Delayed Presentation of a Post-traumatic Suprascapular Artery Pseudoaneurysm.

Thyrocervical trunk pseudoaneurysms are a rare entity among pseudoaneurysms, mostly caused by trauma. We present the case of a 74-year-old male who suffered a traumatic pseudoaneurysm of the supra-scapular artery after a rib and scapular fracture. The patient was treated with various interventions along the treatment algorithm, including ultrasound-guided thrombin injection, coil embolization, and surgical excision. In our patient, the pseudoaneurysm was successfully treated with coil embolization, but a persistent thrombosed pseudoaneurysm caused the patient discomfort, prompting the eventual surgical removal. This case is unique as it enlightens the step-wise approach to managing thyrocervical trunk pseudoaneurysm.

Combined Interventional Radiology and Surgical Cut-Down Approaches for Retained Gallstones.

Symptomatic retained gallstones are a rare but potentially morbid condition. Post-cholecystectomy patients presenting with vague complaints or perihepatic abscesses should be considered for retained gallstones. Traditional treatment was incision and drainage or exploratory laparotomy with washout. The current standard is minimally invasive procedures. In this case report, two different and unpublished combination methods between surgery and interventional radiology were used to extract retained stones. The first patient underwent needle-wire localization pre-operatively to identify the retained stone. The surgeon cut down along the wires and excised the stone. The second patient had a 10 French drain placed to drain the abscess surrounding the stone. The surgeon cut down along the drain, as the drain's pigtail and retained stone were located in the abscess cavity. Based on this case report, we propose using the successful method of combined interventional radiology and general surgery procedures to excise larger and deeper retained dropped gallstones.

Toxic Clostridioides (formerly Clostridium) difficile colitis: No longer a diarrhea associated infection.

BACKGROUND: Clostridioides difficile infection (CDI) is traditionally taught to be an antibiotic associated diarrheal infection. This diagnosis is based on the presence of clinical symptoms (usually defined as more than 3 watery, loose or unformed stool within 24 h) coupled with a diagnostic test. There is now a new presentation of CDI, including progression to toxic megacolon, in patients without diarrhea. METHODS: We report a case series of 9 surgical patients from a single institution who developed CDI without preceding diarrhea. RESULT: All 9 patients had CDI with positive laboratory testing for C. difficile toxin. They, however, presented with a lack of or minimal bowel movements. Six patients had rapid development of abdominal distention, 1 patient had a single episode of watery stool in 3 days, while the other 2 patients presented with constipation. Seven patients received stool softeners, suppositories and/or enemas for presumed constipation. Four patients had a mild course of infection and were successfully treated medically. The other 5 patients developed toxic megacolon, and eventually required total abdominal colectomy. Out of the 5 patients that required total colectomy, 2 expired. CONCLUSION: CDI must be suspected in patients who rapidly develop abdominal distention, vague abdominal complaints or change in bowel function even in the absence of diarrhea, especially if coupled with multi-system organ failure.

The utility of impedance cardiography in hemodynamic monitoring of patients with sepsis.

BACKGROUND: Commonly used biochemical indicators and hemodynamic and physiologic parameters of sepsis vary with regard to their sensitivity and specificity to the diagnosis. The aim of this preliminary study was to evaluate non-invasive impedance cardiography as a monitoring tool of the hemodynamic status of patients with sepsis throughout their initial volume resuscitation to explore the possibility of identifying additional measurements to be used in the future treatment of sepsis. METHODS: Nine patients who presented to the emergency room and received a surgical consultation during a 3-month period in 2016, meeting the clinical criteria of sepsis defined by systemic inflammatory response syndrome in the 2012 Surviving Sepsis Campaign Guidelines, were included in this study. We applied cardiac impedance monitors to each patient's anterior chest and neck and obtained baseline recordings. Measurements were taken at activation of the sepsis alert and 1 hour after fluid resuscitation with 2 L of intravenous crystalloid solution. RESULTS: Nine patients met the inclusion criteria. The mean age was 60±17 years and two were female; eight were febrile, five were hypotensive, four were tachycardic, seven were treated for infection, and six had positive blood cultures. Hemodynamic parameters at presentation and 1 hour after fluid resuscitation were heart rate (beats per minute) (97±13 and 93±18; p=0.23), mean arterial pressure (mm Hg) (81±13 and 85±14; p=0.55), systemic vascular resistance (dyne-s/cm- 5) (861±162 and 1087±272; p=0.04), afterload measured as systemic vascular resistance index (dyne-s/cm- 5/m2) (1813±278 and 2283±497; p=0.04), and left cardiac work index (kg*m/m2) (3.6±1.4 and 3.3±1.3; p=0.69). DISCUSSION: Through measuring a patient's systemic vascular resistance and systemic vascular resistance index (afterload), statistical significance is achieved after intervention with a 2 L crystalloid bolus. This suggests that, along with clinical presentation and biochemical markers, impedance cardiography may show utility in providing supporting hemodynamic data to trend resuscitative efforts in patients with sepsis. LEVEL OF EVIDENCE: Level IV.

