residents suggests that robotic surgery can potentially impede the development of residents’ open and laparoscopic surgical skills.

Introduction Surgeons in practice have limited opportunities to learn new techniques and procedures. Traditionally, in-person hands-on courses have been the most common means for surgeons to gain exposure to new techniques and procedures. The COVID19 pandemic caused a cessation in these courses and left surgeons with limited opportunities to continue their professional development. Thus, SAGES elected to create an innovative hands-on course that could be completed at home in order to provide surgeons with opportunities to learn new procedures during the pandemic. Methods This course was initially planned to be taught as an in-person hands-on course utilizing the Acquisition of Data for Outcomes and Procedure Transfer(ADOPT) method 1. We identified a virtual telementoring platform, Proximie Ltd(London, UK), and a company that could create a model of an abdominal wall in order to perform a Transversus Abdominis Release, KindHeart™(Chapel Hill, NC, USA). The course consisted of pre-course lectures and videos to be reviewed by participants, a pre-course call to set learning goals, the hands-on telementoring session from home, and monthly webinars for a year. Results The ADOPT hands-on hernia course at home was successfully completed on October 23rd of 2020. All participants and faculty were successfully able to set up their model and utilize the telementoring platform, but 15% required assistance. Post course-surveys showed that participants felt that the course was successful in meeting their educational goals and felt similar to prior in-person courses. Conclusions SAGES was successfully able to transition and in-person hands-on course to a virtual at-home format. This innovative approach to continuing professional development will be necessary during the times of the COVID19 pandemic, but may be a helpful option for rural surgeons and others with travel restrictions in the future to continue their professional development without the need to travel away from their practice.

Bacteremia is a worrisome postoperative complication and blood cultures (BCx) are often nondiagnostic. We previously reported a 4 per cent overall yield of positive cultures in postoperative patients. To reduce unnecessary testing, we present a predictive model to identify patients in whom growth of pathogens is unlikely and provide a clinical decision-making guide. Retrospective analysis of nonpregnant patients ≥18 years who had BCx within 10 days postoperatively was performed. Generalized linear mixed models identified clinical predictors of high- and low-yield cultures. A clinical algorithm was created using significant predictors, and positive predictive value, negative predictive value, sensitivity, and specificity calculated. Among 1759 BCx, hypotension, maximum temperature ≥101.5 °F within 24 hours of culture, and culture collected after postoperative day (POD) two were statistically significant predictors of positive cultures. Forty nine per cent of BCx were sent ≤ POD 2, and

Background Aberrations in calcium homeostasis are common in critically ill patients. The proper method to evaluate this issue in surgical patients has not been completely defined. Methods Medical records of patients admitted to a university-affiliated, tertiary-care surgical intensive care unit were retrospectively reviewed. Calcium status was evaluated by ionized levels and as a function of serum calcium levels corrected for albumin aberrations. Results Corrected serum calcium values failed to accurately classify calcium status in 38% of cases. The sensitivity and specificity of the corrected serum calcium formula to evaluate hypocalcemia were 53% and 85%, respectively. Corrected serum values underestimated the prevalence of hypocalcemia and overestimated the prevalence of normocalcemia. No factors were able to discern which patients could be evaluated by corrected serum calcium levels. Conclusions Calcium homeostasis should be evaluated by ionized calcium levels rather than as a function of serum calcium and albumin levels.

The purpose of this study was to compare flexion and extension (F/E) cervical radiographs with CT of the cervical spine in patients sustaining blunt trauma for the evaluation of ligamentous injury. A retrospective chart review of 2 years duration at an American College of Surgeons-verified Level I trauma center was performed. All patients sustaining blunt trauma who were evaluated with both a CT as well as F/E radiographs were identified. Exclusion criteria included penetrating injuries, neurologic symptoms, and age younger than 18 years. Follow-up MRI of each positive F/E radiograph after a negative CT scan was performed. Flexion and extension cervical radiographs were obtained in 379 patients after CT. Eight positive F/E radiographs were obtained after a negative CT scan. Follow-up MRI was negative for ligamentous injury in all cases. No cases of a clinically relevant positive F/E radiograph after a negative CT scan were identified. Follow-up F/E radiographs are not efficacious when a negative CT has been performed in blunt trauma without neurologic findings.