Have outcomes improved in trauma patients age 90 years and older over the past decade: Experience at a level II trauma center.

INTRODUCTION: Managing trauma in the elderly is challenging and requires a multidisciplinary team approach. The aim of this study is to characterize and compare outcomes in patients 90 years and older in the last two decades. METHODS: Retrospective review of trauma patients 90 years and older admitted from 1996 to 2015. The patients were divided into two groups: Early Decade (ED) and Late Decade (LD). RESULTS: A total of 1697 patients were recorded, 551 (ED) and 1146 (LD). The mean age was 92.92 ±â€¯8(90-108)[ED] and 92.9 ±â€¯2.7(90-105)[LD] years. The most common mechanism and type of injury was falls and extremity trauma. Hospital length of stay (LOS) was shorter in the LD. There was no significant difference in in-hospital mortality or ICU LOS. CONCLUSION: Trauma admission has increased in the last decade. However, in-hospital mortality remains low. It is important for multidisciplinary teams to allocate resources to treat this elderly population.

Filling the void: a low-cost, high-yield approach to addressing incidental findings in trauma patients.

BACKGROUND: Incidental findings are prevalent in imaging but often go unreported to patients. Such unreported findings may present the potential for harm as well as medico-legal ramifications. METHODS: A chart review of trauma patients was undertaken over a year. Systems-based changes were made utilizing our electronic medical record system and our staff protocols to improve the disclosure of clinically relevant incidental findings to patients. RESULTS: During the preintervention period, 674 charts were reviewed. Trauma patients had a rate of incidental findings of 70%, and 36% of patients had clinically relevant incidentals. Rates of follow-up recommendation and disclosure to patients were 22% and 27%, respectively. In the postintervention period, of the 648 charts were reviewed, the rates of a clinically relevant incidental finding were 35%, but the rates of follow-up recommendation and disclosure to patients were 68% and 85%, respectively. CONCLUSION: Incidental findings are more prevalent herein than previously reported. With simple changes and minimal resources, clinically relevant and important improvement in reporting incidental findings can be made to mitigate the harm and medico-legal impact of an incidental finding going unreported.

Increasing use of less-invasive hemodynamic monitoring in 3 specialty surgical intensive care units: a 5-year experience at a tertiary medical center.

INTRODUCTION: Less-invasive hemodynamic monitoring (eg, esophageal doppler monitoring [EDM] and arterial pressure contour analysis, FloTrac) is increasingly used as an alternative to pulmonary artery catheters (PACs) in critically ill intensive care unit (ICU). HYPOTHESIS: The decrease in use of PACs is not associated with increased mortality. METHODS: Five-year retrospective review of 1894 hemodynamically monitored patients admitted to 3 surgical ICUs in a university-affiliate, tertiary care urban hospital. Data included the number of admissions, diagnosis-related group discharge case mix, length of stay, insertion of monitoring devices (PAC, EDM, and FloTrac probes), administered intravenous vasoactive agents (ß-predominant agonists--dobutamine, epinephrine, and dopamine; vasopressors--norepinephrine and phenylephrine), and mortality. Data from hospital administrative databases were compiled to create patient characteristic and monitoring variables across a 5-year time period, 2005 to 2009 inclusive. Chi-square for independent proportions, 1-way analysis of variance, and Kruskal-Wallis tests were used; tests for trend were conducted. An α level of .05 was considered significant. Statistical Package for the Social Sciences v14 was used for all statistical testing. RESULTS: There was a significant change in the type of hemodynamic monitors inserted in 2 of the 3 surgical ICUs (in the general surgery and neurointensive care but not in the cardiac ICU) from PACs to less-invasive devices (FloTrac or EDM) during the 5-year study period (P < .001). There was no change in mortality rate over the time period (P = .492). There was an overall increase in the proportion of monitored patients who received intravenous vasoactive agents (P < .001) with a progressive shift from ß-agonists to vasopressors (P < .002). Multivariate analyses indicated that age, case mix, and use of vasoactive agents were all independent predictors of inhospital mortality (P = .001) but that type of monitoring was not (P = .638). CONCLUSIONS: In a 5-year period, the decreased insertions of PACs were replaced by increased utilization of less-invasive hemodynamic monitoring devices. This change in practice did not adversely impact mortality.

Effect of a mandatory research requirement on categorical resident academic productivity in a university-based general surgery residency.

BACKGROUND: Our general surgery residency (46 residents, graduating 6 categoricals per year) offers the opportunity for 2 categorical residents at the end of their second year to choose a 2-year research track. Academic productivity for the remaining categorical residents was dependent on personal interest and time investment. To increase academic productivity within the residency, a mandatory research requirement was implemented in July 2010. We sought to examine the effect of this annual individual requirement. METHODS: The research requirement consisted of several components: a curriculum of monthly research meetings and lectures, assigned faculty to act as research mentors, an online repository of research projects and ideas, statistical support, and a faculty member appointed Director of Research. In July 2010, the requirement was applied to all categorical postgraduate year 1-3 residents and expanded to postgraduate year 1-4 in 2011. The research requirement culminated in an annual research day at the end of the academic year. We compared the number of abstract presentations in local, national, and international meetings between the first 2 years of the research program and the 2 years before it. We also compared the total number of publications between the 2 periods, acknowledging that any differences at this point do not necessarily reflect an effect of the research requirement. RESULTS: From July 2008 to June 2010 (Period A), there were 18 podium and poster presentations in local, national, and international meetings, and 30 publications in peer-reviewed journals, whereas between July 2010 and June 2012 (Period B), there were 58 presentations and 32 publications. In Period A 9 of 60 (15%) categorical residents had a podium or poster presentation in comparison with Period B when 23 of 58 (40%) categorical residents had a podium or poster presentation (p < 0.01). CONCLUSION: The institution of a mandatory research requirement resulted in a 3-fold increase in scientific presentations in our surgical residency. We believe that the mandatory nature of the program is a key component to its success. We expect to see an increase in the number of publications as a result of this research requirement in the next several years.

Implementation of an intern boot camp curriculum to address clinical competencies under the new Accreditation Council for Graduate Medical Education supervision requirements and duty hour restrictions.

IMPORTANCE: Today's general surgery interns are faced with increased duty hour restrictions and stringent competency-based supervision milestone requirements (ie, from direct to indirect supervision). Working within these constraints, we instituted a unique 2-month intern curriculum (boot camp) incorporating knowledge-based, experiential, and practical components. OBJECTIVES: To describe our curriculum and the effect on resident performance and teaching faculty and nursing staff perceptions. DESIGN: All interns underwent a 2-month (July and August 2011) boot camp curriculum consisting of two 2½-hour knowledge-based and procedural skills (SimMan) didactic sessions per week and completion of 25 core intensive introductory American College of Surgeons Fundamentals of Surgery web-based self-study modules, followed by a standardized patient clinical skills assessment. SETTING: Integrated general surgery residency program at the University of Connecticut School of Medicine, Farmington. PARTICIPANTS: Postgraduate year 1 general surgery categorical and preliminary residents. MAIN OUTCOMES AND MEASURES: We used several assessment tools, including an intern boot camp survey, clinical skills assessment scores, intern American Board of Surgeons In-Training Examination scores, and nursing staff and teaching faculty surveys of intern performance and aptitudes compared with the previous year's interns. Data were analyzed by independent group t test, χ2 tests of proportions, and Fisher exact test for small sample cross tables. RESULTS: In total, 84% (91 of 108) of intern respondents agreed or strongly agreed with the usefulness, relevance, and execution of the boot camp. Compared with the previous year's interns, the nursing staff agreed or strongly agreed that the cohort interns were better at patient assessment, collaboration, and effective communication and provided compassionate and respectful patient care. More than 40% (7 of 17) of surveyed teaching faculty agreed or strongly agreed that the cohort interns demonstrated better patient care and procedural skills and self-confidence compared with the previous year's interns. The clinical skills assessment scores after the 2-month boot camp paralleled the scores typically seen at the end of the previous 2 internship years (P > .25 for all). The proportion of nondesignated and categorical interns pursuing careers in general surgery scoring in the top quartile on the American Board of Surgery In-Training Examination increased from 7% (2 of 28) to 50% (5 of 10) compared with the previous 2 internship years (P = .01). CONCLUSIONS AND RELEVANCE: Recent changes in intern duty hours and supervision rules mandate that residency training programs must institute a competency-oriented curriculum to provide interns with the necessary knowledge and practical skills to attain clinical competence.