Splenomegaly is a sequela of infectious mononucleosis. The potential for traumatic rupture of an enlarged spleen is well recognized. Recently, splenic artery embolization has gained popularity for the treatment of splenic injury. However, embolization has not been described for splenic injury in an enlarged spleen secondary to mononucleosis. We report the case of a 15-year-old girl who was the restrained passenger in a motor vehicle crash. On examination at an American College of Surgeons-verified Level 1 trauma center, the patient was found to have abdominal pain. A focused assessment with sonography for trauma examination revealed fluid in Morison's pouch. A subsequent spiral CT scan with intravenous contrast revealed a markedly enlarged spleen with a shattered upper pole. The patient denied symptoms of mononucleosis; however, a spot mononucleosis test was positive. The patient was admitted to the pediatric intensive care unit for observation. She remained hemodynamically stable, but her initial hemoglobin of 9.2 g/dL fell to 7.1 g/dL 6 hours later. Splenic artery embolization was performed and the upper pole of the spleen was selectively embolized. The hemoglobin remained stable and the patient was transferred to the pediatric ward. On postembolization day five, the patient was dismissed with a hemoglobin of 9.7 g/dL. This case demonstrates that splenic embolization is a viable alternative to operative treatment even in the presence of splenomegaly secondary to mononucleosis.

Background: Surgeon-performed ultrasound has become ubiquitous in the trauma suite. Initial reports suggest that sonography may be used for the detection of pneumothorax. The purpose of this study was to evaluate the efficacy of sonography to rule out the presence of a pneumothorax in the trauma population. Methods: A prospective analysis of 328 consecutive trauma patients at an American College of Surgeons-verified Level I trauma center was undertaken. Thoracic ultrasound was performed before chest radiography. The presence or absence of a sliding-lung sign or comet-tail artifact was recorded. Results: Of 328 evaluations, there were 312 true-negatives, 12 true-positives, 1 false-negative, 1 false-positive, and 2 exclusions. Specificity, negative predictive value, and accuracy were 99.7%, 99.7%, and 99.4%, respectively. Conclusion: Ultrasound is a reliable modality for the diagnosis of pneumothorax in the injured patient. This modality may serve as an adjunct or precursor to routine chest radiography in the evaluation of injured patients.

A 43-year-old woman presented with gunshot wounds to the neck, chest, and left thigh. Computed tomography of the neck and chest with intravenous contrast revealed a left common carotid pseudoaneurysm and a foreign body in the right atrium. Preoperative chest x-ray and CT scan confirmed a metallic foreign body in the right heart. At median sternotomy, the intracardiac foreign body could not be located using fluoroscopy. The foreign body (bullet) was subsequently removed in the cardiac catheterization laboratory using a percutaneous transvenous basket extraction through a right femoral vein cutdown.

BACKGROUND The Emergency Nurses Association (ENA) has formally resolved that family presence (FP) during resuscitation and invasive procedures (TR) is the right of the patient and is beneficial for both patients and family members. Furthermore, FP during TR has been implemented at several trauma centers. Because this policy is controversial, a survey was conducted to assess the opinions of members of the American Association for the Surgery of Trauma (AAST) and ENA in regard to FP. METHODS A survey instrument regarding FP during TR was mailed to the AAST membership (n = 813) and a random sampling (10%) of ENA members (n = 2,988). Questions regarding membership (AAST vs. ENA), age, gender, years in practice, trauma experience, the patient's right to FP during the primary survey, secondary survey, and invasive procedures, the potential effects of FP on trauma team function, and medicolegal implications were included in the survey. Qualitative and quantitative variables were analyzed by analysis of variance and chi2 analysis, respectively. Responses to questions by using a Likert Scale for degree of agreement were analyzed by using the Kruskal-Wallis test. RESULTS A total of 1,629 (AAST, n = 368; ENA, n = 1,261) surveys were returned (43.4% response). There were 44 surveys returned as undeliverable (1.2%). The members of the AAST were older, more likely to be male, had been in practice longer, and had greater trauma experience when compared with ENA members (p < 0.001). More AAST than ENA members (97.8% vs. 80.2%) believed that FP during all phases of TR was inappropriate (p < 0.001). Fewer AAST members believed that FP was a patient right when compared with ENA members (p < 0.0001). The AAST members were more likely to believe FP interfered with patient care and increased the stress of trauma team members (p < 0.0001). The majority of AAST and ENA members had experience with FP during TR (55.3 vs. 67.8%; p < 0.001). However, the impressions of their experiences were widely disparate, with 63.6% of ENA and only 17.5% of AAST members, indicating that the experience was beneficial (p < 0.001). CONCLUSION Attitudes toward FP during TR are significantly different between AAST and ENA members. Because of these differences in opinion, implementation of an FP policy may create conflicts between trauma team members and may interfere with the effectiveness of the trauma team.
